While this is fascinating and I'm glad to have read it, it doesn't substantiate that this experiment set back psychiatry. The fact that the DSM-IV was prompted or encouraged by the experiment is suggested, but there's no argument for it. Even beyond that, the article doesn't even hint at an argument that the DSM-IV set back psychiatry (except offering the bare assertion that reductionism is false). Of course, the DSM…
Correct me if I'm wrong, but this is a review of a book that purports to make the case you're stating is not made here. That seems like a high bar for a review to me. Unless, do you mean you've read the book and the book fails to substantiate this claim?
Did the DSM-IV result in inaccurate diagnoses? Worse treatment? The review doesn't clearly state a single negative consequence. For that matter, reading the review, I can't even be sure if the book argues that the DSM-IV was bad, or if that's merely the review authors' opinion. I expect that kind of clarity from a review, and it's missing here.
Or again, on the point about the DSM-IV being a response to Rosenthal, what I'd like to read is something along the lines of "Cahalan's book presents detailed evidence that the DSM-IV was [influenced/prompted by/etc] the reaction to Rosenthal's experiment".
In defense of the reviewer: the worst issue might be a case where the title simply promises more than the article delivers. And the reviewer typically doesn't write their title, so it may be the editor who is to blame.
