A lie is an assertion that is believed to be false, typically used with the purpose of deceiving or misleading someone. [1] [2] [3] The practice of communicating lies is called lying. A person who communicates a lie may be termed a liar. Lies can be interpreted as deliberately false statements or misleading statements, though not all statements that are literally false are considered lies – metaphors, hyperboles, and other figurative rhetoric are not intended to mislead, while lies are explicitly meant for literal interpretation by their audience. Lies may also serve a variety of instrumental, interpersonal, or psychological functions for the individuals who use them.
Generally, the term "lie" carries a negative connotation, and depending on the context a person who communicates a lie may be subject to social, legal, religious, or criminal sanctions; for instance, perjury, or the act of lying under oath, can result in criminal and civil charges being pressed against the perjurer.
Although people in many cultures believe that deception can be detected by observing nonverbal behaviors (e.g. not making eye contact, fidgeting, stuttering, smiling) research indicates that people overestimate both the significance of such cues and their ability to make accurate judgements about deception. [4] [5] More generally, people's ability to make true judgments is affected by biases towards accepting incoming information and interpreting feelings as evidence of truth. People do not always check incoming assertions against their memory. [6]
The potential consequences of lying are manifold; some in particular are worth considering. Typically lies aim to deceive, so the hearer may acquire a false belief (or at least something that the speaker believes to be false). When deception is unsuccessful, a lie may be discovered. The discovery of a lie may discredit other statements by the same speaker, thereby staining that speaker's reputation. In some circumstances, it may also negatively affect the social or legal standing of the speaker. Lying in a court of law, for instance, is a criminal offense (perjury). [37]
Hannah Arendt spoke about extraordinary cases in which an entire society is being lied to consistently. She said that the consequences of such lying are "not that you believe the lies, but rather that nobody believes anything any longer. This is because lies, by their very nature, have to be changed, and a lying government has constantly to rewrite its own history. On the receiving end you get not only one lie –a lie which you could go on for the rest of your days –but you get a great number of lies, depending on how the political wind blows." [38]
The question of whether lies can be detected reliably through nonverbal has been the subject of frequent study. While people in many cultures believe that deception can be indicated by behaviors such as looking away, fidgeting, or stammering, this is not supported by research. [4] [5] A 2019 review of research on deception and its detection through nonverbal behavior concludes that people tend to overestimate both the reliability of nonverbal behavior as an indicator of deception, and their ability to make accurate judgements about deception based on nonverbal behavior. [4] [39]
Polygraph "lie detector" machines measure the physiological stress a subject endures in a number of measures while giving statements or answering questions. Spikes in stress indicators are purported to reveal lying. The accuracy of this method is widely disputed. In several well-known cases, application of the technique has been shown to have given incorrect results.[ examples needed ] Nonetheless, it remains in use in many areas, primarily as a method for eliciting confessions or employment screening. The unreliability of polygraph results is the basis of the exclusion of such evaluations as admissible evidence in many courts, and the technique is generally perceived to be an example of pseudoscience. [40]
A recent study found that composing a lie takes longer than telling the truth and thus, the time taken to answer a question may be used as a method of lie detection. [41] Instant answers with a lie may be proof of a prepared lie. A recommendation provided to resolve that contradiction is to try to surprise the subject and find a midway answer, not too quick, nor too long. [42]
Utilitarian philosophers have supported lies that achieve good outcomes – white lies. [43] In his 2008 book, How to Make Good Decisions and Be Right All the Time , Iain King suggested a credible rule on lying was possible, and he defined it as: "Deceive only if you can change behaviour in a way worth more than the trust you would lose, were the deception discovered (whether the deception actually is exposed or not)." [44]
Stanford law professor Deborah L. Rhode articulated three rules she says ethicists generally agree distinguish "white lies" from harmful lies or cheating: [45]
Aristotle believed no general rule on lying was possible, because anyone who advocated lying could never be believed, he said. [46] The philosophers St. Augustine, St. Thomas Aquinas, and Immanuel Kant, condemned all lying. [43] According to all three, there are no circumstances in which, ethically, one may lie. Even if the only way to protect oneself is to lie, it is never ethically permissible to lie even in the face of murder, torture, or any other hardship. Each of these philosophers gave several arguments for the ethical basis against lying, all compatible with each other. Among the more important arguments are:
In Lying , neuroscientist Sam Harris argues that lying is negative for the liar and the person who is being lied to. To tell lies is to deny others access to reality, and the harm of lying often cannot be anticipated. The ones lied to may fail to solve problems they could have solved only on a basis of good information. To lie also harms oneself, making the liar distrust the person who is being lied to. [47] Liars generally feel badly about their lies and sense a loss of sincerity, authenticity, and integrity. Harris asserts that honesty allows one to have deeper relationships and to bring all dysfunction in one's life to the surface.
