Episode notes
Sociosexuality Predicts Infidelity Risk
- High sociosexuality predicts greater infidelity risk because desire for uncommitted sex persists after settling.
- Past partner count often proxies this trait and correlates with higher cheating rates.
Dark Traits Coexist With Attractiveness
- Dark triad traits (narcissism, psychopathy, Machiavellianism) associate with higher affair rates.
- Narcissists often appear attractive because they invest in grooming and project confident signals.
Infidelity Has Biological And Social Roots
- Infidelity shows partial heritability because traits like risk-taking and sexual desire have genetic components.
- Family and friend environments also shape norms that increase cheating risk.
