Conspiracy beliefs prospectively predict health behavior and well-being during a pandemic

The motivations and reputational consequences of spreading conspiracy theories

Some people deliberately spread conspiracy theories. What are the reputational benefits and costs of doing so? The Adaptive-Conspiracism hypothesis proposes that it pays to be vigilant against possible conspiracies, especially in case of intergroup threat. Those who spread conspiracy theories may therefore be seen as valuable group members. Few studies have focused on the reputational impact of spreading a conspiracy theory. We conducted five studies (NPilot = 303; NStudy1 = 388; NStudy2 = 560; NStudy3 = 391; NStudy4 = 373) where participants rated a conspiracy spreader (vs. a neutral person) on a range of personality traits in different intergroup contexts. The results indicated that conspiracy spreaders were consistently perceived as more dominant and less warm than people making non-conspiratorial claims about certain events. Moreover, intergroup conflict attenuated the negative effects of spreading conspiracy theories on competence and warmth. These findings support the notion that besides drawbacks, spreading conspiracy theories can have benefits for the spreader's reputation, particularly during an intergroup conflict.

The negative impact of misinformation and vaccine conspiracy on COVID-19 vaccine uptake and attitudes among the general public in Iraq

Background

Vaccine hesitancy is a major barrier to infectious disease control. Previous studies showed high rates of COVID-19 vaccine hesitancy in the Middle East. The current study aimed to investigate the attitudes towards COVID-19 vaccination and COVID-19 vaccine uptake among adult population in Iraq.

Methods

This self-administered survey-based study was conducted in August-September 2022. The survey instrument assessed participants' demographics, attitudes to COVID-19 vaccination, beliefs in COVID-19 misinformation, vaccine conspiracy beliefs, and sources of information regarding the vaccine.

Results

The study sample comprised a total of 2544 individuals, with the majority reporting the uptake of at least one dose of COVID-19 vaccination (n = 2226, 87.5 %). Positive attitudes towards COVID-19 vaccination were expressed by the majority of participants (n = 1966, 77.3 %), while neutral and negative attitudes were expressed by 345 (13.6 %) and 233 (9.2 %) participants, respectively. Factors associated with positive attitudes towards COVID-19 vaccination in multivariate analysis included disbelief in COVID-19 misinformation and disagreement with vaccine conspiracies. Higher COVID-19 vaccine uptake was significantly associated with previous history of COVID-19 infection, higher income, residence outside the Capital, disbelief in COVID-19 misinformation, disagreement with vaccine conspiracies, and reliance on reputable information sources.

Conclusion

COVID-19 vaccine coverage was high among the participants, with a majority having positive attitudes towards COVID-19 vaccination. Disbelief in COVID-19 misinformation and disagreement with vaccine conspiracies were correlated with positive vaccine attitudes and higher vaccine uptake. These insights can inform targeted interventions to enhance vaccination campaigns.

Anti-establishment sentiments: realistic and symbolic threat appraisals predict populist attitudes and conspiracy mentality

Previous research has found that populist attitudes and conspiracy mentality - here summarised as anti-establishment attitudes - increase when people feel threatened. Two types of intergroup threat have been distinguished, namely realistic threats (pertaining to socio-economic resources, climate, or health), and symbolic threats (pertaining to cultural values). However, there is no agreement on which types of threat and corresponding appraisals would be most important in predicting anti-establishment attitudes. We hypothesise that it is the threat itself, irrespective of its cause, that predicts anti-establishment attitudes. In the current paper, we conducted new (multilevel) regression analyses on previously collected data from four high-powered studies with multiple time points (Study 1) or collected in multiple nations (Studies 2-4). All studies included a populist attitudes scale, a conspiracy mentality scale, and different types of threat and emotion measures, reflecting both realistic and symbolic threats. Across studies, both realistic and symbolic threats positively predicted anti-establishment attitudes. The results support an emotional appraisal approach to anti-establishment attitudes, which highlights the importance of anxiety and feeling threatened regardless of what type of event elicits the threat.

