This is one of the best books I've ever read. Dunning sums up a career's worth of work in social psychology, and translates it into knowledge that we can all take away. The book is so worthwhile that I keep re-reading and referring to bits of it in my daily life.
If you thought you knew yourself, well - you're likely wrong!
I wish everyone who has a huge body of knowledge would do this for the rest of us. Thank you, Dr. Dunning!
