When Does Competence Matter? Character as a Moderator in the Development of Trust

This article examines the relationship between the two fundamental attributes of the trustee: character and competence. Although the trust research predominantly adopts an additive perspective, our research emphasizes a moderation (i.e., multiplicative) relationship and the significance of their interaction. We find that competence is an important but not always reliable predictor of trust. First, the positive effect of competence is conditional on the trustee's high character. Second, higher competence can have a lower marginal effect as character decreases. Furthermore, situational assurance weakens the effect of character on competence, which explains the additive joint effect found in previous research. Our modified trust game also makes a methodological contribution by examining the interaction between the various personal and situational sources of trust (as compared with the lone operationalization of character in the classic trust game). We discuss the shortcomings of the additive perspective and the implications of our method and findings.

Susceptibility to Being Lured Away by a Stranger: A Real-World Field Test of Selective Trust in Early Childhood

In this preregistered field study, we examined preschool children's selective trust in a real-life situation. We investigated whether 3- to 6-year-old children (total N = 240) could be lured to a new location within their school grounds by an unfamiliar adult confederate. In a between-subjects manipulation, the confederate established either a high or a low level of personal credibility by providing information that the child knew to be either true or false. In Experiment 1, in which the confederate was female, children showed sensitivity to informational accuracy by being less willing to leave with an uninformed confederate, and this effect increased with age. In Experiment 2, in which the confederate was male, children were reluctant to leave regardless of informational accuracy. These findings point to real-world implications of epistemic-trust research and provide the first evidence regarding the early development of selective trust in a high-stakes naturalistic context.
