I think the problem with those who seem to advocate the "broken brain" idea is that they appear to think that brain brokenness is the origin of the problem, and that the interpersonal experience of a person plays no part in how the trouble began. In fact, I think people who promote this idea are denying that relations-between-people is a causative factor.

One of the clearest examples of this, I think, is E. Fuller Torrey. He is so set against the idea that how people get treated has nothing to do with "serious mental illness" that he has come up with the idea that it must be due to cat viruses. Now, since there are a lot of people also in denial, he has a certain amount of support for his approach. After all, looking at cat viruses statistically does not require one to look into one's own mental processes. That might be really scary!

How can we prove that cat viruses are not the culprits?
