Dan Heath will talk about the new book he’s co-authored, Switch: How to Change Things When Change Is Hard.  Bringing together decades of counterintuitive research in psychology, sociology, and other fields to shed new light on how we can effect transformative change, Switch shows that successful change follows a pattern, a pattern you can use to make changes that matter, whether it’s in changing the world or changing your waistline.  The presentation will be followed by a book signing and reception.  Free and open to the public.  RSVP to www.caseatduke.org/events
