我们认为，大型选举可能表现出道德偏见（即，在选民内部偏好分布的条件下，选民认为道德上级的替代方案在大型选举中比在小型选举中更有可能获胜。这种偏见可能来自道德表达偏好，其中包括选民从他们认为道德的行为中获得的回报。在大型选举中，枢纽概率很小，因此表达偏好相对于物质私利变得更加重要。道德表达偏好可能对大型选举的结果产生不成比例的影响，原因有二。由于枢轴概率下降，道德表达的动机，使代理更有可能投票的基础上，道德的考虑，而不是在狭隘的自我利益的基础上，和一组代理谁选择投票越来越多地包括代理与大的道德表达的回报。我们提供的实验证据与道德偏见的假设是一致的。
We argue that large elections may exhibit a moral bias (i.e., conditional on the distribution of preferences within the electorate, alternatives understood by voters to be morally superior arc, more likely to win in large elections than in small ones). This bias can result from ethical expressive preferences, which include a payoff voters obtain from taking an action they believe to be ethical. In large elections, pivot probability is small, so expressive preferences become more important relative to material self-interest. Ethical expressive preferences can have a disproportionate impact on results in large elections for two reasons. As pivot probability declines, ethical expressive motivations make agents more likely to vote on the basis of ethical considerations than on the basis of narrow self-interest, and the set of agents who choose to vote increasingly consist of agents with large ethical expressive payoffs. We provide experimental evidence that is consistent with the hypothesis of moral bias.
