Except… it doesn’t? The study would need to be replicated to merely strongly suggest that the proposed procedure would ameliorate social deficits. No further inferences may be made beyond the scope of the study. It simply suggests that these chambers may treat one negative facet of autism, nothing more. It may provide a potential research direction, but it has been repeatedly shown that autism - like many areas of neurodivergence - is highly polymorphic in cause, manifestation, and other characteristics. I’d go further and say the study doesn’t even suggest brain damage, if I’m being honest. That would have to be studied on its own.
