Honesty-Humility, beliefs, and prosocial behaviour: A test on stockpiling during the COVID-19 pandemic
Emergencies such as the COVID-19 pandemic pose conflicts of interests between individual and societal welfare. One example is the run on many basic goods. However, such social dilemmas also afford the expression of personality traits associated with individual differences in prosocial behaviour. HEXACO Honesty-Humility, in particular, is associated with prosocial behaviour at a personal cost. Across two studies (N = 601), Honesty-Humility was positively associated with refraining from stockpiling in the past and intentions to do so in the future. Causal mediation analysis shows that this was not due to differences in beliefs that others would refrain from stockpiling. Instead, results suggest that faced with a social dilemma, individuals high in Honesty-Humility may have been willing to forego individual benefit. This provides rare evidence on the relationship between Honesty-Humility and prosocial behaviour in a field setting.
