Vladimir Nabokov was a lepidopterist. No, really. While Proust wasn't actually a neuroscientist - just an extremely intuitive novelist - Nabokov spent six years as a research fellow at the Harvard Museum of Comparative Zoology, obsessing over the details of the Polyommatus blues. Furthermore, his speculative hunch about the evolution of these blue butterfly turns out to have been exactly right. Here's Carl Zimmer:
The surprising accuracy of Nabokov's research helps overturn a longstanding impression among biologists that the novelist was a mediocre scientist, dabbling in insects while waiting for Lolita. Over at Bioephemera, Jessica Palmer has an excellent post on an old Stephen J. Gould essay that castigated Nabokov for his "intellectual promiscuity," his unwillingness to focus exclusively on fiction:
It's worth pointing out that Nabokov himself would have fervently disputed Gould's assertion. The novelist didn't see his butterfly science as wasted effort or academic frivolity. (He frequently described his life pleasures as "the two most intense known to man: writing and butterfly hunting.") Instead, Nabokov saw his arcane butterfly knowledge as a crucial element of his fiction, an intellectual love that inspired many of his literary themes. (Indeed, his fiction is dense with abstruse references to various butterfly and moth species.) As Nabokov noted in Strong Opinions:
How did butterfly research improve the art? Nabokov believed that his background in lepidoptera helped develop his deep passion for detail and precision. The same obsessive interest that helped him catalogue insect species also allowed him to write ecstatically vivid prose, for what Nabokov said about literature is also true of science:
For Nabokov, the entire universe was just an elaborate puzzle waiting to be figured out. It didn't matter if one was talking about a novel or the evolution of an insect or a chess problem: Nabokov knew that the way to solve the puzzle was to focus on the little things, to begin at the beginning and inductively work your way upwards. While Gould saw his dappling in science as a diffusion of his genius, Nabokov (convincingly) argued that his genius was actually a merger of these two distinct disciplines: "I think that in a work of art there is a kind of merging between the two things, between the precision of poetry and the excitement of pure science."
It's also important to note that the advantage of having a "dual-identity" - being both a novelist and a scientist, for instance - isn't limited to Nabokov. According to a study led by Jeffrey Sanchez-Burks, a psychologist at the University of Michigan, people who describe themselves as both Asian and American, or see themselves as a female engineer (and not just an engineer), consistently display higher levels of creativity. In the first experiment, the researchers gathered together a large group of Asian Americans and asked them to design a dish containing both Asian and American ingredients. In the second study, they asked female engineers to design a new mobile communication device.
In both cases, subjects who are better able to draw on their mixed backgrounds at the same time were more creative than those who could only draw on one of their backgrounds. They designed tastier dishes and came up with much better communication devices. Because their different social identities were associated with different problem-solving approaches, their minds remained more flexible, better able to experiment with multiple creative strategies.In contrast, Asian Americans who felt that they had to "turn off" their Asian background in an American setting - this is an example of "low identity integration" - or female engineers who believed that they had to be less feminine to be effective at work, had a harder time drawing on their wealth of background knowledge. Such research makes me particularly hopeful in light of this news on the surge of people who identify as "mixed-race":
The cognitive advantage of having a dual-identity returns us to the reason Gould was wrong about Nabokov. The novelist knew that his art benefited from his science, from his ability to see the world in terms of its gleaming particulars. Nabokov was right about the blue butterflies, but he was also right about his background in lepidoptery. Pluralism is always practical.
