Context collapse
Every post is read by audiences it wasn't written for.
Context collapse describes what happens when audiences that are normally separate end up reading the same message. Offline, people naturally adjust their tone for each setting, joking with old friends, speaking carefully at work, sharing differently with family. On a public profile, all of those groups can see the same post at the same moment.
The term was developed by researchers studying social media, notably Alice Marwick and danah boyd, who looked at how people imagine their audience when they post. The core problem is that different groups expect different things. A joke that depends on shared history reads very differently to someone without that history, and no single wording can satisfy everyone at once.
The trap is becoming so worried about every possible reader that you stop sharing anything. Awareness is meant to guide your choices, not freeze them. Many people settle on keeping separate spaces for separate circles, such as a private group for close friends and a public profile for professional updates, and accept that each space has its own scope.
Context collapse also explains why old posts resurface badly. A message written for one moment and one group can be found years later by a completely different audience, read without any of the original context.
Example
You post a sarcastic comment about your exhausting week, meant for friends who know you love your job. A distant relative takes it at face value and messages your mother, worried you are miserable. The same words carried two meanings depending on who read them, and the platform showed them to both.

Before your next post, picture the least familiar person who could see it, and decide whether this is the right place for it.
