I think that psychosis can be characterised as a failure of inner alignment.
Let me explain with two examples.
We all seek status, but we obviously don’t have a genetically hardwired status classifier in the brainstem. Instead the rest of the brain figures out what our social status is. When something boosts our estimated status the ventral tegmental area in the brainstem sends out a dopamine reward signal. If the brain’s inner alignment mechanisms fail then the rest of the brain maximises its dopamine reward by convincing itself that it is the messiah.
The parts of the brain which detect threats get rewarded whenever they detect a threat so that they have an incentive to be vigilant to threats. If inner alignment fails then the threat detector circuits try to maximise their dopamine reward by hallucinating ghosts or snakes or whatever.
Many antipsychotics are dopamine antagonists. Dopamine antagonists don’t fix the underlying alignment failure but they trade off less psychosis for more apathy.
