I'm a fan of Michael Mauboussin's work, and so it's no surprise that I enjoyed his book Think Twice. The book is basically a summary of a lot of the cutting edge research into our decision-making biases and how we can improve on them.
The book draws on the research of a lot of books that are already profiled on this site, including those of Kahneman, Tversky, Cialdini etc. So in some ways I was already familiar with a lot of the topics Mauboussin covered and so it sometimes felt like I was watching a re-run. At the same time, however, it had been a while since I'd read a book on human biases, and considering I likely still make mistakes as a result of these biases, a refresher never hurts!
I recommend the book to anyone seeking to understand some common human biases, as recognition of these biases is the first step towards improving one's decision-making.
