Social media today depends on building echo chambers (a.k.a filter bubbles) that gather users in like-minded digital communities. These bubbles create higher levels of engagement, but come with pitfalls - current algorithms used by social media mean that people more often encounter news stories and information that they enjoy - the effect can decrease a person’s exposure to diverse opinions and perspectives. To enable a healthy environment for information sharing, social deliberation, and opinion formation, citizens need to be exposed to sufficiently diverse viewpoints that challenge their assumptions, instead of being trapped inside filter bubbles.
