Some skeptics wonder why I bother pursing and documenting the problems with Lewandowsky et al 2012 and with the blog ShapingTomorrowsWorld. They figure that all skeptics now know the papers dismal failings, and it’s clear that Lewandowsky is unlikely to be grateful for the help.
But Lewandowsky exposes people higher up to awkward questions. Why do they fund work so unscientific? Why do they allow such hypocrisy and bias on a government funded publication? Are standards at the University of Western Australia (UWA) so low that they can’t find a Professor who understands the scientific method, and can reason without name-calling? Aren’t other statisticians at UWA concerned at what Lewandowsky is doing to the reputation of “UWA Statistics”? Finally, aren’t the scientists who missed out on ARC funding angry that our taxpayer funds are given instead to someone who apparently uses the funds to promote his personal political views, instead of in the pursuit of knowledge? (See: Lewandowsky gets $1.7m of taxpayer funds to denigrate people who disagree with him)
The abject incompetence is a gift to us. Rarely is a study so outrageously bad that people with no scientific background […]
The Lewandowsky view is Drilling into noise. The McIntyre response: Lewandowsky’s Fake Correlation
My favourite Lewandowsky line is: “We cannot get into the details here…”
McIntyre can and does in gory depth. He posts the equations, the code, the tables, everything. He graphs the residuals, and shows the “severe non-normality” of them. He tests the correlation and finds that the two most obvious fake responses heavily affect the results:
“Lewandowsky is absolutely off-base in his assertion that the examination of outliers is inappropriate statistical analysis. In fact, exactly the opposite is the case: proper statistical analysis REQUIRES the examination of outliers.”
“One can readily see that the two super-scammers (889, 963) contribute essentially 100% (over 100%) actually of the negative correlation between CauseHIV and CYMoon in this calculation.”
Lewandowsky says: “no one who has toyed with our data has thus far exhibited any knowledge of the crucial notion of a latent construct or latent variable.”
McIntyre replies: “Principal components, a frequent topic at this blog, are a form of latent variable analysis.”
As a former graduate of UWA, this is embarrassing. Does UWA not teach and use rigorous statistical methods? Is there no one who can help him?
Plus, when […]
Stephan Lewandowsky, Gilles Gignac, Klaus Oberauer
The scathing blog posts are popping up everywhere. From William Briggs we get a sense of the historical importance of the Lewandowsky et al effort. One day a terrific psychological study is going to be written on the madness and mass lunacy which arose after climate change swam into the public’s ken… The cornerstone of this future pathological report may well be the peer-reviewed Psychological Science paper “NASA faked the moon landing—Therefore (Climate) Science is a Hoax: An Anatomy of the Motivated Rejection of Science” by Stephan Lewandowsky, Klaus Oberauer, and Gilles Gignac, perhaps the completest, most representative work of its odd era. “Everything that could have been done wrong, was done wrong. Every bias that could have been manifested, was manifested. Every fallacy pertinent to the matter at hand was made. The conclusions, regurgitated from unnecessarily complicated statistical procedures, did not follow from the evidence gathered, which itself was suspect. In its way, then, the paper is a jewel, a gift to the future, a fundamental text to how easy it is to fool oneself. “ Steve McIntyre goes through the statistical tests, finds questionable practices, questions he can’t answer, and […]
Stephan Lewandowsky, Gilles Gignac, Klaus Oberauer
Stephen Lewandowsky’s paper, soon to be published in Psychological Science, appears to be drawn from one or two grants from the Australian Research Council that total nearly a million dollars (though it’s not entirely clear which grants apply to the paper).
“If you wonder, like I do, whether the Australian taxpayer gets value for money, ponder that somewhere a cancer researcher was denied funding in order for Lewandowsky to do his work”
One grant, which he shares with coauthor Dr Klaus Oberauer, was for $694,000 for research on “Keeping Memory Current: Updating and Discounting of Information“. Apparently it is of national benefit, because: “Basic research in psychology is of particular national benefit because the available national research funding is commensurate with the requirements of world-class research in psychology.” “World class” does not usually mean research based on a logical error with a sample too small to be statistically significant and using a self-selecting, unsecure, sample from sites that detest the research group. Aside from that, the sentence itself is circular bureaucratese-babble. What does it mean? Is he suggesting that research in basic psychology is useful because taxpayer funds are only given to world […]
Stephan Lewandowsky is rattled. Not surprisingly. Right now, his blog has gone from a steady run of zero-to-three-comment-posts up to 200, and the skeptics are armed with cutting questions.
