Online personalization tailors web pages and content to individual users based on their characteristics and preferences, keeping users entertained but potentially trapping them in an "echo chamber" where they are only exposed to similar views. By accepting personalization, people insulate themselves from differing perspectives, potentially closing their minds and making it harder to learn new things. To escape echo chambers, users need to be aware of personalization's effects and intentionally expose themselves to content outside their comfort zones, such as articles with opinions different than their own.
