The origin of this framework is in Simulacra and Simulation by sociologist Jean Baudrillard.
Simulacrum Levels are a framework for analyzing different motivations people can have for making statements.
Simulacrum Level 1: Attempt to describe the world accurately.
Simulacrum Level 2: Choose what to say based on what your statement will cause other people to do or believe.
Simulacrum Level 3: Say things that signal membership to your ingroup.
Simulacrum Level 4: Choose which group to signal membership to based on what the benefit would be for you.
