RealLife manipulators appear convincing and interested in your own good, and soothe one in by being nice, kind, getting your sympathy and if that doesn't suffice for them to get everything they want, they begin pushing buttons as they lie whenever they can get away with it. All of that is so subtle that it usually escapes the people who it is happening to.

But in fiction, manipulation is usually just the result of the victim carrying an IdiotBall. Everyone else, especially the audience, can and will immediately identify the manipulator as evil, but the manipulated is simply a Horrible Judge Of Character. Compare to when only the protagonists see through the manipulator and everyone else holds him in high regard, in that case it's a DevilInPlainSight. Compare to The AlphaBitch who is quite often also transparently mean, abusive and treacherous to everyone (who doesn't have the authority to punish her for it), yet inside her clique (read: "popular" and/or upper-class people), magically everyone likes her.

When the plot requires for this Horrible Judge Of Character to regularly make {{Card Carrying Villain}}s his most intimate confidants, they're TheIngenue--or TooDumbToLive. Innocence and helplessness may attract guardians and friends, but will also make them vulnerable targets to get romantically involved with TroubledButCute or TheVamp.

On the extreme end, the FriendToAllLivingThings will also be intensely [[TrueCompanions loyal to their friends]], so they'll [[SelectiveObliviousness ignore all evidence]] that the Manipulator means them harm. When true friends try to point them to suspicious behavior or even show outright damning evidence, they will get a pouty "[[YoureJustJealous You're just jealous of our friendship]]!" and be blown off as TheCassandra, probably earning an earful about how Baron Bloodlove is a wonderful human being who just happens to be around whenever someone's bloodless corpse is found.

It usually takes a [[DidYouActuallyBelieve point blank]] [[EvilGloating Evil Monologue]] from their "friend" over the [[TrueCompanions True Companion's]] corpse to even ''faze'' them into considering the possibility they might not be as hug-tastic a friend as they thought. If it doesn't [[BreakTheCutie break them]], then they'll just turn right back around and [[LoveMartyr follow their "friend" around]], say he [[EasilyForgiven forgives them for killing off thousands]] and [[BetrayalTropes betraying him completely]], and insist the PowerOfTrust and [[ThePowerOfFriendship Friendship]] will [[LoveRedeems redeem them]].

This [[HeelFaceTurn may]] or [[DesignatedVillain may not]] work.

HeroWithBadPublicity is the reverse of this, where a character who is considered evil is actually good. If it's romantic, expect a LoveMartyr, LoveMakesYouDumb or MadLove. If the "friend" is a {{Chessmaster}}, then they're an UnwittingPawn. If the horrible judge of character causes a horrible plot development by doing this, they are an UnwittingInstigatorOfDoom. Related is PacifismBackfire, where someone chooses not to act violent against someone else; one reason is that he still believes that someone is still good. Contrast EvilCannotComprehendGood. In larger numbers, expect to get GullibleLemmings.



[[folder:Anime & Manga]]
* In ''Anime/{{Gankutsuou}}'', Albert is a Horrible Judge of Character. He ignores the strange coincidences when the count arrives in Paris, the horrible turns of events, the letters to his father. Even when his childhood best friend pleads with him that he be careful around the count, all he gets are ''tantrums''. The count, being a {{Magnificent|Bastard}} and ManipulativeBastard counted on this, and systematically destroys Albert's remaining confidence in him by slowly spelling out how he was a piece in his schemes for revenge… and does so precisely in the most heartless manner possible to get him to challenge him to a duel and get a legal excuse to kill him as a revenge against his parents.
* In Manga/DragonBall, Goku is this at least once every season. Then again, DefeatMeansFriendship results in Goku being right… eventually. Though his inability to read people has gotten him killed. [[DeathIsCheap Twice]].
* ''Franchise/{{Gundam}}'':
** [[TheFederation the Earth Federation]] from [[Franchise/{{Gundam}} the UC]] is this.
*** In [[Anime/MobileSuitGundam0083StardustMemory 0083]], they give total power over the colonies to Jamitov Hymen and Bosque Ohm, who at the very least [[spoiler:failed miserably to stop [[ColonyDrop Operation Stardust]] and at worst ACTUALLY ALLOWED IT TO HAPPEN]].
*** Jamitov himself is one of these in ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]''. He chooses Bosque as his [[TheDragon Dragon]], Jerid Messa as his disciple, and recruits Paptimus Scirocco from the Jupiter Energy Fleet, giving him the best ship in the fleet and allowing him to accumulate a great deal of power under him. The thing is, [[InsaneAdmiral Bosque]] doesn't care about Jamitov's agenda and just wants to kill every Spacenoid he can catch, [[DeceptiveDisciple Jerid]] plans to eventually supplant Jamitov, and [[DarkMessiah Scirocco]] plans to supplant Jamitov [[TheStarscream without the 'eventually']].
*** By ''[[Anime/MobileSuitGundamCharsCounterattack Char's Counterattack]]'' they show no signs of improvement in spite of all this. The deal they cut with [[FallenHero Char]] basically amounts to: "In return for not dropping your space rocks on us, we'd like to give you [[spoiler:a giant space rock! And as an extra bonus, it's loaded with nukes!]]"
*** Really, after a certain point it stops being humorous and becomes worrying. One has to wonder if the Earth Federation has a terrorist insurance policy on the planet Earth and is desperately trying to cash in on it.
*** This eventually comes to a resolution in ''[[Manga/MobileSuitCrossboneGundam Crossbone Gundam]]'', where it's revealed that [[spoiler:the Jupiter Energy Fleet has been manipulating both the Federation and the various incarnations of Zeon, with their stated goal under Fonse Kagatie being to weaken the Feds enough to where they can eventually overthrow them and establish total hegemony over the Earth Sphere]].
** In ''[[Anime/MobileFighterGGundam G Gundam]]'', there's Chairman ([[spoiler:later Prime Minister]]) Karato. Though that could be somewhat explained by how much of a [[ManipulativeBastard Manipulative]] ''and'' MagnificentBastard his TreacherousAdvisor [[spoiler:Urube]] is.
* ''Anime/MazingerZ'': In one of the last chapters of the manga penned by Gosaku Ota we were introduced to Yumiko Shiozai--TheHero Kouji's grandmother. She met Hell in college when she was a student, and she thought despite his quirkiness he was a good person. [[MadScientist Dr]]. HELL. As well known as the BigBad. His sanity was already slipping, he was beginning to look ObviouslyEvil and he was troubled and paranoiac and prone to KickTheDog. Oh, and [[StalkerWithACrush he stalked her]]. Obsessively.
* From ''Manga/{{Doubt}}'', we have Yuu. A [[NiceGuy nice guy]] who is stuck with his friends in an abandoned place and one of them is killing the others. And despite one of their members being a delinquent with a HairTriggerTemper who was willing to ''beat him up'' after Yuu accidentally bumped into him and another is an aloof, mysterious guy who seems to know more than he lets on, he still thinks it's all an outside job. Though he eventually does wonder in later chapters whether one of them ''did'' kill everyone in their group.
* Lithuania from ''Webcomic/AxisPowersHetalia''. His boss Russia is a male {{Yandere}}, his crush Belarus is Russia's sister ''and'' a Yandere as well, his best friend is the often selfish Poland (though in Poland's defense, he ''does'' attempt to help him with Russia more than once, and clearly stands up to Russia in ''Meeting of the World''). However, this trope only applies to his one-sided crush on Belarus, as he expresses frustration in dealing with Russia and Poland, and deals with them because he has to, and he makes the best of a bad situation.
* In ''LightNovel/FateZero'' Kirei Kotomine seems to simply inspire trust. Risei trusts him unconditionally (though this is kind of justified as Kirei is Risei's son) and Tokiomi Tohsaka notes that he seems more nihilistic than faithful or religious… yet he also trusts him immensely and it never occurs to him that Kirei might not be the most loyal person on earth. Even Assassin believes that Archer (aka Gilgamesh) is no problem at all when Assassins are implied to ''never'' get into direct fights. Bazett also trusts Kotomine a bit too much.
** Tokiomi eventually takes this to ridiculous extremes by [[TooDumbToLive writing what is essentially his will, which says Kirei gets everything (including his daughter)]], [[TooDumbToLive giving him a]] ''[[TooDumbToLive knife]]'' [[TooDumbToLive as a parting gift, then walking away from him with his back turned]]. You can guess how well ''that'' ended. He also gave his youngest daughter to Matou Zouken, with [[AbusiveParents predictable]] [[RapeAsBackstory results]].
* Tsuna from ''Manga/KatekyoHitmanReborn'' is this, somewhat. He ''does'' realize that the villains aren't the nicest people on earth, but is very naive about wishing to believe the best in people (namely, Rokudo Mukuro). It's lampshaded by several characters in the series (yes, even by the villains themselves).
* For most of ''TheTwelveKingdoms''' first StoryArc, [[spoiler:Yuka Sugimoto]] swears complete loyalty to the King of Kou despite several indications that he is simply using her and cares for nothing but himself. Even after being [[spoiler:abandoned on a remote, barren farm]], she makes up an excuse for it herself and remains eager to do his bidding. Sure, the girl ''is'' [[IJustWantToBeSpecial desperate to be the heroine]], but ''still''!
* Prince Diamond of season 2 of ''Anime/SailorMoon'' refuses to hear anyone question the motives of his adviser Wiseman. A skeleton with glowing hands and eyes. Who wears a BlackCloak. Who had previously appeared before them very suddenly offering them his wisdom and the power of the [[ObviouslyEvil Evil Black Poison Crystal]]. In his defense, he's also the ruler of a planet of people exiled by the kingdom of Crystal Tokyo, so he's not stable. This all only applies to the anime, because in the [[Manga/SailorMoon manga]], the Black Moon Clan were evil and Demand was pure evil, so nobody really cared much about Wiseman since they were all after the same goal.
** In the same story line and also in the anime, Cooan is revealed [[LoveMartyr to be in love with Rubius]], who is completely evil and clearly using her. Learning the obvious is what leads her and the other three Ayakashi Sisters to their HeelFaceTurn.
* A cynic could very well consider Akane Tendo of ''Manga/RanmaOneHalf'' to be one of these. She is convinced that Ryoga Hibiki is a sweet, gentle, kind-hearted person and her best friend. While he ''does'' make some good character growth, Ryoga is very flawed as well: petty, melancholic, obsessive, childish, and obsessed with wooing her, and her blindness to his romantic intentions is one of the things that upsets him the most. She blatantly ignores things like the fact he was once part of a plot to kidnap her because he does things like choke down her [[LethalChef repulsive food]] and lie that it tastes delicious, immediately leaps to assault Ranma when Akane gets angry or upset, and otherwise goes out of his way to stroke her ego. In fact, it's possible that ''this'' is the keystone behind her apparent inability to realise he is really her pet pig P-chan: she thinks so highly of him that she can't conceive he would abuse her trust and stain her honor the way that pretending to be an animal so he can, among other things, sleep in her bed.
** Given her trust levels for Ranma, the same could be applied there. While Ranma is hardly a model citizen, Akane is generally willing to accuse Ranma of all sorts of immoral actions that he would never take, or has shown any sign of taking. Most notably is her insistence that Ranma is a pervert, despite the fact that Ranma never shows any kind of lust and never abuses his GenderBender curse to go peeping. Ranma is guilty of many things, but he is all but immune to lust.
* Elmer C. Albatross and Graham Spectre from ''LightNovel/{{Baccano}}!''. Elmer is thoroughly convinced that even the biggest monster secretly has a heart of gold and happens to be [[HeterosexualLifePartners best friends]] with MadScientist/terrorist Huey Laforet. As for Graham? Well, he {{Hero Worship|per}}s ''[[AxCrazy Ladd]] [[ChaoticEvil Russo]]''.
** Though in Graham's case, he [[AxCrazy isn't that different from Ladd]] personality-wise. It's just as likely that Graham is well aware of what kind of man Ladd is, but is so violently insane himself that he likes it!
* Catherine Gregory from the manhwa ''BurningHell''. Okay, so she led a sheltered life and can't understand Korean or Japanese, but the two guys she's stuck with are AxCrazy and make no bones about it and look her in the eyes with {{Slasher Smile}}s, and she even compared their fighting a common foe to a two-headed demon; and she '''still''' considers them to be kind-hearted saviors! When you think that about a guy who wants to [[IAmAHumanitarian eat you]] and another who considers you prime material for a [[MadDoctor Body Works-type]] "[[MadArtist work of art]]," you're getting pretty close to TooDumbToLive.
* Kaito from ''Anime/YuGiOhZexal'' may not have ''completely'' trusted his father, Dr. Faker, but the fact that he believed him at all or that any of what he was telling him was the truth was likely Kaito's biggest fault.
** Of course, [[spoiler:Dr. Faker himself was an even bigger example. Believing Vector's promises to help Haruto--which were obviously lies--caused him to commit numerous atrocities that may have made him an accomplice to genocide. (And technically still might, unless the heroes are victorious.)]]
* Bear Walken of ''{{Gungrave}}'' trusted Harry [=McDowell=] with both the fate of Millenion ''and'' his ''daughter''. Bear Walken was a good Mafia boss but apparently terrible with people.
* ''Manga/{{Bleach}}'s'' Momo Hinamori is an especially unlikable example of this, although her denial is partly caused by the trauma of having to recognize that her trusted mentor is actually a murdering, tyrannical rebel bent on warping your mind for his own convenience.
* In ''WeissKreuz'', Ken Hidaka is quite convinced that his childhood friend [[JerkAss Kouichiro Kase]] can't possibly know what his evil boss is up to. One murder and an attempt on Ken's own life later, he wises up to Kase's conniving ways, but it takes ''another'' attempt on Ken's life before he actually does anything about it--which, for those of you playing along at home, would be the ''third'' time Kase's tried, and failed, to kill him.
* ''Anime/CodeGeass'' is just chock full of them, from Suzaku to [[spoiler:the Black Knights, when Schneizel fools them into betraying Lelouch]].
** And Nunnally, who [[spoiler:believes Schneizel when he says that he evacuated Pendragon before nuking it]].
** Lelouch could count too, as his decisions to use and manipulate Rolo and Viletta in R2 end up become a good part of his further descent into insanity that eventually resulted in his [[spoiler: decision to do the Zero Requiem plan. ]]
* ''Manga/FullmetalAlchemist''.
** May thinks [[DirtyCoward Yoki]] and [[AxCrazy Scar]] are good guys long before CharacterDevelopment hits either of them. She also mistrusts the ''Elric brothers'' for a while, probably because she thought Ed had "lied" to her about being tall and handsome as opposed to short (in reality, she just [[{{Cloudcuckoolander}} thought this up herself]] and took her disappointment out on him). There's also the fact that they were Scar's enemies... Things don't work out so well for her when she decides to trust Envy, though.
* ''SakuraGari'': Masataka. Honestly, there are all these horrible rumors about Souma, Souma himself acts really weird, strange events keep occurring, and... he just thinks Souma is a nice master. Right.
* Ayase of ''Manga/OkaneGaNai'': his cousin ''sold him to the Yakuza'' and he thinks it was just a "misunderstanding." This is also the guy who surrounds himself with "friends" who - without exception - are trying to get in his pants. And he keeps thinking that it's also just a "misunderstanding" when one of his "best friends" tries to rape him. Twice. And then chain him to a bed post in his room. Aaaand he lives with the loan shark who ''bought him'' from said cousin. For more details just look in the TooDumbToLive entry. He's there too.
* Araki of ''Hana to Ryuu'' (prequel to ''Manga/{{Kizuna}}'') doesn't seem to notice that his most trusted employee has all the qualifications of psychopath, rapist, murderer and torturer, despite the fact that he tried to drive his boyfriend to suicide, is constantly trying to kill him, and [[spoiler:murdered Araki's wife who was ''pregnant with his unborn child'']]. Yeah, he's [[SarcasmMode just a great guy]].
* Asuna's father in ''LightNovel/SwordArtOnline'' thinks Sugou is a friendly, bright little protege, and arranges a marriage between the two without noticing that his daughter hates the evil bastard. Later, after it becomes clear that Sugou [[spoiler: is the reason Asuna and a hundred others stayed in their comas a few extra months, and that Sugou was planning on brainwashing/raping her]], [[MyGreatestFailure he resigns from his position as CEO, and Asuna is only barely able to convince him not to retire outright]].
* Like the game it's based off, the XY arc of ''Manga/PokemonAdventures'' has Professor Sycamore praising Lysandre despite the fact that Lysandre is obviously '''insane'''. What makes it worse here is that ''everyone else'' can see it and reacts accordingly, whether it being with fear or suspicion, while Sycamore continues to defend him with light and sparkles in the background.
* When the ''{{Anime/Pokemon}}'' gang first meets Barry, he admires Ash's rival Paul, and consider Ash (and Dawn) inferior trainers compared to Paul. Barry cast this opinion after watching the Hearthome Tag Battle TournamentArc on TV, the very same competition where Paul blatantly quits in the middle of a battle for petty reasons[[note]]his Chimchar couldn't fight properly, not just because of its phobia of Zangoose (which the opponent was using), but also because Paul didn't let the chimp rest after putting it through TrainingFromHell the previous night[[/note]] leaving his tag-team partner, Ash, to win the fight for their team on his own.
** In the Kalos arc, Alain is this to Lysandre. Lysandre gets Alain to help his goals to use Mega Evolution for peaceful purposes, when in reality he's been the mastermind behind almost everything that happens in the Mega Evolution specials and eventually the main series once Team Flare makes their appearance.

