This character picks on the short girl for being short. He'll ask a woman for her age. He'll bug the [[AmbiguouslyGay flamboyant guy about his sexuality]]. And the worst part is, he doesn't realize what he's doing is rather painful for the person on the receiving end of the criticism. In the worst cases, [[DiggingYourselfDeeper he might not stop at one insult]] and even continue until someone [[MegatonPunch forces him to stop]], or the other person runs away crying. (His reaction to this is probably: "Huh? What did I do?")

What separates him from the {{Jerkass}} is that this person is actually a good guy - he's just clueless to things that people might generally be sensitive to. To him, it was just a [[JustJokingJustification fun joke]] or an [[BrutalHonesty honest assessment]] - no offense intended. When others bring up the fact that what he's saying is hurting other people's feelings, he tries to change.

The IdiotHero is prone to this. They tend to receive replies like YouKnowImBlackRight and ImStandingRightHere. InnocentBigot is a subtrope. When this is done intentionally, they're a DeadpanSnarker. Obviously guilty of frequently committing a FeeFiFauxPas. It may also be the result of a CrazyCulturalComparison or a CrossCulturalKerfuffle. Compare HorribleJudgeOfCharacter and ObliviousMockery.

A frustrating TruthInTelevision. Especially notable are people with UsefulNotes/AspergerSyndrome, though this can vary and often the exact opposite is true if said people are ''[[SensoryOverload hypersensitive]]''.


