In this episode of Moving Digital Health, host Reuben Hall speaks with Dr. Daniel Lieberman, professor of biological sciences and former chair of the Department of Human Evolutionary Biology at Harvard. Dr. Lieberman makes the case that one of the most powerful design levers for getting people to move is social connection. He walks through why Peloton works despite being a screen in a basement, why Strava motivates one type of user and alienates another, and what his team learned building the Crimson ZIP app with us at MindSea to get Harvard students moving.
