In a paper that deftly bridges the divide between the humanities and the sciences—C. P. Snow’s much-vaunted two cultures—researchers from the MIT Media Lab document the underlying dynamics of collective attention and memory, traced as a bi-exponential curve (a steep drop followed by a slow decline over time).
The paper published on December 10 in Nature Human Behavior begins with a quotation from one of Pablo Neruda’s most famous poems, “Poema 20,” contrasting the vivid but often short-lived emotion of intense romantic love and its gradual fading from memory as the years pass: “Love is so short, forgetting is so long.” The dynamics of this process, the researchers contend, parallel precisely the attention a society devotes to its most memorable events (whether the Watson–Crick paper on the structure of DNA or Michael Jackson’s Thriller video).
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
