I think a lot about the double sort of groupishness, rightnd what it tends to be is that groups can moderate you to be altruistic and to act in be selfless ways. But usually it is in the service of members of your own group. And so do think there are these crucial questions about, how can you build on the moderating force of a group et how can you built on? That's an incredibly hard question. So i'm speculating here, because you put me on the spot. One is obviously a minimum level of mutual trust, or at least an absence of mutual fear. Rit, this is only going to work if you don't have reason
