Michael Shermer’s September column in Scientific American is on Lott’s lawsuit. He got some comments from both Lott and Levitt:
I asked Levitt what he meant by “replicate.” He replied: “I used the term in the same way that most scientists do–substantiate results.” Substantiate, not duplicate. Did he mean to imply that Lott falsified his results? “No, I did not.” In fact, others have accused Lott of falsifying his data, so I asked Lott why he is suing Levitt. “Having some virtually unheard-of people making allegations on the Internet is one thing,” Lott declared. “Having claims made in a book published by an economics professor and printed by a reputable book publisher, already with sales exceeding a million copies, is something entirely different. In addition, Levitt is well known, and his claims unfortunately carry some weight. I have had numerous people ask me after reading Freakonomics whether it is really true that others have been unable to replicate my research.”
