    Do Political Attitudes and Religiosity Share a Genetic Path?
    (Springer, 2014-10) Friesen, Amanda; Ksiazkiewicz, Aleksander
    Social scientists have long recognized and sought to explain a connection between religious and political beliefs. Our research challenges the prevalent view that religion and politics constitute separate but related belief sets with a conceptual model that suggests the correlation between the two may be partially explained by an underlying psychological construct reflecting first principle beliefs on social organization. Moreover, we also push this challenge further by considering whether part of the relationship between political and religious beliefs is the result of shared genetic influences, which would suggest that a shared biological predisposition, or set of biological predispositions, underlies these attitudes. Using a classic twin design on a sample of American adults, we demonstrate that certain religious, political, and first principle beliefs can be explained by genetic and unique environmental components, and that the correlation between these three trait structures is primarily due to a common genetic path. As predicted, this relationship is found to hold for social ideology, but not for economic ideology. These findings provide evidence that the overlap between the religious and the political in the American context may in part be due to underlying principles regarding how to understand and organize society and that these principles may be adopted to satisfy biologically-influenced psychological needs.

    The Higher Power of Religiosity Over Personality on Political Ideology
    (Springer, 2019) Ksiazkiewicz, Aleksander; Friesen, Amanda; Political Science, School of Liberal Arts
    Two streams of research, culture war and system justification, have proposed that religious orientations and personality, respectively, play critical roles in political orientations. There has been only limited work integrating these two streams. This integration is now of increased importance given the introduction of behavior-genetic frameworks into our understanding of why people differ politically. Extant research has largely considered the influence of personality as heritable and religiosity as social, but this view needs reconsideration as religiosity is also genetically influenced. Here we integrate these domains and conduct multivariate analyses on twin samples in the U.S. and Australia to identify the relative importance of genetic, environmental, and cultural influences. First, we find that religiosity’s role on political attitudes is more heritable than social. Second, religiosity accounts for more genetic influence on political attitudes than personality. When including religiosity, personality’s influence is greatly reduced. Our results suggest religion scholars and political psychologists are partially correct in their assessment of the “culture wars”—religiosity and ideology are closely linked, but their connection is grounded in genetic predispositions.
