I just finished my first one - "Why We Sleep". I thought it was very good - informative but accessible. Not a ton of self-help drivel. The action item from it is mostly just to be cognizant of your sleep schedule and don't take it for granted.
My next book was going to be Thinking Fast and Slow.
However, before I started my next book, I revisited that thread to see what else I should read. Lo and behold - both these books received lots of criticism that I was unaware. Replication problems and manipulated data. The tide had turned and these books were now spurned.
What are some similar books (not entirely dumbed down pop psychology I guess) that hold up to scrutiny? Are there any? Or is book bound to have errors that some people will criticize them for?
