* ''Film/TwentyTwoJumpStreet'': {{Discussed}} and leads to an EurekaMoment. While chatting with a therapist about their partnership issues, the therapist tells Schmidt and Jenko about embedding and how people latch on to the first bit of information that they're offered while ignoring anything contradictory. This causes the duo to realize that [[spoiler:they've been basing their whole investigation on Captain Dickson's briefing that the victim was buying the drugs when in truth she was the one ''selling'' them]].

* Generally speaking, fanworks [[FandomSpecificPlot/MiraculousLadybug frequently present this]] as a major issue with Alya. Once she's drawn a conclusion, she digs her heels in and defends it. This naturally tends to get amplified in [[AccusationFic Salt Fics]] set after the events of "[[Recap/MiraculousLadybugS03E01Chameleon Chameleon]]", reaching IRejectYourReality levels at times; it doesn't matter how much hard evidence she's presented with, she simply won't (or ''can't'') admit that she was wrong.

* After she's replaced in ''Fanfic/BurningBridgesBuildingConfidence'', Alya immediately leaps to the conclusion that Vexxin must have ''stolen'' the Fox Miraculous, quickly banging out a blog post accusing the new heroine of being a thief. When Lila spins her own sob story about what supposedly happened, Alya's willing to listen since she's '[[CelebrityLie Ladybug's friend]]'... but it's not long before her anger gets the better of her, and she dismisses everything that doesn't support her belief that Vexxin ''must'' have stolen the Fox.
** This is effectively Alya's FatalFlaw: despite claiming that 'a good reporter always checks her sources', in ''practice'', [[{{Hypocrite}} she sees no need to do so once she's set her mind on something]]. This makes her an ideal pawn for [[ManipulativeBitch Lila]], who transforms her from [[WeUsedToBeFriends Marinette's best friend]] to [[TheHeavy her personal one-girl attack crew]].
** This flaw is prominent in many other [[Recap/MiraculousLadybugS03E01Chameleon Post-"Chameleon"]] [[AccusationFic Salt fics]] where Alya is presented with hard evidence against Lila's lies and her own erroneous theories but she doesn't believe it.
* Henrietta Garland from ''Fanfic/CatarinaClaesMustDie'' is the reincarnation of a bullied girl that found relief watching ''[[FictionalVideoGame Fortune Lover]]'' HateSink bully Caterina Claes die in the bad ends. So when she is reincarnated in the world of ''Literature/MyNextLifeAsAVillainessAllRoutesLeadToDoom'', she remains firmly convinced that Caterina is a villainess who should end in doom, despite evidence that Caterina is now a NiceGirl thanks to regaining memories of her past life. For example, when hearing how Caterina is treated like a beloved [[ClassPrincess Saint]], Henrietta is convinced that she is really a BitchInSheepsClothing that secretly bullies her adopted brother Keith and the commoner student Maria when in actuality the latter two are among Catarina's loved ones.

* ''Webcomic/FeralnetteAU'':
** This is one of Alya's {{Fatal Flaw}}s, something which Lila has gleefully {{Exploited|Trope}} in order to turn her against Marinette. While she gets called out on it several times, Marinette drives the point home during a confrontation in ''Birds of a Feather'':
--->'''Marinette:''' ...There was a time not long ago where you demanded to know why I changed, and whether or not I was as terrible as Lila claimed I was. I didn't want to talk about Lila. I just wanted to hang out with you, because I'd just gone through something unimaginably cruel and painful. You took my silence on the topic as ''guilt''. You wouldn't drop it. You insisted on answers, so I lashed out, wanting space. I didn't want to think about some stupid, vapid drama. I didn't want to think about Lila. ''I didn't want to think about '''anything'''''.\\
You left. That's fine. But you left, and you decided on your own terms that my reaction was proof of some insane lie rather than a cry for help. That's when I started to realize, there really wasn't anything I could say or do that would change what you thought of me. That's fine. I don't intend to try.\\
''(later)''\\
'''Alya:''' Marinette, if you had just told me you were going through some sort of a crisis, I wouldn't have--\\
'''Marinette:''' ''[[ArmorPiercingQuestion So it's my fault again?]]''
** The DramaticIrony of this is that ''Marinette herself'' has fallen into the same mental trap as Alya. Having drawn the conclusion that it's pointless trying to convince Alya or anyone else that she's not the {{Jerkass}} Lila has [[MadeOutToBeAJerkass made her out to be]], she's convinced herself that none of her former friends ''care about her anymore''. So Alya's AngerBornOfWorry is miscontrused as her going on the attack ''again'', assuming the worst of her ''like she always does''.
* Flat out {{Lampshade|Hanging}}d in ''Fanfic/GirlDays'' where [[Manga/RanmaOneHalf Kunou, Ryouga, and Mousse]] are all mentioned to "take the facts and jam them into their viewpoint".
-->[[LemonyNarrator Author's Note]]: The astute reader will notice that Ryouga Hibiki has what can be best described as an unusual logic system. Rather than going from facts to conclusion, [[SharpshooterFallacy one starts at the conclusion and jams the facts around it]]. And in the minds of the likes of Ryouga Hibiki and Tatewaki Kunou, [[NeverMyFault we all KNOW what the conclusion is]].
* ''Fanfic/TheGiwMeetsItsMatch'': The Guys in White are so convinced that ghosts are AlwaysChaoticEvil and non-sapient that they ignore all evidence to the contrary, relying upon {{Doublethink}}-laden "logic" to justify their stance. They also firmly believe that it's outright ''impossible'' for anyone who isn't a ghost to oppose them, as their cause is so "obviously righteous"; thus, they assume anyone who resists their extremism is either a ghost in disguise or secretly being controlled by one.

