Pepper & Nettle compellingly synthesize evidence indicating that temporal discounting is a functional, adaptive response to deprivation. In this commentary, we underscore the importance of the psychology of relative state, which is an index of relative competitive (dis)advantage. We then highlight two proximate emotional social comparison reactions linked with relative state – personal relative deprivation and envy – that may play an important role in the deprivation-discounting link.
