Quiet shows the slow rise of the extrovert ideal for success throughout the 20th century, while making a case for the underappreciated power of introverts and showing up new ways for both forces to cooperate.

Susan Cain has a top TED talk about the power of introverts which has been viewed over 10 million times.

The reason is that her book and talk made a lot of people feel heard for the first time.

In the seven years of research leading up to the publication of Quiet in 2012, Cain uncovered the slow rise of the extrovert ideal in the public and American workplace.

This helped her understand where a lot of her personal struggles as a Harvard Law School graduate and Wall Street lawyer came from, and why she could never have thrived in these environments.

Her book is a well of wisdom about personality types, workplace relationships and human interaction.
