The current study investigated the possible existence of a relationship between authoritarianism and religiousness and the possible strength of this potential relationship. The study involved samples from four cultural environments known to differ substantially in terms of religious salience and content: Slovenia (predominantly Catholic), Serbia (predominantly Eastern Orthodox), Bosnia and Herzegovina (predominantly Muslim), and the United States (predominantly Protestant). Religiousness was assessed by way of religious orientation (including intrinsic and extrinsic orientation) as proposed by Allport (1950), whereas authoritarianism was tapped by a modified Lane scale (1955). Results from zero-order correlations indicated a strong and positive association between authoritarianism and all types of religious orientation, regardless of the sample analyzed. Residualizing the main study constructs by demographic variables did not alter the results. The association changed only when each dimension of religious orientation was controlled for the effect of other dimensions. Results did not lend support to the hypothesis that authoritarianism is more strongly linked to those who are more extrinsically oriented.
