History Main / WillNotTellALie

A character who isn't trying to get around his principle of honesty is a kind of [[ForGreatJustice deontologist]], but if they take it a bit too far they might also be a PrinciplesZealot.

* In ''Manga/DrStone'', Senku claims "Science doesn't lie", and neither does he when it comes to science, even in situations where doing so would benefit him. Early on, when Tsukasa holds Yuzuriha hostage and demands to know the formula for the "miracle water", Senku complies rather than giving him a false formula just to save his friend. When they're trying to sway Nikki to their side, she asks if they can bring back Lillian Weinberg's music; Gen encourages him to lie and say yes, but Senku admits that all music storage media from their time have long since crumbled into dust.
* Greed of ''Manga/FullmetalAlchemist'' considers it a matter of principle never to tell a lie. [[spoiler:In the end, he finds [[HeroicSacrifice one worth telling]]]].

* Satsuki, of ''Manga/UsotsukiSatsukiWaShiGaMieru'', ironically for someone who has earned a reputation for being a CompulsiveLiar, is this in reality. When her friends challenge her to lie about even relatively minor and harmless things, she still refuses to do so--and when she at one point lies about jumping off a building as part of a scheme to save someone's life, she ''actually goes through with it'' solely because doing otherwise would make her a liar. As it turns out, she has some major-league trauma relating to the one time in her past that she ''did'' tell a lie.

* ''ComicBook/{{Batwoman}}'': Katherine "Kate" Kane was a Cadet Captain at West Point, highly regarded by both her fellow students and also her instructors and serving officers, when rumors begin to circulate that she is gay. The commanding officer of the facility calls her into his office, explains the situation, and gives her a choice: She can undergo a formal investigation, be revealed a homosexual and be kicked out of the academy, or she can say right now that the entire thing was a misunderstanding, a rumor, or even just an isolated incident and have the entire affair swept under the rug with no further questions. If she says the right thing she will still lose her status as Cadet Captain and will not graduate at the head of her class, but she ''will'' graduate, and will then go on to be the officer that she wants to be.

* In ''ComicBook/LokiAgentOfAsgard'', [[ConsummateLiar Loki]] wonders if the true reason they CannotTellALie after the Inversion event is because part of them just doesn't ''want'' to lie anymore.

** In ''ComicBook/Superman1939 #176'', Superman and ComicBook/{{Supergirl}} celebrate a Kryptonian holyday called the Day of Truth in which they ''have'' to speak nothing but the truth, no matter the cost. It is not an easy task because they are ''incredibly'' and rudely blunt when they are being honest. Also, several crooks ask Superman about his secret identity and his Fortress' location.
** In week 34 of the ''ComicBook/FiftyTwo'' series, some of Luthor's thugs kidnap a depowered Clark, drug him with truth serum, and ask him a question about Superman's secret identity. Specifically, they ask "[[spoiler:Why is the Man of Steel masquerading as Supernova]]"? He cracks up.
* Franchise/WonderWoman ''can'' lie when she's not touching her Lasso of Truth, she just doesn't. In ''ComicBook/WonderWoman1987'' when time travel circumstances force her to try preventing her mother from learning who she is Hippolyta is shocked and amused that her daughter "lied" to her, but even that "lie" was more a half-truth and was apparently the first time Diana lied in her life despite being at least thirty by that point.

* In ''Literature/TheSilmarillion'' fanfic, ''Fanfic/ABoyAGirlAndADogTheLeithianScript'', Finrod tells Beren that he can keep quiet about things Beren would want to know of, but he would never lie to his friend.

* Invoked in the ''WesternAnimation/KimPossible'' fic "[[https://www.fanfiction.net/s/3038776/1/Eric Eric]]", where Kim initially chooses to go to the prom with Eric after he turns out to be real (Drakken replaced him with a synthodrone as part of his plan to demoralise Kim). When Kim nevertheless chooses to seek out Ron and ask him if he was genuinely going to say he had deeper feelings for her, Ron initially considers lying as it might save their friendship and he reasons he never had a serious chance with Kim anyway, but ultimately concludes that he could never deceive Kim like that.

* Ben Gates of ''Film/NationalTreasure'' is uncompromisingly honest about his work, only using subterfuge if he sees no other means to his goal, and even then he tends to lay all his cards out on the table.

* Father Lonergan in ''Film/TheQuietMan'' won't tell a lie because he believes it's morally wrong. At one point, in order to trick someone into doing the right thing, he made the statement "I can´t say it´s true, and I won´t say it´s not. But there's been talk." Of course, the reason he can't say it's true because it's not true, and the rest of the statement is just vague enough to imply it's true without ever actually lying.
* At the conclusion of ''Film/SmokeyAndTheBandit,'' the Bandit and Snowman make it to Atlanta with truckload of Coors beer followed by Sheriff Justice. Via CB radio, the Bandit tells Justice where he is when he's really detailing Big and Little Enos. But then he has a change of heart:
-->'''Bandit:''' I can't lie to you, sheriff. You're too good a man. Look over your left shoulder. (''Turns slowly; sees Bandit, Snowman, Fred and Frog in a convertible'')
* ''Film/SupermanTheMovie'': [=KAl-El=] expressly states that he never lies.

* In one joke, a priest helped a woman to smuggle a hair dryer by hiding it within his pants. When asked if he had anything to declare, he stated he had a wonderful instrument meant to be used by women that has never been used before.
* The German punchline equivalent would be the priest saying about his contraband "ja, aber ich habe sie unter den Armen verteilt". [[note]]Playing with the grammatically slightly inexact - "den" should be "die" - double meaning "yes, but I carry it divided under my arms" and "yes, but I donated it to the poor".[[/note]]

* The Kencyr peoples in P.C. Hodgell's ''Literature/ChroniclesOfTheKencyrath'' series have a rigid honor code in which lying is one of the most serious offenses, for which a honorable death (suicide, or death in battle) is the only way to redeem oneself. This nature is known to others, as when Jame is called as a witness in a scene in ''God Stalk'':

* The Minds in [[Creator/IainBanks Iain M. Banks]]' [[Literature/TheCulture Culture]] series do not lie.
** "They dissemble, evade, prevaricate, confound, confuse, distract, obscure, subtly misrepresent and willfully misunderstand with what often appears to be a positively gleeful relish and are generally perfectly capable of contriving to give one an utterly unambiguous impression of their future course of action while in fact intending to do exactly the opposite, but they never lie. Perish the thought."

* ''Literature/{{Discworld}}''

* In Creator/AlexanderKey's ''Literature/TheForgottenDoor'', Jon is puzzled by the concept of a white lie because his people always tell the exact truth, no matter what the circumstances.