But the more he writes, the worse it gets. Skeptics have picked apart his methods, his data, his transparency, and his conclusions. His latest responses are childish taunts with variants of name-calling. What place does an unrelated smear have in a science debate? It’s an effort to distract people.
His paper, in press, has been shown to have a misleading headline, with worthless conclusions based on statistically insignificant number of responses, using a clumsy one-sided test — the aim of which was obvious to most readers. When asked for data he provided answers to 32 questions but still hides the results obtained to a quarter of his original survey, including the basic demographics. He changed the order of questions depending on the blog he sought replies from — effectively putting different versions of the survey up (see below for his explanation). He himself emailed or was named in emails to alarmist anti-skeptic bloggers, while he used an unknown assistant to email skeptical blogs. These non-standard methods were not described in his […]
Steve McIntyre audited Stephan Lewandowsky’s data to weed out the obvious fake responses. That people would “game” the test was predictable given the clumsy nature of the survey, the one-sided nature of the conspiracies investigated, the virulently anti-skeptic sites where it was hosted, and the comments on the threads where it was announced. Obviously the survey hoped to show skeptics were nutters, and when it was posted in front of those who-hate-skeptics, readers obliged.
Steve McIntyre weighs in with a lengthy post, several original graphs, and concludes:
“Lewandowsky, like Gleick, probably fancies himself a hero of the Cause. But ironically. Lewandowsky’s paper will stand only as a landmark of junk science – fake results from faked responses.
As Tom Curtis observed, Lewandowsky has no moral alternative but to withdraw his paper.”
When the number of responses to conspiracies are graphed against the share that is “skeptical” of man-made global warming McIntyre reveals an interesting pattern. The “Oklahoma” point on the bottom right of the graph was the most popular conspiracy theory — but percentage-wise, “alarmists” were more likely to support this theory than so called “skeptics” were.
The line across the graph represents the proportion of the total responses which […]
Steve McIntyre weighs in:
“As others have observed, the number of actual respondents purporting to believe in the various conspiracies was, in many cases, very small. Only 10 respondents purported to believe in Lewandowsky’s* signature Moon Landing conspiracy. These included a disproportionate number of scam responses. Indeed, probably all of these responses were scams.
However, Lewandowsky’s statistical analysis was unequal to the very low hurdle of identifying these scam responses. Lewandowsky applied a technique closely related to principal components to scam and non-scam data alike, homogenizing them into a conspiratorial ideation.”
Josh is so quick these days :- ) Thank you Josh. An excellent job.
* Correction: “Curtis’s” should have been Lewandowsky.

9.8 out of 10 based on 49 ratings
What can I say? Prof Lewandowsky, expert in conspiracies, thinks we are postulating a conspiracy — but the bad news for him is that we are postulating straight out incompetence, no conspiracy required.
How does Lewandowsky define “conspiracy”? However he wants.
I hate to say I told you so, but I did. Back in May 2010, before Lewandowsky posted his survey, he foresaw the results:
“This attribute of conspiracy theorising applies in full force to the actions of climate “sceptics” who operate outside the peer reviewed literature” [ABC Drum]”
and I foresaw what he would do with them:
“Lewandowsky uses the name-calling to “poison the well” against people who don’t even believe in a conspiracy [about man-made global warming], but happen to also be skeptical…Jo Nova May 2010“
Graham at OnLine Opinion (OLO) has posted Part II of a Fish rots from the Head and it’s quite something to see.
This post will look at the question of what is a conspiracy, and also what constitutes “conspiracist ideation”. The conclusion, just to save you reading to the bottom, is that Lewandowsky has no clear idea so adapts it to what fits his thesis. This is […]
There were only ten positive responses.
There are many questions to be answered about this paper in “Psychological Science.“ Questions worth asking at all kinds of levels.
