This book is great and so-so at the same time. Learning about human irrationality is one of my favorite topics, and I’ve read dozens of books in this realm. Many of these books have the same discussions and explain all of our various cognitive flaws, so they can get repetitive. When I started this book, I was pleasantly surprised that Pinker covered the same topics but added some newer examples of how these biases, heuristics, and other flaws show up in daily life. But eventually, I just got extremely bored with this book because it wasn’t much different than anything else I’ve read. I think the most surprising part about this book is how people either hate it because Pinker’s polarizing or call him a genius because of it. But since I’ve read so many of these books, there’s literally nothing new in here. I’m glad someone like Pinker wrote a book on rationality because he has such a large audience, but if you’re someone who reads these books, it’ll be extremely familiar from cover to cover.
