“One of the best ways to understand how filters shape our individual experience is to think in terms of our information diet. As sociologist danah boyd said in a speech at the 2009 Web 2.0 Expo: Our bodies are programmed to consume fat and sugars because they’re rare in nature.... In the same way, we’re biologically programmed to be attentive to things that stimulate: content that is gross, violent, or sexual and that gossip which is humiliating, embarrassing, or offensive. If we’re not careful, we’re going to develop the psychological equivalent of obesity. We’ll find ourselves consuming content that is least beneficial for ourselves or society as a whole.”
