A while ago I watched a BBC documentary called "The Syphilis Enigma" narrated by paleopathologist Charlotte Roberts. The gist of the program was to prove that syphilis existed in the Pre-Colombian Old World. Then I read this article about "research by documentary" where scientific theories are published without any peer-review. Changed my mind. Darn.
