Modern WisdomThe Hidden Truth About Our Collapsing Birth Rates - Mads Larsen
At a glance
WHAT IT’S REALLY ABOUT
Evolution, Dating Markets, And The Civilizational Cost Of Collapsing Births
- Mads Larsen discusses the global fertility collapse, arguing that modern dating markets, women’s increased independence, and contemporary ideologies of love have unintentionally created conditions where people can’t or won’t have the children they actually want.
- He explains, from an evolutionary psychology perspective, how female mate preferences in a freely chosen, promiscuity-enabled mating market lead to a concentration of mating opportunities among a minority of high-status men and widespread involuntary singlehood among others.
- Larsen contends that replacement-level fertility is not simply an economic or lifestyle issue but an existential risk comparable in scale to other X‑risks, with societies on track to lose the majority of their population within a few generations.
- He criticizes current researchers and policymakers for downplaying the problem, calling instead for cultural experimentation, better understanding of mating and reproductive psychology, and new dating norms that preserve women’s freedoms while making family formation more feasible.
IDEAS WORTH REMEMBERING
5 ideasLow fertility at current levels leads to rapid population collapse within a few generations.
A fertility rate of 1.4 means each generation is about one‑third smaller; extrapolated over three generations, societies can lose 60–70% of their population, with extreme cases like South Korea heading toward effective depopulation.
Modern mating markets systematically exclude many men while over‑rewarding a minority.
With individual partner choice and dating apps, women’s more selective promiscuous attraction system funnels attention toward high‑value men, leaving a growing share of men with few or no mating or relationship opportunities, which depresses family formation.
Women’s economic independence changes what counts as an attractive or acceptable partner.
Because many women no longer need men for material survival, the evolved pull to pair‑bond with an average man in harsh conditions is weakened; in an abundant, choice‑rich environment, standards rise and more men fall below the threshold for partnership and parenthood.
Policy tools focused on cash incentives to parents have limited impact on birth rates.
Evidence from multiple countries suggests that direct financial transfers can only move fertility marginally and at extremely high cost per additional child, because the deeper drivers are psychological, cultural, and structural—not just economic.
Contemporary ideology of ‘confluent love’ undermines long‑term, child‑centered relationships.
The current norm of serial monogamy and individual self‑realization—staying together only while it “works for me”—reduces social pressure and cultural scripts that once steered couples into stable pair‑bonds and parenthood.
