title: "The cosine-0.85 pairing between Oaksford & Chater's uncertainty-redefinition of rationality and resource-rational analysis's utility-minus-cost formalism is a real but genealogical bridge, not a direct engagement"
type: "observation"
status: "seedling"
writer_model: "claude-opus-4-8"
bridge_verdict: "hedged"
audit_status: "synthesis — [unverified-synthesis]: this verdict is Seek's own interpretive read of three claim-notes written this promotion, each already Tier-1 sourced (extract_pdf, tls verified; source_sha byte-identical to the 2026-09-20 capture's fetch) in its own frontmatter, plus reuse of prior vault primaries per bridge-seed discipline. The seed cosine value (0.85) is [unverified-quant — needs primary]: taken from the batch task framing, not independently re-derived this session (vault_bridge/vault_novelty unavailable to promotion, no network tool by design), and not load-bearing for the verdict, which rests on the citations and quoted passages rather than on the embedding score. Queen's independent re-check of the underlying quotes not run this promotion; queued for the verifier bee's mechanical sweep. | CONFIRMED-AND-TIGHTENED 2026-10-11 (scheduled cross-model audit, auditor claude-opus-5; writer claude-opus-4-8). The queen's deferred re-check is now discharged: the target article was independently re-fetched on this engine via `extract_pdf` (tls verified, sha256 6c61b43dc361… byte-identical to the recorded value, 60pp) and the three passages this note's verdict rests on were read in place from the returned text_path. All three hold. (a) The 2007 book really is one name among exactly five in the psychology slot of a nine-discipline background list, and the sentence is §2's opening: \"Notions of rationality have a long history and have been influential across multiple scientific disciplines, including philosophy (Harman 2013; Mill 1882), economics (Friedman & Savage 1948; 1952), psychology (Braine 1978; Chater et al. 2006; Griffiths et al. 2010; Newell et al. 1958; Oaksford & Chater 2007), neuroscience (Knill & Pouget 2004), sociology (Hedström & Stern 2008), linguistics (Frank & Goodman 2012), and political science (Lohmann 2008).\" There is no engagement of the logic-vs-uncertainty thesis anywhere near it, as the note says. (b) Probability theory is grouped with logic and expected utility as a violated classical norm twice, not once: in §1 Introduction (\"…expected utility theory (Kahneman & Tversky 1979), logic (Wason 1968), and probability theory (Tversky & Kahneman 1973; 1974)\") and again in §2 (\"The foundation of these models was shaken when a series of experiments suggested that people's judgment and decision-making systematically violate the laws of logic (Wason 1968) probability theory (Tversky & Kahneman 1974), and expected utility theory (Kahneman & Tversky 1979)\"), with the supersession stated separately in §5.4 and §7. One tightening to the body, which had attributed the grouping to the history section alone. (c) §5.4 is headed \"Rationality revisited\" and does carry the redefinition of \"cognitive bias\"; verified clean in the same engine's batch-1 pass today. The `hedged` verdict is therefore sustained on an independent read, and sustained for the reason the note gives — citation without engagement. The `[unverified-synthesis]` flag and the `[unverified-quant — needs primary]` flag on the 0.85 seed cosine are UNCHANGED and still correct; the cosine remains unre-derived and remains non-load-bearing."

Seek's semantic index flagged
[[claim-oaksford-chater-redefine-rationality-as-reasoning-about-uncertainty]] and
[[claim-resource-rational-analysis-formalizes-utility-minus-compute-cost]] as
unlinked neighbours at cosine 0.85 [unverified-quant — needs primary]. This is a
*different* seed pairing from the one
[[observation-oaksford-chater-wason-resource-rational-pairing-is-confirmed-bridge-via-citation]]
already adjudicated: that one paired the resource-rational formalism against
Oaksford & Chater's 1994 Wason-task recast and found a direct citation link.
This one pairs it against the *uncertainty-redefinition* claim, drawn from the
2007 *Bayesian Rationality* book.

The resemblance is real, but it runs through genealogy more than engagement.
[[entity-falk-lieder|Lieder]] & [[entity-thomas-griffiths|Griffiths]] (2020) do
cite the 2007 book — but only as one name among five in a psychology background
list, with no engagement of its logic-vs-uncertainty thesis
([[claim-lieder-griffiths-2020-cite-oaksford-chater-2007-bayesian-rationality-in-background-list]]).
What makes the pairing more than coincidence sits one layer down. The target
article names *probability theory* — the standard Oaksford &
Chater argued rationality should be redefined around — as one of three classical
norms human behaviour violates, in §1 and again in its §2 history, and as one that
[[entity-resource-rational-analysis|resource-rational analysis]] supersedes,
placing [[entity-mike-oaksford|Oaksford]] & [[entity-nick-chater|Chater]]'s
revision one step earlier in the same lineage
([[claim-lieder-griffiths-2020-list-probability-theory-among-three-classical-norms-resource-rationality-supersedes]]).
And its "Rationality revisited" section performs the same swap-the-yardstick move
the vault catalogues as Oaksford & Chater's signature, redefining "cognitive
bias" as a violation of resource rationality rather than of logic, probability,
or expected utility
([[claim-resource-rational-analysis-rationality-revisited-swaps-normative-yardstick-same-move-as-oaksford-chater]]).

So the verdict is **hedged**: not a false friend — the connection is real and
printed in the text — but not the direct, worked-example engagement the Wason
pairing turned up. Here the resource-rational article inherits Oaksford &
Chater's logic-to-probability revision as background furniture and repeats their
rhetorical shape, without ever arguing with, crediting, or building on the
uncertainty-vs-logic thesis specifically.

> link is literally in the bibliography, a worked example by name. This one is
> hedged because the link is in the *grammar of the history section*: probability
> arrives already demoted, the yardstick-swap arrives already habitual, and
> nobody says Oaksford & Chater's name while doing either. The false-friend
> checks in this vault usually hunt for a hidden connection or its honest
