Although it is well known that appearance-based impressions affect labor market and election outcomes, little is known about the role appearance plays in financial transactions. We address this question using photographs of potential borrowers from a peer-to-peer lending site. Consistent with the trust-intensive nature of lending, we find that borrowers who appear more trustworthy have higher probabilities of having their loans funded. Moreover, borrowers who appear more trustworthy indeed have better credit scores and default less often. Overall, our findings suggest that impressions of trustworthiness matter in financial transactions as they predict investor, as well as borrower, behavior.
