There’s mixed evidence of whether or not mass shootings have a contagion effect, that people who are already “primed” see this shit on tv and decide that today’s the day.
Or it could just be chance.
But maybe, here’s an idea, we don’t let people who make terroristic threats have guns. I don’t care about what kind of gun, if you credibly threaten to murder a bunch of people, no gun for you.
There have been a few articles on “herding” which I didn’t even know about before this election. I am no pollster, but it sounds like there’s a huge incentive to protect the reputation of the polling firm (“it’s a draw, so we can’t be wrong”) vs reporting numbers they think might make news.
