Catastrophic-forgetting and organizational-forgetting research independently converged on the same corrective move against the jingle fallacy
Read together, claim-catastrophic-forgetting-is-a-structure-dependent-regime-not-universal and claim-david-brachet-2011-splits-forgetting-into-continuous-and-discrete-channels do not describe the same mechanism, and neither literature knows the other exists. At the level of mechanism, the resemblance the vault's embedding search flagged (cosine 0.86, unlinked) is a false friend, joining observation-ml-ad-en-gedi-cosine-pairing-is-embedding-false-friend and observation-hawks-jeffress-cosine-pairing-is-embedding-false-friend as roughly the vault's fourth logged instance of a cosine pairing that shares rhetorical shape rather than causal substance.
But one level up, both fields independently made the same kind of correction to a naive prior. A term — "forgetting" — that looked like it named one phenomenon turns out, on inspection, to split into a catastrophic/discontinuous regime and a graceful/gradual regime, gated by a structural condition specific to the domain: representational task-overlap for neural networks, stay-versus-exit for organizations. This is the general pattern the jingle fallacy names — treating a shared label as evidence of a shared construct, described under that name by Edward L. Thorndike in 1904 and paired with its mirror, the jangle fallacy, by Truman Lee Kelley in 1927 — run in reverse: rather than a fallacy committed and left uncorrected, both the neural-network literature and the David & Brachet decomposition are cases of a field catching and resolving exactly that error about its own central term, without either field being aware the other had done the same thing.

“there are two broad channels through which forgetting at the firm level may occur: the decay of individual skills (Arthur et al., 1998) and labor turnover, whereby experienced employees are replaced by new ones.”
