Thanks, Luca. I'll think about that. I appreciate the inclusion.
I notice that definitions of autism can be very idiosyncratic sometimes. I guess that makes sense, given the nature of autism.
Originally, I based my self-assessment on some Youtube videos that talked about "signs that you might be autistic." I devoured those videos and made a long list of potential signs. As the signs accumulated, I came to the conclusion that, indeed, I might well be on the autistic spectrum.
However, as I learned more, I realized that these "signs" often lacked specificity and differential diagnostics. That is, they only provided broad labels without clarifying 1) how that manifested in people with autism, and 2) how that differed from other, more common issues/traits.
For example, one alleged sign of autism is "being blunt and straightforward." I initially thought, "Well, I can be blunt and straightforward sometimes, so I'll put that on the list." However, as I learned more about autism, I realized that there was a big difference between my bluntness and autistic bluntness. With autistic bluntness, it's a matter of social-emotional perceptions, facial expression, etc. My bluntness is different; it's a deliberate choice and a departure from the norm. Typically, I'm sensitive to how the other person is perceiving me, and I try to phrase/communicate things in a nuanced way, so they aren't hurt or offended. But I've also learned over the years to be direct and blunt when I need to be. When I choose to be blunt, I'm very aware that I am making a deliberate choice to do that, and that the other person will perceive me as blunt or uncaring, and they will probably be put off.
That's just one example. I could multiply it 30 times -- disliking small talk, discomfort in social situations, difficulties making friends, having different interests than others, having a routine, etc., etc. I needed more information before I realized that my version of these problems/traits fell more in line with "simple" introversion, social anxiety, and the like, rather than autism.
Also, I realized that I am missing some of the defining features of autism (e.g., difficulties with social initiation and response, difficulties with non-verbal communication, atypical speech and movements, strict routines and resistance to change, unusual interests).
Anyhow, that's enough about my self-diagnostic
mishaps journey. I do appreciate the friendliness and welcome of you and many other people here.