* Invoked in ''Fanfic/LostInCamelot'', when Arthur learns that Bo, Merlin, and Morgana are in a triad relationship and ask how they intend to keep their relationship secret from Uther. Since Uther believes that Morgana's involvement with Bo is basically just them indulging a youthful interest, and he is also convinced that Merlin is involved with ''Arthur'', Morgana doubts that Uther will properly register anything that contradicts that perspective for a while at least.
* ''Fanfic/TheMoonCriesInReverseNaruto'': PlayedForDrama in ''Lunar Lamentations''. Once Anko got it into her head that Naruto, Sakura and Shikamaru might not be too terribly loyal to Konoha due to how badly Naruto and Sakura were bullied and [[IntelligenceEqualsIsolation Shikmaru's intelligence reminding her too much of Orochimaru]], she views literally ''everything'' her genin team does as "more evidence" of how dangerous they are. Even worse, Ibiki and Hiruzen share her beliefs, leading them to extreme ends to try and nip the supposed issue in the bud... and potentially creating a SelfFulfillingProphecy in the process.
* In ''Fanfic/PokemonShadowOfTime'', Ash has rejected the idea of dating any of his travelling companions because he doesn't want to abandon them like [[spoiler:he believes]] his father did, ignoring how even his Pokémon are aware that the girls would be willing to follow him on his travels.
* ''Fanfic/RainbowDoubleDashsLunaverse'': The Element Bearers are utterly incapable of seeing Corona (also known as [[spoiler:Celestia]]) as anything but an arrogant, cruel, greedy monster who'd kill them all given half a chance. This backfires when they're [[EnemyMine forced to work together]], and the six of them think backstabbing the PhysicalGod who's agreed to work with them is a better idea than stopping the necromancer who's trying to become immortal. In fairness, though, they're part of a culture that's been fed a thousand years' worth of stories about how evil she is, and when they first met, she kidnapped some of their loved ones, on account of being completely insane. But even after she's cooled down somewhat, they still refuse to think she's not pure evil.

** This flaw is prominent in many other [[Recap/MiraculousLadybugS03E01Chameleon Post-Chameleon]] [[RevengeFic salt fics]] where Alya is presented with hard evidence against Lila's lies and her own erroneous theories but she doesn't believe it.

* Flat out [[LampshadeHanging lampshaded]] in ''Fanfic/GirlDays'' where [[Manga/RanmaOneHalf Kunou, Ryouga, and Mousse]] are all mentioned to "take the facts and jam them into their viewpoint."

* In ''Fanfic/InfinityTrainWakeMeUp'', there's something of a running theme of characters coming to a conclusion about how other people are or "should be," and treating them accordingly no matter the evidence.

** Eventually, this becomes a major plot point: the [[spoiler:[[BigBad Vermillion Citadel's]]]] motive is born out of the belief that Chloe Cerise ''must'' be one of the Train's greatest heroes. Being [[spoiler:[[AllianceOfAlternates composed of "Chloes" from across the multiverse]]]], they (ironically enough) have a ''checklist'' of traits that they believe "Chloe of the Vermillion" must possess. They are willing to resort to kidnapping, blackmail, and [[SuperheroParadox tormenting innocent people]] just to push Chloe into becoming a famed hero- only for most of their plans to fail because [[SpiritualAntithesis this Chloe]] is a ''lot'' [[TruerToTheText closer to her anime incarnation]]. She is ''not'' a NightmareFetishist, being ProperlyParanoid at someone handing her a "demonic artifact," is actually [[WhyDidItHaveToBeSnakes afraid of dogs]], and hence never traveled with Atticus, and while she was [[JumpedAtTheCall eager to transform with a Miraculous]], she does about as well against a rampaging monster as you might expect from a ten-year-old with no combat training.

