During COVID-19, conspiracy theories were intensely discussed in the media. Generally, both believing in conspiracy theories (i.e., explanations for events based on powerholders’ secret arrangements) and being confronted with a conspiracy theory have been found to predict cognition and behavior with negative societal effects, such as low institutional trust. Accordingly, believing in conspiracy theories around COVID-19 should reduce institutional trust, support of governmental regulations and their adoption, and social engagement (e.g., helping members of risk groups). We tested these predictions in a national random sample survey, an experiment, and a longitudinal study ( N total = 1,213; all studies were preregistered). Indeed, believing in and being confronted with a COVID-19 conspiracy theory decreased institutional trust, support of governmental regulations, adoption of physical distancing, and—to some extent—social engagement. Findings underscore the severe societal effects of conspiracy theories in the context of COVID-19.
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 pandemic is to understand the antecedents and consequences of COVID-19 conspiracy beliefs, which are here presented in a rapid review summarizing research from more than 28 countries. We evaluate the contribution of individual difference variables (demographic variables, personality traits, coping with threat and uncertainty), beliefs, biases, and attitudes (epistemically suspect beliefs, thinking styles and cognitive biases, attitudes towards science), and social factors (group identities, trust in authorities, social media) to COVID-19 conspiracy theories. We discuss the consequences of COVID-19 conspiracy beliefs in regard to safeguarding behaviours (hygiene, distancing, and mask-wearing), self-centred (hoarding) and misguided behaviours (pseudoscientific practices), vaccination intentions, mental health and negative social consequences (e.g., discrimination and violence). Differences between countries as well as various conspiracy theories are considered. Summarising, we suggest that belief in COVID-19 conspiracy theories is boosted by low levels of trust in a context of threat and low levels of comprehensive, accessible information in a context of uncertainty and unknowns. We conclude that research is urgently needed to address potential interventions to (re-)establish trust and provide accessible information about COVID-19.
This N = 173,426 social science dataset was collected through the collaborative COVIDiSTRESS Global Survey – an open science effort to improve understanding of the human experiences of the 2020 COVID-19 pandemic between 30th March and 30th May, 2020. The dataset allows a cross-cultural study of psychological and behavioural responses to the Coronavirus pandemic and associated government measures like cancellation of public functions and stay at home orders implemented in many countries. The dataset contains demographic background variables as well as measures of Asian Disease Problem, perceived stress (PSS-10), availability of social provisions (SPS-10), trust in various authorities, trust in governmental measures to contain the virus (OECD trust), personality traits (BFF-15), information behaviours, agreement with the level of government intervention, and compliance with preventive measures, along with a rich pool of exploratory variables and written experiences. A global consortium from 39 countries and regions worked together to build and translate a survey with variables of shared interests, and recruited participants in 47 languages and dialects. Raw plus cleaned data and dynamic visualizations are available.
Conspiracy theories offer unvalidated explanations for important political and societal events and thus are likely to develop around a crisis, such as the Corona pandemic. Research has shown that a general tendency to believe in conspiracy theories—a so-called conspiracy mentality—comes with negative societal consequences, such as decreased social engagement and less trust in authorities. However, this has not been tested for concrete conspiracy theories like the ones around the Corona pandemic. Social engagement and trust in authorities are essential to successfully fight the pandemic. Therefore, we examined the relation between the belief in two Corona-related conspiracy theories and trust in authorities, support for governmental regulations, social engagement, social distancing, and hygiene measures in two studies (total N = 909). Believing in a Political Corona Conspiracy (accusing government and media) showed a stronger (and unique) negative relation to all desired outcomes than believing in a China Corona Conspiracy (accusing China of developing the virus). However, believing in the theories was not related to hygiene measures. Overall, believing in specific conspiracy theories predicts harmful attitudes and behaviours similarly to conspiracy mentality, but to a stronger extent. Findings underscore the relevance of conspiracy theories in the context of the Corona pandemic.
