As a linguist and race realist, is there a correlation between language hardness and racial IQ?
There is no relationship at all between language difficulty and racial IQ. Amerindian languages are the most monstrous on Earth, and their IQ’s are only ~87. Eskimo languages are horrific, and Eskimos have ~91 IQ’s. The language of the Bushmen is insanely hard, but their IQ is thought to be between 50-60. Aborigine and Papuan languages can also be incredibly difficult, and their IQ’s are very low.
The languages of the Caucasus are the hardest on Earth, but their IQ’s are only ~85-90.
Truth is that as languages become used by industrialized societies as forms of mass communication, they tend to simplify and a lot of their difficulty works out of them. This is because people in modern advanced societies often want to get their point across as quickly as possible, whereas a hunter-gatherer in the Kalahari has all the time in the world.
In contrast, primitive people often have the most insanely complex languages. Primitive or noninudustrialized agrarian, rural or mountain-dwelling people do not have much intellectual stimulation, so they often play with their incredibly difficult languages as a source of creativity, fun and intellectual stimulation because they are intellectually starved and bored.
The more advanced the ethnic group -> the simpler the language.
The less advanced the ethnic group -> the more complex the language.
Of course there are many exceptions, and linguists tear their hair out and start screaming and yelling if they read what I just wrote, but I do think there is some truth to it.
