Stupidity is all around us. But in order to vanquish it, we must first understand it. In The Psychology of Stupidity, some of the world's leading psychologists and thinkers--including a Nobel Prize winner and bestselling authors--discuss in articles, essays and interviews

- why smart people sometimes believe in utter nonsense;

- how our lazy brains cause us to make the wrong decisions;

- why trying to debate fools is a trap;

- how media manipulation and Internet overstimulation make us dumber;

- why the stupidest people don't think they're stupid.
