Super Gullible

Go To

"However, containment efforts are aided by the fact that SCP-3740 is remarkably gullible. SCP-3740 accepts almost all statements at face value, and displays no traces of skepticism or uncertainty."

Sometimes people just don't get the idea of jokes or lies and are seemingly tuned to believe anything people tell them. They might be The Ditz, very pure or what have you, but the net result is that when someone tells them ridiculous stories that no sane person would find even slightly credible they'll believe it wholeheartedly. Sometimes, however, it actually works in reverse: A character will tell them something that is completely true but rather strange and the character will refuse to believe it.


See also The Ditz, Easily Impressed, and Genre Blindness. May be a Horrible Judge of Character. Not to be confused with Gullible Lemmings. The polar opposite of this trope would probably be The Paranoiac, who is incapable of trusting others. Contrast Won't Get Fooled Again.

    Anime & Manga 
  • Sakura of Cardcaptor Sakura always believes any tall tale her classmate Takashi tells her without fail. Most new transfer students also tend to fall into this, which is eventually lampshaded by Takashi's girlfriend in Cardcaptor Sakura: Clear Card.
    Chiharu: [while angrily throttling Takashi] YOU FOUND YOURSELF ANOTHER VICTIM! ARE YOU HAPPY NOW?!
  • Tohru Honda in Fruits Basket is quick to believe any story or legend told to her, something Shigure finds funny and usually teases her with stories.
  • Henneko: The Hentai Prince and the Stony Cat: Tsukushi Tsutsukakushi is the strict president of the track and field club, but she is so gullible that she believes Youto's ridiculous excuse that he's innocent of the perverted acts she's determined to punish him for because they were actually committed by his (made-up) identical twin brother. As a result she continues to trust him like she always has while attributing anything naughty he does to his twin brother, and when she catches him in an Accidental Pervert situation she takes him for his brother and refuses to believe him when he tries to explain that the "twin brother" thing was a lie in the first place.
  • Tsubame from Kaguya-sama: Love Is War is a bit superstitious, and often asks people for advice, generally believing everything they say. Shirogane's father, currently working as a fortune teller, gives her relationship advice during winter break, only to subvert the seriousness of his words by offering her a phony trinket that would help her, which she immediately buys, causing him to call her out on her gullibility. It's Played for Drama later on, as she heeded Yume's advice on having Pity Sex with Ishigami after rejecting his confession, leading to the incident that broke Iino's arm and further complicated a Love Triangle between the three. In Chapter 191, she still seeks out Papa Shirogane's advice before learning he's closed down the fortune teller shop, hinting that she hadn't learned her lesson even after overhearing Maki in Chapter 161 note that those kinds of trinkets are obvious scams.
  • Dragons in Miss Kobayashi's Dragon Maid are not stupid, but their simple worldview means that they are very easy to fool. Of course, it isn't exactly a smart decision to do this as pissing off a several story tall apex predator tends to be bad for one's health.
  • Wakamatsu in Monthly Girls' Nozaki-kun is adorably naïve and willing to believe what people tell him. Even the nicer characters like Sakura and Hori will do it, such as claiming there’s no seniority in culture clubs, finding out they can’t apply screentones while Wakamatsu can and then instantly and arrogantly shoving the work off on him, completely reversing what they had said before.
  • Musuko ga Kawaikute Shikataganai Mazoku no Hahaoya: Lorem can be convinced to do anything if she believes it will make her baby son Gospel happier. Chiharu quickly gets Lorem to eat a vegetable stir-fry, which she would never touch otherwise, after telling her that it makes her breast milk more nutritious and taste better.
  • Youko in My Monster Secret is as terrible at telling lies as Asahi, but also falls for them even more easily than he does. And when Karen is introduced, she turns out to be such a Nice Girl that the words "doubt" and "suspicion" seem thoroughly absent from her dictionary.
  • Ayaka in Negima! Magister Negi Magi tends to believe a lot of what she hears given how naïve she is. At one point Chisame needs to distract her and the only thing she can come up with is that Chao is Negi’s fiancée and they’ll have to get married if he loses to her, lampshading how absurd her lie is. Ayaka buys it. She also believes her when she says her Magitek wand that brings them inside the world of the computer is just how video games work now.