In Human, All Too Human , philosopher Friedrich Nietzsche suggested that those who refrain from lying may do so only because of the difficulty involved in maintaining lies. This is consistent with his general philosophy that divides (or ranks) people according to strength and ability; thus, some people tell the truth only out of weakness.
A study was conducted by the University of Nottingham, released in 2016, which utilized a dice roll test where participants could easily lie to get a bigger payout. The study found that in countries with high prevalence of rule breaking, dishonesty in people in their early 20s was more prevalent. [48]
Possession of the capacity to lie among non-humans has been asserted during language studies with great apes. In one instance, the gorilla Koko, when asked who tore a sink from the wall, pointed to one of her handlers and then laughed. [49]
Deceptive body language, such as feints that mislead as to the intended direction of attack or flight, is observed in many species. A mother bird deceives when she pretends to have a broken wing to divert the attention of a perceived predator – including unwitting humans – from the eggs in her nest, instead to her, as she draws the predator away from the location of the nest, most notably a trait of the killdeer. [50]
It is asserted that the capacity to lie is a talent human beings possess universally. [55]
The evolutionary theory proposed by Darwin states that only the fittest will survive and by lying, we aim to improve other's perception of our social image and status, capability, and desirability in general. [56] Studies have shown that humans begin lying at a mere age of six months, through crying and laughing, to gain attention. [57]
Scientific studies have shown differences in forms of lying across gender. Although men and women lie at equal frequencies, men are more likely to lie in order to please themselves while women are more likely to lie to please others. [58] The presumption is that humans are individuals living in a world of competition and strict social norms, where they are able to use lies and deception to enhance chances of survival and reproduction.
Stereotypically speaking, David Livingstone Smith asserts that men like to exaggerate about their sexual expertise, but shy away from topics that degrade them while women understate their sexual expertise to make themselves more respectable and loyal in the eyes of men and avoid being labelled as a ‘scarlet woman’. [58]
Those with Parkinson's disease show difficulties in deceiving others, difficulties that link to prefrontal hypometabolism. This suggests a link between the capacity for dishonesty and integrity of prefrontal functioning. [59]
Pseudologia fantastica is a term applied by psychiatrists to the behavior of habitual or compulsive lying. Mythomania is the condition where there is an excessive or abnormal propensity for lying and exaggerating. [60]
A recent study found that composing a lie takes longer than telling the truth. [42] Or, as Chief Joseph succinctly put it, "It does not require many words to speak the truth." [61]
Some people who are not convincing liars truly believe they are. [62]
The Old Testament and New Testament of the Bible both contain statements that God cannot lie and that lying is immoral (Num. 23:19, [63] Hab. 2:3, [64] Heb. 6:13–18). [65] Nevertheless, there are examples of God deliberately causing enemies to become disorientated and confused, in order to provide victory (2 Thess. 2:11; [66] [67] 1 Kings 22:23; [68] Ezek. 14:9). [69]
Various passages of the Bible feature exchanges that assert lying is immoral and wrong (Prov. 6:16–19; Ps. 5:6), (Lev. 19:11; Prov. 14:5; Prov. 30:6; Zeph. 3:13), (Isa. 28:15; Dan. 11:27), most famously, in the Ten Commandments: "Thou shalt not bear false witness" (Ex. 20:2–17; Deut. 5:6–21); Ex. 23:1; Matt. 19:18; Mark 10:19; Luke 18:20 a specific reference to perjury.
Other passages feature descriptive (not prescriptive) exchanges where lying was committed in extreme circumstances involving life and death. Most Christian philosophers might argue that lying is never acceptable, but that even those who are righteous in God's eyes sin sometimes. Old Testament accounts of lying include: [70]
In the New Testament, Jesus refers to the Devil as the father of lies (John 8:44) and Paul commands Christians "Do not lie to one another" (Col. 3:9; cf. Lev. 19:11). In the Day of Judgement, unrepentant liars will be punished in the lake of fire. (Rev. 21:8; 21:27).
