Following the COVID-19 playbook and battling another infodemic: conspiracy beliefs around human monkeypox among the Lebanese population.

INTRODUCTION: The non-endemic multicountry outbreak of monkeypox (MPX) has emphasized the issue of conspiracy theories that go viral in times of societal crisis. Now, it is the turn of MPX to join COVID-19 in the conspiracy theory realm. Social media outlets were flooded by a scourge of misinformation as soon as MPX cases began to appear with an evident cross-pollination between diverse conspiracy theories. Given the adverse consequences of conspiracy beliefs, this study aimed to assess the extent of endorsement of MPX conspiracy beliefs among the Lebanese population and to identify its associated factors. METHODS: Using a convenience sampling technique, a web-based cross section was conducted among Lebanese adults. Data were collected using an Arabic self-reported questionnaire. Multivariable logistic regression was performed to identify the factors associated with the MPX conspiracy beliefs scale. RESULTS: Conspiracy beliefs regarding emerging viruses including MPX were detected among 59.1% of Lebanese adults. Participants endorsed particularly the conspiracy theories linking the virus to a deliberate attempt to reduce the size of the global population (59.6%), gain political control (56.6%) or pharmaceutical companies' financial gain (39.3%), in addition to the manmade origin of MPX (47.5%). Remarkably, the majority of surveyed adults exhibited a negative attitude toward the government's preparedness for a potential MPX outbreak. However, a positive attitude was revealed toward the effectiveness of precautionary measures (69.6%). Female participants and those having a good health status were less likely to exhibit a higher level of conspiracy beliefs. On the contrary, divorced or widowed adults, those having a low economic situation, poor knowledge level, and negative attitude either toward the government or precautionary measures were more prone to disclose a higher level of conspiracy beliefs. Notably, participants relying on social media to get information about MPX were also more likely to have a higher level of conspiracy beliefs compared to their counterparts. CONCLUSIONS: The widespread extent of conspiracy beliefs endorsement regarding MPX among the Lebanese population urged the policymakers to find ways to reduce people's reliance on these theories. Future studies exploring the harmful impacts of conspiracy beliefs on health behaviors are recommended.

COVID-19 conspiracy beliefs and vaccinations: A conceptual replication study in Turkey

Pivetti et al. (2021a;2021b) examined links between COVID-related conspiracy beliefs and acceptance of vaccinations in Italy and Finland in 2020. They found that moral purity negatively predicted confidence in science, whereas political orientation predicted COVID-related conspiracy beliefs. Confidence in science, general conspiracy beliefs, and COVID-related conspiracy beliefs were found to negatively predict support for governmental restrictions and attitudes towards vaccines, and positively predict perceptions of informational contamination. Finally, attitudes towards vaccines in general strongly predicted attitudes towards the COVID-19 vaccine. The current research seeks to replicate these findings conceptually on a predominately Muslim sample (N = 570, M age = 26.69, 69.8% females) in Turkey in 2021, when the COVID vaccines were widely available. Measures of religiosity and left, center, and right political orientations were added to the original instrument. Hypothesized serial mediational models were tested using structural equation modelling. Results revealed that left and center political orientations positively predicted COVID-related conspiracy beliefs and confidence in science. Religiosity was negatively related to confidence in science. Confidence in science and COVID-related conspiracy beliefs predicted general attitudes toward vaccines. Conspiracy beliefs predicted COVID-related conspiracy beliefs, which in turn negatively predicted support for government restrictions and positively predicted distrust in mainstream media. Attitudes towards vaccines were strongly and positively related to attitudes toward COVID-19 vaccines.

