Let’s face it. Most of the readers this book is going to attract are going to be introverts. The author herself is an introvert. And I’m not saying that Cain is being biased. The book is well researched and points to many studies in the psychology of human personality. But the gist of the book is basically saying that we need to champion the introverted personality instead of discouraging it the way we have been doing for years. All throughout the book I was like “amen sister!”. But she’s preaching to the quire. The people that really need to read this book, the extroverts, are probably not going to read it in huge numbers.
