最新一期的Freakonomics Radio有如下一段对话，扎心
LEVITT: Well, a lot of academics has nothing to do with the real world. The kind of stuff I do is related to the real world, but it’s always a little bit off. I’ve had dozens of papers where I thought, wow, this is important. This could have a real impact on people. And nothing has ever happened. Zero. The final straw about academics is about three years ago, I embarked on three different research papers, all of which I thought were really important. And the other day I got onto Google Scholar and I thought, I just want to look and see how much they’ve been cited. And I went through them, and the sum of the citations across those three papers was six. And I said to myself, wait a second. I just spent three years pouring my heart into something that has basically been read by six academics and nobody else in the world. What am I doing?

DUBNER: Levitt, you’re much smarter than me, but I’m gonna share something with you that I think you may find useful. This is obvious to me, but apparently you never thought of it. Nobody reads academic journals. People listen to podcasts. So if you want to reach the people, and make change in the world, I suggest you get on this podcast a little bit more. I mean, if you wanted to, you could sit in my chair for a week and take it over and do whatever you want. And that will be heard by a lot more than six people. You like that idea?
