Parent–offspring conflict over mating: The case of short-term mating strategies

Abstract

Individuals solve problems of reproduction by engaging in long-term and short-term mating. Short-term mating strategies have both costs and benefits, but their costs are higher for parents than they are for offspring. On this basis, three hypotheses are formulated: first, individuals consider short-term mating strategies more acceptable for themselves than for their offspring. Second, parents consider short-term mating strategies less acceptable for their daughters than for their sons. Finally, men consider short-term mating strategies more acceptable than women. To test these hypotheses a within-participants design is employed, whereby sexually mature individuals with children are asked to rate the acceptability of a set of short-term mating strategies for themselves and for their offspring. Evidence from a sample of 295 British parents provides support for all three hypotheses.
