Online interactions anchor on the creation and maintenance of individuals’ profiles. As a key component of individuals’ online profiles, digital profile photos are subject to artificial enhancements and may deviate from individuals’ actual physical appearances. The ubiquitous adoption of digital photo enhancement applications may influence how individuals behave in online interactions. In an online experiment, we study how individuals’ trust and trustworthiness may change after they can digitally enhance their profile photos. In the experiment, participants played the trust game (Berg et al. 1995) with their profile photos shown saliently on the game interface. While participants in the control group played the game normally, participants in the treatment group were asked to enhance their profile photos before playing the game. The results suggest that after digital photo enhancement, senders tend to reduce the amount sent (lower trust), while receivers tend to increase the amount returned (higher trustworthiness). There is significant gender heterogeneity in the impact of photo enhancement. Female senders are more likely to reduce trust, and male responders are more likely to increase trustworthiness. Digital photo enhancement of the opponents mitigates the main effects of the focal individuals. Based on the participants’ responses to the questionnaire, we find that trust propensity and risk attitudes are potential mechanisms for the main effect of digital photo enhancement.