[[folder: Anime and Manga]]
* Goku from ''Manga/DragonBall''. Though it's implied that he had brain damage as a baby due to hitting his head, and not to mention he was almost totally isolated from others until he was 12.
** Maron, a filler character, in the Garlic Junior Saga, is this when she insults Chi-Chi and Bulma by calling them old ladies (and you can guess how the former reacts).
** Little Marron, Krillin & Android 18's daughter, also qualifies. In a scene in the Great Saiyaman Saga, when Master Roshi asks if he wants to participate in the tournament, she replies with "No way, you're too old!!". For Marron, this is a JustifiedTrope, as she is only 3 years old and she doesn't know any better.
* ''Manga/OnePiece'': Monkey D. Luffy's ability to do this is legendary. While in the tower of the ShrinkingViolet mermaid princess, he starts eating her food while she talks to him. His mouth is filled with food, so his cheeks bulge out. This is new to the innocent girl, so she pokes his cheeks, and he shouts at her for it. She begins to well up with tears, and he calls her a coward, a crybaby, and says in a completely happy, joking manner, "I don't like you one bit!". He obviously thought he was bantering, since the next thing he says is to suggest she sneaks out of the room to go on an adventure, in as happy and joking a manner as before.
* Takanashi from ''[[Manga/{{Working}} WORKING!!]]''.
** Yachiyo is like this, usually to Satou.
** Yamada has her moments too.
* Manga/InuYasha has his moments. [[JustifiedTrope Justified]], since he is a half-demon and was treated rudely by humans and demons, decided to live isolated from others and hence doesn't know when something can be seen as rude.
* Manga/InuYasha's spiritual predecessor [[Manga/RanmaOneHalf Ranma Saotome]] occasionally had moments of this, too, but was just as likely to either be retaliating for something rude done to him, or deliberately being rude [[JerkAss just for the hell of it]].
* Ayu from ''Manga/SevenSeeds'' can have shades of this. She calls people "resistant as cockroaches", but means it in the nicest way of a compliment. She decides on a group-split-up that leaves her with someone that she is implied to have a crush on and doesn't get it why people react strangely about it. It isn't until Tsunomata points out to her that her straightforward ways can be seen as hurtful that Ayu even wonders ''why'' it would seem hurtful.
* Sai from ''Manga/{{Naruto}}'' post-HeelFaceTurn and CharacterDevelopment. He is trying to become better friends with Naruto and Sakura, but genuinely thinks "ugly" is a good idea for a nickname, and that people [[BrutalHonesty always need to hear the truth]].
* Miyako in ''Manga/HidamariSketch'' does this a lot. It's hard to be sure when she's just oblivious and when she actually ''is'' winding up Hiro.
* An episode of ''Anime/DigimonAdventure'' was focused on Mimi getting into trouble after she got upset at Izzy, who ignored her in favour of working on his laptop. He had no idea why she was crying, or that he'd been ignoring her at all.
* Haru from ''Anime/{{Tsuritama}}'' who tries to cheer up Yuki about his grandmother's hospitalization by telling him that everyone dies at some point. This is because Haru is a possibly immortal alien who struggles with understanding things from the viewpoint of us PunyEarthlings.
* Bossun from ''Manga/SKETDance''.
* Touma Kamijou from ''LightNovel/ACertainMagicalIndex'' says it's ridiculous that so many people think he's attracted to girls like Index or Mikoto because they're just kids (he's 17, they're 14). While he's trying to say he's not a pedophile, [[ObliviousToLove he doesn't understand that they're genuinely and completely in love with him]], and he doesn't understand that [[ACupAngst implying they have small boobs]], are not beautiful and sexy (instead of pretty and cute), are short, etc. are their biggest {{Berserk Button}}s.
* Mashiro of ''LightNovel/SakurasouNoPetNaKanojo'', who is an IdiotSavant, has NoSocialSkills, [[WordOfDante and is seen by most viewers]] as [=autistic=], runs into this in a close to OnceAnEpisode frequency.
* ''VisualNovel/HigurashiWhenTheyCry'': Keiichi does a minor variation towards Mion in the Watanagashi arc, by not giving her the doll he won, reasoning that she's too boyish to appreciate it as Rena (who [[ImTakingHerHomeWithMe takes home anything she finds cute]]) would; this instance of his calling out her boyish traits (unlike most other times) deeply hurts her feelings. In the original Visual Novel, Keiichi has to get lectured by both Rena and Shion before he finally realizes what he did.
* Masao from ''Manga/{{Shiki}}'' is mostly just a JerkAss, but there's many scenes where he comes off this way too.
* PlayedForDrama in ''Manga/KotouraSan'', when this trope, combined with {{telepathy}} that Haruka [[PowerIncontinence couldn't turn off]], causes her to inadvertently start blurting out her friends' and family's personal secrets, resulting in her schoolmates labelling her as a freak and compulsive liar and [[ParentalAbandonment her parents' divorce]]. Although later on she ''invokes'' this trope [[JerkassFacade to keep people from being close to her]].
* Setsuna in ''Manga/MahouSenseiNegima'' tends to act far too formally and subserviently towards those she feels have a higher social class than her. For example, she always refers to her love interest as ojou-sama/milady and acts more like a servant than a friend. Konoka, for her part, keeps telling her to quit it to no avail. Near the end of the manga, she actually makes Asuna cry by acting even more subservient towards her than she does towards Konoka after Setsuna learns [[spoiler:Asuna is actually a princess]]. Normally, she's Setsuna's best friend, which makes it quite painful to be treated like that. It was a slight exaggeration of how she really felt, but she wanted to make sure Setsuna cut it out immediately rather than make a habit of it.
* Ian in ''Manga/ACruelGodReigns'' does this to Jeremy when he actively tries to make their new step-family a happy one. What he doesn't know is that his father is sexually abusing Jeremy every weekend when they come home from their boarding school.
--> '''Ian''': The plan is to make this a loving household of Lynn Forest, aiming to create a peaceful family.
--> '''Jeremy''': Will it all...work...out?
--> '''Ian''': We'll make it work Jeremy! And in the end we'll all be happy.
* In ''Anime/GirlsUndPanzer'', when Ami, temporary tankery instructor for Oarai, sees Miho among the assembled students, she points out that Miho's mother (Ami's tankery instructor) has done quite a bit for her, makes a polite inquiry about how Miho's sister is doing, and says the Nishizumi school has a long history. Despite having no ill intentions toward Miho, Ami ends up upsetting Miho by bringing up her family (Miho, unable to adhere to her family's SecondPlaceIsForLosers mentality, had until recently quit tankery), but Saori quickly moves to ChangeTheUncomfortableSubject.
* In ''Anime/PuellaMagiMadokaMagica'', Sayaka is this to Kyousuke, the object of her affections. Kyousuke's passion is the violin, so [[CareerEndingInjury his arm getting paralyzed in an accident]] was a big blow to him. Rather naively, Sayaka thinks bringing him classical music [=CDs=] would relax him. [[BerserkButton She was wrong]][[note]]because it was all music he couldn't play[[/note]], and it sends him into tears at first and into an almost screaming HeroicBSOD later.
** Incidentally, Kyousuke ''also'' counts as this. While he cares for Sayaka, it's more in a PlatonicLifePartners sense and he's completely [[ObliviousToLove oblivious to Sayaka's love]]. This results in him doing things that, unbeknownst to him, really hurt Sayaka and was partly her [[spoiler:UnwittingInstigatorOfDoom]] (the spoiler is a trope, so don't hover over it).
* Saya of ''Manga/ServantXService'' tends to speak her mind without even considering the potential consequences. Particularly evident in Episode 6, where she unwittingly sent the normally carefree Yutaka into a CornerOfWoe by passively saying that he's beneath her, and a flashback reveals that she rejected a boy's confession by saying he should've looked at himself in a mirror and thought again (she meant she thought he could do better). Eventually Chihaya had to warn her against rejecting Mrs. Tanaka's offer of marriage to her grandson so as not to cause ''heart attacks''.
* Nia in ''TengenToppaGurrenLagann'', due to her sheltered upbringing. She is completely oblivious to any negative mood, which doesn't endear her to the others, especially after [[spoiler: Kamina had just recently died]]. She also cheerfully [[spoiler: turned down Simon's proposal]]. Fortunately Kiyoh and Kiyal make her realize her accidental mistake.
* In ''Manga/GekkanShoujoNozakiKun'', Seo's {{jerkass}} attitude is seen by Nozaki as a result of being mood-blind. Probably the best example of this is when Seo tells Nozaki that people ask her for help all the time, that she's considerate of others and that she can read situations...all while ruining a group picture, smearing someone's calligraphy and interrupting a love confession, in that order. However, the rest of the time it's hard to tell whether she really is this trope or genuinely a {{jerkass}}.
* An IdiotPlot climax of ''LightNovel/SeikokuNoDragonar'' starts purely because [[CloudCuckooLander the airheaded maid Plum]] mutters a racist comment that [[InterSpeciesRomance a dragon and a human can't get married]]. Eco, who's a hypersensitive {{Tsundere}}, launches herself out of the castle in despair and ''right into the enemy's hands''.
* When Loki Asgard transfers into the main characters' class in ''Manga/BokuGirl'', her first act upon seeing the [[DudeLooksLikeALady androgynous Mizuki]] is to remark on how girls are allowed to wear the boys uniform. This is actually a subversion in that Loki Asgard is ''the'' Loki and is directly responsible for Mizuki being turned into a physical girl, so she knows ''exactly'' what she's saying.
* In ''{{Cute High Earth Defense Club LOVE}}'''s fourth episode, [[{{Keet}} Yumoto]] apologizes to someone for annoying him, addressing him like an older man. The guy is [[YoungerThanHeLooks actually a student from Yumoto's high school]] who's very sensitive about people thinking he's fifty, to the point that [[EvilMentor Zundar]] turns him into a MonsterOfTheWeek with the power of [[FountainOfYouth making people into children]].

