Research on dual identity focuses mainly on how dual identifiers feel and behave, and on the reactions they elicit from others. In this article we test an unexplored aspect of dual identity: the dual identity group's potential to act as a possible gateway between the groups that represent the respective sources of the dual identity (e.g., Israeli Arabs as a gateway between Israelis and Palestinians). We predicted that to the extent that a group is perceived to have a dual identity, intergroup attitudes and behavior of the groups comprising that dual identity will be improved. This idea was tested across four studies. Study 1a and b were real-world correlational studies which revealed positive correlations between the perception of a dual identity and attitudes towards the outgroup. In Studies 2 and 3 we demonstrated experimentally that the mere presence of a group with a dual identity leads to improved outgroup orientations. In Study 4 we demonstrated how the manipulation of perceived dual identity can help improve attitudes towards the outgroup, and also provided initial indications regarding the mechanisms underlying the process at hand. We discuss the implications of the findings for the improvement of intergroup relations, and offer an outline for future research.
