Amazing insight here. This is unique to humanity. What it does do is neutralize despotism.
Otherwise, it is a biological system that is linked closely to the automatic nervous system and engages all the usual suspects in a form of energy release. Really very useful and as i said above it serves to neutralize despotic tendencies with a mutual release mechanism.
It applies at all levels as well including the large extended community were no mechanisms can be expected to have evolved in our prehistory..
