Do fewer guns mean fewer firearm deaths? If you believe the March 6th issue of the Journal of the American Medical Association of Internal Medicine, the answer is "yes."
A study by Eric Fleegler and four other co-authors received massive national news coverage from USA Today to the television networks.
But the report is based on embarrassingly bad statistics that are rigged to get the result the authors wanted.
Take how they measure gun ownership. Believe it or not, this study measures gun ownership by looking at the share of suicides committed using firearms.
Then the authors go on to commit an egregious and basic statistical error. They claim that states with higher gun ownership have higher gun death rates. But wait a second — most gun deaths are gun suicides. And what they call "gun ownership" in their study is also measured by gun suicides.
In other words, all the study proves is that more gun suicides leads to, well — more gun suicides. Any serious statistical journal would not have published such nonsense.
The Fleegler study also involves a geographic comparison across the 50 U.S. states . . . .
