An important point about IQ. It's postulated that as gaps between IQ grow, the ability to communicate effectively fades.

Average people can't understand someone with +3 SDs easily, and those high intelligence people cannot figure out how to speak to normies in a way that actually gets through to them.

But the same is true on the other end of the curve.

In this case, an average IQ in the 70s means that roughly 60% of jeets and negroids literally do not hear when actual people speak. They just hear "womp womp womp womp" like when the Peanuts kids talk to grown ups.

And for reference, a labrador has an IQ of about 40. Many of these, ahem, unfortunate groups, are closer to actual animals than to people.
