Non-dichotomous abstractions that fail to get a deep personal response from the reader don't make good reading (or at least publishable reading). On a positive note, like you said, at least it's suggesting there's more than one group: thanks to Mr. Zuckerberg and other Silicon Valley poster children, we assume that everyone peaks in their 18-25 range, so it's actually refreshing to be reminded of cases in the past where this wasn't true. Actually seriously addressing the issue and trying to find a complicated system of abstractions to describe it would be far to... academic. In my mind, that means "refreshingly deep", but I bet in most minds it means "booooooooooooooooring".
