Superordinate and subgroup social dilemmas: Self-interest and group identity motives
Annual Convention of the American Psychological Society
This study examined how self-interest and group-identification motives affect responses to superordinate (everyone belongs to one group) and subgroup (involving two groups) social dilemmas. Although both of these factors significantly predicted giving in each condition, cooperation was greater in the superordinate condition and this relationship was mediated by measured group identity.
