Lie no relation functions
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. 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) 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.Consequences
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."
