Neuroscience A low-cost tool accurately distinguishes neurotypical children from children with autism just by watching them copy the dance moves of an on-screen avatar for a minute. It can even tell autism from ADHD, conditions that commonly overlap.

Don't get stuck on different specific diagnoses, the spectrum can be understood as going all the way from fully NT to severe autistic, and evaluations have a big margin of error since it's all quite rough estimations (no matter of its tests or interviews) on where you fall on different scales.

Doesn't include fully NT. Edited to add https://neuroclastic.com/its-a-spectrum-doesnt-mean-what-you-think/ It really helps to explain what the spectrum means.

Yeah, but that is like two separate dimensions. Autistic traits are also spread according to a normal statistical distribution in the general population (from "more to less"), so both ways to visualize a spectrum are correct depending on what you want to discuss/communicate, even if the one in the article is what is typically meant.

A person can for example absolutely have some very real traits that effects his/her daily life, like trouble with sensory inputs, to tolerate sudden changes, have trouble understanding non verbal communication or emotions, while still in a correctly done evaluation not be "autistic enough" to meet criterias for a formal diagnosis. Then I think it's valid to describe it as having autistic traits.

That's basically what the article says, one or two autistic traits does not equal autism, to be diagnosed you have to be affected in most or all areas to some degree. But they also point out that not everyone is 'a little autistic'. Not saying that's what you said, but I've heard many people say that when they make a social blunder or something like that. Anyway, I think we're saying the same thing but from two different perspectives.

Yeah, then we seem to agree with each other. :)
