Ong and Wang's research paper, "Income attraction: An online dating field experiment," investigates gender differences in preferences for a partner's income before interaction. Using a large Chinese online dating website, the researchers created artificial profiles with randomly assigned income levels and tracked the number of visits each profile received. The study found that men visited female profiles regardless of income, while women showed a strong preference for male profiles with higher incomes, especially those earning more than themselves. This "income attraction" could explain marriage and spousal income patterns, highlighting the importance of income as a factor in mate selection, particularly for women.
Hughes, Dispenza, and Gallup's 2004 study explored connections between voice attractiveness, body morphology (shoulder-to-hip ratio (SHR) in men and waist-to-hip ratio (WHR) in women), and sexual behavior. They found that more attractive male voices correlated with larger SHRs, while more attractive female voices correlated with smaller WHRs. Furthermore, for both sexes, voice attractiveness was linked to earlier sexual debut, more sexual partners, and a higher number of extra-pair copulation (EPC) partners. In terms of morphology, a larger SHR in men was associated with earlier sexual activity and more partners, whereas a smaller WHR in women was linked to later sexual debut and fewer partners, suggesting that voice attractiveness may signal fitness and reproductive potential.
