The role of epistemic and social characteristics in children’s selective trust: Three meta‐analyses

Over the last 15 years, researchers have been increasingly interested in understanding the nature and development of children's selective trust. Three meta-analyses were conducted on a total of 51 unique studies (88 experiments) to provide a quantitative overview of 3- to 6-year-old children's selective trust in an informant based on the informant's epistemic or social characteristics, and to examine the relation between age and children's selective trust decisions. The first and second meta-analyses found that children displayed medium-to-large pooled effects in favor of trusting the informant who was knowledgeable or the informant with positive social characteristics. Moderator analyses revealed that 4-year-olds were more likely to endorse knowledgeable informants than 3-year-olds. The third meta-analysis examined cases where two informants simultaneously differed in their epistemic and social characteristics. The results revealed that 3-year-old children did not selectively endorse informants who were more knowledgeable but had negative social characteristics over informants who were less knowledgeable but had positive social characteristics. However, 4- to 6-year-olds consistently prioritized epistemic cues over social characteristics when deciding who to trust. Together, these meta-analyses suggest that epistemic and social characteristics are both valuable to children when they evaluate the reliability of informants. Moreover, with age, children place greater value on epistemic characteristics when deciding whether to endorse an informant's testimony. Implications for the development of epistemic trust and the design of studies of children's selective trust are discussed.
