You were rebellious. From the point of view of a common teacher, that means you are not innocent. There is actually a old common saying, when some kid got a beaten, but it later turned out to be not guilty of that ... "well, he deserved it anyway" or "well, then the beating was in advance for something he is about to do" "or some other hidden sin", instead of a apology.
Which means self fulfilling prophecy. Punishing someome for something they didn't do - and for sure there will be reasons later on for things they will have done.
There are still way too many teachers and alike, who think a childs free spirit needs to be broken first, before they can learn something useful.
It is!
But you don't need to break someone, to help them learn it. Breaking people is just the cheapest method.
For instance, it'd be incredibly unfair for me to accuse you of being a jackass for a comment like this, when I know nothing about you... it'd also be equally unfair for me to assume you're an authoritarian... because I don't know anything about you, and therefore have no reason to make such an assumption.
Sort of like the teachers in the prior comments.
I'm not on the spectrum, but I was a rebellious kid who didn't like to take shit from teachers. My defiant and sarcastic reactions to accusations were often considered evidence that I'd done wrong when I was innocent.
It's not that lie-spotting heuristics work better for neurotypical people or worse for people on the spectrum. They don't work at all for anyone. We're all in the same boat.
