@glyph In math, when analyzing metric spaces, I've heard this described as the "triangle property"
f(x,y) + f(y,z) ≥ f(x,z)
I am not sure exactly what the terminology would be, but I think of this as being the critical abstract algebra property that "utils" break. We expect
U(x) + U(y) ≥ U(x + y)
EG the utility we get from having X and Y at once is equal to the utility of X plus the utility of Y. Maybe more. But in fact they're uncorrelated. Could be less. Combining two +U things could be -U
