Learning from multiple informants: Children's response to epistemic bases for consensus judgments.

Consensus has both social and epistemic value. Children conform to consensus judgments in ways that suggest they are sensitive to the social value of consensus. Here we report two experiments providing evidence that 4-year-old children also are sensitive to the epistemic value of consensus. When multiple informants gave the same judgment concerning the hidden contents of a container, based on the observation of one of their members, children's own judgments tended to align with the consensus judgment over the judgment of a lone character, whose observation received no endorsements. This tendency was reduced, however, when children were shown that the group consensus lacked epistemic warrant. Together, the findings provide evidence that young children are sensitive to the epistemic basis of consensus reports.