[[folder: Comic Books]]
* Because [[NoSocialSkills she lacks social skills]], Laura Kinney aka ComicBook/{{X 23}} tends to do this. After an adventure in Limbo, Laura sees no problem with telling Surge (who wasn't present) that her boyfriend Prodigy had his heart ripped out (he got better) when all the other students were evasive about it (even implied that this was ''why'' Nori asked her about it after the others didn't come clean). When Laura is later attending ''ComicBook/AvengersAcademy'' and {{Wolverine}} brings some of her former classmates from Xavier's there to keep them safe, she greets Dust by telling her she "smells healthy." After Dust reminds her it's not polite to tell someone how they smell, she innocently says that because she can't ''see'' her (Dust practices ''hijab'' and covers herself in public) it's the only way she can tell.
* ComicBook/LoisLane, in her attempts to report on poverty, [[http://www.cracked.com/article_18502_the-5-most-unintentionally-offensive-comic-book-characters_p2.html tended to do this]].
* Klara Prast of the ''ComicBook/{{Runaways}}'' once mistook the X-Men for demons, and on another occasion, mistook Tigra for a prostitute. She's also been on the receiving end of innocent insensitivity; Victor and Chase have used the fact that she was once married as an excuse to talk about sex around her, because she presumably already knows about it. It doesn't occur to them that she'd rather not be reminded of that fact...
* In ''ComicBook/AvatarTheLastAirbenderThePromise'', some of the members of the Yu Dao chapter of the Air Acolytes tattooed their foreheads just like Aang. Who thought they were [[BerserkButton treating his culture as if it was a game]]. The members later apologized, saying they never meant to insult him or his culture.
* In ''{{ComicBook/Violine}}'':
** After crocodiles tear appart two pursuing death squad members, Kombo leads Violine away so she doesn't see it... and then tells her how the crocodiles teared them apart in detail.
** Kombo does the same thing when Violine is in danger from crocodiles herself, describing how they will take pieces of meat to the bottom of the river to let them rot before eating them.

[[folder: Fanworks]]
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fic ''[[http://www.fimfiction.net/story/214290/brother-bothers Brother Bothers]]'', Pinkie Pie is this to Cheese Sandwich [[SiblingYinYang and]] [[GrumpyBear his]] [[DeadpanSnarker brother]] [[JerkassWoobie Tomato]] concerning their nasty SiblingRivalry. She forces them into a "Brotherly Bonding Time", not realizing that it would only aggravate their already tense feud, up to the point where both of the brothers end up exploding at each other. She realizes this at the end of the fic and apologizes to them.
* In ''[[http://www.fimfiction.net/story/174421/hopes-and-follies Hopes and Follies]]'', Twilight assures Trixie that she doesn't have to worry about their past conflicts, because nopony holds her responsible for it and they hardly even remembered the Ursa incident until she came back. It's not until after Trixie storms off overwhelmingly pissed that Twilight realizes that a professional showpony would ''want'' to be remembered, even as a villain. Not to mention that those events were some of the most defining moments of her life. ''And'' Trixie has an overwhelming need to be recognized by Twilight, one way or another. This results in Trixie resolving to become an enemy, rival or problem that Twilight ''can't'' ignore... ironically, while Twilight's resolving to become closer to Trixie and accept her as a friend.
* In "[[Fanfic/TheDearSweetieBelleContinuity Dear Sweetie Belle]]," Rarity had just found out she was pregnant after a party her roommate had dragged her to. Said roommate sees her crying and asks her if she wants to go to ''another'' party. [[NoHoldsBarredBeatdown Rarity freaking snaps]].
* In the ''MorkAndMindy'' fanfic ''FanFic/MorkAndMindysTwentyFifthAnniversary'', Beth jokes that "lately people think Daddy's [Mindy's] son anyway", not realizing that this fact is upsetting to her mother.
* In ''Literature/TheHobbit'' fanfic ''[[http://archiveofourown.org/works/3385085/chapters/7405448 Wear a Flower in Your Hair (You're Beautiful)]]'', Thorin calls Bella a halfling in reference to her being a hobbit. Unbeknownst to Thorin, "halfling" is an insult hobbits use to describe females who are barren.
* In ''Fanfic/DisneyHighSchool,'' [[Disney/TheHunchbackOfNotreDame Quasi]] is occasionally on the receiving end of this.
-->'''[[Disney/TheEmperorsNewGroove Kuzco]]:''' WOW cool costume, that mask is amazing! Are you in the drama club?
-->'''Quasimodo:''' No, it's my face...I look like this.
-->'''Kuzco:''' [[OhCrap Oh shi]]...I'm sorry! I didn't...man I'm sorry!
-->'''Quasimodo:''' [[TheWoobie It's okay, it's not the first time]]...

[[folder: Film - Animated]]
* Fix-It Felix Jr. of ''Disney/WreckItRalph'' has this painfully so. He can't bring himself to tell the Nicelanders to let Ralph in his birthday party, he accidentally causes Calhoun to suffer a HeroicBSOD when he calls her "one dynamite gal" and only realizes how crummy he's been when Ralph slings back Felix's accusation that he doesn't know how it feels to be treated as a criminal.
* Anna in ''Disney/{{Frozen}}'' is [[LaserGuidedAmnesia made to forget]] the fact that her older sister Elsa has [[AnIcePerson ice powers]] [[spoiler: after the latter nearly accidentally kills Anna while playing with them]]. The fear and guilt force Elsa to [[WhatHaveIDone isolate herself]] for over a decade, which Anna does not understand. So naturally she showers Elsa with [[ArmorPiercingQuestion Armour Piercing Questions]], causing her to break down and flee the castle.
-->'''Anna:''' Elsa, please, I can't live like this anymore!
* Wilbur Robinson of ''Disney/MeetTheRobinsons'' treats Lewis being an orphan as a mere footnote when the audience is aware that this is probably one of the most painful parts, if not ''the'' most, of Lewis's life. Kind of {{Justified}} since [[spoiler:Wilbur knows he's destined to be HappilyAdopted by [[TimeTravelTenseTrouble the end of the day/thirty years ago]]]].
* In ''WesternAnimation/ScoobyDooMoonMonsterMadness'', Fred accidentally offends two astronauts by reminding them that their mission occurred "before [he] was born."
* In ''WesternAnimation/PenguinsOfMadagascar'', even when Private expresses how much he wants just to be a meaningful and valued member of the team, the others continue to just treat him as simply "the cute one", much to his annoyance.
-->'''Skipper:''' You can't take away Private's cuteness!
-->'''Kowalski:''' He's the cute one! That's, that's his thing!
-->'''Private:''' What?
-->'''Skipper:''' It's all the little guy's got!
-->'''Private:''' Ugh...

