I have been wondering about how some geniuses have had psychosis and how the psychosis relates to the genius. A genius is someone who creates something that that solves a profound problem and greatly improves the wellbeing of a society, like mathematician John Nash solved those Nazi encryption codes.
As for how the brain patterns translate into conscious thought, Elyn Saks, a mental health law professor at the University of Southern California, explained that people with psychosis don’t filter stimuli as well as other people. Instead, they’re able to entertain contradictory ideas simultaneously, and become aware of loose associations that most people’s unconscious brains wouldn’t consider worthy of sending to the surface of our consciousness. While the invasion of nonsense into conscious thought can be overwhelming and disruptive, “it can be quite creative, too,” said Saks, who developed schizophrenia as a young adult.
Throughout our daily lives we experience an influx of emotions, sensations, and sounds. If we had to consciously decide at all times what to ignore and what to pay attention to, we would quickly become overstimulated. This ability to screen things out of awareness that were previously tagged as irrelevant is called latent inhibition. Latent inhibition has a strong biological basis and operates automatically to filter out information. Those high in latent inhibition are very good at this inhibition. Those with a reduced latent inhibition have a difficult time with this form of inhibition. Reduced latent inhibition has been associated with schizophrenia as well as a predisposition to psychosis.