  • Nichijou: When Izumi Sakurai finds a dirty magazine in her younger brother's room, she completely buys his excuse that he's holding it for someone.
  • One Piece
    • This is pretty much the hat for the whole Tontatta Tribe. Their tendency to believe everything people say has been exploited by heroes and villains alike. "Tonta" even means "foolish" in Spanish.
    • Chopper can often be rather gullible, especially when it comes to believing Usopp's lies. He and Luffy are the only ones who don't immediately catch on to the fact that "Sogeking" (Sniper King) is Usopp in disguise, despite the fact that Usopp's just wearing a mask and a cape, and that some people who'd only met Usopp the previous day can see through his disguise.
  • Oshigiri from The Ones Within, as part of his "cute dork" schtick. He combines this with Curious as a Monkey in an omake, where he finds himself wondering uncontrollably if the insults a teammate threw at him have some kind of deeper meaning (they don't).
  • Throughout multiple season of Pokémon, Ash and his friends repeatedly fall for every Paper-Thin Disguise that Team Rocket uses, with very rare exceptions.
  • Ranma ½: Ryōga's naivety and trusting nature makes him everyone's victim, especially Ranma, who repeatedly uses his girl form to either spy on him, or dupe him. You'd think Ryōga would eventually learn to recognize his face or voice — but he never does. Even when Ranma's using little more than a pair of glasses as a disguise. The most egregious instance being, when Ranma is even able to convince Ryōga that he is his sister. Ryōga figures it is plausible, given he hadn't seen his family in years, due to his poor sense of direction.
  • Sailor Moon: In the first season finale, the DD girls create an illusion of a captured Tuxedo Mask, causing Usagi to run toward it. After the trap is exposed, they create the same illusion again... and Usagi does the same thing.
    Sailor Mars: Yeah, right. Do you really think she's [sees Sailor Moon running toward the illusion] stupid enough to fall for it AGAIN?''
    Sailor Moon: But what if it really is him this time?
  • Servant × Service by the same author as Wagnaria!! has its own Popura expy with Lucy, who is incredibly willing to give out personal information for flimsy reasons or believe Chihaya’s terrible lies.
  • Shimoneta: Oboro takes the concept of Just Following Orders to its ludicrous extreme. As head of the school's Decency Prefects, his job is to confiscate any material that's considered lewd. So when he tries to take Fuwa's yaoi doujin, Fuwa contends that it's research material. Oboro immediately believes her and authorizes the book. However, Tanukichi tells him it's smut, so Oboro promptly takes the book back and bans it. The gag continues back and forth like this for several moments.
  • Yor Briar-Forger of Spy X Family may be a badass assassin, but she's also a Socially Awkward Hero and Cloudcuckoolander who buys Loid's flimsy excuses that the goons trying to kill them are his psychotic patients that he's using "concussive therapy" on.
    • Her brother Yuri is a member of the secret police, but has a huge sister-complex that makes him just as gullible when it comes to Yor. When he gets suspicious that Yor has supposedly been married for a year, she claims that she "forgot that she forgot" to tell him, and Yuri buys it. One flashback to their childhood showed Yor returning home covered in blood, not even giving an excuse beyond "I'm totally fine", and Yuri shrugs it off.
  • In The Useless Senpai and The Talented Kouhai, Ochiai agrees to get the mops out of the storeroom while the first-years put away the balls. She realizes too late that they tricked her to sneak off, leaving her with the task of cleaning the gym.
  • Popura from Wagnaria!! will believe any ridiculous lie Satou or Souma tell her, such as that eating dried geckos will help her grow taller. She also somehow fails to realize that Souta and Kozue knowing each other and having the same last name while living in the same neighborhood is probably a hint that they’re siblings.
  • Kirie from World Trigger believes anything other people tell her, no matter how ridiculous. This includes believing Jin when he said Osamu, Chika, and Yuma were his siblings when they don't look alike at all.
  • Kido from Zatch Bell! always believes whatever bizarre things Dr. Riddles tells him and then Riddles responds with "It's a lie!"(or "Kidding!" in the dub) much to Kido's dismay.