[[folder: Film - Live-Action]]
* ''Film/ThePurge'': The youngest Sandin kid is asking his parents why they don't kill during The Purge. He thinks it's a game and doesn't quite realize yet that it isn't.
* In ''Film/{{Elf}}'', Buddy meets Miles Finch, a little person. Having grown up with SantaClaus and his elves his whole life, he assumes Miles is an elf and addresses him as one, asking how things are back at Santa's workshop. Miles is enraged, thinking Buddy is doing short jokes. Throughout the whole scene, Buddy doesn't understand his mistake, even after Miles beats him up.
* Mr. Spock of ''{{Star Trek}}'' fame always had a little bit of this going all the way back to the original series, due to his being raised in a society where emotions are suppressed in favor of logic, much to the annoyance of Dr. [=McCoy=] and the others. Captain/Admiral James T. Kirk was usually more patient with Spock due to their HeterosexualLifePartners friendship, but in ''Star Trek IV: The Voyage Home'' Kirk, after putting up with an even more InnocentlyInsensitive than usual Spock (who was still coming off of rebirth) in the 20th century finally loses his temper and snaps at Spock who, upon learning that the window of opportunity to snatch up two whales is rapidly closing (thus placing the future of the Earth in dire peril), bluntly states that their mission won't be successful and states it as if they were running a grocery errand. Specifically Kirk tears into Spock with an incredulous "Our mission? Spock you're talking about the end of every life on Earth! You're half human! Haven't you got any God damned feelings about '''THAT'''?!"
* In ''Film/XMenDaysOfFuturePast'', after Mystique escapes the peace conference, she is outed as a mutant on the news. She manages to get to a hospital and get her leg bandaged in her normal human guise. The nurse who is doing it is watching the earlier footage and pities Mystique's appearance, wondering "It must be hard waking up each day and seeing that in a mirror". Ouch.
* Ahkmenrah's parents from ''NightAtTheMuseum'' when they hear Larry is half Jewish:
--> "We love Jews! We owned forty thousand. So happy, always singing with their candles..."
* In ''Moonrise Kingdom'', Suzy comments that [[ConvenientlyAnOrphan being an orphan must be quite exciting]]. Her friend Sam, an orphan who is conspicuously ''not'' HappilyAdopted, is offended.
-->'''Sam:''' I love you, but you don't know what you're talking about.

[[folder: Literature]]
* In ''Literature/DragonBones'', it is mentioned that Ward pretends to be this as part of his ObfuscatingStupidity. For example, when his uncle asks him whether he knows what just happened (after his father's death), Ward nods, and says "I get father's horse", the stupidest and most inappropriate thing he can come up with at the moment.
* Hermione Granger comes off like this in ''HarryPotter'' at least once a book, arguably downplayed in the movies.
* Princess Eilonwy has moments of this in ''The Chronicles of Prydain'' series.
* Depending on interpretation, Franchise/SherlockHolmes. Opinion varies on whether he's genuinely socially inept or deliberately spiteful to people who aren't as smart as him. The [[Film/SherlockHolmes 2009 film]] favours the latter explanation, but critics who stress Holmes' loneliness as a character trait favour the former.
** The BBC series ''Series/{{Sherlock}}'' seems to use a bit of both - he once asks John whether a comment was too insensitive, but also makes fun of everyone for not understanding his deductions. We haven't seen much of the loneliness outright yet, but he sure does get upset when John's in danger.
** In the BBC series, he is apparently a Sociopath, as well.
*** He ''claims'' to be one, to be sure, but the fact that he shows genuine concern for another human being pretty clearly tells that if he has a disorder, it's not as serious as he thinks. Or perhaps John is just the exception.
** Both presentations may be correct. Individuals with exceptionally high [=IQs=] often have difficulty with proper social interactions, usually coming off as either distant, patronizing, or outright arrogant and insulting (even when it is not their intent). Psychologists think it comes from their altered viewpoint of reality. People with high [=IQs=] easily make intellectual connections and usually have a better understanding of things. But even when they know intellectually that it is due to their high [=IQ=], they can't always grasp why no one else gets it or may be frustrated by how they need to explain "simple" things. For Sherlock, who likely has a very high [=IQ=], he doesn't get why everyone else can't see the world the way he does. To him, he is pointing out things on the same level of obviousness as "The sky is blue" and then dealing with people who are so dense they need it spelled out to them (even though no one else would ever make those connections).
* BrainlessBeauty Christine from the ''Literature/{{Discworld}}'' book ''Discworld/{{Maskerade}}'', an opera hopeful with the looks but [[DreadfulMusician not the musical talent]], is apparently oblivious to the fact that her very presence is trampling over the ambitions of FatGirl Agnes Nitt, who has the musical talent but not the looks. She also says at one point that Agnes is [[ComplimentBackfire lucky about not having to watch what she eats]].
* Gray Wing from ''Literature/WarriorCats'': ''Dawn of the Clans'' tries (poorly) to comfort Wind Runner by saying that her son Emberkit was in a better place. This, however, makes Wind Runner angry at him, yelling at him that the best place for a kit was at its mother's belly and wishing him grief, saying that he's as bad as Clear Sky and she'll throw that comment back at him. But when [[spoiler:Turtle Tail dies]], she apologizes to him.
* In ''Literature/TomcatBlueEyesDiaries'', Blue Eyes and White Whiskers Rusty go to visit their mutual friend, cat Green Eyes who has just had babies. Blue Eyes is always very friendly, affectionate little tom-cat -- almost a kitten himself. He says to Whiskers that Green Eyes' babies are real ugly and- the horror- even blind. Green Eyes gets angry and swats him twice with her front paws and runs away with her babies. Whiskers tries to explain to him that every mother is sorry when somebody shames her children and tells Blue Eyes that he was not prettier when he was born. Blue Eyes doesn't believe him and is sure that that he was never blind.
* ''[[Literature/MercyThompson Alpha and Omega]]'':
** Asil makes a crude remark about Charles 'sharing' Anna. Because Asil has only known her for a few minutes, he is unaware that Anna is a gang-rape survivor.
** Charles asks Asil how torture affects an Omega werewolf- just before remembering that Asil's wife was tortured to death. (He apologizes later.)

