Well naive bayesianism, as practiced by the rationalists. Bayesianism itself can be reformed to get rid of most its problems, though I’ve yet to see a good solution for the absent-minded driver problem.

I read the article, not a single mention of things like the research on stereotype threat in chess. I wish rationalists would crack open a sociology book at some point in their lives. They’re so interested in social phenomena, but while Less Wrong has a tag for psychology (with 287 posts), history (245 posts), and economics (462 posts), they seem unwilling to look at sociology for explanations, with it not even having a tag on LW.