Augustine of Hippo wrote two books about lying: On Lying (De Mendacio) and Against Lying (Contra Mendacio). [72] [73] He describes each book in his later work, Retractationes. Based on the location of De Mendacio in Retractationes, it appears to have been written about AD 395. The first work, On Lying, begins: "Magna quæstio est de Mendacio" ("There is a great question about Lying"). From his text, it can be derived that St. Augustine divided lies into eight categories, listed in order of descending severity:
Despite distinguishing between lies according to their external severity, Augustine maintains in both treatises that all lies, defined precisely as the external communication of what one does not hold to be internally true, are categorically sinful and therefore, ethically impermissible. [74]
Augustine wrote that lies told in jest, or by someone who believes or opines the lie to be true are not, in fact, lies. [75]
The fourth of the five Buddhist precepts involves falsehood spoken or committed to by action. [76] Avoiding other forms of wrong speech are also considered part of this precept, consisting of malicious speech, harsh speech, and gossip. [77] [78] A breach of the precept is considered more serious if the falsehood is motivated by an ulterior motive [76] (rather than, for example, "a small white lie"). [79] The accompanying virtue is being honest and dependable, [80] [81] and involves honesty in work, truthfulness to others, loyalty to superiors, and gratitude to benefactors. [82] In Buddhist texts, this precept is considered most important next to the first precept, because a lying person is regarded to have no shame, and therefore capable of many wrongs. [83] Lying is not only to be avoided because it harms others, but also because it goes against the Buddhist ideal of finding the truth. [79] [84]
The fourth precept includes avoidance of lying and harmful speech. [85] Some modern Buddhist teachers such as Thich Nhat Hanh interpret this to include avoiding spreading false news and uncertain information. [83] Work that involves data manipulation, false advertising, or online scams can also be regarded as violations. [86] Anthropologist Barend Terwiel reports that among Thai Buddhists, the fourth precept also is seen to be broken when people insinuate, exaggerate, or speak abusively or deceitfully. [87]
In Gestaþáttr, one of the sections within the Eddaic poem Hávamál , Odin states that it is advisable, when dealing with "a false foe who lies", to tell lies also. [88]
Zoroaster teaches that there are two powers in the universe; Asha, which is truth, order, and that which is real, and Druj, which is "the Lie". Later on, the Lie became personified as Angra Mainyu, a figure similar to the Christian Devil, who was portrayed as the eternal opponent of Ahura Mazda (God).
Herodotus, in his mid-fifth-century BC account of Persian residents of the Pontus, reports that Persian youths, from their fifth year to their twentieth year, were instructed in three things – "to ride a horse, to draw a bow, and to speak the Truth". [89] He further notes that: [89] "The most disgraceful thing in the world [the Persians] think, is to tell a lie; the next worst, to owe a debt: because, among other reasons, the debtor is obliged to tell lies."
In Achaemenid Persia, the lie, drauga (in Avestan: druj ), is considered to be a cardinal sin and it was punishable by death in some extreme cases. Tablets discovered by archaeologists in the 1930s [90] at the site of Persepolis give us adequate evidence about the love and veneration for the culture of truth during the Achaemenian period. These tablets contain the names of ordinary Persians, mainly traders and warehouse-keepers. [91] According to Stanley Insler of Yale University, as many as 72 names of officials and petty clerks found on these tablets contain the word truth. [92] Thus, says Insler, we have Artapana, protector of truth, Artakama, lover of truth, Artamanah, truth-minded, Artafarnah, possessing splendour of truth, Artazusta, delighting in truth, Artastuna, pillar of truth, Artafrida, prospering the truth, and Artahunara, having nobility of truth.
It was Darius the Great who laid down the "ordinance of good regulations" during his reign. Darius' testimony about his constant battle against the Lie is found in the Behistun Inscription. He testifies: [93] "I was not a lie-follower, I was not a doer of wrong ... According to righteousness I conducted myself. Neither to the weak or to the powerful did I do wrong. The man who cooperated with my house, him I rewarded well; who so did injury, him I punished well."
