Preschoolers Continually Adjust Their Epistemic Trust Based on an Informant's Ongoing Accuracy.

Children aged 4-7 years (N = 120) played four rounds of a find-the-sticker game. For each round, an informant looked into two cups and made a claim about which cup held a sticker. At the end of each round, children guessed the sticker's location, and then the sticker's actual location was revealed. For three of the rounds, the informant accurately reported the sticker's location. But critically, for one round-either Round 1, 2, or 3-she was inaccurate. Children continually adjusted their trust in the informant as they obtained more information about her accuracy. Relations between the informant's pattern of accuracy and children's trust were robust, neither mediated nor moderated by children inferences about her intent or traits.
