This is an excellent summary of several common errors that we are all prone to making in our thinking, especially when we are not on guard against them. The book reads smoothly, and the author offers numerous examples for each category of mistake he describes. It should be a text for the required courses on critical thinking that should be included in the curricula of every high school and college in the country, and indeed, in the world.
There is some overlap with the list of formal fallacies covered in a logic course, but this book also covers some areas that the logic texts do not. Together, they are better than either one alone, and it never harms to have more lights shining into our blind spots. This comprehensive approach helps us to better understand and avoid the pitfalls of our thinking, enabling us to make more informed and rational decisions.
