Gap filling with flawed perceptions is evolutionary. The antelope on the African plane does not always have time to assess if the swaying grass is wind or a lion stalking them. We often, far too often fill in gaps with flawed perceptions because that placebo can create safety in numbers in a group dynamic. The Ancient Egyptians were successful for 3,000 years because of their false belief that the sun was a thinking being.
Placebos do work in evolution, because evolution is only about reproduction, not fact finding.
