Introduction
I am currently preoccupied with irrational/epistemologically suspect beliefs, especially in the domain of health, and their relation to questionable health practices that can be deceptive or downright dangerous.

Direct contact between members of ethnic groups is proven to reduce intergroup prejudice. Recent research, however, explores the effects of alternative types of contact, amongst them via social networks in virtual space. This is especially important for e.g. post-conflict societies in which there is limited opportunity for direct contact between th...
This is the accepted version of the article: Lazić, A., & Žeželj, I. (2021). A systematic review of narrative interventions: Lessons for countering anti-vaccination conspiracy theories and misinformation. Public Understanding of Science. https://doi.org/10.1177/09636625211011881
Even if a small portion of the population refuses vaccination due to a...
Amidst the flow of conspiracy theories (CTs) about the COVID-19 pandemic, many were logically incompatible. We aimed to map the psychological profile of their endorsers. Upon pretesting for familiarity and logical incompatibility, we choose eight pairs of contradictory COVID-19 CTs. Across three studies, a substantial portion of respondents (40%–42...
Health care policies often rely on public cooperation, especially during a health crisis. However, a crisis is also a period of uncertainty and proliferation of health-related advice: while some people adhere to the official recommendations, others tend to avoid them and resort to non-evidence based, pseudoscientific practices. People prone to the...
People resort to various questionable health practices to preserve or regain health - they intentionally do not adhere to medical recommendations (e.g., self-medicate or modify the prescribed therapies;iNAR), or use traditional/complementary/alternative (TCAM) medicine. As retrospective reports overestimate adherence and suffer from recall and desi...
A growing body of evidence suggests that questionable health behaviors- not following medical recommendations and resorting to non-evidence based treatments—are more frequent than previously thought, and that they seem to have strong psychological roots. We thus aimed to: 1) document the lifetime prevalence of intentional non-adherence to medical r...
When a multiethnic state, such as the former Yugoslavia, dissolves in a violent ethnic‐based conflict, new generations grow up on one‐sided historical narratives. While there is plenty of evidence of how appropriating such narratives delegitimises outgroups, studies on how young people coordinate diverse group narratives are lacking. To address thi...
Despite assumptions that people strive for consistency between their beliefs, endorsement of mutually incompatible ones is not rare - a tendency we have previously labelled doublethink, by borrowing from Orwell. In an attempt to understand the nature of doublethink and the underlying mechanism that enables incompatible beliefs to coexist, we conduc...
The proportion of the population who are vaccinated against an infectious disease is significant – not only because vaccination keeps the virus from spreading, but also because learning about how many members of one’s community have decided to get vaccinated has been shown to affect individual vaccination intention. In three preregistered online ex...
Background: Traditional, complementary and alternative medicine (TCAM) encompasses a wide range of healthcare practices that are typically not part of “conventional” medicine and that are widely used in general populations. The aim of the study was to test for the most appropriate latent structure of a comprehensive instrument measuring TCAM use an...
While irrational beliefs cluster together, their content differs widely, from beliefs about collective memories shaping biological properties (pseudoscientific) to those about premonition (extrasensory). This difference might extend further - they might reflect similar thinking dispositions, but be differently embedded in worldviews (pseudoscientif...
The onset of the COVID-19 pandemic saw a shift toward a more traditional division of labor–one where women took greater responsibility for household tasks and childcare than men. We tested whether this regressive shift was more acutely perceived and experienced by women in countries with greater gender equality. Cross-cultural longitudinal survey d...
Despite assumptions that people strive for consistency between their beliefs, endorsement of mutually incompatible ones (so-called doublethink) is not rare. In an attempt to understand the nature of doublethink and the underlying mechanism that enables incompatible beliefs to coexist, we conducted two preregistered studies (total N=691). While doub...
Irrational beliefs encompass a broad set of beliefs that lack verifiable empirical evidence and contradict scientific principles, often grouped into conspiratorial, pseudoscientific, and paranormal domains. This paper investigated whether these beliefs are rooted in a set of cognitive biases. Across four studies, low socioeconomic status, right-win...
Background: In the REASON4HEALTH project, we explored the structure, prevalence, and psychological factors predicting intentional non-adherence to official medical recommendations (iNAR) and the use of traditional, complementary, and alternative medicine (TCAM) in Serbia. Methods: Focus groups with clinicians and TCAM practitioners and a literature...
Scientism proposes science to be an all-powerful human enterprise, able to answer not only all practical but also philosophical or moral questions. We are taking a psychological approach to scientism, studying uncritical trust in science and uncritical trust in scientists as a part of a unique attitudinal tendency. Our novel measure assesses both k...
Virus mitigation behavior has been and still is a powerful means to fight the COVID-19 pandemic irrespective of the availability of pharmaceutical means (e.g., vaccines). We drew on health behavior theories to predict health-protective (coping-specific) responses and hope (coping non-specific response) from health-related cognitions (vulnerability,...
Introduction
We will launch a national survey in Serbia to document the prevalence of two types of questionable health behaviours: (1) intentional non-adherence to medical recommendations and (2) use of traditional, complementary and alternative medicine practices, as well as the relation between the two. We will also investigate their psychologica...

