In the presence and absence of conflicting testimony, children’s selective trust in the in-group informant in moral judgment and knowledge access

Abstract

In this study, we assessed whether the trust model formed by children in a moral judgment context with an inaccurate in-group informant affected their corresponding trust model in the knowledge access context and whether conditions (the presence of conflicting testimony: an inaccurate in-group informant paired with an accurate out-group informant; the absence of conflicting testimony: only an inaccurate in-group informant) influenced the trust model. Children aged 3 to 6 years (N = 215; 108 girls) in blue T-shirts as in-group members completed selective trust tasks in the moral judgment and knowledge access contexts. Results for moral judgment showed that children under both conditions were more likely to trust informants based on accurate judgments and gave less consideration to group identity. Results for knowledge access showed that in the presence of conflicting testimony, 3- and 4-year-olds trusted the in-group informant at chance, but 5- and 6-year-olds trusted the accurate informant. In the absence of conflicting testimony, 3- and 4-year-olds agreed more with the inaccurate in-group informant, but 5- and 6-year-olds trusted the in-group informant at chance. The results indicated that older children considered the accuracy of the informant’s previous moral judgment for selective trust in the context of knowledge access while ignoring group identity, but that younger children were affected by in-group identity. The study found that 3- to 6-year-olds’ trust in inaccurate in-group informants was conditional and that their trust choices appeared to be experimentally conditioned, domain specific, and age differentiated.
