I'm still convinced I got a 4 on the European History AP exam in 1980 because I had a paragraph in my documents based essay saying "of course, some of the people probably PRACTICED witchcraft, whether it worked or not." Of coures, I might have missed more of the multiple choice questions than usual, though . . . .
I am quite certain the historiography of witchcraft was dealt a blow it hasn't recovered from when someone chose the metaphor "witchhunt" to describe 1950s purges in America. I have a friend who does a good bit of research on the witch trials in 17th century Germany; he says that the difference between received opinion IN THE FIELD and standard interpretation in the roomful of specialists at a conference is as wide as any of which he is aware -- that is to say that even the average member of the professional has as bad an understanding of the state of the research as Hill.
