While it is easy to be aware of all the bad things happening in the world, it's harder to know about the good things. The silent miracle of human progress is too slow and too fragmented to ever qualify as news. Over the past 20 years, the proportion of people living in extreme poverty has almost halved. But in online polls, in most countries, fewer than 10% of people knew this. Our instinct to notice the bad more than the good is related to three things: the misremembering of the past; selective reporting by journalists and activists; and the feeling that as long as things are bad, it's heartless to say they are getting better. Stories about gradual improvements rarely make the front page even when they occur on a dramatic scale and affect millions of people. And thanks to increasing press freedom and improving technology, we hear about more disasters than ever before. This improved reporting is itself a sign of human progress, but it creates the impression of the exact opposite. How can we help our brains to realise that things are getting better? Think of the world as a very sick premature baby in an incubator. After a week, she is improving, but ... her health is still critical. Does it make sense to say that the infant's situation is improving? Yes. Does it make sense to say it is bad? Yes, absolutely. Does saying "things are improving" imply that everything is fine, and we should all not worry? Not at all: it's both bad and better. That is how we must think about the current state of the world.
