If our brains are descended from ancestors whose brains tended towards groupish ritual that would explain a lot about our world.
Yes it would. Anglican funerals are a good example. It may be just high church but the vicar was dressed in bright green robes and walked in saying at the top of his voice 'I am the resurrection and the light'. I nearly jumped out of my skin because of course we didn't see him enter as all the pews faced the front. Then the whole church reciting the Lord's Prayer. Creepy!
I wonder what evolutionary blip has caused some of us to hate groupish ritual. Is it because we were raised JW with its lack of ritual or are people attracted to the new religions because they dislike group ritual. Personally I hated the Memorial, the only groupish ritual we had. Although I suppose you could class singing together as a group ritual. I quite enjoyed that especially at conventions. Now people join and sing in choirs without religion, I see them advertised on town notice boards. We still want to do things in groups even without religion.
