>>11329084Most indigenous African languages lack several types of words otherwise found in other cultures.
Gradient for example, is a concept wholly lacking. If someone wanted to say specifically how high fruit is up on a tree, they would have to do it in french. Otherwise, the fruit is at the top, or the bottom. Most african languages suffer in this way.
This information is taken from another post by an anon who visited Africa, noticed this trend, and followed up on it with calls to african-studies professors at various universities. I don't have the screenshot, sorry.
All this being said, I can only imagine that is someone from another culture, say Norway, were raised exclusively in an indigenous African linguistic environment, they would be severely lacking in verbal intelligence and it's associated correlation to g, by the time they fully developed.
tl;dr: yes.
