What Behavioral Science Says About Changing Habits Around the New Year
Episode Description
EPISODE OVERVIEW Wharton professor Katy Milkman explains the “fresh start effect,” a behavioral science finding showing that moments like New Year’s Day, Mondays, and major life changes increase motivation to pursue long-term goals. She discusses why this motivation fades, how present bias affects decisions, and why tools like automation, defaults, and planning are more effective than willpower alone. She also talks about how organizations can use timing to encourage positive behavior change and how AI may support goal follow-through.
