Umm I've been a forensic psychiatrist for years, and no one ever said to me "I got this idea from a book".
The comments on Edwards' Blog largely seem to imply that Campbell should have been polite considerate and respectful because Mr Ring had something to say. I call bullshit on that.
I make my living interviewing people; often unpleasant people, deluded people and a fair smattering of charlatans and liars. What Edwards doesn't appear to appreciate is the effect of knowing something (or quite a lot) about the interviewee and how that influences the interview style. Charlatans mostly piss people off, particularly if they are seen to be exploiting misery, and I think that John Campbell reacted honestly to that. I would far rather have that style of journalism in my living room than a simpering, polite ,all views are equal approach. Personally, I think John did a great job of the interview and the follow up with some real scientists. More required.
