In order to extend the literature on consensual nonmonogamy, we conducted two studies that examined public awareness and perceptions of polyamory. Specifically, we identified individual differences that predict people's attitudes towards polyamory and also explored whether manipulations grounded in prejudice-reduction theory might lead to more positive perceptions. In both studies, individuals reporting more traditional traits (e.g. political conservatism and religiosity) had more negative attitudes towards polyamory. In addition, participants' prior exposure to polyamory (i.e. familiarity with the term polyamory or knowing someone polyamorous) was positively related to attitudes towards polyamory, consistent with Allport's contact hypothesis. Finally, an experimental manipulation revealed that participants who either received additional information about polyamory (consistent with the notion that increased knowledge about outgroups can reduce prejudice; Pettigrew & Tropp) or were asked to consider the advantages and limitations of monogamy (consistent with value selfconfrontation theory; Rokeach) exhibited more positive attitudes towards polyamory than did participants who only received a standard definition of polyamory. As our results represent some of the first empirical findings on perceptions of polyamory, implications for addressing the stigmatisation of this relationship style are discussed.
