If I remember right she did a video about trans healthcare and kept referring to a shitty study that was either disproved or had some other issue that made it mostly dismissed by mainstream psychology. She is a physicist not a psychologist and she’s even criticized people for speaking outside their field at one point, then she made a video blowing the risks of transition for trans people way out of proportion. She also just didn’t use or didn’t know about multiple studies showing transition is an effective and accepted treatment for gender dysphoria, basically disagreeing with the general consensus on the effectiveness of transition. I don’t recall all the details but it was at that point I just stopped paying attention to her stuff. I think she’s also been criticized for kinda shitting on niche studies as “for funsies” projects because the existing science disagrees with the hypothesis, which is no reason to not try something. Like string theory and stuff like that.
The second link was exactly what I was thinking of, thanks for finding those!
