“Human beings exist as individuals and as members of groups at all times. I am one and I am one of many… always. This also creates some inherent conflicts of interest. When we make decisions, we must weigh the benefits to us personally against the benefits to our tribe or collective. Quite often, what’s good for one is not necessarily good for the other. Working exclusively to advance ourselves may hurt the group, while working exclusively to advance the group may come at a cost to us as individuals.”
