Why would anyone think that economists, as such, have evaluative expertise? Where would they get it: in a graduate seminar? If so, which one? The fact is, economists are as diverse in their values as any randomly selected group of individuals. The same is true of philosophers. What economists and philosophers have is technical expertise. Economists can tell policymakers what it costs to get this or that bundle of goods; they cannot tell policymakers which bundle of goods to choose. Philosophers can tell people what it costs to believe this or that; they cannot tell people what to believe. The only leverage an economist has is the law of supply and demand. The only leverage a philosopher has is the law of noncontradiction.
