For some decades, about a hundred people have died a year in mass killings. For comparison, about fifty people die a year in lightning strikes, and about three hundred a year drown in their own bathtubs. All deaths are, of course, tragic, but clearly the news media, as well as most of the public, has lost a sense of perspective about the size of this problem.
Meanwhile, I can describe a few simple things that our society could do that would save north of a hundred thousand lives a year, and a few slightly more complicated ones that could save a total of couple hundred thousand a year.
We sadly have so little sense of proportion that we are willing to devote round the clock coverage for days to a risk that is astonishingly small and exceptionally difficult to fix, while we are unwilling to spend a tiny fraction of that effort on risks that are very likely to hit us personally and that are entirely straightforward to fix, like convincing hospitals to improve their process to reduce medical errors.
I sometimes despair for the human race. We have come so far, but we have so little capacity for thinking rationally about these sorts of issues, and that is sadly a matter of life and death.
