Famous schizophrenia researcher E. Fuller Torrey recently wrote a paper trying to cast doubt on whether schizophrenia is really genetic. His exact argument is complicated, but I feel like it sort of equivocates between \u201cthe studies showing that schizophrenia are genetic are wrong\u201d and \u201cthe studies are right, but in a philosophical sense we shouldn\u2019t describe it as \u2018mostly genetic\u2019\u201d.

Awais Aftab makes a clearer version of the philosophical argument. He\u2019s not especially interested in debating the studies. But he says that even if the studies are right and schizophrenia is 80% heritable, we shouldn\u2019t call it a genetic disease. He says:

Heritability is \u201cbiologically vacuous\u201d (Matthews & Turkheimer, 2022), and I think we would be better off if more of us hesitated to assert that schizophrenia is a \u201cgenetic disorder\u201d based predominantly on heritability estimates.

I think about questions like these through the lens of avoiding isolated demands for rigor. There are always complicated ways that any statement is false. So the question is never whether a statement is perfectly true in every sense. It\u2019s what happens when we treat it fairly, using the same normal criteria we use for everything else.
