THEORY-920: As Mancinelli and Bach's systematic review reports it, rating it B, in three laboratory studies of healthy humans a signalled, costless avoidance response offered for a stimulus never paired with the aversive outcome was used, and withdrawing it raised expectancy of the outcome for that stimulus, though Xia et al. (2019) found no change in skin conductance or startle; every study signalled the response's availability, which may itself have read as a danger cue

Bears onQUESTION-327 — Does available avoidance leave threat expectancy uncorrected in proportion to how few unavoided disconfirming trials it allows, in people with anxiety disorders as in healthy controls, and does performing and then losing an unsignalled avoidance response raise threat expectancy for a stimulus never paired with harm, scaling with how much the person avoided?
SupportsCLAIM-446 — Some persistent anxiety may be governance-maintained rather than belief-maintained: anticipated threat grants defensive processes authority over action, attention and evidence acquisition; under the avoidance that authority selects, the hypotheses that the situation is dangerous and that it is safe predict the same observation, so repeated safety need not correct the threat estimate; relief reinforces the defense without being evidence of danger; and the regime can outlast a corrected belief, its pathology, where present, being defensive authority insensitive to corrective evidence at avoidable cost
Cited as “extends” byTHEORY-1184 — In three laboratory studies of healthy humans, offering a costless avoidance response for a stimulus never paired with the aversive outcome led people to use it, and withdrawing the response then raised their expectancy of the outcome for that stimulus; signalling of the response is a confound

Mancinelli & Bach, LIT-1477, read in full in NOTE-1134 from the PsyArXiv preprint: pp. 19–20 and 26–27, and Fig. 4 (p. 53).

What was actually shown

The review reports that “signalling the availability of a costless AR for a previously and currently never punished CS (i.e., the CS-) has been observed to elicit this AR, and to increase threat expectation once this AR option is removed” (Cameron et al. 2022; Engelhard et al. 2015; Xia et al. 2019), “although CR (SCR and FPS) were not affected (Xia et al., 2019)” (pp. 19–20). It rates the phenomenon B.

The authors argue that this “must invoke an inference mechanism that deduces CS–US contingencies without direct experience: after all, the agent never sees the CS- being followed by punishment” (p. 26). A model-free actor-critic cannot produce it. Their first candidate: people “might counterfactually infer danger for the safe CS, through the artificial belief that if they had not avoided, when they had the chance, they would have been punished” (p. 26). Their second: latent-cause inference, in which the withdrawal of avoidance marks a new context.

What could have come out otherwise: threat expectancy for a stimulus that had never been followed by harm could have stayed at its floor whatever was done about it.

What this does not say

  • That people infer danger from their own avoidance. The review gives that as one explanation. The signal that avoidance is available “might be understood by participants as a signal for US delivery” (p. 19), and every study used one. Signalling is “unusual in real-world or clinical avoidance settings” (p. 26).
  • That the effect reaches fear responses. In Xia et al. (2019), skin conductance and startle did not change; the review does not say whether the other two studies measured them.
  • Anything about anxiety disorders. Healthy participants only.

Connections

  • CLAIM-446. The nearest laboratory case of the claim’s closing inference, “if I felt compelled to protect myself, the danger must have been serious”, by which the governance system becomes a source of evidence for its own appraisal. It also qualifies the claim’s sentence that avoidance “does not strengthen the belief”: in these tasks the availability and withdrawal of avoidance did raise it.
  • LIT-1498, unread, is cited by the claim for danger inferred from one’s own safety behaviour in anxiety disorders, the clinical form of this phenomenon.

Note of 2026-10-30: the dropped clause

The old title said the withdrawal of avoidance raised expectancy “though not their skin conductance or startle in the one study that measured them”. That clause is not kept as a Proposed reading (ADR-047, kind 3). It was imprecise: the review reports only that “CR (SCR and FPS) were not affected (Xia et al., 2019)” (pp. 19–20) and does not say whether the other two studies measured them, so “the one study that measured them” read more into the review than it says. The rest of the old title, the three studies’ finding in the record’s voice, is kept as a Proposed reading that extends this one.
