I've known about this effect for a while as I've been variously accused of being in the pocket of big pharma, big ag, big science, democrats and republicans etc. Now Stephan Lewandowsky, in follow up to his "NASA Faked the Moon Landings – Therefore (Climate) Science is a Hoax." paper, has used these conspiratorial responses to study how conspiracy theorists respond to being studied! It's called "Recursive fury: Conspiracist ideation in the blogosphere in response to research on conspiracist ideation".

Here's the abstract:

Conspiracist ideation has been repeatedly implicated in the rejection of scientific propositions, although empirical evidence to date has been sparse. A recent study involving visitors to climate blogs found that conspiracist ideation was associated with the rejection of climate science and the rejection of other scientic propositions such as the link between lung cancer and smoking, and between HIV and AIDS (Lewandowsky, Oberauer, & Gignac, in press; LOG12 from here on). This article analyzes the response of the climate blogosphere to the publication of LOG12. We identify and trace the hypotheses that emerged in response to LOG12 and that questioned the validity of the paper's conclusions. Using established criteria to identify conspiracist ideation, we show that many of the hypotheses exhibited conspiratorial content and counterfactual thinking. For example, whereas hypotheses were initially narrowly focused on LOG12, some ultimately grew in scope to include actors beyond the authors of LOG12, such as university executives, a media organization, and the Australian government. The overall pattern of the blogosphere's response to LOG12 illustrates the possible role of conspiracist ideation in the rejection of science, although alternative scholarly interpretations may be advanced in the future.

Awesome. It's actually a great paper, from the introduction discussing Diethelm and Mckee's work on conspiratorial ideation (who cited us in their original paper), to the comparisons between censorship accusations by diverse anti-science movements from the tobacco/cancer denial to HIV/AIDS denial, Lewandowsky et al., lay the groundwork for understanding this problem as a fundamental characteristic of all anti-science. They even cite a book chapter in which the authors make the link that conspiracies are specifically used to rhetorically challenge science when one lacks adequate data (Lahsen, M. (1999). The detection and attribution of conspiracies: the controversy over Chapter 8. In G. Marcus (Ed.), Paranoia within reason: a casebook on conspiracy as explanation (pp. 111{136). Chicago: University of Chicago Press.) I'll have to look that one up, as that was our primary conclusion about denialism when we started writing about it in 2007.

The authors then go on to the conspiracist reaction to their original paper:

When the article by Lewandowsky et al. became available for download in July-August 2012, the climate denialist blogosphere responded with considerable intensity along several prongs: Complaints were made to the rst author's university alleging academic misconduct; several freedom-of-information requests were submitted to the author's university for emails and documents relating to LOG12; multiple re-analyses of the LOG12 data were posted on blogs which purported to show that the eects reported Recursive fury 8 by LOG12 did not exist; and a number of hypotheses were disseminated on the internet with arguably conspiracist content. This response is not altogether surprising in light of research which has shown that threats - in particular to people's sense of control - can trigger targeted small-scale conspiracy theories (Whitson & Galinsky, 2008), especially those involving a specic opponent (Sullivan, Landau, & Rothschild, 2010).

So what does any good scientist who is interested in the empirical study of conspiracy theories do in such a situation? Mine it for data!

The remainder of this article reports a content analysis of the hypotheses generated by the blogosphere to counter LOG12. The extent and vehemence of contrarian activity provided a particularly informative testbed for an analysis of how conspiracist ideation contributes to the rejection of science among web denizens. Unlike previous analyses of web content, the present project was conducted in real time" as the response to LOG12 unfolded, thus permitting a fine-grained temporal analysis of the emerging global conversation.

Using google alerts and other strategies they tracked the response to their paper throughout the denialsphere, then evaluated them using 6 criteria to judge whether the author used conspiracist tendencies independent of actual content. These criteria were great, and as I read them I couldn't help thinking it is really a beautiful summary of the aberrant thought processes of the conspiracist. They were (1) assuming nefarious intent (NI) on the part of their opponent, (2) delusions of persecution including Galileo comparisons (persecution/victimization or PV) -awesome-, (3) a "nihilistic degree of skepticism"/paranoid ideation (NS), (4) an inability to believe in coincidence or "not an accident" (NoA) thinking, (5) toleration of inconsistencies and contradictions in their own counter-hypotheses as long as they challenge the "official" version (or Must-Be-Wrong MbW), and (6) the incorporation of contrary evidence as further evidence of a conspiracy thus "self-sealing" their hypothesis (SS). This is a really brilliant break down of the behavior if you ask me in particular number 6 which they even provide the perfect example of:

Concerning climate denial, a case in point is the response to events surrounding the illegal hacking of personal emails by climate scientists, mainly at the University of East Anglia, in 2009. Selected content of those emails was used to support the theory that climate scientists conspired to conceal evidence against climate change or manipulated the data (see, e.g., Montford, 2010; Sussman, 2010). After the scientists in question were exonerated by 9 investigations in 2 countries, including various parliamentary and government committees in the U.S. and U. K., those exonerations were re-branded as a whitewash" (see, e.g., U.S. Representative Rohrabacher's speech in Congress on 8 December 2011), thereby broadening the presumed involvement of people and institutions in the alleged conspiracy. We refer to this "self-sealing" criterion by the short label SS.

