Economist Paul Krugman’s appearance at last year’s Worldcon received a couple paragraphs of analysis in a lengthy profile by Larissa MacFarquhar for The New Yorker.

“Last August, Krugman decided that before he and Wells departed for a bicycle tour of Scotland he would take a couple of days to speak at the sixty-seventh world science-fiction convention, to be held in Montreal. (Krugman has been a science-fiction fan since he was a boy.) At the convention, there was a lot of extremely long hair, a lot of blue hair, and a lot of capes. There was a woman dressed as a cat, there was a woman with a green brain attached to her head with wire, there was a person in a green face mask, there was a young woman spinning wool. There was a Jedi and a Storm Trooper. Those participants who were not dressed as cats were wearing T-shirts with something written on them: “I don’t understand—and I’m a rocket scientist,” “I see dead pixels,” “Math is delicious.” Krugman has always had a nerdy obsession with puns….

Krugman explained that he’d become an economist because of science fiction….. “If you read other genres of fiction, you can learn about the way people are and the way society is,” Krugman said to the audience, “but you don’t get very much thinking about why are things the way they are, or what might make them different. What would happen if ?”
