In-group favouritism is ubiquitous and previous studies have consistently found that individuals cooperate more with in-group members than out-group members in diverse contexts. Yet, there has not been much research on the role of the nature of groups in intergroup cooperation. A recent study found stronger levels of in-group favouritism amongst groups formed on the basis of shared moral values. However, it remained unclear whether the increased favouritism was caused by a greater tendency to act favourably towards the in-group or derogatorily towards the out-group. The present study thus investigated intergroup cooperation among morality-based and non-morality-based groups and examined the levels of cooperation with an in-group member and an out-group member as compared to a person whose group membership was unknown. Regardless of how groups were formed, in-group favouritism was present, while out-group derogation was absent. Furthermore, we found that the shared morality promoted in-group cooperation indirectly via low perceived out-group warmth. Our study provides further evidence that in-group favouring behaviour does not include derogating out-groups and points to the importance of further investigation into the role of the shared morality in intergroup cooperation.