To describe how Serbian online media cover the topic of traditional, complementary, and alternative medicine (TM/CAM), we conducted a content analysis of 182 articles from six news and six magazine websites, published July–December 2021. Biologically based treatments, predominantly herbal products framed as Serbian or Russian folk medicine, were th...
Psychologicalresearchonthepredictorsofconspiracytheorizing—explainingimpor-tant social and political events or circumstances as secret plots by malevolentgroups—has flourished in recent years. However, research has typically examinedonly a small number of predictors in one, or a small number of, national con-texts. Such approaches make it difficult...
Objectives
We aimed to (1) develop a novel instrument, suitable for the general population, capturing intentional non-adherence (iNAR), consisting of non-adherence to prescribed therapy, self-medication and avoidance of seeking medical treatment; (2) differentiate it from other forms of non-adherence, for example, smoking; and (3) relate iNAR to pa...

Socially desirable responding (SDR) is usually treated as a “noise” in psychological research, to be controlled for by creating certain conditions for respondents. We tested a range of cues aimed to decrease/ increase SDR to be applied/avoided in selection or recruitment. To decrease it, we developed two novel procedures: one inspired by the bogus...
Although misinformation is not a new problem, questions about its prevalence, its public impact, and how to combat it have taken on new urgency. An obvious solution to the problem of misinformation is to offer corrections (or debunkings) designed to clarify what is true and what is false. But corrections are not a panacea. Given the scope of the mi...
Some public officials have expressed concern that policies mandating collective public health behaviors (e.g., national/regional “lockdown”) may result in behavioral fatigue that ultimately renders such policies ineffective. Boredom, specifically, has been singled out as one potential risk factor for noncompliance. We examined whether there was emp...
Ova monografija je osmišljena kao klasični deskriptivni pregled rezultata istraživanja društvenih i političkih stavova mladih. Trudili smo se da ove rezultate provučemo kroz prizmu najaktuelnijih teorijskih, metodoloških i empirijskih saznanja iz oblasti istraživanja socijalnih identiteta i društveno-političkih stavova, kako uopšte tako i u lokalno...
Despite global commitments and efforts, a gender‐based division of paid and unpaid work persists. To identify how psychological factors, national policies, and the broader sociocultural context contribute to this inequality, we assessed parental‐leave intentions in young adults (18–30 years old) planning to have children (N = 13,942; 8,880 identifi...
Despite insufficient evidence base for some of its practices, traditional, complementary, and alternative medicine (TCAM) use is rapidly growing; psychological roots of this trend are still under-studied. Based on previous research, input from TCAM practitioners, and content analysis of online media, we developed a comprehensive instrument to measu...
Paralele između pristrasnosti u autobiografskim i kolektivnim sećanjima.
Positivity biases in autobiographical and collective memories.
Background: The World Health Organization recognizes non-adherence to treatment recommendations as a growing global problem. Questionnaires typically focus on only one non-adhering behavior, e.g., medication-taking, and target people with specific health conditions. In this preregistered study, we aimed to (1) develop a novel instrument suitable to...

The aim of the study is to provide a particular portrayal of emergency remote education (ERE) in Serbia from the perspective of its most disadvantaged partakers. The study applied a single-case study design. The participant was an 11-year-old Roma boy, attending the 5th grade of elementary school in Belgrade. Since October 2019, a group of universi...
Objective:
This content analysis study explored how online news media communicates and frames vaccination rates and herd immunity (the effect where enough people are immune, the virus is contained).
Methods:
We analyzed 160 vaccination-related news stories by nine highest-trafficked news websites in Serbia, published July-December 2017, around t...
Differences in attitudes on social issues such as abortion, immigration and sex are hugely divisive, and understanding their origins is among the most important tasks facing human behavioural sciences. Despite the clear psychological importance of parenthood and the motivation to provide care for children, researchers have only recently begun inves...
Group membership is known to influence empathy – people empathise less, fail to empathise, or even take pleasure in outgroup suffering. One promising way to encourage empathy for outgroups involves portraying intergroup empathy as normative. However, people are often unaware of operative empathic norms, and must consequently rely on their subjectiv...

