The Mail on Sunday's own goal for delusionism

John Quiggin75 Comments

I’ve been struck by the fairly straight reporting of the IPCC Working Group 1 report on the physical science of climate change. Even Graham Lloyd at the Oz could find only one para for delusionist Benny Peiser[1] in his report, headlined “Science solid on global warming, IPCC declares“. What happened to the much anticipated delusionist counterattack?

I think we have the Daily Mail to thank for the no-show. As readers will recall, the Mail ran a story by David Rose under the headline “‘World’s top climate scientists confess: Global warming is just HALF what we said”. This was obviously absurd, and the Mail was forced to retract, but not before the story had been circulated throughout the denialosphere, notably including Bolt, the Oz, and the Torygraphs (both UK and Oz). The Oz eventually retracted, but Bolt didn’t bother. This misfire made it pretty much impossible to get much traction out of the modest adjustments that were actually contained in the report, such as reducing the lower bound estimate of climate sensitivity to 1.5 degrees (it was increased from 1.5 degrees to 2.0 degrees in the Fourth Assessment Report0

What’s interesting here is the fact that such obvious nonsense as Rose’s article got such a credulous reception. The idea that estimates of warming since 1950 could be out by a factor of two, or that a few years of additional data could change them substantial is entirely implausible, and a “confession of error” unsupported by a quote ought to raise alarm bells. Multiple levels of stupidity are needed to explain this. First, the majority of delusionists are simply innumerate, and ignorant of the most basic facts about data (we saw this with the claims about “no significant warming” since 1993). Second, the confirmation bias that affects everyone is magnified to a pathological extent in the parallel universe created by the right. Third, the tribal character of the movement means that there are no incentives to correct error. Presumably there are at least some delusionists who must have thought the “confession of error” story too good to be true. But no one would have thanked them for raising doubts. Whereas real climate scientists disagree vigorously among themselves (though all but a handful agree that the evidence for the basic fact of human-caused climate change is overwhelming), “sceptics” never criticise any claim on their own side, however absurd.

Most obviously, Judith Curry who was quoted in Rose’s article (not as a source for the bogus claims) must have realised it was nonsense. But she implicitly endorsed it, after its publication, but before its retraction. Note that, while saying the article quoted her accurately and would not be welcomed by the IPCC, Curry carefully avoids mentioning taking a position on its main claim, which she must have known to be false (she mentions the dispute briefly, at the bottom of here post, but offers no opinion). This is fairly typical of her, and her role-model Richard Lindzen.

But in this case, it was too clever by half. A smart delusionist if one existed would have jumped on Rose’s error and used it to build up some credibility for the future.

fn1. Peiser is, or was, a social anthropologist, and, according to Wikipedia, is currently a visiting fellow (not a real job, I suspect) at the University of Buckingham (definitely not a real university[2]). He’s therefore eminently qualified to represent the delusionist viewpoint on issues of physical science and the interpretation of statistical evidence.

fn2. To be boringly clear, I’m fully aware that Buckingham is an accredited institution with lecturers, degrees and so on, legally entitled to call itself a university. It’s still not a real university.

The global party of stupid (slightly updated)

John Quiggin42 Comments

The new conservative ministry has just been sworn in, and while it includes Ministers for Border Protection (that is, stopping refugees) and Sport, and even a minister for the centenary of the Anzac landings on Gallipoli in 1915, there are no longer ministers for science or higher education[1]. This is part of a fairly consistent pattern. The US Republican Party recently vetoed the creation of an unpaid position of National Science Laureate. In Canada, the Harper government eliminated the position of National Science Advisor, among many other anti-science moves. All of this reflects the inconvenient fact that scientific research often reaches conclusions that conflict with the policy preferences or religious beliefs of rightwingers.

