Austrian economist Russ Roberts as George Mason writes in the WSJ:
"[T]he arsenal of the modern econometrician is vastly overrated as a diviner of truth. Nearly all economists accept the fundamental principles of microeconomics—that incentives matter, that trade creates prosperity—even if we disagree on the implications for public policy. But the business cycle and the ability to steer the economy out of recession may be beyond us.
The bottom line is that we should expect less of economists. Economics is a powerful tool, a lens for organizing one's thinking about the complexity of the world around us. That should be enough. We should be honest about what we know, what we don't know and what we may never know. Admitting that publicly is the first step toward respectability."
