报告内容提要

In a world in which facts are often difficult to verify and individual views are pervasive, how do people actually make use of the ‘wisdom of crowds’? We present decision-makers with a series of statements that are factually true or false, and evaluate how they utilize information about other individuals’ views, confidence levels, and higher order beliefs to make their own judgements. We find that people have difficulty in making effective use of more detailed information about others’ assessments, instead relying heavily on majority opinion as the main heuristic when forming their own judgements. In particular, valuable information about other individuals’ confidence levels regarding their views is underutilized, suggesting a straightforward opportunity for improving the decisions of individuals confronted with the wisdom of crowds.
