Panpsychism is not outside the realm of the scientific method. In fact the first thing a scientist should research is the validity of their perceptions because if they are unreliable, all other observations are unreliable. <br><br>The way to test it is by discovering how consistent and “real” a hallucination can be. The best, most consistent hallucination we know our minds can produce that is not reality is lucid dreaming. It is really surprising there is so little research on it.  I don’t know of a subject in science that deserves more attention than this and I firmly believe there are great discoveries about the nature of consciousness to be made on that frontier.