* ''Manga/DeathNote'': [[VillainProtagonist Light Yagami]] is firmly convinced that he's a good guy and that everything he does as Kira is necessary to [[UtopiaJustifiesTheMeans create a better world]], and refuses to see that his actions [[HeWhoFightsMonsters make him no better]] than the criminals he's trying to rid the world of. [[CantTakeCriticism Heaven help you]] if you so much as ''suggest'' that what Light is doing is evil.
* ''Anime/DragonBallSuper'': As far as Zamasu is concerned, ''all'' mortal life is evil and needs to be destroyed, and the gods, while [[TheGodsMustBeLazy lazy]], are inherently perfect. He blindly refuses to consider the possibility that mortals can learn and grow from their mistakes and that [[GodIsFlawed the gods are just as fallible]], even when Gowasu tells him as such.

* In the ''WesternAnimation/GravityFalls'' episode "[[Recap/GravityFallsS1E11LittleDipper Little Dipper]]" after [[Characters/GravityFallsMabelPines Mabel Pines]] determines that Dipper's spontaneous growth spurt is the result of magic, she accuses him of hiding a wizard in the closet. After she opens the door to find an empty closet, she accuses him of hiding an ''invisible'' wizard in the closet. Even after Dipper shows her what the real cause of his growth spurt was (a flashlight fitted with a magic crystal that refracts light into growth and shrink rays) she still thinks there's an invisible wizard hiding in the closet.

* Played for tragedy in ''Manga/YourLieInApril''. Early on, it is shown that Kousei's late mother Saki once beat him bloody for underperforming at piano, causing him to wish she was dead. Later, we see the same event from her point of view, where she confesses to a close friend that she pushed him to abusive extents because she was terminally ill and convinced that piano mastery was the only way he could make a living after her passing. Whether this puts a sympathetic sheen on a secretly-broken woman's tough love or just makes her more monstrous for being blind to any other ways Kousei could have gotten by remains one of the divisions in the fandom.

* ''Manga/{{Bleach}}'': As Ichigo and Aizen face off in their final battle, Aizen is convinced that Ichigo has discarded all of his power in exchange for raw physical strength due to the fact that he can't sense his Reiatsu. But as Ichigo begins to NoSell Aizen's attacks and overwhelm him, Aizen starts making more and more excuses to convince himself that Ichigo surpassing him is a mere fluke, to the point that Aizen outright gives up on trying to understand Ichigo under the notion that he's no longer worth understanding. It takes Ichigo unleashing the [[DangerousForbiddenTechnique Final Getsuga Tenshou]] and visually ''oozing'' with power before Aizen realizes that Ichigo ''did'' surpass him, and that the reason he can't sense is Reiatsu is the same reason no one else can sense Aizen's: Ichigo has reached a new dimension of power that completely eclipses his own. [[ThisCannotBe He doesn't take it well.]]

* Henrietta Garland from ''Fanfic/CatarinaClaesMustDie'' is the reincarnation of a bullied girl that found relief watching ''[[FictionalVideoGame Fortune Lover]]'' HateSink bully Caterina Claes die in the bad ends. So when she is reincarnated in the world of ''Literature/MyNextLifeAsAVillainessAllRoutesLeadToDoom'', she remains firmly convinced that Caterina is a villainess who should end in doom, despite evidence that Caterina is now a NiceGirl thanks to regaining memories of her past life. For example, when hearing how Caterina is treated like a beloved [[ClassPrincess Saint]], Henrietta is convinced that she is really a BitchInSheepsClothing that secretly bullies her adopted brother Keith and the commoner student Maria when in actually the latter two are among Catarina's loved ones.

* In ''VisualNovel/AceAttorney'', Miles Edgeworth's initial approach towards prosecuting was this. Unlike other prosecutors who merely wanted to win (such as his mentor Manfred von Karma), or those who only want to seek the truth (such as Klavier Gavin), Edgeworth worked on the premise that the defendant was ''always'' guilty of the crime they were accused of, and prepared his cases and arguments around that. [[spoiler:He thinks this way because of PsychologicalProjection; he believes that he is a KarmaHoudini for accidentally killing his father as a child and assumes that all other defendants are in the same position he was: guilty but faking innocence]]. His character arc in the original game involves getting over this view; it starts to crack in case 1-3 when Phoenix convinces him that Will Powers was innocent and [[spoiler: Dee Vasquez]] was suspicious, and Edgeworth ends up being the one to force the critical testimony that ends the case in a Not Guilty verdict, and it falls apart entirely after he becomes the defendant of 1-4 [[spoiler:and Phoenix proves that not only is he innocent of the original crime, he never killed his father, and Manfred von Karma taught him to believe in his own guilt because ''Manfred'' was the true murderer.]]

