Lie
A lie is an assertion that is believed to be false, typically used with the purpose of deceiving or misleading someone. 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. 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.
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).
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."
The question of whether lies can be detected reliably through nonverbal behavior 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. 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.
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.
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. 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.
