I know this is supposed to be a fun question, but there is a serious and interesting issue underneath it, and I only mention it, because it’s my particular obsession.
Viz: how do humans categorize? Clearly the simplest categorization scheme is binary. Us/Not Us (on whatever variable we are measuring ourselves).
The impulse to use the us/not-us categorization scheme is very basic, I think. It’s the simplest scheme. It does not require any sophisticated discrimination.
We could, of course, place people on a spectrum—how much do you like Neil Diamond? How strict is your diet? And the Myers-Briggs is also a vast simplification, even with sixteen categories.
However, it is said (but I don’t know by whom) that humans can generally keep, at most, seven categories of things in mind at any one time. Some of course, can do nine, and others can only think binarily.
I think that’s why we make fun of binary categories: it’s clearly so simplistic. Hmmm. Should we figure out how strong a Neil Diamond fan a person is by counting concerts they’ve been to, and recordings they own? Now that’s my idea of fun!
