New research finds that narcissism is on the rise among college students. The study suggests that too much self-esteem building in elementary school may be a root cause. It also points the finger at permissive parenting, and an increasingly materialistic and celebrity-obsessed culture. Larry Mantle talks with the study's lead author, Jean Twenge, Associate Professor of Psychology at San Diego State University and author of the book Generation Me: Why Today's Young Americans are Confident, Assertive, Entitled - And More Miserable than Ever Before (Free Press).
