How about lack of metal use in North America? Is that low intelligence too?
They knew about metal, they had native copper that was traded all the way from Canada to South America. But why go through all the work to build a foundry, smelt metal, and forge metal when it wasn’t needed?
No matter where you are you can reach down and find a rock that is workable into a very sharp and capable tool for the task in just half an hour.
Which is actually more intelligent? All the trouble of foundry infrastructure? Or just a few minutes created from a common material laying EVERYWHERE at your feet already? To this day the sharpest scalpels used for less scaring are still made of stone. They are sharper than any metal blades known.
Logical and rational practicality is NOT lack of intelligence.
Absolutely.
Working with what you have to do the best you can is survival at it's best.
Some are happy with what they have to work with, and do well, and do not care to push the limits any further.
Personally, I am happy my ancesters were not satisfied with what they had, and looked for better ways to do stuff.
Stone blades and tools were quickly abandoned.
For those made of steel and iron as soon as the “natives” could get them.
If stone tools were so superior why did they go away.

I believe you are mistaken.
The Aztecs smelted metal, and were on the edge of figuring out bronze.
The Incas knew about bronze, and used it for a few things.
There are many places where rocks suitable to take an edge are difficult to find. Flint and obsidian mines existed in both the old and new world. Good quality rock was traded long distances.
Technology and intelligence are not the same and should not be confused. From my study, people had to be smart and capable to survive with the lower levels of technology.
