Nudging the nudger: Performance feedback and organ donor registrations
通过一项涉及近700名客服代表的随机对照试验，研究发现向客服代表提供重复绩效反馈（无论是否包含同行比较）能使其每日器官捐赠登记量增加25%，且对高、低绩效者均有提升效果。
In a randomized controlled trial conducted in three waves over 2.5 years and involving nearly 700 customer-service representatives (CSRs) from a Canadian government service agency, we studied how providing CSRs with repeated performance feedback, with or without peer comparison, affected their subsequent organ donor registration rates. The feedback resulted in a 25 % increase in daily signups compared to otherwise equivalent encouragements and reminders. Adding benchmark information about peer performance did not amplify or diminish this effect. We observed increased registration rates for both high and low performers. A post-intervention survey indicates that CSRs in all conditions found the information included in the treatments helpful and motivating, and that signing up organ donors makes their job more meaningful. We also found suggestive evidence that performance feedback with benchmark information was the most motivating and created the least pressure to perform.