U.S. College Students' Sexual Risk Behaviors Before and During the Early COVID-19 Pandemic

The present study describes changes in young adults' sexual behaviors during the early COVID-19 pandemic. Latent class growth analyses (LCGAs) conducted with four waves of data collected between July 2019 to May 2020 in N = 775 college students (Mage = 18.61, SD = 0.33; 50.3% female, 90.2% White) revealed the presence of high- and low-risk classes in separate models for oral, vaginal, and anal sexual risk taking. As anticipated, vaginal and oral risk taking declined in spring 2020. Membership in high-risk trajectories was attributable to high COVID-19-related financial problems, early sexual debut, low self-control, and being in a romantic relationship. Other COVID-19 factors and demographic control variables were not linked to trajectory membership. Thus, while many young adults' sexual risk taking changed during the early pandemic, their perceptions of and experiences with COVID-19 were not predictive of sexual risk trajectory membership.

Unfounded beliefs, distress and powerlessness: A three-wave longitudinal study

The aim of the study was to examine the relationships between unfounded COVID-19 beliefs and distress and powerlessness, specifically, whether distress and powerlessness are causes or consequences of unfounded COVID-19 beliefs represented by conspiracy beliefs and pseudoscientific beliefs regarding treatment and measures. Unfounded beliefs were assessed using the COVID-19 Unfounded Beliefs Scale; distress was measured with the Symptom Checklist-10, and powerlessness was measured with four items measuring the feeling of losing control. Data collection took place during three phases of the pandemic in Slovakia (October 2021, N = 1838; July 2022, N = 1,420; April 2023, N = 925). Results suggest that individuals with stronger unfounded beliefs about COVID-19 reported greater powerlessness longitudinally, and individuals with stronger COVID-19 unfounded beliefs treatment and measures reported greater distress longitudinally (notably, beliefs about COVID-19 measures in the first wave were associated with distress in the second wave, and beliefs about COVID-19 treatment in the second wave were associated with distress in the third wave). The present findings corroborate an existential threat model of conspiracy theories that says the relationship between unfounded beliefs and indicators of well-being is bidirectional, so interventions should be focused both on eliminating the unfounded beliefs and strengthening well-being.

Investigating Beliefs in Anti-Vax Conspiracy Theories among Medical Students

While the doctors' role in immunization is essential, their lack of knowledge or vaccine hesitancy may affect their ability to communicate effectively and educate patients about vaccination, vaccine hesitancy, and vaccine conspiracy theories. This, in turn, may hinder health policy aimed at fighting infectious diseases. Vaccine hesitancy is prevalent not only among the general population but also among healthcare workers; thus, this study is aimed at assessing future doctors' attitudes towards anti-vax conspiracy theories. A total of 441 medical students at Poznan University of Medical Sciences completed a web-based survey designed to explore their attitudes toward the six most prevalent anti-vaccine conspiracy theories. The survey showed that although over 97% of future doctors support vaccinations as an effective form of fighting infectious diseases, and 80% did not believe in any anti-vax conspiracy theory, a significant fraction of 20% of medical students either believed in at least one such theory or were unsure. It has also shown that male and younger students who had not received a flu vaccination and defined themselves as politically right-wing or conservative and religious were more likely to believe in anti-vax conspiracy theories. Our data suggest that, in order to overcome medical students' ambivalent attitudes towards anti-vax conspiracy theories, they should receive more education about the importance of vaccination in preventing disease and about effective ways to combat vaccine hesitancy and anti-vax conspiracy theories.

How perceived coercion polarizes unvaccinated people: The mediating role of conspiracy beliefs

During the COVID-19 pandemic, different policies were implemented to increase vaccination uptake. Meanwhile, conspiracy theories spread widely, and vaccinated versus unvaccinated people increasingly polarized against each other. This study examined the associations between perceived vaccination coercion, conspiracy beliefs and polarization. We tested the relationship of vaccination status with perceived vaccination coercion, conspiracy beliefs, and polarization, with a total sample size of N = 1202 (n = 400 in China, n = 401 in the US, and n = 401 in the UK), among them n = 603 were vaccinated and n = 599 were unvaccinated. As pre-registered, unvaccinated people perceived more vaccination coercion and endorsed more conspiracy theories. Conspiracy mentality was positively related to perceived coercion. Contrary to our hypotheses, vaccinated people were more polarized toward unvaccinated people than vice versa. Finally, conspiracy beliefs mediated the link between perceived coercion and polarization among unvaccinated people.

