Essentials: How Humans Select & Keep Romantic Partners in the Short & Long Term | Dr. David Buss

October 2, 2025

Key Takeaways Copied to clipboard!

  • Mate selection criteria differ significantly between short-term and long-term relationships, with universal traits like intelligence and kindness desired for long-term commitment, while men prioritize physical attractiveness/fertility cues and women prioritize resource acquisition/status cues. 
  • Sexual selection operates via two pathways: intra-sexual competition and preferential mate choice, where the preferences of one sex set the competitive ground rules for the other. 
  • Jealousy is an evolved emotion serving a mate retention function, activated by threats like infidelity cues or perceived mate value discrepancies, which can lead to behaviors ranging from vigilance to violence.

Theoretical Framework of Mate Choice

(00:01:01)
  • Key Takeaway: Sexual selection, stemming from Darwin, explains mate preferences through intra-sexual competition and preferential mate choice, where preferences set the rules for competition.
  • Summary: Mate choice theory stems from Darwin’s sexual selection, which addresses evolution due to mating advantage rather than survival advantage. This occurs via intra-sexual competition (success in same-sex battles) and preferential mate choice (opposite sex favoring desired qualities). These two processes are related, as one sex’s preferences dictate the competitive landscape for the other sex.
Universal and Sex-Differentiated Preferences

(00:03:31)
  • Key Takeaway: Long-term mates universally desire intelligence and kindness, but women prioritize resource acquisition capacity and slightly older age, while men prioritize physical attractiveness and youth.
  • Summary: A 37-culture study found universal desires like intelligence, kindness, and emotional stability in long-term mates. Women prioritize traits indicating resource acquisition, such as ambition and social status, due to the high biological cost of reproduction. Men prioritize physical attractiveness, which signals youth and fertility, leading to preferences for somewhat younger women.
Deception and Assessing Stability

(00:10:31)
  • Key Takeaway: Both sexes use deception in mate selection, often exaggerating alignment in values, and assessing long-term emotional stability requires observing stress response during shared travel.
  • Summary: Both men and women lie in online dating to embody desired mate preferences, often posting misleading photos. Women rely on auditory and olfactory cues more than men, who focus heavily on visuals. Assessing critical traits like emotional stability is best done over time, such as during travel, to observe reactions to stress.
Short-Term vs. Long-Term Selection

(00:13:50)
  • Key Takeaway: In short-term mating, women are more attracted to ‘bad boy’ qualities and mate-copying cues, whereas men maintain a focus on physical cues but may lower standards for low-commitment sex.
  • Summary: Physical appearance becomes more important for women in short-term mating contexts. Women are more attracted to risk-taking or arrogant qualities in short-term partners compared to long-term partners, where ‘good dad’ qualities are prioritized. Men’s attraction remains relatively context-independent, focusing on psychophysical cues.
Jealousy and Mate Value Discrepancy

(00:17:27)
  • Key Takeaway: Jealousy functions as a mate retention mechanism activated by infidelity threats or looming mate value discrepancies, motivating behaviors from vigilance to violence.
  • Summary: Jealousy is an evolved emotion designed to guard against losing a long-term mate investment. It is triggered by infidelity cues or when a mate value discrepancy opens up, such as one partner’s career success. Responses to these threats range across a spectrum from monitoring behavior (vigilance) to physical violence.
Dark Triad and Stalking Motivations

(00:20:58)
  • Key Takeaway: Individuals high in Dark Triad traits (narcissism, Machiavellianism, psychopathy) are often sexual deceivers and harassers, and stalking is frequently a mating motivation where the stalker has lower mate value than the victim.
  • Summary: The Dark Triad traits correlate with sexual deception and coercion, particularly when combined with a short-term mating strategy. Criminal stalking is predominantly perpetrated by men (about 80%) motivated by a desire to regain a relationship or sabotage the victim’s future mating prospects. Stalkers often have a lower perceived mate value than their victims.
Self-Assessment and Mate Value

(00:27:42)
  • Key Takeaway: Self-esteem is hypothesized to be an internal monitoring device tracking an individual’s mate value, which is assessed both consensually by a group and individually based on specific preferences.
  • Summary: Secure attachment styles are conducive to long-term stability, while avoidant and anxious styles can introduce relationship difficulties. People generally possess an intuitive sense of their own mate value, which self-esteem may track following status changes. Mate value includes both consensual ratings and individual components tailored to specific partner preferences.
Evolutionary Psychology and Neuroscience

(00:31:19)
  • Key Takeaway: Evolutionary psychology provides ultimate explanations (function and selective forces), while neuroscience provides the underlying machinery, and these fields are converging to explain behavior.
  • Summary: The convergence of evolutionary psychology and neuroscience is anticipated, as the former explains evolved function and ultimate causes, while the latter details the underlying neural machinery. Dr. Buss’s recent book, ‘When Men Behave Badly,’ addresses sexual conflict, deception, and harassment.
