->''"Everyone suspects himself of at least one of the cardinal [[VirtueViceCodification virtues]], and this is mine: I am one of the few honest people that I have ever known."''
-->-- '''[[UnreliableNarrator Nick Carraway]]''', ''Literature/TheGreatGatsby''

When a character makes a conscious decision to be honest they Will Not Tell A Lie.

This is different from CannotTellALie in that nothing is forcing the character to be truthful besides their own will. This could be for different reasons. It could be a moral decision, or they could have an aversion to lying. Or they could get a [[PinocchioNose noticeable tic]] when under the stress of lying, or otherwise be [[BadLiar bad at lying]] so it defeats the purpose.

Either way, these are the characters who make an honest effort to be honest. This may cause them to become [[EmbodimentOfVirtue narratively associated with honesty as an ideal]].

As with CannotTellALie, it is possible that a character who follows this trope will decide to speak in [[HalfTruth half-truths]], and pull the YouDidntAsk card every time they get the chance. A character who functions like this may do so because it's more fun, or because it's easier to manipulate people when you are telling the truth. They are able to tell half-truths and omit important information, allowing for FalseReassurance and even MaliciousSlander and acting as a sort of TechnicalPacifist ConsummateLiar.

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.

Sometimes a sitcom plot, wherein a normally ConsummateLiar pledges to truth-telling. The plot nearly always will have them being accused of breaking their promise, [[CassandraTruth even when they aren't]]. Another frequent situation is the character's idea of being honest seeming to be unnecessarily hurtful, rather than simply telling the truth, "Does this make me look fat?" "Well, you want the truth? You look ''terrible''."

[[folder:Anime and Manga]]
* Duo Maxwell of ''GundamWing''. His motto is even "I may run and hide, but I'll never tell a lie".
* In ''Manga/MahouSenseiNegima'', Chao Lingshen states numerous times that "Martians don't tell lies." Of course, this doesn't prevent her from ''withholding'' all sorts of information...
** This might actually be ''CannotTellALie'', depending on the story behind this fact, but since it's never really explained, I'm putting it here.
* The Claymores from ''{{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 broke this rule 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]]]].
* ''Anime/PuellaMagiMadokaMagica'': Kyuubey never lies. He just [[YouDidntAsk omits all kinds of useful information]], and [[ExactWords phrases things in misleading ways]].

[[folder:Comic Books]]
* Comicbook/{{Superman}}. In the 1979 film he expressly states that he never lies. Presumably if anyone ever thought to ask him outright, "What is your secret identity?" or "Are you Clark Kent?", he could just refuse to answer.
** An enterprising villain could just ask every Caucasian male citizen he/she meets "Are you Superman?". But that'd take a while, and just because ''he's'' not willing to lie doesn't mean that [[IAmSpartacus other people won't]].
** 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]]"? [[CrowningMomentOfFunny 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."
* The title character of ''ComicStrip/DanDare'' absolutely refuses to lie, making him unusually moral even by 50s standards.
** In the story Prisoners of Space, this paid off superbly: Dan told the Mekon he'd fixed a limpet mine to his flagship, and, even though they couldn't find it, the Treens still abandoned ship and surrendered because they ''knew'' Dan was telling the truth.
* [[{{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.

[[folder:Film]]
* The 1941 comedy ''Nothing But the Truth'' (based on a 1920 dramatization of a 1914 novel) stars 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.
** This movie was partially remade as the 1997 JimCarrey vehicle ''Film/LiarLiar'', which puts more of a supernatural CannotTellALie twist on the same premise.
* In ''FindingNeverland'', James refuses to lie to Peter, who refuses to believe him since Peter believes that adults are never honest with children about the serious stuff.
* The time-displaced hero of ''KateAndLeopold'' considers it dishonorable to lie, even when the truth is likely to be disbelieved at best, and have him committed to a mental health facility at worst.
* 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.

