Extensive research conducted across 30 countries revealed that persecutory delusions were the most common, followed by reference, grandiose, control, and religious delusions. These findings remained consistent across multiple studies, regardless of the number of delusional themes examined or if a single theme was focused on. The prevalence of delusions was unaffected by study quality, publication date, country development, or individualism. Interestingly, higher income inequality in countries correlated with higher rates of religious and control delusions. These delusional themes are believed to reflect universal human challenges and existential dilemmas.