Vaccine conspiracy association with higher COVID-19 vaccination side effects and negative attitude towards booster COVID-19, influenza and monkeypox vaccines: A pilot study in Saudi Universities

Conspiracies regarding vaccines are widely prevalent, with negative consequences on health-seeking behaviors. The current study aimed to investigate the possible association between the embrace of vaccine conspiracies and the attitude to booster COVID-19, seasonal influenza, and monkeypox (mpox) vaccinations as well as the perceived side effects following COVID-19 vaccination. The target population involved academic staff and university students in health colleges in the Kingdom of Saudi Arabia. A self-administered questionnaire was distributed in January 2023 to collect data on participants' demographics, self-reported side effects following each dose, willingness to get booster COVID-19, seasonal influenza, and mpox vaccinations, as well as an evaluation of vaccine conspiracies and attitude to mandatory vaccination. Among the 273 participants, the willingness to receive yearly booster COVID-19 vaccination was observed among 26.0% of the participants, while it was 46.9% and 34.1% for seasonal influenza and mpox vaccinations, respectively. Multinomial logistic regression analyses demonstrated a significant correlation between endorsing vaccine conspiracies and higher frequency of self-reported side effects following uptake of the second and third doses of COVID-19 vaccines. Vaccine conspiracies were also correlated with attitude toward booster COVID-19, influenza, mpox, and mandatory vaccination. The findings of this pilot study highlighted the potential adverse impact of the preexisting notions and negative attitudes toward vaccines, which could have contributed to heightened perceived side effects following COVID-19 vaccination. The study also highlighted the ongoing divisions concerning mandatory vaccination policies, emphasizing the need for cautious implementation of this strategy as a last resort for public health benefit.

Insomnia is associated with conspiracy mentality, psychological distress, and psychological well-being

RATIONALE

Conspiracy theories are frequently encountered as they exist across all domains of life, from interpersonal issues in the workplace to global events. Research has primarily focused on uncovering the antecedents of conspiracy beliefs; meanwhile, little research has examined the impacts of possessing a conspiracy mentality.

OBJECTIVE

In the current research, we examined the relationships of conspiracy mentality with perceived control, insomnia, psychological well-being (i.e., positive emotions, engagement, relationships, meaning, and achievement), and psychological distress (i.e., anxiety and depression).

METHODS

Participants (N = 388) reported their conspiracy mentality at Time 1 and then completed measures assessing perceived control, insomnia, psychological well-being, and psychological distress 1 month later at Time 2. We conducted regression analyses, structural equation modeling, and bootstrapping analyses to test our predictions that conspiracy mentality predicts insomnia through thwarted perceived control and that this relationship carries direct implications for psychological well-being and distress.

RESULTS

As predicted, regression analyses showed that conspiracy mentality is negatively associated with perceived control and indicators of psychological well-being, and positively associated with insomnia and indicators of psychological distress 1 month later. The results of structural equation modeling and bootstrapping analyses provided empirical support to our theoretical model that perceived control and insomnia serially mediate the relationship between conspiracy mentality and both psychological well-being and psychological distress.

CONCLUSIONS

These findings offer important contributions to the literature on conspiracy beliefs. Practically, they offer potential routes of intervention to weaken insomnia and psychological distress and enhance psychological well-being.

(Why) Is Misinformation a Problem?

In the last decade there has been a proliferation of research on misinformation. One important aspect of this work that receives less attention than it should is exactly why misinformation is a problem. To adequately address this question, we must first look to its speculated causes and effects. We examined different disciplines (computer science, economics, history, information science, journalism, law, media, politics, philosophy, psychology, sociology) that investigate misinformation. The consensus view points to advancements in information technology (e.g., the Internet, social media) as a main cause of the proliferation and increasing impact of misinformation, with a variety of illustrations of the effects. We critically analyzed both issues. As to the effects, misbehaviors are not yet reliably demonstrated empirically to be the outcome of misinformation; correlation as causation may have a hand in that perception. As to the cause, advancements in information technologies enable, as well as reveal, multitudes of interactions that represent significant deviations from ground truths through people's new way of knowing (intersubjectivity). This, we argue, is illusionary when understood in light of historical epistemology. Both doubts we raise are used to consider the cost to established norms of liberal democracy that come from efforts to target the problem of misinformation.

