Abstract
This study explores the impact of perceived sex ratios on dating behavior and mating strategies, introducing the Dating Equilibrium-Shift Hypothesis (DESH). DESH posits that individuals of the less numerous sex gain greater bargaining power in romantic interactions, thereby shaping the mating strategies of the more abundant sex. To test this hypothesis, a laboratory experiment was conducted with 136 participants (79 men, 57 women) using a simulated dating app. Participants were assigned to one of three manipulated sex ratio conditions: male-scarce, female-scarce, and balanced (control). They evaluated 50 profiles based on attractiveness, indicating their interest with a like, and assessed their willingness to commit to a long-term relationship. The results revealed that in female-scarce conditions, men exhibited lower selectiveness, with an 11.89% decrease in the likelihood of giving a like. Conversely, in male-scarce conditions, men became more selective relative to the female-scarce group, showing a 17% lower likelihood of giving a like, consistent with DESH predictions. Although no statistically significant differences were observed in the willingness to commit to long-term, the data suggest a pattern that aligns with theoretical expectations. Due to technical issues, data for women in male-scarce conditions were incomplete, limiting the interpretability of findings for this group. Despite this constraint, the study integrates evolutionary and economic perspectives to advance our understanding of mating dynamics and underscores the influence of sex ratios on dating decisions in digital environments.
