| Abstract: | Although the existence of the false consensus effect is beyond all doubt, its interpretation as a judgemental bias is still a matter of debate. Krueger recently proposed a new measure for this phenomenon, called the truly false consensus effect (TFCE). This measure consists of correlating the subject's endorsement of each item with the error he or she made in estimating the popularity of that same item. I question the validity of this measure, arguing that it could be negative even in cases where false consensus is at work. I present an inter‐group study where participants made percentage estimates for various behaviours. The results yielded a significantly negative TFCE, although other measures of false consensus demonstrate that the phenomenon is present. I discuss the differences between Krueger's studies and my own, and suggest that a better measure of false consensus might be the particle correlation between endorsement and estimated popularity, controlling for true popularity.
