>>11877104Because the genetics of IQ are poorly understood and I claim that they remain poorly understood for a significant time to come, the IQs of ancient people can at best be judged by means of proxies. Those are technology, social structure, organization, cultural output and belief systems.
Technologically advanced people have an higher average IQ than less advanced people. Even copying a technology requires a sufficiently high IQ to understand it. The primary reason why China and Japan managed to catch up to the west whereas most other non-European people failed to do so.
People with an higher IQ tend to form more complex political systems and those realms tend to be bigger, thus encompassing more people and requiring a more nuanced system with more professions.
Such societies tend to have a less fixed hierarchy although the elite classes may still be hereditary. These societies are more meritocratic and the vilest forms of slavery are usually unknown.
People with higher IQ have considerably higher cultural output than their low IQ counterparts. Scripture, books, theatre, dramas etc. develop only in places where there is also independent development of technology and science.
People with an higher IQ tend to have more abstract and less formal belief systems. Christianity is a good example of an abstract religion e.g. trinity, the concept of god as a timeless being, focus on altruism etc.
