The Adaptive Heuristic: Sexual Selection, Deceptive Mimicry, and the Cognitive Ecology of Pride and Prejudice

While traditional scholarship on Jane Austen’s Pride and Prejudice focuses on the socio-economic dynamics of the Regency marriage market, this article adopts a biocultural framework to interrogate the novel as a narrative guide to effectively choosing a mate. The principles of Literary Darwinism inform this study, specifically Sexual Selection Theory, Parental Investment Theory, and Costly Signaling Theory, arguing that the novel functions as an ‘adaptive heuristic’ for distinguishing between ‘honest signals of fitness’ and ‘deceptive mimicry.’ By contrasting the courtship behaviors of Mr. Darcy and Mr. Wickham, the narrative dramatizes the evolutionary problem of ‘cheater detection.’ This study underscores the role played by male short-term and long-term mating strategies, high-status traits and low-status signals, honest resource-holding and insincere displays of affluence that influence female selection. The analysis extends the scope of evolutionary critique to examine intrasexual competition, strategies of ‘competitor derogation,’ and the ‘extended phenotype’ crucial to female habitat assessment. This paper iterates that Austen does not merely critique the social manners of her day, but charts what might be described as the deep biological algorithms of female choice, narratively justifying the heroine’s need for ‘epistemic vigilance’ in a high-risk mating environment.