[[folder:Comic Books]]
* ComicBook/BettyRoss actually fell for Glenn Talbot, a JerkAss at best, and a sociopathic SmugSnake at his worst.
* Susan of ''ComicStrip/{{Candorville}}'' has made some pretty bad decisions, such as trying a bit of OperationJealousy on her [[ObliviousToLove oblivious friend]] Lemont (it doesn't work; not only does [[IWantMyBelovedToBeHappy he want her to be happy]], it leaves him open to pursue an online relationship with his college crush, [[LoveDodecahedron who happens to be Susan's married ex-best friend]]) or adopting a dog that's obviously a wolf [[spoiler:that might be Lemont's vampire baby mama in disguise]].
* This is pretty much King Max's defining trait in ''ComicBook/ArchieComicsSonicTheHedgehog''. He trusted the original Dr. Robotnik to the end and never suspected his true colors until it was too late. Issue 233 reveals him to have a history of this; Harvey Who explicitly warned him ''not'' to trust Warlord Kodos, ''not'' to let Ixis Naugus remain in the kingdom, ''not'' to exile Nate Morgan, and finally ''not'' to take the original Robotnik in, but Max ignored him ''every single time''. There's a reason he's been given the title of Maximilian the Cursed.
** This is actually justified. Way back in issue [[http://archiesonic.wikia.com/wiki/Archie_Sonic_the_Hedgehog_Issue_58 58]] Max explained that every ruler would bathe in the [[http://archiesonic.wikia.com/wiki/Source_of_All Source Of All]] and receive it's guidance in times of crisis. Though why the Source manipulated Max the way it did was never explained.
* Subverted in ''ComicBook/{{Fables}}''. Ambrose, who up until the 8th book had been a [[TheDitz not too bright]] NiceGuy sets out to restore his kingdom in the homelands. He recruits dead fables in the Witching Well, promising them a physical body and a chance at redemption for their sins. This includes Shere Khan and Bluebeard, both of whom betrayed the fable community and plan to betray him for control of his kingdom. Not only does Ambrose know, it's all part of his {{plan}}.
* ''ComicBook/SpiderMan'': examples:
** The idiot who authorized giving ComicBook/NormanOsborn the authority he had during ''ComicBook/DarkReign'' fits the list, plain and simple. (It was at first assumed to be President UsefulNotes/BarackObama, due to the shade of the hand presenting Osborn, but it was later retconned that Obama's [[UsefulNotes/GeorgeWBush predecessor]] was the one holding the IdiotBall.)
*** And although even his son Harry told him off during that mess, after the events of ''ComicBook/SuperiorSpiderMan'', [[spoiler: Harry's former wife and Peter's former friend Liz Allan]] has been seen in a new alliance with Norman Osborn as he attempts to establish a new identity and corporation (now that his identity as the ComicBook/GreenGoblin is no longer a secret). Whether [[spoiler:she]] is doing this entirely out of free will is unknown, but it's very possibly that the biggest reason is [[spoiler:to ensure a better future for her own son]].
** Aunt May was played like this a lot in the 1960s, especially with regards to "that awful Spider-Man" and Doctor Octopus (who charmed the socks off her and almost married her). That she liked to tell Peter that bohemian party-girl Mary Jane would make a good future wife for him seemingly was another instance of this, but in the 1980s it turned out that she was actually right.
** A minor example involving Spider-Man: When Joe Robinson was in legal trouble for withholding evidence in a murder involving [[EvilAlbino Tombstone]], Joe's attorney Cynthia Bernhammer starting dating Nick Katzenberg, a sleazy tabloid paparazzi with no morals who specialized in making celebrities, including Spider-Man, look bad. In fact, she was the only person who didn't hate him, and even ''she'' wondered at one point why she was attracted to a "lowlife worm" (as she put it) like him. Although, it's not known what became of their relationship, as Cynthia stopped appearing after Joe was pardoned, [[spoiler:and Nick was eventually killed off]].
** Of course, that was nothing compared to Glory Grant, J. Jonah Jameson's secretary at the ''Daily Bugle''. Her one-time lover Edwardo Lobo was a Mexican mobster ''and'' [[OurWerebeastsAreDifferent a mutant werewolf]]; she didn't know at first, but even after she found out, she was okay with it! She continued to love him until the very end, [[spoiler: when a gang war between the Lobos Syndicate and ComicBook/TheKingpin's organization concluded in a violent and bloody melee, which resulted in Spidey grappling with Edwardo in werebeast form. Glory grabbed a gun that had been dropped by the Kingpin's NumberTwo, and actually tried to shoot Spider-Man to save Edwardo; but she missed, hitting Edwardo instead and killing him]].
* The braintrust in charge of the cloning programs in ''ComicBook/SupermanAtEarthsEnd'' decided to pass over the likes of ElvisPresley, ComicBook/LexLuthor, and UsefulNotes/JohnFKennedy, to [[YouClonedHitler clone Hitler]]. ''Twice''.
* ''ComicBook/{{Iznogoud}}'': The Caliph has Iznogoud as a vizier. You do the math.

[[folder:Comic Strips]]
* [[http://joshreads.com/?p=2706 The Comics Curmudgeon]] has a ''lot'' of fun pointing out how Adrian and later her father from ''ComicStrip/MaryWorth'' fit this mold.

[[folder:Fan Works]]
* Vale Whitaker, the heroine of the HungerGames fanfiction ''Fanfic/SomeSemblanceOfMeaning'', is awful at discerning the true alignments and motivations of others. Even in the arena, she wants to trust others, which leads to her [[spoiler: allying with Phlox, who tries to kill her and her other allies]]. However, the one person that she consistently distrusts is Obsidian, who is quite kind to her, all things considered, and even [[spoiler: saves her life on multiple occasions]].
** Later on, [[spoiler: during their alliance]], we learn that Vale also misjudges Obsidian by thinking that, as a well-trained and strong Career, he must not have any problems, while he is simultaneously [[spoiler: plagued with constant questions about the morality of his actions, as well as the fear that he is NotSoDifferent from Amber and the other Careers]]. Obsidian also misjudges Vale by mistakenly assuming that she is a PuritySue type who could never hurt anyone and therefore lacks the kind of worries that consume him.
* In ''Fanfic/ThePrayerWarriors'' Jerry, the main character, qualifies on no less than three occasions in "[[Literature/PercyJacksonAndTheOlympians The Evil Gods Part 1]]". In the space of a single chapter, there are two cases- when he believes Ethan when he repents his sins, but [[HeelFaceDoorSlam kills Thalia when she tries to do the same]] on the mere chance that she's lying- the former turns out to be a traitor, while the latter joins the Prayer Warriors in "The Evil Gods Part 2", and is [[RetCon retconned into being one all along]]. He also doesn't realize that his own wife is a traitor, and that he's not the father of her unborn son. Interestingly enough, he has (so far) not ended up regretting deciding to trust the canonical traitor [[spoiler:Luke]].
* In [[Fanfic/Gensokyo20XX Gensokyo 20XXV]], we have Reimu, who is noted, in one chapter, to be someone who can bullied one minute and still go back around trust them the next", which is true seeing that she trusted Paintbrush Bitch, when the latter let her outside, knowing full well that could place her in danger and it did. Naturally, one of the kids thought of her as a moron for doing that, to which Alice did bring up the fact that she could have thought of it as being nice by doing something the other adults wouldn't do. In that vein, Ren gave his brother a thinly veiled threat about what could happen if Baka dared to betray said trust.
-->'''Ren''': On a note and you had better get this through your thick skull and make clear note of which it is I am saying to you now, you can bully Reimu one minute and, yet, she'll still trust you the next, so, in no way, are you to violate that trust or place her into harms way and, if you do, well, we will never at all hesitate and will act as we see best, be you my older brother or not.
* ''FanFic/RosarioVampireBrightestDarkness Act III'': Akua and Kahlua helped Kiria in his plan to [[TimeTravelForFunAndProfit use the Chrono Displacement spell to rewrite history]], going so far as to steal said spell from their father Issa's archive for Kiria to begin with, because they genuinely believed that the extent of Kiria's plan was to send Tsukune's [[SuperPoweredEvilSide ghoul]] back to the [[GreatOffscreenWar Battle of Kahdaln]] so as to turn the tide of the battle and change history in favor of the monsters, thus ensuring that monsters would rule the world. In chapter 52, upon their defeat, the two are completely shocked, ''shocked!'' to discover that, in addition to that, Kiria also planned to send out [[PsychoSerum Blackheart-infected]] monsters to the dark lords themselves, as well as any other being powerful enough to oppose him, so he would be the top monster in the revised timeline, and he would have had Akua and Kahlua, and possibly Moka and Kokoa as well, infected with Blackheart as well and sent back to kill their father Issa and destroy the Shuzen empire from within, all of which is [[NotWhatISignedOnFor anything but what they wanted]]. Kahlua and Akua spend the entirety of Act IV as {{The Atoner}}s.
* ''Fanfic/BartSimpsonAttorneyAtLaw'': Teenage Maggie toward [[BastardGirlfriend Gina]]. Her idolization of Gina leads her to ignore the damage she has done toward Bart, and gets [[WhatTheHellHero an earful from him and Marge]] for reintroducing Gina to him. [[spoiler: Gina joins in a plot to kidnap Bart on behalf of Jessica Lovejoy. However, she does end up redeeming herself by testifying against Jessica, thanks to Maggie's never-ending faith]].

[[folder:Films -- Animation]]
* The Sultan from Disney's ''Disney/{{Aladdin}}''. The movie even {{lampshade|Hanging}}s this when the Sultan provides the above page quote about priding himself to be an excellent judge of character, and Iago grumbles his sarcastic "NOT!"
* ''Disney/BeautyAndTheBeast'' has the villagers being completely, legitimately loyal (as in, they willingly love and are not forced to love him out of fear) to Gaston, a man who not only has shown himself to be a self-centered, arrogant {{Jerkass}}, but has no qualms of expressing it, reaching an all new low when Gaston and [=LeFou=] blatantly state to the entire bar that their plan involved arresting Maurice under false accusations of being a dangerous madman in order to marry Belle, and they still supported him.
** Then again, perhaps the villagers are just as bigoted as he is.
* ''Disney/{{Pinocchio}}'', both in the Disney film, and in the Creator/{{Filmation}} unofficial sequel, ''WesternAnimation/PinocchioAndTheEmperorOfTheNight''. He seems to think he can trust ''absolutely everyone'' he comes across. Worse yet, he often trusts people that ''[[TooDumbToLive he's well aware have double crossed him before]]''. In the latter, he willingly makes deals with a boatman with [[RedEyesTakeWarning glowing red eyes]] aboard a ship referred to as "The Empire of the Night."
* Yet again from the Franchise/DisneyAnimatedCanon, Mufasa from ''Disney/TheLionKing'' may get angry at his younger ObviouslyEvil brother Scar, but still trusted him as a family member. This leads Scar to manipulate Mufasa to get him killed. However, he didn't particularly *trust* Scar; he just didn't think his brother was really evil enough to commit regicide. Furthermore, the movie was a Disneyfied version of ''Theatre/{{Hamlet}}'', and Mufasa made the same mistake Hamlet's father made.
* ''AGoofyMovie''. Goofy is convinced that his {{Toxic Friend|Influence}} Pete is "good with kids," despite Pete more-or-less [[AbusiveParents mentally abusing his son]] for ''[[WesternAnimation/GoofTroop years]]. When Pete hears of Max's aloofness, he presents as a concerning issue that Max may end up becoming a criminal. Goofy initially shrugs it off, but the notion returns when he is called by the very neurotic principal over the stunt Max pulled. The principal rants in extreme hyperbole, leading to Goofy taking Max on the fishing trip. Then later Pete convinces Goofy that the way to keep your kids good is to "keep 'em under your thumb", demonstrating [[KickTheDog at least partially without reason]] that all that does is make your kids miserable. Overall, it fails as Goofy tries being more assertive, which doesn't work. This leads to more problems when Pete discovers Max editing the road trip map.

