Interviews, especially televised ones, are a performance. You're explicitly not trying to convince the interviewer of anything, you're trying to give a good interview, ostensibly for the benefit of whoever is watching. Politicians, for example, are famous for doing whatever they can, in more and less elegant ways, to talk about the things that they are interested in conveying (the "talking points") and not about whatever it is the interviewer is asking.

This is not the point of this technique. This technique is about actually talking to a person, one-on-one, and trying to understand what they mean. No one else is watching, or at least the interview isn't being recorded.
