> If you decide to not sample further (that is find other chapters in the book of which you are an expert) then the conclusion that the book is trash is the only rational one. That's exactly the wrong kind of extrapolation I'm pointing out. If you found a flaw in one chapter, the book can be trash, and the chance of it being trash is definitely higher than without any other data, but whether the absolute chance of it being trash is sufficiently high enough can only be determined based on the nature of the flaw, and even then, the confidence for that conclusion can't be really that high.
