I remember how years back, I had a cap with a tag on the underside that claimed, “One size fits all!” At the time, even as a child, this was puzzling. Did it have some kind of elastic property to it that wasn’t immediately obvious? Did it have a strap on one side that could shrink or enlarge the fitting? Or was it something else beyond my understanding? It turned out there was nothing particularly special about it and it most certainly will not fit properly on everyone who tries to put it on. Autism refers to a very broad spectrum. There are people within the spectrum who are fully capable of registering and understanding the materials I read and write on a regular basis, there are others far beyond my own level of language and comprehension, and then there are others who barely register their immediate surroundings at all.
There’s no one, singular face of Autism. We are many, and there’s not one, nice, neat little way of summing up what an Autistic person that you meet will actually be like. This is a hard truth for researchers and scientists, no matter what their field of expertise: trends and labels are convenient and easy to read, but they aren’t always truly reliable.