Influence of conspiracy mindset, trust in science, and political affiliation on COVID-19 reactance

The COVID-19 pandemic exposed extreme divisions in the social and political structure of the United States. When health organizations recommended strategies such as physical distancing, hand hygiene, sanitation of surfaces, and isolating when sick to slow the spread of the disease, Americans appeared to divide into two factions;those who followed the public health guidance and those who persistently ignored it, often voicing perceptions of loss of freedom due to the guidance. The purpose of this quantitative study was to examine the extent to which political affiliation moderated the relationship between conspiracy mindset, trust in science, and reactance responses to COVID-19 public health protocols. The social identity approach, a blend of social identity and self-categorization theories explains the polarization in the United States to public health guidance designed to slow the spread of disease. Online surveys were administered via Survey Monkey to 220 American citizens who were active politically. Results indicated that political conservatives were significantly more likely to endorse conspiracy theories and to resist compliance with COVID-19 public health protocols. Additionally, those who distrusted science were significantly more likely to resist compliance with COVID-19 mitigation practices. Findings from this study have the potential to promote positive social change through a better understanding of the reasons for resistance to public health protocols designed to thwart the spread of COVID-19. Importantly, these results can be used to develop messaging that targets those susceptible to conspiracy beliefs and instead direct their attention to the science that informs public safety protocols in the interest of us all. .

COVID-19 vaccine hesitancy is associated with beliefs on the origin of the novel coronavirus in the UK and Turkey.

BACKGROUND: Much research effort is focused on developing an effective vaccine for combatting coronavirus disease 2019 (COVID-19). Vaccine development itself, however, will not be enough given that a sufficient amount of people will need to be vaccinated for widespread immunity. Vaccine hesitancy is on the rise, varies across countries, and is associated with conspiratorial worldview. Given the rise in COVID-19-related conspiracy theories, we aimed to examine the levels of COVID-19 vaccine hesitancy and its association with beliefs on the origin of the novel coronavirus in a cross-cultural study. METHODS: We conducted an online survey in the UK (N = 1088) and Turkey (N = 3936), and gathered information on participants' willingness to vaccinate for a potential COVID-19 vaccine, beliefs on the origin of the novel coronavirus, and several behavioural and demographic predictors (such as anxiety, risk perception, government satisfaction levels) that influence vaccination and origin beliefs. RESULTS: In all, 31% of the participants in Turkey and 14% in the UK were unsure about getting themselves vaccinated for a COVID-19 vaccine. In both countries, 3% of the participants rejected to be vaccinated. Also, 54% of the participants in Turkey and 63% in the UK believed in the natural origin of the novel coronavirus. Believing in the natural origin significantly increased the odds of COVID-19 vaccine acceptance. CONCLUSIONS: Our results point at a concerning level of COVID-19 vaccine hesitancy, especially in Turkey, and suggest that wider communication of the scientific consensus on the origin of the novel coronavirus with the public may help future campaigns targeting COVID-19 vaccine hesitancy.

Positive and negative experiences with the COVID-19 pandemic among lonely and non-lonely populations in Germany.

The COVID-19 pandemic is causing an epidemic of loneliness. Previous studies have shown the differences in positive and negative experiences of lonely and non-lonely people in a non-pandemic setting. However, it is unclear how the drastic alteration of the COVID-19 pandemic may influence peoples' reactions and beliefs, especially among those who feel lonely. Our study aims to examine the positive and negative experiences among lonely and non-lonely people. We undertook a cross-sectional online survey of the general population in Germany (N = 1,758) from May 2020 to May 2022. We assessed their feelings of loneliness with the short eight-item UCLA Loneliness Scale (ULS-8), their positive and negative experience of living in the COVID-19 pandemic as well as their psychological distress regarding the pandemic with the COVID-19 Peritraumatic Distress Index (CPDI). We found lonely individuals (ULS-8 score ≥ 16) reported fewer positive experiences of living in the COVID-19 pandemic, for example, less time with loved ones [z (1, 756) = -2.5, p = 0.012] and less sense of togetherness [z (1, 756) = -2.39, p = 0.017] as compared to non-lonely individuals. Meanwhile, they experienced more negative experiences, for example, worry and fear [z (1, 756) = 6.31, p < 0.001] compared with non-lonely individuals. Interestingly, lonely people were less likely to view the pandemic as a conspiracy than non-lonely people were [z (1, 756) = -3.35, p < 0.001]. Our results may give insight into attribution bias and the negative affect of lonely people during the COVID-19 pandemic as well as highlight the experience of non-lonely people and raise the question of differences in conspiracy beliefs. For pandemic preparedness and response, decision-makers may focus on interventions to foster social cohesion, empower people, build resilience, and most importantly provide timely social care.

