I am unsure why you say, "not backed by any kind of knowledge of the subjects" -- is it because his PhD is in Psychology and not Biology/Medicine? Do you believe that he can't have an opinion and share his n=1 research just because he isn't part of the AgriPharma Industrial Complex? He's very clear about his methodology and results -- this is exactly the type of transparent experimentation and learning that I come to this site to hear about.
