For professional men, cosmetic procedures are increasingly tied to career longevity. Galloway argues that appearing youthful and vigorous is becoming a proxy for economic viability, shifting the motivation from simple vanity to a strategic career investment.

Men engaging in extreme beautification trends ('looksmaxing') often focus on traits that other men find formidable, such as a strong jawline. This intrasexual competition strategy may not align with what women actually find most attractive, which can be a slightly more feminized face on a masculine body.

Men have fewer socially acceptable ways to enhance their attractiveness compared to women, making female judgment based on looks seem "unfair." This has fostered a cultural myth that women don't care about men's appearances, reframing a natural response as a shallow choice.

Men's pursuit of extreme muscularity and masculinized features is often a failure of cross-sex mind reading. They are coding for formidability and respect from other men, whereas research suggests women often prefer a more neutral or even slightly feminized face combined with a masculinized body.

Much of female fashion and beauty effort is a form of intrasexual competition. It signals status to other women and serves a "mate guarding" function, as studies show men are often less discerning about the nuanced differences in high-status attire.

Studies indicate that when viewers know an erotic image is machine-made, they find it less arousing. This suggests a powerful "reality premium" where human authenticity holds unique value, potentially limiting the complete replacement of human performers by AI in creative and personal domains.

The concept of a universal "mating market" is flawed because attractiveness is highly subjective. As people get to know each other, their agreement on who is desirable drops to a mere 53%, barely better than chance. One person's '10' is unlikely to be someone else's.

The idea of a universal attractiveness scale (e.g., '10s' vs. '2s') only applies to initial encounters with strangers. As people get to know each other over time, their opinions on who is attractive diverge significantly. This allows individuals to find partners they personally rate as a '10', even if others don't agree.

In studies where people "buy" traits for an ideal partner with a limited budget, sex differences amplify. When forced to make trade-offs, men allocate more budget to physical attractiveness, while women allocate more to resources and status, revealing fundamental, constrained mate preferences.