Underlying motivators for anti-vaccination attitudes amongst regional Sunshine Coast parents in Australia.

BACKGROUND: The Immunisation Register of Australia reports that childhood vaccination rates in some regional areas are below herd immunity levels. This is a concern for the health and well-being of society, as regions with low vaccination rates have an increased risk of disease outbreaks. OBJECTIVE: This study explored psychological motivators as predictors of anti-vaccination attitudes amongst parents living on the Sunshine Coast (Queensland), Australia. METHODS: A cross-sectional survey design explored anti-vaccination attitudes, conspiratorial thinking, psychological reactance, trust in government and magical beliefs about health in 1050 parents (968 mothers). RESULTS: The predictor variables significantly accounted for 42% of the variance in parental anti-vaccination attitudes. The strongest predictor of anti-vaccination attitudes was lower levels of trust in government. CONCLUSION: The findings contribute to understanding of psychological factors motivating anti-vaccine attitudes in Australian parents. The findings may help inform health communication campaign effectiveness in their alignment with individual underlying motivations.

Conspiracy Theories about Infectious Diseases: An Introduction

Understanding why people believe conspiracy theories related to disease outbreaks and the consequences of such beliefs is critical for combating both the COVID-19 pandemic and its corresponding "infodemic.” In the introduction to this special issue on conspiracy theories about infectious diseases, the authors first provide a brief overview of the narratives of conspiracy theories related to COVID-19, followed by a review of extant theoretical frameworks regarding the psychology of conspiracy beliefs. Specifically, they discuss how epistemic, existential, and social needs contribute to the holding of conspiracy beliefs. Then, the authors summarize the major findings from the nine empirical articles featured in this issue, particularly how they shed light on the antecedents and consequences of disease-related conspiracy beliefs. They conclude by discussing future directions for the study of disease-related conspiracy beliefs.

Conspiracy beliefs and attitudes toward COVID-19 vaccinations

During the coronavirus pandemic, this study aimed to investigate the impact of conspiracy beliefs on Finnish attitudes toward vaccinations in general and COVID-19 vaccinations in particular. This study was a conceptual replication in Finland of a study by Pivetti et al. (2021). Some 529 Finnish participants responded to a self-report questionnaire during the partial lockdown in Finland in spring 2020. The hypothesized relationships between variables of interest were integrated in a serial multiple mediation model via structural equation modelling. Results showed that endorsing general conspiracy beliefs directly predicted (1) general attitudes toward vaccines and (2) COVID-19 conspiracy beliefs, and indirectly predicted (3) attitudes toward COVID-19 vaccines via the serial mediation of COVID-19 conspiracy beliefs and general attitudes toward vaccines. As for the antecedents of beliefs in conspiracy theories, political orientation and moral purity predicted beliefs in COVID-19 conspiracy theories. Trust in science was inversely related to general conspiracy beliefs. As for the consequences of conspiracy beliefs, COVID-19 conspiracy beliefs directly predicted support for governmental restrictions (negatively) and the perception of informational contamination (positively).

The association of conspiracy beliefs and the uptake of COVID-19 vaccination: a cross-sectional study.

The COVID-19 pandemic revealed that health denialism might be an important determinant of adherence to preventive measures during epidemic challenges. Conspiracy beliefs seem to be one of the most visible manifestations of denialism in society. Despite intensive efforts to promote COVID-19 vaccinations, the number of citizens reluctant to get vaccinated was very large in many countries. The main aim of this study was the analysis of the association between the acceptance of the COVID-19 vaccination and conspiracy beliefs among adult Internet users in Poland. The analysis was based on data from a survey performed on a sample of 2008 respondents in October 2021. Uni- and multivariable logistic regression models were applied to evaluate the association between attitudes towards COVID-19 vaccination and generic conspiracist, vaccine-conspiracy, and COVID-19-related conspiracy beliefs. In the multivariable model, the effect of conspiracy beliefs was adjusted for the level of vaccine hesitancy, future anxiety, political sympathies, and socio-demographic variables. Univariate regression models showed that COVID-19 vaccination acceptance is significantly lower among respondents with higher levels of all three types of conspiracy beliefs. In the multivariable model, the effect of COVID-19-related and vaccine conspiracy beliefs, but not generic conspiracist beliefs, was maintained after adjusting for vaccine hesitancy. We conclude that conspiracy beliefs should be treated as a potential indicator of lower adherence to preventive measures during epidemic challenges. The respondents revealing a high level of conspirational thinking are a potential group for intensified actions which employ health educational and motivational interventions.