[[folder:Live-Action TV]]
* ''Series/TheBigBangTheory'':
** Sheldon doesn't always realize that he's being condescending about others' intellect.
** His mom is this in another way. Mrs. Cooper is the type of Born Again Christian that would be likely to tell someone YouAreACreditToYourRace or use an outdated, racist term (Leonard eventually has to make her a list of what she can't say). That said, she's so sweet and comforting (unlike her [[InsufferableGenius son]]) you know she doesn't mean anything by it, it's just a side effect of being born and raised in East Texas.
** Amy also tends to fall into this.
* Liz Lemon during high school, as revealed in the ClassReunion of ''Series/ThirtyRock''. (More rarely, she does this in the present as well.)
* Rimmer from ''Series/RedDwarf'' is a more obnoxious variant - yes, he's a pain in the neck, but most times he thinks he's genuinely doing the right thing. Even if he does have ManipulativeBastard moments. Cat's a more straightforward example. Actually, you could just shove ''everyone'' in this category, they all have their moments.
* Mr. Pither from ''Series/MontyPythonsFlyingCircus'' (he's on a cycling tour of North Cornwall). He's a perfectly kindly soul, but oblivious to other people's feelings.
* ''Series/{{Monk}}''. His HyperAwareness lets him in on all sorts of details about people, and he's not always clear on which ones are better to keep to himself, such as when he sees the date on a woman's credit card and realizes she's lying about her age, or deduces that the judge at a hearing has been having an affair with his secretary.
* On ''Series/{{MASH}}'', aristocratic Major Charles Emerson Winchester percieves himself as more intelligent and refined than the rest of his fellow comrades, that sometimes he doesn't realize he offends people in doing so.
--->'''Charles:''' Relax? Are you insane? How would you feel if your sister were marrying a swarthy, dark-haired, olive picker?\\
'''Klinger:''' She did! And for your information, Major, so did my mother and my grandmother, not to mention the future Mrs. Max Klinger, whoever she is! (''storms out in huff'')\\
'''Charles:''' Did I say something to offend him?
* Much of the cast of ''Series/{{Friends}}'' at one point or another, but especially [[{{Cloudcuckoolander}} Joey and Phoebe]].
* Sherlock Holmes has a big moment of this in the second episode of ''Series/TheAdventuresOfSherlockHolmesAndDoctorWatson'', during the scene with Watson's pocket watch. Brilliant as Holmes is, he hadn't anticipated that discussing Watson's ill-fated alcoholic brother might upset him.
** This scene is, of course, lifted from Doyle's ''The Sign of Four'', where Watson is so upset he actually accuses Holmes of secretly investigating his family just so he could show off pretended deductions. Holmes immediately realizes how insensitive he's been and apologizes, and also explains the evidence that led him to his deductions.
* Also Sherlock from BBC's ''Series/{{Sherlock}}''. He tends to [[SherlockScan deduce things]] and think he's being kind by letting the concerned parties know: telling Molly that Jim (her boyfriend) is gay, informing Mrs. Hudson that her love interest is married and a [[TheCasanova casanova]], deducing presents people give him when he's hardly touched the package, etc. He eventually begins to rely on John to give him a heads-up when he's gone too far.
-->'''Sherlock:''' (''after asking why a woman would continue being upset about her daughter's stillbirth a decade ago'') Ah... Not good?\\
'''John:''' Bit not good, yeah.
%%* Abed from ''Series/{{Community}}''.
* ''Franchise/StarTrek'':
** ''Series/StarTrekTheNextGeneration'': Mr. Data, being an android, is often insulting without meaning to be. In ''Liaisons'', he gives Worf advice on dealing with a fractious diplomat who's visiting ''Enterprise'':
--->'''Data:''' I have heard that in moments of diplomatic tension, it is often helpful to find elements of commonality.\\
'''Worf:''' Ambassador Byleth is demanding, temperamental, and rude!\\
'''Data:''' (''sincerely trying to be helpful'') You share all of those qualities in abundance! Perhaps you should try to build on your similarities.
** The EstablishingCharacterMoment for Dr. Bashir in ''Series/StarTrekDeepSpaceNine'' show him as an UpperClassTwit who signed up for what is a disaster relief mission only for his own ego, by telling one of the locals how excited he is about the adventures he will have, while standing inside the remains of a concentration camp.
-->'''Bashir:''' I didn't want some cushy job or a research grant; I wanted ''this'' -- the furthest reaches of the galaxy, one of the most remote outposts available. This is where the adventure is. This is where heroes are made. Right here -- in the wilderness.\\
'''Kira:''' This is my home.
* Reid from ''Series/CriminalMinds'' sometimes falls into this trap, mostly because his social skills aren't great and, therefore, he tends to forget about them when he gets really excited or is concentrating on something. For example, at one point the team is tracking a killer who has kidnapped a young girl that Morgan is very attached to. Rossi worries that a radio announcement might lead the killer to change vehicles. Reid gets about halfway through brightly saying, "Or he might kill the kid!" before seeing the look on Morgan's face and quickly backtracking.
* Castiel from ''Series/{{Supernatural}}'' is particularly prone to the trope. He called Sam an "abomination" in order to explain a point, and complimented Dean by telling him, "you're not the broken shell of a man that I thought you were."
* ''Series/TheOfficeUS'':
** Michael Scott. Even when he's trying to be well-intentioned he doesn't realize how much the things he's saying can be rude or potentially offensive.
** Dwight Schrute casually and without malice insults people who fall short of his standards of efficiency and skill, which is nearly everyone. His coworkers generally blow it off.
* Arthur from ''Series/{{Merlin}}'' is prone to this in earlier seasons [[ShelteredAristocrat towards the poor]]. Best demonstrated in ''The Once and Future Queen'', where he's staying with Gwen, a maidservant from the castle. He offers to cook her dinner and then cheats out on it the first chance he gets. She finds out and confronts him about it. This exchange happens.
-->'''Arthur:''' Look, I can kill a chicken from a thousand paces, just don't ask me to cook it. That's what servants are for.\\
(''Gwen gives him a {{death glare}}'')\\
'''Arthur:''' (''[[OhCrap realizes what he said]]'') I didn't mean.
* On ''Series/{{Gotham}}'' a kidnapper and murderer targets the offspring of wealthy families. Young Bruce Wayne refuses to leave Gotham because he wants to see how the case unfolds, and justifies himself on the basis of being an orphan. "Why would anyone take me? There's no one to take me from." Alfred looks wounded.
* The Twelfth Doctor in ''Series/DoctorWho'' has this as a RunningGag. OnceAnEpisode in Series 8, he attempts to compliment Clara's appearance in a way that would reveal he has absolutely no understanding of human beauty or feelings - like asking why she's wearing high heels because there's no reason for her to be taller, or assuming she's taken off her makeup while she's obviously still wearing loads before kindly advising her that it's what's on the inside that counts.
* Most characters of ''Series/{{Firefly}}'' fall into this at one time or another, but Simon is the biggest offender whenever he talks to Kaylee.
* Series/DowntonAbbey: The Duchess of Yeovil visits the house in season 4 and happily strikes up a conversation with Tom. She offers her condolences for [[spoiler:Sybil's death]], and while she's trying to sympathize (having lost her husband), it just opens up the still healing wounds [[spoiler:of her passing]]. She also talks to him at length about the Anglo-Irish Aristocrats she calls friends expecting him (Irish himself) to follow along. Tom has absolutely no idea what she's talking about, and it makes him realize how he doesn't fit in high society. It feeds into his arc of being lost and confused about his place in the world. When talking to Lord Grantham later, Tom clarifies that the Duchess was very polite and she tried her best to include him, he just feels that he isn't right for such inclusion.

