This book is about the different ways we (humans) make decisions. Most of the time, it is not a linear, logical process. We have biases, experiences, and are very susceptible to cues influencing us, such as the way something looks, what we were thinking about right before, and the fact that we have no innate grasp of what probability and statistics really are. Very interesting, but by no means a speedy read.
