If, for example, an interviewee said in all seriousness "I want to shoot all dogs and make the poor eat their babies" would you expect the interviewer to go go "Hmmm very interesting. Why do you think that?"
No.
It is vital that interviewers challenge the subject. Especially when they say something profoundly ludicrous or disturbing. Otherwise they might has well just be in PR.
Actually yes if a interviewee said something like that I’d like to know why they’re saying that because it doesn’t make sense to me!
Sometimes it helps for institutions to point out the the emperor has no clothes. The social reinforcement of norms is hugely influential.
The risk, of course, is that you don't get invited back. That's "The Test" in the post.
Saying "Well, our listeners can decide for themselves" is a cowardly cop-out.
You might not be able to change the interviewee's mind but you can sure as hell send social signals to your audience that you condemn their views or think they're ludicrous.
Case in point - why are you trying to change my mind here? You're pushing back because you want to signal to others that my point of view is incorrect. That sort of basic interrogation seems completely missing in (especially American) media.
Why wouldn't you do the same if I said something outrageously offensive in public?
It could be argued the role of an interviewer is to present and understand the interviewee and their views, to dig deep into their unique knowledge.
An interview which is just “it’s sunny outside, isn’t it” isn’t a very good interview, and neither is one where the interviewee says “I genuinely believe there is a portal to heaven and hell in the butthole of my pet chicken” and the interviewer moves to the next question without a followup.
You don’t need to debate a guest to challenge their views.
> I listened to this, I marked what a ridiculous metaphor that was, and how inapplicable it is the to topic of learning math, and didn't need Ezra to call it out.
A good interviewer wouldn’t just “call it out” to the audience, they would ask the interviewee to expand on the topic. They would put themselves in the shoes of their viewers (who the interview is for) and ask what is interesting to them.
Doing that well should inevitably involve challenging your guest's framing of certain issues. As an absurd example, if you ask the guest why they spin around 3 times when they stand up and they say, "better that than doing three somersaults", you would be doing your audience a huge disservice by asking your guest how they assess the relative difficulty of spins versus somersaults.
Why Jensen Huang thinks a fabulously wealthy person not knowing their own address is analogous to a child not learning basic math skills would be, in my opinion, much more interesting and informative of his viewpoint than the actual point he was trying to make.