It’s striking in this context to recall that, only 20 years ago, the phrase “Science Wars” was used in relation to generally leftish postmodernists in the humanities, who were seen as rejecting science and/or promoting pseudoscience (while some of this stuff was rather silly, there’s no evidence that it ever did any actual harm to science). These days postmodernist and related “science studies” critiques of science are part of the rightwing arsenal used by Steven Fuller to defend creationism and by Daniel Sarewitz on climate science. The routine assumption that the analyses put forward of innumerate bloggers are just as valid as (in fact more valid than) as those of scientists who have devoted their life to the relevant field is one aspect of this, as is the constant demand to “teach the controversy” on evolution, climate science, wind turbine health scares, vaccination and so on.

In the short run, the costs of attacking science are small. Scientists aren’t that numerous, so their conversion into one of the most solidly anti-Republican voting blocs in the US has’t had much electoral impact. But, eventually the fact that conservatives are the “stupid party” gets noticed, even by rightwingers themselves.

One person who has just noticed is Frank Furedi, a leading figure in the former Revolutionary Communist Party which, over the course of the 1990s, morphed into the rightwing libertarian Spiked group. In retrospect, Furedi jumped ship at the high water mark of right wing intellectual confidence, symbolised by Tom Friedman’s bloviations in The Lexus and the Olive Tree. Then came the Asian crisis, successive financial crises in the US and the intellectual debacle of climate delusionism, to which Furedi and the Spiked Group contributed actively. So, having joined what seemed to be the smart set, Furedi has finally realised that he is inescapably enmeshed in stupid. The result is this cri de coeur, lamenting the way in which rightwingers are called out for saying stupid things (he name-checks Tony Abbott, Stephanie Banister and, of course, Sarah Palin). Furedi doesn’t deny that rightwingers embrace stupidity, in fact he concedes it, observing

Not surprisingly, many conservatives become defensive when confronted with the put-downs of their intellectual superiors. Consequently, in many societies, particularly the US, they have become self-consciously anti-intellectual and hostile to the ethos of university life. Anti-intellectualism works as the kind of counterpart to the pathologisation of conservatism. And of course, the bitter anti-intellectual reaction of the right, which sometimes seems to affirm ignorance, only reinforces the smug prejudices of the intellectuals who see themselves as being morally superior. (emphasis added)

A couple of things are interesting about Furedi’s piece. First, he erases from history the period of rightwing intellectual dominance that began with the rise of market liberalism in the mid-1970s, and reached its apogee in the mid-1990s, before declining catastrophically in the Bush era. Second, he fails to recognise the way in which the silly-clever pointscoring of rightwing intellectuals like himself has contributed to the anti-intellectualism he deplores on his own side.

Even now, the intellectual collapse of the right has not had much effect on political outcomes. The dead ideas of the right shamble on in zombie form, and still dominate the thinking of the political class, particularly at the level of unconscious reflex. And, even to the extent that rightwing claims about, say, the beneficence of the financial sector, are discredited, the political power of the dominant class ensures that not much can be done. Winning the battle of ideas is a necessary, but not sufficient condition for progress. The rightwing embrace of stupidity is already doing them harm and will do a lot more in futer.

fn1. There are also very few women, but that needs another post.

What is it like to be a bug?

John Quiggin50 Comments

According to Calvin, at least, the same as to be a bat. But for the rest of us, it seems obvious that there is likely to be a qualitative difference between the subjective experience (if any) of a bug, and that of a bat. And, if true bugs don’t work for you in this example, there’s always the colloquial “bugs” such as bacteria and viruses, which presumably don’t have any experience at all.

The obesity paradox paradox (crossposted at Crooked Timber)

John Quiggin26 Comments

I see lots of stories made up of handwringing over the “obesity paradox”, normally presented as saying that even though obesity is a risk factor for all kinds of diseases, obese people appear to have lower mortality than others. A typical finding is the one reported here

being overweight or slightly obese was linked to about a 6 percent lower risk of dying, compared to people considered “normal weight. Being severely obese, however, was still tied to an almost 30 percent higher risk of death.

People are tying themselves in knots over this, but it doesn’t seem to me that there is any paradox to be explained. The obvious reading of the data is that the Body Mass Index[^1] ranges used for the various categories (20-25 Normal, 25-30 Overweight etc) were set a bit too low when they were originally estimated, or rather, guessed. From my quick look at the data, if you bumped the ranges up by a couple of points, the paradox would disappear. People at the bottom of the current normal range, who tend to have high mortality, would be classed as underweight, while those currently classed as slightly overweight would be reclassified as normal.

