Abstract: Mate copying (MC) refers to the increased probability of preferring an individual as a mate, as a result of them having been chosen by same-sex peers previously. How changes in the world, such as the increased use of social networking sites, affect MC has not received much attention. Participants were shown photographs of opposite-sex target individuals, and told that the profiles had a high, moderate, or low number of opposite-sex Facebook friends. A two-way analysis of variance (ANOVA) indicated that opposite-sex profiles were considered the most desirable when no information was given about thegender distribution of their Facebook friends. Both men and women found opposite-sex profiles to be least desirable when they had a high number of opposite-sex friends. The findings contribute to the literature by providing further information about the mate selection processes for both sexes, and how social networking sites have changed the way interpersonal relationships are formed.
