We study the interaction of different motives and decision processes in determining behavior in the ultimatum game. We rely on an experimental manipulation called ego depletion which consumes self-control resources, thereby enhancing the influence of default reactions or, in psychological terms, automatic processes. We find that proposers make lower offers under ego depletion, i.e. self-centered monetary concerns are the default mode and not other-regarding considerations (fairness towards others). Responders are more likely to reject low offers under ego depletion, i.e. the affect-influenced reaction to reject unfair offers (reaction to unfairness towards oneself) is more automatic than unconditional monetary concerns.