Am I missing something?

[^1] This point is logically separate from the general problems of the BMI, regarding muscle mass and so on.

The arithmetic of space travel (crossposted from Crooked Timber)

John Quiggin110 Comments

There’s been a lot of excitement about the discovery of two Earth-like[^1] planets, a mere 1200 light years away. Pretty soon, I guess, we’ll be thinking about sending colonists. So, I thought it might be worthwhile to a little bit of arithmetic on the exercise.

I’m going to assume (generously, I think) that the minimum size for a successful colony is 10 000. The only experience we have is the Apollo program, which transported 12 astronauts to the Moon (a distance of 1 light second) at a cost of $100 billion or so (current values). So, assuming linear scaling (again, very generously, given the need to accelerate to near lightspeed), that’s a cost of around $100 trillion per light-second for 10 000 people. 1200 light-years is around 30 billion light-seconds, so the total cost comes out roughly equal to the value of current world GDP accumulated over the life of the universe.

Even supposing that technological advances made travel possible over such distances possible, why would we bother. By hypothesis, that would require the ability to live in interstellar space for thousands of years. A civilisation with that ability would have no need of planets.

[joke alert on] On behalf of my fellow Australians, I’m going to make a counter-offer. For a mere $10 trillion, we can find you an area of land larger than a typical European country, almost certainly more habitable than the new planets, and much closer. We’ll do all the work of supplying water and air, build 10 000 mansions for the inhabitants and guarantee a lifetime supply of food. I’m hoping for a spotters fee of 0.01 per cent.[joke alert off]

On a related point, what should we be wishing for here? The fact that no-one has sent a detectable signal in our direction suggests that intelligent life forms similar to humans are very rare. If habitable planets are very rare, then this is unsurprising – interstellar distances preclude both travel and any kind of two-way communication. If on the other hand, the emergence of intelligent life is common, then the evidence suggests that its disappearance, through processes like nuclear war, must also be common.

Crusader Monckton

John Quiggin119 Comments

Ever since the Brisbane Institute cancelled my invitation to debate Christopher ‘Lord” Monckton a few years ago, I’ve followed his career with more than usual interest. His ‘Loony Lord M’ character, owing a lot to Screaming Lord Sutch, has been a huge hit here in Australia. By contrast, back in the UK, officials of the House of Lords have taken offence at his claims to be a member of that institution[1]. Some sniffy British Tories also seem to be upset by the claim that the UK government, along with Obama, Merkel and Gillard, are plotting to introduce a communist world government through a $20/tonne tax on CO2, and, of course, Agenda 21. Here in Australia, though, the fans love him for his ability to make the most absurd claims with a (sort of) straight face.

Given his obvious similarities to Sacha Baron-Cohen, it seemed reasonable to expect that Monckton would come up with a new character to keep his Antipodean fans amused. That expectation was proved correct when he turned up in Canberra as Crusader Monckton, endorsing pastor Danny Nalliah’s campaign against the oppressive rule of Shariah law in Australia, and the establishment of a new Judaeo-Christian political party. So far he’s getting rave reviews in advance press.

I’m a bit disappointed, though, that he doesn’t seem to be growing as an artist. Instead of making a clean break, he’s playing it safe, maintaining the previous climate delusionist shtick in parallel with the new one. And there isn’t really a lot of distance between the old character and the new one. Existing fans like Abbott, Albrechtsen, Bolt and, of course, Gina Rinehart will welcome the addition of the new Crusader persona, but there’s no way he can reach new audiences with such tired stuff. He really needs something more creative, like a campaign against gravity, or a claim that cancer is good for you.

Still, for those interested here’s the tour schedule

fn1. He ran at the first opportunity, receiving no votes. In emulation of the Monty Python Silly Party, he ran again, getting twice as many.

