Research participants who did an arithmetic brain-teaser and then reflected on their strategies for solving it went on to do 18% better in a second round than their peers who hadn’t set aside time to reflect, according to Giada Di Stefano of HEC Paris, Francesca Gino and Gary Pisano of Harvard Business School, and Bradley Staats of the University of North Carolina. The unconscious learning that happens when you tackle a challenging task can become more effective if you deliberately couple it with controlled, conscious attempts to learn by thinking, the research suggests.
