When I was in my teens, maybe even early 20s I thought I had a nearly maximally unusual mind - but with more experience with other people (especially in different social groups to mine) I gradually adjusted my views and now, mid 40s I rate myself only as "slightly unusual" in both poll categories.

It's also possible that my mind has changed toward "typicality" but my impression is that I've just developed better coping strategies to deal with situations that would have been a lot more difficult when I was younger.
