COVID-19: Why Do People Refuse Vaccination? The Role of Social Identities and Conspiracy Beliefs: Evidence from Nationwide Samples of Polish Adults

Teach them how to fish or give them fish? The effect of collective narcissism on intergroup help

Intergroup help contributes to the solution of global issues in particular. However, whether to teach an outgroup how to address their problem permanently, or to directly help them solve the current problem? Collective narcissism might play a crucial role in this process. Based on the core characteristics of collective narcissism, this research explored whether and how collective narcissism would affect people's willingness to give different types of intergroup help. Study 1 examined the correlation between collective narcissism and intergroup help. Studies 2 and 3 investigated the impacts of outgroup threat and ingroup image on the relationship between collective narcissism and intergroup help respectively. In Study 4, the interaction between outgroup threat and ingroup image was further examined. The results showed that collective narcissism reduced participants' willingness to offer intergroup help, especially autonomy-oriented help. For low-threat outgroups, collective narcissism increased participants' willingness to give dependency-oriented help. In contrast, collective narcissism increased participants' willingness to give autonomy-oriented help when refusal to intergroup help tarnished the ingroup image. For high-threat outgroups, collective narcissism did not predict participants' willingness to give intergroup help. These findings suggest that collective narcissists' preferences for intergroup help change with outgroup threat and ingroup image.

From Individual Anxiety to Collective Narcissism? Adult Attachment Styles and Different Types of National Commitment

National narcissism and national identification, two distinct types of national commitment, differ in terms of their psychological concomitants. Therefore, in the current article, we hypothesized that they would also relate to different adult attachment styles. Namely, we proposed that national narcissism would be positively associated with higher attachment anxiety, while national identification would be associated with lower attachment anxiety and avoidance. These hypotheses were tested in three cross-sectional surveys (Study 1 N = 570; Study 3 N = 558; Study 4 N = 649) and one longitudinal survey (Study 2 N = 808). In all studies, we found a consistent positive relationship between attachment anxiety and national narcissism, and a negative relationship between attachment avoidance and national identification. Finally, we also demonstrated indirect effects of attachment anxiety (via national narcissism) on maladaptive group-related outcomes: conspiracy beliefs, non-normative collective action, and willingness to conspire.

Association of National Identity and Trust in Government with COVID-19 Vaccination and Brand Choice in Taiwan

In Taiwan, hesitancy regarding COVID-19 vaccination centered more on the choice of vaccine brand than on the decision to vaccinate. However, there is limited research exploring the factors influencing COVID-19 vaccine brand preferences from a sociopolitical perspective. Thus, we aimed to examine how Taiwanese national identity and trust in government influence vaccination status and vaccine brand choice, using longitudinal data from 2020, 2021, and 2023. This study utilized data from the Taiwan Panel Study of Family Dynamics 2020 survey, and combined it with data from two self-administered surveys conducted in 2021 and 2023. We focused on four vaccines commonly administered in Taiwan: AstraZeneca, Moderna, Pfizer-BioNTech, and the domestically-developed Medigen. Using Poisson regression models with robust standard errors, we assessed the effects of national identity and trust in government on the choice of COVID-19 vaccine brand. By analyzing data from 2361 participants, we found that national identity and trust in government were associated with the likelihood of COVID-19 vaccination, the number of vaccine doses received, and the brand of vaccine taken. Those who identified themselves as Taiwanese were more inclined to receive the Medigen and AstraZeneca vaccines, but less willing to receive Pfizer-BioNTech vaccine. Those who trusted the government were more likely to prefer and receive the Medigen vaccine. Conversely, those who didn't trust the government were less likely to prefer Medigen and AstraZeneca vaccines, but were willing to receive Pfizer-BioNTech vaccine. Vaccine brand preferences and uptake in Taiwan were affected by individuals' national identity and their trust in government. This highlights the critical role of sociopolitical factors in shaping public health strategies.

Coping strategies and belief in COVID-19 conspiracy theories

Conspiracy beliefs have been related to aversive emotional experiences often accompanying major world events and have also been linked to maladaptive ways of coping with stress. In this research, we examined how different coping strategies (i.e. self-sufficient, social-support, avoidance and religious) predicted the adoption of COVID-19 conspiracy theories. In two studies (Study 1, n = 1000 and Study 2, n = 616) conducted among Polish participants, we found that avoidance and religious coping were positively linked to COVID-19 conspiracy beliefs. In Study 1, conspiracy beliefs also mediated the positive relationships between avoidance and religious coping and adherence to safety and self-isolation guidelines during the COVID-19 pandemic. Study 2 additionally showed that the relationship between fear, induced by reading threatening news on COVID-19, and conspiracy beliefs was the strongest among those high in avoidance coping. These studies highlight the role of coping strategies in the adoption of COVID-19 conspiracy beliefs.

