Stephan Lewandowsky (born 3 June 1958) is an Australian psychologist. He has worked in both the United States and Australia, and is currently based at the University of Bristol, UK, where he is the chair of cognitive psychology at the School of Psychological Science. [2] His research, which originally pertained to computer simulations of people's decision-making processes, recently has focused on the public's understanding of science and why people often embrace beliefs that are sharply at odds with scientific evidence.

Education and career

Lewandowsky received his bachelor's degree from Washington College in 1980, followed by an M.A. in 1981 and a PhD in 1985, both from the University of Toronto. He served as an assistant professor of psychology at the University of Oklahoma from 1990 to 1994, and as associate professor for one year after that. In 1995, he joined the University of Western Australia, where he became the Winthrop Professor of Psychology in 2000. [3] He remained there until April 2013, when he joined the University of Bristol. [4] In 2014, he was named the first Digital Content Editor at the Psychonomic Society. [5]

In 2015, Lewandowsky was elected a fellow of the Committee for Skeptical Inquiry. [6]

Research

Correction of misinformation

Lewandowsky has published a number of studies examining people's belief in misinformation. In 2005, he was the lead author of a study which investigated people's beliefs in assertions about the Iraq War that had been retracted officially, and which examined people's beliefs about these assertions in Australia, the United States, and Germany. He and his co-authors found that American participants in the study persisted in believing the assertions even after being informed that they had been retracted. [7] Lewandowsky told the Wall Street Journal that the original misinformation already had become a part of the Americans' mental worldview by the time it was retracted. He also noted that "People who were not suspicious of the motives behind the war continued to rely on misinformation." [8] In 2012, Lewandowsky published an article in Psychological Science in the Public Interest which examined the literature on misinformation and efforts to correct it. [9] He found a considerable amount of speculation but little concrete research into the area. [10]

With John Cook, Lewandowsky wrote "The Debunking Handbook", [11] a review of research on debunking falsehoods and a guide to better practices for doing so. [12] Much of "The Debunking Handbook" focuses on "backfire effects", whereby telling people that they are wrong often reinforces their prior beliefs, rather than weakening them. An updated Debunking Handbook 2020 [13] tries to represent the consensus of the field.

Climate change and conspiracy theories

In 2012, Lewandowsky put forward what would later become one of his best-known studies regarding public opinion on climate change. The survey examined data from more than 1,000 readers of climate science blogs, taken from online questionnaires posted there. Lewandowsky approached five climate sceptic blogs to ask them to post the questionnaire, but they all declined to do so. [14] [15] The study was accepted by Psychological Science on 7 July 2012, and published in the May 2013 issue of the journal with the title, "NASA Faked the Moon Landing—Therefore, (Climate) Science Is a Hoax". Based on a survey of visitors to global warming related blogs, Lewandowsky and his two co-authors concluded that belief in free-market economics was associated with being more likely to reject not only the mainstream scientific view of global warming, but also the mainstream scientific position on whether HIV causes AIDS and whether tobacco smoking causes lung cancer. The study also concluded that believing in a "cluster of conspiracy theories"—such as that the FBI was responsible for the assassination of Martin Luther King, Jr.—was also associated with being more likely to reject the consensus view on global warming. [16]

Gary Marcus wrote that the paper's findings "fit in with a longer literature on what has come to be known as 'motivated reasoning.'" [17] The reaction to the paper from global warming sceptics was overwhelmingly negative, with Joanne Nova referring to it as "an ad hom argument taken to its absurd extreme, rebadged as 'science'." [18]

Later in 2013, Lewandowsky published another paper on a similar topic in Nature Climate Change . In that study, he and his co-authors told the study participants that 97% of climate scientists believe humans are causing global warming, and found that this significantly increased the proportion of people who believed it as well. They also reported that the effect was most discernible for those with free-market views. [19] [20] These findings contributed to what is now known as the Gateway Belief Model. Also in 2013, Lewandowsky and co-authors conducted another survey in which he examined the relationship between believing in conspiracy theories (such as 9/11 conspiracy theories) and rejection of various forms of science. They found that believing in such conspiracy theories was strongly associated with being more likely to reject all forms of science, such as climate change science, the safety of genetically modified foods, and the safety of vaccines. [21] [22]

"Recursive fury"

On 28 March 2013, Lewandowsky published "Recursive fury: Conspiracist ideation in the blogosphere in response to research on conspiracist ideation" in the journal Frontiers in Psychology . This paper described the reaction of climate change deniers to pre-publication versions of the "NASA Faked the Moon Landing—Therefore, (Climate) Science Is a Hoax" study that he had submitted to Psychological Science in 2012. His analysis found that, of the hypotheses generated by climate change deniers in response to his 2012 study, "many...exhibited conspiratorial content and counterfactual thinking." [23]

