's personalized news stream. According to Pariser, users get less exposure to conflicting viewpoints and are isolated intellectually in their own informational bubble. Pariser related an example in which one user searched Google for "BP" and got investment news about British Petroleum while another searcher got information about the Deepwater Horizon oil spill

Pariser defined his concept of filter bubble in more formal terms as "that personal ecosystem

s". Other terms have been used to describe this phenomenon, including "ideological frames" or a "figurative sphere surrounding you as you search the Internet." The past search history is built up over time when an Internet user indicates interest in topics by "clicking links, viewing friends, putting movies in your queue, reading news stories" and so forth. An Internet firm then uses this information to target advertising to the user or make it appear more prominently in a search results query page. Pariser's concern is somewhat similar to one made by Tim Berners-Lee in a 2010 report in The Guardian

effect which happens when Internet social networking sites were walling off content from other competing sites––as a way of grab a greater share of all Internet users––such that the "more you enter, the more you become locked in" to the information within a specific Internet site. It becomes a "closed silo of content" with the risk of fragmenting the Worldwide Web, according to Berners-Lee.

Pariser in The Filter Bubble warns that a potential downside to filtered searching is that it "closes us off to new ideas, subjects, and important information" and "creates the impression that our narrow self-interest is all that exists." It is potentially harmful to both individuals and society, in his view. He criticized Google

 for offering users "too much candy, and not enough carrots," He warned that "invisible algorithmic editing of the web" may "limit our exposure to new information and narrow our outlook." According to Pariser, the detrimental effects of filter bubbles include harm to the general society in the sense that it has the possibility of "undermining civic discourse" and making people more vulnerable to "propaganda and manipulation." He wrote:

Reactions

There are conflicting reports about the extent to which personalized filtering is happening and whether such activity is beneficial or harmful. Analyst Jacob Weisberg writing in Slate Magazine did a small non-scientific experiment to test Pariser's theory which involved five associates with different ideological backgrounds conducting the exact same search -- the results of all five search queries were nearly identical across four different searches, suggesting that a filter bubble was not in effect, which led him to write that a situation in which all people are "feeding at the trough of a Daily Me" was overblown. Book reviewer Paul Boutin did a similar experiment among people with differing search histories, and found results similar to Weisberg's with nearly identical search results. Harvard law professor Jonathan Zittrain disputed the extent to which personalization filters distort Google

s were added to Google search engines to deliberately "limit personalization and promote variety."

Nevertheless, there are reports that Google and other sites have vast information which might enable them to further personalize a user's Internet experience if they chose to do so. One account suggested that Google can keep track of user past histories even if they don't have a personal Google account or are not logged in to one. One report was that Google has collected "10 years worth" of information amassed from varying sources, such as Gmail, Maps, and other services besides its search engine, although a contrary report was that trying to personalize the Internet for each user was technically challenging for an Internet firm to achieve despite the huge amounts of available web data.

Related concepts

The filter bubble concept is similar to a phenomenon in which people and organisations seek information which is initially perceived as relevant but which turns out to be useless or on in fact only partially useful, and avoid information perceived as irrelevant but which turns out to be useful. The problem happens because the real relevance of a particular fact or concept in these cases is only apparent only after that fact has become known. Before that, the idea of learning a particular fact may have been dismissed because of a misperception of irrelevance. Accordingly, the information seeker is trapped in a paradox
