Romer said he hopes at least to have set an example, for younger economists, of how scientific inquiry should proceed — on Enlightenment lines. No authority-figures should command automatic deference, or be placed above criticism, and voices from outside the like-minded group shouldn’t be ignored. He worries that those principles are at risk, well beyond his own field … And at the deepest level, he thinks it’s a misunderstanding of science that has sent so many economists down the wrong track. “Essentially, their belief was that math could tell you the deep secrets of the universe,” he said.
