One of the most dangerous errors of our time is the belief that human beings are uniquely violent animals, barely restrained from committing atrocities on each other by the constraints of ethics, religion, and the state.
It may seem odd to some to dispute this, given the apparently ceaseless flow of atrocity reports from Bosnia, Somalia, Lebanon and Los Angeles that we suffer every day. But, in fact, a very little study of animal ethology (and some application of ethological methods to human behavior) suffices to show the unbiased mind that human beings are not especially violent animals.
Desmond Morris, in his fascinating book Manwatching, for example, shows that the instinctive fighting style of human beings seems to be rather carefully optimized to keep us from injuring one another. Films of street scuffles show that “instinctive” fighting consists largely of shoving and overhand blows to the head/shoulders/ribcage area.
It is remarkably difficult to seriously injure a human being this way; the preferred target areas are mostly bone, and the instinctive striking style delivers rather little force for given effort. It is enlightening to compare this fumbling behavior to the focussed soft-tissue strike of a martial artist, who (having learned to override instinct) can easily kill with one blow.
It is also a fact, well-known to military planners, that somewhere around 70% of troops in their first combat-fire situation find themselves frozen, unable to trigger lethal weapons at a live enemy. It takes training and intense re-socialization to make soldiers out of raw recruits. And it is a notable point, to which we shall return later, that said socialization has to concentrate on getting a trainee to obey orders and identify with the group. (Major David Pierson of the U.S. Army wrote an illuminating essay on this topic in the June 1999 Military Review).
Criminal violence is strongly correlated with overcrowding and stress, conditions that any biologist knows...
