虽然大量的社会选择理论文献讨论了将个人判断聚合为集体判断的问题，但关于群体交流中判断转换的正式工作要少得多。建立了一个判断变换模型，证明了一个基线不可能性定理：任何满足某些初始似是而非条件的判断变换函数都是同一性函数，在该函数下不会发生观点改变。我找出了摆脱这种不可能性的途径，并辩称，深思熟虑的Democat设想的那种群体沟通必须是“整体的”：它必须专注于相互关联的命题网络，而不是一次只关注一个命题，这呼应了迪昂-奎因关于科学理论测试的“整体论命题”。我的方法提供了不同可能的组通信进程所在的逻辑空间的映射。
While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is much less formal work on the transformation of judgments in group communication. I develop a model of judgment transformation and prove a baseline impossibility theorem: Any judgment transformation function satisfying some initially plausible conditions is the identity function, under which no opinion change occurs. I identify escape routes from this impossibility and argue that the kind of group communication envisaged by deliberative democats must be "holistic": It must focus on webs of connected propositions, not on one proposition at a time, which echoes the Duhem-Quine "holism thesis" on scientific theory testing. My approach provides a map of the logical space in which different possible group communication processes are located.
