"Rationality" is an interesting book that discusses how people think today. The author disproves some common beliefs about human nature and shows how we've cut down our thinking skills to the bare minimum and don't use the tools we've built up over thousands of years, like logic, critical thinking, probability, causal inference, and making decisions when we don't know what will happen. These tools have never been put together clearly and interestingly in our book, and they have never been a part of our curriculum.
