Introduction
The rules that determine what gets attention on social platforms are often called “algorithms,” but algorithms are only part of the story. Another way to understand social platforms is as social protocols, or sets of formal and informal rules that communities use to allocate their collective attention.
Like parliamentary procedure or courtroom rules, social protocols shape conversations: they determine what topics are discussed and which voices are heard. Understanding these protocols can help explain phenomena we see in social networks—like filter bubbles, polarization, and misinformation—and suggest ways social protocols could be engineered to promote healthier outcomes.