[[folder:Films -- Live-Action]]
* During his brief appearance in ''Film/VanHelsing'', Victor Frankenstein acts shocked, ''shocked!'' that Count {{Dracula}} had ulterior motives in financing his [[ForScience scientific experiments]] other than for the science of it... even as said patron uses horror movie teleportation to saunter calmly around his laboratory as peasants with TorchesAndPitchforks [[StormingTheCastle storm the castle]].
* In the mystery film ''Film/AfterTheThinMan'', Nora Charles's cousin Selma chooses one man over another to marry. The "winner" proves to be a [[spoiler: cold-hearted philanderer]] while the "loser" is [[spoiler: finally revealed to be a raving madman]]. Selma's mother: "You sure can pick 'em!"
* [[InMediasRes Before the beginning]] of ''Film/{{Sanjuro}}'', a group of young samurai incorrectly identify the corrupt official in the clan, and plan to root him out. This would have played out perfectly for the actual corrupt official if a certain [[NoNameGiven nameless ronin]] hadn't been eavesdropping.
* The live action ''Film/HowTheGrinchStoleChristmas'' embellishes Cindy Lou Who's encounter with the [[PaperThinDisguise Santa-disguised Grinch]] as he's stealing her home's Christmas trappings. She tells him that the Grinch isn't a bad person, just lonely. The Grinch remarks to himself that she's a "nice kid", but a "baaad judge of character". Given his later [[ItWasHisSled change of heart]], it turns out she was spot on after all, and it's actually he who falls into this trope.
* Alan Garner from ''Film/TheHangover'' is dumbfounded when he finds out that he was sold roofies instead of ecstasy because the drug dealer "seemed like a real straight shooter". He also remains friends with Leslie Chow in the sequels, despite knowing full well that he's an international criminal.
* In ''Film/{{Fallen Angel|1945}}'', June Mills is an intelligent woman, but she still falls in love with and marries a man who she knows conned her hometown of Walton.
* For most of the ''Franchise/StarWars'' prequel trilogy, it seems that nearly everyone—especially Anakin—thinks Chancellor Palpatine [[ReasonableAuthorityFigure is a great guy]]. However, the Franchise/StarWarsExpandedUniverse suggests that by the time of ''Film/RevengeOfTheSith'' the Jedi ''didn't'' trust Palpatine- they thought he was a fairly typical slimy politician. They just didn't suspect him of being Darth Sidious because he was ''too obvious''—he was [[HiddenInPlainSight hiding in plain sight]]. This might be justified if you believe Palpatine was using his Sith Force powers to cloud their judgment and mask his Sith nature.
* Ralphie, from ''Series/StormOfTheCentury'', who insists that Andre [[SignificantAnagram Linoge]], who has been responsible for five deaths so far and is heavily implied to be ''TheDevil'', isn't a bad guy because he gave Ralphie a present, and "bad guys don't give kids presents." To be fair, Ralphie is about 5 years old.
* ''Film/GuestHouseParadiso'': Gina Carbonara thinks the pervy, condescending Richie is a sweet man, and believes she can trust Eddie with her identity, only moments after meeting him. (Compared to her BastardBoyfriend, however, those two are saints).
* Mick in ''Idiot Box'' looks up to his friend Kev, unaware that Kev is a sociopath. He remains unaware even as he starts to move beyond Kev's influence and realize he can make more of his life than Kev ever could.
* ''Film/TheDarkKnightSaga'': Batman/Bruce Wayne is this way for at least one villain per film.
** In the first film, there is Ra's Al Ghul, a mentor who proved to be an extremist sociopath.
** In the second film, there is Harvey Dent, who proves to be NotSoAboveItAll when pushed over the edge by the Joker.
** In the last film, there is [[spoiler: Miranda Tate/Talia al Ghul]]. Also he puts a lot of faith in Selina Kyle, and ends up (in his own words) "disappointed." [[spoiler:It's subverted in the end, where the faith he has in her ends up bringing out her good side]].
** He also tends to underestimate the assorted {{Big Bad}}s in each film:
*** When the Joker appears, Batman, somewhat hypocritically, dismisses him as just one man who couldn't possibly be more dangerous than the mob. He ends up destroying quite a bit of the city, [[EvilerThanThou driving the last nail into the mob's coffin]] [[NearVillainVictory and almost doing the same for Batman]], and [[TheCorrupter drives Harvey Dent to madness]].
*** Later, Batman, who has been out of action for roughly eight years, gets back in the batsuit, and is able to hunt down and capture several League of Shadow members who were trying to escape a bank robbery. The primary villain Bane manages to get away. Batman dismisses Bane as just another one of Ra's al Ghul's flunkies. When Bruce and Alfred review tapes of Bane's assault on the bank, Bruce brushes away Alfred's assessment of Bane's combat abilities, stating that he'll simply "fight harder". He teams up with Catwoman to go underground and take out Bane, only to be outsmarted by Bane and lured into a trap. It's only thanks to the ensuing CurbStompBattle that Batman realizes just how dangerous Bane really is.
* In ''Film/{{Byzantium}}'', what's with nice guy Darvell later thinking [[spoiler: Ruthven might be a good, noble recruit for the Brethren? Ruthven raped and forced Clara into whoredom and then abandoned Darvell, robbed his corpse, and stole his estate. WTF?]]
* ''Film/TheHungerGames'': One of Katniss Everdeen's biggest flaws. Quite simply, she has a nasty habit of always assuming the worst of everyone she meets when these people ironically often end up saving her life and or genuinely caring about her. Her trust issues mostly stem from her childhood trauma of never having anyone to be there for her and in turn having to be there for her younger sister.

* Pinocchio in ''Literature/TheAdventuresOfPinocchio'' is far too trusting in people he shouldn't. This is most notable with the Fox and the Cat, who are really interested in stealing the money Mangiafuoco gave to Pinocchio. Before they do the theft, there are too many clues that they are not the good guys they pretend to be: they clearly keep feigning handicaps, call Pinocchio in a pretty suspcious way, tell Pinocchio that school is the reason for their handicaps, kill a blackbird that tries to warn Pinocchio, leave Pinocchio to pay for all the food they ate, arrange a meeting in midnight and almost kill him (they were disguised, but Pinocchio managed to bite off the Cat's paw and could have discovered all). But Pinocchio still believes their lies until the theft. Later, Pinocchio trusts the worst students in his class, even if his teacher and the Fairy advised him not to. For that, those students trick him to skip school and when one of them gets hit and faints, the rest scapegoat Pinocchio.
* The elder princesses of the country where ''Literature/ABrothersPrice'' takes place seem to have been this. They and the husband they chose are already dead at the beginning of the novel, but the trauma caused by said husband is still very alive. Because of the polygyny practiced in their culture, all their sisters suffered from their bad taste in men.
* This is very much true of the character Squire Allworthy in ''Literature/TomJones''. He's supposed to be a ReasonableAuthorityFigure, but throughout the novel, he always makes the wrong judgments, trusting bad characters and assuming the worst about the heroes to the extent that his reasonableness is InformedAbility.
* In both ''Literature/TheDaVinciCode'' and ''Literature/AngelsAndDemons'' Robert Langdon unwittingly helps the villain achieve his goal while running scared from the guy who is trying to warn him about it.
** Seeing as "the real BigBad is [[BigBadFriend actually the person who has been apparently helping the protagonists the most]] and has no logical reason to ''be'' the Big Bad" is one of the ''[[StrictlyFormula many]]'' common elements to all of Creator/DanBrown's work, this may be a case of GenreBlind instead.
* ''Literature/WutheringHeights''. Lockwood originally describes Heathcliff as "a capital fellow". But then after storytime with Nelly...
* In the ''Literature/ChroniclesOfThomasCovenant'' The Lords of Revelstone gave a seat on their council to the being that would later become known to them as Lord Foul the Despiser (Also [[IHaveManyNames Satansheart and Soulcrusher, Corruption, the Gray Slayer, etc etc]]). They did give him gifts they thought should have revealed any ill intent but he was too powerful for them to work. Still a horrendously bad judgment on their part.
* In [[Literature/TheBible The Book of Esther]], Ahasuerus did't realize that his vizier Haman is an EvilChancellor, even when he tried to wipe out all the Jews in Persia, until Ahasuerus realized that this would also include his wife, the titular Esther. To be fair, she was concealing her nationality from him. He trusted Haman so much that all Haman had to say was "let me take care of this group of non-law-abiders", and he got ''the king's signet ring to use''.
* ''Literature/TheReynardCycle'': Given how completely blind she is to the villainy of both [[spoiler: her cousin]], and later, [[spoiler: Reynard himself]], the Countess Persephone is an excellent example of this.
* ''Franchise/StarWarsExpandedUniverse'':
** Mara Jade is typically a decent judge of character, but not necessarily when it comes to the Emperor. In ''Literature/{{Allegiance}}'', while in his presence Mara thinks of him as a "wise and good man", for all that there are all kinds of little hints that she knows very well that he's not. She ''is'' an Emperor's Hand, a Force-Sensitive agent who can hear his commands from anywhere in the galaxy, and it's not hard to imagine that he messed with her head. [[Literature/TheThrawnTrilogy Five years after his death]], she's more angry at Luke for killing Palpatine because this destroyed her way of life and because his last command still echoes in her head. Not so much because a good man wisely leading the galaxy was killed, and in fact between the evidence and his waning influence she's rather messed up. In ''SurvivorsQuest'' she finds herself working with the [[BadassCrew Aurek Seven stormtroopers]] and gets a little nostalgic for the Empire until she goes into the storage core of ''Literature/OutboundFlight'' and sees all of these supplies stacked up, on Palpatine's order, for fifty thousand people he was arranging to kill.
** She wasn't exactly on the ball concerning Jacen either, although the level of her uncharacteristic obliviousness in that series seemed to vary from book to book, [[DependingOnTheWriter depending on what the author at the time needed in order to get away with the plot]].
* From ''Literature/HarryPotter'':
** Snape in regards to Harry. Snape views Harry as arrogant, attention-seeking, and selfish, whereas nothing could be further from the truth.
** Cornelius Fudge in regards to Lucius Malfoy.
** Percy Weasley - if calling ''Dolores Umbridge'' a "delightful woman" doesn't make him a Horrible Judge Of Character, it's hard to imagine what does.
** Everyone trusted Voldemort before his first rise to power. Everyone that is, except Dumbledore.
*** It probably helped that Tom Riddle was brilliant, good-looking, ridiculously good at charming people, and had the "sympathetic orphan" angle going. When he got to Hogwarts, he started to do his damnedest to make everyone think he was a good guy. The folks at the orphanage knew enough to be terrified of him.
*** Most of his followers tended to mistake a completely unhinged trigger-happy lunatic for a strong and visionary leader about to usher a new shiny era of pure-blood dominance for them to enjoy. Though really, the only ones who seem to believe this are as crazy as he is, like Bellatrix. Among the other major Death Eaters, [[DirtyCoward Wormtail]] just joined up because he was terrified, [[AristocratsAreEvil Lucius]] always advances his own interests first and foremost, [[PsychoForHire Greyback]] doesn't care about politics and simply likes a boss who'll let him kill things, and Snape [[spoiler: had a rather involved personal agenda]].
** The Sorting Hat is a good judge of character, but lets itself be swayed by students who have a strong preference for a house other than the one the Hat would have chosen. We see this expressly with Harry, but it's hinted with Snape (on the train to Hogwarts he expressed a strong preference for Slytherin, even though he had a lot of Gryffindor traits, to the point that Dumbledore wonders whether the Hat might have placed him differently if it were given the chance to reconsider). And it doesn't take too much WildMassGuessing to imagine the Hat also considered James Potter ([[JerkJock arrogant]] [[InsufferableGenius rulebreaking prodigy]] that he was as a youth) in Ravenclaw, but granted him his strong wish (also expressed on the train) to be in Gryffindor. (It's worth mentioning that while the Hat stood by its earlier opinion that Harry would have done admirably in Slytherin, Dumbledore disagreed completely in ''[[Literature/HarryPotterAndTheChamberOfSecrets The Chamber of Secrets]]'', claiming that only a student who [[BigGood Godric Gryffindor]] himself had favored could have drawn his sword out of the Hat.)
* Eddard Stark in ''Literature/ASongOfIceAndFire''.
** Sansa is this at first with regards to Joffrey and Cersei, but she eventually becomes disillusioned. Other than that, though, she's generally a pretty good judge of character--she's one of the few people who immediately recognized [[MagnificentBastard Littlefinger]] as being a dangerous creep--and this has only been improving as she acquires JadeColoredGlasses.
** Catelyn. She jumps to the conclusion that Tyrion is an untrustworthy moustache-twirler (granted, she's not the only one unable to see his heroic streak). She considers her sister to be bit flighty, but otherwise sound... until it gets rubbed in her face (nope: crazy lady be crazy). And, although she loves him, she considers her brother an airhead (he is, to an extent; but, mainly because he never gets full information). And, she considers Roose Bolton a dependable commander (up to a very sharp point, it's true; yes). She was the one who introduced Eddard to her "little brother figure", too.
** Basically, Littlefinger just seems to have this weird ability to nullify the negative in ''almost'' everyone's judgement of his character, [[MagnificentBastard and he knows it!]]
** Theon Greyjoy. No, Theon, this is not a helpful [[TheIgor Igor]]. This is [[MistakenForServant the master of said Igor]], who wants to give you a FateWorseThanDeath.
* Creator/DavidSedaris claims in one of his essays that [[SelfDeprecation all his closest friends are horrible judges of character]].
* At the start of ''Literature/TheCountOfMonteCristo'', the young Count himself is a terrible judge of characters, trusting as friends the same men who will completely ruin his life and get him started on the quest for revenge that will occupy the rest of the story. In fact, he will never realize, by himself, the reason of his downfall: only with the help of old Faria will he be able to finally get a clue.
* Cheryl from ''Literature/AtlasShrugged'' is a young woman who believes in her author's philosophy of hero-worshiping. As a member of the villainous faction of Looters, [[ManipulativeBastard James Taggart]] believes in a philosophy which is the exact opposite of Cheryl's. And yet, Cheryl manages to misunderstand Taggart so badly that she thinks he's a heroic man who believes in heroism, and marries him. [[LoveMartyr Naturally, the marriage goes badly for Cheryl]].
* In ''[[Literature/{{Dexter}} Darkly Dreaming Dexter]]'', Dexter [[LampshadeHanging comments]] on this quality in his co-workers, a trait that gets carried over to the TV series, as mentioned below:
-->'''Doakes''': ''[to Dexter]'' You give me the [[PrecisionFStrike fucking]] creeps.\\
'''Dexter''': ''[narrating]'' How is it that in a building full of cops, all with a supposedly keen insight into the human soul, is Doakes the only one who gets the fucking creeps from me?
* Literature/InDeath series: Peabody sure acted like this in ''Holiday In Death''. Eve had warned her that Brent Halloway was the wrong guy to get attracted to, due to his ItsAllAboutMe attitude. Peabody still got gooey-eyed over the guy, and as a result got his fingers being stuck into her crotch, and in one of Roarke's bars on a date, no less! At least Peabody gave that pervert a NoHoldsBarredBeatdown.
** [[spoiler:Eve's mother]] in ''New York to Dallas'' proves to be this. Both Eve and Melinda Jones try to warn her that Isaac [=McQueen=] is just using her and will kill her off like so many of his "partners". She doesn't listen. Guess what happens to her later on.
** Roarke in ''Innocent in Death'', believe it or not. Usually, he is anything except this trope. However, an old lover named Magdalana comes back and has him fooled. It took considerable effort on Eve and Summerset's part to get Roarke to see that Magdalana was just a BitchInSheepsClothing.
* Literature/SisterhoodSeries by Creator/FernMichaels: Bobby Harcourt in ''Sweet Revenge'' was apparently this with regards to Rosemary Hershey, according to Isabelle Flanders's recounting of past events. Fortunately for Bobby, the lust he felt for her wore off by then, he had come to see Rosemary for what she really was, and decided to divorce her. Roland Sullivan is ''Lethal Justice'' is very much this. He felt such lust for Arden Gillespie that he cheated on his wife, and essentially became Arden's puppet. Even when the consequences finally start hitting him, he refuses to leave Arden. He even figured out at a very late date that Arden had no conscience, and she confirmed it when he asked her. He still did not leave her. This just shows that Roland is a real piece of work!
* Mister Poe in ''Literature/ASeriesOfUnfortunateEvents'' has a tendency to fall for Olaf's PaperThinDisguise of the day that's part this, part CaptainOblivious, with maybe a dash of [[ApatheticCitizens not caring]].
** In general, whenever Poe expresses an opinion on someone or something, it's pretty much the opposite of what the Baudelaires (and by extension, the audience) are thinking. Though at times it can be unclear if it's this trope, or he's just trying to put on a brave face.
* In the Young Adult novel ''Literature/{{Rosebush}}'' by Michele Jaffe, this is a ''huge'' factor in the plot, as it's the protagonist Jane who doesn't know which of her friends is the one who tried to kill her.
* Senex in ''Literature/TheBookOfTheDunCow'' unwittingly makes a DealWithTheDevil with the evil Wyrm, never realizing who he is actually talking to until it's too late.
* Tash Arranda, a Force-Sensitive protagonist from ''Literature/GalaxyOfFear'', is very hit or miss when it comes to her friends. Thanks to their shared aptitude for TheForce, immediately after meeting [[TheHero Luke Skywalker]] she feels like [[StrangerSafety she can trust him]]. Similarly she's quickly able to sense that Wedge Antilles, Lando Calrissian, Fandomar Nadon, and Dash Rendar are good people. However, the Force ''doesn't'' give her DetectEvil powers unless the people in question [[TheForceIsStrongWithThisOne are also Force-Sensitive]], and she's quite susceptible to [[BitchInSheepsClothing friendliness and flattery]]. Her brother, remembering the times she's picked up on the people who are the most helpful, once assumes that anyone she likes will be similar and it backfires.
* The title character of Creator/JosephineTey's ''Miss Pym Disposes'' is an amateur psychologist (formerly a teacher of French, now a bestselling author), inclined to be proud of her work in psychology. She spends some days at a women's college and at the start reflects that she's never seen such fine specimens of English women. Well, not only do all sorts of not-so-fine things turn up, but the first woman she'd taken an instant liking to turns out to be a murderer. The book ends with Miss Pym reflecting bitterly that "as a psychologist she was a pretty good teacher of French" and vowing to stop lecturing on psychology.
* Mr. Boddy in the little-known ''TabletopGame/{{Clue}}'' book series is surprisingly never actually killed, but a lot of attempts are made on his life by the ''same six people he consistently invites over'' either to show off this new tomb he bought to put in the back garden complete with tour, have a nice dinner, afternoon tea... he even {{lampshades}} this. He always escapes, somehow, and talks about it in the next entry.
* George Denbrough, the first victim of the MonsterClown in Stephen King's ''Literature/{{IT}}''. Yes he's six years old, but you'd think he'd still sense something not right about a clown who suddenly appears in a sewer grate.
* Julia Valerian of ''Literature/TheMarkOfTheLion'' series is this in regards to her romantic relationships, consistently choosing partners who are [[DomesticAbuse abusive]], [[AllTakeAndNoGive invariably selfish]], or who don’t love her back and are merely playing her like a fiddle for their own ends, only to drop her when she is no longer of use. Given her romantic WideEyedIdealist nature in the beginning of the series and where this vicious cycle eventually [[RichesToRags lands]] [[TheDiseaseThatShallNotBeNamed her]], this is a little bit heartbreaking.
* Both the king and queen in ''Literature/KingdomOfLittleWounds'' place complete faith in people they really shouldn't trust. Both of their most trusted advisers are plotting against them.
* Played with in ''Literature/{{Divergent}}''. Four has no problem identifying Marcus as a bad person or Tris as strong or brave, but [[spoiler:becomes the UnwittingPawn to multiple characters in the series]]. In the cases of [[spoiler:Evelyn and Nita]], they try to make it up to him, however.
* ''Literature/{{Pharaoh}}'' - Ramesses is a bit of a loose cannon, but quite easily manipulated. Partially due to being so changeable.
* ''Literature/TheHungerGames'': One of Katniss's biggest flaws. Quite simply, she has a nasty habit of always assuming the worst of everyone she meets when these people ironically often end up saving her life and or genuinely caring about her. Her trust issues mostly stem from her childhood trauma of never having anyone to be there for her and in turn having to be there for her younger sister.

