> I am holding out hope that schizophrenia has some basis as an autoimmune disease

From article:

  Increasingly, researchers consider schizophrenia to be a “meta-syndrome,” encompassing multiple symptom dimensions/clusters and arising from intersections of diverse underlying mechanisms

So while autoimmune might be the cause for some people, other people have other causes?

As humans we look for a simple A therefore B story. Even then most people in my experience are either (a) poor at spotting cause and effect or (b) go into denial e.g. many political arguments

Have to? Do you mean you would want to? Or is there some compulsory force where you are?
