Sober and Wilson Unto OthersIn each subgroup there is no discrimination against women; but in the total group women do less well. (Discussion question: does this constitute de facto discrimination against women?) Could something analogous happen in the competition between egoists and altruists: could it be that in each subgroup egoists do better, but in the total group the proportion of altruists remains stable? For example:Imagine that a population of 200, equally divided among altruists and egoists, is split into two equal sized groups, the tough group and the soft group. The tough group contains 90 egoists and10 altruists. As a result of the tough conditions, at the end of the breeding cycle the group has declined so that it only has 90 members, 85 egoists and 5 altruists (the egoists have done comparatively better). The soft group starts with 10 egoists and 90 altruists. As a result of the soft conditions, at the end of the cycle it has grown to contain 110 members, 15 egoists and 95 altruists (the egoists have again done comparatively better). The population still contains 100
