Scientifically speaking, the more intelligent a species is the larger its neocortex (where higher-order brain functions take place) and its capacity for lying. Learning the complexities of lying is somewhat of a rite of passage from the time we are babies to our college years—fake cries, the art of concealment, bluffs, lies, flattery, cover-ups. Men tend to lie eight times more about themselves than to other people; women lie more to protect other people; extroverts lie more than introverts and married couples lie to each other in one out of every 10 interactions. Lying, in a sense, is a form of survival. This survivalist instinct carries over to your business interactions quite naturally.
