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 is very controversial, and many people could fill in the argument, but this article doesn't do it.