[[folder:Literature]]
* Nick Carraway from ''TheGreatGatsby''-- see the page quote. Although he may not be telling the exact truth, which isn't much better.
* 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."
* One of the obnoxious behaviors of the Martians in 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 PiersAnthony's protagonists adhere to this rule at least to some degree.
* Wallace Wallace of ''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.]]
* 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.
* The [[OurElvesAreBetter Sithi]] from ''MemorySorrowAndThorn'' not only don't lie but seem to have trouble grasping the concept of lying. They do tend to talk a lot without saying much when they don't want to give away the truth.
* ''Literature/{{Discworld}}'''s Carrot Ironfoundersson.
-->'What's gotten into them?'
-->'Hard to say, sir,' said Carrot. Vimes shot him a glance. Carrot had been raised by dwarfs. He also, if he could possibly avoid it, never told a lie.
-->'That isn't the same as ''I don't know'', is it?' he said.
-->The captain [Carrot] looked awkward.
---> -- ''Discworld/TheFifthElephant''
** Carrot's 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.
* 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."
* "The men of Rohan do not lie, and so are not easily deceived." (From ''TheTwoTowers''; sadly this line did not make it into TheMovie.)
** Faramir says he wouldn't use a falsehood to ensnare even an orc, though that doesn't mean he is above using a HalfTruth if necessary.
* The guest in ''TheBlackWidowers'' story "Truth to Tell" by Creator/IsaacAsimov is a man who never lies, which ultimately supplies the solution to the mystery.
* In Creator/EdgarRiceBurroughs's ''[[JohnCarterOfMars The Gods of Mars]]'', Thuvan Dihn support John Carter's claims because
-->''It is not a lie. This much have I learned of the Prince of Helium--he does not lie.''
* Because how honest (or not) he has been will come back at him when he inevitably has to reveal major secrets, Merlin Athrawes in Creator/DavidWeber's ''Literature/{{Safehold}}'' series 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 chose 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).
* ''Literature/LesMiserables'': Sister Simplice is this trope to the extreme. Also, Inspector Javert.
* Seleneans and Zaldans in the StarTrekNovelVerse. 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 isnít 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 Creator/CSLewis's ''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'' {{Kull}} insults a Pict by claiming Picts never tell the truth, even though they follow this trope.
* The [[OurElvesAreBetter 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 ''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.
* In Albert Camus' existential novel ''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.
--> '''Judge''': Why did you kill the arab?
--> '''Meursault''': ... Because of the sun!
* 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 MosesInTheBullrushes and so a hero legend -- but from a Persian, and he knows the Persians are fanatical about this.
* In ''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.
* In 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.
* 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.Ē "
* 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 HalfTruth 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.

[[folder:Live Action TV]]
* ''Series/BabylonFive'':
** The Minbari like to claim this, but the rule has a wide range of exceptions, the biggest one being to preserve another's honor. 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.
* 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.
* 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.
* ''{{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."
* ''PushingDaisies'' has a team of lawyers who refuse to lie for religious reasons. It doesn't work very well.
* Maura Isles from ''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]].
* Clark in ''{{Smallville}}''. He usually changes the subject or says something true but irrelevant rather than give an outright lie. As in:
-->'''Perry White:''' This kid just picked up and threw a tractor!
-->'''Clark:''' You've been drinking too much, Mr. White.
** Or when he and Lois are, unknown to the other, WorkingTheSameCase at a strip club:
-->'''Lois (as a stripper):''' What are you doing here?
-->'''Clark (as a patron):''' What are ''you'' doing here?
* From ''Franchise/StarTrek'':
** Betazoids in ''Series/StarTrekTheNextGeneration'' seem to have this as a cultural trait. They are not averse to joking, however.
*** Well, when your society can read minds, lying is sort of pointless, right?
** 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.
** Similarly, Vulcans. On the other hand, Spock was known to "exaggerate", and even tell outright falsehoods, on numerous occasions. Then again, Spock ''is'' half human. Humans can and do lie frequently. And anyone who's hung around with Kirk a while is no stranger to cheating.
*** Vulcans appear to be more of a race [[InformedAttribute that claims to never lie]], however they have been found lying on a number of occasions, making you wonder. After all, if they can lie, then they can lie about not lying.
*** It's a running gag in the ExpandedUniverse that anyone who believes that Vulcans don't lie, doesn't know Vulcans. They ''prefer'' not to lie, but they will if they have to.
*** Aptly displayed in the most recent movie 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.
*** Or the classic example that spawned all the others:
---> Saavik: You lied!
---> Spock: I exaggerated.
** Most Vulcans are logical beings so if lying would be the most logical course of action in the situation, they will. The fact that they're believed not to be capable of it makes them fairly good spies and infiltrators.
*** As indeed they do. When they are not using code that involves exchanging a smaller time-unit for a larger one (Spock's exaggeration) or implying something untrue while avoiding outright stating it (Old Spock's implication).
*** This quote comes to mind:
---> 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.
** WordOfGod states that Ziyal in ''Series/StarTrekDeepSpaceNine'' was a woman who never lied. It was one of the reasons why they decided to pair her up with Garak (someone who never tells the truth). They thought it would have an air of [[StarCrossedLovers tragedy]] to put them together. In the show itself, if Ziyal didn't want to tell the truth, she'd say nothing at all or talk about other subjects.
** In ''Series/StarTrekVoyager'' Janeway claims this about Q. The ''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.
* 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 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.
* The game show ''ToTellTheTruth'' centers around this as it pits three people all claiming to be a person of some importance or significant feat. One is telling the truth of who he/she really is; the other two could be telling the truth regarding what the person has done as a means to throw off the questioning panel but mainly they're fabricating.

