That there is junk science. Not real science. It’s made up stories written in magazines to get their sales up. No different than the tabloids in line at the grocery store with the headline someone was abducted by aliens.
For one thing, hundreds of billions, if not trillions more dollars have gone to studying other brain conditions, like Schizophrenia, Parkinson’s, Alzheimer’s, etc...and we still have no idea what’s really going on in the brains of folks with these conditions.
In comparison, funding for the study of trannies is not even a drop in the Pacific Ocean.