A synthesis of evidence for policy from behavioural science during COVID-19

Scientific evidence regularly guides policy decisions1, with behavioural science increasingly part of this process2. In April 2020, an influential paper3 proposed 19 policy recommendations ('claims') detailing how evidence from behavioural science could contribute to efforts to reduce impacts and end the COVID-19 pandemic. Here we assess 747 pandemic-related research articles that empirically investigated those claims. We report the scale of evidence and whether evidence supports them to indicate applicability for policymaking. Two independent teams, involving 72 reviewers, found evidence for 18 of 19 claims, with both teams finding evidence supporting 16 (89%) of those 18 claims. The strongest evidence supported claims that anticipated culture, polarization and misinformation would be associated with policy effectiveness. Claims suggesting trusted leaders and positive social norms increased adherence to behavioural interventions also had strong empirical support, as did appealing to social consensus or bipartisan agreement. Targeted language in messaging yielded mixed effects and there were no effects for highlighting individual benefits or protecting others. No available evidence existed to assess any distinct differences in effects between using the terms 'physical distancing' and 'social distancing'. Analysis of 463 papers containing data showed generally large samples; 418 involved human participants with a mean of 16,848 (median of 1,699). That statistical power underscored improved suitability of behavioural science research for informing policy decisions. Furthermore, by implementing a standardized approach to evidence selection and synthesis, we amplify broader implications for advancing scientific evidence in policy formulation and prioritization.

Vaccine Hesitancy and Susceptibility to SARS-CoV-2 Misinformation in Japanese Youth: The Contribution of Personality Traits and National Identity

During the pandemic, the Japanese government drew upon the cultural concept of jishuku, or personal self-constraint, requesting that individuals accept responsibility for their behaviors and consider minimizing the potential negative impact on others. While the jishuku approach to pandemic management rests upon the established and persuasive influence of cultural norms, variability in adherence can be expected according to age. This article documents an investigation into factors impacting vaccine hesitancy and susceptibility to SARS-CoV-2 misinformation among Japanese youth. The point of departure is the belief that attitudes and behaviors, such as those underpinning the jishuku approach to pandemic management, arise from within a relational framework. Therefore, developmental characteristics, such as personality traits, and in-group affinity attachments, such as facets of national identity, can be expected to function as predictors of health attitudes and behaviors. The tested structural model of hypothesized interactions accounted for 14% of the observed variance in vaccine hesitancy and 20% in susceptibility to SARS-CoV-2 misinformation. With the inclusion of gender, political ideology, and trust in government SARS-CoV-2 response as control variables, the respecified model increased the amount of variance observed in vaccine hesitancy to 30% and to 25% in susceptibility to SARS-CoV-2 misinformation. The outcomes are discussed in relation to the communication of coherent public health discourse relative to personality traits and facets of national identity.

Shake it off! Adaptive coping with stress reduces national narcissism

Examining the role of coping with stress strategies in shaping national narcissism, we proposed that this type of defensive national commitment (stemming from psychological shortcomings) should be lowered by adaptive coping strategies. In Study 1 (longitudinal, N = 603), we found that higher adaptive (i.e. self-sufficient) coping attenuated national narcissism. In Study 2 (experimental, N = 337), the priming of adaptive coping significantly decreased national narcissism. We also demonstrated the indirect effects of the induced adaptive coping strategy on conspiracy beliefs via national narcissism. These findings suggest that using adaptive coping strategies (either dispositional or situationally induced) may attenuate national narcissism. We discuss the role of coping with stress in shaping group-level phenomena.

The role of early intergroup experiences for identification with all humanity in adulthood

Identification with all humanity (IWAH), defined as a bond with and concern for people all over the world, predicts concern for global problems, commitment to human rights, and prosocial activities. However, it is still unknown how such a broad social identification develops and if early experiences play any role. Two studies explored the role of diverse childhood and adolescence intergroup experiences in predicting IWAH in adulthood. We focused on experiences such as being raised in diversity and having intergroup friends, helping or being helped by various others, and having experiences leading to re- or de-categorization, and introduced a new Childhood/Adolescent Intergroup Experiences (CAIE) scale. Study 1 (N = 313 U.S. students, M age = 21) and Study 2 (N = 1,000, a representative Polish sample, M age = 47) found that this kind of intergroup experiences during childhood and adolescence predicted IWAH beyond the effects of its other known predictors, such as empathy, openness to experience, universalism, right-wing authoritarianism, social dominance orientation or ethnocentrism. These results, obtained on various samples and in countries with different ethno-cultural contexts, point to potential ways of enlarging IWAH during childhood and adolescence.

