The main aim of the study is to test whether Narcissism, found to be reliably related to conspiracy, contributes to the explanation of the beliefs in conspiracy theories above the seven basic personality traits, defined by HEXACO and Disintegration trait. We will test the cross-cultural invariance of the relations in two different cultural groups: UK and Germans. The first hypothesis is that the Disintegration explains variance in the beliefs in conspiracy theories incrementally to the HEXACO traits. Second, we expect that Narcissism does not explain variance in the beliefs in conspiracy theories incrementally to the HEXACO traits complemented with Disintegration. Third, the structural model of narcissism, HEXACO, and disintegration in conspiracy beliefs is expected to reveal the crucial role of Disintegration, Honesty (or Agreeableness) and Conscientiousness in the conspiracy beliefs, while Narcissism is expected to have at best partial mediatory role between these personality traits and conspiracy beliefs. The model is expected to be invariant across the two samples. Data will be collected using a 100-item HEXACO personality inventory assessing six basic personality traits, and the 20-item DELTA questionnaire measuring Disintegration trait. Conspiracy beliefs will be measured using the15-item Generic Conspiracist Beliefs Scale, while Narcissism will be assessed using the 18-item version of the Individual narcissism scale. In addition, sociodemographic data on gender, age and educational level will be collected. For data analyses, we will employ Hierarchical regression analysis and Multi-group Structure Equation Modeling (SEM).
