Intellectual evolution of human is established by lying is social intelligence hypothesis. In 1976, Nicholas Humphrey who is psychologist brought forward this view in Social Skill Of Intelligence. Man's remote ancestors  are ensured their safety because they were a complex group compared to other primates. However, competition for food and mate became more fiercer. The more bigger a group is, the more complex lie is. Thanks to this process, intelligence of human is also developed. Self deception was favorable to survival and spread to an evolutionary process. Because of self deception, we became 'born liar.'
