Men have been shown to discount future monetary rewards in several mating contexts, including intrasexual competition. Women, on the other hand, have not displayed differential discounting of future monetary rewards in intrasexual competition contexts. Here, we test the hypothesis that the failure to find delay discounting in women in intrasexual competition contexts may be due to the monetary nature of the reward. Women do not compete with other women for access to men based on monetary status; rather, women compete in other areas, including youthfulness and beauty. In a series of studies, we tested whether women will more steeply discount future appearance enhancing products following an intrasexual competition prime. Results indicated that the intrasexual competition prime did induce intrasexual competition, yet women did not show enhanced discounting a future gain for appearance enhancing products. We suggest that this failure to find enhanced discounting for a future gain may be due to the differential reproductive assurance for women, suggesting sensitivity to the different abundance of mating opportunities for women relative to men, as proposed by Bateman’s principle.

内在竞争的女性不会对未来外观增强产品有不同的折扣

事实证明，在包括性竞争在内的多种交配环境中，男人会折衷未来的金钱奖励。另一方面，女性在两性竞争中没有表现出对未来金钱奖励的不同折扣。在这里，我们检验了以下假设：在性别竞争中未能找到女性的延迟折扣的原因可能是奖励的金钱性质。妇女不与其他妇女争夺基于金钱状况的男子身份；相反，妇女在其他领域竞争，包括青春和美丽。在一系列研究中，我们测试了女性在进行性竞争后是否会大幅降低未来增强外观的产品的折扣。结果表明，性竞争竞争确实引起了性竞争，然而，女性并没有表现出更大的折扣，将来会获得外观增强产品的收益。我们认为，未能找到增加的折价以获得未来收益的原因可能是由于妇女对生殖的保证不同，表明对妇女相对于男子的不同交配机会的敏感性，这是贝特曼原则提出的。
