It also wouldn’t work, nor would it likely trigger his delusions any more than not doing it. My understanding is that fundamentally, schizophrenia is when someone’s running internal monologue gets cross wired and confused with external input. Your stray random thoughts gain as much, or more, validity as actual events that you can see, hear, taste, touch, etc. Sane people know they have imaginations and random BS thoughts, and we have the ability to distinguish those from reality… but even so, sane people can be disturbed by their own random thoughts too. Now imagine if you physically COULDN’T distinguish them, or even a subset of them.

Adding additional external inputs isn’t going to do jack shit when the problem is actually the internal inputs. Not unless your external inputs are really able to make him start thinking, and thus generate more internal thoughts.
