Tom Spencer on David Gross

Tom Spencer thinks that the latest information on David Gross might be the straw that breaks the camel’s back.

The Minneapolis Star Tribune has a story about David Gross, who, after all this time, is the only witness to Lott’s 1997 survey who has ever been found: A major player and legal consultant on Minnesota’s new gun-permit law is a former board member of the National Rifle Association who was fired from the Minneapolis…

David Glenn’s article on academic blogging in the Chronicle of Higher Education mentions the role of blogs in the investigation of Lott’s conduct. William Sjostrom writes “Lott always releases his data.” But Lott has not released the data for his 1997 survey.

Donald Kennedy, Editor-in-Chief of Science has an editorial (subscription required) in the April 18 edition entitled “Research Fraud and Public Policy”. Here is some of it: Michael Bellesiles, of Emory University, supported the gun control case with a book called Arming America. Part of his argument was that guns were rare at much earlier times…

Whether it is possible depends upon how finely you do the weighting. If you do something as simple as…

Lott’s bogus weighting scheme

Last September Lott told Lindgren that he “weighted his respondents by demographic information taken from his main national study in More Guns, Less Crime” On January 14 he provided more details: I did not weight the sample by household size but used the state level age, race, and sex data that I had used in…

Otis Dudley Duncan has written an excellent article on Lott and defensive gun use surveys. I’ll quote from the conclusion, but you really should read the whole thing: Investigators are obliged to tell the truth about what they take from the work of other investigators and to provide verifiable evidence and complete documentation for statements…

After I concluded yesterday that Kopel had probably added the attribution to Kleck in one Lott op-ed, Lott has weighed in, contradicting Kopel’s story. In this posting Lott writes: “My vague recollection of what happened is that David Kopel (Research Director at the Independence Institute) called me up asking for more information on who had…
