Does Leader Same-sex Sexual Orientation Matter to Leadership Effectiveness? A Four-study Model-testing Investigation.

Despite the legalization of same-sex marriage in the United States (U.S.) and an increasing number of out gay and lesbian business leaders, we have little knowledge of the role played by leaders' same-sex sexual orientation in the leadership process. To fill this important research void, we drew from a recent theoretical model on leaders' sexual orientation and conducted four experimental studies designed to test and retest leaders' same-sex sexual orientation affects followers' leadership perceptions and conformity to influence attempts, and the intersectionality of leaders' same-sex sexual orientation with leaders' gender orientation and follower characteristics may modify the influences of leaders' same-sex sexual orientation on the follower outcomes. Based on over 2,100 working adults in the U.S., the results of the four studies, where leaders were depicted as charismatic, indicate that leaders' same-sex sexual orientation could have negative impacts on the follower outcomes. However, same-sex sexual orientation leaders did not suffer double stigma penalization by having additional marginalized identities (e.g., also being women). Female followers were more supportive of same-sex sexual orientation leaders than male followers. Our research advances knowledge of and responds to calls for more research attention to leader sexual orientation in the leadership process. Research and practical implications and directions for future research are discussed.
