Bad news surrounds us. Russia invading Ukraine. Fascism in Italy. Catastrophic floods in Pakistan. The criminalisation of abortion in parts of the USA. Melting glaciers. Bolsonaro (though hopefully not for much longer). Coming on the back of the worst pandemic in a century it’s hard to avoid the feeling that the world is entering a truly nasty period.
The science fiction writer Cixin Liu describes a civilisation on a planet orbiting two suns, trapped in what physicists call the three body problem – the chaotic, unpredictable motion traversed by three masses orbiting each other, radically different from the smooth path followed by a simple co-orbiting pair like the Earth and our sun. When the planet is relatively close to just one sun they enjoy a Stable Era – life evolves, civilization advances. But because of the three body problem, it is impossible to predict how long this will last before the onset of a Chaotic Era: the planet is either pulled close to both suns, burning all life to ashes, or drifts away from both suns, freezing all life in the cold of open space.
For Liu, these unpredictable catastrophes are a metaphor for China’s Cultural Revolution, as chaotic and unpredictable as it was destructive. Today many of us feel the Stable Era of the 1990s to 2008 – or perhaps even since the 1950s – is over, and we are about to be either fried in a nuclear conflict, or frozen as we can’t afford to pay sky-rocketing energy bills this winter.
At least, that’s how I and many of my friends and acquaintances feel. But if we’re honest, we’re hardly representative. Everyone is entitled to complain about their own burdens. Yet if we want to make a judgement about the state of the world – and people often do – then we need to take the time to look at some data. When we do that, our current downtick hardly makes a dent on the improvements in human well-being of the last half century. Child mortality, literacy, early deaths, it’s hard to find an indicator of global human well being that hasn’t improved in the last 10 years, and improved massively in the last 50.