The authors, Lewandowsky, S., Oberauer, K., & Gignac, C. E., drew conclusions about skeptics by largely surveying alarmist sites. They got hardly any positive responses, some of which may have been faked (who can tell?). Then with a tiny ten positive responses out of 1147, the authors drew inferences about a group of people which must number between one hundred thousand to one million or more individuals. Worse, of the ten who thought the moon landing was faked, only three or four were skeptics. In the UPDATE below note that there appear to be three different forms of the survey, a point that surely needs some explanation.
The headline of the study “NASA faked the moon landing—therefore (climate) science is a hoax: An anatomy of the motivated rejection of science” is drawn from only those ten responses. Do I need to say it’s a sample size too small to draw any conclusions? I shouldn’t. But this point alone should have been enough for the paper in its current form to fail review, yet […]
I‘m putting on a conservative, understated hat. This could be the worst paper I have seen — an ad hom argument taken to its absurd extreme, rebadged as “science”.
Professorial fellow Stephan Lewandowsky thinks that skeptics who are “greatly involved” in the climate debate believe any kind of conspiracy theory, including that the moon landings never happened, that AIDS is not due to HIV, and that smoking doesn’t cause cancer. But he didn’t find this out by asking skeptics who are “greatly involved” in the climate debate or by reading their popular sites. He “discovered” this by asking 1,000 visitors to climate blogs. Which blogs? He expertly hunted down skeptics, wait for it… here:
Deltoid, Tamino Scot Mandia, Bickmore, A Few Things Ill Considered, Hot-Topic (NZ) Trunity (unconfirmed?) John Cook (through twitter, h/t Barry Woods at Climate Audit)
This is the point where the question has to be asked: Did Lewandowsky, Oberauer, and Gignac really think they would get away with it? Did none of the reviewers at “Psychological Science“ think to ask if the “sampling” of alarmist blogs would affect the results?
The paper is titled:
“NASA faked the moon landing — Therefore (Climate) Science is […]
What kind of organization receives all its funding from one source, then claims to be “independent?” (Yes, spot another GONGO idea).
The Conversation trumpets that it is “Independent” but it’s funded with $6 million from … the Government. As Tim Blair said “it’s a baby ABC“. (A Government organized “non government” organisation).
The Conversation gets 20,000 readers a day (apparently). According to the Alexa Stats, I single-handedly get about half the global traffic they do. They have an entire nation of university staff to help write stories. I’ve had ten guest authors and have written over 700 posts myself.
(If what they do costs $6 million, does that mean my site is worth $3m? Am I grossly underpaid, or are they grossly overpaid?)
This is another example of the self-growing-cycle of big-government. The site is dominated with stories that favor statist-big-government policies. They break laws of logic and reason, claim that experts are writing, but we non-experts working from home can point out the errors of those with professorships in our spare time, and with no PhD.
Consider the wit and wisdom of one Stefan Lewandowsky — who writes as a Professorial Fellow of a misnamed topic […]
“Climate denial and the abuse of peer review“
Can someone get Stephan Lewandowsky his medication? His new marketing message is that “deniers” don’t do peer review papers. There’s a curious case of acute-peer-review-blindness (APRB) occurring. It doesn’t matter that there are literally thousands of pages of skeptical information on the web, quoting hundreds of peer reviewed papers, by people far more qualified than a cognitive-psychologist, yet he won’t even admit they exist.
…most climate deniers avoid scrutiny by sidestepping the peer-review process that is fundamental to science, instead posting their material in the internet or writing books.
Dear Stephan, deny this: 900 papers that support skeptics. What is it about these hundreds of papers published in Nature, Science, GRL, PNAS, and Journal of Climate that you find impossible to acknowledge? (And do tell Stephan, if people need to publish peer reviewed material before they venture an opinion on climate science online, how many peer reviewed articles on climate science have you produced?)
Obviously, the real deniers are the people who deny the hundreds of papers with empirical evidence that show the hockey stick is wrong, the world was warmer, the climate changes, and the models are flawed.

