The Brutal Tactics of Female Sexual Competition - Dr Dani Sulikowski - #1064

How do you frame your research, and what’s the core aim of female intersexual competition? Is it a gas pedal on your own success or a brake on rivals?

I study evolutionary psychology with a focus on female intersexual competition, which is about winning relative, not absolute, reproductive success. You can raise your own odds or curb a rival’s, and people often act on these instincts without conscious awareness.

Women feel the nastiness but rarely link it to fertility stakes; how does appearance fit into this?

Physical attractiveness drives female mate value, so looks become a battlefield. Much of dressing up signals status and aggression to other women, not men, which is why a sexy entrance can trigger social pushback and why many women quietly dress down when joining new groups.

How does this differ from men’s competition if both sexes chase reproductive payoff?

Male competition skews toward maximizing their own output, while female competition heavily includes suppressing rivals because female reproduction is capped and costly. Think of men sprinting in lanes, while women run and also trip opponents, where the winner is whoever finishes highest even if everyone runs slower.

So that brake pedal helps explain a lot of sex differences in social behavior.

Yes, it’s an organizing principle of female social life, with women typically excelling at alliance tracking, subtle manipulation, and reading social cues that many men miss.

How does this show up in women’s dating advice when it’s framed as empowering?

In studies, women recommend more fertility-suppressing choices to other women than they endorse for themselves—delay kids, prioritize career, return to work fast, downgrade monogamy. You can see the same themes echoed across media memes that glamorize breakup and infidelity.

The justification sounds liberating and risk-aware, but the tell is when advice diverges from personal behavior, right?

Exactly—there are winners who preach but do not fully live it, and losers who embody it and pay the cost. A stark case is young women choosing sterilization, later seeking reversals at notable rates, often after being celebrated online for the decision.

Is elite support for LGBT and gender ideology also part of fertility suppression?

I think so, and women often drive it in female-dominated sectors. There’s also an adaptive window where teens should delay reproduction, which modern messaging can hijack; and manipulative signaling sometimes backfires into self-harm, despite being sold as freedom and fun.

Do suppression strategies ever target men, or is the payoff mainly through women?

You might sabotage a rival man to poach his partner, but male-focused suppression rarely moves population-level reproduction. Broad fertility suppression of women can, and I argue we’ve seen cycles like this before, including in Rome’s late-stage attempts to bribe women back into motherhood.

If this hurts so many, why hasn’t evolution patched women’s susceptibility to it?

Because it benefits winners, not losers. It tends to surface in affluent, safe eras, creating an effective bottleneck where the biggest change is more women having zero children.

Can we even talk about birthrates and motherhood without backlash?

It’s the third rail because it hits the strategy’s heart; everything else—bad relationship advice, glamorizing single motherhood, even hair and style nudges—ultimately serves lower fertility, and fatherlessness worsens outcomes for kids.

What about the workplace and the argument that more women in institutions is good by default?

A small, non-democratic critical mass can reshape norms well before half the staff are women. At the societal level, sub-replacement fertility is terminal; at the individual level, data consistently link greatest wellbeing to married mothers, not childless singles.

Name a tactic people miss.

Branding masculinity as toxic undermines traits women actually prefer in protectors and providers, discourages men from policing bad actors, and shames benevolent, pro-courtship norms—making high-quality men harder to identify.

Isn’t that just tastes shifting over time?

No—the costly, reliable signals get suppressed and replaced with cheap ones, so women pair with men their instincts later reject, leading to churn instead of families.

Blanket rules also spook cautious guys; many now avoid approaching, yet most women still want men to initiate.

Exactly, and stalling initiation stalls courtship. Once the guardrails vanish, the environment turns anti-natal; elites lose least from the slowdown, while rivals age out.

Genes chase relative gains, even if society pays later.

And the end is not the end for winners—they become founders of the next expansion. As chairs dwindle, incentives intensify to hasten collapse; feminized institutions flatten merit and speed decline by design, not by accident. I’m skeptical of the mismatch story because our modern world is the human extended phenotype, and these cycles recur.