Implications for COVID-19 vaccine uptake: A systematic review

BACKGROUND

Globally, increasing coronavirus disease (COVID-19) vaccination coverage remains a major public health concern in the face of high rates of COVID-19 hesitancy among the general population. We must understand the impact of the determinants of COVID-19 vaccine uptake when designing national vaccination programmes. We aimed to synthesise nationwide evidence regarding COVID-19 infodemics and the demographic, psychological, and social predictors of COVID-19 vaccination uptake.

METHODS

We systematically searched seven databases between July 2021 and March 2022 to retrieve relevant articles published since COVID-19 was first reported on 31 December 2019 in Wuhan, China. Of the 12,502 peer-reviewed articles retrieved from the databases, 57 met the selection criteria and were included in this systematic review. We explored COVID-19 vaccine uptake determinants before and after the first COVID-19 vaccine roll-out by the Food and Drug Authority (FDA).

RESULTS

Increased COVID-19 vaccine uptake rates were associated with decreased hesitancy. Concerns about COVID-19 vaccine safety, negative side effects, rapid development of the COVID-19 vaccine, and uncertainty about vaccine effectiveness were associated with reluctance to be vaccinated. After the US FDA approval of COVID-19 vaccines, phobia of medical procedures such as vaccine injection and inadequate information about vaccines were the main determinants of COVID-19 vaccine hesitancy.

CONCLUSION

Addressing effectiveness and safety concerns regarding COVID-19 vaccines, as well as providing adequate information about vaccines and the impacts of pandemics, should be considered before implementation of any vaccination programme. Reassuring people about the safety of medical vaccination and using alternative procedures such as needle-free vaccination may help further increase vaccination uptake.

Prosociality and health: Identification with all humanity is a replicable predictor of prosocial motivation for health behaviors

The acute phase of the COVID-19 pandemic may have passed, but the pandemic remains a major worldwide health concern that demands continued vigilance. Are there individual differences that predict the motivation to continue to wear masks and to create physical distance in public? Previous research conducted early in the pandemic had suggested that a particular social identity-identification with all humanity-is one underlying factor that contributes to people's cooperation with health behavior guidelines. This highlights that the pandemic is not only an issue to be tackled with the tools of immunology and epidemiology. It also requires the tools from psychology-to measure the representations people have about themselves and others and how these representations drive values and decisions related to health. Here we report work on U.S. respondents that examined whether individuals' level of identification with all humanity predicts their prosocial health behaviors aimed at mitigating the spread of COVID-19. In 3 convergent studies (total N = 1,580), we find that identification with all humanity predicted the prosocial motivation to wear masks and to engage in physical distancing when in public without a mask. The results were obtained while controlling for a host of covariates, including demographics, educational attainment, and Big Five personality dimensions. We find that some people have a marked drive to care for the health of strangers, which is significantly linked to their concern for all humanity rather than being restricted to their care for their community or country. Discussion focuses on this social identification with humanity and its enduring, replicable role in predicting the motivation to engage in prosocial health behaviors. We note key implications for theories in social and developmental psychology as well as for research that may lead to practical applications for lessening the human toll of the current and future pandemics.

COVID-19, economic threat and identity status: Stability and change in prejudice against Chinese people within the Canadian population

OBJECTIVES

Previous studies found a general increase in prejudice against Chinese people during the first months of the pandemic. The present study aims to consider inter-individual heterogeneity in stability and change regarding prejudice involving Chinese people during the pandemic. The first objective is to identify and describe different trajectories of prejudice over a seven-month period during the pandemic. The second and third objectives are to test the association between trajectory group membership and antecedent variables such as: socio-demographic factors (i.e., age, gender, political affiliation) and two psychological mechanisms, namely economic threat and global citizenship identification.

METHODS

A representative Canadian sample (N = 3,617) according to age, gender and province of residence, was recruited for a 10-wave survey starting from April 2020 to December 2020. First, a group-based modeling approach was used to identify trajectories of prejudice. Second, a multinomial logistic regression model was used to test associations between membership in trajectories and antecedents.

