Susan Horowitz Cain (born 1968) is an American writer and lecturer, and author of the 2012 non-fiction book Quiet: The Power of Introverts in a World That Can't Stop Talking, which argues that modern Western culture misunderstands and undervalues the traits and capabilities of introverted people. In 2015, Cain co-founded Quiet Revolution, a mission-based company with initiatives in the areas of children (parenting and education), lifestyle, and the workplace. Cain's 2016 follow-on book, Quiet Power: The Secret Strengths of Introverts, focused on introverted children and teens, the book also being directed to their educators and parents.
One out of every three people you meet is an introvert, and these people are overlooked in a culture that favors extroversion. Quiet points to the hidden and often-undervalued strengths that introverts possess.
