GETTING THE MODEL RIGHT. The dean at Anonymous Community sends some traffic my way in the course of reacting to David Frum. There will be some reactions to his reaction here in due course. One theme that will appear is whether higher education is human capital or a signal, something that's been a topic for a long time, starting with two posts in November 2002 with another long post in December 2004 and more in September 2006 and a complication two years ago. Study those now. They will be material for a lesson this weekend.