At denialism blog we've been describing these tactics for years, in particular I feel like the Crank Howto seems to incorporate most of these denialist tactics. In particular, that the authors recognized the persecution complex of the conspiracist is heart warming.

For the meat of the study, the authors then go through the evolution of reactions to their paper, and it's fascinating. Starting with lots of allegations of "scamming" (must be wrong) and a smear to make them look like nutters (persecution victimization) the conspiracy theories then evolved about everything to whether or not the authors didn't actually contact skeptic blogs (amazingly the blogs they did contact came out and appear to have lied about not being contacted), persecutorial delusions about the authors blocking individual skeptics IP addresses from accessing the paper (and further conspiracies that when they are being unblocked it's just to make them look paranoid), conspiracies about it being a ploy by the Australian government (nefarious intent), and it gets crazier and crazier from there. One of the most fascinating aspects of the evolution of the response was how, predictably, as more information was made available, rather than quashing conspiracies, the conspiracy theorists would just broaden the nefarious actors to larger and larger circles of foes:

Second, self-sealing reasoning also became apparent in the broadening of the scope of presumed malfeasance on several occasions. When ethics approvals became public in response to an FOI request, the presumption of malfeasance was broadened from the authors of LOG12 to include university executives and the university's ethics committee. Similarly, the response of the blogosphere evolved from an initial tight focus on LOG12 into an increasingly broader scope. Ultimately, the LOG12 authors were associated with global activism, a $6 million media initiative, and government censorship of dissent, thereby arguably connecting the response to LOG12 to the grand over-arching theory that "climate change is a hoax." Notably, even that grand "hoax" theory is occasionally thought to be subordinate to an even grander theory: one of the bloggers involved in the response to LOG12 (cf. Table 1) considers climate change to be only the second biggest scam in history. The top-ranking scam is seen to be modern currency, dismissed as "government money" because it is not linked to the gold standard

And doesn't that bring this back beautifully, full-circle, to the author's original hypothesis in the first paper that free-market extremism is behind global warming denialism?

Finally the authors discuss implications for science communication, and, unlike most people, I think they actually understand the problem. That is, you can't fix this problem with more communication, and more data. The nature of the conspiracy theorist is that all additional data and all contradictory data will only be used to demonstrate further evidence of conspiracy, that the conspiracy is even larger, or that the data are fraudulent. The "self-sealing" nature of the conspiracy theory, as the authors describe it, makes it fundamentally immune to penetration by logic, reason, or additional information.

Implications for science communication. A defining attribute of conspiracist ideation is its resistance to contrary evidence (e.g., Bale, 2007; Keeley, 1999; Sunstein & Vermeule, 2009). This attribute is particularly troubling for science communicators, because providing additional scientific information may only serve to reinforce the rejection of the evidence, rather than foster its acceptance. A number of such "backfire" effects have been identified, and they are beginning to be reasonably well understood (Lewandowsky, Ecker, Recursive fury 37 et al., 2012). Although suggestions exist about how to rebut conspiracist ideations|e.g., by indirect means, such as affirmation of the competence and character of proponents of conspiracy theories, or affirmation of their other beliefs (e.g., Sunstein & Vermeule, 2009) we argue against direct engagement for two principal reasons.

First, much of science denial takes place in an epistemically closed system that is immune to falsifying evidence and counterarguments (Boudry & Braeckman, 2012; Kalichman, 2009). We therefore consider it highly unlikely that outreach efforts to those groups could be met with success. Second, and more important, despite the amount of attention and scrutiny directed towards LOG12 over several months, the publication of recursive hypotheses was limited to posts on only 24 websites, with only 13 blogs featuring more than one post (see Table 1). This indicates that the recursive theories, while intensely promoted by certain bloggers and commenters, were largely contained to the "echo chamber" of climate denial. Although LOG12 received considerable media coverage when it first appeared, the response by the blogosphere was ignored by the mainstream media. This confinement of recursive hypotheses to a small "echo chamber" reflects the wider phenomenon of radical climate denial, whose ability to generate the appearance of a widely held opinion on the internet is disproportionate to the smaller number of people who actually hold those views (e.g., Leviston, Walker, & Morwinski, 2012). This discrepancy is greatest for the small group of people who deny that the climate is changing (around 6% of respondents; Leviston et al., 2012). Members of this small group believe that their denial is shared by roughly half the population. Thus, although an understanding of science denial is essential given the importance of climate change and the demonstrable role of the blogosphere in delaying mitigative action, it is arguably best met by underscoring the breadth of consensus among scientists (Ding, Maibach, Zhao, Roser-Renouf, & Leiserowitz, 2011; Lewandowsky, Gignac, & Vaughan, 2012) rather than by direct engagement.

Don't argue with cranks. I can't agree more. And historically this is what has worked with denialist groups. You don't debate them as if they're honest brokers, you treat them as the defective brains that they are, and eventually, their influence dwindles, and they'll be reduced to a small community of losers sharing their delusions of grandeur and righteous indignation in some tiny corner of the internet.

The key to preventing denialism isn't in arguing with those that have already formed fixed, irrational ideas. It can only happen with prevention - early education that emphasizes logic, scientific methods, rational thought and non-ideological, pragmatic approaches to problem solving.