[[folder:Live-Action TV]]
* ''Series/{{Angel}}'': Two examples with Cordelia.
** When Harmony comes to town, Cordelia continues to trust her and demand that her friends give her a fair chance even after discovering she is a vampire, dismissing Angel's warnings that vampires are AlwaysChaoticEvil and can't be trusted. He's proven right when she sides with the vampire cult she was supposed to be helping A.I. investigate.
** Then, when Darla shows up pregnant with Angel's child, Cordelia readily defends her from Angel and tries to keep her comfortable, which comes back to bite her (literally) when Darla attacks her. After Angel comes in and saves her, Cordelia even acknowledges that she blew it.
* In HappyEndings, this is slightly inverted and played with-Jane states she has pretty solid "bitch-dar" and then quietly remarks to herself "You are not fooling me one-armed surfer girl."
* Liz Lemon of ''Series/30Rock'' has this in spades. There's her long list of horrible dates and trusting the wrong men. There's the fact she counts Jenna as a friend despite the fact the woman is a hopeless narcissist. There's continuing to fail to realize the depths of Tracy's stupidity and insanity until it causes trouble. And there's her failure to realize that yes, Jack really is that amazingly selfish and shallow sometimes.
** Most notably, Liz is a horrible judge of her ''own'' character. She talked in high school of being the picked-on nerd only to discover she was the horrible bully putting everyone down. For example, she constantly talked to a "friend" on his being gay and such but he saw it as horrible insults. When she says at the reunion she just wanted to give him the courage to come out, he asks "come out of what?" and introduces his wife.
* ''AllMyChildren'': Lily Montgomery. To be fair, Lily is autistic, but still, out of four crushes she's had in the last two years, two were murderers and a third was a pedophile. (The fourth was just really whiny; she dumped him for a murderer.)
* ''Series/TheBigBangTheory'': Penny. She's gotten better, but for the first two seasons, the list of how many jerks she fell for was pretty long. Penny knew they were jerks but just didn't care; it was only after dating Leonard that she couldn't put up with them anymore. She then blamed ''Leonard'' for this, accusing him of "ruining dumb guys" for her.
* ''Series/BuffyTheVampireSlayer'': Genevieve thinks that Roden actually cares for her.
* ''Series/{{Dexter}}'':
** Near ''everybody''. The title character works with a precinct full of police who don't notice that their co-worker is a serial killer. In his family, only his foster father caught on, and he already knew Dexter was traumatized. His sister not only misses his own craziness, but [[spoiler:gets engaged to the villain of season 1]].
** Even Dexter himself, while he constantly acknowledges that he's a monster, is way too willing to trust people like Trinity if he thinks he could learn something about coping from them.
* ''Series/DoctorWho'': The Tenth Doctor is unrelentingly idealistic towards his enemies, no matter how blatantly evil they are. This is especially true regarding the Master, whom the Doctor once said was beautiful and said he'd be honored if he were to travel with him ... this same guy who has tried to take over or destroy whole planets (or even the universe), not to mention trying to kill the Doctor in horrific fashion over and over again.
* ''Series/GossipGirl'': Serena van der Woodsen judges a person's character based on one very simple criteria: Whether or not they like Serena. If somebody claims to like her she is convinced they must be a genuine, nice person even if they've admitted to [[spoiler: purposely seducing her to con her mother and her mother's friends out of a lot of money]]. People she has previously hated, like Carter Baizen, are suddenly wonderful people once they show interest in Serena. This way of judging the world does come back to bite her in the rear on more than one occasion.
* ''Series/{{Heroes}}'':
** Dr. Mohinder Suresh possesses the uncanny ability to always somehow manage to make the absolutely worst possible choice in any given situation, a talent that has him repeatedly end up siding with and helping the bad guys (frequently without even realizing it). There's an [[EpilepticTrees increasingly popular Fan Wank]] that says this ability is his ''real'' Hero Power.
** Sandra Bennett gets a moment like this when first meeting Sylar. This a man who is creepy, with the eyes of a killer, made all the creepier when he adopts a southern accent. Even when he's being sweet he's still creepy. What does Sandra say to him? "Well, aren't you sweet!"
** Peter Petrelli also counts. He trusts almost everyone he shouldn't, whether it be [[ManipulativeBastard Nathan, Adam, his mother]], whoever. It's usually because he naively thinks people are good, but it gets a bit ridiculous.
** Maya may be worst of all, though: she is flat out ''told'' that Sylar killed his own mother, but continues roadtripping/making out with him anyway. Later, when she finds out Sylar has murdered her brother, she's completely shocked and devastated.
*** In her defense, he was the only person aside from her brother who treated her nicely since discovering her ability. And when he's called on it and admits it, he words that situation to appear that it was an accident, and makes no mention of the rest of the body count he's racked up. While it doesn't sound convincing to the audience, Sylar's good enough at lying for her to buy it as well as making his situation similar enough to her own. She does eventually wise up to his true intentions in "Powerless" after he threatens her.
* ''Series/ICarly'': Carly, Sam and Freddie all suffer from this, falling for or befriending jerky guys and manipulative girls.
* ''Series/{{Lost}}'': John Locke is so frequently blinded by his [[IJustWantToBeSpecial need to be special]] and needed that he ends up getting duped both off-island and on by [[DesperatelyLookingForAPurposeInLife anyone who tells him]] that he is important.
* ''Series/{{Merlin}}'': A genetic trait for Pendragons, apparently. Uther and Arthur are completely clueless that Morgana is plotting against them in season three, despite the fact that [[TraitorShot sinister smirking]] has become her default facial expression. Happens to Arthur again in season four when his uncle Agravaine becomes his most trusted adviser, despite the fact that Agravaine is VERY ObviouslyEvil.
* ''Series/{{NCIS}}'': Kate suffered from this to an extent; it only happened a few times, but it is especially notable in her case both because it was the negative side of her trusting nature, and because it was probably her FatalFlaw. [[spoiler:Since she was unable to shoot the man who would later kill her because of his 'kind eyes']].
* ''Series/TheOC'': Marissa, in the Oliver story-line of Season One. Her later dalliance with [[spoiler: Volchok]] doesn't count because she is fully aware he is bad for her. She is aware that he is "bad" by most people's standards, but actively defends him as misunderstood to everyone, until [[spoiler:he cheats on her, humiliates her and uses her to steal money]].
* ''Series/TheOfficeUS'': Michael Scott has two means of judging a person's character: by their appearance, [=and/or=] their willingness to be his friend (or even have lunch with him).
* ''Series/PowerRangersOperationOverdrive'': Norg the Yeti. One of the bad guys barges in and takes over his arctic home, and Norg is just so happy to meet a new friend and would you like a snow cone? This dynamic lasts all season until the villain finally orders his {{Mooks}} to "take care of" both Norg and a DistressedDamsel - said damsel has to spell out the TroubleEntendre to Norg before he gets it.
* In the ''VideoGame/MegaMan1'' episode of ''Series/RetroGameMaster'', Arino says that Dr. Wily seems like a nice guy.
* ''Series/{{Smallville}}'': [[CreatorsPet Lana Lang]]. Even the usually GenreSavvy Chloe Sullivan does this on occasion towards [[spoiler:Ian and Davis Bloome]]. Maybe LoveMakesYouDumb.
* [[Series/{{White Collar}} Neal Caffrey]], so much so. He prides himself on being good with people, and for the most part, he ''is'', but sometimes he makes really stupid decisions about who he should trust. This is the man who [[spoiler:fell for the woman he conned, lied to her in order to get information, told her the truth, entered a serious relationship with her, and worked with her to find a legendary diamond, only to find out that she had been playing him the entire time]].
-->'''Mozzie:''' You, women, and business do not mix well!
* ''YoungDracula'': In one episode, a friend of Vlad's grows into a full vampire and undergoes a FaceHeelTurn that causes Count Dracula to say EvenEvilHasStandards. Vlad is completely oblivious to this, even after an [[EvilGloating Evil Monologue]] or two. He has his reasons, since he's very worried about turning evil when he becomes a full vampire, and desperately wanted to believe that his friend had gone through the transformation without any personality change.
* Sharona in ''Series/{{Monk}}'', to the point where she willfully ignores evidence of the person in question's bad character. In the first episode alone, she went on a date with a guy who was pretending to be a lawyer, until Monk deduced that he was lying, ''and she got mad at Monk''.
* [[FoolishSiblingResponsibleSibling Real and Chance's]] mother during ''every'' appearance on VH1's Celebreality series to the extent that you'd lose a liver in a drinking game over it. Liked "[[SassyBlackWoman New]] [[TheDreaded York]]" because she was [[DistractedByTheSexy pretty]], liked [[AloofAlly Rabbit]] because she was [[PuritySue Christian]], [[RightForTheWrongReasons was wary of]] [[MrsRobinson MILF]] ''not'' because she [[DysfunctionJunction had a laundry list of emotional baggage she'd bring into a new relationship]], but because she was [[WhereDaWhiteWomenAt White... until finding out she has a half-Black son]]. About the ''only'' good advice she ever gave during her TV time was [[BrosBeforeHoes warning her sons not to let a woman come between them]].

