If humans are unwilling and unable to rise over their mental constraints – one has to sympathize with them as they had very little experience with it. It appears that societal utility could be enhanced by segregation in transition, something that may extend over a century. A recent study shows that humans tend to segregate when the space occupied – say in a city – hits a threshold level. This indicates that a hard wired need to segregate exists in every one of the currently existing 7.2 billion specimens. Countries provide an efficient segregation scheme and for half the word’s population, the problem reduces to regional schemes – language, imperceptible shades of skin color, height and food. In any case, the need to segregate is as fundamental as the human itself.
Although it may be alarming for some to consider, it is possible that segregation is utility maximizing in transition to a higher level society. The planet, a sitting duck in the midst of space debris, may need to consider local and temporal maximization of utility – and segregation could be a dominant policy choice to maximize societal value.
