How to Know if Someone is Lying

The greatest liars who exist are those people who claim that they never lie. A recent survey conducted showed that an average human being in a week speaks about eleven lies on the lower side. So it is possible that there are those who speak up to about fifty untrue things in a single day. The Journal of Basic and Applied Social Psychology recently published an analysis that showed more than sixty percent of individuals lie at least once in a span of ten minutes while some told at least three lies during brief conversations.
