Gun Control & RKBA
In reply to the discussion: A recent thread sort of asked why we can't have cogent discussions about guns. [View all]flamin lib
(14,559 posts)1. He randomly surveyed 5000 phone numbers. The best information we have is that only 34% of households have guns, so 66% of his sample is flawed.
2. He had no way of verifying the data gathered; no police reports, no secondary witnesses, nothing. He just took their word for it.
3. He asked a question that guaranteed a very high false positive rate of response. People who own guns have a vested interest in defending that ownership, so when asked 'did you use your gun for self defense in the last 12 months' a lot of people said yes whether they did or not. A very high false negative response can be had by asking 'have you watched internet porn in the last year'. Anecdotal evidence for this high false positive came when the study was repeated but for only verified gun owners, one respondent reported using his/her gun 50 times in the last year.
4. He failed to correct for 'telescoping'. Did the respondents actually have a DGU in the last 12 months or was it 15 months?
5. He took the results of his flawed sample and extrapolated it to all households even though 66% did not have guns and therefore could not possibly have had a DGU.
The man does not know how to research and doesn't care to do quality work.
The CDC had one reference to his 2 million DGUs/year and gunners lap it up while at the same time denigrating every other study they've done.
Then you have Lott who admits to simply making up numbers and using false identity to applaud his own work. Yeah, like I'm going to respect these guy's work.
