In the gun control debate, there seems to be a lot of bad data flying around. If we can't trust people to properly fill out a survey how are we going to address the issues?
It’s truly worse than you think! Read here from John Lott Jr.: Adam Lankford ‘botched’ study claiming U.S. accounts for one-third of mass shootings:A shock 2016 study argued that the U.S. accounted for nearly one-third of all mass shootings, sparking global headlines about the dangers of an American gun culture.Now another researcher says the original study “botched” the data.John R. Lott Jr., president of the Crime Prevention Research Center, crunched the numbers and said his count shows that the U.S. had less than 3 percent of the world’s mass public shootings over a 15-year period.snipMr. Lankford, who claimed to be the first to attempt a global survey, said his results suggested there was something to the American psyche that left people disaffected when they failed to achieve the American dream. He said they turn to violent outbursts with firearms.“It may thus be the lofty aspirations and broken dreams of a tiny percentage of America’s students and workers — combined with their mental health problems, distorted perceptions of victimization, delusions of grandeur, and access to firearms — that makes them more likely to commit public mass shootings than people from other cultures,” he postulated in his 2015 paper.Yet he has failed to post the data on all 292 shootings. Early academic critics said it’s easy to find data for U.S. shootings but trickier for tracking incidents in foreign countries.Mr. Lott, meanwhile, turned to data from the University of Maryland’s Global Terrorism Database and followed up with Nexis and web searches to try to catch cases that the database missed.He said good data exist only for recent years, so he looked from 1998 to 2012 and found 1,491 mass public shootings worldwide. Of those, only 43 — or 2.88 percent — were in the U.S. Divide that by per capita rates, and the U.S. comes in 58th, behind Finland, Peru, Russia, Norway and Thailand — though still worse than France, Mexico, Germany and the United Kingdom.snip.He Lott has released a 451-page appendix detailing each of the shootings and his thoughts on how he classified it, and he shared his data with other academics, including, he said, Mr. Lankford.So, a sensational report detailing the terrible state of US Firearms Mass killing is issued and the source data? Never released, so no possibility of a Peer Review.A follow-up, with expanded & significantly more data (to the tune of 6x the number of data points) shows the total opposite. AND ALL OF THE DATA IS PUBLISHED IN A DETAILED APPENDIX SET!