A longitudinal analysis of conspiracy beliefs and Covid-19 health responses

BACKGROUND

Little is known about how conspiracy beliefs and health responses are interrelated over time during the course of the coronavirus disease 2019 (Covid-19) pandemic. This longitudinal study tested two contrasting, but not mutually exclusive, hypotheses through cross-lagged modeling. First, based on the consequential nature of conspiracy beliefs, we hypothesize that conspiracy beliefs predict an increase in detrimental health responses over time. Second, as people may rationalize their behavior through conspiracy beliefs, we hypothesize that detrimental health responses predict increased conspiracy beliefs over time.

METHODS

We measured conspiracy beliefs and several health-related responses (i.e. physical distancing, support for lockdown policy, and the perception of the coronavirus as dangerous) at three phases of the pandemic in the Netherlands (N = 4913): During the first lockdown (Wave 1: April 2020), after the first lockdown (Wave 2: June 2020), and during the second lockdown (Wave 3: December 2020).

RESULTS

For physical distancing and perceived danger, the overall cross-lagged effects supported both hypotheses, although the standardized effects were larger for the effects of conspiracy beliefs on these health responses than vice versa. The within-person change results only supported an effect of conspiracy beliefs on these health responses, depending on the phase of the pandemic. Furthermore, an overall cross-lagged effect of conspiracy beliefs on reduced support for lockdown policy emerged from Wave 2 to 3.

CONCLUSIONS

The results provide stronger support for the hypothesis that conspiracy beliefs predict health responses over time than for the hypothesis that health responses predict conspiracy beliefs over time.

From Conspiracy to Hesitancy: The Longitudinal Impact of COVID-19 Vaccine Conspiracy Theories on Perceived Vaccine Effectiveness

The embrace of coronavirus disease 2019 (COVID-19) vaccine conspiracies has been linked to vaccine hesitancy. This study aimed to investigate the relationship between COVID-19 vaccine conspiracy theories and perceived vaccine effectiveness. The study utilized a longitudinal follow-up study in which adults in Chile completed surveys in December 2020 (T1) and May 2021 (T2). The psychometric properties of the five-item instrument on conspiracy theories for the COVID-19 vaccine were evaluated using data from T1 (n = 578). A confirmatory one-factor structure with suitable indicators of reliability was found. The longitudinal analysis (n = 292) revealed that conspiracy theories about the COVID-19 vaccine in T1 were associated with lower beliefs in its effectiveness in T2. However, no significant association was found between beliefs in effectiveness in T1 and conspiracy theories in T2. The study suggests that beliefs in conspiracy theories may temporally precede beliefs in vaccine effectiveness for COVID-19. The results have implications for strategies to address vaccine conspiracy beliefs and their implementation at the public policy level.

Unlocking infodemics and mysteries in COVID-19 vaccine hesitancy: Nexus of conspiracy beliefs, digital informational support, psychological Well-being, and religious fatalism

Guarding against an anti-science camouflage within infodemics is paramount for sustaining the global vaccination drive. Vaccine hesitancy remains a growing concern and a significant threat to public health, especially in developing countries. Infodemics, conspiracy beliefs and religious fatalism primarily fuel vaccine hesitancy. In addition, anti-vaccine disinformation, lack of understanding, and erroneous religious beliefs also trigger vaccine hesitancy. Global behavioral strategies such as wearing face masks and long-term preventive measures (i.e., COVID-19 vaccination) have effectively limited the virus's spread. Despite the alarming rate of global deaths (i.e., over 99% being unvaccinated), a large proportion of the global population remains reluctant to vaccinate. New evidence validates the usefulness of technology-driven communication strategies (i.e., digital interventions) to address the complex socio-psychological influence of the pandemic. Hence, the present research explored the digital information processing model to assess the interface between informational support (through digital interventions) and antecedents of vaccine hesitancy. This research involved two separate studies: a focus group to operationalize the construct of infodemics, which remained ambiguous in previous literature (Study 1), followed by a cross-sectional survey (Study 2) to examine the conceptual model. Data were collected from 1906 respondents through a standard questionnaire administered online. The focus group's findings revealed a multi-dimensional nature of infodemics that was also validated in Study 2. The cross-sectional survey results substantiated infodemics, religious fatalism and conspiracy beliefs as significant predictors of vaccine hesitancy. Similarly, conspiracy beliefs negatively influence an individual's psychological well-being. Furthermore, information support (through digital intervention) affected infodemics and religious fatalism, whereas it inversely influenced the strength of their relationships with vaccine hesitancy. Information support (through digital intervention) also moderated the relationship between conspiracy beliefs and psychological well-being.

