Upon the sudden outbreak of COVID-19 pandemic, various conspiracy theories regarding the virus proliferated in the social media. This study focused on the sociodemographic, personality, and moral predictors of these beliefs. More specifically, we asked whether moral values predict belief in COVID-19 conspiracy theories over and above sociodemographic variables and the Big Five personality traits. According to Moral Foundations Theory, five cross-cultural moral foundations are more broadly categorized under individualizing (Care & Fairness) and binding (Loyalty, Authority, & Sanctity) foundations. A sixth moral foundation was Liberty which we included along with binding and individualizing foundations. Participants were 227 Iranians (mean age = 31.43, SD = 12.61, 75.3% female) who responded to Moral Foundations Questionnaire and Liberty items, a range of COVID-19 conspiracy beliefs, and the 10-Item Personality Measure of the Big Five. Among demographic variables, religiosity and socioeconomic status were the strongest determinants of conspiracy beliefs regarding the origin of Coronavirus. Among the Big Five, only extraversion predicted these beliefs in a positive direction. Moral foundations, most notably Authority and Sanctity, showed incremental predictive power over both demographic variables and the Big Five personality traits. Findings are discussed in light of the role of social media in dissemination of conspiracy beliefs regarding the pandemic. They point to the more relevance of moral foundations, particularly binding foundations, than the Big Five in the context of pandemic-related conspiracy beliefs, and add to the literature on the unique contribution of moral foundations to socio-political attitudes across cultures.
1. Introduction
In December 2019, the world was shocked by the news on emergence of a cold-like disease in Wuhan, China, and the subsequent lockdown due to that. The World Health Organization published the first announcement about the virus, named as COVID-19, on January 5, 2020, and declared it a pandemic on March 11 (World Health Organization, 2020). The first deaths in Iran were reported on Feb 19, followed by a rapid spread of the disease, such that in April, 2020 it ranked sixth among world countries in total COVID-19 deaths (Nikpouraghdam et al., 2020).
The pandemic led to a substantial increase in information seeking concerning the disease (e.g., Casero-Ripollés, 2020), with certain beliefs spreading through the social media, and giving rise to an “infodemic” in parallel to the pandemic (Infodemic, 2020). Examples include a China-produced bioweapon and links to Internet 5G or Bill Gates (Shahsavari et al., 2020). The Infodemic Risk Index, a measure of exposure to unreliable news via Twitter, was found to be particularly high in Iran (Gallotti et al., 2020). Later, beliefs similar to the ones concerning origin of the virus targeted vaccination. In September 2021, skepticism about the vaccine was the first among the two main reasons underlying lack of interest in getting vaccinated among Iranians (Iranian Students Poll Agency, 2021). The present study seeks to shed light on the sociodemographic, personality, and moral underpinnings of these pandemic-related beliefs in Iran.
Beliefs similar to the ones mentioned in relation to COVID-19 have existed in the literature under the title of conspiracy theories (Goertzel, 1994; Zonis and Joseph, 1994; Aaronovitch, 2010). Generally defined as a set of beliefs providing explanations about ultimate causes of a significant social event by attributing them to mostly powerful agents (Dentith and Orr, 2017), conspiracy theories have long constituted part of the human history, and are particularly likely to show up in response to social crises (Van Prooijen and Douglas, 2017). The sudden outbreak of COVID-19 with its noticeable impact on social life worldwide represented one such event. COVID conspiracy theories entail various beliefs regarding the artificiality or exploitation of the virus (Freeman et al., 2020;Imhoff and Lamberty, 2020; Karić and Međedović, 2021), and centering around malevolent groups pursuing specific objectives, or governments taking advantage of it to advance anti-democratic goals (Oleksy et al., 2021). The beliefs have been linked to low education, young age and low income (Romer and Jamieson, 2020), and lead to more spread of the disease through less commitment to preventive behaviors (Imhoff and Lamberty, 2020; Karić and Međedović, 2021). As such, identifying determinants of these beliefs bears significant practical implications.
