Well one thing one can do is ask if the survey data make sense in light of other 
sources of data we have. I'm _told_ that if you project the number of certain specific 
types of crimes that were supposedly prevented, according to the survey, that you get 
numbers that are many times larger than the actual number of those crimes committed. 
This doesn't seem plausible given that most people don't carry their guns with them 
when they are out on the street where the vast majority of crimes are committed.  
(Since I don't have a cite for this I'm not claiming its true, just suggesting it as a 
methodology.)  

Another thing one can do is compare error rates on verifiable items of a comparable 
nature. For example a lot more people report that they are managers than actually 
are (as verified by their employers). Since a lot of people would probably consider it 
heroic to fight of a criminal with a gun I wouldn't be surprised if people engaged in 
a similar sort of wishful thinking on this question. This approach in particular 
suggests that _all_ the reports in the survey could easily be in error (which doesn't 
mean that no one ever uses a gun in self-defense, just that you would need a much 
bigger sample to find them and accurately calculate the true rate).

One could look at published reports of crimes and attempted crimes and look at the 
fraction of reported incidents in which victims were armed. Of course there is going 
to be reporting bias, but isn't this why the whole issue of brandishing vs 
discharging is important? We expect that if people have to discharge their weapons 
in self defense then we will read about it in the paper and we should be able to get 
an accurate estimate of how important gun use in self defense is from such sources. 
Suppose we never hear about cases where criminals are scared off by someone 
brandishing a gun but we always hear about it when a criminal is shot. My 
understanding is that reports of the latter are very rare. If they account for 25% of 
crimes prevented then there aren't many crimes prevented (4x reports), but if 98% of 
the time all one has to do is show the gun then the number of crimes prevented is 50x 
the number of reports and is considerably more important. Thus the difference between!
 75% and 98% is very very substantive. A difference between 98% and 90% would mean 
1/5th as many crimes prevented. 

Is self-defense just one of those issues where we'll never have decent
data? 

Yes, but that doesn't meant that we can't learn from what data are available. My 
understanding is that depending on how you come at this issue you reach very different 
conclusions. If what I have been told by people I trust on these issues is true, there 
is very little evidence supporting the view that guns are frequently used in defense 
against criminals other than survey data and anecdote. - - Bill Dickens

One possibility would be to check for consistency with other measures.

Suppose, for example, one had a poll of criminals, taken in some 
situation where they had no reason to lie. Every case of a victim 
frightening a way a criminal by brandishing a gun at him ought in 
principle to show up on both sides of the transaction.

For an analogous case, one can check poll results on sexual activity

It's my understanding that Kleck uses FBI crime statistics in his 
computations.

Those are estimates of the active use of firearms to deter crimes.  It 
appears that the ownership of firearms also passively discourages crimes:  
while the US has a hire rate of public crime than in Europe, the Europeans 
have higher rates of home breakins and so forth.  In Europe a criminal knows 
that people won't be armed at home; in America a criminal has a much higher 
chance of finding unarmed people in public than in homes.

I understand that every state that's adopted general concealled carry has 
seen significant drops in public crime rates; Florida saw its homicide rate 
go from 50% above the national average to just below it in the year after 
adopting general concealled carry.  

I understand also that since the big Australian and British gun confiscations 
of the 1990s that both countries have been beset by large increases in crime 
while crime rates in America (and indeed often the actual number of crimes) 
has continued to decline.

The thing that makes me extremely skeptical of these numbers is that 
I don't know a single gun owner who carries his/her gun outside the 
house unless the trip is to use the gun (to hunt or for target 
shooting). The vast majority of crimes against individuals are not 
perpetrated against people who are at home with their guns. For 
these numbers to be right I suspect there would have to be a whole 
lot more people carrying concealed weapons or a  whole lot more home 
invasions that statistics would suggest. - - Bill Dickens

I'm not sure of just how the figures are stated. What about business 
owners in high crime neighborhoods? I can imagine lots of cases where 
the owner has a gun behind the counter or wherever, pulls it, and the

Two last comments on the Lott business.  First, there is a reasonably good
summary by Tim Noah in Slate,
http://slate.msn.com/id/2078084/

Second, a private email pointed out that in my deeply cynical post on Lott,
my reference to the Lott discussion was about the whole dispute, much of it
on web logs, not just the Armchair discussion.  So my post very misleadingly
sounded like an attack on Bill Dickens, the only critic of Lott on the list.
It was not intended as such, because the criticisms Bill makes of Lott are
fair, although I think overstated.  My apologies.

2003-02-04 Thread Grey Thomas
Thanks for the link about Slate, but there is something fairly annoying.

Lott claims:
  In 98 percent of the cases, such polls show, people simply brandish the weapon to 
stop an attack.

Tim Noah, disputes this, yet also FAILS to say what the polls do show. 
But polls by the Los Angeles Times, Gallup, and Peter Hart show no such thing.