* In Creator/CSLewis's ''Literature/TheHorseAndHisBoy'', Shasta suggests to Corin various ways he could cover up the facts, but realizes it's impossible and says he will have to tell the truth. Corin scornfully says that of course he would have told the truth.
* In ''Literature/IWasASixthGradeAlien,'' also by Creator/BruceCoville, Pleskit, the son of the first alien ambassador to Earth, is told that humans in general hate lying. As a result, he uses BrutalHonesty whenever he interacts with him -- which naturally results in some problems. Only when he befriends Tim does he learn that humans lie ''all the time'', and that the false information was planted by a saboteur wanting to engineer diplomatic incidents.
* In Creator/EdgarRiceBurroughs's ''The Gods of Mars'' from ''Literature/JohnCarterOfMars'', Thuvan Dihn supports John Carter's claims because
-->"It is not a lie. This much have I learned of the Prince of Helium--he does not lie."

* In Creator/RobertEHoward's ''The Shadow Kingdom'' Literature/{{Kull}} insults a Pict by claiming Picts never tell the truth, even though they follow this trope.
* The title character of Creator/JamesFenimoreCooper's ''The Deerslayer'' from ''Literature/TheLeatherstockingTales''.
--> Truth was the Deerslayer's polar star. He ever kept it in view, and it was nearly impossible for him to avoid uttering it, even when prudence demanded silence.

* [[EvilOverlord The Lord Ruler]] from ''Literature/MistbornTheOriginalTrilogy'' has a reputation for never lying - after all, he's an omnipotent GodEmperor, so why would he ''need' to lie to get what he wants? [[spoiler: While he never tells an explicit lie on-page - even his rant about being TheChosenOne and the Avatar of God is true from his perspective - he is willing to mislead his followers about his true origins, so they don't uncover the secret of his power]].

* ''Literature/{{Ravirn}}'': Eris, as VillainsNeverLie, usually:
--> Why bother when the truth is usually so much more devastating?
* ''Literature/RodAllbrightAlienAdventures'': Rod will not lie, even when aliens crash land in his room and eat his homework, a tale that he knows no one will believe. [[spoiler: He lies right to the face of a police officer at the end of the story to protect his alien friends.]]
* Creator/DavidWeber's ''Literature/{{Safehold}}'':

* Creator/SpiderRobinson's story "Satan's Children" describes the societal effects of [[TruthSerum a drug that makes people tell the truth]]. Even after the drug wears off, users continue to tell the truth because they find that honesty [[GoodFeelsGood just feels better]].

*** Seleneans and Zaldans. The Seleneans are only a partial example - their truthful nature is more a result of their usual form of communication rather than for moral reasons. Zaldans, on the other hand, are fanatical in their Will Not Tell A Lie morality. This causes problems in one novel, ''Literature/ASingularDestiny''. Evidence suggests that planet Zalda is refusing refugees; this isn’t true, but the faked records are convincing enough. The situation is made considerably worse in that their representative is completely outraged at the very idea of being WronglyAccused - of being ''lied'' at and made to look like a liar himself - and storms off rather than defending himself.

* In Albert Camus' existential novel ''Literature/TheStranger'', the main character Meursault never ever tells a lie. He is not a textbook example, though, because this does not seem do be a conscious decision of his - it just never occurs to him that lying might help his situation.

* In Creator/PoulAnderson's "Brave To Be A King" from ''Literature/TimePatrol'', Manse listens to a story that is clearly MosesInTheBulrushes and so a hero legend -- but from a Persian, and he knows the Persians are fanatical about this.
* In Creator/WenSpencer's ''{{Literature/Tinker}}'' series, the elves are fanatical about this. Tinker has to be very careful about shading the truth and lying by implication around them, and Tommy at one point faces a serious dilemma because the elves will take the printed team list and his having taken bets as unbreakable.

** The Minbari like to claim this, but the rule has a wide range of exceptions, the biggest one being to preserve another's honor (only another's, mind you, not one's own). Lennier taking the blame for Londo's cheating at poker in the first season actually becomes something of a ChekhovsGun in a second season episode where Sheridan is accused of murdering a Minbari.
** In one episode, [[TheCaptain Sheridan]] is tortured by [[TortureTechnician a professional]]. The interrogator says that he will not ever lie to Sheridan, and he continues to assert that throughout all of their sessions. However, [[SubvertedTrope that statement is itself a lie]], as he lies constantly (and contradictorily) throughout the episode. He attempts to justify this by claiming that [[MetaphoricallyTrue there is no such thing as an objective truth, and that because he can]] ''[[MetaphoricallyTrue make]]'' [[MetaphoricallyTrue whatever he says true for John specifically then it is true regardless of the facts]].
* One of the Corpses of the Week on ''Series/{{Bones}}'' was in a 'Radical Honesty Group' and prompted the whole Jeffersionian to adopt this trope for the episode, HilarityEnsues.
* ''Series/{{Forever|2014}}'': Not an absolute for Henry, but he generally tries to tell the truth as much as he can, often using ExactWords and MetaphoricallyTrue to avoid telling outright lies whenever he can. An excellent example is Henry telling Jo what "Abe's mother" meant to him, keeping in mind that Jo has no idea Abe's mother is also Henry's wife Abigail, the love of Henry's life, and they were together for forty years and raised Abraham together from a baby.

--->'''Tyrion''': I'm glad you chose to bend the knee. I would have advised it. But would it kill you to learn to lie, just a little bit?\\
'''Jon''': I'm not going to lie, nor am I going to keep secrets. Tell me my father died because of this way of thinking, but when enough people make enough lies and secrets, words lose their meaning, and then there's no meaning, only bigger and better lies.
*** On the other hand, Jon did tell Stannis something that could either be interpreted as a lie or at least a blatant exaggeration earlier on. Stannis had just invaded the wildling camp, where Jon was meeting to arrange a cease-fire with Mance Rayder. They come out, and are captured by Stannis' men. Stannis then asks Jon what Eddard Stark would do. Jon praises Mance as an honorable man who treated him well as a prisoner (Jon and his companion were force-marched and verbally abused, Jon had to kill his friend to convince the wildlings he was a defector): Mance raises an eyebrow subtly, but wisely plays along. Then Jon claims that Eddard Stark would have shown mercy, when "merciful" isn't among the adjectives most would use to describe the late Lord of Winterfell. The actual truth is that Jon simply refuses to lie to save his own skin. [[spoiler: As evidenced by how he originally died.]] However, he will gladly lie-and do it well-if it's to save someone else. Which makes what Jon told Tyrion at least not quite the truth.