As a culture-sensitive theory in moral psychology, Moral Foundations Theory (Haidt and Joseph, 2004; Graham et al., 2013) distinguished between five flavors of moral intuition underpinning moral judgment. Moral foundations include Care/Harm, Fairness/Cheating, Loyalty/Betrayal, Authority/Subversion, and Sanctity/Degradation, more broadly categorized under individualizing (Care and Fairness) and binding (Loyalty, Authority, and Sanctity) foundations (Graham et al., 2011; Nejat and Hatami, 2019). A sixth foundation, namely Liberty/Oppression, was proposed later by Iyer et al. (2012). We also included this rather understudied moral foundation in this study along with individualizing and binding foundations.
The focus on ingroup survival underlying binding foundations (Graham et al., 2011), is congruent with the “us vs. them” mentality inherent in most conspiracy beliefs (Van Prooijen and Van Lange, 2014). Further, conspiracy-evoking events are usually considered as a threat to the society (Leone et al., 2019), thus tapping on the motive to conserve the group. Consistently, binding and individualizing foundations had positive and negative relations with conspiracy beliefs, respectively, with binding foundations more strongly relating to these beliefs (Leone et al., 2019). Similarly, more concern with moral purity, as reflected in sexual and dietary prohibitions, predicted higher endorsement of COVID conspiracy beliefs in Finland (Pivetti et al., 2021), while Nestik and Deyneka (2020) found positive associations between COVID conspiracy beliefs and endorsement of Loyalty and Authority in Russia. Finally, endorsement of Care and Fairness predicted higher trust in science and government (Pagliaro et al., 2021). Considering the skepticism of conspiracy theories toward official accounts of events (Connolly et al., 2019), including those originating from scientists or governments, as well as empirical findings suggesting a negative link between trust in science/government and COVID conspiracy beliefs (Freeman et al., 2020; Kim and Kim, 2021; Vranic et al., 2022), more reliance on Care and Fairness may be argued to counteract conspiratorial thinking through higher trust in science/government. Accordingly, we anticipate a positive relation between binding foundations and COVID conspiracy beliefs, and a negative association between individualizing foundations and these beliefs, with a more salient role for binding foundations.
Empirical evidence supports incremental predictive power of moral foundations beyond a number of variables, e.g., beyond Schwartz values in predicting attitude toward social groups (Graham et al., 2011), beyond core motives in predicting general political orientation (Yilmaz and Saribay, 2019), and beyond personal values of self-enhancement/self-transcendence and openness to change/conservation in predicting behavior and attitudes (Feldman, 2021). The current study aims to contribute to this literature by examining incremental predictive power of moral foundations beyond the Big Five of personality (McCrae and Costa, 1999), namely extraversion, agreeableness, conscientiousness, neuroticism (also called emotional stability, its reverse), and openness to experience, in determining conspiracy beliefs surrounding COVID-19.
The Big Five traits may be argued to contribute in distinct ways to the motives (Douglas et al., 2019) underlying conspiracy beliefs (hereafter referred to as our ‘motives account’). More specifically, given that neuroticism entails heightened reaction to stress, it may thus strengthen the existential (security and control) motive, functioning to drive conspiracy beliefs. Conversely, the trust and optimism underpinning agreeableness would possibly reduce the salience of this motive, resulting in less proneness to conspiracy theories. Extraverts’ concern with social relationships may contribute to the importance of the social (maintaining positive image of self and ingroup) motive to them, rendering them prone to conspiracy beliefs. Given the link between conspiracy beliefs and the need for cognitive closure (e.g., Marchlewska et al., 2018), indicative of the epistemic (understanding) motive (Douglas et al., 2019), openness to experience, an opposite of tendency for closure, can be expected to predict less vulnerability to conspiracies. Finally, despite the high-conscientious’ interest in order and accuracy, their lack of impulsivity would lead them to seek more rational means than conspiracy beliefs in order to satisfy epistemic (understanding) needs. In sum, we expect neuroticism and extraversion to relate positively, but agreeableness, conscientiousness, and openness to relate negatively to conspiracy beliefs.