* The protagonist of many PowerMetal songs, especially ManOwaR. For example ManOwaR's ''Hymn of the immortal Warriors'' ("...Great were his deeds/All his words were true/He lived and died/A man of Honour..."). Power Metal protagonists are often the strongest, smartest, most honourable and truest LawfulGood heros possible, fighting ForGreatJustice, honour and Metal.

[[folder:Tabletop Games]]
* In ''{{GURPS}}'' the "self imposed mental disadvantage" Truthfulness is for characters that hate lying and are obvious when they try.
* The Fire-Touched of ''TabletopGame/WerewolfTheForsaken'' are bound to the rule "Never let a false statement lie". Since this would presumably include your ''own'' false statements...
* 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.

* Bousille, the main character of the French-Canadian play ''Bousille et les justes''. This trait leads him to his ultimate tragedy, as he is grappling between telling the truth and lying to protect the reputation of the family for which he is testifying. In the end, he [[spoiler:tells the lie, but ultimately feels so guilty about himself that he hangs himself in the garage]].

* The Avatar, in the ''{{Ultima}}'' series. At least, you play that way if you want to win.
** Mind you, s/he is not perfect, either. You lose Honesty-points if you try to claim "I never lie."
* The Ur-Quan Kzer-Za in ''StarControl 2''. They claim that lying is for the weak, and the Ur-Quan are NOT weak.
* ''Franchise/AceAttorney'': Byrne Faraday writes in Kay's 'promise journal' that she should not tell lies. When she actually does tell one it's only because she broke another promise (talking to a stranger) and is upset that he might find out. [[spoiler:Of course he can't, being dead and all, and her lie nearly gets Gumshoe arrested for Faraday's murder.]] Later on she not only refuses to lie but runs her mouth off about being the Yatagarasu [[WhatAnIdiot in front of Interpol agents actively looking for the Yatagarasu]].
* Kirei Kotomine in ''[[VisualNovel/FateStayNight Fate/stay night]]'' 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 Fate/hollow ataraxia]] 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 whether you believe he's gone [[AIIsACrapshoot rampant]], or if he's just always been that way. Either way, nothing he ever says is untrue. He will withhold inconvenient facts if nobody asks about them, however.
** It's more likely that explaining the rings' purpose just doesn't occur to him. He simply takes it for granted that anybody attempting to activate the rings would know what they do.
* Turians in ''Franchise/MassEffect'' 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 prominent to start giving {{MotiveRant}}s.
** There is also some FridgeBrilliance / AllThereInTheManual: Adult Turians are given a 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 an politician. The two Bare Faced Turians we meet in the Games? The BigBad Saren from MassEffect1 and the ArcVillain Warden Kuril in MassEffect2. Note that either of them had every chanse to paint their face in any pattern of their liking, exept '''that they didn't.'''
* The Great Mizuti of ''BatenKaitos'' never lies nor tricks. [[JediTruth Maybe only sometimes. Rarely. Once in a blue moon]].
* 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.
* 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?
** Here's another interesting detail about him: He is an SNKBoss, but in his first appearance he claims that he isn't good at fighting. How did he manage to tell that [[BlatantLies Blatant Lie]] without breaking character? Well, aside from never telling lies, he is also very accomplished in telling {{Half Truth}}s, or conveniently "forgetting" to include certain insignificant details that might prove vital to a person's continued existence. Also, he's the [[Pantheon/{{Mentalism}} God of Trolling]]... i.e., he just said that while he doesn't consider himself good at fighting, the majority of the cast still suck donkey balls compared to him, seeing as [[spoiler:he's actually one of the Six Heroes and has only ever tasted defeat by other heroes[[note]]Nine sealed him for killing Jubei's brother, Hakumen managed to overpower him then threw themselves together to the Boundary...[[/note]]]]. So, while he doesn't necessarily say the truth, the whole truth and nothing but the truth, he doesn't technically fib and pretty much confesses without ''any'' provocation that he gave [[AntiHero Ragna]] his DarkAndTroubledPast ForTheEvulz.
