Experts shmexperts

Michael Greve has a nice discussion of how the economy and much of the government has been outsourced to panels of experts who are not particularly expert:
How is this working out? Not so well, in my judgment—not for the pubchoice reasons of old, but for more Hayekean reasons.
For starters, it’s obvious that the experts don’t have a clue. The Fed’s pronouncements anno 2007, to the effect that everything was firmly in hand, are the stuff of legend, and its models have proven lamentably inaccurate in predicting even short-term economic performance. As for the experts’ climate change models about the planet’s behavior a century hence, right.
Even so, expert government proceeds on an implied premise of omniscience. The intergovernmental committee that decides, under and pursuant to the Endangered Species Act, whether the One-Eyed Toad shall live or die is called, only semi-ironically, the “God Squad.” (That would have been a terrific title for IPAB, but it’s already taken.) The squad’s reasoned decision-making is one step up from shooting dice. We can live with that, even if the toad cannot. However, expert ignorance increases with the scale, scope, and complexity of the experts’ mandate; and when we’re taking about the U.S. economy or the planet, that’s biggish. Still, we’re supposed to believe that there’s nothing wrong with the attempt to predict and manage these systems—nothing, that is, that can’t be fixed by an econometrician in the Fed’s basement or perhaps the Mann Brothers’ Earth Band (Michael with the hockey stick and Manfred with the keyboards).
Hard to say, from where I sit, what’s worse: the dark suspicion that the experts may actually believe their own models, or the fact that they’re putting on a game face in public and, in so doing, impede a serious discussion over what the institutions can and cannot do.