The mediating role of vaccine hesitancy in the relations of COVID-19 conspiracy beliefs and vaccination outcomes: Which dimensions matter?

COVID-19 conspiracy beliefs have a powerful detrimental influence on COVID-19 vaccine perceptions and behaviors. We investigate an expanded range of outcomes for COVID-19 conspiracy beliefs, and we test which vaccine hesitancy dimensions mediate these relations. Our results show that COVID-19 conspiracy beliefs relate to COVID-19 vaccination willingness and receipt, flu vaccination willingness and receipt, as well as vaccine word-of-mouth. Many of these relations are mediated by vaccine hesitancy dimensions that represent perceptions that vaccines pose health risks as well as perceptions that vaccines are not needed because the respondent is healthy. Our discussion identifies directions for future research.

Contemporary trends in psychological research on conspiracy beliefs. A systematic review

Background

The number of psychological studies on conspiracy beliefs has been systematically growing for about a dozen years, but in recent years, the trend has intensified. We provided a review covering the psychological literature on conspiracy beliefs from 2018 to 2021. Halfway through this period, the COVID-19 pandemic broke out, accompanied by an explosion of movements based on conspiracy theories, intensifying researchers' interest in this issue.

Methods

Adhering to PRISMA guidelines, the review systematically searched for relevant journal articles published between 2018 and 2021. A search was done on Scopus and Web of Science (only peer-reviewed journals). A study was included if it contained primary empirical data, if specific or general conspiracy belief(s) were measured and if its correlation with at least one other psychological variable was reported. All the studies were grouped for the descriptive analysis according to the methodology used, the participants' characteristics, the continent of origin, the sample size, and the conspiracy beliefs measurement tools. Due to substantial methodological heterogeneity of the studies, narrative synthesis was performed. The five researchers were assigned specific roles at each stage of the analysis to ensure the highest quality of the research.

Results

Following the proposed methodology, 308 full-text articles were assessed for eligibility and 274 articles (417 studies) meeting the inclusion criteria were identified and included in the review. Almost half of the studies (49.6%) were conducted in European countries. The vast majority of the studies (85.7%) were carried out on samples of adult respondents. The research presents antecedents as well as (potential) consequences of conspiracy beliefs. We grouped the antecedents of conspiracy beliefs into six categories: cognitive (e.g., thinking style) motivational (e.g., uncertainty avoidance), personality (e.g., collective narcissism), psychopathology (e.g., Dark Triad traits), political (e.g., ideological orientation), and sociocultural factors (e.g., collectivism).

Conclusion and limitations

The research presents evidence on the links between conspiracy beliefs and a range of attitudes and behaviors considered unfavorable from the point of view of individuals and of the society at large. It turned out that different constructs of conspiracy thinking interact with each other. The limitations of the study are discussed in the last part of the article.

Declared Intention to Vaccinate against COVID-19 and Actual Vaccination-The Role of Trust in Science, Conspiratorial Thinking and Religiosity

AIMS

The study aims to investigate how trust in science, conspiratorial thinking, and religiosity affected people's declared willingness to vaccinate against COVID-19 at the onset of the vaccination program in Poland, their actual vaccination, and the consistency between intention and vaccination.

METHODS

In a longitudinal design, a representative sample of 918 members of the Polish general population was polled at the beginning of the vaccination program (February 2021) and polled again after 6 months of mass vaccination (August 2021). We measured the willingness to vaccinate, actual vaccination after 6 months, and individual variables-trust in science, conspiratorial thinking and religiosity.

RESULTS

The actual vaccination rate was higher than the declared intent, especially in the initially undecided and unwilling groups. Higher Trust in science and lower Conspiratorial Thinking were associated with declared intent to vaccinate and actual vaccination, while Religiosity was not clearly associated with vaccination.

CONCLUSIONS

Declared willingness to vaccinate is not an effective indicator of actual vaccination. Trust in science and Conspiratorial thinking are important factors associated with vaccine hesitancy. There may be a possibility to influence those unwilling to vaccinate and that are undecided to eventually get vaccinated.