* ''Series/GoodOmens2019'': Played with.
** [[OurDemonsAreDifferent Crowley]] is a demon, so [[ConsummateLiar lying is like his second nature]], except he is not able to ever tell a lie to his [[BestFriend best friend]] ([[spoiler:and [[OneTrueLove one true love]]]]) [[OurAngelsAreDifferent Aziraphale]]:
-->'''Crowley:''' The Hellhoud has found its master.
-->'''Aziraphale:''' Are you sure?
-->'''Crowley:''' I felt it... ''(offended)'' Would I lie to you?!
-->'''Aziraphale:''' Obviously! [[HolierThanThou You're a demon, that's what you do]]!

* One PatientOfTheWeek on ''Series/HouseMD'' is a woman who will not lie to her daughter. House is astounded, since this challenges his "[[CatchPhrase everybody lies]]" philosophy.
* Loker on ''Series/LieToMe'' abides by "radical honesty," which means he not only always tells the truth, but he also blurts out whatever he's thinking, no matter how inappropriate that may be.
* ''Series/Lucifer2016'': Despite his moniker as "The Prince of Lies", Lucifer is always completely honest about being the Devil, but [[CassandraTruth nobody ever believes him]]. If anything, he's actually ''averse'' to lying and often drifts into oversharing. The closest he gets to being dishonest is by omitting details from otherwise true stories, e.g. when he tells Chloe that a shipping container that was stolen from him contains Russian nesting dolls (which it does), but leaves out that it also contains his severed angelic wings. In a particularly heartbreaking moment, Trixie demands that Lucifer be the one to tell her that [[spoiler:her father, Dan, really is dead]] because she knows he won't lie to protect her feelings. Lucifer's unfailing honesty is so well known to those around him that it becomes one of the ways to tell him apart from his twin brother [[ArchangelMichael Michael]]. When the latter tries to pull off a TwinSwitch he has to come up with an elaborate excuse about why "Lucifer" is suddenly willing to lie.

* On ''Series/NecessaryRoughness'' Nico informs Dani that he does not lie. While he is never shown on the show to lie, he uses a lot of euphemisms and does not really explain things fully when asked.
* ''Series/{{Oz}}''. Unit Manager Tim [=McManus=] is faced with telling what he knows about the death of prisoner Scott Ross or lying. Kareem Said asks him (under oath) if prison officer Diane Wittlesey shot Ross "with the intention of ending his life." So [=McManus=] says "No" (though he may have been answering very literally, as in: "Diane shot Ross with the intent to save my life"). Nevertheless the situation bothers [=McManus=] enough to have Diane transferred to another part of the prison, away from him.
-->'''Diane''': "Look, can we just cut the shit? You are going to say you have a conscience, right? A moral code... seepage in your cerebral cortex and I am going to say, 'lie'. If you love me, if you ''ever'' loved me, then lie."

* Maura Isles from ''Series/RizzoliAndIsles''. She will be evasive, however. When the sensitivity trainer asks her where Detective Rizzoli is, Maura replies that she is sure Rizzoli is "in the building", but that she "can't see her at the moment". Both of these statements are literally true as Rizzoli is [[spoiler: hiding behind Maura's door at the time]].

* From ''Franchise/StarTrek'':

** Also in ''The Next Generation'', the android Data seems highly opposed to lying to the extent that it was (initially) practically a part of his programming (well, that, plus the fact that he's really ''bad'' at it). So much so that a good way to get information out of him was to construct your question into the form of an order, as Picard did during the episode "'Clues'". If you were at least one rank higher than him, then there was absolutely no way he could refuse to tell you. This usually worked (unless another previously given order overrode the new one). It also meant that he was usually trusted without question when reporting on a particular situation -- which means the times when he ''did'' lie, he usually got away with it. One of his more notable examples is attempting to kill a murderous kidnapper threatening future harm to others if Data didn't accede to his demands. Data reluctantly accepts that the only way to prevent the man from carrying out his threat is indeed to kill him first and fires at him, but it happens to be at the exact moment that he himself is transported to safety. When asked about the discharged weapon (disarmed mid-transport) he provides a half-truth that "perhaps something happened during transport". [[ExactWords It's possible]] that something ''else'' happened during the transport, but it's an evasion to avoid explaining that he had deliberately decided to take the life of an unarmed man who posed no (immediate) threat.
** Vulcans are often perceived as this by others, but in fact they see no problems with lying if it's the logical thing to do. Their culture's ethical standards hold one should not lie '''unless it is absolutely necessary''', but if logic dictates that it's necessary, then they will lie and can generally do so quite convincingly. Spock was known to "exaggerate", and even tell outright falsehoods, on numerous occasions. Aptly displayed in the first reboot film with the two Spocks. After discussing why Old Spock sent Kirk to do the work instead of going to explain everything personally:
---> '''Young Spock:''' How did you persuade him to keep your secret?
---> '''Old Spock:''' He inferred that universe-ending paradoxes would ensue should he break his promise...
---> '''Young Spock:''' You lied?
---> '''Old Spock:''' Ah... I-- I implied.

---> '''Saavik:''' You lied!
---> '''Spock:''' I exaggerated.
*** Discussed again here (bear in mind that Tuvok has been a spy and infiltrator during his Starfleet career, which obviously required him to lie):
---> '''Seven:''' Commander, am I correct in assuming that Vulcans are incapable of lying?
---> '''Tuvok:''' We are capable of telling lies. However, I have never found it prudent or necessary to do so.
---> '''Seven:''' You have never lied?
---> '''Tuvok:''' Only under orders from a superior officer.

** In ''Series/StarTrekVoyager'', Janeway claims this about Q. The ''WebSite/SFDebris'' review responded with a clip show of times Q has blatantly lied, and that he's known as the God of Lies on one planet. Clearly, Janeway doesn't know Q very well.

* Podcast/DiceFunk: Jayne hates telling lies, even if it is a necessity, and will then disclose the truth when it is safe to do so.

* In ''TabletopGame/GeniusTheTransgression'' the [[MadScientist Peerage]] is steadfastly against lying, though the attitude is fading. This is because the oldest and most respected organization of mad scientists in the world traces it's origins back to a Zoroastrian philosophy cult.
* In ''TabletopGame/{{GURPS}}'' the "self imposed mental disadvantage" Truthfulness is for characters that hate lying and are obvious when they try.

* This is Terumi's schtick in ''VideoGame/BlazBlue''. Lying is, in fact, even a BerserkButton for him... Besides, what better way to MindRape somebody than HannibalLecture-ing them with {{Awful Truth}}s and BrutalHonesty; like revealing to them that their desired rightful place in the world was stolen away by their best friend, who only exists because of causality-interference effects screwing with the [[StableTimeLoop time loops]], or that they're really just a failed version of an EldritchAbomination, which ''in turn'' is a failed version of a PersonOfMassDestruction?

