Boxes, arrows and insights

I have a habit of reading economics blogs. I'm not sure why, but I think it's because its a filed that grew up at about the same time that GG did, it has a technical side, and I'm friends with some economists. At any rate, here is a post by someone I have enjoyed for a long time. He's not an economist, but a finance guy from the City who went under the handle D-squared. Aside from making me laugh, the post also captured how I feel when I go to lots of psych talks (including many psycho-ling talks). Boxes and arrows, boxes and arrows: each connected to each several times over.
