This study assessed the possibility that the Budner (1962) Intolerance of Ambiguity Scale can offer an ideologically biased understanding of religious commitments. In a large sample of university undergraduates (N = 650), Budner Scale correlations with Religious Interest, Religious Orientation, Need for Cognition, and Response Uncertainty supported the conclusion that religion predicts an inability to cope with uncertainty. At the same time, however, special procedures were used to create new scales expressing a Christian Tolerance of Ambiguity by translating Budner Scale items into a language that was more compatible with religious beliefs. These Christian Tolerance of Ambiguity measures revealed that religiousness was associated with an ability rather than an inability to cope with uncertainty. Conflicting results between these Christian and nonreligious Tolerance of Ambiguity measures yielded additional support for the Ideological Surround Model of the psychology of religion.