* ''Series/EretzNehederet'': In [[https://www.youtube.com/watch?v=gHTNuBKtzHc this skit]] mocking the Creator/BBC's reporting on the Israel-Hamas War, the BBC reporter and newscaster believe anything bad must be Israel's fault, and they twist themselves in knots trying to justify this view despite evidence to the contrary. When a recording of a Hamas operative outright says "it was us who bombed the hospital", the BBC says "I guess we'll never know the truth, even when the Hamas members repeatedly claim credit.

Theory Tunnel Vison can be both positive and negative, and the person suffering from it can be proven right in the end. The key point is that someone who suffers from it will [[SelectiveObliviousness discard any and all evidence]] that proves them wrong, no matter how solid it is.

* In the ''Series/{{Elementary}}'' episode “The Deductionist”, FBI profiler Kathryn Drummond notes that she has profiled various serial killers and found them all to be the victim of childhood sexual abuse. However, this led to her forming the same view of killer Martin Ennis, to the extent that she paid an old neighbour of the Ennis family to provide fake testimony confirming such abuse rather than just admit that she was wrong about him, which drove Ennis’s father to suicide and his mother dying of despair a year later.

* The {{ComicBook/Daredevil}} comic "Seventh Circle" has him run into ComicBook/ThePunisher during a Russian gangster's high-profile trial that Matt Murdock is trying to move to Texas since it'd be impossible for the gangster to get a fair trial in New York. Frank is convinced Matt is trying to get the trial held in a state where the death penalty applies and calls Matt a killer, one using a jury rather than a gun... [[DramaticIrony to Daredevil]].
* ComicBook/DoctorDoom simply cannot get it out of his head that Reed Richards was responsible for the accident that disfigured him. Being something of an egomaniac, he naturally assumes Richards thinks like him, and occasionally designs traps that would be impossible for Doom to escape... and that Richards just strolls out of.
* Hugo Strange projects his many, ''many'' neuroses onto ComicBook/{{Batman}}, certain that he only fights crime because he gets off on beating weaker people (Strange being a short, glasses-wearing psychiatrist who occasionally dresses as Batman).
* J. Jonah Jameson is convinced that Franchise/SpiderMan is a threat and a menace, and no matter how many acts of heroism Spider-Man performs, nothing will change his mind. One story shows that his distrust comes from his abusive upbringing by his veteran father, which soured him on the idea of heroes.

* The reason Lex Luthor has never figured out ComicBook/{{Superman}}'s secret identity and never will barring certain extreme circumstances (such as at the end of ''ComicBook/TheBlackRing'' where he became omnipotent and was able to view Supes' past) is because he is absolutely ''certain'' that [[EvilCannotComprehendGood Superman is an evil mastermind]] [[PsychologicalProjection just like him]], who would never bother wasting time with being an ordinary journalist like Clark Kent. One comic has him hire a computer expert who uses facial recognition software to point out the obvious ClarkKenting. Lex responds by firing her because ''obviously'' Superman wouldn't "stoop" to being Clark Kent and so her software must have something wrong with it.

* ''Fanfic/RainbowDoubleDashsLunaverse:'' The Element Bearers are utterly incapable of seeing Corona (also known as [[spoiler:Celestia]]) as anything but an arrogant, cruel, greedy monster who'd kill them all given half a chance. This backfires when they're [[EnemyMine forced to work together]], and the six of them think backstabbing the PhysicalGod who's agreed to work with them is a better idea than stopping the necromancer who's trying to become immortal.

* ''WesternAnimation/TheOwlHouse'': Despite having lived among them for hundreds of years, [[spoiler: [[Characters/TheOwlHouseEmperorBelos Emperor Belos]] still clings to the belief he was fed during his childhood, that witches and demons are all inherently evil and deserve to die. This is especially galling since the residents of the Boiling Isles were actually fairly peaceful and good-natured when he first arrived and only turned more callous and darwinistic ''because'' of his influence. Likewise, he preemptively rejects the idea that other humans (like Luz or Caleb) could and would have genuine objections to his goal of ''[[FinalSolution complete genocide]]'', convincing himself that living among witches has twisted them somehow, and justifying the fact that he murdered Caleb by saying that he was trying to save his soul.]]

