Introvert versus extrovert is one of the most debated personality questions of our time — and the answer has real implications for careers, relationships, and happiness.

Susan Cain's bestselling book Quiet argued that modern society is biased toward extroversion, undervaluing the extraordinary contributions of introverts. But extroverts would argue that social confidence and energy are genuinely advantageous. If you could choose your personality type, which would you pick?
