Welcome to Matt Ridley's Blog

My Times column on identity politics:

The student union at King’s College London will field a team in University Challenge that contains at least 50 per cent “self-defining women, trans or non-binary students”. The only bad thing Ken Livingstone could bring himself to say about the brutal dictator Fidel Castro was that “initially he wasn’t very good on lesbian and gay rights”. The first page of Hillary Clinton’s campaign website (still up) has links to “African Americans for Hillary, Latinos for Hillary, Asian Americans and Pacific islanders for Hillary, Women for Hillary, Millennials for Hillary”, but none to “men for Hillary”, let alone “white people for Hillary”.

Since when did the left insist on judging people by — to paraphrase Martin Luther King — the colour of their skin rather than the content of their character? The left once admirably championed the right of black people, women and gays to be treated the same as white, straight men. With only slightly less justification, it then moved on to pushing affirmative action to redress past prejudice. Now it has gone further, insisting everybody is defined by his or her identity and certain victim identities must be favoured.

My Times column on the overdone threat from robots:

The tech industry, headquartered in Silicon Valley, is populated largely by enthusiastic optimists, who want to change the world and think they can. But there is one strand of pessimism that you hear a lot there: that the robots are going to take all our jobs. With artificial intelligence looming, human beings are facing redundancy and obsolescence. I think this neo-Luddite worry is as wrong now as in Ned Ludd’s day.

My Times column on Trump's electoral triumph (originally published 14 November):

Years of compensating for the media’s tendency to look on the dark side of everything has taught me that it generally pays to seek silver linings. It’s possible of course that Donald Trump will start a culture war, a trade war and a nuclear war, but it’s also just possible that, while behaving like an oaf, he will preside over a competent administration. So here, after a few days of talking to people in America’s two biggest economies, California and Texas, are ten reasons why I think a Trump presidency may not be as awful as many think, even if, like me, you heard the news of his victory with a sinking feeling.

1 Just as after Brexit, the markets went up, not down. Virtually all analysts agreed that if Mr Trump won the stock market would fall — most estimates ranged from 2 per cent to 7 per cent. Instead the S&P 500 was up 3.8 per cent by the end of last week. The markets are betting that financial deregulation will encourage growth.

My Times column on the wisdom of crowds, published the day before election day in the US:

‘In these democratic days, any investigation into the trustworthiness and peculiarities of popular judgments is of interest.” So begins an article entitled Vox Populi, which is not about Donald Trump but was published in 1907 by Francis Galton, a pioneer of statistics, by then 85 years old. He had analysed the results of a sweepstake competition held at the West of England Fat Stock and Poultry Exhibition in Plymouth.

An ox was on display. Visitors could buy a postcard for sixpence and write their guess as to the weight of the ox, once slaughtered and dressed. Of 800 cards filled out, Galton rejected 13 as illegible and averaged the rest. The arithmetic mean of the 787 guesses came to 1,197lb. The true dressed weight of the ox was — yes — 1,197lb (Galton reported slightly different results, but recent reanalysis by Kenneth Wallis of Warwick University finds the match was exact).

My Times column on the surprising correlation between prosperity and improving conservation outcomes:

As foxes move into cities and deer, badgers and otters grow ever-more numerous, along with birds such as ospreys, buzzards and red kites, you might be thinking much of Britain’s wildlife is doing well. Yet last week the Zoological Society of London (ZSL), together with the World Wide Fund for Nature (WWF), published their latest assessment of the state of the world’s mammals, birds, reptiles, amphibians and fish: the Living Planet Report 2016. They found that on average populations of such animals declined by about 58 per cent between 1970 and 2012.

The report also provides evidence that while wildlife populations are doing poorly in poor countries, they are generally doing well in rich countries. I spent a happy few hours on virtual safari through the detailed database behind the findings (so I can report that granulated catfish in Paraguay are doing well, while grey-necked picathartes in Cameroon are doing badly), and this pattern emerges clearly.

My Times column on batteries:

Batteries are no longer boring. Whether catching fire in Samsung Note 7s, being hailed as the answer to future electricity grids thanks to breakthrough chemical innovation, or being manufactured on a gigantic scale in Elon Musk’s gigafactory in Nevada, batteries are box office. And though battery technology is indeed advancing by leaps and bounds, there is a considerable quantity of balderdash being talked about it too.

My recent Times column from 10 October on immigration and the European Union:

Michael Kosterlitz, one of the four British-born but American-resident winners of Nobel prizes in science this year, is so incensed by Brexit that he is considering renouncing his British citizenship: “The idea of not being able to travel and work freely in Europe is unthinkable to me.” He has been misled — not by Leavers but by Remainers.

