According to Banfield—no. As was noted on the American Enterprise Institute Blog this past year,
Banfield turned upside down the commonplace notion that wonks were politically neutral problem-solvers. Rather, he wrote, wonks tend to contribute problems not solutions to the political process. From their perches in academia and the upper echelons of government, social scientists and policy analysts identify “problems” in need of government attention.
