意见的多样性既带来问题，也提供机会。意见分歧可能会阻碍一个集团就采取何种决定达成一致意见。但与此同时，这些差异可能来自于获得不同的信息或运用不同的判断技能，这意味着它们为个人提供了改善自己意见的机会。本文探讨了前（聚合）的问题，假设个人利用这些机会的解决方案的影响。特别是，它认为，理性的个人修改意见意味着聚合问题是不稳定的，在一定意义上，解决他们利用嵌入在个人意见的信息有深远的影响的条件，我们应该对聚合程序。
ABSTRACT Diversity of opinion both presents problems and affords opportunities. Differences of opinion can stand in the way of reaching an agreement within a group on what decisions to take. But at the same time, the fact that the differences in question could derive from access to different information or from the exercise of different judgemental skills means that they present individuals with the opportunity to improve their own opinions. This paper explores the implications for solutions to the former (aggregation) problem of supposing that individuals exploit these opportunities. In particular, it argues that rational individual revision of opinion implies that aggregation problems are unstable in a certain sense and that solving them by exploiting the information embedded in individual opinion has profound implications for the conditions that we should impose on aggregation procedures.
