A social media echo chamber is when someone is only exposed to information that agrees with their preexisting beliefs. This can happen when people only follow or friend people who share the same opinions, values, and worldview. Social media echo chambers can also be created by algorithms that show users content based on what they have previously liked or engaged with.

As a result, people may never encounter opposing viewpoints and their beliefs may become further reinforced.Detoxing from a social media echo chamber can involve diversifying the types of sources you get your news from and following a wider range of people on social media. It may also involve seeking out information that challenges your existing beliefs in order to broaden your perspective. Detoxing from an echo chamber can be difficult, but it's important to remember that having diverse perspectives is essential for critical thinking and growth.
