I appreciated this book! Pinker is a little more technical here than I perceived him in "Enlightenment Now", the other book of his that I've read. I appreciated the detail, and would need to re-read this a few times to really retain it enough to use conversationally. That being said, while reading this you really are giving yourself time to refine how you think about the world, how your brain processes information it receives, and checking in on yourself and your ability to be honest with that information. It felt like a bit of a check-up from the neck-up.
