I watched a documentary about bees (I think it was a "Nova Science Now" segment). A guy set up a bee colony on an island. The bees were going to need a new hive, so he set up 2 possible locations nearby, one was deliberately made to be better than the other. Bee scouts went out looking for a new location, some found the good hive, others the less good hive and came back to tell the colony. They communicate by pointing and shaking their bodies. The bees who found the good colony were more vigorous. Also, when scouts for one location encountered scouts from the other, telling the hive to go to the other place, they would try to suppress them. Eventually the colony made a decision to go to the better location. But the comment was made that this was very similar to how neurons stimulate and suppress each other to reach a decision in an individual brain. so it's a kind of neural network.
After watching the documentary, I was struck by the idea that this is how a human society ought to work. Different people from different walks of life and temperament debating each other, disagreeing with and maybe trying to suppress those they disagree with. But in a healthy society nobody gets to dominate! When some faction gets the upper hand too much, everything goes bad.
Anyway, I think the neural network model is better than the 'rational' one. I've read where sometimes artificial neural networks design stuff better than usual logical engineering methods, and nobody can figure out why they work so well. Human society might be like that.
