The targets of all treachery: Delusional ideation, paranoia, and the need for uniqueness as mediators between two forms of narcissism and conspiracy beliefs

Validating the IDRIS and IDRIA: Two infrequency/frequency scales for detecting careless and insufficient effort survey responders

To detect careless and insufficient effort (C/IE) survey responders, researchers can use infrequency items - items that almost no one agrees with (e.g., "When a friend greets me, I generally try to say nothing back") - and frequency items - items that almost everyone agrees with (e.g., "I try to listen when someone I care about is telling me something"). Here, we provide initial validation for two sets of these items: the 14-item Invalid Responding Inventory for Statements (IDRIS) and the 6-item Invalid Responding Inventory for Adjectives (IDRIA). Across six studies (N1 = 536; N2 = 701; N3 = 500; N4 = 499; N5 = 629, N6 = 562), we found consistent evidence that the IDRIS is capable of detecting C/IE responding among statement-based scales (e.g., the HEXACO-PI-R) and the IDRIA is capable of detecting C/IE responding among both adjective-based scales (e.g., the Lex-20) and adjective-derived scales (e.g., the BFI-2). These findings were robust across different analytic approaches (e.g., Pearson correlations; Spearman rank-order correlations), different indices of C/IE responding (e.g., person-total correlations; semantic synonyms; horizontal cursor variability), and different sample types (e.g., US undergraduate students; Nigerian survey panel participants). Taken together, these results provide promising evidence for the utility of the IDRIS and IDRIA in detecting C/IE responding.

Dark Triad personality traits and realistic and symbolic COVID-19 threat: The role of conspiracy mentality

The COVID-19 pandemic has profoundly altered global social dynamics through extensive containment measures. Understanding how individuals perceive the virus, distinguishing between realistic and symbolic threats, and considering the influence of personality traits is essential for effective public health messaging and interventions. This study explores the linkage between personality traits and perceived COVID-19 threats, mediated by conspiracy mentality, across diverse international contexts. Online survey data were collected in June 2021 from 13,645 participants across seven European countries, the US, and Colombia. The study explores how individuals with different Dark Triad traits perceive the threat of COVID-19, and whether conspiracy mentality mediates these perceptions. The findings reveal distinct associations. Machiavellianism and narcissism were linked to lower perceived COVID-19 threat, while psychopathy was associated with greater perceived threat. Additionally, individuals with higher conspiracy mentality endorsed greater perceived threat related to COVID-19. This study highlights the influence of Dark Triad personality traits on how individuals perceive the threats posed by COVID-19, with conspiracy mentality mediating this relationship. Understanding these associations provides valuable insights into psychological factors affecting COVID-19 perception, informing future research and public health strategies.

Narcissistic susceptibility to conspiracy beliefs exaggerated by education, reduced by cognitive reflection

Conspiracy theories are alternate viewpoints of provided explanations; sensational stories revolving around small groups exerting control for nefarious reasons. Recent events and research have outlined myriad negative social and personal outcomes for those who endorse them. Prior research suggests several predictors of susceptibility to conspiracy theories, including narcissistic personality traits (grandiosity, need for uniqueness), cognitive processes (critical thinking, confirmation bias) and lack of education. The aim of the current paper was to explore how facets of narcissism predict susceptibility to conspiracy theories. It was expected that narcissism would be a positive predictor, but education and cognitive reflection would act as protective factors, reducing this effect. Study one utilized an international survey (N = 323) to investigate the role of education as a protective tool in the relationship between narcissistic traits and conspiratorial beliefs. Support was found for the hypotheses that individuals with higher levels of grandiosity, vulnerable narcissism, a strive for uniqueness, and a strive for supremacy predicted higher levels of conspiracy endorsement. Higher education and STEM education were associated with lower levels of conspiracy endorsement, however all significant moderations indicated that for narcissistic individuals, education increased their likelihood of adopting conspiracy beliefs, contrary to expectation. To investigate this further, study two analyzed a large-scale publicly available dataset (N = 51,404) to assess the relationship between narcissism, critical thinking skills (specifically cognitive reflection) and conspiracy beliefs pertaining to the COVID-19 pandemic. As expected, analysis found narcissism and poor cognitive reflection (intuitive thinking) as predictors of conspiracy beliefs. Higher levels of cognitive reflection were found to be protective, moderating and reducing the impact of narcissism on endorsement of conspiracy theories. The findings suggest that cognitive reflection, but not education protect against narcissistic conspiracy belief. Moreover, that cognitive reflection may have a lessened effect against conspiracy theories adopted for social or ideological reasons. These findings improve understanding of both the role and limitations of education/critical thinking skills as protective factors against conspiracy theory endorsement.

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.

An interpretation of meta-analytical evidence for the link between collective narcissism and conspiracy theories

Meta-analytical evidence indicates the robust association between collective narcissism and conspiracy theories is moderated by the content of conspiracy theories. Belief in conspiracies of specific outgroups fits collective narcissistic posture of intergroup hostility but collective narcissism is also bound to other conspiracy theories because it simultaneously comprises a committed belief (that the ingroup is great) and a threatening belief (that the ingroup is unrecognized). This creates compensatory motivations to believe in conspiracy theories that protect the committed belief and to seize on any conspiracy theory as a meaning-making activity. Collective narcissism and conspiracy theories may also co-occur because they serve to coordinate undemocratic leaders and their constituencies. They produce threatening environments that justify coercion, violence and undemocratic governance.

Antecedents and consequences of COVID-19 conspiracy beliefs: A systematic review

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 conspiracy beliefs and to synthesise this research to make it widely accessible.

METHODS

We present a synthesis of COVID-19 conspiracy belief research from 85 international articles, identified and appraised through a systematic review, in line with contemporary protocols and guidelines for systematic reviews.

RESULTS

We identify a number of potential antecedents of COVID-19 conspiracy beliefs (individual differences, personality traits, demographic variables, attitudes, thinking styles and biases, group identity, trust in authorities, and social media use), their consequences (protective behaviours, self-centred and misguided behaviours such as hoarding and pseudoscientific health practices, vaccination intentions, psychological wellbeing, and other negative social consequences such as discrimination and violence), and the effect sizes of their relations with the conspiracy beliefs.

CONCLUSIONS

We conclude that understanding both the potential antecedents and consequences of conspiracy beliefs and how they are context-dependent is highly important to tackle them, whether in the COVID-19 pandemic or future threats, such as that of climate change.
