Your Brain Puts Strangers on Teams, and the Feed Shows You the Worst Ones
Without the shared ties of real life, disagreement becomes identity, and platforms profit by serving up the posts most likely to enrage you.
Kurzgesagt – In a Nutshell · The Internet is Worse Than Ever – Now What?The problem with the internet may not be that you never hear the other side. It may be that you hear the worst version of it, over and over, until you cannot take the rest seriously.
Researchers call the pattern social sorting. Without conscious choice, your mind files people with different views onto rival sides. In real life, that instinct is softened by shared context. A neighbor may vote differently, but he also roots for your local sports club, goes to your church, or chats at the school gate. Online, that glue is missing. A stranger is just a username and an opinion you dislike, so disagreement becomes a central part of that person's identity.
Once the teams are set, the brain keeps score unfairly. People who share your worldview feel likable and familiar, so you tend to trust their opinions and dismiss bad news about them without much thought. People on the other team get the opposite treatment. Unfavorable claims about them tend to be accepted with little skepticism, and you grow much less likely to seriously consider their position in the future.
Then the business model makes it worse. Social platforms want to hold your attention for longer stretches, and anger drives interaction best. Stronger outrage leads to more sharing and participation, so the system boosts the harshest and most divisive posts. It shows the worst disagreement it can find.
Once teams are set, the feed makes this sorting worse. Because you already view people as rival sides, you treat those harshest views as typical of the entire opposing side. One cruel post becomes proof of what millions of strangers must be like, and every angry share tells the system to find an even worse one.
Questions people ask
Isn't the internet just a filter bubble where I only see people who agree with me?
Studies of what people actually view online found little evidence of ideological isolation. Extreme filter bubbles are rare. The place where people are most ideologically isolated is real life, among friends, family, colleagues, and neighbors.
Why is anger more engaging than other emotions?
Platforms earn more when people stay longer, and anger is the most engaging emotion. Stronger outrage leads to more sharing and participation.
Would smaller online communities really be less angry?
Yes, that is the argument: the older internet of bulletin boards, forums, and blogs had no engagement algorithms, and it was split into thousands of small communities with their own rules that people could leave for another. That structure may reduce social sorting.
