The claim
A20 §1: with memory M, evidence E and a cue q(E, a) that an anchor a helps set, the judgement is J = δ(Retrieve(M, q(E, a)), E). “The anchor can change the judgment without adding any valid evidence about the target.” A19 §6: “communication changes not only what information a receiver is given, but the addressing conditions under which existing information becomes recoverable.”
The psychology is not new, though its retrieval step is inferred rather than measured (note of 2026-10-15). Strack and Mussweiler (LIT-1064) and Mussweiler and Strack (LIT-1078) hold that considering an anchor makes anchor-consistent knowledge more accessible to the later judgement. A20: “The new contribution we might pursue isn’t ‘anchoring affects retrieval.’” What is the record’s is placing it in the pragmatic-transport line: a rendering’s effect on a receiver includes what it makes reachable, not only what it carries.
The record holds the mechanism A19 reached for. LIT-269 (Bricken and Pehlevan, read in NOTE-242) shows attention approximates Kanerva’s sparse distributed memory, so a change of query changes what is read out from an unchanged store.
What it bears on
- CLAIM-199: usable information is relative to the rules a receiver can apply. This adds the cue that selects which apply.
- CLAIM-117: A20 §6 noted that if a frame changes what is accessible, frame A then B may differ from B then A, “a possible mechanism for order effects”. It “does not, by itself, establish noncommutativity in the specific empirical sense proposed by the claim.”
- CLAIM-184: an anchor that is easy to reach is reached often. “accessibility is not the same as warrant.”
What it does not say
Not that all anchoring is selective accessibility. A20 named insufficient adjustment and response effects as rival pathways, and said they need not exclude one another.
Note of 2026-10-15: what the anchoring readings leave standing
Three readings bear on the psychological form this claim cites.
- Strack and Mussweiler 1997 (LIT-1064, NOTE-877). With the anchor number fixed, the anchor’s effect depended on what the comparison made available and whether it applied to the later judgement. But no study measures retrieval. And their model has two stages: accessibility is “not sufficient to guarantee its use and determine the direction of its influence”, and Study 2 turned the same activated knowledge into contrast. So a frame acts on retrieval and on evaluation, and these designs do not separate the two. The defeat condition is restated so that it does not assume they can be.
- Harris et al. 2019 (LIT-1067, NOTE-876). Five preregistered replications (N = 128 each) of Mussweiler and Strack’s lexical-decision test of accessibility found large anchoring and no accessibility effect, and the same tasks failed to detect direct picture priming. The authors conclude the method is unfit as a test, not that the theory is false, and that the earlier evidence from it “is not a strong part of the evidence base”. Their leading account of durable anchoring is a provisional answer formed at the comparison and recalled later, which sits exactly on this claim’s unresolved split: if the carrier is a recalled number, the frame acts on what is answered, not on what is reachable.
- Mussweiler and Strack 1999 (LIT-1078) could not be fetched.
The claim stays Proposed. Its psychological form is a theory with indirect support, and the communicative extension rests on it.
Note of 2026-10-15: split under ADR-043
ADR-043’s pilot found this claim compound: an empirical claim about anchoring in judgement tasks, and the record’s interpretive extension to communication in general. The empirical half is now CLAIM-315, on which this claim rests, and this claim is marked interpretive. Its title already states the general form, so it was kept; what changed is that its psychological support is a separate claim with its own warrant and standing.