The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...
Anxiety associated with the COVID-19 pandemic and home confinement has been associated with adverse health behaviors, such as unhealthy eating, smoking, and drinking. However, most studies have been limited by regional sampling, which precludes the examination of behavioral consequences associated with the pandemic at a global level. Further, few s...
Previous work has reported a relation between pathogen-avoidance motivations and prejudice toward various social groups, including gay men and lesbian women. It is currently unknown whether this association is present across cultures, or specific to North America. Analyses of survey data from adult heterosexuals ( N = 11,200) from 31 countries show...
Resorting to complementary/alternative medical (CAM) therapies can lead to bad health outcomes or interfere with officially recommended therapies. CAM use is, nevertheless, widespread and growing. This could be partially due to the perception of the CAM industry as powerless and non-profit oriented, in contrast to the pharmaceutical industry (“Big...
The present paper examines longitudinally how subjective perceptions about COVID-19, one’s community, and the government predict adherence to public health measures to reduce the spread of the virus. Using an international survey ( N = 3040), we test how infection risk perception, trust in the governmental response and communications about COVID-19...
People differ in their general tendency to endorse conspiracy theories (that is, conspiracy mentality). Previous research yielded inconsistent findings on the relationship between conspiracy mentality and political orientation, showing a greater conspiracy mentality either among the political right (a linear relation) or amongst both the left and r...
Before vaccines for COVID-19 became available, a set of infection prevention behaviors constituted the primary means to mitigate the virus spread. Our study aimed to identify important predictors of this set of behaviors. Whereas social and health psychological theories suggest a limited set of predictors, machine learning analyses can identify cor...

Rationale
Belief in COVID-19 conspiracy theories can have severe consequences; it is therefore crucial to understand this phenomenon, in its similarities with general conspiracy belief, but also in how it is context-dependent.
Objective
The aim of this systematic review is to provide a comprehensive overview of the available research on COVID-19 c...
Understanding the determinants of COVID-19 vaccine uptake is important to inform policy decisions and plan vaccination campaigns. The aims of this research were to: (1) explore the individual- and country-level determinants of intentions to be vaccinated against SARS-CoV-2, and (2) examine worldwide variation in vaccination intentions. This cross-s...

People prone to the...
In territorial interethnic conflicts people often claim exclusive land ownership for their ingroup. However, they can also view the ingroup and outgroup as entitled to the land. It is unknown what explains such shared ownership perceptions and how these in turn inform opinions about conflict resolution. We focused on different types of collective v...
Tightening social norms is thought to be adaptive for dealing with collective threat yet it may have negative consequences for increasing prejudice. The present research investigated the role of desire for cultural tightness, triggered by the COVID-19 pandemic, in increasing negative attitudes towards immigrants. We used participant-level data from...

