An echo chamber can be defined as “an environment where a person only encounters information or opinions that reflect and reinforce their own.” This can be caused by exclusively looking at the same news sources, only talking to certain people who agree with you, and advertisement algorithms. Confirmation bias can increase the likelihood of echo chambers, which is “the tendency to favor info that reinforces existing beliefs.” Echo chambers can happen online and in real life. A “filter bubble” is created when websites track what you click on and how long you stay on certain sites. They use this information to recommend similar articles or sites that will further enforce the opinion you have. Echo chambers cause people to gradually obtain very extreme and polarizing perspectives. Most of the time, echo chambers are caused by the advertisement and news site algorithms that will recommend you articles that will only reinforce your existing views.