Vaccine Conspiracy Beliefs Scale: Validation and Measurement Invariance in a Youth Sample.

The Vaccine Conspiracy Beliefs Scale (VCBS) is a widely used measure of conspiracy beliefs about vaccines, but evidence of its validity and measurement invariance, especially in youth samples, is still largely missing. The present study examined VCBS scores' factor structure, measurement invariance, convergent and discriminant validity, and incremental predictive validity. A sample of 803 Serbian youths (age range 15-24; 59.2% females) was recruited for the study. A modified single-factor model of the VCBS was supported, and showed evidence of full scalar invariance across gender, age, vaccination status, and personal history of COVID-19. Evidence of the VCBS scores' convergent and discriminant validity was obtained by examining associations with general conspiracy beliefs, vaccination attitudes, vaccination knowledge, intentions to get vaccinated against COVID-19, paranoia worries, fear of injections and blood draws, importance of God, self-rated health, and self-rated family's financial situation. The VCBS scores predicted a unique variance in the intention to get vaccinated against COVID-19, over and above vaccination attitudes and vaccination knowledge. The results suggest that the VCBS is a valid measure of vaccine conspiracy beliefs in youth.

Does Belief in Conspiracy Theories Affect Interpersonal Relationships?

In recent years, researchers have begun to study the social consequences of conspiracy beliefs. However, little research has investigated the impact of conspiracy beliefs on interpersonal relationships. In this review, we draw attention to this issue by summarizing available empirical evidence and proposing potential social-psychological mechanisms to explain whether and why conspiracy theories affect interpersonal relationships. We firstly discuss that the attitude change that often accompanies the internalization of conspiracy beliefs might distance people's opinions and, consequently, erode their relationships. Furthermore, we argue that the stigmatizing value of conspiracy theories can negatively affect the evaluation of conspiracy believers and discourage others from getting close to them. Finally, we consider that the misperception of social norms associated with the acceptance of certain conspiracy narratives can lead conspiracy believers to engage in non-normative behavior. Others are likely to perceive such behavior negatively, resulting in diminished interpersonal interaction. We highlight the need for further research to address these issues, as well as the potential factors that may prevent relationships being eroded by conspiracy beliefs.

Populist attitudes, anti-technocratic attitudes, and Covid-related conspiracy beliefs across Europe

This paper focuses on the puzzle of how what could have been initially regarded as a decline in populist support became compatible with widespread conspiracy beliefs during the Covid crisis. Analyzing survey data collected in 16 countries in June–July 2021, we explore how support for Covid conspiracies is embedded in the attitudinal map of individuals and offer three contributions to the literature on conspiracy beliefs and populism. First, we employ an original scale for measuring conspiracy beliefs benchmarked both on a general conspiratorial mindset item and on a non-conspiratorial item. Second, building on the multidimensionality of the concept of populism and its empirical distinction to neighboring anti-technocratic attitudes, we employ a new scale developed and tested by Bertsou and Caramani (2022) that allows us to highlight the differential role that these attitudes play into conspiracy beliefs. Third, we inquire into the role played by previous factors associated with populist attitudes, such as trust and ideology, but also understudied ones such as performance evaluations and (dis)satisfaction with the management of the crisis at the domestic and at the EU level. Our results show that conspiracy, populist, and anti-technocratic attitudes are highly prevalent and related to each other, despite an initial "rally” effect in the beginning of the pandemic. Furthermore, government and EU performance in the crisis matter, net of trust and ideology, playing a moderating role in the populism–conspiracy nexus. © 2023, The Author(s).

