In our society, which prefers and glamorizes extroverts, the natural born leaders, and the charismatic public speakers, introverts are, at times, looked upon as second-class citizens. Quiet gives validation and appreciation to this personality type by telling us why introverts are important to our work places, work teams, and society. The book provides a personality test to determine if one is an extrovert or introvert, which is not always a clear cut divide. Quiet cites scientific studies of introversion and gives examples of their positive presence among us, and those who have made a difference in the world like Rosa Parks and Ghandi. Cain also suggests life coping strategies for those introverts who find themselves living in the role of an extrovert. Quiet is a great read for everyone interested in the human psyche, human behavior and the world of introverts, as well as for those who love them or work with them.