[[folder:Myths & Religion]]
* From Myth/GreekMythology, Aphrodite. Seriously, her husband Hephaestus may not have been a prize catch, but falling for Ares, the homicidal god of war? The fact that she was likely the ''only'' one who even ''liked'' him should have tipped her off that he was bad news. She ''really'' could have done better. Though depending on the myth, Aphrodite [[BitchInSheepsClothing might not be any better than Ares]]. AllGirlsWantBadBoys, plus "All's fair in ''love'' and ''war''."
* Another example would be most of the city of Troy; it was pretty obvious that the Trojan Horse was a trap. In fact, some residents of the city were ''not'' fooled. Possibly the dissenter who could have had the best chance of making them reconsider was the Trojan priest Laocoön (the phrase, "I fear Greeks, even those bringing gifts" can be attributed to him), but after he and his sons were attacked and strangled by serpents, the Trojans paid his warning no heed. (Depending on the version, the serpents were sent either by Poseidon or Apollo, who both held grudges against Laocoön.) Helen also guessed the plot, and tried to expose it by mimicking the voices of the wives of some Greeks she suspected were inside the device to convince them to come out. (And Anticlus almost fell for it; the plan would have failed if Odysseus had not covered his mouth with his hand.) King Priam's daughter Cassandra, the soothsayer of Troy (the TropeNamer for CassandraTruth) predicted the Horse would be the doom of the city and its royal family. But all these warnings went ignored.

[[folder:Tabletop Games]]
* In TabletopGame/{{Warhammer 40000}}, arguably, The Emperor of Mankind counts as this. Despite numerous warnings from various sources, he still failed to see Horus' betrayal coming. I guess you don't expect that sort of thing from your favourite genetically engineered son...
** His trust in some of his other sons who turned to chaos and all the Chaos Space Marines who were, putting it lightly, horrible, horrible people.
** The one son he did decide not to trust, [[TheCassandra Magnus the Red]], was the one who tried to warn him about Horus, and who was pushed to Chaos as a result.
** The Horus Heresy was mostly caused by the Primarchs being miserable judges of character. The loyal Primarchs refused to believe their brothers would betray the Emperor, allowing them to be blind sided. The Traitor Primarchs that started the Heresy believed the Emperor was a power hungry jerk that was betraying them. In reality, while the Emperor was undoubtedly a jerk, his goal was ultimately pure - a golden age for Mankind, not the God-Emperor of Mankind.
** There are some stupid, ''[[TooDumbToLive stupid]]'' Imperial nobles who hire [[AxCrazy Dark]] [[AlwaysChaoticEvil Eldar]] to act as mercenaries, and as a deniable asset. Said Dark Eldar usually go in, kill/torture/enslave/unspeakable act their unfortunate victims, get paid, and then turn on their stupid, ''stupid'' employer. What's funnier is the Tau fell victim to this as well; they got Dark Eldar assistance during a particularly ruthless Tyranid invasion. Of course, the Dark Eldar were manipulating them and taking advantage of them right from the very beginning, and the clueless greyskins only clued in when they realized that the the "cultural exchange" party they sent over to meet them never returned, and some of the Dark Eldar's nightmarish flesh-hulk creations had a very familiar grey skin tone...
* There's also every Elven Noble thousands of years ago, from WarhammerFantasy. Not only electing Bel-Shanaar as Phoenix King, but also being blind to Malekith's evil intent for so long. Come on! [[MeaningfulName His name is MALEKITH!]]

* Creon in Creator/{{Sophocles}}'s Theatre/{{Antigone}}. Basically, every single character he meets, he utterly fails to spot that they have good reasons for acting the way they do, and wastes an inordinate amount of time accusing people of being selfish, corrupt or (in the case of Antigone herself) just plain female.
* Frequent in Creator/WilliamShakespeare's works.
** King Duncan from ''Theatre/{{Macbeth}}'' is the AnthropomorphicPersonification of this trope, as he blindly trusts both the traitorous Thane of Cawdor and his replacement Macbeth, who [[TooDumbToLive kills him]].
*** That isn't fair, yeah it's obvious to us who've had Shakespeare's lovely foreshadowing. But for Duncan he was just going to hang out with the guy who just helped save his kingdom. Without knowledge from the witches there was no reason to assume that Macbeth was going to murder him. (Why Banquo didn't do anything is another question.)
*** Ol' Shakespeare had to tread lightly with his characterization of Banquo, as the historical figure he's based on happens to be an ancestor of the King of England at the time.
** In ''Theatre/{{Othello}}'', Othello is mindlessly trusting of his ancient, "honest Iago," a character thoroughly devoted to ruining his life. To be fair to Othello, Iago has evidently been playing the loyal compatriot for years beforehand, and his deceptions show us he's ''really good'' at convincing people he's a trustworthy guy. This is more due to Iago being a ManipulativeBastard than Othello being a Horrible Judge Of Character.
*** That still doesn't excuse some of Othello's idiocy, such as saying he refuses to believe Iago's words about Desdemona's infidelity and then, two seconds later, believing what Iago says. Othello also refuses to believe people who ''are'' honest with him, such as Desdemona and Emelia.
** This was also ''Theatre/KingLear'''s problem when he was unable to distinguish between the genuine love his daughter Cordelia had for him and the shallow flattery offered by her wicked sisters.
*** More to the point, Lear failed to understand that carving up his kingdom according to how much his daughters claimed to love him, meant that the ones who came off best would simply be the ones who could most convincingly fake their love for him. He also failed to see that giving away all his land and power to his daughters was incompatible with wanting them to treat him as though he still had it.
** Also in ''{{Hamlet}}'' everyone but the titular character is too sycophantic and unintelligent to see that their new king Claudius is a usurper of the throne.
*** AlternativeCharacterInterpretation suggests that they might not want to anger ''the King of bloody Denmark'', since he can always just order their execution if he likes. The Queen, though, really should have known better - [[ThePlan unless she also knew about Hamlet's uncertain character and she was trying to keep her son from the throne, at least until he was ready]].
*** Also it is implied that the kingship is elective (Claudius "stepped in between the election and my hopes," Hamlet says); without knowing that Claudius murdered his brother, the electing nobles might have felt justified in choosing the older and more experienced Claudius over the young Hamlet.
* Siegfried in ''Theatre/DerRingDesNibelungen'', which proves to be his FatalFlaw. ''Everybody'' around him lies to him and uses him to their advantage, and this leads to his tragic and ignoble death.
* Played with in ''Theatre/TheImportanceOfBeingEarnest'': Cecily claims that her "first impressions of people are never wrong" when really they are ''consistently'' wrong.