Professor Stephan Lewandowsky may not understand much about the climate, but he is a professor of psychology — so satire, humor, and hoaxes ought to be right up his alley, right? He’s realized he fell for the brilliant Alene Composta (a master satirist) replying to her and even sending her fake request for advice to fellow blogger John Cook (who fell for it too).
Alene ticked all the headline stereotypical victim-leftie boxes, her interests included “christine milne”, “organic gardening” and “batik hangings” and lets face it, “Composta” is a red flag, rather. So she wrote to Lewandowsky begging for advice in dealing with monster commenters from Bolt and Blair, and notably pointed to him surviving my scorn and ridicule:
I recently began blogging, especially about climate change, and after a month my site was noticed. Noticed by the wrong people, sadly. Readers of Tim Blair and Andrew Bolt have swamped my site with genuinely abusive comments, many relating to my disability, which I find very hurtful.
So my question to you is this: How do you deal with monsters like this?
I have read and savoured every column you have published at Unleashed, and I have read the hateful comments […]
Stephan Lewandowsky reasons by bad-analogy
How do we know man-made climate change is a mortal threat? Some people discuss radiosondes, but for Lewandowsky, the answers lie in laser surgery, gravity waves, airplanes, bridges, AIDS, nanotechnology, falling apples, and driving cars into brick walls.
On Ad Hominem Unleashed (otherwise known as the ABC), Lewandowsky is working his way through the fallacies season by season — he’s tried argument from authority, he’s hailed expert opinion, and even pretended that expert opinion is evidence.
So now, moving right along into Spring, he’s come to a variation of the “insurance” argument. Having told us how absolutely certain everything is, with a straight face, he’s now telling us it’s uncertain, but basically, since we absolutely definitely know it might be bad, we ought to reject the best source of energy known to humankind, and try all the alternatives, no matter how uncertain they are, even if it kills people. (I’m sure he doesn’t think of it that way, but he might change his mind if he spent a day with a mother in Tanzania who can’t afford to boil drinking water and is nursing a child with typhoid.)
Follow his “thinking”
Lewandowsky is so ahead-of-the-pack […]
Once more the ABC is posting logical failures, confused non-evidence, and baseless thinking. This time Professorial Fellow Stephan Lewandowsky also tries to talk about economic cost benefits, without analyzing either costs or benefits, and doesn’t seem to know the difference between a free market and a fixed one. Why do they bother?
Lewandowsky says we should act — despite the supposed “lack of certainty”. Given that there are multiple studies and empirical evidence that suggests carbon has no catastrophic effect, what he is effectively saying is we should ignore the observations and be obedient to the Gods of “science” instead. It harks straight from our stone age tribal era.
Right from the outset, let’s be clear, that for all Lewandowsky’s bluster about the scientific evidence, he has never once posted any reference showing observational evidence that the touted positive feedback written into the models-of-doom has any basis in fact. As usual, he points to the Biblical “Consensus”, even though we’ve pointed out the basics of science (that consensus is an unscientific, illogical argument from authority, and is baseless in science). When the government has poured in billions to “find” a consensus, it would be flat out shocking if they couldn’t […]
Picasso-Brain-Strikes-the-Climate-Debate: Can't think. Can't reason.
Tomorrow night the University of Western Australia (UWA) is hosting “Climate change scepticism under the spotlight”, where people who ought to know better are reverting to stone age reasoning. “Hail the Gods of Science!” The shame, the shame, it’s my old university.
Australian Professorial Fellow Professor Stephan Lewandowsky, from UWA’s School of Psychology, will discuss the perils of ignoring consensus in science…
The UWA School of Science ought to be grovelling embarrassed. Any scientific professorial fellow ought to warn about the dangers of ignoring the empirical evidence, or the perils of missing the whistleblowers who point out logical flaws.
Can we add that up?
Let’s follow the reasoning on consensus science. How do you weight the scoring system? Is one post-doc worth 3 honors students, or 5? Do we dilute citation-value according to the number of authors on each paper? Does a Nobel peace prize winner trump a class of undergraduates? Quick, we need a committee to figure it out. I can feel the need for a emergency formation of the Scientific-Authority-Demarkation-Institute. UN based of course.