He asks Ahuramazda, God, to protect the country from "a (hostile) army, from famine, from the Lie". [94]
Darius had his hands full dealing with large-scale rebellion which broke out throughout the empire. After fighting successfully with nine traitors in a year, Darius records his battles against them for posterity and tells us how it was the Lie that made them rebel against the empire. At the Behistun inscription, Darius says: "I smote them and took prisoner nine kings. One was Gaumata by name, a Magian; he lied; thus he said: I am Smerdis, the son of Cyrus ... One, Acina by name, an Elamite; he lied; thus he said: I am king in Elam ... One, Nidintu-Bel by name, a Babylonian; he lied; thus he said: I am Nebuchadnezzar, the son of Nabonidus. ... The Lie made them rebellious, so that these men deceived the people." [95] Then advice to his son Xerxes, who is to succeed him as the great king: "Thou who shalt be king hereafter, protect yourself vigorously from the Lie; the man who shall be a lie-follower, him do thou punish well, if thus thou shall think. May my country be secure!"[ citation needed ]
The Epimenides paradox reveals a problem with self-reference in logic. It is named after the Cretan philosopher Epimenides of Knossos who is credited with the original statement. A typical description of the problem is given in the book Gödel, Escher, Bach, by Douglas Hofstadter:
Epimenides was a Cretan who made the immortal statement: "All Cretans are liars."
A false dilemma, also referred to as false dichotomy or false binary, is an informal fallacy based on a premise that erroneously limits what options are available. The source of the fallacy lies not in an invalid form of inference but in a false premise. This premise has the form of a disjunctive claim: it asserts that one among a number of alternatives must be true. This disjunction is problematic because it oversimplifies the choice by excluding viable alternatives, presenting the viewer with only two absolute choices when, in fact, there could be many.
In philosophy and logic, the classical liar paradox or liar's paradox or antinomy of the liar is the statement of a liar that they are lying: for instance, declaring that "I am lying". If the liar is indeed lying, then the liar is telling the truth, which means the liar just lied. In "this sentence is a lie", the paradox is strengthened in order to make it amenable to more rigorous logical analysis. It is still generally called the "liar paradox" although abstraction is made precisely from the liar making the statement. Trying to assign to this statement, the strengthened liar, a classical binary truth value leads to a contradiction.
Bullshit is a common English expletive which may be shortened to the euphemism bull or the initialism B.S. In British English, "bollocks" is a comparable expletive. It is mostly a slang term and a profanity which means "nonsense", especially as a rebuke in response to communication or actions viewed as deceptive, misleading, disingenuous, unfair or false. As with many expletives, the term can be used as an interjection, or as many other parts of speech, and can carry a wide variety of meanings. A person who excels at communicating nonsense on a given subject is sometimes referred to as a "bullshit artist" instead of a "liar".
Deception is the act of convincing one or many recipients of untrue information. The person creating the deception knows it to be false while the receiver of the message has a tendency to believe it. It is often done for personal gain or advantage. Deception can involve dissimulation, propaganda and sleight of hand as well as distraction, camouflage or concealment. There is also self-deception. It can also be called, with varying subjective implications, beguilement, deceit, bluff, mystification, ruse, or subterfuge.
Honesty or truthfulness is a facet of moral character that connotes positive and virtuous attributes such as integrity, truthfulness, straightforwardness, along with the absence of lying, cheating, theft, etc. Honesty also involves being trustworthy, loyal, fair, and sincere.
Self-deception is a process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument. Self-deception involves convincing oneself of a truth so that one does not reveal any self-knowledge of the deception.
A microexpression is a facial expression that only lasts for a short moment. It is the innate result of a voluntary and an involuntary emotional response occurring simultaneously and conflicting with one another, and occurs when the amygdala responds appropriately to the stimuli that the individual experiences and the individual wishes to conceal this specific emotion. This results in the individual very briefly displaying their true emotions followed by a false emotional reaction.
Bad faith is a sustained form of deception which consists of entertaining or pretending to entertain one set of feelings while acting as if influenced by another. It is associated with hypocrisy, breach of contract, affectation, and lip service. It may involve intentional deceit of others, or self-deception.
Pathological lying, also known as pseudologia fantastica, is a chronic behavior characterized by the habitual or compulsive tendency to lie. It involves a pervasive pattern of intentionally making false statements with the aim to deceive others, sometimes for no clear or apparent reason, and even if the truth would be beneficial to the liar. People who engage in pathological lying often claim to be unaware of the motivations for their lies.
Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. It also may refer to questioning techniques used along with technology that record physiological functions to ascertain truth and falsehood in response. The latter is commonly used by law enforcement in the United States, but rarely in other countries because it is based on pseudoscience.