The Frontiers in Psychology journal received immediate complaints, and took the paper down while it carried out an investigation. [24] The paper was retracted with a notice published in March 2014, which stated: [25]

In the light of a small number of complaints received following publication of the original research article cited above, Frontiers carried out a detailed investigation of the academic, ethical, and legal aspects of the work. This investigation did not identify any issues with the academic and ethical aspects of the study. It did, however, determine that the legal context is insufficiently clear and therefore Frontiers wishes to retract the published article. The authors understand this decision, while they stand by their article and regret the limitations on academic freedom which can be caused by legal factors. [25]

Ars Technica reported that its questions were referred by the publishers to their lawyer, who told Ars: "Frontiers is concerned about solid science, and it's obviously a regret when you have to retract an article that is scientifically and ethically sound." Freedom of Information requests made by DeSmogBlog had obtained copies of the complaints, which included allegations of misconduct: some used legal terms such as "defamatory". [26]

Staff of the Australian Psychological Society wrote to Lewandowsky expressing concern "that some scientific journals feel sufficiently threatened by potential liability fears to not publish articles with 'inconvenient information' about climate change." [26] Elaine McKewon—who was one of the peer-reviewers of the Lewandowsky paper, in addition to being a research associate at the Australian Centre for Independent Journalism, University of Technology, Sydney [24] —said that she was "profoundly disappointed" by its retraction, and that, "Shortly after publication, Frontiers received complaints from climate deniers who claimed they had been libeled in the paper and threatened to sue the journal unless the paper was retracted." McKewon was quoted as saying that the journal had "caved in at the first pushback from the climate change denial community". [27] The Sydney Morning Herald reported that academics had described the retraction as having "a chilling effect on research". The University of Western Australia published the paper online after doing its own risk analysis; their lawyer, Kim Heitman, said that there was no reason to take it down.

After media reports about this retraction, the journal's Editorial Director Costanza Zucca and Executive Editor Fred Fenter made a joint statement on the journal's blog that "Frontiers did not 'cave in to threats'; in fact, Frontiers received no threats." The statement said that the main reason for retraction was insufficient protection for the rights of the studied subjects. [28] Ars Technica reported that this statement appeared to differ from the retraction notice, and according to one of the authors of the paper an anonymised version had been produced to meet the privacy concerns. Lewandowsky said that there had been a legally binding agreement on the original notice, and what he took "exception to is their latest statement, which is incompatible with the signed agreement and complete news to us". [29] The paper is available at the web page of the University of Western Australia. [30]

The paper was later republished in the Journal of Social and Political Psychology along with additional data, under the title "Recurrent fury: Conspiratorial Discourse in the Blogosphere Triggered by Research on the Role of Conspiracist Ideation in Climate Denial". [31] [32]

Perception of uncertainty

In May 2014, Lewandowsky published a two-part study on the relationship between uncertainty and the dangers of climate change, in which he argued that policymakers who argue that the scientific understanding of climate change is too uncertain to act are mistaken. Instead, the study argues that "on the contrary, uncertainty implies that the problem is more likely to be worse than expected in the absence of that uncertainty." [33] Lewandowsky told Salon that these studies showed that "uncertainty also increases the likelihood of exceeding 'safe' temperature limits and the probability of failing to reach mitigation targets." [34]

Global warming hiatus

A 2015 study by Lewandowsky, James Risbey, and Naomi Oreskes found that there is no substantive evidence of a global warming hiatus. [35]

Psychological features cluster identified

In its March 2019 edition, Scientific American published an article about his work that posited that people drawn to conspiracy theories share some psychological characteristics that may be clustered. [36] A secondary title to the article asserted: "Baseless theories threaten our safety and democracy. It turns out that specific emotions make people prone to such thinking".

<span class="mw-page-title-main">Conspiracy theory</span> Attributing events to secret plots instead of more probable explanation

A conspiracy theory is an explanation for an event or situation that asserts the existence of a conspiracy by powerful and sinister groups, often political in motivation, when other explanations are more probable. The term generally has a negative connotation, implying that the appeal of a conspiracy theory is based in prejudice, emotional conviction, or insufficient evidence. A conspiracy theory is distinct from a conspiracy; it refers to a hypothesized conspiracy with specific characteristics, including but not limited to opposition to the mainstream consensus among those who are qualified to evaluate its accuracy, such as scientists or historians.

A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research.