    Fan Works 
  • Cheating Death: Those That Lived has a 50th Hunger Games Career whose fatal flaw was being too trusting. She's killed by one of her now-former Career allies when she turns her back on her.
  • The Outside downplays this with Satsuki. Being agoraphobic with no real world experience, Satsuki wouldn't doubt what she's heard if she didn't see the event or wasn't present when it happened (i.e, being asleep at home and not at the park when Ryuuko got hurt), however, she does have moments of skepticism (her back and forth with Aikuro in Chapter 4).

    Films — Animated 
  • Dug in the Pixar short Dug's Special Mission. He happily accepts Alpha's painfully flimsy excuses about why the "special missions" that Alpha's sending him on are necessary (they're really Snipe Hunts meant to get him out of the way).

    Films — Live-Action 
  • The Thermians of Galaxy Quest have no concept of theater and have only recently learned about dishonesty courtesy of Sarris, so they unquestioningly believe that the broadcasts from Earth are "historical documents" and that the actors of the Galaxy Quest TV show are real space heroes. When they find out the truth, they don't take it well.
  • Played for Laughs in The Gamers: Dorkness Rising: Sir Osric, The Paladin (and a GM PC), tries to keep the party on a morally upright path, but whenever they need to do something illegal, they simply Bluff him into running out of the room to fight some non-existent evil. Because his Sense Motive skill is so low, apparently, it works like a charm every time.
  • Lingk in the play and film version of Glengarry Glen Ross is not only an Extreme Doormat and Henpecked Husband but he also swallows every lie the Shady Real Estate Agent Roma feeds him without getting suspicious. Even when one of Roma's statements is exposed as untrue by a third person, Lingk's reaction is to apologize for letting Roma down.
  • Justified in The Invention of Lying which is set in a world where no one has any concept of lying whatsoever, which means that people believe the protagonist (the only person able to lie) no matter how ridiculous his lies get. Lines like "I'm not here" and "we have to have sex right now or else the world will end" are taken at face value.
  • Woody in Nebraska — it's extremely depressing to see an elderly man get his hopes up over receiving a "Big Winner!" letter for a million-dollar sweepstakes.
    Receptionist: Does he have Alzheimer's?
    David: No, he just believes what people tell him.

  • One of Isaac Asimov's George and Azazel short stories is about a police detective who believes the most ridiculous stories told by the suspects (like a shop robber saying that the owner gave him a gun and started putting money in his pockets). Azazel makes him a Living Lie Detector to compensate... causes some problems with his girlfriend, but that's another matter.
  • Everyone in Graceling Realm becomes this when Leck is involved. Lying is his Grace, so even if the lies are several times removed from the source, people believe them despite how very suspicious they are. Po is the only one who can see through it.
  • Valentine Michael Smith in Stranger in a Strange Land is a man raised by Starfish Aliens on Mars. When he first arrives on Earth, Mike has no concept of lying. He is Easily Impressed by a televangelist claiming contact with God. His friends painstakingly explain that, unlike Martians, humans are not Brutally Honest and can even be dishonest.
  • Angels in Unsong start out unable to even comprehend the idea of lying. Of course, extended contact with humanity tends to eventually cause them to figure it out which also leads to them having breakdowns.

