CLAIM: Romantic love is a near-universal human phenomenon, not a Western invention

CONFIDENCE: ★★★★★ (Established - replicated across multiple methodologies)

KEY EVIDENCE: - Jankowiak & Fischer 1992: Found romantic love in 147 of 166 cultures (88.5%) using ethnographic evidence - 2025 study (PMC11836147): 117,293 participants across 175 countries confirmed romantic love valued universally for long-term relationships - Neuroscience: Consistent dopaminergic activation patterns (VTA, caudate nucleus) across culturally diverse individuals in love

MECHANISM: - Evolutionary: Romantic love evolved as mammalian courtship attraction system to focus mating energy on preferred partners - Neural: Activates dopamine reward pathways (same across cultures) - Biosocial: Universal biological capacity + culturally variable expression

CULTURAL VARIATION: - Nuclear family systems value romantic love more highly - Higher female status correlates with romantic love emphasis - Modernization increases romantic love's cultural importance - Lower SES individuals value romantic love MORE (commitment device for economic vulnerability)

FALSIFICATION: - Would be falsified by finding cultures where romantic love is neurologically impossible - Would be weakened by finding no dopaminergic activation in non-Western populations

SOURCES: - Jankowiak & Fischer 1992, Ethnology (JSTOR 3773618) - PMC11836147 (2025 cross-cultural study, 175 countries) - PMC1764845 (Fisher et al. neuroscience) - PMC12118770 (de Munck biosocial model)
