Yeah, I get that shared cultural aspects (including prenatal) are hard to tell from inherited. In this particular case of someone seeking therapy for a specific issue that troubles them, I would expect that the situation can be uncommon enough to stand out in twin studies if the cause is genetic. I am no expert though.

It’s not just hard in practice, it’s a question that the studies are theoretically incapable of answering.
