I found this article very interesting, because I feel that I fall in the category of people that think they have it, although I probably don't. My psychiatrist who is not an expert on autism told me I display autistic traits but that doesn't necessarily put me on the spectrum. Also my RAADS-R scores fall into the autistic spectrum but on the low end. Another psychiatrist diagnosed me with OCD. I am in my late 20s and I don't see how I could ever know for sure or if I am autistic or not, but nowadays most people in my country would say "we are all somewhat autistic in some way or another"
