1．Studies show that you may be lied to every day anywhere from 10 to 200 times．We say，"Nice song．""Honey，you don't look fat in that，no．"But another study showed that strangers lied three times within the first 10 minutes of meeting each other．We lie more to strangers than we lie to coworkers．Men lie eight times more about themselves than they do other people．Women lie more to protect other people．If you're married，you're going to lie to your wife/husband in one out of every 10 communications．If you're unmarried，that number drops to three．But look，if at some point you got lied to，it's because you agreed to get lied to．Truth about lying：lying's a cooperative act．Not all lies are harmful．Sometimes we're willing to lie for the sake of social dignity （尊严），maybe to keep a private secret．
Lying is complex．It's woven into the fabric of our daily and business lives．We're deeply disturbed by the truth．We explain it，sometimes for very good reasons，other times just because we don't understand the gaps between ideals and realities in our lives．We're against lying，but secretly we're for it in ways that our society has practiced for centuries and centuries．It's as old as breathing．It's part of our culture and history．Think the stories from Dante，Shakespeare，the Bible，News of the World．
Lying has great value to the evolution of human being．Researchers have long known that the more intelligent the species，the more likely it is to lie．We human like to become leaders．It starts really early．How early？Well，babies will pretend to cry，pause，wait to see who's coming and then go right back to crying．One-year-olds learn hiding truth．Two-year-olds bluff （虚张声势）．Five-year-olds lie outright and try to control via flattery （讨好）．Nine-year-olds，masters of covering up．By the time you enter college，you're going to lie to your mom in one out of every five interactions．By the time we enter this work world to be breadwinners，we've entered a world that is just full of fake digital friends，business media，identity thieves，world-class cheats，--in short，a post-truth society．
What do you do？Well there are steps we can take to guide our way through the bushes．Trained lie spotters get to the truth 90% of the time．The rest of us，we're only 54% accurate．Why is it so easy to learn？There are clever liars and stupid liars．There're no real original liars．We all make the same mistakes．We all use the same techniques．
