“This Will Make You Smarter,” a 2012 book edited by John Brockman, consists of a series of around 150 short essays from intellectuals in a variety of disciplines, all answering the question “What scientific concept will improve everybody’s cognitive toolkit?” The text is online in its entirety, since it was originally published there. Here’s a little of one essay that I recently browsed through and enjoyed.
Creativity is a fragile flower, but perhaps it can be fertilized with systematic doses of serendipity. Sarnoff Mednick showed decades ago that some people are better than others at detecting the associations that connect seemingly random concepts: Asked to name a fourth idea that links “wheel,” “electric,” and “high,” people who score high on other measures of creativity will promptly answer “chair.”
More recently, research in Mark Jung-Beeman’s lab at Northwestern has found that sudden bursts of insight — the Aha! or Eureka! moment — comes when brain activity abruptly shifts its focus. The almost ecstatic sense that makes us cry “I see!” appears to come when the brain is able to shunt aside immediate or familiar visual inputs.
I do this remote-reading exercise on my own time, since it would be hard to justify to newspaper editors during the work day. But my happiest moments this autumn came as I reported an investigative article on how elderly investors are increasingly being scammed by elderly con artists. I later realized, to my secret delight, that the article had been enriched by a series of papers I had been reading on altruistic behavior among fish (Lambroides dimidiatus).
If I do my job right, my regular readers will never realize that I spend a fair amount of my leisure time reading Current Biology, the Journal of Neuroscience, and Organizational Behavior and Human Decision Processes. If that reading helps me find new ways to understand the financial world, as I suspect it does, my readers will indirectly be smarter for it. If not, the only harm done is my own spare time wasted.
In my view, we should each invest a few hours a week in reading research that ostensibly has nothing to do with our day jobs, in a setting that has nothing in common with our regular workspaces. This kind of structured serendipity just might help us become more creative, and I doubt that it can hurt.