A half-truth is a deceptive statement that includes some element of truth. The statement might be partly true, the statement may be totally true, but only part of the whole truth, or it may use some deceptive element, such as improper punctuation, or double meaning, especially if the intent is to deceive, evade, blame or misrepresent the truth.
Interpersonal deception theory (IDT) is one of a number of theories that attempts to explain how individuals handle actual deception at the conscious or subconscious level while engaged in face-to-face communication. The theory was put forth by David Buller and Judee Burgoon in 1996 to explore this idea that deception is an engaging process between receiver and deceiver. IDT assumes that communication is not static; it is influenced by personal goals and the meaning of the interaction as it unfolds. IDT is no different from other forms of communication since all forms of communication are adaptive in nature. The sender's overt communications are affected by the overt and covert communications of the receiver, and vice versa. IDT explores the interrelation between the sender's communicative meaning and the receiver's thoughts and behavior in deceptive exchanges.
The Pinocchio paradox arises when Pinocchio says "My nose grows now" and is a version of the liar paradox. The liar paradox is defined in philosophy and logic as the statement "This sentence is false." Any attempts to assign a classical binary truth value to this statement lead to a contradiction, or paradox. This occurs because if the statement "This sentence is false" is true, then it is false; this would mean that it is technically true, but also that it is false, and so on without end. Although the Pinocchio paradox belongs to the liar paradox tradition, it is a special case because it has no semantic predicates, as for example "My sentence is false" does.
Othello error occurs when a suspicious observer discounts cues of truthfulness. Essentially the Othello error occurs, Paul Ekman states, "when the lie catcher fails to consider that a truthful person who is under stress may appear to be lying," their non-verbal signals expressing their worry at the possibility of being disbelieved. A lie-detector or polygraph may be deceived in the same way by misinterpreting nervous signals from a truthful person. The error is named after William Shakespeare's tragic play Othello; the dynamics between the two main characters, Othello and Desdemona, are a particularly well-known example of the error in practice.
Paternalistic deception is a type of deception that is ostensibly performed for the deceived individual's good by a person assuming a paternalistic role, whether they are their actual parent or not. The most used form of paternalistic deception are paternalist lies. They are told by an individual, a group, or an institution with the intent of benefitting the target lied to by sparing their feelings or preventing them from experiencing psychological harm. As they are justified by the assumption that they are in the target's best interest, they are a subset of prosocial lies. They can occur through omissions, half-truths, or white lies. Paternalistic lies can be manipulative, however their key feature involves the interference with the target's autonomy. This is induced by denying them access to accurate information and by limiting their behaviour choices. Confrontations with paternalistic lies can begin in early childhood and continue throughout an individual's life.
Child lying refers to children displaying varying degrees of deceptive behavior in a social situation. Children have been observed lying as early as age 2 and their deceptive skills increase sharply as they mature into adolescence. Children who have advanced cognitive skills for their age have an increased tendency to begin lying at earlier ages. Children may lie for various reasons including, but not limited to, escaping punishment for not obeying a task, through observation of their parents and peers, or lacking a comprehensive understanding of basic morality.
Truth-default theory (TDT) is a communication theory which predicts and explains the use of veracity and deception detection in humans. It was developed upon the discovery of the veracity effect - whereby the proportion of truths versus lies presented in a judgement study on deception will drive accuracy rates. This theory gets its name from its central idea which is the truth-default state. This idea suggests that people presume others to be honest because they either don't think of deception as a possibility during communicating or because there is insufficient evidence that they are being deceived. Emotions, arousal, strategic self-presentation, and cognitive effort are nonverbal behaviors that one might find in deception detection. Ultimately this theory predicts that speakers and listeners will default to use the truth to achieve their communicative goals. However, if the truth presents a problem, then deception will surface as a viable option for goal attainment.
In Jewish tradition, lying is generally forbidden but is required in certain exceptional cases, such as to save a life.
Motivation impairment effect (MIE) is a hypothesised behavioral effect relating to the communication of deception. The MIE posits that people who are highly motivated to deceive are less successful in their goal when their speech and mannerisms are observed by the intended audience. This is because their nonverbal cues, such as adaptor gestures, sweating, kinesic behaviors, verbal disfluencies, etc., tend to be more pronounced due to increased stress, cognitive load, and heightened emotional state. There is some disagreement regarding the MIE hypothesis, with a few nonverbal communication scholars arguing that deception should not be examined as separate for senders and receivers, but rather as an integral part of the overall process.
