> And sometimes it is better to have a truly random decision than to continue to follow the predictable inclinations of one’s established prejudices. Surely, the enemy will not be able to predict a shaman’s completely random decision.

Our individual brains do this too.

Belief grabs hold of one viewpoint, because it looks like the best for a moment, because things will go better for us if agree with our group, because it makes us feel better, because we want other people to believe it for our own reasons, because we are too tired to care, ...

Then it discards future alternatives, saving wasted cognition rethinking over and over.

Our brains don't care what the truth is, they care that we operate well. And there are so many good reasons to believe something that isn't true.

Many people have a hard time grasping that their feelings of overwhelming certainty, have virtually nothing to do with actual certainty. And that is the way our DNA builds us!

Constantly integrating new idea's is costly. Fatiguing. Ideology is so cognitively efficient. And our certainty feels so good!