* VillainProtagonist Kain from the ''VideoGame/LegacyOfKain'' series is a horrible person, but never directly lies. In a plot that includes half a dozen time travellers trying to trick each other into doing things that are against their own interests, this is a welcome though unexpected break. He still does his fair share of manipulating, but he never hides that he is only telling half the facts and hopes that sharing them will benefit his own goals. There is one point where he does lie (promising mercy to someone he fully intends to kill,) but he is immediately called out on it, and calmly acknowledges that his victim is correct.
** Kain is an interesting use of this trope in that it seems highly unlikely that his honesty comes from any moral qualms; he is as ruthless and selfish as they come. It seems more likely that he is simply too proud to lie, as shown when he calmly admits to personally killing [[spoiler: Umah]], even though it could have been against his interests to do so, and the person to whom he admitted it actually thought Kain had simply been unable to save her until Kain chose to correct him. Another possible reason is that the usual target of his manipulation (his "son" [[DarkMessiah Raziel]],) has the sort of personality that causes him to seek the truth of his own accord, so simply hinting at the time-spanning GambitPileup into which he is blundering is usually enough to get him on the path Kain wants.

** Turians are described as such in the codex, as a matter of personal honor. A turian who commits a crime will do everything he can to avoid getting caught, but if flat-out asked, will freely admit it. Turian culture has a thing about personal responsibility. It is mentioned that a turian using illegal recreational drugs while off-duty in a way that wouldn't halter their ability to do their job and duty, no turian would blink an eye. This also causes turian arc villains in the series being seriously prone to start giving {{MotiveRant}}s. There is also some FridgeBrilliance / AllThereInTheManual: adult turians are given TribalFacePaint signifying their colony of origin from before their Unification War, and people that dishonor their ancestors are refused their Face Paint. It is mentioned that the slur ''bare-faced'' is used amongst turians to describe untrustworthy individuals (and politicians). The two bare-faced turians we meet in the games? The BigBad Saren from ''VideoGame/MassEffect1'' and the ArcVillain Warden Kuril in ''VideoGame/MassEffect2''.

--> L-Lie? How dare you accuse me of such an impure act? I despise lying! I wouldn't lie to you or anyone!

* The Ur-Quan Kzer-Za in ''VideoGame/StarControl 2''. They claim that lying is for the weak, and the Ur-Quan are NOT weak.

-->'''Antimony''': Coyote, can you tell me: what ''is'' Gunnerkrigg Court?
-->'''Coyote''': Why... it is Man's endeavor to become God! How's ''that'' [[LampshadeHanging for an enigmatic answer]]?
-->[...]
-->'''Antimony''': So, was anything that [the wisp] said true?
-->'''Coyote''': I'm sure some of it was.

-->'''Scratch''': Lies of omission do not exist. The concept is a very human one.\\
Your demands are based on a feeling of entitlement to the facts, which is very childish. You can never know all of the facts. [[TheOmniscient Only I can.]]\\
If I do not volunteer information you deem critical to your fate, it possibly means that I am a scoundrel, but it does not mean that I am a liar. And it certainly means [[YouDidntAsk you did not ask the right questions.]]

* Durkon of ''Webcomic/TheOrderOfTheStick'' is a Lawful Good dwarven cleric, so it makes sense that he's reticent about lying, especially when dealing with other Lawful Good types, as seen in [[http://www.giantitp.com/comics/oots0264.html this]] strip. [[MetaphoricallyTrue Technically, he doesn't.]]
-->'''Durkon''': I can swear on Thor's beard that the ''five'' of us never left our cells.
-->'''Miko''': Then what of the cell doors? How did they become unlocked?
-->'''Durkon''': I cannae lie to ye. 'Twas a mechanical defect.
-->'''Roy''' [aside]: "Mechanical defect"?
-->'''Durkon''': I dunno, I count "able to be picked by a rogue" as a pretty major defect, aye?
** In the prequel book ''On The Origin Of [=PCs=]'', Roy (incorrectly) thought this of his father.
* Amorphs in ''Webcomic/SchlockMercenary'' may try to eat anything, shoot any fun, and ''might'' lie to your face... but when sharing memories THOSE MEMORIES WILL BE ACCURATE. Otherwise, what's the point?

* ''WebAnimation/{{Tonin}}'' character Fimose played the trope straight while trying to impress a girl. He told her he lived at a building worth $1.6 million in Brazilian currency. He actually rented an apartment at a building with 40 apartments and each one was worth $40,000. He also claimed to have studied at a school in Switzerland. "Switzerland" was the name of the street where his public school was. He claimed to have made an investment that might earn him $16 million. The so-called "investment" was buying a lottery ticket. He claimed to have a car collection. They were ''Hot Wheels'' toy cars. He claimed to have three Ferraris. There used to be four but his dog ate one. He claimed his dad worked with oil products. Said dad worked at a gas station. When asked if he worked at some world wide company, Fimose said his dad worked with the Arabs. The station's owners are Arabs. He claimed his mother used to be an international model before her marriage. She posed naked for a painter from Argentina.

* ''Franchise/CareBears'': Shreeky gave the impression she'd play the trope straight but it turned out to be a BaitAndSwitch moment. She did something that drove her Uncle No Heart enraged and told him she couldn't lie. Then she lied by pinning the blame on Mr. Beastley.
* This is Applejack's schtick in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', so much so that she's the bearer of the Element of Honesty. This, however, worked against her in "[[Recap/MyLittlePonyFriendshipIsMagicS2E14TheLastRoundup The Last Roundup]]", as she had been Pinkie Promised by Pinkie Pie to tell the other ponies as to why she wasn't coming back to Ponyville. She told them that she'd tell them after breakfast... then tried to get out of town by ''skipping'' breakfast. Didn't fool Pinkie for a second and the others have to chase her down to find out the truth.
** Applejack's honesty is also exploited by the Flim Flam Brothers in [[Recap/MyLittlePonyFriendshipIsMagicS4E21LeapOfFaith "Leap of Faith"]]. AJ has such a reputation for being honest that, when she gives a half-hearted admittance that the AllNaturalSnakeOil the brothers are selling probably made Granny Smith feel better, Flim and Flam jump on it and use her in promoting their tonic.
* ComicStrip/{{Popeye}} invokes this in an Creator/AlBrodax-produced cartoon where Wimpy escapes Brutus' wrath by [[ItMakesSenseInContext making himself invisible with vanishing cream.]] Popeye gets into the act with him, and as Brutus approaches:

