We lie for all sorts of reasons. Sometimes we don't want to hurt people with the truth ("That dress is very slimming"), or we don't want to accept our own guilt ("I don't know who finished the cake"), or because it's a route of convenience out of an awkward scenario ("Yes, of course I'll be at your birthday party").
But what actually happens in our grey matter when we tell these fibs? And how does compulsive lying relate to bluffing your way to a poker victory?
The following infographic from Full Tilt Poker explores the psychology and known science of lying, from tracking a lier's eye movements to exploring the sections of our brain that are stimulated by telling porkies.
It won't turn you into the next Sherlock, but it might help you figure out which of your colleagues' has been eating your lunch.