[[folder: Music]]
* [Music/{{Voltaire}}] has the song "Dunce" from his album "Almost Human".

[[folder:Video Games]]
* Red from ''VideoGame/{{Solatorobo}}''. His sister Chocolat is constantly chiding him for not understanding girls' feelings, and Elh calls him "an idiot with a bad mouth" when he continues to [[OpenMouthInsertFoot stick his foot in there]].
* Minsc in ''VideoGame/BaldursGate'' being a brain-damaged warrior with the mind of a child, has a few banters that paint him in this light. Everyone realises his true intentions, and nobody ever gets permanently insulted. Boo is also quick to correct him when he puts his foot in his mouth.
* Girl!Morgan in ''VideoGame/FireEmblemAwakening'' is a kind-hearted GenkiGirl, but she can be sometimes rather pushy with her love interests. May be somewhat of a JustifiedTrope as she not only [[spoiler: has heavy LaserGuidedAmnesia]] but seems to be the youngest of her group of friends and thus is more sheltered than them.
* ''VideoGame/TheKingOfFighters'':
** Athena Asamiya shows some traces of this, specially in KOF XIII. She launches in a RantInducingSlight when she sees Kula fighting despite her ''willingly'' being there, inadvertently embarrasses her friend Kyo via asking him [[BerserkButton if he did graduate from high school]]...
** Kyo's girlfriend, Yuki was like this in the manga. After learning that he and Athena fought in the previous tournament, she becomes angry at Kyo for "beating on girls". Being a martial artist herself, Athena feels insulted.
* In ''VideoGame/{{Persona 4}}'', the first time Youske, Chie, and Yukiko meet Nanako he challenges Chie to a cook-off, offering to have Nanako judge and saying that one of them would probably "make something that ranks up there with your mom's cooking." Nanako points out that her mother died in an accident, and forgives him for saying that when he quickly apologizes.
* ''VideoGame/DragonAgeInquisition'' has Cole, a spirit of compassion who took on human form. He's able to read others' minds to find out what's hurting them so he can try to help...but he tends to say what he's reading from them out loud and doesn't understand why certain things should or should not be said, be they personal traumas or [[DirtyMindReading the party's relationships and sexual activities.]] He doesn't understand what's wrong it it, since spirits in the Fade do it all the time. [[spoiler: Helping him become more human can help him start to grow out of this.]]
* Maxim in ''VideoGame/LufiaIIRiseOfTheSinistrals''/''VideoGame/LufiaCurseOfTheSinistrals'' constantly infuriates Tia with his inability to recognize her feelings and concern towards him. The remake even names one of Maxim's Titles "Insensitive".

[[folder:Visual Novels]]
* ''VisualNovel/KatawaShoujo'':
** Shizune Hakamichi can come across as being very blunt to point where she comes across as being flat out bossy. This is in part the result of her being deaf and because of this communicating with others directly is difficult for her along with the fact that she cannot perceive vocal cues of emotion and intent in other people. It does not help that her interpreter Misha seems to have her own troubles reading social cues in other people, leading to more than a few "blind leading the blind situations" [[spoiler:including the panic attack incident in Hanako's route]].
** Hisao himself falls into this at times, especially early on when he's not sure how to talk to people with disabilities. This can be a problem in [[spoiler:Hanako and Emi]]'s routes; in the former, [[spoiler:he can deeply upset her if he pities her too much]], and in the latter, [[spoiler:he can anger Emi if he is too aggressive in trying to protect her]].
* Sakuya Shirogane Le Bel from ''VisualNovel/HatofulBoyfriend''. Classist (to Ryouta and the player character), racist (to Yuuya, Anghel, and the player character), ableist (to Oko San), and a royal UpperClassTwit, and it takes him most of the game, ''if the player's on his route'', to even acknowledge that these are bad things. However he also has a FreudianExcuse: his father raised him to believe himself above everybirdy else, and Sakuya cannot comprehend that his father could be wrong. [[spoiler: In the Bad Boys Love route, finding out that not only was his father wrong but ''[[SwitchedAtBirth not even his father]]'' gives Sakuya a full-blown HeroicBSOD]]. In Anghel's route, Sakuya says quite a few racist things about Anghel in the presence of the player character, who echoes them later.

