There are four kinds of people, those that put things into categories, and those that like matrices.

There's at least two meanings for stupid. One is someone who is not intelligent, and it's just kind of an intrinsic thing. The other is someone who does something stupid, irrespective of their intelligence. This is a conditional attribute that depends on available information / motivation / laziness.

Point being a 2x2 matrix is just an oversimplification of real life and also wtf are the axes here???
