I don't know in detail how theologians think. My formal training really stopped with my Christian confirmation and honorary Bible at age 13. My best exposure to credentialed theologians was at Cornell--but I merely heard them speak at our Sunday on campus morning worship service for 5 years. I've had only a tad of philosophy as an undergraduate, but I did pass a qualifying test that entitled me to teach several classes of philosophy at the undergraduate level. I know enough about who they are and what they do to recognize that they think about their problem areas at levels well above my pay grade.
I understand the scientific method as a practicing scientist--and my specialty area is research design. Most of my doctoral students don't have any meaningful knowledge of the scientific method until they design ad carry out their own dissertations. One can't fake an understanding of the scientific method.