[[folder:Web Animation]]
* In ''WebAnimation/{{RWBY}}'', Jaune -- being unaware of Pyrrha's feelings for him -- sees nothing wrong with pouring out his romantic woes to her.
* In ''WebAnimation/XRayAndVav'', Mogar, a man who has seemingly lived his entire life away from most civilization, [[spoiler:is coerced into aiding The Mad King in escaping and crushing our heroes.]] Though, when Mogar agrees, he refers to them as "those two colored people". While he ''obviously'' is talking about their brightly colored spandex, [[spoiler:The Mad King]] makes a point to let ''him'' do the talking instead of Mogar just for that reason.

[[folder:Web Comics]]
* Katherine of ''Webcomic/WapsiSquare'' is remarkably observant, but lacks any social skills, so it makes sense that she would fall into this trope at times.
* Marty of ''Webcomic/DubiousCompany''. He has no idea why [[DudeLooksLikeALady Elly]] isn't into him or why [[BelligerentSexualTension Sue]] wants to shove her boot up his rectal cavity. He is able to [[SelectiveObliviousness recognize]] when he pisses off his [[KnightTemplarBigBrother brother]], though.
-->'''[[TheStarscream Izor]]:''' Something needs to be done about [[ModernMajorGeneral Walter]].\\
'''[[ChivalrousPervert Marty]]:''' Yeah. No fair keeping all the cute ones up on the bridge. All we get is [[DeathGlare Sue]] [[ImStandingRightHere here]].
* Jake of ''Webcomic/{{Homestuck}}''. Most likely due to his upbringing as an orphaned, isolated inhabitant of a deserted jungle island, Jake has a tendency to be oblivious to the feelings of others, mostly Jane's. It's also implied that in his previous incarnation as Grandpa Harley, he was similar and ran away from home and from Nanna without apparently considering how it made her feel.
* ''Webcomic/GirlsWithSlingshots'':
** Hazel is not good with lesbians, babies (and people who have them), animals, or her boyfriend. (The last gets her dumped.)
--->'''Jamie:''' ''Why'' are we friends, again?
** Candy's reactions to being called out on her misandry seem to point to her being this way, too... though attempted rape is kind of pushing the definition of "innocent".
* ''Webcomic/StandStillStaySilent'': Lalli and Emil come at this trope from separate directions. Lalli is LiteralMinded, NotGoodWithPeople, prefers to [[IWorkAlone work alone]] and is suspected to have some form of Autism Spectrum Disorder, all leading to someone with little use for social niceties. Emil, on the other hand, is a SpoiledSweet JerkWithAHeartOfGold and a good person at heart... as long as he can remember that [[ItsAllAboutMe there are other people in the world than him.]]

