It’s hard to say anything about this book that has not already been said. Yes, there are offensive bits there, no matter who you are. Definitely too many places where “he” is used as a neutral pronoun.
But all all of this fades as I enjoyed the author’s unique taste – the truth. The drive to find out the hidden truth, the true causality, trying to eliminate any alternative hypothesis – it’s so much fun.
The Q&A ask what’s left on the editing room floor. The authors respond that few things are left on the editing room floor, but a lot is left on the research floor. If they can’t find a story backed up by data, they just don’t publish it. I believe it.
