I missed the party on interdisciplinary studies last week — see here for links — but it did raise a question that I don’t think was a focus of the discussion, namely, all else being equal, can interdisciplinary scholars teach law school classes just as well as “non-interdisciplinary” hires? If, as Brian Tamanaha claims, more schools are adopting interdisciplinary programs, presumably the character of their faculties will need to reflect that ambition — i.e., they will have to hire more professors who have spent relatively more time studying and relatively less time in practice. Indeed, that balance does not only pertain to schools going interdisciplinary. Larry Solum suggests that in 20 years, law schools might be taught by law Ph.D.’s, who will presumably have less practice experience than today’s non-Ph.D. law faculty. So the question is really one of scholarly credentials versus experience. Will law teaching be better, worse, or unaffected by such a shift, if it occurs?
I’m skeptical of arguments that quickly equate “different from how it is done now” (or, similarly, “different than how it was done when I was younger”) with “worse.” So that’s a danger to avoid. However, as someone who views himself as having both interdisciplinary interests and some practice experience, I feel unusually free of biases here. And at the end of the day, I lean toward “worse.”
