Overhead at WWS

Last week a classmate of mine at the Woodrow Wilson School shared this story, which I in turn share with permission.

Today G and I were doing our impossible econ problem set in Schultz Café. It was about consumer surplus so there were some nice geometric properties, and it was fun finding the areas of the triangles and trapezoids. I said out loud, "I don't how to do it the econ way, G. I only know how to do it the 9th-grade-math way."

Guess who was sitting right behind us?

Christopher Sims.

For background, search this article for the paragraph on Sims and the SAT. Maybe this is why economics folks might think we public policy students aren't so great at math? Related: how to fight impostor syndrome.
