Thoughtlessly obeying is undoubtedly a sign of incompetence; a doctor must always use judgement based on patient's condition and not rely on a bunch of numbers, a doctor told me in my teens. However, ordering tech based tests is not thoughtless all the time, at least not with competent doctors. I mean, in this age of self diagnosing based on googling, a doctor not ordering such tests would be seen as incompetent, and even ignorant. Would a doctor risk his reputation, and possibly livelihood, just to prove a point, even when his spidey senses tells him there is nothing severe about the patient's condition when the patient insists on it, directly or indirectly? Only a House would do so. The writer is too eager to generalize for some reason.
