In his new book Enlightenment Now and in his McLaughlin Lecture at the Cato Institute this week, Steven Pinker made the point that we may fail to appreciate how much progress the world has made because the news is usually about bad and unusual things. For instance, he said, quoting Max Roser, if the media truly reported the important changes in the world, "they could have run the headline NUMBER OF PEOPLE IN EXTREME POVERTY FELL BY 137,000 SINCE YESTERDAY every day for the last twenty-five years."
This is understandable. As Pinker writes,
News is about things that happen, not things that don't happen. We never see a journalist saying to the camera, "I'm reporting live from a country where a war has not broken out"—or a city that has not been bombed, or a school that has not been shot up. As long as bad things have not vanished from the face of the earth, there will always be enough incidents to fill the news, especially when billions of smartphones turn most of the world's population into crime reporters and war correspondents.
