Religious orientation is two independent dimensions, not one continuum.

Evidence

This model ran into problems early on, when Allport and Ross (1967) found that the extrinsic and intrinsic scales were not measuring opposite ends of the same continuum, as had been assumed, but defined two independent dimensions of personal religion. Associations with prejudice could be due to either or both of the underlying independent dimensions. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 2542

• DEFINE: Clarifies that extrinsic and intrinsic religious orientations are conceptually independent axes, not opposites on a single scale.
