From Russ Roberts on the latest EconTalk podcast:
… this is really embarrassing as a professional economist — but I’ve come to believe that there may be no examples … of where a sophisticated multivariate econometric analysis … where important policy issues are at stake, has led to a consensus. Where somebody says: Well, I guess I was wrong. Where somebody on the other side of the issue says: Your analysis, you’ve got a significant coefficient there — I’m wrong. No. They always say: You left this out, you left that out. And they’re right, of course. And then they can redo the analysis and show that in fact — and so what that means is that the tools, instead of leading to certainty and improved knowledge about the usefulness of policy interventions, are merely window dressing for ideological biases that are pre-existing in the case of the researchers.
