It’s about data and smugness.

In practice, I don’t know that mainstream economists really care that much about the “ends” side of things. For instance, when they talk about “demand,” they aren’t talking about how many people actually want something or how badly they want it. For these guys, “demand” is the quantity of a commodity that people are willing and able to pay for, at a given market price. If ten thousand people in a wasteland are dying of thirst, and they have no money and no way of getting any money, what’s the “demand” for a sip of water in this particular market? It’s zero.

I’m talking about mainstream economics here. Since the so-called marginalist revolution at the end of the nineteenth century, the discipline has tended to ignore idle speculation about why we value this or that. There are exceptions, like hedonic shadow pricing, or research on entrepreneurship, or maybe some market design stuff. But mostly we’re just too weird and ornery. And besides, everybody’s different! Friedrich von Hayek is the big cheerleader for this perspective. And that shift was part of a bigger shift whereby mainstream economics became increasingly mathematical and “scientific.” The word “science” appears in Robbins’s definition, for instance. Much of the discipline, some would argue, also became increasingly less grounded in reality.

By contrast, science fiction — and other kinds of literature — is obviously extremely interested in getting inside people’s heads and hearts, and figuring out not only what people desire, but also why and how, and what it feels like. And how desires might change. And the deeper significance of those changes. When you write a novel, you’re not going to start off saying, “Okay, I am going to assume that my characters preferences will remain fixed.” So maybe that’s one reason the meeting between science fiction and economics can be quite fruitful. Science fiction has the same love for abstraction and modelmaking, and shares a certain sense of what “rigor” is … but it’s fundamentally about actual human experience in a way mainstream economics just isn’t.

The inestimable (and brilliant, and loquacious) Jo Lindsay Walton, interviewed on the intersection of economics and science fiction by Rick Liebling for The Adjacent Possible; a long read, but full of gems.

The above recapitulates, albeit in JLW’s own style, the argument I’ve been making for narrative prototyping in my own academic work: a model must be exposed to the social dimensions which it has necessarily externalised. Human behaviour is inherently unquantifiable — and indeed, the more we attempt to quantify it (and “manage” it on that basis), the more inhumane the results become.

What applies to economics applies equally to infrastructures; it’s wicked problems all the way down, and solutionism is a wicked problem in and of itself (as Keller Easterling also appears to be arguing). Until we understand the role of desire — in the DeleuzoGuattarean sense, but also to some extent in the weaponised-behavioural-psychology-AKA-marketing sense — in sociotechnical change, we will achieve nothing but an accelerating accretion of “solutions” which turn out to be new and intractable problems in their own right.

(See also Tainter on increasing complexity as a strategy for addressing problems arising from existing complexity; to paraphrase very broadly, it works, but it works ever less effectively every time, and only until it no longer works, at which point you’re wandering around the ruins of your civilisation wondering where it all went wrong.)
