Creationist Paleontologist on Economics

The NYTimes reports on a guy getting his degree in paleontology even though he's a "New Earth Creationist." How does he justify his situation?

For him, Dr. Ross said, the methods and theories of paleontology are one “paradigm” for studying the past, and Scripture is another. In the paleontological paradigm, he said, the dates in his dissertation are entirely appropriate. The fact that as a young earth creationist he has a different view just means, he said, “that I am separating the different paradigms.”

He likened his situation to that of a socialist studying economics [my emphasis] in a department with a supply-side bent. “People hold all sorts of opinions different from the department in which they graduate,” he said. “What’s that to anybody else?”

My question is, in his analogy, which is more like scripture: socialism, or supply-side economics?
