More Laing-Think About It. Cool.

But as Laing was, moreover, a critic of psychiatric diagnosis, he argued that diagnosis of a mental disorder contradicted accepted medical procedure: diagnosis was made on the basis of behavior or conduct, and examination and ancillary tests that traditionally precede diagnosis of viable pathologies like broken bones or pneumonia occurred after (if at all) the diagnosis of mental disorder. Hence, psychiatry was founded on a false epistemology: illness diagnosed by conduct but treated biologically.

The fact that medical doctors had annexed mental disorders did not mean they were practicing medicine; hence, the popular term "medical model of mental illness" is oxymoronic, since, according to Laing, diagnosis of mental illness did not follow the traditional medical model. The notion that biological psychiatry is a real science or a genuine branch of medicine has been challenged by other critics as well.
