An excellent book if you're delving into the power of being an introvert. Cain looks at the topic from many different angles without becoming psycho-babble or sounding like a blogger. The book is meticulously noted with sources cited. As a life-long introvert, it was fun and rewarding to see my personality style validated. As someone who works with youth, it puts "the quiet ones" in a whole new light and suggests that I should rethink how those kids are to interact with the larger group. Recommended for managers and leaders.

Great book. This should be required reading for educators and people in management.

I expected more science and less supposition and anecdote and small studies used to justify sweeping conclusions. And some parts I found ridiculous. But, there were certainly some interesting points that help to frame feelings and behaviors for non-party animals. So, definitely a book with some value, read carefully with large grains of salt. Personally I don’t think there’s anyone out there who has truly nailed all of the various aspects that make us who we are, and I don’t believe it’s possible.

Generally very interesting. Gives clear understanding of introversion and its powers/abilities. But with many 'popular science' books, it at times makes leaps that can't be justified and seems a bit far-fetched. And it order to be relatable with an American audience, it feels the need to use religious examples at times and have a chapter on religious introverts, which seems inappropriate. That being said, it is still worth a read to better understand the introvert/extrovert forces in society and better understand introverts.

Empieza muy bien e interesante, con las bases fisiológicas y sociales de la introversión, pero luego empieza a divagar en casos concretos y anécdotas que hicieron que la lectura resultara aburrida. Conseguí leerme tres cuartas partes del libro... con esfuerzo.

A great book for MBTI nerds like me, but also an important book for anyone who manages other people or has a close relationship with an introvert. I could talk about this all day long, but in sum, I think I'll be referencing this frequently at home and at work.

I was a little disappointed by this book. It is about introverts. I felt as though the book was having a hard time finding a lane. It started with how to identify if you are an introvert, jumped over to Cain's personal experience, talked about the history of introverts, research on the personality type, famous introverts, how to work with introverts, if your partner is an introvert, different cultures (specifically Asian), and then if your kid is one. I applaud Cain's desire to take on many sides of the personality trait, however, I wish there was one book for each specific topic instead of one broad stroke. Although I found the material interesting, it is a very abstract concept and I felt like their definition saw the world in black and white (introverts vs. extroverts) but it is more complicated than that. It probably comes down to different expectations. I went into the book thinking it was a guidebook for how to work with introverts or be one in an extroverted society and it felt as though Cain was trying to prove that introverts exist in the first place.