Hippies Next to Right-Wing Extremists?: Identifying Subgroups of Antilockdown Protesters in Germany Using Latent Profile Analysis

To reduce the spread of COVID-19, adherence to protective measures was crucial around the world. While most complied with these measures, a vocal minority protested against them. Early reports emphasized the unusual heterogeneity of these protests: Hippies and esoterics marched alongside conspiracy theorists and neo-Nazis. We examined what these protestors might (and might not) have in common. A large study with antilockdown protestors in Germany (N = 1,700) revealed four subgroups: centrists, politically undifferentiated, left-wingers, and right-wingers. Beyond that, these subgroups demonstrated striking similarities: All endorsed conspiracy beliefs, misinformation, esotericism, and vaccine hesitancy to a similar extent. These beliefs share that they are scientifically unfounded and epistemically unwarranted. They may unite individuals from diverse political backgrounds in the antilockdown protests. © 2023 The Author(s).

Catastrophizing life's problems: On the relationship between attachment anxiety and belief in conspiracy theories

Research has shown that attachment anxiety predicts higher agreement with conspiracy theories. In this research, we aimed to examine this relationship further. Specifically, we investigated the importance of catastrophizing-viewing situations as considerably worse than they are-in explaining the relationship between attachment anxiety and belief in conspiracy theories. Chapter 1 provides an overview of the literature on the psychology of conspiracy theories and adult attachment theory. Then, across six studies (Chapter 2), we found that catastrophizing (regarding pain, stress, and social situations) explained the relationship between attachment anxiety and conspiracy beliefs. In two further studies (Chapter 3), we found that attachment anxiety and conspiracy beliefs were associated with communal orientation (the desire that one's needs should be met by others versus the desire to meet the needs of others), which was moderated by catastrophizing, across two studies. Finally, in two studies (Chapter 4), we found attachment anxiety to be partially associated with COVID-19 powerlessness and COVID-19 conspiracy beliefs, whereas attachment avoidance was shown to be consistently associated with them. Implications and recommendations for future research are discussed (Chapter 5), including the need for more experimental or longitudinal designs, and interventions that reduce catastrophic thinking with the aim of reducing the appeal of conspiracy theories.

COVID-19 conspiracy theories

Conspiracy theories started to appear on social media immediately after the first news about COVID-19. Is the virus a hoax? Is it a bioweapon designed in a Chinese laboratory? These conspiracy theories typically have an intergroup flavour, blaming one group for having some involvement in either manufacturing the virus or controlling public opinion about it. In this article, I will discuss why people are attracted to conspiracy theories in general, and why conspiracy theories seem to have flourished during the pandemic. I will discuss what the consequences of these conspiracy theories are for individuals, groups, and societies. I will then discuss some potential strategies for addressing the negative consequences of conspiracy theories. Finally, I will consider some open questions for research regarding COVID-19 conspiracy theories, in particular focusing on the potential impact of these conspiracy theories for group processes and intergroup relations.

Examining a domain-specific link between perceived control and conspiracy beliefs: a brief report in the context of COVID-19.

Although anecdotal evidence suggests that control-threatening situations are associated with an increase in conspiracy beliefs, existing research does not support this "compensatory control" hypothesis. In the current study, we test a more refined hypothesis: that the link between control threat and conspiracy beliefs is domain specific, such that perceived control in a particular domain should lead to conspiracy beliefs pertaining to that domain only. Moreover, given that conspiracy beliefs are stigmatized (i.e., not socially acceptable), we propose that they should be endorsed only when other compensatory systems are frustrated. We test these ideas in the context of the COVID-19 pandemic. Participants from North Macedonia and New Zealand, who differed in perceived government effectiveness, filled in a questionnaire measuring domain-specific and domain-general perceived control, as well as domain-specific and domain-general conspiracy beliefs. As expected, domain specificity of the control threat predicted domain-specific conspiracy beliefs in the Macedonian group only. The results have implication for compensatory control theory, suggesting that the compensatory process may not always be as fluid as believed.

Dehumanization During the COVID-19 Pandemic.

