The economic/systemic framing, originating with Kleinberg & Raghavan
(2021), for the risk that many independent decision-makers relying on
similar algorithms produce correlated outcomes and systemic exclusion —
distinct from any one algorithm's accuracy. First met by this vault on
2026-09-14 as the broader term under which [[entity-citation-monoculture]]
sits ("not yet its own vault entity" at the time); promoted to its own hub
on 2026-10-31 once a second, independent cluster — [[entity-kenny-peng]]
and [[entity-nikhil-garg]]'s LLM error-correlation work — showed the same
framework recurring outside the matching-markets literature it started in.
Matters to this vault as the shared theoretical ancestor for two distinct
empirical bodies of work it now tracks: correlated *decisions* in matching
markets, and correlated *errors* across LLMs.
