90% of Americans believe at least one conspiracy theory

But why? These are not people who want for education, and nor are those who follow their advice: the typical user of homeopathy is affluent and middle class. Why are kings, movie stars and the rich so susceptible to this snake oil?……..

Same reason they go into Scientology.

And I am going to have to argue about "these are not people who want for education". Being affluent middle class doesn't necessarily mean you are "educated". Actors and musicians may have degrees from Juilliard, which will make them educated, but that doesn't mean they are educated in science. Sports figures like Beckham, they are educated in playing soccer; Beckham signed with a team when he was 12; his football education may have been top notch, but I doubt his school education was Oxford level.
