Seeking Correlation

It would be interesting to analyze how many reporters of sightings and/or encounters with the phenomenon are believers vs. non-believers that humanity is in the presence of other advanced intelligences. The idea being that we are looking for some validity to the theory that you have to be a believer to have a UAP sighting or encounter with its occupants. This belief could function as a sort of “precondition” to the phenomena displaying itself to the witness. Further, what is the spiritual inclination of the observer/experiencer? Are they more attuned? Or is distribution correlation completely random?
