On the surface, this was about the same topic as Thinking, Fast and Slow by Daniel Kahneman - the two ways our brain processes information. But this was considerably better. The Kahneman book presented the unconscious brain, responsible for fast thought and (often incorrect) instinctual responses and biases as pretty uniformly bad. This book acknowledged that the unconscious brain or "hidden" brain often makes incorrect decisions, but acknowledged that we cannot stop that from happening. We can be aware of it, but it's largely evolutionary thinking that has thousands upon thousands of years of natural selection behind it. Just as in his really interesting podcast, Vedantam presents anecdotes to describe the differing ways our hidden brain affects our thinking and responses, ranging from simple things to serious issues like race bias. It was definitely eye-opening and interesting.
