I hadn't heard of epistemic injustive before, but I've seen that used against queer people so many times. So many people ask queer people "But what if you're wrong?" as if there's some kind of fine or prison sentence for incorrectly identifying as not cis or straight. Cishet people never get asked those questions even though incorrectly thinking you're cishet when you're not is far more damaging. The implication is that it's better to incorrectly think you're cishet than to correctly think you're queer. It was far more common throughout history for queer people to lead double lives or go through life not understanding themselves, but some people expect us to believe that us being wrong about ourselves is a bigger danger/risk than living a lie.

So much of the same goes for neurodivergent people. There were decades where people had little awareness about autism, ADHD, OCD etc. People went decades struggling and having no idea why. I got diagnosed with ADHD at 42. I paid 1000 GBP for a two hour assessment with a psychologist with 20 years experience because I knew I would have too many doubts about the diagnosis if I got it through a 30 minute Zoom call with a nurse that most of the people that go through the NHS end up getting. When the medication started working for me I realised how much anxiety I got from having neurological hyperactivity, but I still sometimes have doubts that the diagnosis was a mistake even though it clearly wasn't. But still, we must think about all the poor neurotypicals that are being overdiagnosed.
