Welcome to Matt Ridley's Blog

Here is a letter I sent to the editor and deputy editor of The Economist.

A comment on the piece by James Astill about the Berkeley temperature study. Most of the article is a sensible discussion of a deadly dull piece of statistics that changes nothing. But it's topped and tailed with claims that this leaves little room for doubters, and that the warming is "fast". Both these conclusions are badly wrong.

Latest Mind and Matter column in the Wall Street Journal is the extraordinary story of modern chicken genetics.

Of all the amphibians, reptiles, birds and mammals in the world, the most abundant species is probably the chicken. At any one time, approximately 20 billion cocks and hens are alive on the planet (though never for long).

Donna Laframboise is a journalist and civil libertarian in Toronto, who made her name as a fearless investigative reporter in the 1990s. She has recently been investigating the Intergovernmental Panel on Climate Change and has come up with startling results about how its reports are compiled. For those of us who took the IPCC's evaluations of climate at face value when they came out -- I know I did -- and thought that they were based on an impartial and careful process that relied on peer reviewed evidence, these revelations are shocking. Her book The Delinquent Teenager is now available on kindle and will shortly be in paperback. It is one of the most important pieces of investigative journalism in recent years. It demolishes the argument that we need the mainstream media because the blogosphere will never do the hard work of investigative journalism. The opposite is true.

Here I take the liberty of extracting one fairly lengthy tale from the book, but there are many more:

The IPCC's transparency shortcomings have been obvious for some time. In 2005 Steve McIntyre, a Canadian with a PhD Masters degree in mathematics and a flair for statistics, was invited by the IPCC to be an expert reviewer for what would become the 2007 edition of the Climate Bible. McIntyre, who writes theClimateAudit.org blog, was by then a well-known IPCC critic, so this invitation was a promising sign. But it didn't take long for matters to go off the rails.

Here's my latest Mind and Matter column from the Wall Street Journal:

Writing about science carries the risk of embarrassment. If you champion a theory and it gets disproved, you have some explaining to do. So it is nice when a theory you choose does win the race.

Here's an article I wrote for this week's Spectator about UK energy policy. Wind must give way to gas before it ruins us all, and our landscapes.

Which would you rather have in the view from your house? A thing about the size of a domestic garage, or eight towers twice the height of Nelson's column with blades noisily thrumming the air. The energy they can produce over ten years is similar: eight wind turbines of 2.5-megawatts (working at roughly 25% capacity) roughly equal the output of an average Pennsylvania shale gas well (converted to electricity at 50% efficiency) in its first ten years.

Difficult choice? Let's make it easier. The gas well can be hidden in a hollow, behind a hedge. The eight wind turbines must be on top of hills, because that is where the wind blows, visible for up to 40 miles. And they require the construction of new pylons marching to the towns; the gas well is connected by an underground pipe.

From My latest Mind and Matter Column at he Wall Street Journal:

The science of evolutionary psychology has flourished in recent years by asking "why" as well as "how" questions about animal and human behavior, and answering them with historical explanations.

I have a book review in the Wall Street Journal of Robert Laughlin's book Powering the Future.

These are the first two paragraphs:

Many environmentalists believe that carbon dioxide from the burning of fossil fuels will cause a climate crisis toward the end of this century. Environmentalists also raise the alarm that we have reached "peak oil" and that fossil fuels will run out by the middle of the century. That both views cannot be true rarely seems to bother those who hold them. Either consequence, we're told, makes the world's conversion to a low-carbon energy system an urgent matter.

My latest Mind and Matter column for the Wall Street Journal is on metaphors and analogies:

Monkeys can reason by using analogy, it seems. In an experiment recently reported in the journal Psychological Science, baboons in a lab proved capable of realizing that a pair of oval shapes is "like" a pair of square shapes and "unlike" a pair made of two different shapes. This finding suggests that you can have analogy without language.

Fascinating interview with the founder of Continental Resources Harold Hamm in the Wall Street Journal.

