Comparison is one of the most ubiquitous and versatile mechanisms in human information processing. Previous research demonstrates that one consequence of comparative thinking is increased judgmental efficiency: comparison allows for quicker judgments without a loss in accuracy. We hypothesised that a second potential consequence of comparative thinking is reduced judgmental uncertainty. We examined this possibility in three experiments using three different domains of judgment and three different measures of uncertainty. Results consistently demonstrate that procedurally priming participants to rely more heavily on comparative thinking during judgment induces them to feel more certain about their judgment.
比较是人类信息处理中最普遍和多用途的机制之一。先前的研究表明，比较思维的一个结果是提高判断效率：比较可以在不降低准确性的情况下更快地做出判断。我们假设，比较思维的另一个潜在结果是降低判断的不确定性。我们在三个实验中使用三种不同的判断领域和三种不同的不确定性测量方法来检验这种可能性。结果一致表明，在判断过程中程序性地引导参与者更多地依赖比较思维，会使他们对自己的判断更有信心。
