内容简介:

Online social interactions hinge on creating and maintaining individuals’ virtual profiles. As a critical component of virtual profiles, digital photos are subject to artificial enhancements and may deviate from individuals’ actual physical appearances. The ubiquitous adoption of AI-powered digital photo enhancement applications may influence how individuals behave in online interactions. In an online controlled experiment, this paper studies how individuals’ trust and trustworthiness change after digitally enhancing their profile photos. Participants played the trust game (Berg et al. 1995) with players’ profile photos shown saliently on the game interface. Participants in the treatment group enhanced their profile photos and used enhanced profile photos during the game. Experiment results suggest that senders in the treatment group reduce the amount sent (exhibit lower trust), while receivers in the treatment group increase the amount returned (show higher trustworthiness). Additional analysis reveals significant gender heterogeneity in the impact of photo enhancement. Female senders reduce trust more than male senders, and male responders increase trustworthiness more. Further, photo enhancement by the opponents mitigates the main effects. Analyzing participants’ responses to the post-experiment questionnaire, we find the treatment effect of photo enhancement could be attributed to changes in trust propensity and risk attitudes.
