White lies keep social dignity intact and are far more prevalent than most people realize. Several studies have found that an average person is lied to from 10 to 200 times a day - mostly just to keep a conversation going, to avoid conflict, or to establish a connection with someone.

We lie more to strangers than we lie to co-workers. Extroverts lie more than introverts. Men lie eight times more about themselves than they do other people. Women lie more to protect other people.

While it can feel unfair to have to make a career decision because of a morally deficient boss, doing so can sometimes lead you in the right direction, if a bit faster than you otherwise would have preferred.

A good lie detector doesn't jump to conclusions but tries to understand the person across the table, her personality, and her motivations. Your goal as a lie spotter isn't to point the finger and say, 'You're lying' - your goal is to get to the truth.
