Promoting Tolerance Through Learning About Human Evolution And Creation Myths, Afsoon Alishahi

Doctoral Dissertations

The role that religion plays in the lives of humans is complex, contradictory, and deeply impactful. According to Allport (1979), religion has a paradoxical function in that it can either combat or contribute to prejudice. A meta-analysis by Hall, Matz, and Wood (2010) found a significant correlation between being deeply religious and having racial prejudice. Similarly, many social scientific studies since 1940 have concluded that religious individuals are more prejudiced than less religious individuals (Hunsberger & Jackson, 2005).

Therefore, the purpose of this study was to examine whether gaining knowledge about human evolution, creation myths, and their relationship to religious …