* Mojo Jojo uses this on Blossom in ''WesternAnimation/ThePowerpuffGirls'' episode "Not So Awesome Blossom." Mojo is holding the Professor, Bubbles and Buttercup hostage in exchange for Blossom's servitude. When she counters "How do you know I won't lie?", Mojo responds "Because you're Blossom."
* This is [[WesternAnimation/RockyAndBullwinkle Bullwinkle the Moose]] in a nutshell. In the counterfeit box tops story arc, he says his mother told him to never tell a lie.
* ''WesternAnimation/SamuraiJack'' is so honest, it almost got him killed once. After helping rescue the Scotsman's wife from the Master of Hunt, he suggested she'd "need help", saying she was "quite large". Unfortunately, he seemed to have forgotten for the moment [[BerserkButton how sensitive she was about her weight,]] proven by the rather violent fit she threw when the villain called her fat. Long story short, this was one of the few times Jack had ''ever'' fled from someone in fear.
* ''WesternAnimation/TheSimpsons'': In "Homer vs. the Eighteenth Amendment", there was a moment Marge asked Homer to tell where he was going.
--> '''Homer:''' I'm not going to lie to you, Marge. ({{Beat}}) (Walks away)

** Ironically, while Washington was at best a mediocre general, he was an excellent spymaster and a superlative counterintelligence officer - both military specialties where an ability to lie with sincerity is a significant asset.

Contrast IGaveMyWord. Compare VillainsNeverLie.

* At the conclusion of ''Film/SmokeyAndTheBandit,'' the Bandit and Snowman make it to Atlanta with truckload of Coors beer followed by Sheriff Justice. Via CB radio, the Bandit tells Justice where he is when he's really detailing Big and Little Enos. But then he has a change of heart, saying he can't lie to Justice. He tells Justice to look over his left shoulder.

* ''Series/Omens'': Played with.
** [[OurDemonsAreDifferent Crowley]] is a demon, so lying is like his second nature, except he is not able to ever tell a lie to his [[BestFriend best friend]] ([[spoiler:and [[OneTrueLove one true love]]]]) [[OurAngelsAreDifferent Aziraphale]]:
-->'''Crowley:''' [[Hellhound The Hellhoud]] has found its master.

* The Claymores from ''Manga/{{Claymore}}'' have a very strong moral system and don't feel the need to lie or deceive. They are perfectly capable of doing so if they feel like it. That rarely happens, though.
* Iori in ''Anime/DigimonAdventure02'' initially refused to take the Digimental of Faith because he lied earlier in the episode getting help.
* Greed of ''Manga/FullmetalAlchemist'' considers it a matter of principle never to tell a lie. [[spoiler:In the end, he finds [[HeroicSacrifice one worth telling]]]].

* In ''Manga/DrStone'', Senku claims "Science doesn't lie", and neither does he when it comes to science, even in situations where doing so would benefit him. Early on, when Tsukasa holds Yuzuriha hostage and demands to know the formula for the "miracle water", Senku complies rather than giving him a false formula just to save his friend. When they're trying to sway Nikki to their side, she asks if they can bring back Lillian Weinberg's music; Gen encourages him to lie and say yes, but Senku admits that all music storage media from their time have long since crumbled into dust.
* ''Manga/MyHeroAcademia'': Ibara Shiozaki/Vine absolutely refuses to perform any kind of deceitful action, even if it would benefit her. Whenever her teammates need to act covertly or trick their opponents, they don't tell her the plan because they know she'll just blurt out the truth.

* ''ComicBook/{{Superman}}'':
** In ''ComicBook/Superman1939 #176'', Superman and ComicBook/{{Supergirl}} celebrate a Kryptonian holyday called the Day of Truth in which they ''have'' to speak nothing but the truth, no matter the cost. It is not an easy task because they are ''incredibly'' and rudely blunt when they are being honest. Also, several crooks ask Superman about his secret identity and his Fortress' location.
** In week 34 of the ''ComicBook/FiftyTwo'' series, some of Luthor's thugs kidnap a depowered Clark, drug him with truth serum, and ask him a question about Superman's secret identity. Specifically, they ask "[[spoiler:Why is the Man of Steel masquerading as Supernova]]"? He cracks up.
* In ''ComicBook/{{Lucifer}}'', the title character finds lies beneath him. As Mr. Easterman [[GreekChorus narrates]], "He doesn't lie at all. He tells you the exact, literal truth. And he lets you find your own way to hell."

* In ''Fanfic/ChildOfTheStorm'' and its sequels, Doctor Strange is distinguished by the fact that he never, ever tells a lie. Despite this, he still manages to be the series' premier MagnificentBastard, playing the rest of the cast, from ordinary humans to the Endless themselves, like a violin. This is because of a mind-boggling amount of future knowledge and like TheFairFolk, with his mastery of ExactWords and somewhat selective attitude to the truth, telling the literal truth is not the same as being honest. However, if he gives his word or makes a vow, he ''will'' keep it, no matter what it costs him, because it is quite literally the only thing that he has left. The implication that he might lie or break his word presses his BerserkButton sufficiently that he states that the person questioning him only gets a pass this once, and that because they're a justifiably frustrated and worried teenager. It is very heavily implied that if it was anyone else, he'd have killed them on the spot. While he's half mad at the time, it speaks volumes of how seriously he takes his word.
--> I am many things; among them, [[ManipulativeBastard a manipulator,]] [[WellIntentionedExtremist a murderer,]] [[HeWhoFightsMonsters perhaps even something of a monster.]] I have walked too many dark paths for too long to be anything else. But the one thing I am not and will never be is a liar.

* The 1941 comedy ''Film/NothingButTheTruth'' (based on a 1920 dramatization of a 1914 novel) stars Creator/BobHope as a stockbroker who bets $10,000 that he can go 24 hours without telling a single lie. Hilarity ensues as [[ColdTurkeysAreEverywhere seemingly endless opportunities for lying]] present themselves.

* ''Film/SupermanTheMovie'': KAl-El expressly states that he never lies.

