While your chances of living to (briefly) regret showering in some rundown motel as your lifeblood washes down the drain in glorious black-and-white are somewhat less than probable, the odds that you've encountered an honest-to-goodness psycho in your day-to-day activities are pretty much a sure shot. In fact, he might be the d******e who made you work that extra shift last Saturday.
When we say that psychopaths walk undetected among us, that's because not even experts know how to spot them -- it's not like they're always whistling down the sidewalk with a cloak of human skin draped over their shoulder. The gold standard exam for psychopathy literally requires the testee to be imprisoned, and the next-best test is a long questionnaire that requires a trained professional to properly score. As such, science's best guess places the number of psychopaths in the general population at around one in a hundred.
One in 10 if you live here.
That means that if you live in an average-sized city, you probably bumped into a couple psychopaths the last time you ran out for tacos. Where the numbers get really crazy, though, is when you examine people in certain careers -- that is, middle-management and above -- because that's when the number suddenly quadruples. It seems that those with psychopathic tendencies are genetically pre-wired to become other people's bosses.
