You could argue that the world has never been better: war is increasingly rare, medical science has cured a number of the deadliest diseases, global poverty is down, life expectancy is up, and crime in America is down. But it sure doesn't seem that way, especially with Brexit, climate change, Trump, Syria, and terrorist incidents around the world.
Oliver Burkeman explores some of the reasons why we think the sky is continually falling and what we can do to be happy anyway. I have been thinking about this aspect of it recently:
And there is another, subtler reason you might find yourself convinced that things are getting worse and worse, which is that our expectations outpace reality. That is, things do improve -- but we raise our expectations for how much better they ought to be at a faster rate, creating the illusion that progress has gone into reverse.
