The Filter Bubble: What the Internet Is Hiding From You

Everything which bars freedom and fullness of communication sets up barriers that divide human beings into sets and cliques, into antagonistic sects and factions, and thereby undermines the democratic way of life.

—John Dewey

Since the 1960s, a group of researchers, including Donald Campbell and Dean Simonton, has been pursuing the idea that at a cultural level the process of developing new ideas looks a lot like the process of developing new species. The evolutionary process can be summed up in four words: “Blind variation, selective retention.” Blind variation is the process by which mutations and accidents change genetic code, and it’s blind because it’s chaotic—it’s variation that doesn’t know where it’s going. There’s no intent behind it, nowhere in particular that it’s headed—it’s just the random recombination of genes. Selective retention is the process by which some of the results of blind variation—the offspring—are “retained” while others perish. When problems become acute enough for enough people, the argument goes, the random recombination of ideas in millions of heads will tend to produce a solution. In fact, it’ll tend to produce the same solution in multiple different heads around the same time.

As University of Virginia media studies professor and Google expert Siva Vaidhyanathan writes in “The Googlization of Everything”: “Learning is by definition an encounter with what you don’t know, what you haven’t thought of, what you couldn’t conceive, and what you never understood or entertained as possible. It’s an encounter with what’s other—even with otherness as such. The kind of filter that Google interposes between an Internet searcher and what a search yields shields the searcher from such radical encounters.” Personalization is about building an environment that consists entirely of the adjacent unknown—the sports trivia or political punctuation marks that don’t really shake our schemata but feel like new information. The personalized environment is very good at answering the questions we have but not at suggesting questions or problems that are out of our sight altogether. It brings to mind the famous Pablo Picasso quotation: “Computers are useless. They can only give you answers.”
