Contrary to evolutionary psychology's emphasis on matching 'mate value' (e.g., a 7 with a 7), research shows that mismatched couples (e.g., an 8 with a 5 in attractiveness) are no more likely to break up, be unhappy, or cheat. The initial perceived value difference does not predict long-term relationship success.

In modern dating, stating a preference (e.g., for body type or neurodivergence) is often labeled as fetishization. Conversely, stating what you don't want is seen as exclusionary, creating a no-win scenario for being honest about attraction.

Data shows high-status men practice assortative mating, pairing with women of similar educational and economic standing. The "rich man marries the young, beautiful waitress" trope is a myth; successful men value partners they can relate to intellectually and who understand their world.

Men often leverage their financial success as a primary tool of attraction in dating. In contrast, successful women frequently downplay their wealth due to a conditioned fear of being pursued for their money rather than their character—a concern their male counterparts rarely share.

People are more attracted to partners who are passionate about something—anything from trains to art—than to those with prestigious but unloved careers. Shared enthusiasm creates a stronger bond than shared professional status.

The traits that make someone desirable for short-term encounters, like conventional physical attractiveness, are largely irrelevant to their quality as a long-term partner. People who have many short-term partners are not inherently worse at long-term commitment. The two skillsets are independent, challenging the 'alpha vs. beta' dichotomy.

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.

Speed dating studies show couples who "click" are biologically in sync, even if a person violates the other's stated preferences (e.g., height, religion). This highlights the limits of algorithm-based matching, which cannot capture this multi-sensory phenomenon.

A study found that men’s real-world sexual success was highly correlated with how intimidating other men found them, not by how attractive women rated them. This suggests female mate choice is less about direct selection and more about passively choosing the victors of intra-male competition, validating a 'male competition theory' of attraction.
