Abstract
Multicultural research has shown that rates of psychopathy differ between North America and Europe. Many suggestions have been given to help explain this divergence, including: cultural factors, migration, and inter-rater effects. However, past research has not explored the possibility that samples may be inherently different independent of a cultural factor. This paper explores the prospect of multicultural samples differing due to effects of the legal system. Research suggests that incarceration policies may affect the percentage of psychopaths in the prison systems, where the majority of psychopathy research takes place. Future research and policy implications are discussed to further explore this possibility.
