As CA readers are aware, Stephan Lewandowsky of the University of Western Australia recently published an article relying on fraudulent responses at stridently anti-skeptic blogs to yield fake results. In addition, it turns out that Lewandowsky misrepresented explained variances from principal components as explained variances from factor analysis, a very minor peccadillo in comparison. In […]

Lewandowsky’s most recent blog post really makes one wonder about the qualifications at the University of West Anglia Western Australia. Lewandowsky commenced his post as follows: The science of statistics is all about differentiating signal from noise. This exercise is far from trivial: Although there is enough computing power in today’s laptops to churn out […]
Is Lewandowsky et al 2012 (in press) replicable? Not easily and not so far. Both Roman M and I have been working on it without success so far. Here’s a progress report (on the first part only).
Conspiracy theorist Stephan Lewandowsky, in keeping with SkS style, has rewritten the history of his blog hosted by the University of Western Australia. Tom Fuller, who does online commercial surveys for a living, has sharply criticized the Lewandowsky’s tainted methodology – a methodology that relied on fake data to yield fake results. Over the past […]
Anthony has posted up an online census of participants in the Lewandowsky survey. I urge any readers who participated in the Lewandowsky survey to identify themselves as Anthony’s thread using their regular internet handle.
Lewandowsky et al stated that “links were posted on 8 blogs (with a pro-science science stance but with a diverse audience”. Lewandowsky identified the eight blogs (in an email to Barry Woods) as: Skeptical Science, Tamino, Bickmore, the UU-UNO Clmate Change Task Force (trunity), Ill Considered, Mandia, Deltoid and Hot Topic. The relevant posts at […]
Some information from sources at the University of Western Australia. On October 21, 2010, the following email was sent to the UWA staff mailing list: UWA researcher Charles Hanich is seeking participants for a web-based survey of attitudes towards climate science (and other sciences) and skepticism. The survey carries no risks for participants. To participate […]
Lewandowsky has stated that an online survey by an opponent was “useless” “without the authors demonstrating the integrity of their data” and that their study “should not have been published without the authors demonstrating the integrity of their data—I doubt that they could”. Words that apply even more forcibly to his own study. I guess […]
The key issue for Lewandowsky et al 2012 is its use of fake data, a problem squarely addressed by Tom Curtis of Skeptical Science and discussed at CA here. I raised this issue in a comment at Lewandowsky’s blog here as follows: Rather than answer the question, Lewandowsky, the author of a paper entitled “NASA […]
In Lewandowsky’s original editorial about climate “skeptics”, as discussed yesterday, Lewandowsky characterized climate skeptics as “obsessively yelping” and marked by the following belief: The further fact that the satellite data yield precisely the same result without any surface-based thermometers is of no relevance to climate “skeptics.” A few days ago, Lucia wondered about the identity […]
