Absent unusual cases such as traumatic brain injury, there is no clear dividing line between “human who is concentrating” and “human who isn’t concentrating”. A normal human can switch back and forth between these states with no warning, either for well-motivated reasons (“wait, that doesn’t make sense”/”bored now”) or for essentially none. So I think “humans who aren’t concentrating” is about transitory state, and “is/isn’t a general intelligence” is about overall capacity; any equating between those two sides is a category error.
