Are you a sports “superfan”? Or do you wonder what’s driving the superfans in your life? Daniel Wann, PhD, of Murray State University, talks about why being a fan is usually good for people’s mental health, how they choose the teams they root for, why some are fair-weather fans while others love to cheer for the underdog, how fandom is changing among younger people, and whether a crowd of supportive fans can affect the outcome of a game.