Misinformation is incorrect or misleading information. It differs from disinformation, which is deliberately deceptive and propagated information. Early definitions of misinformation focused on statements that were patently false, incorrect, or not factual. Therefore, a narrow definition of misinformation refers to the information's quality, whether inaccurate, incomplete, or false. However, recent studies define misinformation per deception rather than informational accuracy because misinformation can include falsehoods, selective truths, and half-truths.

Big Pharma conspiracy theories are conspiracy theories which claim that pharmaceutical companies, especially large corporations, act in sinister and secretive ways, such as concealing effective treatments, or even intentionally causing and worsening a wide range of diseases, in pursuit of profitability, or for other nefarious reasons. Some theories have included the claim that natural alternative remedies to health problems are being suppressed, the claim that drugs for the treatment of HIV/AIDS are ineffective and harmful, the claim that a cure for all cancers has been discovered but hidden from the public, claims that COVID-19 vaccines are ineffective, and that alternative cures are available for COVID-19. In most cases the conspiracy theorists have blamed pharmaceutical companies' search for profits. A range of authors have shown these claims to be false, though some of these authors nevertheless maintain that other criticisms of the pharmaceutical industry are legitimate.

<span class="mw-page-title-main">GMO conspiracy theories</span> Conspiracy theories related to GMOs

GMO conspiracy theories are conspiracy theories related to the production and sale of genetically modified crops and genetically modified food. These conspiracy theories include claims that agribusinesses, especially Monsanto, have suppressed data showing that GMOs cause harm, deliberately cause food shortages to promote the use of GM food, or have co-opted government agencies such as the United States Food and Drug Administration or scientific societies such as the American Association for the Advancement of Science.

Belief perseverance is maintaining a belief despite new information that firmly contradicts it. Such beliefs may even be strengthened when others attempt to present evidence debunking them, a phenomenon known as the backfire effect. For example, in a 2014 article in The Atlantic, journalist Cari Romm describes a study involving vaccination hesitancy. In the study, the subjects expressed their concerns of the side effects of flu shots. After being told that the vaccination was completely safe, they became even less eager to accept them. This new knowledge pushed them to distrust the vaccine even more, reinforcing the idea that they already had before.

The gateway belief model (GBM) suggests that public perception of the degree of expert or scientific consensus on an issue functions as a so-called "gateway" cognition. Perception of scientific agreement is suggested to be a key step towards acceptance of related beliefs. Increasing the perception that there is normative agreement within the scientific community can increase individual support for an issue. A perception of disagreement may decrease support for an issue.

<span class="mw-page-title-main">Psychology of climate change denial</span> Human behaviour with regards to climate change denial

The psychology of climate change denial is the study of why people deny climate change, despite the scientific consensus on climate change. The number of people denying climate change was increasing, contrary to the increasing volume of scientific evidence and the consensus of scientists that anthropogenic climate change is occurring. Several psychological barriers have been proposed to account for this phenomenon: Distance in time, space, and influence, framing, dissonance, political worldview, cultural theory, limited cognition, age differences, ideologies, comparison with others, sunk costs, views of others and perceived risk, limited behavior, conspiratorial beliefs.

Disinformation attacks are strategic deception campaigns involving media manipulation and internet manipulation, to disseminate misleading information, aiming to confuse, paralize, and polarize an audience. Disinformation can be considered an attack when it occurs as an adversarial narrative campaign that weaponizes multiple rhetorical strategies and forms of knowing—including not only falsehoods but also truths, half-truths, and value-laden judgements—to exploit and amplify identity-driven controversies. Disinformation attacks use media manipulation to target broadcast media like state-sponsored TV channels and radios. Due to the increasingly use internet manipulation on social media, they can be considered a cyber threat Digital tools such as bots, algorithms, and AI technology, along with human agents including influencers, spread and amplify disinformation to micro-target populations on online platforms like Instagram, Twitter, Google, Facebook, and YouTube.

Misinformation related to immunization and the use of vaccines circulates in mass media and social media in spite of the fact that there is no serious hesitancy or debate within mainstream medical and scientific circles about the benefits of vaccination. Unsubstantiated safety concerns related to vaccines are often presented on the internet as being scientific information. A high proportion of internet sources on the topic are "inaccurate on the whole" which can lead people searching for information to form "significant misconceptions about vaccines".

<i>Foolproof: Why We Fall for Misinformation and How to Build Immunity</i> 2023 book by psychologist Sander van der Linden

Foolproof: Why We Fall for Misinformation and How to Build Immunity is a 2023 book written by social psychologist Sander van der Linden. In the book, van der Linden makes the case for an epidemiological approach to studying and countering the spread of misinformation, comparing it to how a virus spreads in the population. Although a much broader treatise about the psychology of misinformation, Van der Linden ultimately focuses on developing his theory of psychological inoculation against misinformation, which he also refers to as 'prebunking'.