* Creator/RobertAHeinlein:
** Star from ''Literature/GloryRoad''. She always tells the truth, but has no problem with misleading you. She also has no problem with letting ''you'' mislead ''yourself.'' Rufo even states this explicitly.
** Fair Witnesses in ''Literature/StrangerInAStrangeLand'', due to their conditioning as expert witnesses, will only tell the directly observed facts. This excludes subjective qualifiers, conjecture or analysis from their description. This gives them perfect eidetic memory and more legal credibility than audiovisual recordings, which can be forged. Jubal exemplifies this to Jill by calling his secretary over who is licensed as a Fair Witness and asking her what color the neighbor's house in the distance is. She responds "On this side it's white, boss."
* ''Literature/LumbanicoTheCubicPlanet'': When Ustrum doubts Vinca's sincerity, the little girl indignantly declares she never lies, which is because she is often punished by her father. Ustrum asks why her father would punish her for not lying, and Vinca replies she always confesses when she has misbehaved.
* One of the obnoxious behaviors of the Martians in Creator/FredricBrown's ''Martians, Go Home'' is spying on humans and blabbing their secrets. The fact that their stories always check out when someone tries to verify them just makes matters worse.
* The wizards in the ''Literature/YoungWizards'' series. When your job is reshaping reality with words, lying is a Bad Idea.
* Most of Creator/PiersAnthony's protagonists adhere to this rule at least to some degree.
* Wallace Wallace of ''Literature/NoMoreDeadDogs'' refuses to lie because his father was constantly telling whoppers when Wallace was a kid, which leads him to be incredibly blunt towards others. [[spoiler:He does tell Rachel a white lie at the end.]]
* ''Literature/RodAllbrightAlienAdventures'': Rod will not lie, even when aliens crash land in his room and eat his homework, a tale that he knows no one will believe. [[spoiler: He lies right to the face of a police officer at the end of the story to protect his alien friends.]]

* Lord Foul, the BigBad of ''Literature/TheChroniclesOfThomasCovenant'' always seems to tell the truth. The WordOfGod is that he thinks himself so superior to his enemies that he feels lying is beneath him. He is very good at saying things that are misleading, yet technically true, though.
** The Insequent will not tell a lie either.

* ''Literature/{{Discworld}}''
** 's Carrot Ironfounderssons good at this. Paraphrased: "If you do not let us in... well, I have my orders. And I won't like carrying them out. If it's any consolation, I'll be very ashamed later. But I will follow them." "I have armed guards!" "Believe me, that will only make it easier for me to obey." His orders? Walk away if they don't let them in willingly.
** ''Literature/TheTruth'': William de Worde refuses to lie, but he is good at using ExactWords to mislead people without actually lying to them. Like saying "I've just spoken to Commander Vimes, and I would like to see the room where the crime was committed," knowing that this would be taken to mean Commander Vimes gave him permission to do so.
* The Kencyr peoples in P.C. Hodgell's ''Literature/ChroniclesOfTheKencyrath'' series have a rigid honor code in which lying is one of the most serious offenses, for which a honorable death (suicide, or death in battle) is the only way to redeem oneself. This nature is known to others, as when Jame is called as a witness in a scene in ''God Stalk'':
-->"You know, it's an odd thing about these people: they never lie. And they will fight to the death to uphold their word. You there by the door, you guards, can you say the same? Will you do battle for your honor?"
-->The guards looked at Jame and Marc, then at each other. "No, sir," said the bigger of the two flatly. "We weren't paid enough for that."
* ''Literature/TheLordOfTheRings'':
** Éomer declares that "The men of Rohan do not lie, and so are not easily deceived."
** Faramir says he wouldn't use a falsehood to ensnare even an orc, though that doesn't mean he is above being MetaphoricallyTrue if necessary.
* The guest in the ''Literature/BlackWidowers'' story "Truth to Tell" by Creator/IsaacAsimov is a man who never lies, which ultimately supplies the solution to the mystery. Henry, who does not like to lie, pays very close attention to his ExactWords.
* In Creator/EdgarRiceBurroughs's ''[[Literature/JohnCarterOfMars The Gods of Mars]]'', Thuvan Dihn supports John Carter's claims because
-->"It is not a lie. This much have I learned of the Prince of Helium--he does not lie."
* Creator/DavidWeber's ''Literature/{{Safehold}}'':
** Because how honest (or not) he has been will come back at him when he inevitably has to reveal major secrets, Merlin Athrawes is ''extremely'' careful about this. He is not above using half-truths or explaining his abilities [[LiesToChildren in terms his Safeholdian counterparts will more easily grasp]], but he will do his utmost to avoid outright lying. A perfect example would be, when explaining the abilities granted by being a machine, he claims "to possess skills attributed to ''seijin,'' sages/warriors in legends." He allows people to call him ''seijin'', but never actually claims the title for himself.
** Later on, it becomes a significant factor in the propaganda battle between the Empire and the Church. The Charisians have done their best to restrict their propaganda to provable facts, regardless of whether anyone will believe them or not. On at least two occasions: Ahnzhelyk's files regarding Church corruption and the murders of vicars within Zion itself. Charisian leadership choose not to publish anything because they only have copies and not the original evidence in the case of the former and because there's an off-chance of Clyntahn's pulling a fast one and can disprove their claims in the case of the latter.
** In ''At the Sign of Triumph'' this becomes crucial when the propaganda broadsheets Owl's remotes tack up all over the Temple Lands [[spoiler:call on the people of Zion to rise up against the Inquisition]]. The Charisians' keeping the broadsheets limited to pure facts, compared to the Inquisition's constant lies and denials, it made it easy for people to decide what to do.

* In Creator/CSLewis's ''Literature/TheHorseAndHisBoy'', Shasta suggests to Corin various ways he could cover up the facts, but realizes it's impossible and says he will have to tell the truth. Corin scornfully says that of course he would have told the truth.
* In Creator/RobertEHoward's ''The Shadow Kingdom'' Literature/{{Kull}} insults a Pict by claiming Picts never tell the truth, even though they follow this trope.
* The [[OurElvesAreDifferent Marat]] from ''Literature/CodexAlera'' have little concept of lying, and no word for it. As such, being "deliberately mistaken" is an incredibly grave offense, and an accusation of it can lead to an honor duel.
* Michael from the ''Literature/KnightAndRogueSeries'' goes out of his way to be honest, even if it gets him in insane amounts of often not deserved trouble. It probably helps that he's also a terrible liar anyway, so there's no real temptation to fib, but he tries to prevent Fisk from being dishonest as well.
** On the other hand, on the rare occasion when he ''does'' lie (such as to protect someone else), his usual honesty makes the lie much more convincing.

* The titular Caine of ''Literature/TheActsOfCaine'' has a bit of a warped sense of honor, which has given him the well-deserved reputation that he would rather kill a man than lie to him. The last act of the first book hinges entirely on lies and deceit, which makes him very uncomfortable.
* In Creator/PoulAnderson's "[[Literature/TimePatrol Brave To Be A King]]", Manse listens to a story that is clearly MosesInTheBulrushes and so a hero legend -- but from a Persian, and he knows the Persians are fanatical about this.
* In ''Literature/TheSagaOfDarrenShan'', the vampaneze have a complex code of honour which, among other things, forbids them from lying. A vampaneze will never break this code, even when violently insane.

