This study indicates an interesting nuance in how to boost performance in teams. The study shows that if you recognize a top performer in a team, especially a high status person in the team, that the performance of the whole team improves. Note that this is still recognition, not compensation. And you still have to know how to distinguish the performance of individuals in a team, often no easy task. I still prefer the approach advocated in Great Work, a system where anyone can recognize anyone else who did something remarkable.