** Though subverted that despite his claims of disliking lies and constantly claiming that the world is nothing but lies... he's ''not'' above lying if being honest would lead to his schemes and plans getting revealed too early. For instance, when he attempted to get rid of Makoto for knowing too much of his plan in Jin's story, his claim was merely 'to discipline Makoto'. The {{Hypocrite}}.
*** FromACertainPointOfView one ''could'' say that he was being truthful then, too. Offing someone isn't a diciplinary session that would teach anyone a lesson they'd have much use for, but it sure as hell gets the point across that they shouldn't have done it, and will never do it again...
*** Also in a subversion above all else, the definition of 'lies' in Terumi's mind far differs from what humans think to be lies. His definition of truth is only 'Despair', everything else are lies. Unfortunately for him, everyone knew that such claim is a big lie and [[ItsAllAboutMe only he thinks like that]]. So he may not tell a lie indeed... Just that his brand of lie that he won't tell.
* VillainProtagonist Kain from the ''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.
* 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. [[FromACertainPointOfView 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/GunnerkriggCourt'', this is said to be true of [[TheTrickster Coyote]]. He does not lie, and if he makes a promise, you can be certain he will follow through on it. None of this means he is trustworthy in the slightest. He also enjoys being deliberately obtuse when answering questions:
-->'''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.
* Doc Scratch of ''Webcomic/HomeStuck'' claims that he does not lie ("I am ''allowed'' to do whatever I want. I ''choose'' not to lie."). After reaching the wrong conclusion based on ExactWords, Rose challenges him on whether lies of omission count:
-->'''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.]]

* Chargesdotcomdotbr character Fimose played the trope straight while trying to impress a girl. He told her he lived at a building worth $ 1.6mil (Brazilian currency). He actually lived at a rented apartment at a building with 40 apartments and each apartment was worth $ 40thousand. He also claimed to have studied at a school in Switzerland. "Switzerland" was the name of the street where the public school was. He claimed to have made an investment that might earn him $ 16mil. The so-called "investment" was buying a lottery ticket. He claimed to have a car collection. They were HotWheels 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 to a painter from Argentina.

* ''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.
* ''WesternAnimation/TheSimpsons'': In "Homer vs. the Eighteenth Amendment", there was a moment Marge asked Homer to tell where he was going. Homer said he'd not lie to her and then he left without saying anything else.
* ''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.
* 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.
* Mojo Jojo uses this on Blossom in ''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."
* {{Popeye}} invokes this in an Al Brodax-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:
-->'''Brutus:''' Popeye, have you seen that moocher Wimpy?\\
'''Popeye:''' Brutus, ya knows I never tells a lie. Nope. I hasn't seen him today.

* [[DichterUndDenker Immanuel Kant]] is somewhat known for having stated that, because the categorical imperative requires following absolute moral rules in every situation, and not lying is one, it would even be morally wrong to lie to a murderer inquiring the location of an intended victim. Some interpreters have softened this in different ways, including at least by saying he meant it would merely be regrettable to have to do so or pointing out that that doesn't mean you have to tell the truth either.
* The [[http://en.wikipedia.org/wiki/Doctrine_of_mental_reservation doctrine of mental reservation]] is one of the reasons the word "jesuitical" has the connotations it does.
* MarkTwain once claimed that he Will Not Tell A Lie, which made him morally superior to George Washington, who merely [[CannotTellALie couldn't]].
* As told in her sister's memoirs, Nollie ten Boom. A veritable saint, like the rest of her family, but lacking the common sense to understand that some lies are acceptable when you are hiding people from the Nazis.
