(No direct relevance to ME/CFS) James C. Coyne is an interesting renegade psychologist, as I've said before. He has written many critical posts about other psychological research. His latest blog post is: It is a small bit ranty, but does provide various links to more information. I'm not 100% one way on the issue itself. I do think Barbara Ehrenreich has made many interesting points before about the problems of "positive psychology". Also, that the social circumstances can make a big difference. At the same time, I do feel one can at least sometimes do things to see the positive or not the negative, and gratitude (mentioned briefly) can be something useful to nurture as appropriate. However, I found it interesting to revise some concepts such as: "discriminant validity" and "content validity". In particular, I found this idea interesting: This idea had occurred to me before, but never had a name for it. Generally I do find it interesting to read his stuff, to read about methods of critique of psychological research.
