Errors in More Guns, Less Crime

Natalie Solent is disappointed in Lott, but is still impressed by More Guns, Less Crime. Unfortunately, the 98% figure is not an aberration. It is typical of the remarkable carelessness with facts that Lott displays and his refusal to back down even when obviously in the wrong. For more examples, see here and here.

Steve Verdon has responded to my critique of More Guns, Less Crime. Verdon starts by claiming that Lott's argument doesn't depend on their being more guns or less crime. He argues that you just need "more people carrying (concealed) existing guns legally" and that Lott found a…
Howard Nemerov has a post defending Lott and responding to Chris Mooney's Mother Jones article. Unfortunately, he gets his facts wrong, leaves out inconvenient facts and indulges in fallacious arguments. I'll go through his post and correct these, but first some general comments. Even…
