I'm going to start a thread collating expert responses to the IOC's sex testing policy. Please feel free to reply with additions. I'm more interested in the views of scientists than lawyers or philosophers, but everything counts.

Even if the IOC won’t listen to the people affected by its decisions, we might at least expect it to listen to professional experts when they say that it’s got this very badly wrong.

if you want to know the history of this kind of policy, I made a podcast two years ago that explained why these tests make no sense, how they were already used and eventually abandoned by the IOC in the 80's and 90's, and the devastating impacts they have on real athletes: www.tested-podcast.com

Human rights lawyer and former Olympian Nikki Dryden says “it creates a culture where someone like a coach, an official, or even another parent, feels entitled to question whether your daughter ‘looks female enough’ to belong. That is not protecting women’s sport. That is policing girls’ bodies.”

The Guardian (Australia) notes today that the new IOC rules fly in the face both of international law, including international human rights law, and the scientific evidence on sexed bodies.

Tranathon is a tiny campaigning group of UK trans people fighting for equal participation in sport. We have observed with dismay the increasingly hostile environment facing trans people who wish to engage in sporting pursuits with their peers at any age and at any level,

Sex testing doesn't protect women - it targets and harasses women, replacing fairness with fear, science with stigma, and equity with exclusion. All women should feel safe and protected in women's sports. We stand together and will fight together.

At Tranathon we know that as trans people we are the targets of this policy. But we also know that this is a racialised form of gender violence and that Global Majority women in particular will be targeted first, worst and always.

It is deeply disappointing to see the IOC decide to sweep these well-documented problems aside in the pursuit of an ideological campaign to prevent a tiny group of women from ever participating in sport.

Sex verification is not a novel concept in sport, with the IOC and IAAF having required chromosome testing in women's events from the 1950s to the 1990s. This approach was contested by participants, scientists and human rights bodies. It was eventually discontinued on grounds of

Tranathon member Bridie says: “Running has been increasingly important to me over the last few years. It keeps me fit and well, and it helps my bone health, which can sometimes be an issue for trans women - especially if, like me, they were bullied in PE at school and did no sport until adulthood.

Liz Truss wanted to abolish the Equality Act because she mistakenly thinks “it says whether you’re a woman or whether you’re Black or whether you’re gay is more important than what your talents are.” Is it any surprise then that she turned the EHRC into a vehicle for anti-trans politics?

Transphobes have tried to push trans people out of events like these, but we are here to show we belong and are welcome in these spaces, just as we should be welcome everywhere. We look forward to showing our results and sharing our experiences with you.

They just think trans people are fake. Simple as that. The whole “advantage” idea is a distraction from that core belief which can be dropped in a heartbeat when they don’t think they need it anymore.

Here we see one of the more prominent anti-trans campaigners in the US stating the reality of the trans people in sports “debate” openly. It’s not about “advantage”, it’s about their belief that societal systems MUST treat trans people as their sex assigned at birth in all cases.
Quote tweet by Riley Gaines in response to Erin Reed pointing out her support for banning trans women from chess. It reads: “Of course I do. I worked alongside leadership within to make sure of it. Women's opportunities are meant for women, full stop. Men shouldn't be in women's category in chess, pool, or any sport.

Why even have women's category in the first place if men can play wherever they want?”

We would encourage trans people to sign up for their local Parkruns, not just to make use of this wonderful resource, but to show that we are welcome and belong in these events just as we belong in all areas of public life.

They rightfully point out that, just as with proposed restrictions on trans people's access to public restrooms, enacting trans exclusionary policy would require invasive and impractical checks of peoples' gender. support.parkrun.com/hc/en-us/art...
It is not appropriate or practical for us to request proof or adjudicate the validity of a person’s gender identity, just as we would and could not ask every single one of our 8 million registered participants to evidence other stated details, whether that be their name, age, postcode or activity level. Our position, therefore, is that we publish results based on a person’s self-declared information, including gender.

Parkruns are a wonderful opportunity for community and exercise that should be open and welcoming to all. These groups seek to change that. We are glad that Parkrun has stood firm on this matter, making clear on their website that they retaining their self-identification policy.

Transphobia in sports has largely centred around high-level professional sports and school sports (and those are also discriminatory). But they are now expanding to any public physical activity. This is an effort to expand anti-trans bigotry into wider aspects of public life.

Right here is a clear example of what we're trying to fight against. Anti-trans groups have recently made a push to target local parkruns (the free-to-enter, non-competitive, mixed-gender events) for basic trans inclusion. www.thepinknews.com/2023/10/02/p...

Modern transphobia has often centred around sport, including public mixed-gender events such as these. We’re trying to push back against that by encouraging and celebrating trans participation in running.
