The cosine-0.85 pairing between the vault's optimization-as-theory-of-mind and Gigerenzer's-not-optimization notes is a confirmed bridge, mediated by rational analysis rather than a direct Werbos–Gigerenzer exchange
Seek's semantic index flagged claim-optimization-as-theory-of-mind-two-lineages
and claim-gigerenzer-camp-defines-ecological-rationality-as-not-optimization
as unlinked neighbors at cosine 0.85 [unverified-quant — needs primary; taken
from the batch task framing, vault_bridge not independently re-run this
session]. Testing whether the resemblance is a real mechanism or an
embedding
false friend, direct comparison finds it real — but the connective
tissue already exists in the vault one note over, so this was never a hidden
link, only a missing direct edge.
The mechanism is a shared third node. One seed note documents two independent disciplines — Werbos's optimal-control ADP ("the concept of optimization… can be a useful tool in serious efforts to understand consciousness and the mind," claim-werbos-1997-optimization-consciousness-chapter) and Anderson's rational analysis, in Oaksford & Chater's flagship Bayesian application of it — both betting on optimization as a theory of mind. The other seed note documents Gigerenzer's camp declining that same bet by name: "optimization models have been used to argue in favor of human rationality, as in Bayesian models of cognition." "Bayesian models of cognition" is the family rational analysis is the flagship instance of. So both seed notes are already one hop from claim-rational-analysis-anderson-optimal-solution-marr-level — the load-bearing hinge — which is why observation-ecological-rationality-and-rational-analysis-are-contested-not-compatible already exists as the vault's synthesis of the Gigerenzer side without ever having been cross-linked to the Werbos side.
The link is mediated, not a direct exchange: two targeted web searches run
in the 2026-09-17 capture (not in this note's own offline promotion run)
surfaced no citation traffic in either direction between the optimal-control/ADP
literature and Gigerenzer's ecological-rationality
program [unverified — absence-of-evidence, search-based]. The two lineages
appear genuinely independent, meeting only through the rational-analysis node
each already touches — the same species of already-mapped bridge as
observation-gates-jevons-liang-1979-olsder-1975-cosine-pairing-is-confirmed-bridge.
This reading agrees with both sibling captures (the 2026-07-11 "bridge
holds, one note over" and the 2026-07-31 "contested, not compatible").
