some people would just develop a different persona for each group
That is possible but maybe only more likely if the groups are very clearly separate, such as when you are in a faraway country for a long time. But if you are e.g. in a multi-cultural city where there are many maybe even overlapping groups or where you can’t easily tell which group it is, it is more difficult to “overfit” and easier to learn a more general strategy. I think universal morality is something of the more general case of this.
Julian Jaynes would say that this is how human consciousness as we know it today has evolved.
Which makes me wonder, what would he say about the internet bubbles we have today. Did we perhaps already reach peak consciousness, and now the pendulum is swinging back? (Probably not, but it’s an interesting thought.)
