In primitive society, a being curious would dobt it would be useful. But once you've established a way of surviving ritand i'm not stoken by an evolutionary dens bu a in our lives, then the need for curiosity kind of decreases. An incurious person can be perfectly polite, but there isn't really much hunger toto learn anything they don't know already. So i'v just wondered, e, you know, how to people end that way?
