Rather unexpectedly, the idea of separate sports for males and females has become massively controversial—a major flashpoint in the culture wars, and even in the recent US election.

So what does the evidence say? Is it fair if trans women (who are biologically male) compete with females in sports like swimming, or even boxing? How much sporting performance does a lifetime of testosterone grant you? In this paid-only episode of The Studies Show, Tom and (confirmed sport-hater) Stuart look at the evidence on male vs. female sport performance—and discuss whether the argument is really more about ethics and politics than scientific evidence.


Every week, Tom Chivers and Stuart Ritchie pull apart the biggest arguments and most confusing claims making headlines. Science Fictions isn't just about celebrating breakthroughs; it's a necessary dive into the messy, contested, and often surprising realities of how science actually works. You'll hear them unpack heated debates, examine questionable studies, and explore why even solid research can sometimes lead to public confusion. This podcast serves as a guide through the noise, separating compelling evidence from overblown narratives. Each episode feels like a conversation with two deeply informed friends who aren't afraid to ask tough questions, offering clarity on topics that matter. For anyone curious about the stories behind the science headlines, this is an essential listen. Tune in for thoughtful analysis that goes beyond the press release, grounded in a genuine fascination with how we know what we know.
