Measuring belief in conspiracy theories: Validation of a French and English single-item scale

We designed, in French and in English, a single-item scale to measure people’s general tendency to believe in conspiracy theories. The validity and reliability of this scale was assessed in 3 studies (total N = 555). In Study 1 (N = 152), positive correlations between the single-item scale and 3 other conspiracy belief scales on a French student sample suggested good concurrent validity. In Study 2 (N = 292), we replicated these results on a larger and more heterogeneous Internet American sample. Moreover, the scale showed good predictive validity—responses predicted participants’ willingness to receive a bi-monthly newsletter about alleged conspiracy theories. Finally, in Study 3 (N = 111), we observed good test-retest reliability and demonstrated both convergent and discriminant validity of the single-item scale. Overall these results suggest that the single-item conspiracy belief scale has good validity and reliability and may be used to measure conspiracy belief in favor of lengthier existing scales. In addition, the validation of the single-item scale led us to develop and start validating French versions of the Generic Conspiracist Beliefs scale, the Conspiracy Mentality Questionnaire, and a 10-item version (instead of the 15-item original version) of the Belief in Conspiracy Theories Inventory

Climate change: Why the conspiracy theories are dangerous

Uncertainty surrounds the public understanding of climate change and provides fertile ground for conspiracy theories. Typically, such conspiracy theories assert that climate scientists and politicians are distorting or hijacking the science to suit their own purposes. Climate change conspiracy theories resemble other conspiracy theories in some respects, but in others they appear to be quite different. For example, climate change conspiracy theories appear to be motivated by the desire to deny or minimize an unwelcome and threatening conclusion. They also appear to be more contentious than other types of conspiracy theories. Perhaps to an unparalleled extent, people on both sides of the issue champion climate change conspiracy theories. Finally, more than other conspiracy theories, those concerning climate change appear to be more politically loaded, dividing opinion across the left-right continuum. Some empirical evidence suggests that climate change conspiracy theories may be harmful, steering people away from environmentally friendly initiatives. They therefore present a significant challenge for governments and environmental organizations that are attempting to convince people to take action against global warming

Conspiracy theories fuel prejudice towards minority group

Some 60 of British people believe in at least one conspiracy theory, a recent poll reveals. From the idea that 9/11 was an inside job to the notion that climate change is a hoax, conspiracy theories divert attention away from the facts in favour of plots and schemes involving powerful and secret groups. With the aid of modern technology, conspiracy theories have found a natural home online

Perceptions of Local Leaders in Shale Energy Communities: Views on Influence, Inclusion, and Trust (A Research Note)

Data collected from random samples of residents and absentee landowners in two counties in the Eagle Ford Shale region of South Texas were used to examine the perceptions regarding influence, inclusion, and trust of local leaders and other stakeholders in the area. Additionally, two hypotheses pertaining to the association between individuals’ perceptions of inclusion by local governments—both city and county—and individuals’ levels of trust in those governments as sources of information about the positive and negative impacts of shale oil and/or natural gas development were tested and supported. Substantive descriptive and statistical analyses are reported

Written evidence submitted to Home Affairs Committee on Home Office preparedness for Covid-19 (Coronavirus) Inquiry (COR0158).

Executive summarya. A growing body of research has shown that conspiracy theories can negatively impact individuals and society in a variety of areas, including their work life, medical choices and political engagement.b. In our evidence, we articulate how conspiracy theories are likely to have a negative impact during the COVID-19 crisis in similar ways.c. Counterarguments to dispel conspiracy theories are important, but developing proactive approaches (such as improving people’s critical thinking abilities) is also crucial

A decomposition-based approach to uncertainty analysis of feed-forward multicomponent systems

To support effective decision making, engineers should comprehend and manage various uncertainties throughout the design process. Unfortunately, in today's modern systems, uncertainty analysis can become cumbersome and computationally intractable for one individual or group to manage. This is particularly true for systems comprised of a large number of components. In many cases, these components may be developed by different groups and even run on different computational platforms. This paper proposes an approach for decomposing the uncertainty analysis task among the various components comprising a feed-forward system and synthesizing the local uncertainty analyses into a system uncertainty analysis. Our proposed decomposition-based multicomponent uncertainty analysis approach is shown to be provably convergent in distribution under certain conditions. The proposed method is illustrated on quantification of uncertainty for a multidisciplinary gas turbine system and is compared to a traditional system-level Monte Carlo uncertainty analysis approach.SUTD-MIT International Design CentreUnited States.

When is it wrong to eat animals? The relevance of different animal traits and behaviours

Research suggests that animals’ capacity for agency, experience, and benevolence predict beliefs about their moral treatment. Four studies built on this work by examining how fine‐grained information about animals’ traits and behaviours (e.g., can store food for later vs. can use tools) shifted moral beliefs about eating and harming animals. The information that most strongly affected moral beliefs was related to secondary emotions (e.g., can feel nostalgia), morality (e.g., will share food with others), empathy (e.g., can feel others pain), social connections (e.g., will look for deceased family members), and moral patiency (e.g., can feel pain). In addition, information affected moral judgements in line with how it affected superordinate representations about animals’ capacity for experience/feeling but not agency/thinking. The results provide a fine‐grained outline of how, and why, information about animals’ traits and behaviours informs moral judgements

Why conspiracy theories matter: A social psychological analysis

Although conspiracy theories have arguably always been an important feature of social life, they have only attracted the attention of social psychologists in recent years. The last decade, however, has seen an increase in social psychological research on this topic that has yielded many insights into the causes and consequences of conspiracy thinking. In this article, we draw on examples from our own programme of research to highlight how the methods and concepts of social psychology can be brought to bear on the study of conspiracy theories. Specifically, we highlight how basic social cognitive processes such as pattern perception, projection, and agency detection predict the extent to which people believe in conspiracy theories. We then highlight the role of motivations such as the need for uniqueness, and the motivation to justify the system, in predicting the extent to which people adopt conspiracy explanations. We next discuss how conspiracy theories have important consequences for social life, such as decreasing engagement with politics and influencing people’s health and environmental decisions. Finally, we reflect on some of the limitations of research in this domain and consider some important avenues for future research