** General Zod theorizes that Jor-El sent his son to Earth so that he would become a god among the humans, turn the planet into a New Krypton, restore the glory of the Kryptonian race and bring then to galactic supremacy (something Zod himself would've done, of course, [[SuperSupremacist militant jingoist that he is]]). Seeing that Superman has "failed" in this endeavor, Zod swears to succeed where he failed and prepares to have Superman executed by a [[MoreThanMindControl brainwashed]] Superboy.

** During the season 4 finale, after the Zods fail to conquer the Earth or kill either of the Els, Lor Zod uses the [[TimeMachine Time-Sphere]] to flee before he can be captured by the Justice League or their allies. Much to his surprise, the Time-Sphere's controls are locked, meaning Lor has no way to know where or when he's headed to. Once the Time-Sphere reaches its destination, Lor finds himself back on Mars, six months ago, mere moments before Ma'alefa'ak's gene bomb explodes. As Lor finds Superboy attempting to destroy the gene bomb by sinking it into the lava flow, he determines that [[MakeWrongWhatOnceWentRight he's been given one last chance to kill Superboy]] and doesn't stop for even one second to ponder how or why he's been brought back to this moment specifically. [[spoiler:This proves to be a fatal mistake as the Time-Sphere disappears as soon as Lor steps out of the cockpit, distracting him from killing Superboy before Phantom Girl accidentally takes him to the Phantom Zone and leaving him with no time to escape before [[HoistByHisOwnPetard the kryptonite-laced bomb explodes]], [[StableTimeLoop killing Lor and etching his shadow on a nearby wall as he's reduced to ash]].

** [[ChildProdigy Amanita]] was not impressed when [[AbhorrentAdmirer Parker]] began flirting with her shortly after they met. She promptly handed him an Eevee as a blatant bribe to go away and doesn’t bother [[InsufferableGenius hiding her disdain]] going forward. At one point, she expresses sincere sympathy for Jinny when she learns that the other girl was having a sleepover with [[CasanovaWannabe Parker]]. In actuality, Parker is a perfectly friendly five-year-old and hasn’t been shown flirting with anyone except Amantina.
** Blake and Whitley actually have something of a ''mutual'' example going. Blake is [[InspectorJavert absolutely determined]] to arrest Whitley based on her [[AmbiguousCriminalHistory past as a Team Plasma member]], with no regard for what she’s done to [[TheAtoner try to atone]] in the intervening years. In the process, he makes himself look like such a ''jerk'' that Whitley [[JerkassToOne holds him in contempt]], and Trip chose to interfere with his ambush [[HateAtFirstSight five minutes after meeting Blake]], without considering that the [[GoodIsNotNice Interpol agent]] ''might'' [[JerkassHasAPoint have decent reasons to arrest Whitley]].
** Eventually, this becomes a major plot point: the [[spoiler:[[BigBad Vermillion Citadel’s]]]] motive is born out of the belief that Chloe Cerise ''must'' be one of the Train’s greatest heroes. Being [[spoiler: [[AllianceOfAlternates composed of “Chloes” from across the multiverse]],]] they (ironically enough) have a ''checklist'' of traits that they believe “Chloe of the Vermillion” must possess. They are willing to resort to kidnapping, blackmail, and [[SuperheroParadox tormenting innocent people]] just to push Chloe into becoming a famed hero- only for most of their plans to fail because [[SpiritualAntithesis this Chloe]] is a ''lot'' [[TruerToTheText closer to her anime incarnation]]. She is ''not'' a NightmareFetishist, being ProperlyParanoid at someone handing her a “demonic artifact,” is actually [[WhyDidItHaveToBeSnakes afraid of dogs]], and hence never traveled with Atticus, and while she was [[JumpedAtTheCall eager to transform with a Miraculous]], she does about as well against a rampaging monster as you might expect from a ten-year-old with no combat training.

Everyone has their own view of the world and what happens around them. Maybe Bob believes that HumansAreBastards. Maybe Alice thinks Chris is going to betray her. Given enough time, though, these views and opinions can change, allowing Bob to see the good in people, and Alice to start to trust Chris. This trope is when that never happens; A character suffering from Theory Tunnel Vision will stick with whatever idea he or she has for way longer than what would be normal. Even if Bob meets hundreds of {{Good Samaritan}}s, he'll keep stating that HumansAreBastards and Alice will never trust Chris even though he saved her life several times now.
