Modesty can promote trust: Evidence from China

Lying to recommend unqualified friends: Diverging implications for interpersonal and epistemic trust inferences

When people are asked to recommend individuals they care about, they often grapple with conflicts regarding the level of honesty they should maintain when being truthful could potentially hinder those individuals' chances of receiving beneficial opportunities. In the current study, we examined how adolescents evaluate people based on how they respond to such dilemmas, with a focus on how it affects judgments of interpersonal and epistemic trustworthiness. We tested a sample of high school students in the southwestern United States (N = 78; Mage = 16.45 years), who were asked about a moral dilemma in which a story character needed to decide whether to recommend an unqualified friend. We experimentally manipulated whether the friend was very close to the standard (requiring a small exaggeration) or was far from the standard (requiring a large exaggeration) between participants. Across both exaggeration conditions, we observed a dissociation in judgments of epistemic and interpersonal trustworthiness: Lie-tellers were judged to be more interpersonally trustworthy than epistemically trustworthy, whereas truth-tellers were judged to be more epistemically trustworthy than interpersonally trustworthy. These results show that adolescents are capable of using information about an individual's lie-telling versus truth-telling decisions to make highly nuanced social inferences.

Trusting young children to help causes them to cheat less

Trust and honesty are essential for human interactions. Philosophers since antiquity have long posited that they are causally linked. Evidence shows that honesty elicits trust from others, but little is known about the reverse: does trust lead to honesty? Here we experimentally investigated whether trusting young children to help can cause them to become more honest (total N = 328 across five studies; 168 boys; mean age, 5.94 years; s.d., 0.28 years). We observed kindergarten children's cheating behaviour after they had been entrusted by an adult to help her with a task. Children who were trusted cheated less than children who were not trusted. Our study provides clear evidence for the causal effect of trust on honesty and contributes to understanding how social factors influence morality. This finding also points to the potential of using adult trust as an effective method to promote honesty in children.

First Impression Formation Based on Valenced Self-Disclosure in Social Media Profiles

This study aims to understand how the valence of self-disclosure (operationalized as the dominantly positive vs. balanced vs. dominantly negative social media posts of a future collaborator) influences first impression formation on social media. We also focus on trustworthiness as a mediator and perceived homophily as a moderator to specify the underlying mechanisms through which self-disclosure valence affects first impression formation. The results from an online experiment (N = 204) suggest that self-disclosure valence has a significant effect on perceived trustworthiness and likability when individuals evaluate an unknown future collaborator using the social media profile. Trustworthiness mediates the effect of self-disclosure valence on likability when the individuals feel that they are dissimilar or even slightly similar to strangers. At that time, individuals tend to seek cues from both self-disclosure valence and perceived homophily to form the trustworthiness perception, and the influence of self-disclosure depends on the level of perceived homophily.

Trait or testimony? Children's preferences for positive informants

Research indicates that children often show a positivity bias, or a tendency to favor positive information over negative information, in assessments of informant credibility in social and nonsocial situations. The current study investigated whether young children prioritize positive informant traits (i.e., nice vs. mean informant) as compared with positive speech content (i.e., positive vs. negative evaluation) in conflicting assessments of a work product. A total of 123 4- to 8-year-olds heard stories about a nice informant who gave a negative evaluation of a painting and a mean informant who gave a positive evaluation of the painting. Participants were asked who they would endorse, who they would ask about a future painting, and their friendship preferences. Children endorsed and asked the mean informant who provided positive testimony, but they chose to befriend the nice informant who provided negative testimony. Endorsements of positive testimony increased with age. Findings are considered in the context of the broader literature on selective social learning and trait understanding.
