Last year, as an incoming graduate student, I had to sit through a bunch of talks about my health insurance and, discomfortingly, the rules on dating undergrads. Anyways, one of the talks was by a vice-dean of something trying to encourage more interdisciplinary fraternization. But he asked us, which profession writes the most? Apparently, it's engineers, from all the paperwork, memos, and other communication.

I actually have no idea if that anecdote was true, but it does seem in-line with Latour's point.
