gregladen | April 12, 2010I would wager that you don't know where many of your most important files are. If you are into music, and use iTunes, you can't find a particular song file using your file manager. You would need to locate it using iTunes. iTunes would then give you limited access to that file. It does not let you do the same thing your file manager would let you do. Many of your most important pieces of information are in emails or attached to emails. Where exactly are those things? Can you access them with your file manager with little effort, print, copy, delete, duplicate, or otherwise work with…

1) Did I Attribute the 98 Percent Brandishing Number to Others? No
Apparently, some credence is being given to the claim that I have attributed the 98 percent brandishing estimate to others instead of myself. Some are taking this as evidence that I never conducted the survey. Yet, the fact is I never attributed this number to anyone else other than myself. It is claimed that I attributed this number to Gary Kleck on…

Anyone who has looked closely at the data used by John Lott in coming up with his “findings” in More Guns, Less Crime (MGLC) would come to the same conclusion, MGLC = GIGO. First, the data are so full of holes as to be unusable for the analyses he conducted. Second, Lott badly miscalculated the crime rates. Third, he ignored a major discontinuity in the data. [And fourth, as Ayres and Donohue have shown, even if the first three points were not valid (which they are), he did it wrong.] It’s a bit technical, so bear with me.

I take issue with two points of Jim Lindgren?s representation of my statements about John Lott?s 1997 survey, as posted on instapundit.com.
Claim that I backed off my comments about what I knew about Lott's survey during a previous conversation with Frank Zimring
I did not back off my comments that I made to Frank in our first conversation (which I believe was about July 1, 2002) when he called me to ask some very specific questions about my…
tlambert | June 5, 2003In The Latest Misfires in Support of the More Guns, Less Crime Hypothesis Ayres and Donohue write:In the wake of some of the criticisms that we have leveled against the Lott and Mustard thesis, John Lott appeared before a National Academy of Sciences panel examining the plausibility of the more guns, less crime thesis and presented them with a series of figures showing year-by-year estimates that appeared to show sharp and immediate declines in crime with adoption of concealed-carry laws. David Mustard even included these graphs in his initial comment…

This discussion is concerned with four topics: (1) Lott’s references to, remarks about, and discussions of DGU statistics originating in sample surveys or polls carried out by other investigators; (2) Lott’s claims about a survey he says he conducted in 1997; (3) Lott’s reports on a survey he conducted in 2002; (4) several matters that have proved to be distractions from the careful consideration of the foregoing. Section (5) presents my conclusions. They may be read at once by anyone who has followed closely the Internet exchanges about the Lott case.
Before proceeding, I…

Background
John and I started working on our concealed carry paper in the fall of 1995. I was finishing my Ph.D. in Economics at the University of Chicago, and John was a faculty member. We worked on our paper intensively from about February 1996 to September 1996. We presented it at the American Law and…

Guns make it easier for bad things to happen, but they also make it easier for people to stop crime and prevent bad things from happening. The important question that ultimately concerns everyone is the net effect, whether on net guns save lives or cost lives and whether they increase or decrease violent crime that threaten so many…

This pages documents direct and indirect references Lott has made to a survey he claims to have carried out in 1997. Further analysis is here, and the latest update is here.The information of over 2 million defensive uses and 98 percent is based upon survey evidence that I have put together involving a large nationwide telephone survey conducted over a three month period during 1997.

The discussions on so many blogs on the Lott case have been invaluable not only in turning up new evidence but also in illustrating the wide variety of reactions to the evidence. One thing that strikes a professional researcher is that many who have commented do not look at such cases in the way that researchers are trained to do. What this case is about is the professional work of a a social scientist, and the question is whether that work meets the ethical standards of scientific inquiry and reporting. And commentators are not at liberty to define…

My wife, who took care of our taxes, has a discussion below about how the forms were completed. The main point is that all payments to research assistants if documented by check went into the professional services category. This also includes other expenses that they might have incurred in their work such as their telephone expenses, xeroxing and the like. On the business form, we list out expenses that we directly make ourselves.
As to claims that…
tlambert | January 21, 2003Tim Lambert's questions:
Why did Lott repeatedly make false claims that the 98% figure came from other studies and from Kleck?
Even Lott cannot possibly be sure that the correct result of his survey was 98% since there is no way to check his calculations. Why did he repeat the figure over and over again?
Lott has conceded that the size of the defensive gun use sample in his survey was very small. Too small, in fact, for the result to be statistically reliable. Why did he never even mention the markedly different results obtained from the other surveys…
tlambert | January 19, 2003[This is an email sent to John Lott that Lott posted to the firearmsregprof mailing list on January 20, 2003.]
I believe that in my emails to you and in my conversation with James Lindgren, I have stimulated just about all of my memories and impressions that I'm going to have concerning the survey that I took, without having any substitutions and additions by any possible suggestion, express or implied. I do not wish to be seen as a partisan in this matter, for I am not. I also am unwilling to speculate. My recollections and impressions of the survey that I took are now closed to prevent any…

Response to Lindgren's January 17th posting:
Lindgren's role in this process seems to be that of a prosecutor. [This is not correct. Lindgren is careful to present any evidence that supports Lott. ] He claims that he "never heard of a professor doing anything of that size with no funding . . . ." Well, I did the 2002 survey paying students $10 per hour out of…

The web is, of course, not perfectly reliable, and items appearing there can later disappear. This approximately chronological listing is probably incomplete, and we welcome additions and corrections.
