A book version of the class they teach at UC Berkley, this is more or less an overview of what we currently know about separating fact from fiction and making good decisions. It is primarily meant to serve as a guide to navigating a world full of information and parsing through all the noise to get at some truth. It relies heavily on several of the books you will be familiar with if you are interested in this field, and uses examples from modern scientific discoveries to illustrate different methods of thinking and investigation. There is a little at the end of the book about how to apply this to our world and how we could make better group decisions (think of our elections) with some different approaches. Again, there is no ground breaking information here, simply a summation of what has been found and how we might apply that to our daily lives. If you’re familiar with the field, a lot of it will be a review (which I didn’t mind, as remembering to combat my own biases always needs some prompting). It’s an excellent tool for those who want to stay informed, but don’t know who out there they can trust.
