Many comments have been posted on this letter based upon the news story written on it in the Chronicle of Higher Education, but few have seen Levitt's actual correction letter. Levitt at least acknowledged that he sent multiple problematic "emails" over more than one day. Among those commenting on the original news stories please see Ted Frank, Ben Zycher, John Palmer, Craig Newmark, Robert Wallach, Clayton Cramer, Larry White, Steve Sailer, Xlrq, Jonathan Adler, Michael Munger, Steve Sailer again, Glenn Reynolds, Say Uncle, Jode Shoo, Singular Values, and
The Corner. Unfortunately, at this point, I am not allowed to really comment on this. One part of Levitt's letter that has not gotten any attention is the one that I think was his most important, his statement that:
The Chronicle of Higher Education has had a couple of articles on all this:

One point that wasn't directly mentioned by anyone is that Levitt's response when asked to backup is claim that others hadn't replicated my research was that the research papers were not refereed. Not only is Levitt acknowledging that the papers backed up and replicated my research, but he is admitting that the papers that did so were refereed.
The date on this letter does not match when I received it.
Update: See also this follow up filing.
Here is the exchange that Levitt had with economist John McCall on May 24th and 25th, 2005:
Email from John McCall to Steven LevittYou also state that others have tried to replicate [Lott’s] research and have failed. Please supply me with appropriate citations so that I might check for myself.
Email from Steven Levitt to John McCallThere was a NRC/ natl acad of sciences panel I was part of about research on guns that came out in 2004. That will point you in the right direction. . . .
Email from John McCall to Steven LevittHi Steve,
I went to the website you recommended -- have not gone after the round table proceedings yet -- I also found the following citations -- have not read any of them yet, but it appears they all replicate Lott's research. The Journal of Law and Economics is not chopped liver. . . .
Cordially,
John McCall PhD
Email from Steven Levitt to John McCallJohn,
It was not a peer refereed edition of the Journal. For $15,000 he was able to buy an issue and put in only work that supported him. My best friend was the editor and was outraged the press let Lott do this.

Email from John McCall to Steven LevittReturning to the $15,000 bribe issue of JLE and -- although I have not yet gone (I will find it tomorrow) to the NRC/natl. acad. of sciences panel you recommended -- I am wondering whether those deliberations were published somewhere, and, if so, who paid for that. Could such not have been essentially the same thing? I noticed that this issue of JLE was the results of a conference on crime safety and guns that was sponsored by AEI and the Yale Center for Studies in Law. I understand how your best friend the editor could have been outraged, and I hope he had the principle to resign his position in protest. However, we all eventually realize that an editor is but a small cog in a big wheel.
Email from Steven Levitt to John McCallJohn, if you read the paper by Duggan in JPE, and Ayres and Donohue in Stanford Law Review, and the NAS/NRC report (which was not paid for by anyone, it is done by the National Academy of Sciences), you will see the other side of the debate. Steve