* British statesman Lord Chesterfield recommends being this in ''Literature/LettersToHisSon'': "I really know nothing more criminal, more mean, and more ridiculous than lying." (letter XIV)
** Also, he often pointed out how a honest friend who doesn't hesitate telling you about your flaws is better than a flatterer.
* In ''Literature/RachelGriffin'', [[HonorBeforeReason Nastasia]] at one point refuses to FeedTheMole because of this trope.
* Braxton "Bix" Rivers in Bruce Brooks' ''The Moves Make the Man''. He will go ballistic at the faintest suggestion of an untruth, even if it's a joke, takes obvious lies from others at face value on principle, and refuses to fake in basketball, hoping to win by playing an "honest" game. [[spoiler:By the end of the book, he has learned to fake, both in basketball and in real life.]]
* The Minds in [[Creator/IainBanks Iain M. Banks]]' [[Literature/TheCulture Culture]] series do not lie.
** "They dissemble, evade, prevaricate, confound, confuse, distract, obscure, subtly misrepresent and willfully misunderstand with what often appears to be a positively gleeful relish and are generally perfectly capable of contriving to give one an utterly unambiguous impression of their future course of action while in fact intending to do exactly the opposite, but they never lie. Perish the thought."
* In ''Literature/{{Pact}}'', most characters are magically bound to speak the truth. This is not the same as not being able to lie. Alister Behaim, however, tries his best to avoid the MetaphoricallyTrue mentality of most people and speaks with as much directness as possible, avoiding weasel words where he can, and comments that he's pretty sure that he's following the spirit of things better than many others.
* [[EvilOverlord The Lord Ruler]] from ''Literature/MistbornTheOriginalTrilogy'' has a reputation for never lying - after all, he's an omnipotent GodEmperor, so why would he ''need' to lie to get what he wants? [[spoiler: While he never tells an explicit lie on-page - even his rant about being TheChosenOne and the Avatar of God is true from his perspective - he is willing to mislead his followers about his true origins, so they don't uncover the secret of his power]].
* Creator/SpiderRobinson's story "Satan's Children" describes the societal effects of [[TruthSerum a drug that makes people tell the truth]]. Even after the drug wears off, users continue to tell the truth because they find that honesty [[GoodFeelsGood just feels better]].
* The title character of Creator/JamesFenimoreCooper's ''[[Literature/TheLeatherstockingTales The Deerslayer]]''.
--> Truth was the Deerslayer's polar star. He ever kept it in view, and it was nearly impossible for him to avoid uttering it, even when prudence demanded silence.
* The Houyhnhnms from ''Literature/GulliversTravels'' are fully capable of saying basic lies like "Black is white", but they cannot comprehend the ''point'' of using speech for miscommunication rather than communication.

* ''Literature/{{Ravirn}}'': Eris, as VillainsNeverLie, usually:
--> Why bother when the truth is usually so much more devastating?
* In Alexander Key's ''The Forgotten Door'' Jon is puzzled by the concept of a white lie because his people always tell the exact truth, no matter what the circumstances.
* Most light dweomer workers in the ''Literature/{{Deverry}}'' cycle have sworn an oath to always tell the truth. It is not required, however, and Nevyn decided it would be too inconvenient, so he didn't. Many people who know a bit about the light dweomer and deal with Nevyn fail to realise this.

* Loker on ''Series/LieToMe'' abides by "radical honesty," which means he not only always tells the truth, but he also blurts out whatever he's thinking, no matter how inappropriate that may be.

* ''Series/MarriedWithChildren'': In one ChristmasEpisode, Al and Griff were fired and spent the day trying other jobs. They regained their jobs by tricking their replacements into quitting. When Peggy asked Al how his day was, he said it started at the store and ended there.
* One PatientOfTheWeek on ''Series/HouseMD'' is a woman who will not lie to her daughter. House is astounded, since this challenges his "[[CatchPhrase everybody lies]]" philosophy.
* In an episode of ''Series/WouldILieToYou'', Vic Reeves has to claim that he once helped Dr Raj Persuad fix his computer. He doesn't even attempt to defend it and admits at once that he doesn't know who Raj Persuad is.

* ''Series/GameOfThrones'':
** Jon Snow refuses to lie to [[GodSaveUsFromTheQueen Cersei]] about taking her nemesis' side, even when it meant breaking a ceasefire that was necessary to band their collective forces against the hordes of the undead.
--->'''Tyrion''': I'm glad you chose to bend the knee. I would have advised it. But would it kill you to learn to lie, just a little bit?\\
'''Jon''': I'm not going to lie, nor am I going to keep secrets. Tell me my father died because of this way of thinking, but when enough people make enough lies and secrets, words lose their meaning, and then there's no meaning, only bigger and better lies.
*** On the other hand, Jon did tell Stannis something that could either be interpreted as a lie or at least a blatant exaggeration earlier on. Stannis had just invaded the wildling camp, where Jon was meeting to arrange a cease-fire with Mance Rayder. They come out, and are captured by Stannis' men. Stannis then asks Jon what Eddard Stark would do. Jon praises Mance as an honorable man who treated him well as a prisoner (Jon and his companion were force-marched and verbally abused, Jon had to kill his friend to convince the wildlings he was a defector): Mance raises an eyebrow subtly, but wisely plays along. Then Jon claims that Eddard Stark would have shown mercy, when "merciful" isn't among the adjectives most would use to describe the late Lord of Winterfell. The actual truth is that Jon simply refuses to lie to save his own skin. [[spoiler: As evidenced by how he originally died.]] However, he will gladly lie-and do it well-if it's to save someone else. Which makes what Jon told Tyrion at least not quite the truth.
** Stannis is very frank; as exemplified by his stern objection to Robert being called "my ''beloved'' brother" in a missive, and by the confession of his adultery to his wife.
* ''Series/Lucifer2016'': Despite his moniker as "The Prince of Lies", Lucifer is always completely honest about being the Devil, but [[CassandraTruth nobody ever believes him]]. If anything, he's actually ''averse'' to lying and often drifts into oversharing. The closest he gets to being dishonest is by omitting details from otherwise true stories, e.g. when he tells Chloe that a shipping container that was stolen from him contains Russian nesting dolls (which it does), but leaves out that it also contains his severed angelic wings. In a particularly heartbreaking moment, Trixie demands that Lucifer be the one to tell her that [[spoiler:her father, Dan, really is dead]] because she knows he won't lie to protect her feelings. Lucifer's unfailing honesty is so well known to those around him that it becomes one of the ways to tell him apart from his twin brother [[ArchangelMichael Michael]]. When the latter tries to pull off a TwinSwitch he has to come up with an elaborate excuse about why "Lucifer" is suddenly willing to lie.

* In ''TabletopGame/GeniusTheTransgression'' the [[MadScientist Peerage]] is steadfastly against lying, though the attitude is fading. This is because the oldest and most respected organization of mad scientists in the world traces it's origins back to a Zoroastrian philosophy cult.

