When you hear about something terrible, calm yourself by asking, If there had been an equally large positive improvement, would I have heard about that? Even if there had been hundreds of larger improvements, would I have heard? Would I ever hear about children who don’t drown? Can I see a decrease in child drownings, or in deaths from tuberculosis, out my window, or on the news, or in a charity’s publicity material?
