To be honest, I don't think this book lived up to its title. "Vague writings on weird things people believe", or "Why these people are wrong" was the more common theme. Some interesting content, but very little of what I expected - ie social theory re: how 'weird things' catch on. There are three chapters entirely devoted to debunking weird things, which, again, is interesting, but not what I was expecting. Some fascinating footnotes, though.
