4/5 - Full review at emileereads: http://emileereads.com/blog/2017/2/16... 
 One third to one half of people in the world are introverts. Quiet is a wonderfully researched look into an introvert's mind and life in this extroverted society. Cain cited dozens of scientific studies and researched as many people and books in her quest to explain why quiet people are the way that they are, and how they can thrive in today's loud world. 
 A large section of the book focused on introversion in the work place. I was glad Cain talked at length about open office plans and how studies have proven they're not that effective. The thought of an open office makes me want to cry. I would literally walk out of an interview if it was an open office - after explaining why, of course. The book did a good job of explaining how important it is to use your quiet skills, even while presenting or working in groups. 
 At no point did Cain make this book into one glorifying the introverted person over the extroverted. She repeatedly emphasized the need for all types of people in order to create healthy environments and often compared the two. So often, I see memes or articles on the internet dissing extroverts for being loud and rude and I think that's a problem. I would happily read the extrovert version of this book. 
 I'm giving Quiet four out of five stars. I loved the content and the careful research - that part really could not have been better - but some parts read rather slowly.
