Often, I'm spending months with a person in a very intimate context, getting to know the ins and outs of what they ate for breakfast, not to mention dredging up the most traumatic experiences of their lives, digging through their documents and photographs from difficult times, all of that. And that process, I think, can be extraordinarily strange for subjects who've never been interviewed before, especially if you don't acquaint them from the get-go with what you're trying to do, what it entails, and why you care.
Robertson Davies
The first principle, when you don't know anything about the subject of a thesis, is to let the candidate talk, nodding now and then with an ambiguous smile. He thinks you know, and are counting his mistakes, and it unnerves him. . . the second principle of conducting an oral,. . . is to pretend ignorance, and ask for explanations of very simple points. Of course your ignorance is real, but the examinee thinks you are being subtle, and that he is making an ass of himself, and this rattles him.
