Defining dysfunction

This paragraph from a recent Paul Krugman post reminded me of something I've been meaning to dig into for a while.

A brief aside: I don’t think it’s right to call this a case of Washington “dysfunction”. Dysfunction is when we get outcomes nobody wants, or fail to do things everyone wants done, because there doesn’t seem to be any way to package the politics. In this case, however, people who oppose TPP voted down key enabling measures — that is, they got what they wanted. Calling this “dysfunction” presumes that this deal is a good idea — and that kind of presumption is precisely what got successfully challenged yesterday.

We hear “dysfunction” thrown around a lot (often by me), so it might be a good idea to pin down some definitions. Krugman is definitely on the right track, but statements about “nobody” and “everybody” are obviously unrealistic. Every scenario makes somebody happy, up to and including the rise of Cthulhu and his dark, chthonic host. A workable definition will have to take that into account, as well as considering differing intensities of opinion.

A system is dysfunctional if there is no consistent weighting of preferences that corresponds to its actions. (I'm going to be careful not to let this drift into a discussion of voting paradoxes because a good portion of this audience knows a great deal about the subject and I would have to do serious research to make sure I didn't make a fool of myself.)

For example, a group could do what the plurality wants, or it could use some sort of weight by rank (first choice is worth five points, second is worth four...), or it could take into account strongly held positive or negative opinions.

Let's use restaurants. A group might go to an Armenian place because three out of seven listed it as their first choice, or they could go to Chipotle because six people listed that as their second choice, or they could take Chipotle off the list because one person refused to go (I'm with that guy. Living in LA and going to Chipotle is like living in Rome and going to Pizza Hut). All of these decisions are consistent with a functional organization.

If, on the other hand, the group ends up going for Thai when everyone would have preferred burgers, that's dysfunctional. I can’t think of a reasonable and consistent weighting scheme that can produce that result.

A political party is more complex than a group of friends, but in some ways it may not be that much more complex. I’ll try to flesh this out later, but for now, while you have to be careful talking about what a large group “wants,” I suspect that there are a lot choices that the GOP would “like” to make (infrastructure spending, for instance) in the same sense that those friends would “like” to be having burgers now.

Based on these definitions, for large chunks of the Twentieth Century, I'd say that the Democratic Party was the more dysfunctional. The Republicans, however, do seem to be making up for lost time.

Reading over this, it's pretty clear that I have a ways to go before I have a proposal for something coherent and measurable and usable, but I do believe there is something out there, What's more, I suspect that, in 2015, it's probably more important to worry about dysfunction than about ideological extremism.
