Overview
Susan Cain defines the central distinction between introversion and extroversion, explaining them as different temperamental styles that shape how people respond to stimulation and social interaction. She outlines the biological and early-development roots of temperament while noting cultural and situational influences. The founder lens is simple: keep the parts that improve judgment, simplify decisions, and make the next move easier to explain.
