Expertise and punditry (updated)

I concluded my post “Against Epistocracy” with the question “Who gets to decide who is well-informed? And who gets to decide who gets to decide?”. This is, I think, a fatal flaw in any system proposing to replacing democracy with rule by a well-informed elite, or any kind of putative aristocracy. But even in a democratic system, we have to make decisions about who should decide things. In many cases, we would like to call on expert advice, and that brings us back to the question “who, if anybody, is an expert on a given topic”. I don’t have a complete answer, but I think it’s helpful to distinguish between experts and pundits or, better, between expertise and punditry.

Update: I just saw this review of The Death of Expertise: The Campaign Against Established Knowledge and Why it Matters by Tom Nichols which is obviously relevant. A crucial requirement for a successful defence of expertise is that we avoid defending authority based on mere punditry.

Murray-Darling Plan Doomed to Fail

That’s the conclusion of a recent depressing report from the Wentworth Group. There is, of course, an “unless”, but having spent decades of my professional life on this issue, I can’t say I’m hopeful. Certainly, there’ll be no progress under the current government, as this issue is now part of the culture wars. Whether Labor will do any better, I don’t know. Here’s the comment I provided to the Australian Science Media Centre.

The depressing outcomes reported by the Wentworth Group are the inevitable result of the policy decision to abandon buybacks, that is, the voluntary purchase of water entitlements from irrigators who are willing to sell those entitlements. Buybacks are by far the most cost-effective method of securing additional water for the environment as well as providing a direct benefit to farmers, who can use the proceeds to reinvest in dryland agriculture or to assist a transition out of agriculture. The abandonment of buybacks, combine with a failure to address the needs of irrigation-focused communities in the Basin represents the worst of all policy worlds.