RESULTS

Four trajectories were identified. The first three trajectories have a low (71.4% of the sample), high (18.5%) or very high (5.3%) level of prejudice against Chinese people which is relatively stable over time. The fourth trajectory (4.9%) reports low levels of prejudice in favor of Chinese people which become more positive throughout 2020. Regarding socio-demographic factors: gender is not associated with trajectory group membership, younger people are more likely to follow the trajectory in favor of Chinese people and conservatives are more likely to follow the highest trajectories against Chinese people. Regarding some psychological mechanisms: personal but not collective economic threat is associated with the trajectory in favor of Chinese people. Finally, the highest levels of prejudice are found when the strategy of identification is more local rather than global.

CONCLUSION

The present study shows that Canadians differ in terms of both their level and change in prejudice against Chinese people throughout the pandemic with some socio-demographic groups being more likely than others to be associated with prejudice. The results also suggest that a promising way to tackle the major social issue of prejudice is to highlight a vision of the world where individuals are all "global citizens" facing the same challenge.

The relationship between knowledge about the pandemic and willingness to get vaccinated against SARS-CoV-2 in medical students in Poland: A cross-sectional survey

The COVID-19 pandemic underlines the importance of targeting the groups with the highest risk of vaccine hesitancy, understanding their fears, and alleviating them. As the pandemic situation is very dynamic due to the appearance of new SARS-CoV-2 variants, concerns might also change over time. This is the first study to evaluate the vaccination rate and state of knowledge among medical students in Poland, comparing English and Polish divisions. We collected the data in 2 months. A total of 1,521 surveys were collected as follows: 273 students from the English division and 1,248 students from the Polish division answered the survey. The questionnaire was aimed at investigating students' awareness, knowledge, and apprehensions toward the COVID-19 pandemic and vaccines. The results were obtained for the following statements: good knowledge about ways of transmission is not statistically significant in determining if a student is vaccinated. Moreover, a year of study is not statistically significant in determining if a student knows all ways of COVID-19 transmission. Interestingly, the correlation between the statement "Keeping up to date with the upcoming vaccines is important for my role as a future health care worker" and being vaccinated against SARS-CoV-2 showed that 45.5% of unvaccinated students did not update their information about the vaccines and rated 1 out of 5 for this statement (p < 0.001). Even though the pandemic will not last forever, the obtained knowledge about the role of individual interests can be applied in many different life situations as this feature is statistically significant.

The Identification With All Humanity (IWAH) scale: its psychometric properties and associations with help-seeking during COVID-19

The Identification With All Humanity (IWAH) scale was designed to measure the extent to which an individual identifies oneself with all human beings. The current research aimed to conduct the validation of IWAH in a Chinese population and its convergent validity, as well as test the implications of IWAH in associations with help-seeking behaviour during COVID-19. A serial of three studies was conducted from September 1st 2020 to the end of October 2020. The series of studies included Study 1- Exploring the dimensions of the IWAH scale with a sample of 2,881 participants, Study 2- Confirmatory Factor Analysis for the Chinese IWAH dimensions with a separate sample of 6,667 participants, and Study 3- Role of the IWAH in the COVID-19 pandemic with a sample of 9,046 participants. Study 1 found the Chinese version of the IWAH scale to be a two-dimensional construct, with factor 1 - Bond with Humanity and factor 2 - Human Kinship. Study 2 confirmed the two-factor construct as found in Study 1. It also showed positive relations between IWAH and moral judgement, collectivism, nature connectedness, and negative relations with callousness, and having anxiety and depressive symptoms. Study 3 found that IWAH was negatively related to fear of COVID-19 and positively related to the likeliness of help-seeking. This is the first research to test the factorial structure of the IWAH scale in a Chinese population, with the adaptation showing good psychometric properties. The implication of IWAH on fear of COVID-19 and help-seeking provided further understanding of the possible practical value of IWAH during times of global stressful life events. Furthermore, study 3 is the first to explore how IWAH relates to anxiety, depression, and callousness.

Can science fiction engagement predict identification with all humanity? Testing a moderated mediation model

Identification with all humanity (IWAH) is viewed as a critical construct that facilitates global solidarity. However, its origins have rarely been explored in previous literature, and no study has yet investigated the role of pop-culture in cultivating IWAH. To address this gap, this study initially focuses on science fiction (sci-fi), a specific pop-culture genre with worldwide audiences, and examines its effect on IWAH. It hypothesized a direct association between sci-fi engagement and IWAH from the narrative persuasion approach, and an indirect association via abstract construal based on the cognitive-literary approach. Moreover, the moderating role of actively open-minded thinking (AOT) in the direct and indirect association was also assessed. Results were obtained through a cross-sectional survey conducted in China (n = 570) and showed that sci-fi engagement was positively associated with IWAH; this association was also partially mediated by abstract construal. Interestingly, and inconsistent with our hypotheses, AOT positively moderated the indirect effect but negatively moderated the direct effect. Theoretical and practical implications for cultivating IWAH from the media and pop-cultural perspective were discussed.

