Echo chamber (media)

An echo chamber is "an environment where a person only encounters information or opinions that reflect and reinforce their own."[1]

In news media and social media, an echo chamber is an environment or ecosystem in which participants encounter beliefs that amplify or reinforce their preexisting beliefs by communication and repetition inside a closed system and insulated from rebuttal.[2][3][4] An echo chamber circulates existing views without encountering opposing views, potentially resulting in confirmation bias. Echo chambers may increase social and political polarization and extremism.[5] On social media, it is thought that echo chambers limit exposure to diverse perspectives, and favor and reinforce presupposed narratives and ideologies.[4][6]

The term is a metaphor based on an acoustic echo chamber, in which sounds reverberate in a hollow enclosure. Another emerging term for this echoing and homogenizing effect within social-media communities on the Internet is neotribalism.

Many scholars note the effects that echo chambers can have on citizens' stances and viewpoints, and specifically implications has for politics.[7] However, some studies have suggested that the effects of echo chambers are weaker than often assumed.[8]
