Abstract

We present evidence for a complex relationship between religiousness and Haidt’s moral foundations, with data from four experiments, measuring 21 different dimensions of personal religiousness and utilizing six different religious primes. The more conservative dimensions of religiousness, such as intrinsic religious orientation and religious attendance, were positively related to binding moral foundations of loyalty, authority, and purity and sometimes related to the individualizing foundation of care. However, other, less conservative dimensions of religiousness, such as quest and extrinsic religious orientations, were unrelated or negatively related to binding foundations. Benevolent God concept was the only religious measure that was positively related to all five moral foundations. We did not find reliable effects of religious primes on endorsement of moral foundations. Results suggest a consistent but complicated relationship between religiousness and moral foundations at a dispositional level.