Harold Hamm calculates that if Washington would allow more drilling permits for oil and natural gas on federal lands and federal waters, the government could over time raise $18 trillion in royalties. That's more than the U.S. national debt.

The Bakken oil fields of North Dakota are proving to be huge. possibly 24 billion barrels.

I have an op-ed article in the Times today, arguing that there is light at the end of the tunnel for the world's and the British economy: the long-term gains from living within our means are huge:

Matthew Parris hit a nerve last Saturday with his argument that we have lived beyond our means and must now expect to have to work harder and be 25 per cent poorer. It resonated with me as well as many readers. He cut through all the detail of debt, default and deficits to extract an essential truth. The West has run a pyramid scheme, spending borrowed capital to boost current living standards. From pensions to mortgages, from public spending to consumer extravagance, the reckoning has arrived.

Here is my latest Mind and Matter column in the Wall Street Journal

There are many mysteries about Ray, the 17-year-old English-speaking "forest boy" who walked into the city hall in Berlin on Sept. 5, claiming to have lived wild in the woods for five years with his father-until his father recently died in a fall. Judging by his rucksack and his speech, he was not a fully feral child, reared by wild animals and unacquainted with language.

I have the following  opinion piece in today's Wall Street Journal, adapted from my forthcoming Hayek lecture.

The crowd-sourced, wikinomic cloud is the new, new thing that all management consultants are now telling their clients to embrace. Yet the cloud is not a new thing at all. It has been the source of human invention all along. Human technological advancement depends not on individual intelligence but on collective idea sharing, and it has done so for tens of thousands of years. Human progress waxes and wanes according to how much people connect and exchange.

I published this article in the Ottawa Citizen today:

The world now has almost seven billion people and rising. The population may surpass nine billion by 2050. We, together with our 20 billion chickens and four billion cattle, sheep and pigs, will utterly dominate the planet. Can the planet take it? Can we take it?

My latest Mind and Matter column for the Wall Street Journal is on drug development and network analysis:

Here's a paradox. Every week seems to bring news from a research laboratory of an ingenious candidate cure about to enter clinical trials for a serious disease. Yet the productivity of drugs coming out of clinical trials has been plummeting, and the cost per drug has been rocketing skyward. The more knowledge swells, the more pharmaceutical innovation fails. What's going on?

My latest Wall Street Journal Mind and Matter column discusses conspiracy theories.

Michael Shermer, the founder and editor of Skeptic magazine, has never received so many angry letters as when he wrote a column for Scientific American debunking 9/11 conspiracy theories. Mr. Shermer found himself vilified, often in CAPITAL LETTERS, as a patsy of the sinister Zionist cabal that deliberately destroyed the twin towers and blew a hole in the Pentagon while secretly killing off the passengers of the flights that disappeared, just to make the thing look more plausible.

He tells this story in his fascinating new book, "The Believing Brain." In Mr. Shermer's view, the brain is a belief engine, predisposed to see patterns where none exist and to attribute them to knowing agents rather than to chance-the better to make sense of the world. Then, having formed a belief, each of us tends to seek out evidence that confirms it, thus reinforcing the belief.

My TED talk onWhen Ideas Have Sexhas now passed 750,000 views.

Latest Wall Street Journal  column is on how anti-virals outwit natural selection:

Draco, who wrote Athens's first constitution in about 620 B.C., decreed that just about every crime should be punishable by death, because that was what petty criminals deserved and he could think of no harsher penalty for serious criminals. "Draconian" means indiscriminate as well as harsh.

Back in June, I could not make it to Idea City in Canada,  meeting that chose "ideas having sex as its slogan". But I recorded a talk by Skype and here it is.

I have a piece in today's Times newspaper on extinction of species. Here it is, with added links:

The suitably named Dr Boris Worm, of Halifax, Nova Scotia, led the team that this week estimated the number of species on the planet at 8.7 million, plus or minus 1.3 million. That sounds about right. We human beings have described almost all the mammals, birds, butterflies and other conspicuous creatures, but new beetles, wasps, moths, flies and worms abound in every acre of tropical forest.

