This book is very interactive with the reader and some parts are a little condescending. For example, in the Introduction, the author poses a question to the reader asking whether or not a personality description means the person in question is a farmer or a librarian. Rather than assuming that the multitude of readers may come up with different responses, the author states “Did it occur to you that there are more than 20 male farmers.”
While I understand where the author was going with the question, the author presumed that the readers would only answer one way and this recurs throughout the book. Another example in Chapter 16 assumed that the reader came up with the wrong answer and even stated that the most common answer to this question is wrong, however, the author does not explain how to come up with the correct answer.
All in all, a good part of the book is intriguing. The author clearly has conducted extensive research throughout his career and was able to present much of it in this book in a form that would be comprehensible to non-economics and non-psychology persons.
