The Undoing Project: A Friendship That Changed Our Minds
An interesting view into the lives of Daniel Kahneman and Amos Tversky. Lewis writes well, and the earlier parts of the book, describing the subjects' individual lives was compelling. Eventually I got a little bored reading about the path their partnership took; there was a clear trajectory established, and I didn't think there was much revelation as we continued.
Also, I mostly like reading the (popularized) science that these men produced. There was a little of that, but very little, so I was slightly let down.
