Kai RYSSDAL: Time now for a little Freakonomics Radio, that moment every couple of weeks we talk to Stephen Dubner, the co-author of the books and the blog, it is the … Here we go. Time now for a little Freakonomics Radio. It’s that moment every couple of weeks we talk to Stephen Dubner, the co-author of the books and the blog of the same name. The hidden side of everything is what he does. Dubner, welcome back.
Stephen J. DUBNER: Hey Kai, thanks for having me back. You know last month, you know, we, New Yorkers, lost a legend, former congressman and mayor, Ed Koch.
RYSSDAL: Oh yeah, yeah, yeah.
DUBNER: Now, Koch was unique is a few ways, including the fact that he actively solicited feedback from the public.
Ed KOCH: Serendipitously, I said on one occasion, “I’m Ed Koch, I’m your congressman, how am I doing?” People stopped to tell me, and I knew I was on to something.
DUBNER: So Kai, this got me to thinking about feedback, generally.
DUBNER: It strikes me that a lot of people say they want feedback, but I’m not so sure they really do, especially if there’s a chance that it will be negative feedback.
RYSSDAL: Yeah, no. Who wants to be told they’re doing something wrong? Forget it.
DUBNER: That’s probably right. But the fact is if you really want to get better at something, it’s hard to do that without feedback, whether it’s your job, or a sport, or schoolwork. So I wanted to know the latest academic thinking on feedback.
RYSSDAL: All right, well give it up. What’d you find?
DUBNER: Well, let’s start with the fact that there are obviously at least two different kinds of feedback, right: positive and negative. As it turns out, they each produce their own benefits. Positive feedback is really helpful when you’re trying to increase someone’s commitment. So let’s say, you know, someone new to a job or a project. Here’s Stacey Finkelstein, a Columbia management professor who’s been studying feedback:
Stacey FINKELSTEIN: For these people, positive feedback is most motivating. It’s what signals that there’s value to what they’re doing, they like what they’re doing, or that they might achieve their goal at some point.
DUBNER: But here’s the thing Kai, once somebody really buys into that goal, positive feedback has diminishing returns. So if you’re looking for actually improvement you’ve got to start going negative. O.K.? Here is Heidi Grant Halvorson, she’s a psychologist also at Columbia:
RYSSDAL: This seems fraught.
Heidi Grant HALVORSON: Look, doling out negative feedback is not fun. It’s embarrassing. We feel terrible. We feel guilty. So we love hearing, “Hey, maybe I don’t have to give negative feedback.” “Maybe I can just say positive things!” “If I just keep saying positive things, then somehow this person will work to their fullest potential and everything will turn out fine.” And that just turns out to not be the case.
RYSSDAL: Well, wait. How do you know that’s not the case?
DUBNER: O.K., well I’ll tell you about the research that Stacey Finkelstein and co-author, Ayelet Fishbach, at the University of Chicago did. They ran a series of experiments with people in a variety of realms, some novices and some experts. And granted, these are only experiments, but this is the best they could do for now. And they wanted to see how different people handled feedback at different stages of their expertise. And the results argue quite strongly that novices really need the positive feedback, but that experts just start to tune it out. So here’s Fishbach:
Ayelet FISHBACH: The more a person is committed to a goal, the more negative compared with positive feedback will be efficient.
RYSSDAL: But Dubner, people are fragile, man! You don’t want to hurt people’s feelings. I come out of the studio, and someone says, “man that interview stunk!” That hurts my feelings!
DUBNER: Well, I guess there are two ways to look at this: you can either look at trying to make people happy or trying to make people better. If you want to make people happy, you know …
RYSSDAL: That’s so cold.
DUBNER: Well, maybe, look, if you don’t want to get better, that’s your prerogative, right? If you do, then it’s critical feedback that’s going to help get you there. Now, I’m not saying you should eliminate positive feedback or that you should, you know, deliver the negative feedback in a way that makes people weep.
RYSSDAL: Well, give me a for instance here, would you?
DUBNER: Oh, I’m so glad you ask, Kai. So as you know, I’m a really big fan of Marketplace. I think you do a great job as a host.
RYSSDAL: Uh-huh, yeah, yeah, yeah, blah, blah, blah.
DUBNER: I would like to look at a couple recent examples of your work. I’ve noticed you are smooth as silk on most domestic matters. But I think you might want to think about practicing your foreign pronunciations a bit more before you get on the air. Here, listen to this one, Kai.
RYSSDAL: All right.
RYSSDAL: If you want to know where those reactors built like Fumu … Fukushima rather, that Alex mentioned …
RYSSDAL: You are so fired! All right, we’re going to turn off your microphone. We’re done.
DUBNER: Hang on. There’s another.
RYSSDAL: No, there’s not.
RYSSDAL: The prospect of a quarter of a million new Romanian-Bulgarians. Romanians, rather, and Bulgarians.
RYSSDAL: What are “Romanian Bulgarians”?
DUBNER: You remember them? And here’s a little something else I think you could maybe improve on, Kai. This is interesting, this is kind of a trademark phrase of yours I’ve found.
RYSSDAL: A final thought on the way out that goes like this … This final note on the way out in which Boris Johnson, the mayor of The City of London … This final note as we leave off today, the end of the beginning.
DUBNER: You’re sensing a pattern here, I gather.
RYSSDAL: I hate you.
RYSSDAL: … This final note on the way out, we did a thing a couple of months ago …
RYSSDAL: You know what? This may be your final note pal.
DUBNER: Possibly, but before I go let me offer the constructive feedback.
RYSSDAL: There’s more?
DUBNER: No, here’s the thing. I have nothing against the “final note” or “on the way out,” but together they’re just redundant. So what about cutting one of them, and just think, Kai? Just think of all the extra time you’ll save over the course of a year, maybe enough time to run an extra couple Freakonomics Radio segments.
RYSSDAL: Or five minutes every two weeks that we don’t have to have you on. How about that? Would that be all right?
DUBNER: Please, no! Please have me back!
RYSSDAL: Stephen Dubner, Freakonomics.com is his website. We’ll see you.
DUBNER: I hope so.
RYSSDAL: Maybe, I don’t know.