Empirical evidence suggests contribution of the Big Five to COVID-related stress and anxiety (Bellingtier et al., 2021; Nikčević et al., 2021; Pérez-Mengual et al., 2021; Zacher and Rudolph, 2021; Lassen et al., 2022). Given the positive link between anxiety/stress and COVID conspiracy beliefs (Sallam et al., 2020; Hartman et al., 2021; Barahmand et al., 2022; Pfeffer et al., 2022; Šrol et al., 2022; Liekefett et al., 2023), the Big Five may also serve as predictor of COVID conspiracy beliefs. Common predictors among the above-cited studies are neuroticism and extraversion. They converged on the higher vulnerability of high-neurotic individuals to COVID anxiety/stress, while partly disagreeing on the role of extraversion. Whereas some found extraversion a protective factor against COVID-related worry/anxiety (Nikčević et al., 2021; Pérez-Mengual et al., 2021; Lassen et al., 2022), others reported opposing relations for different timespans (Zacher and Rudolph, 2021) or facets (Bellingtier et al., 2021). Taken together, relying on anxiety/stress as the mechanism underlying the relationship between the Big Five and conspiracy beliefs (hereafter referred to as our ‘stress account’), whereas neuroticism may be expected to positively predict COVID conspiracy beliefs, there is more ambiguity regarding the role of extraversion.
The literature on the association between conspiracy beliefs and the Big Five also contains inconsistencies. Whereas some found positive relations between conspiracy beliefs and openness (Swami and Furnham, 2012; Swami et al., 2013; Charlton, 2014), agreeableness (Swami et al., 2010; Orosz et al., 2016), and conscientiousness (Swami and Furnham, 2012; Charlton, 2014; Arnulf et al., 2022), others reported negative relations between these beliefs and openness (Orosz et al., 2016), agreeableness (Swami and Furnham, 2012; Charlton, 2014; Bowes et al., 2021; Arnulf et al., 2022), and conscientiousness (Brotherton et al., 2013; Bowes et al., 2021). However, the reported significant relations between conspiracy beliefs and neuroticism or extraversion all converged on positive associations with both neuroticism (Swami and Furnham, 2012; Swami et al., 2013; Charlton, 2014; Hollander, 2018; Heiss et al., 2021) and extraversion (Heiss et al., 2021; Arnulf et al., 2022). Nevertheless, the majority of the cited studies addressed non-COVID conspiracy theories. Given the distinct nature of the recent pandemic, such as reduced social contact and individuals’ over-reliance on social media as a result of that, different findings may emerge regarding the conspiracy beliefs relating to it. In response to the presented gaps with respect to the Big Five, as well as the small number of studies examining the link between moral foundations and COVID conspiracy beliefs, this study aimed to investigate the role of the Big Five traits and moral foundations as determinants of COVID-19 conspiracy beliefs in an understudied non-Western context, with expectation of more salient roles for binding foundations, neuroticism, and extraversion.
2. Methods
2.1. Participants
Participants were 253 Iranians who were recruited through social media, and responded to the survey via an Iranian survey-hosting website during April–June 2021. 26 participants were excluded due to incorrect responses to the attention check, leaving a final sample of N = 227 (mean age = 31.43, SD = 12.61, 75.3% female) ranging in age from 17 to 71 years. The majority of participants already had or were pursuing a Bachelor’s degree (61.7%), followed by Master’s or M.D. (17.7%), primary or high school (15.4%), and Ph.D. (5.3%). This study received approval of the departmental review board, and informed consent was obtained from all participants.
2.2. Materials
2.2.1. Moral foundations and Liberty
The Persian translation (Nejat and Hatami, 2019) of the 20-item Moral Foundations Questionnaire (MFQ-20; Graham et al., 2011) was used to assess endorsement of Care, Fairness, Loyalty, Authority, and Sanctity. MFQ consists of relevance and judgment sections, and each moral foundation is represented by two items in each section. Responses ranged from 0 (Not at all important) to 5 (Extremely important), and from 0 (Strongly disagree) to 5 (Strongly agree) for relevance and judgment, respectively. Omega coefficients were Care 0.37, Fairness 0.65, Loyalty 0.64, Authority 0.70, and Sanctity 0.68. Due to the Care’s low internal consistency, Care and Fairness were aggregated to form individualizing foundations (ω = 0.68) whereas Loyalty, Authority, and Sanctity constituted the binding foundations (ω = 0.84). The Persian translation (Nejat and Hatami, 2019) of seven out of the nine items proposed by Iyer et al. (2012) was used to assess Liberty, consisting of two relevance and five judgment items (ω = 0.66).
