Even the reputable books tend to resort to anecdotal evidence and do not evaluate any of their claims. I'd go crazy if I had to read 100 of them but the ones I read were based on 100% survivorship bias and 0% scientific studies.

Personally, it seems to me that general business books --- that is, the ones that aren't textbooks (accounting, microeconomics, etc.) --- are merely a sub-genre of the self-help category and that these books may provide value by giving some motivation and inspiration at best and, at worst, provide huge disvalue by misinforming.
