Note that there's some evidence that in some fields, experts are actually better outside their own field. This is discussed with relevant studies in Tetlock's "Expert Political Judgement." However, this is for predictions of the future, not judgments about correctness of basic models in their field.

That's interesting, because:

"In this age of academic hyperspecialization, there is no reason for supposing that contributors to top journals--distinguished political scientists, area study specialists, economists, and so on--are any better than journalists or attentive readers of the New York Times in "reading" emerging situations. The data reported in chapters 2, 3, and 4 underscore this point. The analytical skills undergirding academic acclaim conferred no advantage in forecasting and belief-updating exercises." (p. 233)

Sorry, bad phrasing on my part. Tetlock's work shows that experts are better outsider their own field compared to their own field, not necessarily compared to other people.

I suspect your phrasing is still bad, because I don't recall anything of the sort in the book.

I'm pretty sure that's what I meant to say. Unfortunately, I don't have my copy of the book off-hand. I'll have to get back to you.
