I think you hit the nail on the head with your comment on emotional intelligence and communication. That said, does the ability to empathize and communicate with someone outside of that window mean that it doesn't exist? I know that when I go full speed with someone at my level, it sounds like a foreign language to some of my peers. They understand the words we say, but they don't really understand the conclusions, implications, etc. Note that I am not sure I agree with the hard interpretation of the author of the article (specifically, "no meaningful communication is possible among people not sharing a common window of 30 IQ points"). That said, I do think that there are some fundamental differences in how people outside of a 30-point range perceive the world.
