Previous literature on conspiracy beliefs has an important gap, as it has almost completely excluded conspiracy beliefs relating to LGBTQ+ people. The purpose of the present research was to develop and validate a specific tool to measure the Gender Ideology and LGBTQ+ Lobby Conspiracies Beliefs: the GILC scale. Two independent data collections ( N _tot = 1.908) were run involving both heterosexual and gay, lesbian and bisexual people. We expected a mono‐factorial structure of the tool, with high levels of internal reliability, invariant by respondents' gender, sexual orientation and previous knowledge or hearsay of gender ideology. Furthermore, we expected that GILC scale manages to measure a differentiated construct: (a) compared to other specific and general conspiracy contents; (b) compared to a generic disposition to engage in conspiratorial mentality; (c) compared to existing measures of sexual prejudice, stereotypes and negative attitudes towards sexual minority people. In relation to criterion validity, we expected that several psychosocial and socio‐political ideology variables (i.e. RWA and SDO), would associate with high levels in GILC scale. The results confirmed our expectations, showing that GILC scale is a short tool which include nine items with a mono‐factorial structure and with excellent psychometric properties. Limitations and further research directions are discussed.

The overarching aim of the present research is to investigate whether and how HEXACO personality traits relate to climate change action, pro‐environmental behavior, and moral anger. A sample of 268 community participants provided responses for measures of the HEXACO model, moral anger, intention to engage in climate change action, and pro‐environmental behavior. Hierarchical tests indicated that (1) Openness to Experience outperformed the other HEXACO personality traits in predicting climate change action, whereas (2) both Openness to Experience and Honesty–Humility outperformed the other HEXACO personality traits in predicting pro‐environmental behavior, controlling for participants’ gender, age, education, and employment status. Specifically, mediation analyses showed that (3) Openness to Experience was related to climate change action both directly and indirectly via moral anger. Furthermore, (4) Openness to Experience and Honesty–Humility were independently related to pro‐environmental behavior both directly and indirectly via moral anger.

The ascent of populism has been linked with economic and cultural disruptions of modernization. From this perspective, it could be implied that factors such as psychological insecurity and uncertainty are key in making voters gravitate toward the populist narrative. The present research aimed at highlighting the psychological determinants that uncertainties deriving from modernization processes may activate in populist voters. Specifically, we focused on immigration in Italy, investigating whether and how support for different populist parties relates to development of negative attitudes toward immigrants. Two samples of Italian adults (total N = 1655), who voted in the Italian general elections of March 4, 2018 took part in the research. Multigroup path analysis showed that assumption of anti‐immigration stances through the joint mediating role of Dangerous World Belief and Right‐Wing Authoritarianism was shared by different groups of populist voters. However, different populist voters differed in the strength of the path passing through Competitive Jungle World Belief and Social Dominance Orientation. Results underline the relevance of social worldviews and ideological attitudes in shaping the attitudes of the Italian populist electorate.
