Filter Bubble

A filter bubble is a term term coined by the Internet activist Eli Pariser to refer to a state of intellectual isolation[1] that can result from personalized searches when a website algorithm selectively guesses what information a user would like to see based on information about the user, such as location, past click-behavior and search history. https://en.wikipedia.org/wiki/Filter_bubble (cf algorithmic feed)
