Making Behavior Change Stick
The Behavior Change for Good Initiative unites a world-class, interdisciplinary team of academic experts with leading organizational partners to help advance the science and practice of behavior change. Our pioneering “megastudy” approach allows us to simultaneously test dozens of ideas for changing a behavior, proposed by a diverse array of scientists, to identify which strategies work best and for whom, and how to most effectively create enduring behavior change to transform people’s lives for the better.