So what do they show? 95% 50% 88.8%?  If it's over 90%, then Lott's exageration is
not such a big deal.

Tim's other attack is on the fake persona.  But I agree more with D. Friedman about 
accepting fakes on the internet.  As an aside, CIAO is an org where, among other 
things, reviewers review lots of stuff -- including other reviewers.  And they can 
signify trust in various reviewers.

On the other hand, Lott doing this makes me trust him much less.

 He represented himself as someone who had taken courses from himself and
presented testimonials about his character from that persona. That isn't
lying?

I confess I find the whole discussion of John Lott a bit bizarre, although
it may be that after nearly two decades of working as a full time academic,
I am willing to settle for academics who do not commit battery on their
colleagues (I have seen it more than once, and it has been unpunished).  I
am not pleased by Lott's presenting false testimonials, although given the
massive personal assault he has endured since his book, it does not surprise
me a lot.  It is unusual academic behavior.  In my experience, academics are
more inclined to stick to anonymity when they start libelous rumors about
other academics.

But if we are going to talk about firing people, then it seems to me that a
little consistency is in order.  Remember the JMCB replication project, that
ended with piles of irreproducible papers?  I do not recall that leading to
dismissals.  Lott has his data sets available, online.  I had no economist,
now at Harvard, tell me he would not publish in the AER once they started
demanding that data sets be revealed.  I do not think he was hiding fraud,
just acknowledging that the profession offers zero rewards for putting
together a good data set, and he did not want anyone to beat him to
publications.  Nevertheless, if replication is the hallmark of science, then
Lott is among the least of the profession's sinners.  I have rarely had an
economist refuse to share a data set; they just ignore the request.  So let
us start with the serious offenses.  Should every failure to share data be a
firing offense?  What if you share the data and your published results are
reproducible?  Those of not at think tanks have to teach.  A former
colleague walked into a seminar one day, completely unprepared, with his
coffee cup, and spent two hours telling grad students they should think of
questions to ask about the coffee cup.  He called this cupology.  Will every
case of unprepared teaching gets the same scrutiny, or is it just the
politically unfashionable Lott who gets scrutiny..

Lott's offense strikes me as trivial by academic standards.  I am willing to
cooperate with pillorying Lott if every academic gets the same degree of
scrutiny.

David, I wouldn't dispute his son's or his wife's right to write the review or use 
assumed names. However, if any member of my family did that (particularly if they 
were using my pen name as in this case) I would certainly ask them not to as I 
would consider it very dishonest. Using a pen name isn't necessarily a breach of 
ethics, but if the purpose would be to cover up ones personal relationship to the 
author, it certainly is. That is information that should affect how people reading 
the review interpret it (I would put less weight on a review of one of my books from 
my family than from an anonymous third party).  Further, if my family went ahead and 
submitted the review, despite my request that they not do it, I would inform Amazon 
of their true identities. I would hope that I would do this without any extrinsic 
incentive simply because it would be the right thing to do, but in part I would do it 
because I would be scared silly that:

1) people would think that I had written the review and had committed a serious breach 
of academic ethics (there would be no way to prove that I didn't if the review is 
submitted from my home computer) . 
2) Such a breach of ethics would rightly call into question my integrity and therefore 
my reliability as a scholar. I wouldn't think it at all unreasonable for people to 
believe that someone who played fast and loose with truth in one arena wouldn't in 
others. Most of the value of an academic work is lost if you can't trust the written 
to accurately represent the facts. If you have to check every footnote and re-run 
every regression that someone presents in most cases there is little point in reading 
what they write. 
3)  The perceived loss of integrity would adversely affect all my colleagues at 
Brookings as people would rightly ask what sorts of standards Brookings was applying 
in its hiring. 
4) I would therefore expect that the institution would investigate the facts of the 
matter and finding that I took no action to stop the publication of the deceptive 
review or to inform the public of its deceptive nature once it was published that I 
would be fired to protect the reputation of the institution.

Not about the issues involved.  The debate is about
violent crime, not Lott.  Frankly, given that he was
writing under a pen name, I think it is funny that
he'd make up a goofy little story about himself.  It
did have him saying to take listen to other economists
and get difference views after all.

If under his nom de plume, or however it's spelled, he
fairly represented the facts and arguments of the
gun-control debate, then he's committed no
transgression--other than having a little fun.

Probably the only reason he shouldn't have done it is
that the state of logical reasoning in our society is
so poor that ad hominems have considerable weight with
alot of people.  He has probably given fodder to those
whose rhetorical style is a little, for lack of a
better phrase, ad captandum vulgus.

More to the point. Allowing a family member to submit
a review of a book under a false name is a pretty
serious breach of academic integrity.

To amazon.com?  I don't know about that.  The forum
operates under effective anonymity, with no
references, virtually no standards, and little (if
any) editorial review.  His kid writes a review and
submits it to amazon.com under his pen name?  I don't
see the harm.
