Yeah, it's not like Arrow bothered with difficult math.

<Takes a micro class>

Oh. Oh crap.

<Teaches graduate micro class>

Oh. Right, "difficult" != "fancy." Difficult is the stuff of research, from qualitative methods to quantitative methods to formal theory. Fancy is a pejorative for lazy people if they equate it with "difficult." Now study for your comps.

The likelihood you teach a graduate micro class is exactly zero, since you didn't get that the reference is to Arrow's work on general equilibrium theory, which does in fact require advanced math. Y'know, that thing he won the Nobel Prize for? And no, Condorcet does not prove Arrow's Theorem, which is why he needed dozens of pages of dense math to prove it.

Maybe if you understood formal theory, you could have figured out why it's not a good choice to spout off about subjects you know nothing about.
