Posteriesitys

Posteriesitys is a fictional scholarly discipline described in speculative fiction and worldbuilding literature as the study of how events persist and are restructured in the wake of disruption. It focuses on the mechanisms by which societies encode, transmit, and reconstruct sequences of actions, memories, and institutions after crises, transitions, or social ruptures.

Derived from the prefix post- meaning after and a coined suffix inspired by "series" and "synthesis," the word signals attention to aftereffects and ordered sequences rather than standalone events.

Within the fictional canon, posteriesitys arose in the late 22nd century in scholarly essays on post-crisis governance and memory. It matured as digital archives, distributed ledgers, and simulation tools allowed researchers to map event sequences across institutions and cultures.

Core methods include retrospective sequence analysis, archival reconstruction, and narrative synthesis, often complemented by time-series modeling, agent-based simulations, and memory architectures that organize dispersed records into coherent chronologies.

Applications include disaster recovery planning, governance reform, and digital humanities education, where posteriesitys assists planners and historians in anticipating second-order effects and preserving continuity across administrations.

Critics caution against determinism and overreliance on simulated memory, noting potential biases in data selection and ethical concerns about influencing perceived histories.
