"So what are we to make of people's need to believe in conspiracy theories such as the one floated above? In his famous essay on conspiracy theories in America, the historian Richard Hofstadter noted that a significant part of these tales is psychological projection – people ascribe their own worst traits to the imagined enemy, thus relieving themselves of various kinds of responsibility. And so with an increasingly savvy reality TV audience, who understand that Cowell always wins, yet watch in ever greater numbers and have to find a way of elevating their involvement into something more than a mug's game. Both fans and haters need to develop outlandish conspiracy theories because they can't actually believe millions upon millions are genuinely in thrall to this stuff."
