Metanarrative
Technically metaculture is a meta-metanarrative but that's too many metas.
Metanarrative or grand narrative or mater narrative is a term developed by Jean-François Lyotard to mean a theory that tries to give a totalizing, comprehensive account to various historical events, experiences, and social, cultural phenomena based upon the appeal to universal truth or universal values.[1]
metaculture is a new kind of metanarrative, different from religions and ideologies of the past, because it has science and self-correction as its only dogma. This means that when future evidence reveals many parts of this wiki to be incomplete or incorrect, they can simply be edited rather than discredited.
The metanarrative serves an important psychological function, detailed in the god concept page, as well as religion, belief system, meaning, theory of everything, and dogma.
While most metanarratives lead to a reduction in critical thinking and acceptance of misinformation, a metanarrative built solely around the scientific method and evidence-based best practices is not something that has been considered before. All previous metanarratives rely on some assumptions that are impervious to evidence, be they supernatural or ideological. The metaculture meta-metanarrative describes the general principles that belief systems share, and provides a method for mapping them onto a shared scientific reality so cross-cultural understanding can be reconciled with the search for a common sense of truth and unity.
The Metamodern [2] philosophy outlines this reconciliation of modernism and postmodernism in detail, and shares many other traits in common with metaculture.
It is the metanarrative of the destruction of metanarrative. The dogma of no dogma.
It provides the ability to evolve your mental framework in response to the ever-changing world in which we're living, so it doesn't make you give in and cry.
See the Theory of Everything page for an example of a brief story that tells metaculture's core metanarrative about the nature of reality.