This could be partially due to the perception of the CAM industry as powerless and non-profit oriented, in contrast to the pharmaceutical industry (“Big...
During the initial phase of the COVID-19 pandemic, U.S. conservative politicians and the media downplayed the risk of both contracting COVID-19 and the effectiveness of recommended health behaviors. Health behavior theories suggest perceived vulnerability to a health threat and perceived effectiveness of recommended health-protective behaviors dete...
The news media can influence how the public and policymakers feel about vaccination. Perhaps under the impression that such messages can be fear-inducing and thus mobilizing, the media often laments low immunization rates. This could, however, activate a powerful descriptive social norm (“many people are not getting vaccinated”) and may be especial...
Territorial ownership claims are central to many interethnic conflicts and can constitute an obstacle to conflict resolution and reconciliation. However, people in conflict areas might also have a perception that the territory simultaneously belongs to one’s ingroup and the rival outgroup. We expected such perceptions of shared ownership to be rela...
People tend to simultaneously accept mutually exclusive beliefs. If they are generally prone to tolerate inconsistencies, irrespective of their content, we say they are prone to doublethink. We developed a measure to capture individual differences in this tendency and demonstrated its construct and predictive validity across two studies. In Study 1...
What role does intergroup contact play in promoting support for social change toward greater social equality? Drawing on the needs-based model of reconciliation, we theorized that when inequality between groups is perceived as illegitimate, disadvantaged group members will experience a need for empowerment and advantaged group members a need for ac...
Even if a small portion of the population refuses vaccination due to anti-vaccination conspiracy theories or misinformation, this poses a threat to public health. We argue that addressing conspiracy theories with only corrective information is not enough. Instead, considering that they are complex narratives embedded in personal and cultural worldv...
Belief in COVID-19 conspiracy theories can have severe consequences; it is therefore crucial to understand this phenomenon. We present a narrative synthesis of COVID-19 conspiracy belief research from 85 international articles, identified and appraised through a systematic review. We identify a number of significant antecedents of COVID-19 conspira...
In this study, we further explored the validity of a novel psychological construct-Ethnic identity delegitimization (EIDL), a general tendency to question the legitimacy of ethnic groups that have been existing shorter than one's ethnic ingroup. Since it is based on historicity (i.e., the length of a group's existence), we tested its discriminative...
This paper examines whether compliance with COVID-19 mitigation measures is motivated by
wanting to save lives or save the economy (or both), and which implications this carries to fight the
pandemic. National representative samples were collected from 24 countries (N = 25,435). The main
predictors were (1) perceived risk to contract coronavirus, (...
Introducing a concept of perceived dual identity integration (PDII), we test whether, for biculturals to act as agateway group (GG), their identities should be viewed as blended/harmonized by the majority. We provide correlational evidence that PDII underlies the relation between perception of GG (people of Serb-Bosniak origin) as dually identified...
In two post-conflict societies (Serbia and Cyprus), the authors investigated how people cope with in-group historical transgression when heroes and villains relevant for their collective identity are made salient in it. The authors set the events in foundational periods for Serbian (Experiment 1) and Greek Cypriot (Experiment 2) ethnic identity-tha...
Sense of shared group membership can be a powerful socio-psychological tool in mobilising large numbers of people and buffering against uncertainty during a societal crisis. We investigated if ethnic identity can prove as such a resource in preserving emotional well-being and building solidarity to tackle the COVID-19 pandemic. Using correlational...
Amidst the flow of conspiracy theories (CTs) about the coronavirus pandemic, many logically incompatible ones arise. Upon pretesting for familiarity and logical incompatibility, we choose eight pairs of contradictory CTs. Across two studies, we observed a significant portion of respondents (40%-48%) endorsed at least one pair. In Study 1 (N = 290),...
Conspiracy mentality is a general tendency to attribute significant events to the actions of malevolent actors, without referencing to a specific event. In two independent representative surveys of adult Serbian citizens (N1 = 1194; N2 = 1258) we validated Serbian version of the conspiracy mentality questionnaire (CMQ), a reasonably content-free to...
In the coronavirus "infodemic", people are exposed to official recommendations but also to potentially dangerous pseudoscientific advice claimed to protect against COVID-19. We examined whether irrational beliefs predict adherence to COVID-19 guidelines as well as susceptibility to such misinformation. Irrational beliefs were indexed by belief in C...
Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g. religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research,...
COVID-19 conspiracy theories emerged almost immediately after the beginning of the pandemic, and the number of believers does not appear to decline. Believing in these theories can negatively affect adherence to safety guidelines and vaccination intentions, potentially endangering the lives of many. Thus, one part in successfully fighting the pande...
The Coronavirus is highly infectious and potentially deadly. In the absence of a cure or a vaccine, the infection prevention behaviors recommended by the World Health Organization constitute the only measure that is presently available to combat the pandemic. The unprecedented impact of this pandemic calls for swift identification of factors most i...
In this work, we study how social contacts and feelings of solidarity shape experiences of loneliness during the COVID-19 lockdown in early 2020. We draw on cross-national data, collected across four time points between mid-March until early May 2020. We situate our work within the public debate on these issues and discuss to what extent the public...
Although several scholars acknowledge the existence of tears of joy, there is little systematic theoretical or empirical evidence on how positive tears are experienced, what elicits them, what actions or impulses they motivate in the crier, how they differ from tears of sadness or distress and whether there are different types. We systematically in...
According to health behavior theories, perceived vulnerability to a health threat and perceived effectiveness of recommended health-protective behaviors determine motivation to follow these recommendations. Because the U.S. President Trump and U.S. conservative politicians downplayed the risk and seriousness of contracting COVID-19 and the effectiv...
The PsyCorona collaboration is a research project to examine processes involved in the COVID-19 pandemic, such as behavior that curbs virus transmission, which may
implicate social norms, cooperation, and self-regulation. The study also examines psychosocial consequences of physical distancing strategies and societal lockdown, such
as frustration o...
