It’s no secret that politicians can be driven by outsized egos. I mean, who among us really thinks he or she deserves a seat in Congress -- or a desk in the Oval Office?

But can egotism alone explain why so many elected officials seem to get caught telling lies, having affairs, committing financial improprieties or engaging in other scandalous behavior? Not everyone is convinced that it can, and some in the blogosphere have gone so far as to wonder if bad-boy (and bad girl) politicians are actually psychopaths. And a recent article in The Atlantic asks of these pundits:

Could they be right? If these pundits mean that the targeted office-seekers are evil or "crazy," probably not. But if they are pointing out that politicians and psychopaths share certain characteristics, they could be on to something.

Superficially charming, psychopaths tend to make a good first impression on others and often strike observers as remarkably normal. Yet they are self-centered, dishonest and undependable, and at times they engage in irresponsible behavior for no apparent reason other than the sheer fun of it... Psychopaths routinely offer excuses for their reckless and often outrageous actions, placing blame on others instead.

Yes, politicians are more likely than people in the general population to be sociopaths. I think you would find no expert in the field of sociopathy/psychopathy/antisocial personality disorder who would dispute this... That a small minority of human beings literally have no conscience was and is a bitter pill for our society to swallow -- but it does explain a great many things, shamelessly deceitful political behavior being one.
