What Defines a Meme?
Excerpt (via James Gleick @ Smithsonian)
What lies at the heart of every living thing is not a fire, not warm breath, not a ‘spark of life.’ It is information, words, instructions,” Richard Dawkins declared in 1986. Already one of the world’s foremost evolutionary biologists, he had caught the spirit of a new age. The cells of an organism are nodes in a richly interwoven communications network, transmitting and receiving, coding and decoding. Evolution itself embodies an ongoing exchange of information between organism and environment. “If you want to understand life,” Dawkins wrote, “don’t think about vibrant, throbbing gels and oozes, think about information technology.”
“Ideas have retained some of the properties of organisms,” he wrote. “Like them, they tend to perpetuate their structure and to breed; they too can fuse, recombine, segregate their content; indeed they too can evolve, and in this evolution selection must surely play an important role.”
Ideas have “spreading power,” he noted—“infectivity, as it were”—and some more than others. An example of an infectious idea might be a religious ideology that gains sway over a large group of people. The American neurophysiologist Roger Sperry had put forward a similar notion several years earlier, arguing that ideas are “just as real” as the neurons they inhabit. Ideas have power, he said:
Ideas cause ideas and help evolve new ideas. They interact with each other and with other mental forces in the same brain, in neighboring brains, and thanks to global communication, in far distant, foreign brains. And they also interact with the external surroundings to produce in toto a burstwise advance in evolution that is far beyond anything to hit the evolutionary scene yet.
ssey (or at least the idea of the Odyssey), the wheel, anti-Semitism and writing. “Memes have not yet found their Watson and Crick,” said Dawkins; “they even lack their Mendel.”
Yet here they are. As the arc of information flow bends toward ever greater connectivity, memes evolve faster and spread farther. Their presence is felt if not seen in herd behavior, bank runs, informational cascades and financial bubbles. Diets rise and fall in popularity, their very names becoming catchphrases—the South Beach Diet and the Atkins Diet, the Scarsdale Diet, the Cookie Diet and the Drinking Man’s Diet all replicating according to a dynamic about which the science of nutrition has nothing to say. Medical practice, too, experiences “surgical fads” and “iatro-epidemics”—epidemics caused by fashions in treatment—like the iatro-epidemic of children’s tonsillectomies that swept the United States and parts of Europe in the mid-20th century. Some false memes spread with disingenuous assistance, like the apparently unkillable notion that Barack Obama was not born in Hawaii. And in cyberspace every new social network becomes a new incubator of memes. Making the rounds of Facebook in the summer and fall of 2010 was a classic in new garb:
