2.3 Online Filter Bubbles

The most important tool used by Facebook and Google to hold user attention is filter bubbles. The use of algorithms to give consumers “what they want” leads to an unending stream of posts that confirm each user’s existing beliefs. On Facebook, it’s your news feed, while on Google it’s your individually customized search results. The result is that everyone sees a different version of the internet tailored to create the illusion that everyone else agrees with them. Continuous reinforcement of existing beliefs tends to entrench those beliefs more deeply, while also making them more extreme and resistant to contrary facts.