[[folder:Video Games]]
* Seere in ''{{Drakengard}}'' (a small child) willfully invites himself into a party consisting of a child-killer, a child molester, and a child eater. He's got a stone golem to protect him, but ''still''.
* Luke fon Fabre from ''VideoGame/TalesOfTheAbyss'', the poor bastard. Trusting [[spoiler:his mentor Van]] has severe consequences when, [[spoiler:following his plan that will supposedly cleanse Akzeriuth of the miasma actually ends up destroying the city and advancing Van's plans]]. Though his trusting nature and idolization of Van comes about from his ''extremely'' sheltered upbringing and his [[YoungerThanTheyLook overall]] [[CloningBlues many other issues]].
* Proving that {{Evil Overlord}}s, too, can fall prey, Emperor Gestahl of ''VideoGame/FinalFantasyVI'' gets stabbed in the back by two out of three of his most trusted subordinates, with Celes doing s HeelFaceTurn and Kefka out-and-out murdering him before going into full-on OmnicidalManiac mode. On the flipside, the third subordinate, General Leo, falls under this as well, as he actually ''trusts'' Emperor Gestahl despite his mad plans for world domination and the enslavement of the Espers used for magicite research as well as the mind-controlling of Terra...he still believes him right up until Gestahl decides [[YouHaveOutlivedYourUsefulness he's outlived his purpose]] and has Kefka wipe him out. There's a lot of it to go around.
* ''VideoGame/NeverwinterNights'': Fenthick's horrible judgment and political ineptness in trusting Desther conspire to get him executed at the end of the first chapter of the main campaign. [[spoiler:It's okay, as his only reason for existing in the first place was to give Aribeth something to angst about before her FaceHeelTurn]].
* Lucrecia in ''VideoGame/FinalFantasyVII'' had a romantic relationship with Hojo, who could not be more of an evil depraved MadScientist if he tried. It's even worse that ''DirgeOfCerberus'' shows that he makes ''no effort'' to disguise what an awful person he is even right from the start. "Ah, so you have come to your senses and chosen me." [[spoiler:The reason she didn't choose Vincent was her lingering guilt over her part in his father's accidental death. Starting a relationship with Hojo was her way of ''punishing'' herself]].
* Where to begin on ''VideoGame/{{Fallout 3}}''? Well, how did Simms not see the evil in Burke? I mean, between the voice, the suit, and just the plain weirdness of him, Simms must have had brain damage! Oh, and Eden sounds so nice. Clue 1 that he's evil. And [[spoiler:a machine]]. Also, Roy Phillips, with you, Tenpenny, and everyone else being the bad judges, and Burke again, with Tenpenny being the bad judge.
** Clue 1 that Eden was evil wasn't that he sounded nice. It was that he's voiced by Malcolm [=McDowell=].
** In Burke's case, I guess that Simms was easily fooled, but Tenpenny is so senile and barely grasping reality, that would anyone really expect him to see a difference between a polite well-dressed gentleman and a [[AffablyEvil polite]], [[BadassInANiceSuit well-dressed]] evil assassin?
*** And it does seem unusual that the Lone Wanderer gains Karma from killing Tenpenny...
** Caesar from New Vegas is one for the player. Even if the Courier had good karma, was an NCR loyalist, and had killed hundreds of Caesar's mean, Caesar will still try to earn your assistance, invite you to his fort, and put some trust in your actions.
* Otacon of ''VideoGame/MetalGearSolid'' is shown to be attracted to the murderous Sniper Wolf, whom he claims is really a nice person [[YouFailLogicForever since she likes dogs]]. Snake actually lampshades this by claiming that Otacon has StockholmSyndrome (hostage attraction to one's captors).
* Mori Ranmaru in ''VideoGame/SengokuBasara'' is a kid who knows nothing except that UsefulNotes/OdaNobunaga is the coolest guy ever. And let's see what Nobunaga's portfolio contains... CardCarryingVillain, ObviouslyEvil, EvilOverlord, TakeOverTheWorld? Er... kid? You may want to reconsider --
-->'''Ranmaru''': How dare you in insult Nobunaga-sama! [[ThirdPersonPerson Ranmaru]]'ll kill you!
** To be fair, Nobunaga does seem to actually like the kid. He makes it a point to reward Ranmaru with candy and he does get angry if the player kills him.
** Motochika Chosokabe is another example in the third game. In Motonari's blue path, Motochika believes that Ieyasu was the man behind the attack on Shikoku. And THIS is despite that they were on friendly terms. He also thinks that Motonari and Mitsunari are on good terms with each other, which leads to his surprise reaction to Mitsunari's death by Motonari's hand. When Motonari confronts Motochika, he lampshades the latter's terrible judge of character in his [[TheReasonYouSuckSpeech speech]] to him.
* Dr. Light from ''VideoGame/MegaManClassic'' seems curiously willing to trust Dr. Wily when he claims to have gone straight (''[[VideoGame/MegaMan3 3]]''), to have his lab ransacked by a renegade robot (''VideoGame/MegaManAndBass''), or to be searching for the cure to a mysterious robot virus (''[[VideoGame/MegaMan10 10]]'').
** Arguably justified, as Light has been skeptical of Wily before (particularly in ''10'', when Mega Man expresses disbelief that Wily is being the good guy, Light wholeheartedly agrees with Mega Man's plan to investigate the Wily connection behind Wily's back), but, in defense of Wily's plan, he actually ''did'' have a cure for the robot virus (which it is implied he did ''not'' create), he was just planning on charging obscene amounts of cash for it.
* Although it's not a theme throughout the whole series, in ''VideoGame/MegaManBattleNetwork 6'' Lan shows an incredible ineptitude at differentiating friend and foe. He looks up to and almost idolizes [[spoiler:''two'' members of the quirky miniboss]], and is indifferent to a third, only correctly identifying one villain before he strikes for the entire game (and that villain is the one who thinks it is shameful to try to hide your villainy and chastises the others for being discreet). He also only learns that [[spoiler:the mayor]] is a villain by walking in on a conversation while going to ask him for help. Meanwhile, he is instantly suspicious of two figures who turn out to be [[spoiler:Chaud and Protoman, his longtime allies throughout the entire series]], nor does he connect the two even after the first reveals himself. The writers never seem to notice this trend.
* Chatot from ''VideoGame/PokemonMysteryDungeon'' has a major problem with this. When he ''finally'' learns that the TerribleTrio he's repeatedly lauded as some of the finest Pokemon he's ever had the privilege of working with are actually -- {{GASP}}! -- ''evil'', he does ''not'' take it well.
** It's worth noting that the first clue he gets that [[NamesToRunAwayFromReallyFast Team Skull]] aren't the exemplar of Pokemon-hood he thought they were is when they start sounding less refined. In the original Japanese, this would mean that they had just downshifted their speech to a less respectful level. In other words, all they had to do to gull Chatot was ''use the {{Keigo}} he assumed he merited''. He was taken in by his own overblown self-image!
* Prince Pelleas from ''Franchise/FireEmblem: [[VideoGame/FireEmblemTellius Radiant Dawn]]'' sees absolutely no problems with trusting Izuka to be his primary strategist. Izuka, for the record, is a stunted, cackling, yellow-eyed little troll of a man who invented a drug that turns people outside of his race into rampaging psychopaths for use as pawns in battle and ''openly brags about this invention''. And to top things off, he's not even a very good strategist! It should come as no surprise that this inexplicable trust comes back to bite Pelleas's entire ''country'' in a big way as the game progresses.
** Astrid from the same game, who sees [[TheSlacker Makalov]] as a KnightInShiningArmor.
** On the villainous side we have Levail, a young, idealistic general who believes that General Zelgius [[spoiler:(aka the BlackKnight)]] is "[[KnightInShiningArmor the last true knight]]" and plans to [[MyMasterRightOrWrong die for him]]. Now, Zelgius is undoubtedly [[EvilIsCool cool]]. However, he is also a crazed BloodKnight who brutally cut down his teacher just to see if he had surpassed him, and is currently TheDragon to [[spoiler:Sephiran]] a MisanthropeSupreme who plans to [[TakenForGranite turn the entire world to stone]]. His definition of "true knight" must be rather different from normal standards.
* Terra from ''VideoGame/KingdomHeartsBirthBySleep''.The same way some blind people keep a seeing-eye dog to make walking around safe, Terra should really be keeping an EvilDetectingDog around to make heroics safe, because there's being bad at noticing bad guys, and then there's ''needing someone to order you to kill an innocent'' to realize they don't have your best interests at heart. NamesToRunAwayFromReallyFast, ObviouslyEvil appearance with horns, flames, GlowingEyesOfDoom; temptations to TheDarkSide... it all swooshes right over his head as he assumes them to be perfectly nice people.
** All of the main cast fall under this with regards to Master Xehanort. The guy is one of the most obvious villains around, and without the benefit of sitting behind the fourth wall the cast should be able to at least ''guess'' that Xehanort's BaldOfEvil, gold eyes (a sign ''in series'' that someone has been taken by the darkness), BeardOfEvil, SlouchOfVillainy, the SpikesOfVillainy adorning his Keyblade (which is a frakking battle ax) and nearly constant PsychoticSmirk are signs he's not all love and rainbows. Even the character who has been physically wounded by Xehanort using the darkness in the past shows absolutely no signs of worry that he might be up to no good (a lot of the game's problems could have been avoided if he had just given them a heads-up). And yet everyone acts surprised when it's revealed that he's actually the bad guy.
** This seems somewhat justified. The heroes' experiences make them out to be severely unknowledgeable about the outside world, and being trainees they were probably not even allowed to leave the Land of Departure without Eraqus's discretion. Since they could trust each other and they were the only people they knew, they never went outside thinking people could be deceptive.
** Riku in the first game following [[ObviouslyEvil Maleficent]] and believing her words that Sora is unworthy for daring to help other people in his journey to find Kairi, and that Maleficent would let him rescue Kairi and leave.
* Knuckles the Echidna from the ''Franchise/SonicTheHedgehog'' series is so gullible that it's become a joke both in the fandom and in the series itself. He's such a bad judge of character that, even though he's been fully aware for ''years'' that Dr. Robotnik doesn't say anything that won't get him closer to the Chaos Emeralds and world domination, he still takes everything the corpulent madman says at face value, and follows up on things Eggman says better than things that people he ''trusts with his own life'' tell him. The other characters have been riding him about it for years; if he does something even subjectively stupid, the knee-jerk assumption is that he's been talking to Eggman again. To be fair, Knuckles only falls for Eggman's tricks once a series. ''[[VideoGame/Sonic3AndKnuckles Sonic The Hedgehog 3]]'' was the only time Knuckles completely believed him since it was their first meeting. In ''VideoGame/SonicAdventure'' Eggman only makes Knuckles confused and suspicious about Sonic's actions (and considering the Master Emerald was destroyed, Knuckles probably wasn't in the best frame of mind at the time). ''Anime/SonicX'' Eggman plays on Knuckles's rivalry with Sonic, and again Knuckles isn't in the best frame of mind, being pissed that he's stuck on Earth.
** He was implied to have been tricked completely one other time: In ''[[VideoGame/SonicAdvanceTrilogy Sonic Advance 2]]'', Knuckles ends up being tricked somehow by Eggman into fighting Sonic with the Egg Saucer, which, after Sonic destroys it, Knuckles chased him covered in soot. The cutscene afterwards reveals that he was tricked by Eggman once again, with Knuckles being upset at this revelation, and Sonic deciding to leave him to sulk until Knuckles decides to get his act together.
* ''The Urbz: Sims in the City'' has a minor character, Lily Gates, who apparently means well but is a terrible judge of character.
* According to Nathan Drake of ''VideoGame/{{Uncharted}}'', Sully is this when it comes to women.
* ''VideoGame/InThe1stDegree'': Poor Zachary Barnes. He truly believed that James Tobin was a good guy, despite him making mistakes. Too bad he didn't realize until he got shot in the throat that his business partner was a greedy, jealous {{Jerkass}} with no redeeming qualities, who had threatened Barnes with bodily harm several times and had threatened to kill him a week before the murder.
* Conrad Marburg from ''VideoGame/AlphaProtocol'' is apparently so bad at judging character that his dossier feels justified in devoting a paragraph to it. His boss, Leland, also mentions it. In-game, it takes a very short time to learn how to manipulate Marburg, as he responds consistently positive to one attitude and consistently negative to the other two.
* ''VideoGame/RedDeadRedemption'' has Luisa Fortuna, a relatively bright but naive Mexican peasant girl who is a fanatical follower of local RebelLeader Abraham Reyes. In her eyes, Reyes fights for the people and loves her just as she loves him. In the eyes of John Marston and the player however, Reyes is an egomaniac with a talent for getting peasants to listen to him whose only concern is personal glory and can barely remember Luisa's name. Similarly, Luisa has problems seeing that John [[NotInThisForYourRevolution cares nothing for the fate of Mexico]] and helps her and the rebels only because he's got a soft spot for her and that they're a means to an end.
** Marston himself in most of the side missions.
* The player character in ''VideoGame/WorldOfWarcraft'' will accept quests from ''anyone'' with shiny punctuation over their head, including crazy, skeevy-looking old men hiding in a shack in the haunted, zombie-infested woods, with mysterious bloodstains all over the shack and a pile of cadaver innards out back. And then the player's all ''surprised'' when the old man unleashes onto the town the abomination that you helped him build.
** Normally, we'd say that Player Characters [[TheyJustDidntCare just don't care]], but given that you have to fight Stitches at the end of the questline, you unquestionably made it worse for yourself there.
** This is Thrall's biggest character flaw. [[TheNecromancer Sylvanas]], [[BadBoss Gallywix]], and [[UtopiaJustifiesTheMeans Garrosh]] have all joined the Horde because of him. While Gallywix hasn't done anything post-joining (though he was pretty awful beforehand), Sylvanas and the Forsaken have developed biological warfare and disgust everyone else by raising undead, and Garrosh was a raging patriot and warmonger, [[SuddenSequelHeelSyndrome who in the Pandaria expansion turned into]] a EvilOverlord.
* ''VideoGame/JadeEmpire'' can play it straight or put an unusual twist on it. A surprising amount of people seem to think that the impeccably polite young warrior who radiates unearthly calm and has a halo of heavenly light around their head is the ''perfect'' person to approach with offers of criminal collaboration.
* ''VideoGame/JakIIRenegade'' we find that Keira has a crush on Erol, Commander of the Krimzon Guard and the man who [[ColdBloodedTorture tortured]] Jak for two years with Dark Eco experiments. When informed that he's a bad person, she refuses to believe it.
* In ''VideoGame/ShinSuperRobotWars'', Shakti explains that she was in the Angel Halo because she had to be put into the machine in place of her mother the queen. Londo Bell fills her in on how Char deceived her into thinking she could stop the fighting and put her mother at ease. Amuro kindly tells her that she needs not apologize for cooperating with an apparatus intended to brainwash mankind - it's all Char's fault for leading her into it.
* In ''VideoGame/DragonAgeOrigins'', Bryce Cousland considers Rendon Howe to be his best friend. ''Nearly everybody else'' in Ferelden thinks Rendon's a terrible human being, and they are right. Bryce's misplaced trust in Howe gets him and his entire family (except for the Human Noble Warden if that origin is chosen) killed.
* ''VideoGame/{{Grand Theft Auto V}}'': Lamar according to Franklin. Franklin calls him out on this and mentions that he's always had to bail Lamar out of trouble for as long as he's known him [[SlidingScaleOfGameplayAndStoryIntegration (Sometimes when switching to Franklin, you see him stop a fight between Lamar and someone else)]]. Reaches TooDumbToLive levels when after [[spoiler: Franklin travels all the way to Blaine County to save him from Stretch's plan to kill Lamar, Franklin pulls a SherlockScan on Lamar explaining the entire situation with Lamar happily holding the IdiotBall, still believing that Stretch is "His nigga" much to Franklin's anger and exasperation]].
* ''Videogame/PokemonXAndY'' has Professor Sycamore, who after listening to Lysandre's speech of [[ObviouslyEvil how the world must be cleansed of what he considers filth]] praises the man for his passion. Subverted in that he later admits that he had an idea on how far Lysandre would go, but was never able to confront him about it, making his earlier praise look more like denial than being oblivious.
* ''[[VideoGame/{{Touhou}} Double Dealing Character]]'' starts when Shinmyoumaru Sukuna heeds her friend Seija Kijin's plan to place the weak on top of the strong. The fact Shinmyoumaru decided to trust Seija ''knowing full well'' she's a {{youkai}} belonging to a species of chronic liars and scammers should tell you all you know about her.
* Prior to the start of ''VideoGame/SuperRobotWarsBX'', [[Anime/MacrossFrontier Ranka Lee]] falls out of an airlock off-screen and is magically rescued by the Vagans, even though this takes place in outer space (the [[Anime/MacrossFrontier Battle Frontier]] is on [[Anime/PanzerWorldGalient Arst]]). Ranka essentially becomes a Vagan sympathizer for having been rescued by them.

[[folder:Visual Novels]]
* From the ''Franchise/AceAttorney'' series:
** Will Powers from the first two games has trouble believing who the real culprit is in both cases 1-3 and 2-4, because [[spoiler:they are people he trusted as coworkers]]. He's not very good at seeing the bad in people.
** Iris from ''Phoenix Wright: Trials and Tribulations'' is thought of this way by Edgeworth after she calls Maya 'strong and reliable' and Larry 'sincere and hard-working'; however, they can be described as these under certain circumstances. She ''also'' trusts [[spoiler:her murderous twin sister Dahlia despite the numerous examples of Dahlia abusing this]].
* ''VisualNovel/FateStayNight'': Hi I am Kirei Kotomine. I am emotionless except when amused by the discomfort of others. I'm a jerk, I make fun of you, and I act really suspiciously. Yet everyone just seems to believe that he has nothing to do with what's going on, except Tohsaka. Even she just knows that he's not a nice guy. In "Heaven's Feel" up until the end Shirou doesn't really think of him as an enemy where he's quite blatant about not being on Shirou's side or even neutral ''or'' pretending he doesn't have a hidden agenda having to do with widescale destruction.
** By that point in "Heaven's Feel", Shirou just doesn't ''care''. Kotomine is on his side for that battle, and he needs him to help [[spoiler:save Sakura and Ilya]]. That's all that matters.
** Poor, poor dear Bazett...
* In HatePlus the Councillor of Security Old *Mute completely underestimates the danger [[spoiler: Councillor Ryu]] poses, considering him a mere pawn and believing the real threat to security to be the peasantry. Justified in that he only became dangerous as a result of his contact with and due to the influence of [[spoiler: of Oh Eun-a]], something Old *Mute wasn't aware of.
* A more lighthearted variant of this trope appears in ''VisualNovel/SuperDanganRonpa2'' when the students are discussing why Byakuya dove under the table. Keep in mind that Byakuya is far from being the ''{{class clown}}''.
-->'''Akane''': Obviously he was hidin' so he could surprise us. That dude was always a big jokester.
-->'''Kazuichi''': The hell he was! You seriously couldn't tell what kinda person he was!?

