Am I missing something here because when I was growing up, this wasn't a thing.
Well, I am 36, and I know what you mean: in our generation there was a lot of absent analysis perhaps, on the mainstream level. And we millennials probably represent one of the last generations where that was the case, I guess. As for me, I was merely shunted in spec ed. departments for about 8 years. The elementary school psychologist thought I had autism. I was developing in a way that was socially abnormal. I didn't make a lot of friends in the k-12 years, except abusive ones, and often wandered the playground alone, for example
I was not ever officially diagnosed with that, but in middle school, I think it was adhd that they wanted to label me with. But by the end of high school, they really wanted to phase me out of all this. Largely, I felt like I was simply 'observed' during those years, more than I was the subject of any kind of more active management. (well in elementary school, there was the trampoline I sometimes was sent to go on)
I have made a few extensive posts on my experience here, but don't really dwell on it. I have read a few books on it though, because the brain is obviously complicated, and puzzle-like, and one probably should read a few books about brain/mind stuff in any case
So you might be able to see from this, why I might want to think about, or read about neurology or psychology stuff at least a little bit. It does bother me if people don't believe that various variations in psychology exist - something like autism can seem invisible to a lot of people, for example. It can even sometimes be quite a puzzle, I think, for the person experiencing it, to get a clear objective view of it
