The constellation of co-adapted traits that facilitate short-term mating promote the use of riskier and interpersonally antagonistic intrasexual competition tactics. Aggressive behavior can be used to vie against rivals for mates and resources that facilitate reproductive success; however, there is limited research regarding whether individual differences in a short-term mating orientation (i.e., unrestricted sociosexuality) are reliably associated with same-sex aggression, particularly indirect aggression. There is also some research suggesting that short-term mating tendencies are linked to inter-individual variability in the desire to compete with same-sex others for access to mates and reproductive resources (i.e., intrasexual competitiveness). We therefore speculated that intrasexual competitiveness might help to explain why those pursuing a short-term mating strategy may perpetrate more indirect aggression toward same-sex peers. In a sample of 290 Canadian heterosexual young adults, unrestricted sociosexuality positively predicted same-sex indirect aggression and intrasexual competitiveness, and intrasexual competitiveness mediated the positive link between unrestricted sociosexuality and indirect aggression. Exploratory analyses revealed that the desire facet of sociosexuality was driving the effect. These findings suggest that those with a short-term mating orientation, particularly those with unrestricted sociosexual desires, engage in more indirect aggression against same-sex peers, and that this association is, in part, explained by an inclination to be combative with same-sex rivals over social and mating resources.
