For a reproductively suppressive ideology to be an effective competitive strategy, some women must genuinely adopt it (the 'losers'), reducing their reproductive success. This creates a relative advantage for the 'winners' who promote the ideology but do not follow it themselves.

Strategies that make mating more difficult—such as devaluing marriage or masculinity—create a hostile environment. While this hurts everyone, it harms those with lower mate quality more severely, raising the bar for entry and creating a relative reproductive advantage for the elite.

As a competitive tactic, women advise female rivals to delay having children and prioritize their careers more heavily than they would for themselves. This serves to subtly suppress the reproductive success of competitors under the guise of helpful advice.

The speaker introduces "mate suppression" as a twisted biological impulse, particularly prevalent in toxic femininity, to harm the reproductive chances of perceived rivals. This drive manifests in behaviors that sabotage others' attractiveness or access to mates, explaining seemingly irrational social rules that secretly aim to handicap competitors.

Female competition involves suppressing rivals because female reproduction is capped and vital for population survival. Male competition is a 'sprint' to maximize personal success, as suppressing one rival is futile when a few men can easily repopulate and pick up the slack.

By branding traditionally attractive masculine traits like dominance and aggression as 'toxic,' women can manipulate the mating market. This sabotages rivals' ability to select high-quality partners by steering them toward less desirable mates, thereby inhibiting their reproductive success.

Human societies are not innately egalitarian; they are innately hierarchical. Egalitarianism emerged as a social technology in hunter-gatherer groups, using tools like gossip and ostracism to collectively suppress dominant 'alpha' individuals who threatened group cohesion.

In subsistence societies, women invest all resources into their own offspring. Only in affluent, safe societies do women accrue enough surplus resources (time, energy, capital) to make investing in the suppression of rivals a more adaptive strategy than investing further in their own reproduction.

The "having a boyfriend is cringe" trend, promoted by high-status women, may be an unconscious evolutionary strategy to suppress the reproductive success of other women, thus reducing competition for desirable partners.
