Interesting, isn't it, how drawing gets itself marginalised. Andrew Hill makes the point nicely.

But perhaps it is that social scientists trade in words too much. Perhaps they tend to exclude drawings. I make this suggestion because engineers and scientists endlessly draw, sketch, and draft, when they are talking. There seems to be an essential visual component to such shop talk. Indeed, they joke about drawing on tablecloths in cafes over lunch (paper cloths are better than the real thing because you can tear off corners and take them back to the laboratory.) Then, of course, the visual turns up, too, in more formal modes, in the pages of scientific journals such as Nature. Though that isn't drawing any more.

So, anyway, here's another way of putting the question: why do we draw so little in the course of our social science talk? How did we get to be so exclusively verbal?
