Founder Effect and Post‑Collapse Selection

Danielle Sulikowski, professor of evolutionary psychology, presents a controversial theory on why global fertility rates and birth rates are collapsing.

She argues that an evolutionary strategy known as female mate suppression—where dominant women repress the reproductive success of rivals—has shifted in humans into a modern form of antinatal social contagion.

Rather than direct biological suppression, the strategy manifests as propaganda and cultural messaging that discourage motherhood, promote career over family, and accelerate population decline.

We explore how intrasexual competition among women could shape civilization itself, why some groups might defect against their own society to gain an evolutionary edge, and how this connects to broader debates in feminism, cultural evolution, and civilizational collapse.

The conversation also ties in the density-dependent dynamics of Calhoun’s Rat Utopia experiments as a possible parallel to modern urbanization, social media, and declining birth rates.PATREON https://www.patreon.com/c/demystifysciPARADIGM DRIFThttps://demystifysci.com/paradigm-drift-showOUR HOMEBREWED MUSICCheck out our band's new album:https://secretaryofnature.bandcamp.com/album/everything-is-so-good-hereVinyl pre-orders available now: https://buy.stripe.com/14A5kC3Od5d21Ms7zPdEs0900:00 Go!
