Very interesting read. The final part is a bit of a stretch: I have long argued that degree-granting programs should employ "fire-walking" as a last exam. The chair-person of the program should wait on the far side of a bed of red-hot coals while a degree candidate is forced to walk over the coals. If the candidate's belief in physics is strong enough that the feet are left undamaged, the chairperson hands the candidate a graduation certificate. The test would be more revealing than traditional final exams. I think it should actually reveal the candidate's belief in his/her knowledge of physics, rather than his/her belief in physics.
