As it stands, I have a hunch that the people at the top of governments tend to be among the more highly intelligent. I'll even give that to our leaders, but also to the leader of Iran, etc. If nothing else, the intelligence required to reach that level and stay there without getting killed or purged is impressive.

By and large, the countries that are run by a single, centralized intelligence, are worse off than the countries that are run by the distributed intelligence of the people, even if the average intelligence is lower.

My prediction is that the liberal democracies will fare better.
