Does this book review in The New York Times make any sense to you?
How can what these two did (as explained in the review) be called "research"? It sounds more like a hodgepodge of their personal opinions and experiences, wrapped up in psycho mumbo jumbo.
What this review (and other observations) demonstrates to me is that thought processes in the US are overwhelmingly influenced by the "research" of Israeli professors. And I don't think this is a good thing. We need diversity in our thought processes, and they and their ilk are preventing us from having it.