2.2.2. Belief in COVID-19 conspiracy theories
A pool of 34 items was accumulated from a set of relevant studies (Freeman et al., 2020; Imhoff and Lamberty, 2020; Olatunji et al., 2020; Eberl et al., 2021; Karić and Međedović, 2021) with responses ranging from 1 (Strongly disagree) to 5 (Strongly agree). To arrive at the final measure, we gathered the whole set of items through the cited studies, identified redundant ones across scales, and excluded the ones decided as the most irrelevant to the context of our culture and country based on judgment of the principal investigator and two lab assistants. The final set of items were categorized as the following based on their content: Lockdown (three items, α = 0.71), Vaccination (three items, α = 0.83), Virus origin (21 items, α = 0.93), Exploitation of COVID for other purposes (three items, α = 0.78), and News accuracy (four items, α = 0.62). Sample items include “The intention of lockdown is to force people to rely on big corporations rather than local businesses” (Lockdown), “The coronavirus vaccine contains microchips to control people” (Vaccination), “The spread of the virus is a deliberate attempt to reduce the size of the global population” (Virus origin), “Coronavirus is a news only to divert attention from more important things” (Exploitation), and “The mainstream media is deliberately feeding us misinformation about the virus and lockdown” (News accuracy). Six reverse-scored items referred to formal facts regarding COVID, four of them in the virus origin, e.g., “The virus is naturally occurring,” and two in news accuracy. The full set of items is presented in Supplementary materials. Cronbach alpha for the whole set of items was 0.95. Confirmatory factor analysis of a five-correlated-factor model yielded CFI = 0.77, RMSEA = 0.097, and CMIN/df = 3.11, with regression weights all significant, ps < 0.05.
2.2.3. The Big Five
We used the Persian translation (Azkhosh et al., 2019) of the 10-Item Personality Inventory (TIPI; Gosling et al., 2003). Each dimension of the Big Five was represented by two items with responses ranging from 1 (Strongly disagree) to 5 (Strongly agree). Cronbach alphas were Extraversion 0.70, Agreeableness 0.34, Conscientiousness 0.56, Emotional Stability 0.37, and Openness to Experience 0.43. Studies have reported similarly low alphas for this scale, e.g., 0.40–0.73 (Gosling et al., 2003), 0.40–0.69 (Azkhosh et al., 2019), and 0.38–0.61 (Romero et al., 2012). Gosling et al. (2003) justified the use of this scale, despite mediocre internal consistency, by prioritizing content validity through minimum number of items, and satisfactory test–retest reliability and validity.
2.2.4. Demographics
Participants reported their age, gender, political orientation (from 1 = “Very principlist” to 5 = “Very reformist”), religiosity (from 1 = “Not at all or very little” to 5 = “Very much”), and socioeconomic status (SES; from 1 = “Very lower than average” to 5 = “Very higher than average”).
3. Results
3.1. Correlations
Individualizing moral foundations were inversely correlated only with beliefs on news accuracy, whereas binding moral foundations were positively correlated with all conspiracy belief categories except news accuracy. Liberty had negative but weak correlations with all belief categories (Table 1). Extraversion was positively correlated only with virus origin beliefs, while the remaining four Big Five dimensions were not significantly related to any of the belief categories. Regarding sociodemographics, political orientation was negatively correlated with vaccination, origin, and exploitation beliefs, while religiosity was positively related to all belief categories, and SES was not significantly correlated with any of the belief categories, but marginally related to lockdown, p = 0.054, vaccination, p = 0.054, and exploitation, p = 0.061. Age was not significantly related to any of the belief categories. The few significant correlations between moral foundations and the Big Five were all weak in size, rs < 0.24.
Table 1. Descriptive statistics and zero-order correlations between COVID conspiracy beliefs, moral foundations, the Big Five, and sociodemographic variables.
