If I were Seth Roberts, I would look into my blog archive for the initial anecdotal results I posted on experiments now proven to have negative results. If most of these posts seemed positive, I probably have confirmation bias.
I don’t think that can be done, since I don’t know of any of his theories which have been ‘now proven to have negative results’. I think a post linked somewhere here accuses Roberts of actively avoiding clinical trials, where Roberts replies that he worked with a SUNY professor on 20 case-studies for the Shangri-La diet. Since the diet is his centerpiece and the subject of his only book (AFAIK), it probably represents the best-case testing of any of his theories...
How would you test yourself for confirmation bias?