    Live-Action TV 
  • Mr. Gullible the substitute teacher from The Amanda Show, as his name implies, is really gullible. When someone would tell him an obvious lie, he would ask them "Really?" and then he will believe the lie as long as everyone who's in on the lie agrees it's true.
  • From Better Call Saul, Jimmy and Chuck's father was the epitome of Stupid Good, running his own business into the ground because he believed every sob story he was told no matter how blatantly false it was and handed out money and sometimes even free merchandise from his store to anyone and everyone who came to him with one.
  • Full House: Danny and Joey are playing basketball, and Joey tells Danny the door to the womens' locker room is open and steals and shoots while Danny is distracted. Joey has done this before, and Danny claims the only reason he still falls for it is because one time it really was open.
  • Barney Stinson from How I Met Your Mother is an adult yet still believes all the ridiculous lies his mother told him as a child. This is also quite ironic, considering that Barney is a notorious liar himself.
  • Kaamelott: Arthur is repeatedly able to convince the chieftains of enemy tribes to go away thanks to this trope.
    • In one case, he tells a Viking allied with the Burgund king that the Burgund was giving up all his lands (the Burgund doesn't speak their language and tends to repeat what he just heard because it sounds funny to him) with this exchange:
      Arthur: I'll give you the entire Burgund territory.
      Sven: You wha...? And... he agrees with this?
      Burgund: HE AGREES WITH THIS!
    • In another instance, the Burgund king is attacking Kaamelott when Attila the Hun shows up. Arthur then tells Attila the Burgund is in fact here as his ally, despite the Burgund screaming "Attila! Attila!" in a panic and Arthur yelling at him to shut up before he screws everything up. Attila falls for it.
    • And in another where the Mongol horde shows up (all two of them), Arthur convinces Attila that the castle doesn't contain anything of value at all, to the point where Attila's demands keep going lower (at one point demanding the table linen, but Bohort refuses). In the end, he demands the queen, gets Arthur's Ax-Crazy bodyguard Grüdü in obvious drag, and accepts her as the real deal.

  • Valvatorez in Disgaea 4: A Promise Unforgotten will believe lies told about his own motives and actions. He also thinks that Axel is a noble compatriot who died in the line of duty when he was entirely and openly hostile to them throughout every appearance. Why? Because Fenrich said so.
    Fenrich: My lord's undoubting heart is another of his formidable abilities.
  • Gatrie, the Nice Guy Armor Knight of the Greil Mercenaries from Fire Emblem: Path of Radiance is extremely easy to take advantage of, as revealed in his support conversation with his Heterosexual Life Partner and Vitriolic Best Bud Shinon. There, a woman he tries to woo manages to get all of his money to "pay for an operation" because she is "terminally ill" with "Brain Stones." She runs off, never to be seen again. In a twist, Gatrie is actually aware of his gullibility, but thinks that it makes him charming.
  • In Hades, Zagreus shares some of his feats to Orpheus, some of them true but more often aren't, like how he and Dionysus are actually the same person. Orpheus takes in all of it completely seriously. By the time he composes a ode of Zagreus' supposed feats, Zagreus admits he made up a lot of those stuff but Orpheus think he's just being humble. It ends up lampshading how the game and the real-life myths differ from each other.
  • In the Sonic the Hedgehog series, this was originally Knuckles the Echidna's defining characteristic. Having grown up in total isolation, it was easy for Dr. Robotnik to convince him that Sonic and Tails were the bad guys. Later on, though, it got Flanderized into general stupidity.
  • Sword of Paladin: While grieving over Clifford's death, Chris somehow believes Lancelot's lie that Nade and the rest of the party caused the orc attack on Bokka Village, despite how as one of the party members, Chris would be able to confirm their alibis.