* The Avatar, in the ''VideoGame/{{Ultima}}'' series. At least, you play that way if you want to win. S/He is not perfect, either. You lose Honesty-points if you try to claim "I never lie."
* The Ur-Quan Kzer-Za in ''VideoGame/StarControl 2''. They claim that lying is for the weak, and the Ur-Quan are NOT weak.

* Kirei Kotomine in ''VisualNovel/FateStayNight'' won't lie to you. He's very fond of {{False Reassurance}}s and half truths though. 'A Servant is still hanging around from the last war? As the supervisor I cannot ignore that!' [[spoiler:He's shocked because after telling Gilgamesh not to show himself, he did so anyway. So he doesn't ignore it, he scolds Gilgamesh for almost blowing his cover.]] As noted in ''VisualNovel/FateHollowAtaraxia'' it also applies to most Servants by default: Their pride doesn't let them.
* 343 Guilty Spark from ''Franchise/{{Halo}}'' might fall into this trope, or he might fall into CannotTellALie, depending on how you think he was programmed and to what degree his rampancy has proceeded. Either way, nothing he ever says is untrue. He does withhold inconvenient facts if nobody asks about them, but it's more likely that it just doesn't occur to him to explain; he simply takes it for granted that anybody attempting to activate Halo would know what they were doing.
* ''Franchise/MassEffect'':
** Turians are described as such in the codex, as a matter of personal honor. A turian who commits a crime will do everything he can to avoid getting caught, but if flat-out asked, will freely admit it. Turian culture has a thing about personal responsibility. It is mentioned that a turian using illegal recreational drugs while off-duty in a way that wouldn't halter their ability to do their job and duty, no turian would blink an eye. This also causes turian arc villains in the series being seriously prone to start giving {{MotiveRant}}s. There is also some FridgeBrilliance / AllThereInTheManual: adult turians are given TribalFacePaint signifying their colony of origin from before their Unification War, and people that dishonor their ancestors are refused their Face Paint. It is mentioned that the slur ''bare-faced'' is used amongst turians to describe untrustworthy individuals (and politicians). The two bare-faced turians we meet in the games? The BigBad Saren from ''VideoGame/MassEffect1'' and the ArcVillain Warden Kuril in ''VideoGame/MassEffect2''.
** According to Legion, the geth understand the concept of deception, but don't practice it among themselves. Their "species" becomes more intelligent by sharing information with each other, so the idea of deliberately withholding information from another geth is simply unthinkable. This is one reason Legion is disturbed by the heretic geth: it discovers that they are consciously lying to the mainstream geth civilization, in preparation for an attack. Legion is horrified by this idea, and cannot understand what kind of thinking would lead the heretics to act that way.

* Ishida Mitsunari from ''VideoGame/SengokuBasara'' never lies, or indeed speaks in ''anything'' but BrutalHonesty, due to being too socially blunt. This is actually one of his few virtues, as he's a [[RoaringRampageOfRevenge screaming whirlwind of bloody vengeance]] most of the time.

* Zotul Kulle in ''VideoGame/DiabloIII'' makes many cryptic statements as you assist him, which since he is an unrepentant evil wizard, makes it all suspect, but when he's directly accused of lying he denies it, simply saying he finds the truth far more entertaining.
* The Sacaeans in ''VideoGame/FireEmblemElibe'' are known for this.

* Durkon of ''Webcomic/TheOrderOfTheStick'' is a Lawful Good dwarven cleric, so it makes sense that he's reticent about lying, especially when dealing with other Lawful Good types, as seen in [[http://www.giantitp.com/comics/oots0264.html this]] strip. [[MetaphoricallyTrue Technically, he doesn't.]]
-->'''Durkon''': I can swear on Thor's beard that the ''five'' of us never left our cells.
-->'''Miko''': Then what of the cell doors? How did they become unlocked?
-->'''Durkon''': I cannae lie to ye. 'Twas a mechanical defect.
-->'''Roy''' [aside]: "Mechanical defect"?
-->'''Durkon''': I dunno, I count "able to be picked by a rogue" as a pretty major defect, aye?
** In the prequel book ''On The Origin Of [=PCs=]'', Roy (incorrectly) thought this of his father.

* In ''Webcomic/ElGoonishShive'', in one universe, one of the rules governing Immortals is a prohibition on lying. If one does, this will be sensed, and said liar can expect to face the wrath of the rest of its kind. This rule however notably does not apply to the main universe the story takes place in and this fact [[http://egscomics.com/comic/2015-09-28 is exploited]].

* ''WesternAnimation/TheSimpsons'': In "Homer vs. the Eighteenth Amendment", there was a moment Marge asked Homer to tell where he was going.
--> '''Homer:''' I'm not going to lie to you, Marge. ({{Beat}}) (Walks away)
* ''WesternAnimation/SamuraiJack'' is so honest, it almost got him killed once. After helping rescue the Scotsman's wife from the Master of Hunt, he suggested she'd "need help", saying she was "quite large". Unfortunately, he seemed to have forgotten for the moment [[BerserkButton how sensitive she was about her weight,]] proven by the rather violent fit she threw when the villain called her fat. Long story short, this was one of the few times Jack had ''ever'' fled from someone in fear.

* Mojo Jojo uses this on Blossom in ''WesternAnimation/ThePowerpuffGirls'' episode "Not So Awesome Blossom." Mojo is holding the Professor, Bubbles and Buttercup hostage in exchange for Blossom's servitude. When she counters "How do you know I won't lie?", Mojo responds "Because you're Blossom."

* ''Anime/PuellaMagiMadokaMagica'': Kyuubey never lies. But he has absolutely no qualms about [[YouDidntAsk omitting all kinds of useful information]] and [[ExactWords phrasing things in misleading ways]], whenever he feels that be completely truthful would put him at a disadvantage. Case in point, When Kyoko asks if there is any way to [[spoiler:return Sayaka to human form]], Kyubey states that there's no precedent for it. Later, when asked the same question by Homura, after Kyoko's plan to save Sayaka has failed spectacularly, Kyubey straight up tells her that it's impossible. His answer to Kyoko was ''technically'' correct, but was also deliberately worded in a manner that baited her into believing that there might be a way.

* The titular character of ''Manga/LiarSatsukiCanSeeDeath'', ironically for someone who has earned a reputation for being a CompulsiveLiar, is this in reality. When her friends challenge her to lie about even relatively minor and harmless things, she still refuses to do so--and when she at one point lies about ''jumping off a building'' as part of a scheme to save someone's life, she ''actually goes through with it'' solely because doing otherwise would make her a liar. As it turns out, she has some major-league trauma relating to the one time in her past that she ''did'' tell a lie.