3.2. Incremental predictive power of moral foundations
Except the weak correlations between extraversion and total COVID conspiracy beliefs, r = 0.15, p = 0.026, and between extraversion and origin conspiracy beliefs (Table 1), all other correlations between the Big Five and total conspiracy beliefs, rs < 0.08, ps > 0.27, or the belief categories, ps > 0.095, were non-significant. Given that the strongest correlation involved origin conspiracy beliefs, we used this category of beliefs as the criterion variable. We conducted a hierarchical regression analysis entering demographic variables in the first step, followed by the Big Five and moral foundations in the second and third steps, respectively (Table 2). We entered binding foundations as separate moral foundations in this analysis in order to gain a more detailed picture of their relationship with conspiracy beliefs. As revealed, highly religious individuals endorsed more origin conspiracy beliefs. Among personality factors, only extraversion, with a positive coefficient, was a significant predictor of origin conspiracy beliefs. The change in explained variance due to personality factors was not significant, F(5, 216) = 1.69, p = 0.138. Among moral foundations, Sanctity and Authority were significant positive predictors. The significant change in R square in step 3, F(5, 211) = 4.78, p < 0.001, indicated the incremental predictive power of moral foundations beyond both demographic variables and the Big Five. The final step also included socioeconomic status (SES) as a significant negative predictor.
Table 2. Hierarchical regression analysis with sociodemographic variables, the Big Five, and moral foundations as predictors of virus origin conspiracy beliefs.
A similar hierarchical regression analysis with total COVID conspiracy beliefs as the criterion variable yielded a non-significant, F(5, 216) = 1.10, p = 0.359, and significant, F(5, 211) = 5.08, p < 0.001, changes in R square by adding the Big Five and moral foundations to the model, respectively. Across the three steps, religiosity, 0.19 < βs < 0.36, ps < 0.05, and SES, −0.16 < βs < −0.14, ps < 0.05, were positive and negative predictors of conspiracy beliefs, respectively. Extraversion was a marginally significant positive predictor in both the second, β = 0.12, SE = 0.04, p = 0.072, and the third, β = 0.11, SE = 0.04, p = 0.088, steps. Among moral foundations, only Sanctity, β = 0.20, SE = 0.06, p = 0.020, and Authority, β = 0.26, SE = 0.06, p = 0.002, turned out as significant predictors of total COVID conspiracy beliefs, both in the positive direction. All other coefficients were non-significant, |β|s < 0.11, ps > 0.10.
4. Discussion
As expected, binding foundations tended to have stronger relationships with COVID conspiracy beliefs than both individualizing foundations and Liberty. Further, moral foundations explained both total COVID conspiracy beliefs, and more specifically, conspiracy beliefs regarding the virus origin, beyond sociodemographic characteristics and the Big Five, thereby adding to the literature on incremental predictive power of moral foundations, also complementing it by including the understudied moral foundation of Liberty. More specifically, higher reliance on Authority and Sanctity predicted more endorsement of COVID conspiracy beliefs, a finding consistent with current evidence on the association between binding foundations and conspiracy beliefs (Leone et al., 2019; Nestik and Deyneka, 2020; Pivetti et al., 2021). Although we also expected Loyalty (Nestik and Deyneka, 2020) and individualizing foundations (Leone et al., 2019; Pagliaro et al., 2021) to predict conspiracy beliefs, our findings revealed a more salient role for Authority and Sanctity. Individuals relying more heavily on Authority to whom deference to authority figures is essential, may be particularly willing to gain control amid the pandemic by securing a role for the high-powered, as generally indicated by conspiracy beliefs (Dentith and Orr, 2017). Moreover, individuals high in Sanctity who are particularly tuned at purity concerns (Graham et al., 2013), may be subscribing to conspiracy beliefs in order to dismiss the prospect of contamination by either the virus itself or the formal measures associated with that, e.g., use of chemical drugs or vaccines.
The Big Five traits did not emerge as strong predictors of conspiracy beliefs, with only more extraverted individuals reporting higher endorsement of beliefs regarding the COVID origin, as expected based on both our proposed relation between extraversion and the social motive, and prior empirical evidence on the association between extraversion and conspiracy beliefs (e.g., Heiss et al., 2021; Arnulf et al., 2022). This finding is also in line with the large array of studies suggesting a more salient role for extraversion in prediction of social media use compared to the remaining four Big Five dimensions. Extraversion has been the most robust correlate of social media use followed by openness to experience and neuroticism (Correa et al., 2010; Wang et al., 2012; Liu and Campbell, 2017; Bowden-Green et al., 2020; Marengo et al., 2020), with extraverts spending more time online and having larger social networks. This can lead to their higher exposure to COVID conspiracy beliefs, especially in the context of Iran’s high Infodemic Risk Index (Gallotti et al., 2020), and result in higher endorsement of these beliefs as a consequence.
