Susan Cain

Susan Cain is an American author, speaker, and co-founder of Quiet Revolution, whose debut book Quiet: The Power of Introverts in a World That Can't Stop Talking (2012) became a global phenomenon that is credited with reshaping cultural conversations about introversion, personality, and workplace dynamics. A former corporate lawyer who graduated from Princeton University and Harvard Law School, Cain drew on psychology, neuroscience, cultural history, and personal narrative to argue that Western society undervalues introversion and the qualities associated with it. Quiet spent more than eight years on the New York Times bestseller list, has been translated into more than forty languages, and won the Goodreads Choice Award for Nonfiction in 2012. Cain's 2012 TED Talk on introversion became one of the most-watched TED Talks of all time, with more than thirty million views. The book and the broader movement it inspired have influenced schools, corporations, and individuals around the world. Cain's subsequent books include Bittersweet: How Sorrow and Longing Make Us Whole (2022). She is a sought-after keynote speaker and her work continues to be widely influential in psychology, education, and organizational culture.
