A topic came up at the gym about a push for higher female participation in sports. One side of the argument is straightforward and, to me, completely legitimate: more customers means more revenue. Growing the business is a clear, honest goal. Profit is an honest signal. The other side treats increased female participation as an unqualified good. More women training, competing, and staying active is simply better for everyone. Full stop. I tend to push past the first-order effect. Any large-scale effort that changes incentives and norms will produce results beyond the ones we like to advertise. Some of those results may be positive. Some may not. Pretending only the good ones exist is not serious thinking. The classic illustration is the British cobra bounty in colonial India. Officials offered a reward for every dead cobra in an attempt to reduce the snake population. People began breeding cobras to collect the payment. When the bounty was cancelled, the breeders released their snakes. The cobra population ended up higher than before the policy. Good intentions, clear incentive, disastrous second- and third-order consequences. We now call this the cobra effect. I am not claiming that encouraging more women into sport is identical to a cobra bounty. I am saying that any deliberate push will create effects past the ones that look good on a brochure. I consider myself a free-market guy. In the world I prefer, people flow naturally into the activities they actually want to do. Preferences, interests, and trade-offs reveal themselves without needing heavy-handed encouragement or targets. When we decide in advance that one group’s participation must rise, we risk overriding those natural flows and creating distortions we did not intend. A few second- and third-order questions worth sitting with: If participation targets or marketing heavily prioritise one group, does that quietly change the culture of the training environment for everyone else? What happens to standards, language, coaching style, and the tolerance for discomfort that serious training requires? Does framing sport as something that must be made “more accessible” or “more welcoming” in specific ways risk diluting the very qualities that make competitive sport valuable in the first place? When resources (floor space, coaching hours, class slots, competition categories) are finite, who loses relative share when one demographic is deliberately expanded? What happens to injury rates, performance data, and long-term retention when the average participant profile shifts? How do we handle the biological reality that, in most sports past puberty, the performance distributions of men and women barely overlap? Policies that ignore this create their own distortions. The effects do not stop at the gym door. Time and attention are finite. A sustained cultural push toward higher female participation in sport and training will inevitably interact with other major life domains. A few further questions: What happens to workplace participation and career intensity if more women allocate significant time and energy to structured training or competitive sport? Does it reinforce, dilute, or simply reshape existing patterns of labour-force attachment? How does a stronger emphasis on athletic identity, body composition, and performance interact with decisions around partnership, family formation, and childbearing? Timing of peak training years often overlaps with the years when fertility is highest. Does the cultural signal quietly shift priorities, delay certain life stages, or change the perceived trade-offs? Are there downstream effects on household formation, fertility rates, or the division of domestic labour that no one is currently modelling because the first-order goal (“more women in sport”) looks so obviously positive? None of these questions require hostility to women training or competing. Plenty of women already do both at a high level and benefit from it. The point is narrower: treating “more female participation” as an automatic social good without examining trade-offs is the same mistake as treating a cobra bounty as automatic pest control. The person focused purely on more paying members is at least being transparent about the goal. The person who insists the outcome can only be positive is the one who needs to do more work. History is littered with policies that optimised for the first-order result and then discovered the second- and third-order results were the ones that actually mattered. I’d rather have the conversation that includes the uncomfortable parts than the one that stops at “more is better.”