Some patterns are clear. Most species are on land; marine life, though just as abundant, is slightly less diverse. Most are in the humid tropics; the rest of the globe is an ecological footnote to the rainforest. Most are animals - though plants, fungi and microbes vastly outweigh us beasts, they tend to come in fewer kinds, perhaps because plants hybridise and bacteria swap genes, blurring the boundaries of species. Most are insects: spiders/mites and molluscs take silver and bronze, but if Planet Earth had a mascot, it would be a ground beetle.

Latest Mind and Matter column from the Wall Street Journal:

Evolutionists long ago abandoned the idea that natural selection can promote only selfish behavior. In the right circumstances, animals-including human beings-evolve the instinct to be nice (or acquire habits of niceness through cultural evolution). This happens within families but also within groups, where social solidarity promotes the success of the group at the expense of other groups.

My latest Mind and Matter column in the Wall Street Journal:

Hardly any subject in science has been so politically fraught as the heritability of intelligence. For more than a century, since Francis Galton first started speculating about the similarities of twins, nature-nurture was a war with a stalemated front and intelligence was its Verdun-the most hotly contested and costly battle.

My latest Mind and Matter column in the Wall Street Journal:

What limits the size of a peacock's tail, the weight of a deer's antlers or the virtuosity of a songbird's song? Driven inexorably by the competition to attract mates, these features of animals ought to get ever more elaborate. There was even once a theory-now discredited-that the famously gigantic antlers of the Irish elk became so unwieldy that they caused its extinction. Yet sexual ornaments do not get ever bigger.

Here is a piece I just published in the Spectator.

Johnny Berliner made this charming little calypso account of genes and what they are made of. It's concise and precise as well as nice. (Calypso rhyming is catching)

Latest Mind and Matter column in the Wall Street Journal

"It's strange that I could become a professional athlete," said the Australian winner of this summer's Tour de France, Cadel Evans. "Physically, I was completely unsuitable for almost all Australian school sports. Nearly all Australian school sports require speed and/or size."

Belatedly, here is last week's Mind and Matter column from the Wall Street Journal.

I once had a soft spot for the yeti, known in my youth as the "abominable snowman." As a teenager I avidly devoured stories of hairy bipeds glimpsed through snowstorms, strange cries echoing across glaciers, or enigmatic footprints in the snow. Slowly it dawned on me that the testimony was unreliable, the ecology implausible, the demography impossible and the lack of specimens conclusive.

I heartily recommend a new book called "And the Band Played On" by Christopher Ward, a friend of mine. It's a best-seller already in the UK. It's about his grandfather, who was the violinist in the band that played as the Titanic sank. But it's not about the sinking, but about what happened afterwards, and in particular the feud that broke about between the violinist's father and his pregnant fiancee's family. It's an astonishing tale of fraud, hoaxes, lawsuits, imprisonment and cruelty that would make a fiction writer blush at having exaggerated.

But, for the purposes of this website, what struck this rational optimist most was the examples of how non-good were the good old days. A world in which a ship's musician has to buy his own uniform on credit, to be deducted from his wages, is not very nice. But a world in which those wages were stopped by his employer at 2.20am on 14 April 1912 is shockingly awful. And a world in which his father then receives a letter pointing out that the wages having been stopped, there is still a sum owing for the uniform buttons, which the father should settle by return -- takes the biscuit. This was also a world in which a seventeen year old girl who devised a cruel hoax to get revenge on her father and stepmother was imprisoned in a brutal jail awaiting trial for deception. Yet I suspect Scotland in 1912 was a lot kinder than it was in 1812 or 1712.

Next time the Archbishop of Canterbury or some pontificating busybody tells me the world is getting worse because people are so much more selfish these days, I will suggest they read this book.
