Dominant theorizing and research surrounding the operation of intersexual selection in evolutionary psychology tends to be guided by an adaptationist framework and aligned with models of sexual selection involving direct benefits (e.g., parental care) and indirect "good gene" and condition-dependent benefits. In this way, evolutionary psychologists more often espouse Alfred Russel Wallaces' utilitarian viewpoint that traits become attractive because they honestly signal vigor and vitality, which gives priority to natural selection. In doing so, Darwin's esthetic perspective originally articulated in and alternative models of sexual selection (e.g., Fisherian runaway), are given less consideration. This is despite some informative reviews on the topic in evolutionary psychology. In the current conceptual analysis, we discuss the potential of Prum's Lande-Kirkpatrick (LK) null model of sexual selection to help make sense of some of the mixed evidence regarding the links between attractive traits and purported markers of phenotypic and genetic condition. We then consider how the implications of the LK null model can help to shift theoretical assumptions and guide future work in evolutionary psychology on intersexual selection.
进化心理学中关于两性选择运作的主流理论和研究往往受适应主义框架的指导，并与涉及直接利益（如亲代抚育）以及间接“优质基因”和条件依赖型利益的性选择模型相一致。通过这种方式，进化心理学家更常支持阿尔弗雷德·拉塞尔·华莱士的功利主义观点，即性状之所以具有吸引力是因为它们诚实地表明了活力和生命力，这优先考虑了自然选择。这样一来，达尔文最初于[具体年份未给出]阐述的美学观点以及其他性选择模型（如费希尔失控选择）就较少被考虑。尽管进化心理学领域有一些关于该主题的有益综述，但情况依然如此。在当前的概念分析中，我们讨论了普鲁姆的兰德 - 柯克帕特里克（LK）性选择零模型有助于理解有关迷人性状与所谓表型和遗传条件标志物之间联系的一些混合证据的潜力。然后，我们考虑LK零模型的含义如何有助于转变理论假设，并指导进化心理学未来关于两性选择的研究工作。
