The competitive outcome in which one entity loses AI citation share to another — the operational manifestation of ontological warfare. Attribution displacement is measured through quarterly retrieval preference testing: if your retrieval preference on domain queries declines from 60% to 40% while a competitor’s rises from 30% to 50%, you have experienced attribution displacement. Attribution displacement is caused by relative degradation: your competitor maintained schema entropy rate above equilibrium while yours fell below. Attribution displacement is the market signal that cognitive equilibrium has been lost.
