Comment on If autism is a spectrum, does that mean everyone is on the spectrum?

The “can’t be more or less blind” thing is based on the concept that blind means “100% totally optical nerve dead blind” and anything that’s not this extreme is not blind but very bad sighted.

The “blindness is a spectrum” comes from the concept of “legally blind”, meaning that there’s a point where you can technically still see something, but for all legal purposes you are counted as blind, because your vision is not good enough to fulfill the requirements for legal use, e.g. for driving.

The real spectrum here is “vision”. Everyone accepts that vision is on a spectrum, and you can have better or worse vision.


Similar things with Autism. The definition of autism originated as a psychological disorder, an illness if you will. That has shifted in the last decades, but at its core autism (like blindness) is a bundle of things that work differently than on neurotypical people.

So while “having autism” like “having blindess” is a binary definition (linguistically speaking), if you look at the things affected by autism and start with the “healthy” variant, all of that is on a spectrum too. And as with the definition of “legally blind” there is a somewhat arbitrary line that defines whether you have autism or not.


As always with almost everything concerning humans, everything is on a spectrum.
