We tend to assume that when something awful happens there must have been some great controlling intelligence behind it. It's understandable: how could things have gone so wrong, we think, if there wasn't an evil genius pulling the strings? The downside of this is that we tend to assume that if we can't immediately spot an evil genius, then we can all chill out a bit because everything will be fine.
But history suggests that's a mistake, and it's one that we make over and over again. Many of the worst man-made events that ever occurred were not the product of evil geniuses. Instead they were the product of a parade of idiots and lunatics, incoherently flailing their way through events, helped along the way by overconfident people who thought they could control them.
