Peers drag us up... and downLeonardo Bursztyn, an assistant professor at UCLA, and Robert Jensen a professor at the University of Pennsylvania, handed out fliers encouraging 11th-graders to sign up for a free SAT class. The twist: Some of the fliers said that everyone in the class would know who signed up. Some of the fliers said that decisions would be kept private. In honors classrooms, kids were 25 percent more likely to sign up if they knew their peers would be judging them. In non-honors classrooms, kids were 25 percent less likely to sign up.
