The effect of scientific conspiracy theories on scepticism towards biotechnologies

excited to see this #conspiracytheories paper out w/ collaborators @scicomguy.bsky.social, Art Stukas, & Jim McLennan

Will write a 🧵 soon but for now here's the #openaccess link

journals.sagepub.com/doi/10.1177/...
Abstract Many conspiracy theories implicate scientists and science. We investigated the impact of exposure to scientific conspiracies about biotechnologies. Across three preregistered online studies (Ns = 1,000), participants who read information about conspiracies involving agribiotechnology companies or biobank scientists were more likely to endorse conspiracies. Other effects of exposure to conspiracy information were mixed. In Study 1, reading about an agricultural biotechnology conspiracy had a small significant effect on reducing intentions to eat genetically modified food. In Study 2, exposure to a conspiracy involving biobank scientists decreased support for biobanks, mediated by decreased trust in biobank scientists. In Study 3, this conspiracy had no effect on wider beliefs of the role of science in society (science populism), nor support of genetically modified food-promoting policies. Overall, we found that exposure to conspiracies involving scientific claims increased conspiracy belief endorsement and can further negative effects. However, the effects of conspiracies on science populism appear limited.

Good to see that Gauhar (2016) is now retracted, with a pretty frank editorial note.

The rumors about daycare centers are extremely "fit" for virality: having both novelty & familiarity (drawing on anti-immigrant tropes of criminality & exploitation); making emotional/identity appeals; are *participatory* in that ppl can create their own “evidence” by investigating local centers.

Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up.

I saw the window tracery and immediately made my friends pause the film so I could tell them.

Testing the socio-functional model: Does precarity
cause conspiracy belief?
TLDR; probably not
huge thx: Antipodean Misinformation and Conspiracies Club @matthewmatix.bsky.social @lingtax.bsky.social @scicomguy.bsky.social @srhastraea.bsky.social @eddieclarke.bsky.social & students osf.io/nq3y7/
Abstract Research seeking to explain why people believe conspira- cies has largely focused on intrapsychic factors, but there is growing research examining structural-level elements of dis- advantage. The socio-functional model of conspiracy belief (Adam-Troian et al., 2023, British Journal of Social Psycholog y, 62, 136) posits that subjective feelings of permanent inse- curity arising from objective material strain (i.e., precarity) cause conspiracy belief directly or indirectly through insti- tutional distrust. Across three preregistered studies using observational longitudinal designs over 3 (n = 637) and 11 months (n = 832), and a between-group experimental de- sign (n = 285), we use various methods to estimate causal ef- fects for this proposition during the current cost-of-living crisis. In Studies 1 and 2 using random intercept cross- lagged panel models, we find no evidence that increases in precarity temporally precede increases in conspiracy belief (or vice versa) but find stable between-persons effects over time. In Study 3, despite successfully manipulating precarity using a self-imagine paradigm, we find no direct or indirect effect on conspiracy belief through decreased government trust. We discuss the importance of using methods that per- mit credible causal inferences and key directions for future studies investigating the socio-functional model.

Belief in science-related conspiracy theories is not just a matter of knowledge: The democratic quality of countries as a protective factor
@irelopeznavarro.bsky.social & Santos-Requej

journals.plos.org/plosone/arti...
Abstract Concerns regarding the increasing prevalence of conspiracy theory beliefs are growing in public discourse. This study investigates science-related conspiracy theories due to their significant potential impact on individual and global health. Using data from a Special Eurobarometer survey (n = 37,079), our research demonstrates the importance of considering public perceptions of science when trying to understand the acceptance of such conspiracy theory beliefs. They are strongly associated with mistrust in scientists and lower level of knowledge. But there is a key factor at the country level, the quality of democracy, which plays a protective role against the acceptance of unwarranted beliefs. Even individuals with lower levels of knowledge or greater mistrust of scientists are less likely to believe in science-related conspiracy theories if they live in democratic countries than in authoritarian states.

There are always people trying to argue that misinformation doesn’t matter.

But every time I read the news there is some horrific story or policy grounded in false beliefs that have been circulating online.

Racist and xenophobic politicians trying to score points over a terrorist attack are not serving Australians. They are incompetent and have no real policy solutions to any of the problems regular Australians are facing. Therefore, they have defaulted to appealing to our worst instincts to get votes.
