This is really interesting if these stats are true. Just to comment on the raising child as different gender, I personally would put this down to wider societal influence as the parents of course dont have full control of what their child is exposed to - they can only control so much. This could be things like bullying, advertisements, minor subtleties present in society (such as the signs used on gendered toilets) and probably others. But just want to be clear that i dont think your conclusion is invalid by any means, just wanted to give my viewpoint on that specific stat in case you hadn't considered it already and maybe we can learn from each other :)

The identical twin study specifically sounds really interesting and I'd love to read about it if you get the time to link it, thanks!

I was actually repeating what was said in a video I watched yesterday so I went to look at their sources - here is a relevant study that supports this conclusion - https://www.sciencedirect.com/science/article/abs/pii/S1743609515339060

However while looking it up in google scholar I did find another study that concluded the opposite, that there's no significant difference between identical and fraternal twins. That study is here. https://www.nature.com/articles/s41598-022-17749-0

So it's possible that I was misinformed.

As a bonus, here's an interesting analysis about what even is gender and gender identity in an academic setting. https://academic.oup.com/analysis/advance-article/doi/10.1093/analys/anad027/7204699

I searched pubmed and I’m pretty sure this is anecdotal, unfortunately. Hard to say how much of the volume of non-straight/trans and trans/trans twins on social media is selection bias since the trans/cishet twins aren’t eye-catching. There seem to be a lot but gosh do folks love to hear about twin similarities. It’s worth noting most are fraternal but that’s consistent with the general population.

I understand where Kamirose is coming from, but it’s not empirical (unless there’s a study that used some really weird terminology and I missed it).

Edit: I found a review and its citations do not converge well due to small sample sizes (hard with trans + twins - two rare things for births).

I did a websearch for trans twins and found the following 2 links. I did not read them just sharing as it seems you didn't have good luck searching.

Thanks for the extra legwork! These are cited by the review. I’m hopeful that there will be more research and data available on gender dysphoria as time goes on with more people being able to seek gender affirming care. 🤞 the horrific backlash doesn’t scare too many into staying in the closet or stymie funds/grants to these efforts.
