What the Intrinsic Scale actually measures is religiosity importance, not Allport’s concept

Evidence

In summary, I think the nine Intrinsic items-response sets aside-assess in various ways the importance of one’s religion, in a nonsocial sense. But again, that is not what Allport meant by an intrinsic orientation. And even if the test did measure being committed to the essential, inherent, core de la core message in a faith, that will not necessarily make one less prejudiced. — Bob Altemeyer, The Authoritarian Specter, 2034
