There is no totally wrong diagnosis in psychiatry. There are behaviors and experiences that fall info clusters. The Medical model wants to treat these clusters as it they were diseases like chicken los or heart disease. But the psyche cannot be seen. It is not clear that the brain is ever soley at fault in mental illness. Its not a matter or consensus that psychiatric conditions are illnesses. The whole ill.esa model is somewhat platonic. There is a perfect ideal person who enjoys sound mental health and deviations from the ideal form are bad or wrong. Its just not so.

The whole illness vs injury distinction is as silly as race or gender categories.

We cluster symptoms for the Same reason we cluster traits in animals. Nature makes no distinction between canines and felines. Cats and dogs dont. Make that distinction. We do. Its what we do. To organise our world we make categories. Then we believe they are real. Go figure.

Symptom clusters are a tool. Thats all they are.
