E1 Elements - available group identities

Topic

The elements of this track are the group identities available to a population—political, ethnic, religious, or generational—the strength with which each individual identifies with their group, and the perceived distance from the out-group. None of these elements stands in isolation; they depend on inputs received from other Sociophysics tracks via specific entry points.

This track receives narrative fragmentation from the Worldview mode and perceived inequality from Sociophysics Track 5 (Kinship Intensity). It is this very narrative fragmentation—which describes how the ideological field splits into mutually incompatible legitimizing narratives—that supplies the available group identities with content for distinguishing themselves from the out-group; and it is perceived inequality—arising from the same dynamics of concentration and social mobility described by that other track—that fuels the strength of individual identification with the group, as higher perceived inequality makes membership in a specific stratum or group more salient relative to others.

In turn, this track transmits the degree of polarization to the Sociophysics Conflict mode and feeds audience fragmentation back to the Worldview mode, creating a feedback loop with the very track that originally supplied the narrative fragmentation. This feedback connection completes the cycle: narrative fragmentation from the Worldview mode fuels the available group identities in this track, and the audience fragmentation resulting from the polarization of those identities circles back to deepen the original narrative fragmentation—all without either track requiring an additional mechanism to sustain the cycle. The available group identities thus serve as the foundation for the affective polarization index, network homophily, and perceived social distance—metrics already captured by this track’s diagnostic framework. Any shift in the drivers of narrative fragmentation or perceived inequality is ultimately reflected in one of these three indicators; conversely, any change in the strength of group identification or perceived distance from the out-group alters the degree of polarization this track feeds into the conflict dynamic and the audience fragmentation that, in turn, reinforces the "Worldview" component.
