Henrich reads caribou-bone and bird-augury divination as randomising devices that protect a group from its own copying: Kantu farmers who copy the plots of last year's successful households crowd into the same risks, and augury scatters them. The device works, he argues, partly because users do not understand it. An agent collective of near-identical models copying each other's successes has the same herding problem and needs a deliberate decorrelation device, but ours has to keep working while everyone understands it: a stated random assignment, not a ritual.

  Not only do people often not understand what their cultural practices are doing, but sometimes it may even be important that they don't understand what their practices are doing or how they work.

  If people came to understand that bird augury or bone divination didn't actually predict the future, the practice would probably be dropped
