Brave or foolish?
John R. Lott, economist and senior research scientist at the University of Maryland is a brave man. In 2001 he published a study that concluded that legalized abortion increased murder rates from 1/2 to 7%. This refuted the study by the authors of Freakonomics.
According to this article in Cybercast News Service, the Economist magazine tells of two Federal Reserve Bank of Boston economists who said the Freakonomics study was error-filled and went on to say, "To be politically incorrect is one thing; to be simply incorrect, quite another." . . .
