Why is Taubes so interested in bias? For several decades, it has been the conventional wisdom that dietary fat (and especially saturated fat) contributes to obesity, heart disease, and cancer. Judging from Taubes’ exhaustive research -- indeed, I'd be surprised if any other book examined bias within a particular scientific field in such detail -- the conventional wisdom was based on unreliable and slender evidence that, once established and institutionalized in government funding, set a pattern of confirmation bias by which further research was judged (or ignored).
I recommend that you read the article and read the interviews at the bottom. If there's this much bias just for diets, it makes you wonder about the global warming debate.