Knowledge, Attitude and Conspiracy Beliefs of Healthcare Workers in Lebanon towards Monkeypox

The emergence of a monkeypox (MPOX) outbreak in 2022 represented the most recent recognizable public health emergency at a global level. Improving knowledge and attitude towards MPOX, particularly among healthcare workers (HCWs), can be a valuable approach in public health preventive efforts aiming to halt MPOX virus spread. The aim of the current study was to evaluate the knowledge and attitude of HCWs in Lebanon towards MPOX and to assess their conspiratorial attitude towards emerging virus infections (EVIs). The current study was based on a cross-sectional online survey distributed via Google Forms during September-December 2022 implementing a convenience sampling approach. The final study sample comprised a total of 646 HCWs: physicians (n = 171, 26.5%), pharmacists (n = 283, 43.8%), and nurses (n = 168, 26.0%), among others (n = 24, 3.7%). Variable defects in MPOX knowledge were detected, with a third of the participants having MPOX knowledge above the 75th percentile (n = 218, 33.7%). Satisfactory attitude towards MPOX (>75th percentile) was observed in less than a third of the participants (n = 198, 30.7%), while a quarter of the study sample endorsed conspiracy beliefs towards EVIs at a high level (>75th percentile, n = 164, 25.4%). Slightly more than two thirds of the participants agreed that MPOX vaccination should be used in disease prevention (n = 440, 68.1%). Better levels of MPOX knowledge and attitude were significantly associated with postgraduate education and older age. Physicians had significantly higher MPOX knowledge compared to other occupational categories. Less endorsement of conspiracies towards EVIs was significantly associated with male sex, occupation as a physician, and postgraduate education. Higher MPOX knowledge was associated with better attitude towards the disease. The current study showed unsatisfactory MPOX knowledge among Lebanese HCWs. Educational efforts can be valuable to improve the attitude towards the disease. Despite the relatively low level of embracing conspiracy beliefs regarding EVIs among HCWs in this study compared to previous studies, this area should be considered based on its potential impact on health-seeking behavior.

Individual, intergroup and nation-level influences on belief in conspiracy theories

Conspiracy theories are part of mainstream public life, with the potential to undermine governments, promote racism, ignite extremism and threaten public health efforts. Psychological research on conspiracy theories is booming, with more than half of the academic articles on the topic published since 2019. In this Review, we synthesize the literature with an eye to understanding the psychological factors that shape willingness to believe conspiracy theories. We begin at the individual level, examining the cognitive, clinical, motivational, personality and developmental factors that predispose people to believe conspiracy theories. Drawing on insights from social and evolutionary psychology, we then review research examining conspiracy theories as an intergroup phenomenon that reflects and reinforces societal fault lines. Finally, we examine how conspiracy theories are shaped by the economic, political, cultural and socio-historical contexts at the national level. This multilevel approach offers a deep and broad insight into conspiracist thinking that increases understanding of the problem and offers potential solutions.

Professions and inequality: challenges, controversies, and opportunities

On the basis of the EGOS 2021 sub-plenary on ‘Professions and Inequality: Challenges, Controversies, and Opportunities’, the presenters and panellists wrote four short essays on the relationship between inequality as a grand challenge and professional occupations and organizations, their structures, practices, and strategies. Individually, these essays take an inquisitorial stance on extant understandings of (1) how professions may exacerbate existing inequalities and (2) how professions can be part of the solution and help tackle inequality as a grand challenge. Taken together, the discussion forum aims at advancing scholarly debates on inequality by showing how professions’ scholarship may critically interrogate extant understandings of inequality as a broad, multifaceted concept, whilst providing fruitful directions for research on inequality, their potential solutions, and the role and responsibilities of organization and management scholars.

Conspiracy mentality among informal caregivers as a risk factor for caregiver burden, mental health, perceived loneliness and social isolation during the COVID-19 pandemic: findings of a representative online study from Germany

PURPOSE

This study aims to analyze if and how conspiracy mentality is associated with mental health, burden and perceived social isolation and loneliness of informal caregivers of older individuals with care needs.

METHODS

A quantitative, cross-sectional study was conducted. Participants had to be at least 40 years of age and were drawn randomly from the German online panel forsa.omninet and questioned between the 4th and 19th of March 2021. A sample of 489 informal caregivers (relatives and non-relatives supporting individuals aged ≥ 60 years) was questioned. Conspiracy mentality, depressive symptoms, loneliness and social exclusion were measured with validated instruments (e.g., The Conspiracy Mentality Questionnaire). Questions referred to the last three months prior to assessment. Multiple linear regression analyses, adjusted for sociodemographic, economic and health factors and indicators of the pandemic, were conducted.