* Fighter from ''Webcomic/EightBitTheater'' insists that AxCrazy Black Mage is his "bestest [sic] friend" and will protect the SquishyWizard against attacks from others, despite the fact that Black Mage hates Fighter's guts, and has said so, and has repeatedly tried to kill Fighter (not that it works, because Fighter is [[MadeOfIron practically]] [[ContractualImmortality indestructible]]). Fighter, being the {{Cloudcuckoolander}} that he is, will insist that this is merely Black Mage being "[[VitriolicBestBuds such a kidder]]."
* In ''Videogame/{{Earthbound}}'' webcomic ''Webcomic/TheChosenFour'', Monotoli describes Pokey like "such a nice boy, but a bit troubled". Seriously. It is not a wonder Pokey was able to exploit him.
* Gordon Frohman of ''Webcomic/{{Concerned}}'' is a BlackShirt who utterly supports The Combine who have enslaved his race and is utterly against LaResistance of the humans, Gordon Freeman as well as the Vortigaunts, the alien allies of the humans. [[spoiler:His hatred of Vortigaunts ends up making them choose to let him die rather than save his life]].
* [[Webcomic/ScaryGoRound Ryan Beckwith]] is way too trusting for his own good when it comes to Ralph, Tackleford's local occultist. Even though Ralph's advice has come back to bite him in the ass time after time, he still defends him and goes back to get his spiritual advice. This may have changed now that Ralph has [[spoiler:been exposed as [[LouisCypher the devil]]]].
* Joey from ''[[http://www.agameoffools.com A Game of Fools]]'', who doesn't seem to realise that the aliens that have abducted him mean to kill and rape him, can't see anything weird about an [[http://www.agameoffools.com/comic_32.html insane naked man whose "backpack smelt like dead people"]] and thinks the AxCrazy hitchhiker they've picked up, who openly admits to multiple murders, bizarre sexual fetishes and [[http://www.agameoffools.com/comic_34.html necrophilia]], is a perfectly nice guy.
** There's also the fact that he still considers [[ManipulativeBastard Sylvester]] one of his best friends despite the [[http://www.agameoffools.com/comic_48.html absolutely]] [[http://www.agameoffools.com/comic_95.html goddamn]] [[http://agameoffools.com/comic_144.html horrible]] things he manipulates him into doing.
*** Sylvester can be pretty bad himself, particular when it comes to his friendship with Tomato (and the majority of his other friends too, if [[http://agameoffools.com/comic_75.html this]] is any indication). Although in his case he does at least seem partly aware how horrible they are - he just doesn't really care.
** Joey's [[http://agameoffools.com/comic_42.html rather poor]] [[http://agameoffools.com/comic_169.html choice of gym]] probably counts too.
* Otacon comes up again in ''Webcomic/TheLastDaysOfFOXHOUND'', where Liquid is able to convince him to install a nuclear launch program on Metal Gear by telling him that he wants to shoot down meteors like in ''Film/{{Armageddon}}'' (however, there's evidence that Otacon's in denial about Metal Gear's true purpose at this point, and Liquid did threaten to feed him to a largely-unfriendly-to-him-wolf).
* In ''Webcomic/TheOrderOfTheStick'':
** Poor, deluded Tsukiko. Do you honestly think that just because you think the living are jerks, the undead CardCarryingVillain Xykon is going to be any better? Even the Monster In The Darkness has worked this one out. [[spoiler:This ultimately proves to be her downfall when her beloved Wights turn against her when Redcloak uses Command Undead on them, with her last words asking why they won't love her as she loves them]].
** For that matter, the Monster in the Darkness himself is convinced that Xykon and Redcloak are his friends because they give him food and toys to shut him up. Somewhat more justified in his case, though, as he has a rather childlike personality. And after finding a ''real'' friend in O-Chul, he might be growing out of it.
** Ian Starshine has so far concluded that ChaoticGood Elan is evil to the core because of his father, but ChaoticEvil Belkar has some good in him. While his assessment of Elan is completely off the mark, his assessment of Belkar is a bit more reasonable, as Belkar had recently learned the value of actively deceiving others that he was good, or at least willing to play along with society's rules. However, this is exactly the kind of deception a master thief should be aware of, so it still counts. May also be [[spoiler:foreshadowing as Belkar's development seems to be turning genuine]].
** Elan himself displays this behavior towards [[spoiler:his father, General Tarquin]] when they first meet, being so desperate to see him as [[spoiler:the father figure he's always wanted]] that he overlooks the fact that he's a scheming LawfulEvil general and one of the key players in an oppressive dictatorial empire.
** Celia has a tendency to trust people who really don't deserve to be trusted, such as in "[[http://www.giantitp.com/comics/oots0574.html A Seller's Market]]," when she puts her faith in a thug despite knowing that he murdered his own brother, (wrongfully assuming that he's wracked by guilt over the incident), and in "[[http://www.giantitp.com/comics/oots0648.html A Dish Best Served with +1D6 Cold Damage]]," when she's lied to by Haley and accepts the lie without question.
** Zig-zagged when one of the party members is brainwashed and vampirized: Belkar is ProperlyParanoid about Vampire Guy deceiving everyone for his own purposes and the rational discrepancies, while Roy opposes this due to his knowledge of Pre-Vampire Guy and his current streak of acceptable actions. Roy's anger reaches a breaking point when he realizes just how stupid he was about the ObviouslyEvil guy (and is STILL unaware of his true identity).
* Kiki towards Bun-Bun in ''Webcomic/SluggyFreelance''. She acknowledges him as being a little mean and grumpy, but thinks all he needs to get over that is more hugs.
** Riff is certain Sam the vampire and Aylee the alien are threats to humanity, even after years of contradicting evidence. But he'd never suspect his girlfriends of sinister agendas, not 'too cool to be true' Sasha or 'Psycho Girlfriend From Hell' Monica. And he knows for sure that his father is not "a bad guy."
* Hanna in ''Webcomic/HannaIsNotABoysName''. Sure, you can make deals with vampires. [[SarcasmMode They're trustworthy and never go back on their word; even when you're trusting them with your life and everyone else's]].
** Lee Falun. His best friend was a {{Jerkass}} whose son was always [[AbusiveParents covered in bruises]] and whose wife plainly resented him. Did Lee do the math? Nope. Said best friend also murdered him.
* In ''Webcomic/BobAndGeorge'', Dr. Light has problems with this in the ''Mega Man 3'' story arc, completely ignoring every obvious sign that Wily doesn't have the amnesia he claims to have, taking the problem in the actual game and turning it way, way UpToEleven. Then subverts it at the end when it is revealed he deliberately gave Dr. Wily faulty power crystals, which caused Gamma to fail.
* In ''Webcomic/{{Homestuck}}'', John decides to take advice on SequenceBreaking from a {{Troll}} while in the Medium, against the warnings of his closest friend. [[BadFuture It doesn't end well]].
** In the alpha timeline where John ''does'' listen to his friend, he then starts taking advice from [[SerialKiller Vriska]]. That doesn't end well either, but it ended badly in a way that was actually ending well in disguise. On the other hand, trusting Karkat, WV, and the Consorts turn out to be pretty smart moves.
* Nick in ''Webcomic/GeneralProtectionFault'' is the one who most persistently defends [[BitchInSheepsClothing Trudy]], in spite of Ki and Fooker's justified suspicions about her. The Surreptitious Machinations arc involves the cast racing to help him realize that his "Project Velociraptor" is the keystone of her plans, and it ultimately results in him realizing her duplicity and refusing to help her. After that, [[CharacterDevelopment he realizes that he can't always trust people blindly]], leading to him seeing through Trish's story (ironically, as Ki decided to give her the benefit of the doubt like Nick used to) and noticing [[spoiler:that the Ki who lured him into the Mutex is not the one he knows]].
** Mr. Jones of Goodman Rubber is one, as he, impressed with Fooker's skills, invites him to give a motivational talk (Fooker is every bit as good as Mr. Jones thinks and [[BrilliantButLazy perhaps better]], but he's also a BunnyEarsLawyer with a questionable sense of humor). He later laments how someone [[DevilInPlainSight as nice as]] [[ManipulativeBastard Trudy]] "fell in with that wrong crowd," and believes that [[SmugSnake Trent]] is far more competent than he actually is.
* Kevin of ''Webcomic/KevinAndKell'' is considered this as a result of being a fearless rabbit, which is implied to have been what led him to marry his first wife [[JerkAss Angelique]]. By the time the strip begins, though, he's smarter about people's ulterior motives.
* The entire faculty of Bumblebane's in ''Webcomic/WizardSchool'', with the exception of [[ObviouslyEvil Prof. Evilmore]]. It doesn't help that GoodIsDumb is in UpToEleven levels in the comic's universe. And probably all the students in Dragonbane House, with the exception of Celeste, who has [[FakeUltimateHero Graham]] pegged for the utter asshole he is, but has been instructed to help train him, and What The Faculty Says Goes.
* Flipside: It's implied that the cheating scientist's wife is one of the worst judges of character in the series; having failed to marry a good husband, she goes on a RoaringRampageOfRevenge trying to kill him, only to hire and strengthen her "honorable" bodyguards, the last of which is revealed to be a complete sociopath. It's implied that all she did in her life was find people she thought she could trust (because they were sociopathic and she incorrectly interpreted their hints as honorable traits), give them extreme amounts of power and skills (which they use to cause unfortunate collateral damage to bystanders), and in her last moments destroyed a vital piece of the puzzle for the Thin Man, who's less of a world conqueror and more of a WellIntentionedExtremist.

[[folder:Web Original]]
* Lizzie from TheLizzieBennetDiaries is hinted to be this, and a case of AccentuateTheNegative.
* ''Literature/TalesOfMU'':
** Amaranth. FriendToAllLivingThings taken to the logical extreme, or just an idiot? You decide. Although, to be fair, she really can't help the way she is, due to [[spoiler:her creation process being tampered with]].
** Mack, who has yet to learn that an awesome rack does ''not'' a good person make.
* In ''Machinima/RedVsBlue'', Donut mistakes Blue Base for a convenience store; and still somehow manages to get the Blue flag when Caboose mistakes him for a general. Later on, Donut mistakes the Meta (An insane soldier who by that point spoke exclusively in growls) as friends with Simmons (when in reality, the Meta was trying to kill Donut and Simmons), even mistaking the Meta's grenade [=launcher/bayonet=] combo as being a broom.
* ''AVeryPotterMusical'' plays with Dumbledore's trust of Snape in this way. In one scene, he accepts a sandwich that has a pipe bomb poorly concealed in it, then gets annoyed when Hermione destroys it.
--> I'm going to go make myself another sandwich, although I don't know how it can be as good as the last one. That one ''ticked''!
** It also takes Cornelius Fudge's refusal to believe Voldemort was back in the original series to the logical extreme. He denies it even as [[spoiler:Voldemort walks into his office and ''kills him'']]
* WebVideo/TheNostalgiaCritic is perfectly adept at pointing out ObviouslyEvil in movies, but fails in his own life. Not getting that WebVideo/TheNostalgiaChick wanted his power in ''WebVideo/{{Kickassia}}'' is a good example.

