More Money, More Problems? Can High Pay be Coercive and Repugnant?
研究机构审查委员会（IRB）可能认为高额激励具有强制性，一项针对医疗试验参与的MTurk情景实验发现，相当一部分被试也认同此观点，认为高额激励会导致更多后悔，且没有参与机会对更多人更好。
IRBs can disallow high incentives they deem coercive. A vignette study on MTurk concerning participation in medical trials shows that a substantial minority of subjects concurs. They think high incentives cause more regret, and that more people would be better off without the opportunity to participate. We model observers as judging the ethicality of incentives by partially using their own utility. The model predicts that payments are repugnant only to the extent that they affect the participation decision, and more so for larger transactions. Incentivizing poorer participants is more repugnant, and in-kind incentives are less repugnant than monetary incentives.