[[folder:Western Animation]]
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Pinkie Pie often falls into this trope.
*** In "The Super Speedy Cider Squeezy 6000", she can't stop gushing about how great the cider at Sweet Apple Acres is, despite Rainbow Dash (who didn't get any cider) growing increasingly irritated. What makes it even worse is that Pinkie Pie had also a) gave the suggestion to other ponies to camp out in front of the cider stand, b) was in front of said line and c) put up a pile of coins and walks off with at least ''ten'' mugs of the frothy stuff without realizing that others wouldn't get sips. Thankfully she gives one of her mugs to Rainbow Dash at the end.
*** The episode "A Friend in Deed" is basically twenty minutes of Pinkie Pie annoying Cranky Doodle Donkey while trying to cheer him up.
*** And she unintentionally helped cause the termination of Nightmare Night in "Luna Eclipsed" due to managing to alienate Princess Luna. She genuinely thought it was just part of the fun.
*** She takes this to the extreme during "Filli Vanilli", constantly setting off Fluttershy's stage fright and upsetting her.[[note]]This particular instance created a strong backlash from the fanbase.[[/note]]
** [[NoSocialSkills Twilight Sparkle]] is pretty prone to this herself.
*** In "Baby Cakes", she innocently tells Pinkie that she knew that Pinkie probably couldn't handle the responsibility of caring for baby twins. She doesn't seem to notice that Pinkie is offended by this, even as she is pushed out the door.
*** In "The Last Roundup", Twilight slams the door in the face of a mailpony after getting a letter from Applejack. ''On his birthday''. Granted, she was worried about her friend, but you can't help but feel sorry for him. (Pinkie Pie does give him a slice of cake, though.)
*** When researching the Mare in the Moon, she dumps a pile of books on Spike's head looking for the right one, and doesn't even notice.
*** In "Spike At Your Service" she once again is so buried in her work fails to notice Spike as he tearfully explains [[IOweYouMyLife he is honor-bound to serve Applejack]] and must leave her. She is visibly guilt-ridden when Applejack later coaxes her out of her studies and explains what happened.
** The episode "Dragon Quest" has Rarity telling Spike that he's better than the other dragons, because he has something special that they don't. Spike gleefully asks what it is, and then Rarity says he has "The cutest [[BabyTalk widdle]] chubby cheeks," unintentionally humiliating him in the process:
--->'''Rarity:''' Oh, isn't he adorable when he waddles off in anger?\\
'''Spike:''' Waddle!? '''GAAHHH!'''
** Spike himself has bouts of this due to his sometimes obnoxious sense of humor and inadvertent bluntness. In "Hurricane Fluttershy", he constantly aggravates Fluttershy's low confidence concerning her poor flying skills, but just doesn't get why Twilight keeps giving him nasty glares.
** Fluttershy also falls into this category several times, such as when she makes Rainbow Dash's stage fright even worse in "Sonic Rainboom", describing how ''everyone in Cloudsdale, including the Wonderbolts and Princess Celestia'' would be watching her and see any mistakes she made.
** The Cutie Mark Crusaders, when inviting Babs Seed into their club, make her painfully aware of her lack of a cutie mark, something she came there to forget about in the first place.
* Parodied in a ''WesternAnimation/FamilyGuy'' skit about high school kids (and no, [[MakesJustAsMuchSenseInContext this isn't taken out of context]]):
-->'''Girl:''' Hey Tyler, you going to algebra?\\
'''Tyler:''' Yeah, I'll see you there.\\
''[The girl instantly breaks down bawling, then [[DrivenToSuicide leaps out a two-story window]]]''\\
'''Girl's friend:''' You're ''awful!''\\
'''Narrator:''' The preceding joke is brought to you by: Men.\\
'''InvisibleBackupBand:''' [[CrossesTheLineTwice Men! We don't know what we did!]]
* ''WesternAnimation/{{Futurama}}'': Done repeatedly in "War is the H-Word", where Leela is pretending to be a macho guy, and Bender unknowingly "compliments" her on the macho stereotypes least suited to a woman:
-->'''Bender:''' You're my kind of soldier, Lemon. A foul-mouthed, barrel-chested, beer-bellied pile of ugly muscle.... But sweet girls aren't for you, eh? You hard-fighting, hard-farting, ugly, ugly son of a--\\
'''Leela:''' Stop! Stop flattering me!
* Cyborg in ''WesternAnimation/TeenTitans'' in the episode "Troq", when he calls Starfire by the title word. Throughout the episode, [[FantasticRacism the racist Val-Yor]] has been calling her this, and Starfire told Cyborg it meant "nothing" (without explaining that it meant "nothing" as in "worthless"), meaning he didn't realize how hurtful it was. Becomes a case of BullyingADragon when you remember this is a race of super-strong beings who have EyeBeams and energy-hurling abilities.
* ''WesternAnimation/TheLegendOfKorra'':
** Korra was trained for most of her life in a compound where she could be taught the four elements in safety, but as a result when she enters the world as a teenage girl she has NoSocialSkills and winds up greatly exacerbating a LoveTriangle she winds up in because she has no firsthand experience with romance. At one point she plants a ForcefulKiss on her crush after he admits to liking her and honestly doesn't seem to grasp that it's a problem (at first), since he's already in a relationship with someone else.
** Tenzin's declaration that the Air Nomads will help restore balance until Korra recovers from her injuries at the end of Season Three; while it might not seem that bad, earlier Korra had seen hallucinations of previous villains telling her she was no longer needed, and here's her mentor implying the same thing. [[BreakTheCutie She doesn't]] [[TearJerker take it well]]. During Season Four, she calls him out when he acts this way towards her which causes him to backpedal in what he tries to tell her.
** Opal Beifong has moments of this when she tries to strike up a teen romance with Bolin, since Opal was raised in the wealthy Metal Clan family and thus has little to no idea of just how hard life can be for someone like Bolin who comes from a lower to middle class background. She's basically the SpoiledSweet rich girl to his blue collar working man.
* In ''WesternAnimation/SpongebobSquarepants'', we have the title character himself. All though [=SpongeBob=] means well, he unintentionally ruins other peoples' lives. Just ask [[ButtMonkey Squidward]] or his boating school teacher Mrs. Puff.
* ''WesternAnimation/MoralOrel'': Orel Puppington falls under this at times. He's actually a kid with good intentions, but as he's young, naive and often misinterprets advice from other adults, he usually ends up causing more bad than good for people.
* Dee Dee of ''WesternAnimation/DextersLaboratory'' is this at her worst. For the most part, she's just trying to have fun, but she constantly ends up wrecking Dexter's lab and causing him no small amount of grief in doing so.
* ''WesternAnimation/KingOfTheHill'': Dale doesn't realize his son Joseph's true parentage, leading to this exchange with John Redcorn (Joseph's biological father):
-->'''John Redcorn:''' Joseph hates me...\\
'''Dale:''' Why would Joseph hate you? He barely knows you.
* In ''WesternAnimation/MikeTysonMysteries'', "Ty-Stunned", everyone, minus Yung, unintentionally acts insensitive to Miss Ensler when they keep bringing up her husband's mutilated body. Mike Tyson is a big offender when he's having a business meeting with his agent during the mystery.
-->'''Mike''': Hey, Miss Ensler, I know you're still grieving, but I want your honest opinion, okay. Do you think I should have a line of neckties?\\
'''Marquess''': Michael!\\
'''Ensler''': Richard loved ties. [[OffWithHisHead They cut off his head!]]\\
''(Miss Ensler starts sobbing)''\\
'''Mike''': Okay, let's do it! Mike Tyson is in the tie business.

[[folder:Real Life]]
* People with poor social skills -- children and shy people who haven't had much chance to interact socially especially -- are also prone to this. It's a recognized symptom of Asperger's Syndrome, since sufferers are bad at picking up non-verbal cues that would alert them to other people's feelings.
* Can also happen when you go to another culture. Even if you speak the language, the complexities of social interaction can take a while to learn, and it'll often involve a lot of unintentional insults to the people whose country you're in before you figure out what you should and should not do.
* This can also happen in avowedly progressive circles. Black feminists frequently complain about the feminist movement focusing exclusively on issues that affect white, middle-class women and ignoring their own privilege. A book by well-known feminist blogger Amanda Marcotte contained racist illustrations from an old comic. Although Marcotte apologized and the book was reissued, the black feminist blogosphere has never forgiven her.
* A French blogger launched a website where women could post the most sexist lines they heard all day. One newspaper article accompanied this with a cartoon where two women said as much to an impressed man, who answered that, "It's nice to finally see women who've got a pair."