[[folder:Western Animation]]
* ''WesternAnimation/BeavisAndButtHead'':
** The title characters. Even when they get their asses kicked by Todd, they still think he's cool and aspire to join his gang. In fact, every single hoodlum, criminal, and {{Jerkass}} they meet is "cool" by their standards. Then again, when you consider their priorities and interests, it's not that surprising.
** In one episode they even "befriend" an escaped serial killer who is clearly deranged, is more or less openly planning on murdering them... and has the word "Killer" tattooed on his forehead (because they're both nearly illiterate, they read it as "Kyle-er" and think it's just his name).
** Most of the citizens of Highland are horrible judges of character; otherwise, the show wouldn't find itself repeatedly using the SeeminglyProfoundFool plot.
** Mr. Van Dreissen seems to be on an eternal, hopeless quest to bring out the "good" he claims to see in B & B. He sees everyone in that way, so his horrible judgement is pretty severe.
* In ''WesternAnimation/KingOfTheHill'' from [[Creator/MikeJudge the same creator]], the citizens of Arlen seem to be in the same boat. A good third of the series' episodes start off with the characters taking anything and everything a complete stranger tells them at face value, while simultaneously refusing to believe anything people they've been friends with/married to/the parents of for decades say. Some episodes give a reasonable excuse for this[[labelnote:Example:]]"Peggy's Fan Fair" concerns the title character learning that Music/RandyTravis recorded a song using lyrics she had mailed to him, without giving her credit; everybody sides with Travis over her because she has a reputation for [[SmallNameBigEgo having a massive ego]] and taking credit for things she had no hand in[[/labelnote]]... but most don't.
* Sparky's mother on ''WesternAnimation/AtomicBetty''. She tends to date supervillains a lot, even the show's BigBad on one occasion.
* ''WesternAnimation/SouthPark'':
** Cartman's mom seems to think he's a "little angel" to the point where she doesn't even question his story about why he has a picture of him with Butter's penis in his mouth in "Cartman Sucks". She also lets him get away with murder and always takes his side, with the exception of more recent episodes ("Tsst!", "Coon 2: Hindsight" and "[=HUMANCENTiPAD=]").
*** The members of the Mel Gibson fan club in "The Passion of the Jew", who are unaware that Cartman wants to restart the Holocaust and instead think that he just wants to promote Christianity.
** PlayedForLaughs in "Free Hat". The episode's titular character, Hat [=McCollough=], is a serial murderer of 23 babies, but a protest group wants him freed from jail, claiming he killed the babies in self-defense.
*** Or maybe it ''really was'' self-defense...
* ''WesternAnimation/TheTransformers'' had its fair share of examples. Arguably the worst case happens in "Megatron's Master Plan", which revolves around the Decepticons' plan to make the people of Earth (or at least Central City) believe that they were in fact the good guys all along... after how many very obvious instances they are not? And everybody actually believed it! Then when they were proven complete morons, the enslaved humans all blamed Shawn Berger, who while not having a great reason to help the Decepticons at least had the most reason to trust them, as the second main cause of their misery.
** "Enter the Nightbird" might be another case, depending how much sentience/sapience one reads in the titular character. Giant robot ninja armed with more weapons and powers than you can shake a stick at? Truly she is going to "benefit mankind, and not harm it".
** Orion Pax was one of these in his backstory. He was a ''Megatron fanboy'' who thought old Megs had Cybertron's best interests at heart. That ended when Megatron nearly killed him and his girlfriend after duping them into helping him. Orion's a somewhat better judge of character as the OlderAndWiser Optimus Prime.
* When talking about the ''WesternAnimation/TransformersAnimated'' Elite Guard the [[Wiki/TFWikiDotNet Transformers Wiki]] [[http://tfwiki.net/wiki/Autoboot_Camp noted that:]] "Sentinel Prime, the biggest jerk in Transformer history, and [[spoiler:Longarm Prime, a double-agent]], are both high-ranking members of the Elite Guard, while Optimus Prime, a true hero, [[AlmightyJanitor is a washout and space bridge repairbot]]. Either Optimus Prime did one major screw-up, or Ultra Magnus is the single worst judge of character ever."
** Since Optimus Prime's screwup was taking the blame for Elita's death on a planet they shouldn't have been on in the first place, Magnus does have a tiny bit of leeway. No excuse for making Sentinel Prime practically his right-hand-mech, though.
** Apparently, once washed out, you can't be brought back in, at least according to Magnus himself when talking to Optimus. And he probably keeps Sentinel Prime at his right hand [[KickedUpstairs so he can babysit him]]. We've all seen what happens when he's not around to keep the glitch-head out of trouble.
*** Which is made worse, as the [[Wiki/TFWikiDotNet Transformers Wiki]] [[http://tfwiki.net/wiki/Five_Servos_of_Doom later noted that]] "...Jazz was active in the Cyber-Ninja Corps during the war, apparently long before Sentinel even came online (much less joined the Elite Guard). Even ignoring Sentinel's various flaws, this raises legitimate questions about just how promotions are handed out in the Elite Guard."
** Given the praises Magnus have been giving him and saying how Sentinel could learn from him, there is a possibility of this being a SecretTestOfCharacter for Optimus.
** Megatron doesn't get off Scott-free. [[TheStarscream Starscream]] was a high-ranking member of the Decepticon forces for eons, and has been trying to off Megatron for a good deal of them. But Megatron seemed genuinely surprised when he found out it was Starscream who planted the bomb on him.
*** He learned his lesson after that, showing that, unlike most other Megatrons, he's not at all forgiving. Starscream shows up, and once he has his gun back, the first thing ol' Megs does is blast Starscream square in the face. He proceeds to wash, rinse, and repeat as necessary whenever the guy shows his face.
*** That doesn't change the fact that it took ''several million years'' for him to finally come to this conclusion.
*** To be fair this Starscream is pretty smart as well, so odds are he only tried to off Megatorn when there were Autobots around.
*** Well, he made it clear he didn't trust Starscream. He just didn't expect him to have the balls to attempt something in case it backfired (Starscream is an enormous coward should the tables ever be turned on him). Still, he's far smarter than G1 Megatron, who knew perfectly well Starscream would try and kill him if he so much as tripped on an acorn and still kept him around and did nothing about it. Then ''WesternAnimation/TransformersTheMovie'' came along and Megatron realizes just [[TooDumbToLive what an idiot he'd been]].
* Dave from ''WesternAnimation/DaveTheBarbarian'' constantly insists in a single episode that a princess [[NamesToRunAwayFromReallyFast named Evil Princess]] is not evil despite the fact she "[[ObviouslyEvil says she's an evil princess, looks like an evil princess and has]] [[TooDumbToLive 'Evil Princess' stitched on her hankies]]."
* ''WesternAnimation/AvatarTheLastAirbender:'' The Earth King fits this trope to a T. Though, in his defense, the villain in question has raised him since he was ''four'', and never did anything to hurt him personally until after his other crimes were uncovered and the king imprisoned him without even bothering to hear his side of things.
** Most people who trust [[MagnificentBastard Azula]]. This includes Zuko, who really should know better (although with him, Azula is just adept at telling lies he ''really'' wants to hear, and occasionally mixing just enough truth into it).
* ''WesternAnimation/BatmanTheAnimatedSeries'': "It soon became obvious to me that The Joker, so often described as a raving homicidal madman, was actually a tortured soul crying out for love and acceptance..." Doctor Harleen Quinzel (aka [[VillainousHarlequin Harley Quinn]]), welcome to the list.
* ''[[WesternAnimation/AdventuresOfTheGalaxyRangers Galaxy Rangers]]'' - King Spartos of Tarkon had a really bad habit of trusting advisers that told him what he wanted to hear, despite his daughter's objections and knowledge of the wider galaxy. It's only towards the end (and with the use of some AppliedPhlebotinum from the Heart of Tarkon) that he's able to see his daughter and the Rangers are correct.
* ''WesternAnimation/TheSimpsons'': in the book ''Angelica Button and the Dragon King's Trundle Bed'', the snake Lord Evilton is the minister of niceness.
** Zig-zagged with Lisa in the episode "Lisa's Date With Destiny" where she gets a crush on Nelson Muntz. (Even Bart thinks this is crazy, telling her, "I'll probably never say this to you again, but you can do better!") It's not that Lisa doesn't know that Nelson is a rotten kid, she just honestly believes that he might have a sensitive side, and she might be able to change him. By the end of the episode, however, she realizes that Nelson is rotten through and through, and they break up.
** Although, in a subsequent episode, she does a favor for him, and when asked why, she shrugs and says, "Well, we used to date."
* ''WesternAnimation/InspectorGadget'' would often confuse MAD agents for the good guys, and sometimes even assist them if needed. He [[UpToEleven took it to eleven]] in the Christmas special when he thought Dr. Claw was SantaClaus, and arrested the real Santa.
** Luckily for the good guys, Gadget is such a WalkingDisasterArea that he is more liable to thwart the bad guys when trying to help them than when trying to stop them.
* ''WesternAnimation/ThePowerpuffGirls'': In one episode in which the Gangreen Gang are forced to attend Pokey Oaks by a truant officer, Ms. Keane accepts them with open arms, and when the Powerpuff Girls counter their antics and attempts to torment the kids, Ms. Keane ''only'' sees the Girls assault them and punishes the girls while letting the Gangreen Gang get away with it. It's only when they brutally injure the other kids in a game of dodgeball that Ms. Keane realizes that the PPG were right about the Gangreen Gang all along.
* Lois displays this in one episode of ''WesternAnimation/FamilyGuy'' when she learns that she has a brother, Patrick, who was committed to a mental hospital and has him released, and shortly afterwards a serial killer nicknamed 'The Fat-Guy Strangler' begins targeting Quahog's obese citizens. She's reluctant to consider the possibility that Patrick may be connected to the killings even though he plasters his bedroom walls with photos of himself strangling fat guys, and he has the corpse of a fat guy under his bed, next to a half-dead fat guy who claims Patrick tried to kill him.
-->'''Lois:''' So he has a lot of pictures of himself strangling fat guys, that doesn't make him the Fat-Guy Strangler!\\
'''Brian:''' Oh yeah? What about the dead fat guy under his bed?\\
'''Lois:''' Coincidence?\\
'''Brian:''' What about the half-dead fat guy in the corner?\\
'''Fat guy:''' Patrick tried to kill me.\\
'''Lois:''' Maybe it's a different Patrick.\\
'''Brian:''' ''LOIS!''\\
'''Lois:''' Okay, okay!
* Prock in ''WesternAnimation/TheAwesomes'' is this when it comes to women he's interested in. Mostly relevant because of his blindness to [[spoiler: Hotwire's]] fairly obvious double agent role, but it also shows three of his earlier dates: A normal looking girl who, on being introduced to his father, sprouted flames and attacked him. A woman with green skin and hair who, on being introduced to his father, turned into a LizardFolk and attacked him. And a robot with buzz-saw hands and rocket launcher shoulders wearing crudely applied lipstick and a wig.
* In the ''WesternAnimation/SquirrelBoy'' episode "Islands in the Street", when Andy teams up with the local {{jerkass}} Kyle to find Rodney and Salty Mike, Bob sees Kyle throw out his car's cup holder in disgust and declares "He seems nice."
* ''WesternAnimation/GravityFalls'': The eponymous town seems to have made it a ''habit'' of celebrating [[VillainWithGoodPublicity the wrong kind of people]].
** Lil' Gideon is fawned over as an adorable child and a brilliant psychic. In reality he is a [[AxCrazy completely insane]], [[spoiler: attacking Dipper with ''[[DisproportionateRetribution lamb shears]]'' for "getting between" [[{{Yandere}} he and Mabel]] ]], and later summoned a ''demon'' so he could steal Stan's deed to the shack. [[spoiler: The townspeople finally learn the truth when Stan exposes his illegal surveillance cameras, and cart him off to jail]].
** The Northwest family are the idolized founding family of Gravity Falls, but are pretty condescending toward regular people. [[spoiler: And as turns out, they never founded the town, and have been scamming and screwing the residents for a ''century and a half'']].
* In TheMagicSchoolBus, this trope is usually restricted to Arnold's view on his [[BigSisterBully cousin]] [[ManipulativeBastard Janet]]. However the rest of the class joins in the butterfly episode where they think [[NiceGirl Pho]][[ShrinkingViolet ebe]] ''must'' be sabotaging them by suggesting they make the school mascot a butterfly because the team they'll be facing is from Phoebe's old school on Janet's word alone.

[[folder:Real Life]]
* UsefulNotes/WarrenHarding, whose Secretary of the Interior, Albert Bacon Fall, leased tons of land to his buddies in exchange for massive bribes in the Teapot-Dome Scandal, which was the worst scandal in American politics [[UsefulNotes/RichardNixon until Watergate]].
* Nearly 50 years earlier, UsefulNotes/UlyssesSGrant saw the second term of his presidency marred by corruption scandals involving several members of his Cabinet; despite the fact Grant himself was honest.
* Jefferson Davis was this as well -- he thought himself a great judge of character while really he was mostly just a great judge of who liked him and who didn't.
* Sadly, it is not uncommon for a man or woman in an abusive relationship to be stigmatized as this trope, especially if the manipulator still [[WhyDidYouMakeMeHitYou has them convinced]] that [[SorryIFellOnYourFist the abuse isn't]]. While true stupidity and massive lapses in judgment happen, it is important to remember that victims of a good manipulator can fall all over the spectrums of cleverness and personality type. Tropes don't cover it.
** Similar to this, another unfortunate (more specific) example can come in the form of someone who has been raped - sometimes as a child, but sometimes not - in the past. Some survivors describe it as their "filter being broken" due to the rape.
* Every woman who sent Ted Bundy love letters and wedding proposals while he was on trial for serial murder; Bundy was in fact a charming, charismatic, and handsome individual, which is how he was able to lure so many women to their deaths. It's amazing what a person can get away with if he has a dazzling smile.
** Even scarier is that some of them knew exactly what kind of person he was, and [[http://en.wikipedia.org/wiki/Hybristophilia just found this extremely sexy]]. It's disturbing how many women elevate serial killers to heartthrob status. AllGirlsWantBadBoys played to its skin-crawling extreme--Bundy is not the only SerialKiller (or any type of murderer) to be bombarded with love letters--Richard Ramirez, aka The Night Stalker, terrorized California for months with a series of brutal murders, yet eventually ''married'' one of his many groupies. Scott Peterson continues to receive large amounts of money from lovestruck women, even as he sits on death row for the murder of his pregnant wife, and within months of his wife disappearing (the ''second'' of his four wives to meet with foul play at his hand), Drew Peterson was engaged.
** Males aren't exempt from this stupidity either. Karla Homolka and her husband raped and murdered several young women, including her ''sister''. She gained early release from prison by claiming (falsely) that she'd been an unwilling participant and married one of her admirers. Meanwhile, Casey Anthony (who in all likelihood, killed her daughter, despite being found not guilty) received numerous love letters from men begging her "Will you be my girlfriend?"
* During UsefulNotes/WorldWarII, Franklin Roosevelt felt that he could trust Joseph Stalin more than Winston Churchill, in part due to his desire to dismantle the British Empire, and therefore didn't pressure Stalin as much as he might have regarding the shape of postwar Europe. Obviously, he died before the end of the war, but felt bitterly disillusioned shortly before his death.
** Lenin felt like Stalin was the man for the job for many things. He put him in charge of Georgia, then Stalin had the Mensheviks executed (which Lenin didn't want). In short, Stalin was a ManipulativeBastard and Lenin only realized his mistake (if he did) shortly before his death when he made his testament (which the Stalinists thought was a fraud).
* It seems like 80 or 90% of any decent-sized fandom is this, [[DracoInLeatherPants if the shipping is anything to go by]]. Come up with the most [[CrackPairing ridiculous, bizarre, incompatible pairing]] and [[{{Rule34}} there will be someone who thinks it's a great idea]]. Character be damned.
** You could argue that that has more to do with the fans living out vicarious fantasies- they may be well aware that the pairing makes no sense, but they just want to see it happen to satisfy their own PerverseSexualLust.
** Same thing for how fans interpret WordOfGod. They seem to scream DeathOfTheAuthor when said author is usually truthful in what he says, yet authors that tend to lie and troll their fans seem to have everyone taking their every word as gospel truth no matter how often it turns out to be a lie. Fans are generally really, really bad at figuring out the character and values of creators...
** {{Hatedom}}s are this at the other end of the extreme: Whatever they hate has ''no'' redeeming qualities whatsoever, and to hell with the facts.
* An excerpt from [[BunnyEarsLawyer William Lyon Mackenzie King's]] diary: "[[[UsefulNotes/AdolfHitler Hitler]]] is really one who truly loves his fellow-men, and his country, and would make any sacrifice for their good...the world will yet come to see a very great man–mystic in Hitler..."
** As pointed out below, many leaders at the time saw Hitler as a good leader. To be fair, he was known for being passionate and charismatic, and made many promises to better the lives of the German people... at the expense of everyone else. There was also the fact that Mackenzie King was known for trying to see the good in all people, and was a very spiritual man, which probably caused him to try and ignore Hitler's increasingly obvious faults.
*** Given Mackenzie King's apparent love of Hitler; his famous statement, when asked how many Jewish refugees Canada would accept during the war, that "none is too many"; and his predilection for holding seances to receive governing advice from both his dead mother and ''his dead dog'', it may simply be that the people of Canada were at that time ''collectively'' horrible judges of character.
* Many Western European politicians and intellectuals (Churchill included) initially saw Hitler as the right man for Germany.
** Hitler and the Nazi high command also trusted their spies, even though ''every one'' of them had become a DoubleAgent for the British very early.
** Josef Stalin was genuinely shocked, to the point that he supposedly went on a [[DrowningMySorrows week-long drinking binge to cope]], when Hitler double-crossed him.
*** This really needs stressing. Josef "Paranoia" Stalin of the Great Purges, who liquidated his pre-revolutionary Bolshevik comrades, who had thousands of his own people shot and starved because he thought they ''might'' be plotting against him. ''He'' trusted ''Adolf Hitler'' to keep his bargain.
* Pretty much all dictators come to power this way because the people in the country think they look like a pretty cool guy.
* Gaston Glock, founder of the Glock handgun manufacturer. When he was first setting up the distribution side of the business, he met a businessman in Luxembourg, Charles Ewert, who convinced him he could help. Later, in July 1999, Ewert hired a French contract killer to murder him, in order to prevent him from uncovering the large embezzlement of company funds. Despite getting beaten badly with a mallet, Mr. Glock survived, kicking his attacker and driving him off; his attacker was given 17 years in jail, and Ewert 20 for hiring him.
* During the Three Kingdoms Era of China, Shu Kingdom's Prime Minister Zhuge Liang, despite being a military genius in the battlefield, was this according to his legendary nemesis, Wei Kingdom General Sima Yi. During the Battle of Jie Ting, Sima Yi banked on Liang to make the mistake of choosing an inspiring yet inept commander who would make a mistake he could exploit. The mistake that the commander made dealt such a huge blow to Shu that Zhuge was forced to execute him.
* UsefulNotes/NapoleonBonaparte appears as this in the writings of many of his admirers who, taking their cue from his own memoirs, liked to blame his reverses on the alleged incompetence, if not the outright treachery of key subordinates in order to present him as an infallible military and political leader. But these subordinates would only have been able to do the damage ascribed to them because Napoleon himself appointed them to their positions...