It’s not just that the overseas press have consistently portrayed Brexit as a nativist retreat, despite Boris Johnson, Michael Gove and Daniel Hannan consistently saying the very opposite. Throughout the referendum campaign — and, shamefully, since — academics have been told by their lobby groups (such as Universities UK) that Brexit probably means losing access to European research funds, European scientific collaborations and European talent.

My recent Times column on the planning paralysis holding back Britain:

At last, the government is about to decide on a third runway at Heathrow airport — by the end of this month, I hear. It’s only been ten years since Tony Blair’s government first proposed the plan. Yet it will be three years until planning permission is granted and another six before the runway is finished. That’s two decades. Heathrow’s original three runways in 1946 took less than two years to build from scratch in a war-ravaged country depleted of funds and fuel. Why do such projects now take so inordinately long?

Land-use planning in Britain is not a joke; it’s a disgrace. The present system is grotesquely biased, not so much in favour of opponents or proponents of development, but in favour of delay and cost. I happen to think HS2 and Hinkley Point C are mistakes, but if I’ve lost those battles — and I probably have — then at least let’s get on and build them quickly, rather than spend the next decade paying lawyers and consultants to slow them down and inflate their costs.

I have sent the following letter to the president of the Royal Society and the Chairman and director of the Global Warming Policy Foundation in response to a highly misleading letter to me that was copied to them.

To Sir Venki Ramakrishnan FRS, Lord Lawson and Dr Benny Peiser

The text of a lecture given at the Royal Society on 17 October 2016:

(Note some minor corrections made subsequent to delivery. These are shown in italics.)

I gave a lecture recently at Haileybury College (the successor to the East India College where the economist Robert Malthus taught), on the topic of "The Misapplication of Malthus". It was based on a chapter of my book The Evolution of Everything:

Parson Malthus casts a long shadow over the past 200 years. He was a good man without a cruel bone in his body. But great cruelty has been done in his name and is still being done in his name. That’s the paradox I wish to explore this evening. 

Malthus’s finest legacy is to have sparked Charles Darwin into action. In September 1838, shortly after returning from the voyage of the Beagle, Darwin read, or re-read, Malthus’s essay on population and was struck by the notion of a struggle for existence in which some thrived and others did not, an idea which helped trigger the insight of natural selection. 

My Times column on free trade after Brexit:

The prime minister wants Britain to be “the most passionate, most consistent, most convincing advocate for free trade”. Under  either Donald Trump or Hillary Clinton, and with world trade stagnating, it looks as if the job is increasingly likely to be vacant in March 2019, so Britain has both a vital duty and a golden opportunity. It worked for us before.

Next year sees the 200th anniversary of David Ricardo’s insight of “comparative advantage” — the counterintuitive idea that trade benefits “uncompetitive” countries as much as efficient ones. If one country is better at making both cloth and wine than another, it can still pay it to get its wine, for example,  by making extra cloth to swap for the other’s wine. Or, as somebody once put it, even if Winston Churchill is a very good bricklayer (he was) it still makes sense for him to write books or run governments, and pay somebody else to build his walls.

My Times column on the Chan-Zuckerberg initiative in basic medical science:

Mark Zuckerberg, chief executive of Facebook, and his wife Priscilla Chan, a paediatrician, have announced their intention to spend $3 billion over ten years on medical research. Having met them last year, I thought I would take the liberty of making a suggestion as to how they spend their money.

My Times column on statins, snus and vaping:

One of the most salutary examples of people in authority getting risks wrong is a paper written in 1955 by the first head of the environmental cancer section of the US National Cancer Institute, Wilhelm Hueper. The title was “lung cancers and their causes” and he was absolutely convinced that “cigarette smoking is not a major factor in the causation of lung cancer”, because he thought this was a cheap shot by the chemical industry to divert attention away from pesticides.

We now know that smoking is a major cause of lung cancer, whereas pesticides are not. History is littered with example of experts being too reassuring about some risks, too alarmed about others. Washing hands between dissecting women who died in child birth and delivering babies? No risk, said the nineteenth century medical establishment, ostracizing Ignaz Semelweiss who had had the temerity to suggest otherwise. Dietary fats cause heart attacks, insisted the medical establishment for the best part of five decades till very recently. It was once the consensus that tonsils should be removed; no longer.

My essay on invasive species in the Wall Street Journal:

In July, the New Zealand government announced its intention to eradicate all rats, stoats and possums from the entire country by 2050 to save native birds such as the kiwi. It’s an ambitious plan, perhaps impossible to pull off with the methods available today, but it’s a stark reminder that invasive alien species today constitute perhaps the greatest extinction threat to animal populations world-wide.

