We know that autistics have deficits in interpreting facial expression, but now we also know that, as predicted by the diametric model, people with schizotypal traits do the opposite and exaggerate facial expression.
The diametric model suggests that psychology is divided up into folk and scientific, popular and official sub-types, with popular psychology being superior in some respects to its official counterpart.
The unexpected finding that protection against schizophrenia is conferred by congenital cortical but not peripheral blindness gives credence to the diametric model’s claim that hyper-mentalism is the core pathology in psychosis.
A study directly comparing autism and schizophrenia risks in a population of 5 million provides the first large-scale empirical test for the imprinted brain theory’s prediction that such risks co-vary inversely.
