To Get Drivers to Put Down Their Phones, Make it a Game

If you’re trying to keep drivers from picking up their phones, make it a game, according to a new Proceedings of the National Academy of Sciences (PNAS) study led by researchers from the Perelman School of Medicine at the University of Pennsylvania. When drivers could earn points for making reductions in handheld phone use and had the chance to compete in a weekly leaderboard of others like them, researchers saw as much as a 28 percent reduction in handheld phone use while driving, a habit that stuck once the intervention—and the games—ended.
