  • How Does Increased Worry Affect Worries About Unrelated Issues?

    Open AccessJ Urban, Tomasz Grzyb et al.ARTICLECollabra2026

    There are two competing accounts explaining how increased worry about one issue affects people’s worry about unrelated issues. According to one account, it decreases worries about other issues, reflecting a negative cross-effect consistent with the finite pool of worry hypothesis. In the second account, it increases worry, reflecting a positive cross-effect driven by generalized affect and availability heuristics. We conducted a web-based experim…

  • Source awareness and vaccine attitudes

    Open AccessAnna Rędzio, Kamil Izydorczak et al.ARTICLECurrent Psychology2025

    Previous studies on combating disinformation have focused on methods based on rational argumentation like correcting misinformation or on news and media and literacy. However, these methods have proved to be less effective when strong emotions are involved. The presented research tested the effectiveness of a new technique for combating anti-vaccine disinformation: making people aware that most anti-vaccine disinformation comes from a source that…

  • It Matters to Whom You Compare Yourself

    Open AccessWojciech Kulesza, Dariusz Doliński et al.ARTICLEAmerican Journal of Men s Health2023

    Unrealistic Optimism (UO) appears when comparing participants’ risk estimates for themselves with an average peer, which typically results in lower risk estimates for the self. This article reports nuanced effects when comparison varies in terms of the gender of the peer. In three studies (total N = 2,468, representative sample), we assessed people’s risk estimates for COVID-19 infections for peers with the same or other gender. If a peer’s gende…

  • Is the Covid-19 Fake News game good news? Testing whether creating and disseminating fake news about vaccines in a computer game reduces people's belief in anti-vaccine arguments

    Open AccessAnna Magdalena Rędzio, Kamil Izydorczak et al.ARTICLEActa Psychologica2023

    Improving vaccination eagerness is crucial, especially during the ongoing COVID-19 pandemic and establishing new procedures to achieve that goal is highly important. Previous research (Roozenbeek & van der Linden, 2019a, 2019b) has indicated that playing the "Bad News" game, in which a player spreads fake news to gain followers, reduces people's belief in fake news. The goal of the present paper was to test an analogous new game called "COVID-19 …

  • Exposing People to Others Not Following Recommendations Reduces Unrealistic Optimism. An Experiment During a Pandemic

    Open AccessWojciech Kulesza, Dariusz Doliński et al.ARTICLEPolish Psychological Bulletin2023

    Forty years of research on Unrealistic Optimism - a delusion that negative events are less likely and positive events are more likely to happen to oneself (in comparison to others) - has proved to be robust. Importantly, as a result, people holding this bias reduce their engagement in health prevention and following medical recommendations, etc., leading to the conclusion that this bias is dangerous. However, there is hardly any research on how t…

  • Biased Social Comparison in the Moment of Crisis

    Open AccessWojciech Kulesza, Dariusz Doliński et al.ARTICLESocial Psychology2023Cited by: 1References: 39

    The better-than-average effect (BTAE) is a mechanism where people perceive oneself as better than others. The BTAE could be one of the phenomena explaining why people follow - in the moment of a global health crisis - guidelines ("I am superior to others, and I [will]) take extra precautions, e.g., a vaccine shot"). In this paper, we investigate the BTAE with 3,066 respondents. In Study 1, in all countries, across two measurements in time, the BT…
