Probably not true about all ND traits, but many are things that exist in most people and are either magnified or muted in ND people.
I’ve never been diagnosed ND; though I had a psychologist suggest I might have Asperger’s at one point back when that was the language used, it was never followed up on. So maybe I’m ND? But I wouldn’t claim to be.
But no two people are neurally identical. Saying that someone is neurodivergent essentially has to mean that they’re far enough from the baseline/average to qualify as such.
I know there are specific diagnostic criteria, but those are largely based on determining how different someone is from typical and how it affects them. But almost every trait that is present with autism is present in neurotypical people as well, just to a different degree.
That’s not a universal statement or anything, just a vague generalization.
