The evolution of punishment explained

Modern hunter-gatherer societies, which are assumed to be similar to those of early man, have a maximum size of 150-180 people. Without punishment, the computer simulations suggest that co-operation would have died out in groups of this size.

It is interesting to note that, in terms of this article, public schools are still operating at a pre-civilization level. But I already knew that.

Thanks, once again, to J. Orlin Grabbe.
