2. The claim, in full

PV mechanism: thalamo-amygdala precedence; Interpreter backward justification

This is a summary-only entry. The text above is the register summary, not the full statement of the claim.

3. What it rests on

No confidence intervals are recorded for any figure in this block.

4. Sources

5. Counter-evidence

6. Why this grade

Three independent lines converge: anatomical (dual-route architecture, rodent), electrophysiological (human intracranial, two studies, two latencies, two stimulus conditions including unconscious presentation), and behavioural-imaging (motivated reasoning, selective and stake-dependent).

The grade rests on the PRECEDENCE claim — that affective appraisal begins before and shapes conscious deliberation — not on any specific anatomical route. Precedence is not in dispute in the literature. The specific subcortical pathway is contested, and is graded separately.

Westen's neutral-figure control is what raises this above PROBABLE. The same brains reasoned accurately when nothing identity-relevant was at stake. That rules out a general-competence explanation and establishes the failure as selective and stake-dependent — which is the framework's actual claim.

The register defines ESTABLISHED as: Supported directly by primary texts or published findings.

7. Correction history

No correction events are recorded. The entry's status is ACTIVE: no later entry amends, supersedes or withdraws it.

10. Open questions

What would strengthen it
a Westen-design replication with a politically balanced sample; intracranial recording during identity-threatening rather than face-threat stimuli; a measure of the interval between limbic onset and reported subjective certainty.
What would falsify it
demonstration that the Westen partisan asymmetry reverses or vanishes under incentivised accuracy; evidence that cold-reasoning circuitry IS recruited during identity-protective processing and is merely overridden downstream, which would make this a suppression account rather than a non-recruitment one.
