Dr. David Buss on Huberman Lab: Why Men and Women Differ

For long‑term partners, both men and women universally value intelligence, kindness, mutual attraction and love, good health, dependability, and emotional stability (with women emphasizing stability slightly more). In short‑term contexts, physical appearance rises in importance for both sexes; men often lower standards if the encounter is low‑risk and low‑commitment, while women place more weight on traits like status, charisma, and risk‑taking (“bad boy” qualities) than they would in choosing a long‑term partner.

Women more strongly prioritize a partner’s earning capacity, ambition, status, and especially his resource trajectory, because pregnancy and childrearing impose higher biological and opportunity costs on them. Men place greater emphasis on physical attractiveness and youth because cues like clear skin, symmetry, low waist‑to‑hip ratio, full lips, and lustrous hair reliably signal health and fertility—even if men are not consciously thinking in reproductive terms.

Women track the “attention structure”—who gets attention and desire from others—as a status cue, and use mate choice copying: the same man is judged more attractive when seen paired with attractive women or surrounded by female interest (e.g., rock stars and groupies). This makes women’s attraction more circumstance‑dependent than men’s, whose judgments rely more directly on physical and psychophysical cues and are relatively less swayed by context.

In online dating, both sexes commonly misrepresent age, appearance, or qualities that they believe the target finds attractive, using flattering photos and curated profiles. Men, especially those pursuing short‑term sex, often exaggerate long‑term interest, value alignment, and commitment to match women’s stated preferences, while women also selectively present themselves to better fit male preferences. Some critical traits like emotional stability, stress response, smell, and everyday behavior can only be assessed in person and over time, not via text or a single coffee date.

Once long‑term pair bonds exist, jealousy functions to protect one’s investment in a relationship. It is triggered by cues of infidelity, emotional distancing, active mate poachers, or emerging mate value discrepancies (e.g., job loss, sudden fame). People respond with a spectrum of tactics—from monitoring phones and observing interactions to stalking and physical violence—with around 28–30% of married people in the U.S. experiencing intimate partner violence at some point.
