A podcast I’ve been enjoying lately is Conversations With Tyler, hosted by the economist Tyler Cowen. It’s recorded from live interviews at George Mason University, and his guests all have their specialties yet are also able to talk knowledgeably about a broad range of topics from science and technology to economics and Russian literature. Cowen’s end of the conversation is almost entirely in the form of rapid-fire (but no less thoughtful) questions.
Podcast have at least one thing they ask every single guest, and Cowen’s is this: Explain the [name of guest here] production function.
A production function, in economics, is a formula that describes how a company or economy’s inputs relate to their outputs. How labor and raw materials, for instance, turn into steak burritos. Thinking about production functions on an individual human basis is great twist. It’s asking: What do you do differently from others that enables you to create what you create? How does what happens in private line up with what happens in public?
Here’s Cowen posing the question to science writer/humorist Mary Roach:
COWEN: Now, you have six main books out, and they’ve all been very successful. Forgetting about what might be your central talent intellectually, but just in terms of your work habits or schedule or how you organize what it is you do, I would call it the Mary Roach production function. How would you describe to us the Mary Roach production function? What is it you do that you think other people maybe could learn from?
ROACH: I am essentially a massive filtration system. So when I begin a project, I don’t know where I’m going. I don’t know what will be in the book. I know that my job is to cherry-pick the most interesting, surprising, funny, bizarre material within this quite broad topic that I’ve selected.
So there may be mornings when I … For Bonk [her book about sex research], I recall going to the basement of UCSF Medical School Library where they had the Journal of Sex Research, which started sometime in the late ’50s, I believe, and going through every table of contents and going, “Boring, boring, boring … Oh! Masturbation is a potential treatment for intractable hiccups.”

ROACH: And then running off to the Xerox machine, or these days, taking a picture.