Birdlife International, a charity that works to save endangered birds, reckons that of the 140 bird species confirmed to have gone extinct since 1500, invasive alien species were a factor in the demise of at least 71—an impact greater than hunting, logging, agriculture, fire or climate change.

My Times column on how the Arctic sea ice has melted in late summer before, between 10,000 and 6,000 years ago:

The sea ice in the Arctic Ocean is approaching its annual nadir. By early September each year about two thirds of the ice cap has melted, then the sea begins to freeze again. This year looks unlikely to set a record for melting, with more than four million square kilometres of ice remaining, less than the average in the 1980s and 1990s, but more than in the record low years of 2007 and 2012. (The amount of sea ice around Antarctica has been increasing in recent years, contrary to predictions.)

My Times column on economic libertarianism: 

Last week both Hillary Clinton and Donald Trump set out their economic policies in set-piece speeches. Mr Trump’s, delivered in Detroit, so far as one could tell from the fractured syntax and the digressions into invective, involves a trade policy designed to punish consumers and protect producers, a recipe for recession. But Mrs Clinton’s, also delivered in Michigan, was even worse. She too wants to pursue the old mercantilist fallacy of restricting imports and helping exports, but while spending more money, unleashing a blizzard of new regulations and doubling the minimum wage.

Never have the American people been faced with such paternalist, protectionist and authoritarian pair of options. The United States, long a beacon of economic libertarianism, is now being offered a choice between two forms of growth-killing, deficit-boosting, zero-sum, big-government economic nationalism. Long gone are the days when both Republicans and Democrats subscribed to some form of free-market economic philosophy while differing mainly over how to fight the cold war and the culture wars.

My Spectator article on the similarity between trophy hunting in Africa and grouse shooting in Durham. Both have huge benefits for non-target species of wildlife.

The vast Bubye Valley Conservancy in southern Zimbabwe is slightly larger than County Durham, as well as much hotter and drier. Yet both contain abundant wildlife thanks almost entirely to the hunting of game. In Bubye Valley, it’s lions and buffalo that are the targets; in the Durham dales, it’s grouse. But the effect is the same — a spectacular boost to other wildlife, privately funded.

My Times column on the history of opposition to innovation:

The prime minister is to announce today that she would like to redirect some of the future profits of shale gas production to households, rather than councils. This is eminently sensible. It gives local people a stake in the new technology; it recognises that innovation will only be accepted in society when its social effects are beneficial; and it reflects Theresa May’s philosophy that all of society should share in growth.

This is my Times column on why we are paying too much to decarbonise via both nuclear and renewables, but I have expanded various points to give detailed quotes from sources to verify my arguments. [The expansions are in square brackets and italics.]

If Hinkley Point C goes ahead, the cost for consumers of subsidizing it will be £30 billion, according to the National Audit Office, or five times what was originally estimated. The increase comes largely from the fact that fossil fuels are cheaper than even the lowest possibility envisaged by the late and unlamented Department of Energy and Climate Change.

[In 2012 DECC forecast three scenarios for fossil fuel prices. In the “high” scenario, the oil price, per barrel, in 2016 was expected to be $137.2; in the medium scenario, $119.2 and in the “low” scenario, $98.8. The price today is $43, that is less than half the lowest scenario envisaged by DECC just four years ago.]

My Times column on why experts get the future as wrong, or more so, than non-experts:

Michael Gove was mocked during the referendum campaign for saying that “I think people in this country have had enough of experts.” Critics asked pointedly if he dismissed the expertise of doctors when ill. But subsequent weeks have left economic experts, at least, looking a bit less than the full Nostradamus.

The expert pollsters told the hedge funds Remain would win right up till when it lost, so the pound and the FTSE 100 rose, then crashed. The expert financial forecasters then told investors the FTSE 100 would fall further, but it quickly recovered all its lost ground and more. The expert analysts told us we should watch the FTSE 250 plunge instead, but that has now returned to the level it was at a week before the referendum.

My Times column on industrial strategy:

In her first speech on the steps of 10 Downing Street Theresa May said that she intends to listen to those who “just about manage”, not to the wealthy and mighty. “When it comes to opportunity, we won’t entrench the advantages of the fortunate few.” Dead right: but how?

In pursuit of that objective she has signalled that she may favour an industrial strategy intended to help those areas that have it toughest. Some have interpreted this as a sign that markets are out of fashion and that government intervention is back. That certainly seems to be part of the thinking of her aide Nick Timothy and think-tank influences such as David Skelton. Mr Timothy says it is time that politicians “questioned the unthinking liberalism of the policies they support”. Greg Clark, the business secretary, says he is thrilled to take charge of a “new department charged with delivering a comprehensive industrial strategy”.

