Yeah idk how they even measure that sort of thing and I’m skeptical as well, that’s just the numbers floating around. I wonder too if it’s tied to literacy in any way.

Though I suppose there are different ways for brains to work than just verbally. Some people’s brains turn sounds into colors (perfect pitch), some brains don’t have visual memory (aphantasia), and others supposedly have photographic memory. So who knows how this all actually shakes out.
