Humanity makes progress, kills fewer people


You would think that the disappearance of the gravest threat in the history of humanity would bring a sigh of relief among commentators on world affairs.

Contrary to numerous expert predictions, there was no invasion of western Europe by Soviet tanks, no escalation of a crisis in Cuba or Berlin or the Middle East into a nuclear holocaust. The cities of the world were not vaporised; the atmosphere was not poisoned by radioactive fallout or choked with debris that blacked out the sun and sent Homo sapiens the way of the dinosaurs.

Not only that, but (again, contrary to expert predictions) a reunified Germany did not turn into a Fourth Reich, democracy did not go the way of monarchy, and the great powers did not fall into a third world war but rather a “long peace”, which keeps getting longer. Surely the experts have been acknowledging such improvements?

No. The pundits are glummer than ever. And the pessimism is bipartisan. In 2007 the conservative writer Norman Podhoretz published a book called World War IV (on “the long struggle against Islamofascism”), and the liberal columnist Frank Rich wrote that the world was “a more dangerous place than ever”. If Rich is correct then the world was more dangerous in 2007 than it was during the two world wars, the Berlin crises of 1949 and 1961, the Cuban missile crisis, and all the wars in the Middle East. That’s pretty dangerous.

Why the gloom? Partly it’s the result of market forces in the punditry business, which favour Cassandras over Pollyannas. But mainly, I think, it comes from the innumeracy of our journalistic and intellectual culture. If we don’t keep an eye on the numbers, we end up with what has been called a false sense of insecurity.

The pessimism has been inspired by the “new wars” involving guerrillas and paramilitaries that plague the developing world. It has been stoked by the widely repeated (and completely bogus) meme that at the beginning of the 20th century 90% of war deaths were suffered by soldiers and less than 10% by civilians, but by the end of the century these proportions had been reversed. It has fed on the claim that the world learned nothing from the Holocaust, and that genocides are as common as ever. And of course it has been redoubled by terrorism, said to pose an “existential threat” to Western countries, to “do away with our way of life” or to end “civilisation itself”.

Each of these scourges continues to take a toll in human lives. But recently political scientists tried to measure how big a toll it is, and they have reached a surprising conclusion: all these kinds of killing are in decline.

Battle deaths per 100 000 of the world population have fallen from 300 during the height of World War II to the teens in the postwar years, single digits during the Cold War, and less than one in the 21st century. Other than in the war zones of Iraq and Afghanistan, deaths from terrorism in the past decade were far lower than they were in the 1970s and 1980s.

It’s not easy to see the bright side in the world today, where the remnants of war cause tremendous misery. The effort to quantify misery can seem heartless. But a better understanding of what has driven such numbers down can steer us towards doing things that make people better off. —