Damian Carrington in the Guardian has attempted to imply criticism of me for writing an email to the energy minister in the House of Lords to draw his attention to a new technology for emissions reduction as a byproduct of an innovative manufacturing process. I explicitly was not lobbying. I have absolutely no interest in the technology or the company, but I happened to meet them through a friend and thought their technology sounded interesting and the British government might be interested, since it might be a way for the UK to generate jobs and revenue while cutting emissions; the company was not asking for a subsidy. I met them over a drink – and I paid. I have acted entirely appropriately, and the Guardian article is trying to make a scandal where there is none.

The source of the Guardian article is a Freedom of Information Request from Friends of the Earth. The FoE individual quoted in the article is Guy Shrubsole, who has a criminal conviction for aggravated trespass as he prevented people getting to work at a surface coal mine in Northumberland on the Blagdon Estate. Mr Shrubsole was given a conditional discharge after pleading guilty to chaining himself to mining machinery to cause disruption at the site. He was also given a three year restraining order preventing him from coming within 50 metres of the mining company’s sites or offices. Mr Shrubsole appears to be under the mistaken impression that I was telling the energy minister about a carbon capture and storage technology. Even if I had been, there would be no scandal.

The real scandal is that the Guardian relies on a criminal as a source.

My Times column on the way social media polarises discourse and raises the political temperature: 

Schisms of hatred seem to be fracturing the political landscape wherever you look right now: the police versus the black community in America, Sunni v Shia, Wahhabism v the West, Trump v Hillary, Labour v itself, Brexiteers v Bremainers, climate “alarmists” v “deniers”. All are glaring at each other across cyber-chasms of flaming verbal magma.

My recent Times column on the herbicide glyphosate:

I once tried the organic alternative to the herbicide roundup for clearing weeds from garden paths: a flame-thrower. It was brutal for the environment, incinerating innocent insects and filling the air with emissions. Next week I might have to go back to that. Roundup, the world’s safest, cheapest and most effective weedkiller, may be illegal within days in Europe.

I published this column in the Times recently. Since then it has become clear that Britain will probably have a female prime minister soon (Theresa May and Andrea Leadsom are the bookies' favourites), and a female leader of the opposition (Angela Eagle ditto), as well as a female monarch. In Scotland all three main party leaders are women. America may have a female president next year. It seems timely to discuss whether women bring different skills to the top jobs in politics. I think they do, and for the better:

After an American political party at last picked a woman candidate for president, and after watching a television debate on Europe last week in which one male was surrounded by six females, including the presenter, the idea of women in power has just about ceased to be unusual. The number of women elected as president or prime minister in the world was three in the 1960s, then 5, 8, 24 and 25 in each succeeding decade – and it has already reached 30 in this half-finished decade. Slow, but steady progress.

So, a question: are women sufficiently different from men for this to make a difference? Yet another brain-imaging study, at Stanford University, has found neural differences between men and women. When two men co-operate on a task, one particular part of the brain lights up in each; when two women co-operate, a different part of the brain lights up in each. When a man and a woman co-operate, both brains light up less – but they still co-operate fine. Different, but not unequal, in other words.

Here are three articles on the Brexit referendum of June 2016.

My Times column on the European Union's failure to grow digital giants:

Last week I visited an island and stood among a crowd of puffins. If I turned my head I could see the lighthouse. If I looked up, the arctic terns were above my head. Yet I never left a gallery in Gateshead. How come? I was wearing a virtual-reality mask.

I have tried this “Oculus” technology once before, when visiting Facebook in California (which owns Oculus) and it is truly extraordinary to have an all-round, up-and-down view of the world depending on how you turn your head. All it involves is a special (Samsung) smartphone jammed into a pair of goggles.

My Times column on the threat from zika virus:

Cancelling the Rio Olympics would do little to slow the spread of the zika virus. That horse has already bolted: more than 60 countries and territories already have zika. It will soon be almost anywhere that its mosquito host lives. Now that the link with microcephaly is well established, becoming pregnant in any country with zika carries a small but real risk of birth defects for the baby.

In the 1970s, troubled by the risks of using pesticides, we took our eye off the fight against mosquitoes and the diseases they carry. Zika is just the latest evidence that we are paying a heavy price for that. Between 1947 and 1958 Brazil managed to eradicate the Aedes aegypti mosquito from the entire country, as part of a continent-wide campaign against yellow fever. Yet the effort was not maintained, so the mosquito returned and now flourishes in the favelas of urban Brazil as well as most of the warm parts of the world.

My Times comment on a new report on genetically modified crops:

The exhaustive and cautious new report from the American National Academies of Sciences, Engineering and Medicine leaves no room for doubt that genetically engineered crops are as safe or safer, and are certainly better for the environment, than conventionally bred crops.
