Human Action, not Human Experimentation

Apropos to Jonathan's recent post on global warming and the scientific method, Arnold Kling points to this piece on the Great Depression by Thomas Sowell. An excerpt:

Perhaps worse than any specific policy under FDR was the atmosphere of uncertainty generated by incessant new experiments. Billions of dollars of investment were needed to create millions of jobs for the unemployed. But investors were reluctant to risk their money while the rules of the game were constantly being changed in Washington, amid strident anti-business rhetoric.

People are not lab rats. We do not like to be experimented upon against our will. (Then again, neither do the lab rats, but that's a whole 'nother kettle of, um, fish.)
