Why Are Economists So Bad at Forecasting?

“Forecasts satisfy a deep psychological need that we live in a somewhat predictable and controllable world,” says Philip Tetlock, a professor of organizational behavior at the Haas School of Business at the University of California, Berkeley. “Those are essential stories. People just find the truth” — that the future is unknowable — “too dissonant.”

Most economic forecasts are worth less than the paper they are printed on but fill a need for investors and policy wonks who need “data” to “make a decision” or spin an agenda.

As this article from TIME points out there are too many moving parts in world economics to project forward data points with any degree of accuracy on a consistent basis.

Use economic forecasts as input for your investment decisions at your peril.
