How data can help clarify the gun-control debate

According to the Centers for Disease Control and Prevention, 31,672 people died by guns in 2010 (the most recent year for which U.S. figures are available), a staggering number that is orders of magnitude higher than that of comparable Western democracies. What can we do about it? National Rifle Association executive vice president Wayne LaPierre believes he knows: “The only thing that stops a bad guy with a gun is a good guy with a gun.” If La Pierre means professionally trained police and military who routinely practice shooting at ranges, this observation would at least be partially true. If he means armed private citizens with little to no training, he could not be more wrong.

Consider a 1998 study in the Journal of Trauma and Acute Care Surgery that found that “every time a gun in the home was used in a self-defense or legally justifiable shooting, there were four unintentional shootings, seven criminal assaults or homicides, and 11 attempted or completed suicides.” Pistol owners’ fantasy of blowing away home-invading bad guys or street toughs holding up liquor stores is a myth debunked by the data showing that a gun is 22 times more likely to be used in a criminal assault, an accidental death or injury, a suicide attempt or a homicide than it is for selfdefense. I harbored this belief for the 20 years I owned a Ruger .357 Magnum with hollow-point bullets designed to shred the body of anyone who dared to break into my home, but when I learned about these statistics, I got rid of the gun.

It is too soon to tell what the motive was behind the accused James Holmes’ mass murder in a movie theater in Aurora, Colorado, especially now that he has stopped talking to the authorities in charge of his case. Reports about his personality, thoughts, and behaviors from friends, fellow students, professors, and the police are conflicting. He was smart, brilliant in fact. No, he wasn’t; he was a sub-standard student who dropped out of his doctoral program at the University of Colorado after failing a preliminary exam. He was a quiet man who said nothing to indicate he was on the verge of cracking. Also not true; he left an incoherent and rambling voice message on the phone service of a gun club he wanted to join, the owner of which noted: “It was this deep, guttural voice, rambling something incoherent. I thought, ‘What is this idiot trying to be?’.” He rigged his apartment with explosive devices but then warned the police about them after his capture. Initial reports described the event as spontaneous and random, but he mailed a notebook to his psychiatrist at his university describing in detail with diagrams precisely what he (pre)planned to do.

It may be months before we have any clue to his mind and motive. And short of something obvious like a brain tumor pressing against his amygdala (the brain’s emotion center)—similar to that in the brain of Charles Whitman, the University of Texas bell tower shooter who in 1966 killed 14 people and wounded 49, including himself, after leaving a note to authorities to autopsy his brain because he felt there was something wrong—we may never know the motive behind James Holmes murderous actions.

A court of law may determine the
meaning of replication in science

In the rough-and-tumble world of science, disputes are usually settled in time, as a convergence of evidence accumulates in favor of one hypothesis over another. Until now. (continue reading…)
