Pros: There is research to support some of the author’s claims in this book about some sex differences between men and women like how there really are physiological differences between a typical male’s brain and a typical women’s brain. The book also points out that generally speaking men and women hear voices slightly differently, as well.
Cons: This book, for the most part, excludes people who are not cisgender male or cisgender female. Meaning that this book isn’t really about gender differences and why it matters, it is about why the binary genders matter in society. Although there is some research to support a lot of the writer’s claims, there is also a lot of bias opinions in this book.
The writer also tends to switch between the terms “gender” and “sex” which may lead some readers to misunderstand the HUGE contrast between the two. If you would like to learn more about psychology and gender differences please pick up an actual psychology textbook.
