Effect of Voice Attractiveness and Group Identity in an Ultimatum Game

This study examined how voice attractiveness and group identity influence ultimatum decisions. Attractive voices only increased acceptance of 8:2 offers, suggesting a weak beauty premium effect. In-group proposers' unfair offers also had elevated acceptance, supporting Social Identity Theory.