RESULTS

Findings indicate a significant positive association between conspiracy mentality and caregiver burden, loneliness, social exclusion, and depressive symptoms. No gender differences were found for any outcome.

CONCLUSIONS

The results indicate that conspiracy mentality could be a risk factor for mental health, perceived social isolation and loneliness, and contribute to increased caregiver burden among informal caregivers of older care recipients during the COVID-19 pandemic. Accordingly, informal caregivers could benefit from actions focused on reducing conspiracy mentality during a health crisis, which could improve psychosocial health and wellbeing in this vulnerable group.

Psychological benefits of believing conspiracy theories

Many people believe conspiracy theories, even though such beliefs are harmful to themselves and their social environment. What is the appeal of conspiracy theories? In this contribution, I propose that conspiracy theories have psychological benefits by imbuing perceiver's worldview with meaning and purpose in a rewarding manner. Conspiracy theories enable an alternative reality in which perceivers (a) can defend a fragile ego by perceiving themselves and their groups as important, (b) can rationalize any of their beliefs and actions as legitimate, and (c) are entertained through the opportunity to uncover a mystery in an exciting tale. These are short-term benefits, however, suggesting that conspiracy theories provide people with a form of instant gratification.

Shining a spotlight on the dangerous consequences of conspiracy theories

The COVID-19 pandemic has illuminated how conspiracy beliefs–that explain important events as the secret actions of the powerful–can severely impact health choices (such as reduced infection-prevention behaviours). However, the consequences of conspiracy beliefs span far beyond the topic of COVID-19. This review shines a spotlight on how conspiracy beliefs could impact public and personal health (e.g., vaccine uptake), democratic citizenship (e.g., political engagement), intergroup relations (e.g., prejudice and discrimination), and may inspire violence and extremism. We argue that conspiracy beliefs are likely to have the power to mobilise citizens in ways detrimental to a smooth-running society. We conclude the review by offering a range of fruitful avenues for future investigation.

Social Media, Public Health, and Community Mitigation of COVID-19: Challenges, Risks, and Benefits

Shortly after the first case reports in 2019, COVID-19 was declared a pandemic. Early messages from trusted experts, which later proved to be inadequate or incorrect, highlight the need for continual adjustment of messages to the public as scientific knowledge evolves. During this time, social media exploded with greatly sought-after information, some of which was misinformation based on incomplete or incorrect facts or disinformation purposefully spread to advance a specific agenda. Because of the nature of social media, information, whether accurate or not at the time posted, lives on and remains accessible to the public even when its usefulness has been discredited. While the impact of mis/disinformation on COVID-19 risk-reducing behaviors is debatable, it is clear that social media has played a significant role in both extending the reach of COVID-19-related falsehoods and promoting evidence-based content. Over the last decade, social media has become a dominant source of information that consumers turn to for health information. A great deal of misinformation and disinformation has reached large numbers of social media users, which points to a need for the agencies of the US Public Health Service to create communications to convey accurate and current information and appeals that will actually be viewed. This viewpoint highlights the challenges, risks, and potential benefits that social media present in mitigating the COVID-19 pandemic.

The relation between conspiracism, government trust, and COVID-19 vaccination intentions: The key role of motivation

Rationale

Vaccination willingness is a critical step in the effort to reach herd immunity and control the COVID-19 pandemic. Nevertheless, many people remain reluctant to be vaccinated.

Objective

Integrating the literature on Self-Determination Theory, trust in authorities, and conspiracy theories, this research examines (a) the direct and indirect effect of government trust and conspiracism via underlying forms of motivations for (not) getting vaccinated against COVID-19 and (b) whether these associations differ across the two largely politically independent Belgian linguistic groups.

Methods

Using Structural Equation Modeling, we tested our models in two independent samples, in February 2021 (T1) and April 2021 (T2) (Total N = 8264).

Results

At T1 and T2, Government trust and conspiracism both predict COVID-19 vaccination intention, respectively positively and negatively. These relations are fully mediated by motivational factors, with identified motivations having a larger positive contribution. Looking at linguistic context, differences emerge at T2, with French-speaking Belgians showing lower levels of government trust and higher levels of conspiracism than Dutch speakers.

Conclusions

Results highlight the importance of integrating distal (trust in government, conspiracism) and proximal (motivational) variables to understand vaccination intentions.
