1Chapter 17 Human Mate Choice and ParentingThe Psychology of Human Mate PreferencesEvolutionary theory generates some testable predictions about the psychology of human mate preferencesoFor much of evolutionary history humans have lived in foraging societiesoThe adaptive challenges that men and women face in these kinds of societies are likely to have shaped their mating strategiesoFor women this might have meant choosing men who would provide them with access to resourcesoIt might be important for women to choose a mate who will be a good provideroMens reproductive success depends largely on the fertility of their partners so it is plausible that selection favoured men who focused on this attributeoWomens fertility is highest when they are in their 20s and declines to zero when women reach menopauseoThus selection should have favoured men who chose young and healthy matesoFor both genders it is important to find mates that they can get along withIf evolution has shaped the psychology of human mating strategies then we would expect to find common patterns across societiesPeople generally care most about the personal qualities of their matesoMen and women around the world rate mutual attraction or love above all other traitsoThe next most highly desirable traits for both are personal attributes such as dependability emotional stability and maturity and a pleasing dispositionoInteresting and surprising that neither sex seems to value chastity highlyoPerhaps because people were asked to evaluate the desirability of sexual experience before marriage not fidelity during marriage2Men and women show the differences in mate preferences predicted by parental investment theoryoConsistent differences between men and women in how desirable each gender thinks traits areoAs evolutionary model predicts women value good financial prospects and ambition more than men do and men value good looks more than women dooNo populations in which women value chastity significantly more than men doMen and women differ about the preferred ages of their partnersoEvolutionary reasoning suggests that mens mate preferences will be strongly influenced by reproductive potential of prospective matesoThus we predict that men would choose mates with high fertility or high reproductive valueoA considerable amount of evidence suggests that men consistently seek and marry partners who are younger than they are and that women seek and marry partners somewhat older than themselvesoAs men get older the age difference between them and their wives increasesoAs women get older there is little change in the age difference between them and their husbandsMen and women vary about the preferred number of partnersoWomen are likely to prefer stable committed relationships with men who are willing and able to help care for them and their offspringoMen can afford to be more flexible in their mating tactics which makes them more open to mating opportunities that do not involve longterm commitments Differences in mating tactics may contribute to misunderstandings between men and womenoSome uncertainty arises because you dont know what the other persons intentions areoThis uncertainty generates different kinds of problems for men and womenoA false positive arises if you think that the other person is attracted to you when in fact they arent