Communities often unite during a crisis, though some cope by ascribing blame or stigmas to those who might be linked to distressing life events. In a preregistered two-wave survey, we evaluated the dehumanization of Asians and Asian Americans during the COVID-19 pandemic. Our first wave (March 26-April 2, 2020; N = 917) revealed dehumanization was prevalent, between 6.1% and 39% of our sample depending on measurement. Compared to non-dehumanizers, people who dehumanized also perceived the virus as less risky to human health and caused less severe consequences for infected people. They were more likely to be ideologically Conservative and believe in conspiracy theories about the virus. We largely replicated the results 1 month later in our second wave (May 6-May 13, 2020; N = 723). Together, many Americans dehumanize Asians and Asian Americans during the COVID-19 pandemic with related perceptions that the virus is less problematic. Implications and applications for dehumanization theory are discussed.

Coronavirus conspiracy beliefs in the German-speaking general population: endorsement rates and links to reasoning biases and paranoia.

BACKGROUND: Coronavirus-related conspiracy theories (CT) have been found to be associated with fewer pandemic containment-focused behaviors. It is therefore important to evaluate associated cognitive factors. We aimed to obtain first endorsement rate estimates of coronavirus-related conspiracy beliefs in a German-speaking general population sample and investigate whether delusion-related reasoning biases and paranoid ideation are associated with such beliefs. METHODS: We conducted a cross-sectional non-probability online study, quota-sampled for age and gender, with 1684 adults from Germany and German-speaking Switzerland. We assessed general and specific coronavirus conspiracy beliefs, reasoning biases [jumping-to-conclusions bias (JTC), liberal acceptance bias (LA), bias against disconfirmatory evidence (BADE), possibility of being mistaken (PM)], and paranoid ideation, using established experimental paradigms and self-report questionnaires. RESULTS: Around 10% of our sample endorsed coronavirus-related CT beliefs at least strongly, and another 20% to some degree. Overall endorsement was similar to levels observed in a UK-based study (Freeman et al., 2020b). Higher levels of conspiracy belief endorsement were associated with greater JTC, greater LA, greater BADE, higher PM, and greater paranoid ideation. Associations were mostly small to moderate and best described by non-linear relationships. CONCLUSIONS: A noticeable proportion of our sample recruited in Germany and German-speaking Switzerland endorsed coronavirus conspiracy beliefs strongly or to some degree. These beliefs are associated with reasoning biases studied in delusion research. The non-probability sampling approach limits the generalizability of findings. Future longitudinal and experimental studies investigating conspiracy beliefs along the lines of reasoning are encouraged to validate reasoning aberrations as risk factors.

COVID-19 as an undesirable political issue: Conspiracy beliefs and intolerance of uncertainty predict adhesion to prevention measures.

Conspiracy theories thrive in moments of crises because they provide straightforward answers that assist individuals in coping with threats. The COVID-19 outbreak is such a crisis and is boosted by the political turmoil related to the politicization of the pandemic in some countries. To assess the role of political partisanship, intolerance of uncertainty (IU), and conspiracy beliefs in our two criterion variables (support for COVID-19 prevention measures and compliance with social distancing), we applied an online questionnaire to 662 participants. Our results indicate direct effects of political partisanship on support for COVID-19 prevention measures and non-compliance with social distancing while IU has not directly affected any of them. We have also found a significant effect of political partisanship on conspiracy theory dimensions involving personal wellbeing (PW) and control of information (CI) but not government malfeasance (GM) ones. Moreover, beliefs in CI theories predicted non-compliance with social distancing. Intolerance of uncertainty, on its turn, predicted the three dimensions of conspiracy beliefs. As to interaction effects, belief in GM, PW, and CI conspiracy theories moderated the effect of political partisanship on support for COVID-19 prevention measures whereas only belief in GM and PW theories moderated the effect of IU on past non-compliance with social distancing. Overall, our results suggest the relevance of diminishing politicization around the virus, providing basic scientific knowledge to the general population, and assisting individuals in coping with uncertainty. Besides, these findings provide insights into developing information campaigns to instruct the population to cope with the pandemic, producing behavioral change at societal and individual levels.
