Number of research on conspiracy theories is continuously growing. Conspiracy theories are explained through roles of cognitive biases, belief systems, motives, and individual differences. New research emphasizes role of context in formation of belief in conspiracy theories. Aim of this study was to examine the effects guilt attribution regarding ideological orientation, closeness of the events, and feedback has on belief in conspiracy theories. 226 individuals participated in this study. The measure of belief in conspiracy theories is “conspiratorial vignette”, which was created for the purposes of this research and covers an event that did not occur. This way problems that are often faced when researching belief in conspiracy theories considering popularity and knowledge of specific conspiracies are avoided. As a measure of ideological orientation Questionnaire of general ideological orientation was used. Closeness was defined through regional affiliation of an individual (categories: close and far). Statistical analysis shows that there are no significant differences in belief in conspiracy theories depending on closeness of events. Generally, subjects with “left” orientation show higher belief in conspiracy theories compered to subject with “right” orientation; and belief in conspiracy theories was higher when object of the guilt attribution is corporation compered to minister in the government. Interaction was not significant in examining effects of ideological orientation and guilt attribution on belief in conspiracy theories. When examining effect of feedback on belief in conspiracy theories, interaction was statistically significant. In the second measuring, confirmatory feedback led to higher belief in conspiracy theories compered to dismissive feedback, while there were no differences in first measuring point. Participants showed higher belief in conspiracy theories in second point of measure compared to first when exposed to confirmatory feedback. Participants showed higher belief in conspiracy theories in first point of measure compared to second when exposed to dismissive feedback. Scientific consensus regarding the factors that lead to belief in conspiracy theories is yet to be established which is way further research is needed.