Although openness to experience has also been found to predict higher social media use (Correa et al., 2010; Liu and Campbell, 2017), its positive effect on conspiracy beliefs might have been counteracted by its negative impact on conspiracy beliefs through lower epistemic motive as suggested by our motives account. We also anticipated emotional stability to negatively predict endorsement of COVID conspiracy beliefs based on both our motives account and stress account, and similar primarily non-COVID empirical findings. Consistently, high-neurotics’ relatively high use of social media (Correa et al., 2010; Liu and Campbell, 2017; Marengo et al., 2020) indicates that they should encounter conspiracy beliefs rather frequently. The lack of support for the relationship between this dimension and conspiracy beliefs in this study may be due to high-neurotics’ tendency to avoid exposure to social media during the pandemic as a coping strategy, given the distress evoked by their content, resulting in high-neurotics’ less exposure to conspiracy beliefs.
Despite our motives-based predictions for negative relations between both agreeableness and conscientiousness and conspiracy beliefs, we found no evidence of these links, in line with the mixed or weak evidence associated with them. Some prior studies have likewise obtained less than robust associations with conspiracy beliefs across all (Brotherton et al., 2013; Bruder et al., 2013) or a selective set (agreeableness and openness; Leiser et al., 2017) of the Big Five, just as some meta-analyses failed to find strong evidence in support of this relationship (Goreis and Voracek, 2019; Stasielowicz, 2022), despite heterogeneity among studies (Stasielowicz, 2022). Three explanations may account for this finding. First, more specific personality traits such as narcissism (Gligorić et al., 2021; Sternisko et al., 2023) or schizotypal tendencies (Swami et al., 2013; Stasielowicz, 2022) may be better determinants of conspiracy beliefs than the generic Big Five. Second, conspiracy beliefs might be more substantially influenced by situational conditions, and (sub-)cultural or religious beliefs rather than personality dispositions. Third, the less than robust association between the Big Five and conspiracy beliefs may be due to the simultaneous activation of multiple mechanisms with diverging effects, as suggested for openness to experience.
Among demographics, only religiosity and SES predicted COVID conspiracy beliefs both in total and with respect to virus origin, with more religious or lower-SES individuals endorsing more of these beliefs. This resonates with prior cross-cultural findings on SES (e.g., Georgiou et al., 2020; Romer and Jamieson, 2020; Tonković et al., 2021; Hettich et al., 2022), and religiosity (e.g., Alper et al., 2021; Dyrendal and Hestad, 2021; Stasielowicz, 2022; Frenken et al., 2023). However, findings on gender and age are more inconsistent. Whereas some obtained no gender differences (Freeman et al., 2020; Dyrendal and Hestad, 2021; Tonković et al., 2021), others found women (Erceg et al., 2020; Alper et al., 2021; Vranic et al., 2022) or men (Cassese et al., 2020; Hettich et al., 2022) higher in these beliefs. Likewise, whereas some have concluded that age relates to conspiracy beliefs (Freeman et al., 2020; Romer and Jamieson, 2020; Hettich et al., 2022), others (e.g., Dyrendal and Hestad, 2021; Tonković et al., 2021; Vranic et al., 2022) found age unrelated to these beliefs, as the current study.
4.1. Limitations and future directions
One limitation of this study is its reliance on conspiracy items from non-Iranian studies. Although cultures may be expected to differ with respect to conspiracy theories, given the lack of qualitative studies specific to our culture, the decision may be justified through the inclusion of studies from various countries, and the omission of the conspiracy beliefs that we judged as irrelevant to our culture. Future researchers are recommended to explore determinants of more culturally-dependent conspiracy beliefs in addition to the universal ones.
5. Conclusion
This study examined the sociodemographic, personality, and moral determinants of COVID-19 conspiracy beliefs in the context of the Iranian culture. Findings suggest the more relevance of moral values, most notably binding foundations of Authority and Sanctity, than the Big Five traits to the way individuals respond to a pandemic in terms of conspiratorial thinking, adding to the literature on the unique contribution of moral foundations to socio-political attitudes across cultures.