The devil is not as black as he is painted? On the positive relationship between food industry conspiracy beliefs and conscious food choices

Previous research found that conspiracy beliefs were usually activated when individuals faced different types of psychological threats and that they led mainly to maladaptive individual and societal outcomes. In this research, we assumed that potential harmfulness of conspiracy beliefs may depend on the context, and we focused on the link between food industry conspiracy beliefs and conscious food choices. We hypothesized that food industry conspiracy beliefs may allow for a constructive attempt to protect oneself against real or imagined enemies (i.e., food industry companies) by conscious food choices (e.g., paying attention to how much the food products are processed). We tested this hypothesis among Polish participants (Study 1; N = 608; cross-sectional and Study 2; N = 790; experimental). Study 1 confirmed that context-specific conspiracy beliefs (but not general notions of conspiracy) are associated with adaptive consumer behaviors. Study 2 showed that inducing feelings of threat related to the possibility of purchasing food contaminated by a harmful bacteria (vs. control condition) increased food industry conspiracy beliefs, which were further positively linked to conscious food choices. We discuss the role of threat and conspiracy beliefs in adaptive consumer behaviors related to food choices.

Perceived parenting and identification with all humanity: Insights from England and Germany

In the past decade, identification with all humanity (IWAH) has been found to predict several positive behavioral outcomes like volunteering, a willingness to contribute to humanitarian relief, and cooperative health behavior during the COVID-19 pandemic. However, to this day, little is known about how individual differences in IWAH emerge. Therefore, the present study aimed to explore whether there is a relationship between individuals’ upbringing and their IWAH. For this purpose, data on IWAH, remembered parenting behavior (RPB), and remembered parental attachment assessed by 3056 individuals (1517 from Germany and 1539 from England) were analyzed. Structural equation models were used to (A) analyze the correlations between RPB, attachment, and IWAH and to (B) test whether single facets of RPB and attachment could significantly predict IWAH when controlling for the other facets in a latent regression analysis. The facets of positive RPB correlated significantly positively with the two facets of IWAH (global self-definition and global self-investment) and explained between 4.1 and 7% of their variance. Surprisingly, in the English sample, two facets of negative RPB also correlated significantly positively with IWAH. The explained variance in IWAH being significant but small, it is argued that parents’ attitudes or behavior specifically related to IWAH could have a greater impact on IWAH than more unspecific parenting behavior. For instance, we discovered that the extent to which participants perceived their parents as global citizens explained about one third of the variance in their own identification as global citizens. Fostering IWAH could constitute an effective approach to tackle important global challenges. Therefore, more research is needed to test the generalizability of the results and to further analyze the roots of people’s IWAH.

Identification with humanity and health-related behaviors during COVID-19

This research takes a maximally inclusive social identity approach to COVID-19 and examines whether the “bond” and “concern” factors of identification with humanity: (1) explain additional variance in health-related behaviors—above and beyond relevant covariates; (2) are uniquely associated with health-related behaviors; and (3) were more strongly associated with health-related behaviors when COVID-19 cases were high. Results ( N = 324) suggest the bond and concern factors explained significantly more variance in social distancing, social influencing, overbuying, and marginally more variance in mask wearing. Bond with all humanity uniquely predicted more mask wearing, more social influencing, less social distancing, and more overbuying, and concern for all humanity uniquely predicted more social distancing and less overbuying. However, COVID-19 cases did not consistently moderate associations with health-related behaviors. Overall, identification with humanity has an important role in—and the bond and concern factors have distinct associations with—health-related behaviors during the COVID-19 pandemic.

Why do narcissists find conspiracy theories so appealing?

Narcissism-a conviction about one's superiority and entitlement to special treatment-is a robust predictor of belief in conspiracy theories. Recent developments in the study of narcissism suggest that it has three components: antagonism, agentic extraversion, and neuroticism. We argue that each of these components of narcissism might predispose people to endorse conspiracy theories due to different psychological processes. Specifically, we discuss the role of paranoia, gullibility, and the needs for dominance, control, and uniqueness. We also review parallel findings for narcissistic beliefs about one's social groups. We consider the wider implications this research might have, especially for political leadership. We conclude by discussing outstanding questions about sharing conspiracy theories and other forms of misinformation.
