Bad Record Of Doom Mongering And Interest Group Politics

Here is Matt Ridley on the dismal track record of doom mongerers (or the pessimism bias). [hat tip Mark Perry] (all bold emphasis mine)

``By then I had begun to notice that this terrible future was not all that bad. In fact every single one of the dooms I had been threatened with had proved either false or exaggerated. The population explosion was slowing down, famine had largely been conquered (except in war-torn tyrannies), India was exporting food, cancer rates were falling not rising (adjusted for age), the Sahel was greening, the climate was warming, oil was abundant, air pollution was falling fast, nuclear disarmament was proceeding apace, forests were thriving, sperm counts had not fallen. And above all, prosperity and freedom were advancing at the expense of poverty and tyranny.

``I began to pay attention and a few years ago I started to research a book on the subject. I was astounded by what I discovered. Global per capita income, corrected for inflation, had trebled in my lifetime, life expectancy had increased by one third, child mortality had fallen by two-thirds, the population growth rate had halved. More people had got out of poverty than in all of human history before. When I was born, 36% of Americans had air conditioning. Today 79% of Americans below the poverty line had air conditioning. The emissions of pollutants from a car were down by 98%. The time you had to work on the average wage to buy an hour of artificial light to read by was down from 8 seconds to half a second.”

The incentives for doom mongering? Apparently “interest Group politics”

Back to Mr. Ridley…

``I now see at firsthand how I avoided hearing any good news when I was young. Where are the pressure groups that have an interest in telling the good news? They do not exist. By contrast, the behemoths of bad news, such as Greenpeace, Friends of the Earth and WWF, spend hundreds of millions of dollars a year and doom is their best fund-raiser. Where is the news media's interest in checking out how pessimists' predictions panned out before? There is none. By my count, Lester Brown has now predicted a turning point in the rise of agricultural yields six times since 1974, and been wrong each time. Paul Ehrlich has been predicting mass starvation and mass cancer for 40 years. He still predicts that `the world is coming to a turning point'.

``Ah, that phrase again. I call it turning-point-itis. It's rarely far from the lips of the prophets of doom. They are convinced that they stand on the hinge of history, the inflexion point where the roller coaster starts to go downhill. But then I began looking back to see what pessimists said in the past and found the phrase, or an equivalent, being used by in every generation. The cause of their pessimism varied - it was often tinged with eugenics in the early twentieth century, for example - but the certainty that their own generation stood upon the fulcrum of the human story was the same.

``I got back to 1830 and still the sentiment was being used. In fact, the poet and historian Thomas Macaulay was already sick of it then: `We cannot absolutely prove that those are in error who tell us that society has reached a turning point, that we have seen our best days. But so said all before us, and with just as much apparent reason.' He continued: `On what principle is it that, when we see nothing but improvement behind us, we are to expect nothing but deterioration before us.'

Let us back this up with some graphs (source google public data)

Bottom line: Beware of the false 'politically tainted' messiahs.
