More: 10 Pro-Gun Myths, Shot Down

By cutting off federal funding for research and stymieing data collection and sharing, the National Rifle Association has tried to do to the study of gun violence what climate deniers have done to the science of global warming. No wonder: When it comes to hard numbers, some of the gun lobby’s favorite arguments are full of holes.

Myth #1: They’re coming for your guns.
Fact-check: No one knows the exact number of guns in America, but it’s clear there’s no practical way to round them all up (never mind that no one in Washington is proposing this). Yet if you fantasize about rifle-toting citizens facing down the government, you’ll rest easy knowing that America’s roughly 80 million gun owners already have the feds and cops outgunned by a factor of around 79 to 1.

Myth #2: Guns don’t kill people—people kill people.
Fact-check: People with more guns tend to kill more people—with guns. The states with the highest gun ownership rates have a gun murder rate 114% higher than those with the lowest gun ownership rates. Also, gun death rates tend to be higher in states with higher rates of gun ownership. Gun death rates are generally lower in states with restrictions such as assault-weapons bans or safe-storage requirements.

Myth #3: An armed society is a polite society.
Fact-check: Drivers who carry guns are 44% more likely than unarmed drivers to make obscene gestures at other motorists, and 77% more likely to follow them aggressively.
• Among Texans convicted of serious crimes, those with concealed-handgun licenses were sentenced for threatening someone with a firearm 4.8 times more than those without.
• In states with Stand Your Ground and other laws making it easier to shoot in self-defense, those policies have been linked to a 7 to 10% increase in homicides.

Myth #4: More good guys with guns can stop rampaging bad guys.
Fact-check: Mass shootings stopped by armed civilians in the past 30 years: 0
• Chances that a shooting at an ER involves guns taken from guards: 1 in 5

Myth #5: Keeping a gun at home makes you safer.
Fact-check: Owning a gun has been linked to higher risks of homicide, suicide, and accidental death by gun.
• For every time a gun is used in self-defense in the home, there are 7 assaults or murders, 11 suicide attempts, and 4 accidents involving guns in or around a home.
• 43% of homes with guns and kids have at least one unlocked firearm.
• In one experiment, one third of 8-to-12-year-old boys who found a handgun pulled the trigger.
