Believe it or not, things are getting better and better

This book review is from The Economist and worth sharing, I think.

The state of the world
Better and better

Human life has improved in many ways, both recently, according to a Swedish economic historian, and in the 19th century

Progress: Ten Reasons to Look Forward to the Future.
By Johan Norberg. Oneworld; 246 pages;

HUMANS are a gloomy species. Some 71% of Britons think the world is getting worse; only 5% think it is improving. Asked whether global poverty had fallen by half, doubled or remained the same in the past 20 years, only 5% of Americans answered correctly that it had fallen by half. This is not simple ignorance, observes Johan Norberg, a Swedish economic historian and the author of a new book called “Progress”. By guessing randomly, a chimpanzee would pick the right answer (out of three choices) far more often.

People are predisposed to think that things are worse than they are, and they overestimate the likelihood of calamity. This is because they rely not on data, but on how easy it is to recall an example. And bad things are more memorable. The media amplify this distortion. Famines, earthquakes and beheadings all make gripping headlines; “40m Planes Landed Safely Last Year” does not.

Pessimism has political consequences. Voters who think things were better in the past are more likely to demand that governments turn back the clock. A whopping 81% of Donald Trump’s supporters think life has grown worse in the past 50 years. Among Britons who voted to leave the European Union, 61% believe that most children will be worse off than their parents. Those who voted against Brexit tend to believe the opposite.

Mr Norberg unleashes a tornado of evidence that life is, in fact, getting better. He describes how his great-great-great-great grandfather survived the Swedish famines of 150 years ago. Sweden in those days was poorer than Sub-Saharan Africa is today. “Why are some people poor?” is the wrong question, argues Mr Norberg. Poverty is the starting point for all societies. What is astonishing is how fast it has receded. In 1820, 94% of humanity subsisted on less than $2 a day in modern money. That fell to 37% in 1990 and less than 10% in 2015.

Not only have people grown much more prosperous; they also enjoy better health than even rich folk did in the past. This is due partly to galloping progress in medical science. When the swine flu pandemic threatened to become catastrophic in 2009, scientists sequenced the genome of the virus within a day and were producing a vaccine in less than six months.

The spread of basic technology, allowing for clean water and indoor plumbing, may have helped even more. Louis XIV’s palace was the pinnacle of 18th-century grandeur. Nonetheless, without flush toilets, it stank. “The passageways, corridors and courtyards are filled with urine and faecal matter,” wrote a contemporary observer. Now 68% of the world’s population have modern sanitation—a luxury denied to the Sun King—up from 24% in 1980.

People are growing smarter too. Americans scored, on average, 100 points on IQ tests just after the second world war. By 2002, using the same test, this had risen to 118, with the biggest improvements in answers to the most abstract problems. This “Flynn Effect”, as it is known, is observed in all countries that have modernised. The most likely reasons are better nutrition and the spread of education—brains that are well-fed and well-stimulated tend to work better—and environmental improvements such as the removal of lead from petrol.
