Introvert seems to be a nasty word these days. It's worth unpacking why, though, according to Susan Cain, author of Quiet: The Power of Introverts in a World That Can’t Stop Talking. In the book, she point to an overemphasis on the extrovert rooted in the shift from a 'culture of character' to a 'cult of personality,' stemming from the need to find new ways to quickly and repeatedly introduce one's self—to sell one's self—in the newly-urbanized United States in the early part of the 20th century.
Most leadership guides, hiring manuals and educational practices are grounded in the idea of supporting collaboration and motivating employees by having extroverts lead. The history of how this came to be is detailed in the revealing title by Susan Cain, Quiet: The Power of Introverts in a World That Can't Stop Talking.