    Visual Novels 
  • Sunohara in CLANNAD consistently falls for Tomoya’s bullshit, even being convinced once that he was dreaming simply because he didn’t believe Tomoya would remember the capital of Australia. Or being woken up after class and being told that they were living in a post-apocalyptic wasteland and that Tomoya was a robot duplicate of the original Tomoya.
  • Danganronpa:
    • While nowhere near the extent of other people on this list, Hifumi Yamada never thinks to question Celestia (the self-professed Queen of Liars) on anything she says. This includes telling him that Kiyotaka (the Ultimate Moral Compass) raped her, and assuring him that she wouldn't kill him as part of their joint murder plan, despite it putting Hifumi in a perfect position to be killed to stop him from giving her away and complete the constructed narrative.
    • Played for Drama in Danganronpa 2: Goodbye Despair. Near the middle of the third chapter, Ibuki Mioda catches a disease which Monokuma released on the island with random, personality-affecting symptoms. Among the three who contracted the disease, she was unlucky enough to get 'gullibility' as her symptom, which made it easy for Tsumiki — the nurse who was supposed to be caring for the sick — to strangle her to death; Mioda quite literally went along with her own murder without suspecting a thing.
    • The What If? side-story Danganronpa IF reveals Mukuro Ikusaba to be this regarding anything her sister (the Big Bad of the franchise) says when she needed to get a blood transfusion for Naegi but didn't know his blood type. Despite said sister being the reason he was bleeding out in the first place, Mukuro followed her instructions without suspecting a thing (repeated several times during that passage for emphasis on Mukuro's gullibility). She had to be told right to her face that she was being tricked, after nearly giving Naegi the wrong transfusion.
    • As a result of having raised in the forest, Gonta Gokuhara from Danganronpa V3: Killing Harmony is this as in the start of Chapter Two, he honestly believed Kokichi Oma when he stated that he was a honest and trustworthy man.
    • While not to extent of Gonta, Tenko Chabashira from the same game is this as she will believe anything that was said by her Neo-Aikido master, such as that her moves can get weakened by getting too excited for holidays, eating more than three sweets per day, or having men touching her. Note that the last thing is what ended up contributing to her disdain for men despite her mentor also being male, and she was still gullible enough to not notice that contradiction. And it is suggested that her master was even joking around while saying all this, but Tenko took it all seriously!
  • Chris in Majikoi! Love Me Seriously! has this weird thing where she acts super suspicious of Yamato, but then believes whatever absurd ideas he tells her, even correcting himself to continue the lie after he gets caught. Interestingly, the one time she doesn’t believe him is when he tells her about the Japanese folk remedy involving sticking a spring onion up someone’s ass as a cure for colds and other ailments.
  • Yumina in Yumina the Ethereal is basically brainless, so she’ll easily buy into whatever lies Ayumu tells her. She’s also easily flattered into doing things she wouldn’t normally want to.

  • Almost everyone who interacts with the so-called Light Warriors in 8-Bit Theater is not only easily fooled but stays fooled up until it would be funny for them not to be. At one point, a while after Thief tricked Berserker into trying to kill Ranger, this happens:
    Ranger: I asked the Light Warriors why they set us 'gainst each other.
    Red Mage: Ghosts.
    Thief: Aliens. Ghost aliens.
    Red Mage: Who possessed us.
    Thief: From space.
    Rogue: I didn't know there were ghost aliens.
    Cleric: But if they possessed people, I bet they'd do it from space.
    Ranger: Agreed. Their story checks out.
  • Exterminatus Now. The Cerberus demon falls for the "pretend to throw the ball" trick. It is a dog, after all.
  • Lola and Mr. Wrinkles: Lola easily falls for Mr. Wrinkles saying he has a spaceship in the backyard, as she thinks his unusual appearance means he's an alien cat. She still hasn't realized it was a joke at her expense two hours later.
  • Rosebuds: In one strip, Maria pesters Rosa to let her help with cooking. In response Rosa tells her to help by holding a bowl of fried potatoes and stand by the fridge, telling her that it would bring blessings to the table. Maricela lets Maria know how easily fooled she was, but Maria fails to catch it even when she is told.

    Web Original 
  • SCP Foundation: SCP-3740 (Ashur, God of the Windswept Plains and Soaring Skies) has a bad case of this, which actually makes him fairly easy to contain despite being the Physical God of wind and perfectly capable of calling tornado-force winds at will. He has successfully been convinced that his containment cell is actually the Gods' heavenly abode and that the research staff are all fellow deities of his pantheon; proof of godhood can be such things as mundane prestidigitation, having dyed hair and using the light switch, so long as they're given a little spin. And of course, when a real deity drops by to check in, SCP-3740 doesn't believe him to be one. The deity in question is more than happy to let the Foundation take care of him.

