Partner selection for personality characteristics: A couple-centered approach

Both personality similarity and complementarity have been hypothesized to underlie mate selection. However, neither hypothesis has received strong and consistent empirical support. This study examined personality matching in couples by taking within-couple similarity as the basic unit of analysis. On the assumptions that individuals seek in another what they value in themselves but that they cannot always get what they want, it was hypothesized (a) that the similarity of partners' self-descriptions is positively related to self-liking, (b) that there is assortative mating for self-liking, (c) that there is significant similarity between subjects' ideal self-descriptions and their perceptions of their partners, and (d) that participants bias their perceptions of their partners in the direction of their self-conceptions. The authors examined and found support for the four hypotheses by analyzing California Q-set ratings provided by both partners of couples, who described themselves, their ideal selves and their partners.
