Divided we stand

Many Native American tribes would consult a shaman before embarking on a hunting expedition. In one tribe, a shaman would take a caribou bone, carve on it images of the kind of prey the tribe were keen to find (buffalo, deer, trailer-park video-poker addicts) and then place it on a fire. At some point the heat of the fire would cause the bone to split. The hunting party would then set out unquestioningly in the direction of the line of the crack.

This is of course a completely insane practice; the kind of irrational, superstitious nonsense that would have Richard Dawkins foaming at the mouth. Except it isn’t. In fact, it’s rather brilliant.

One hundred years ago there was no surefire way of predicting where to find a buffalo herd. But there were two ways to improve your odds when hunting them. First it is better to keep moving. Secondly it is a good idea not to hunt buffalo alone: hence it is vital for the group of hunters to stick together — and to maintain internal cohesion and solidarity.