Problems with probabilities

John Quiggin53 Comments

Peter Hartcher is an insightful commentator on political issues, but we are all prone to fallacious reasoning about probability, and this article about Australian views of the US election illustrates quite a few of them. I don’t mean to pick on Hartcher, whose errors here are trivial compared to the practice of deriving strong conclusions from trivial fluctuations in poll numbers, but this is, as they say, a learning opportunity. Hartcher notes that most Australians, like most people everywhere outside the US, would prefer Obama and goes on to say

But Australians’ answers to another poll question on the US election were troubling. Asked which candidate they expect to win, 65 per cent name Obama and only 9 per cent Romney in the poll conducted by UMR Research.

This is not a question about preferences but expectations. And it is far removed from the realities in the US. The contest for the presidency is finely balanced.

The average result of eight leading polls of US voting intentions shows 46.9 per cent of Americans support Obama and 45.5 per cent Romney, according to realclearpolitics.com. That’s a difference of just 1.4 percentage points, which is within the margin of polling error. For statistical purposes, it’s a dead heat.

”Australians could be in for an unpleasant surprise on November 6,” the UMR Research pollster Stephen Mills observes.

Big tobacco loses again

John Quiggin84 Comments

Until relatively recently, Big Tobacco appeared invincible. Despite the fact that tobacco smoke was full of known carcinogens that would have had a factory shut down if they came out of the smokestack, and ample evidence that exposure to tobacco smoke caused cancer, not to mention the violation of liberty associated with blowing smoke in public places, Big Tobacco effectively resisted even the mildest restrictions on its activities. It was aided by a team of scientists and other “experts” willing to claim that the hazards of smoking were non-existent or overstated (notable names here include Enstrom & Kabat, Gio Batta Gori, Richard Lindzen, Steve Milloy, Fred Seitz and Fred Singer – Google has details).

Virtually all the main rightwing thinktanks in the US and Australia went along with this fraud (AEI, Cato, Centre for Independent Studies, CEI, Heartland and IPA among many others). While they might legitimately have argued part of their case on strict libertarian grounds, that would not have been sufficient to resist restrictions on passive smoking. So, they published attacks on science which any reasonable assessment would have shown to be false. In doing so, of course, they encouraged people to take risks with their own lives and those of others, while happily accepting money from the merchants of death. Whether they were knowingly lying, or merely recklessly indifferent to the truth, this episode should have discredited them forever (it certainly has with me).

But the tide has turned. US litigation in the 1990s exposed a treasure trove of internal documents which eventually led to racketeering convictions for the main tobacco companies. And now the High Court has rejected Big Tobacco’s (legally preposterous) challenge to plain packaging legislation in Australia, made on the supposed basis that it represented a taking of intellectual ‘property’. Not satisfied with one preposterous claim, the tobacco companies are planning another, having bribed the government of Ukraine to make a WTO accusation of trade restraint. Actually, this is a good thing. This case is such an obvious abuse of process, and the litigants so clearly evil, that the WTO will surely not be crazy enough to support their case. In rejecting it, they will probably be forced to set precedents that make future interference with domestic health policy more difficult.

Coming to the policy merits, the current legal status of tobacco is, in my view, a pretty good model for drugs in general – legally available, but with all kinds of promotion prohibited and with an active public health campaign to give accurate information on the associated risks.

Greenpeace, an enemy of science

John Quiggin139 Comments

Tim Lambert comments on Greenpeace sabotage of a CSIRO experiment on GM crops. Sadly, Greenpeace has become an openly anti-science organisation.

I agree with everything Tim says, but I’d add something more on the politics of this action. This kind of criminal vandalism, in the “right” cause, appeals to the juvenile instincts that nearly all of us retain to some extent, but it has repeatedly proved disastrous for the left, and the environmental movement. It’s worth comparing this kind of action to civil disobedience protests, where people put themselves on the line and openly invite arrest. If these guys had any desire to promote genuine debate they would turn themselves in and defend their actions in open court.

Given the embrace of anti-science and anti-rational views by the political right, it is important that the left and the environmental movement should dissociate themselves entirely from this kind of action. It will be a long time before Greenpeace can regain my support, if they ever do.
