This is a straightforward consequence of the bias-variance tradeoff, autistic brains tend to get too much information which is mathematically indistinguishable from noise.
This is why many of the repetitive patterns, social blindness, strong habituation, meltdowns, shutdowns, isolation, etc, work, they are informationally-linked coping mechanisms.
It is weird to me how advanced in some areas we are and how pop sci or culturally narrative driven in others. These are some extraordinarily basic ideas from basic and moderate information theory, there are more but it is difficult for me to summarize well and distinctly.
Everyone go read Shannon, then Varley's info theory for complex system scientists. So many brain (and otherwise) phenomenons make sense and have strong predictive power for the complexity of the model, but that is sort of trivial since the brain does operate with informational dynamics by default.