    Web Videos 
  • Invoked in Acquisitions Incorporated season 6, when Binwin tries to figure out whether Danielle is pulling a fast one on him and rolls for Sense Motive, and Aoefel bursts out into laughter because Binwin's Wisdom modifier is -1 and he would probably believe whatever Danielle said — even if she were just making handfarts.
  • Game Grumps. Danny is very susceptible to this. Sometimes he will catch on to when he's being fooled, but it doesn't take much to convince him otherwise.

    Western Animation 
  • In the Big City Greens "Random Rings" short "Cricket and Tilly Call Area 51", Cricket and Tilly call a store called Area 51 Comics, but believe they're actually calling the Area 51 and talking with an alien race. Izzy, the cashier, realizes how naïve and foolish the children are, and plays on their gullibility to keep up the act with them, and when Cricket reveals she's been faked out, she tricks them into hanging up in a panic by making them believe agents will be coming to their home.
  • Invader Zim: Zim believes everything he's told by the Almighty Tallest, regardless of how ridiculous it is. During "The Nightmare Begins", he gets assigned to a target that is clearly a Post-It note stuck to the side of the map and never doubts that he's on a Secret Mission for a second.
  • In King of the Hill, Peggy's inflated sense of her own competence often leads her to being manipulated or conned by less scrupulous individuals. The crowning example of this is when a death row inmate tricks an unwitting Peggy into smuggling cocaine to him by claiming he had her as a substitute teacher as a child—even though, as the inmate himself later points out, he's clearly way too old to have ever been taught by her.
  • The Loud House: Leni Loud, being The Ditz and all.
  • My Little Pony: Friendship Is Magic: Fluttershy tends to zig-zag with this. Her kind nature more-or-less makes her an easy target for manipulation, as shown in the episodes "It Ain't Easy Being Breezies" and "Daring Doubt". That being said, Fluttershy can understand when she's being taken advantage of like when trying to reform Discord, she immediately sees what Discord has been doing behind her back and in the same episode, she takes offense when her friends imply that she, in her own words, is a "silly, gullible fool". Most of these situations can be a case of Depending on the Writer though.
  • In early seasons of The Simpsons this was one of Superintendent Chalmers' characteristics in relation to the lies Principal Skinner told him. The greatest example of this is him believing Skinner's story that the northern lights were occurring in the kitchen when it was actually a really bad fire.
    • No matter how many times Bart prank calls Moe, he'll always shout out the Punny Name indicated before the realization sinks in. Bart's not his only tormenter, as his regulars find him an easy target for pranks as well, and in "The Springfield Connection" his friends get past his reservations about gambling at the Simpsons' house (Marge being a cop at the time) by telling him it's Vegas.
  • The title character of Spongebob Squarepants being The Ditz and the Cloudcuckoolander, he naturally believes anything he's told. Best exemplified in the episode "Gullible Pants".
  • Steven Universe: The Ruby Squad accept absolutely every statement at face value, even if it's made by someone who couldn't be acting more unnatural if she tried, or is blatantly impossible, like the lie that their target Jasper is on Neptune.
    Ruby Fusion: Why didn't you say so!?
  • Starfire from Teen Titans (2003) lacks experience with Earth culture and tends to accept explanations without a second thought, since the culture difference is so large that it's hard to tell crazy from crazy.
  • Wreck-Gar of Transformers: Animated is The Ditz, believing whatever anybody last told him, even if it was contradictory to what he was previously doing.

    Real Life 
  • According to some theories of autism, autistic people may lack of "Theory of Mind", or the ability to understand another person's point of view or mindset. This may lead to the person with autism believing nearly everything he or she is told, even if the information is obviously false to everyone else.


Video Example(s):


The Gullible Prison Guard

These are highlights from the following short, where the running gag is the wily and serious-minded prisoner tries playing mind games and makes persuasions on the easily deceived and credulous prison-guard, and would always end up back in jail. Yet this prison guard, in particular, is so naive and scatterbrained, that his actions later on reach the levels of being too-dumb-to-live when literal-minded, and becomes a loony foil for the prisoner.

How well does it match the trope?
