I would say, it is the capability of coming together to common knowledge and common values in any decisions involving more than 150 people. That’s the number. As humans, we cannot reliably track the theory of mind, what is going on in other people’s mind, when there are more than 150 people over a long term, which is why juries and so on are always selected to be smaller groups of people, because you cannot get consensus when the room is 1000 people. On the other hand, there are deliberative or facilitation skills that use like smaller rounds and then larger rounds and then larger rounds to achieve a compression of consensus.
