2) Liars will often talk a lot, about things completely unrelated to their lie, in an attempt to try and distract you/change the subject.
3) Over-emphasizes details. When people are trying to avoid telling the truth, they often pick some obscure point and talk about it a lot instead of focusing on the key issue.
4) Their shoulders will shrug ever so slightly. This is an indication that they are feeling anxious or unsure of themselves.
5) Answers questions not asked. Without even asking them a question, liars will defend themselves.
6) Dupers delight - some people will get so enthralled by telling the lie that they will often show this unintentionally, e.g. the corners of their mouths will turn up for a split second.
7) Listen for an echo. Liars will repeat your questions verbatim even though they clearly heard you the first time. As in “Are you lying to me?” “Am I lying to you?” You can end the conversation right there. You’ve got your answer.
8) Liars will often be so encapsulated by their lie and keeping their story straight that they will not be in control of the non-verbal cues, such as micro-expressions, that they are giving off. This is called a cognitive load.
9) A dishonest person is really careful with words. Listen for qualifying statements like, “As far as I remember”, and “if you really think about it”, or over-the-top denials.
10) Personal space is important to all of us, but liars like lots of it. If a person is slowly inching away from you or putting up physical barriers, like a purse or a glass, they may have something to hide.