I have written many times about how Lewandowsky uses Argument from Authority ad nauseum along […]
This is too rich. Baa Humbug has found scientific peer reviewed research that skeptics are more attuned to reality and better able to discount misinformation (!) but, oh the irony, which researcher makes this claim? The man with the fairy dust logic, Stephan Lewandowsky. It’s just a shame he wouldn’t know a skeptic if one sat on him.
He presented his research conclusions in Nov 2007 in Online Opinion and The Canberra Times as A Sceptics Guide to Politics. One week later with a completely straight face, he implored everyone to act to save the climate, because it was obvious. Of course.
In his world, if you question officialdom and you’re “right”, you’re a skeptic, but if you question officials and you’re “wrong”, then you’re a denier. Got it? It all makes sense, but only if Lewandowsky is God. Somehow He knows when to trust the news-media and politicians: John Howard and George Bush couldn’t be trusted over Iraq, but obviously Kevin Rudd and Penny Wong are entirely correct on Climate Change. (After all, most of the world’s bankers agree with them.)
I recently conducted research with colleagues abroad in which we investigated how people processed information about Iraq. We […]
Ad hominem Unleashed on the ABC
On our ABC there’s lots of talk “about evidence” but next to nothing of actual evidence. (The empty homage to “evidence” is handy though, it keeps the pretense alive that it’s a scientific conversation). Stephan Lewandowsky is still doing his Picasso-brain-best to search in all the wrong places for enlightenment.
Is the planet warming from man-made CO2? Lewandowsky “knows” it is. Why? Because the 9/11 truthers are conspiracy theorists (and conspiracies are always wrong). O’ look, a few people ask odd questions about an accident in a building years ago, and sometimes those people are also the species Homo Sapiens Climata Scepticus (!). So it follows (if you are insane) that because some people still doubt the official story of an unrelated past event, man-made global warming will contribute 3.7W/m2 in the year 2079, and we’ll all become souffles in the global Sahara.
I’m not making this stuff up. I’ve tallied up the obvious errors from both articles. His power to confuse himself with red herrings is … “impressive”.
Lewandowsky scorecard for logic and reason
Argument from authority 4

Picasso-Brain-Strikes-the-Climate-Debate: Can’t think. Can’t reason.
Stephan Lewandowsky’s ABC article on climate change was headlined “Opinion Versus Evidence“. Then with dead-pan delivery, he lists the “evidence” but it’s all … opinions.
The question of “delusion” is looming. I mean really, is this a cry for help? There are not many laws of reason that Stephan leaves unbroken. He appeals to authority, attacks the “man”, and talks about everything bar the evidence on climate change. Is he serious? “Trust me” he says, the world is warming because AIDS is real, mass-murderer Ivan Milat was guilty, Lord Monckton is only a non-voting member of the House of Lords, a few skeptics are burko, 97% of paid climate scientists agree that we ought to be worried and keep paying them, and someone has discussed the actual money that climate scientists earn (how could they) and to top it off, the IPCC report is 3000 pages long (!).
Not to mention that Google Scholar (“I’m so technical”) finds lots of hits (thanks to Vice President Al Gore who arranged for the US Government to pay billions of dollars to his favorite researchers, and who also is on the Google advisory team), plus the world […]
Some scientists just keep looking in the wrong places for answers. Here’s Stephan Lewandowsky, professorial fellow of psychology, in The Age trying to answer the most important question in modern science and economics. He refers to ClimateGate and asks if the stunning accusations of serious misconduct are true? Watch the flat out assertion backed by a non-sequiteur:
They are not. Even if we presume that the stolen material is authentic, the notion that climate data is being nefariously withheld is fantastical.
This does not even make sense within the confines of it’s punctuation. Is there a new Natural Law of Thermodynamics that says it’s impossible to withhold data? The data is gone, even Phil Jones, head of the East Anglia Climate Research Unit admits he has withheld it and won’t ever provide it:
“The two MMs have been after the CRU station data for years. If they ever hear there is a Freedom of Information Act now in the UK, I think I’ll delete the file rather than send to anyone.”
We know the emails are real. Phil Jones has said as much. He admits he has withheld data for years, and that he’ll delete it as well […]
