Primes¶
- Cognitive Entrenchment
- In emergency settings, where time pressure amplifies reliance on the dynamic vs static expertise, premature closure — stopping diagnostic search after the first plausible hypothesis — is a major error mode.
This sourceCatalogs diagnostic cognitive biases including premature closure (stopping search after the first plausible hypothesis).
Supported in partVerified against the publisher's abstract
Croskerry's abstract supports cognitive biases as a source of diagnostic error, but does not itself name premature closure or emergency time pressure.
“A critical subset of diagnostic errors arises through cognitive errors, especially those associated with failures in perception, failed heuristics, and biases; collectively, these have been referred to as cognitive dispositions to respond (CDRs).”

- Emotional Reasoning
- Over-testing then produces findings (false positives, incidental abnormalities) that appear to validate the original emotional inference.

- Law of the Instrument
- Diagnostic medicine and statistics: the cardiologist, gastroenterologist, and neurologist see heart, GI, and nervous-system problems in one chest-pain patient, and the Bayesian, frequentist, and ML practitioner see prior-choice, test-construction, and feature-engineering problems in one dataset.
This sourceCatalogs diagnostic cognitive dispositions including anchoring and specialty-driven framing, whereby a clinician's repertoire shapes which diagnosis a presentation (e.g., chest pain) is read as — supporting the cardiologist/gastroenterologist/neurologist specialty-bias instance.

The abstract backs the general principle that a clinician's own biases and failed heuristics shape the diagnosis reached, but names no specialties, instruments, or chest-pain example.

- A clinical radiologist reviewing chest X-rays for signs of cancer.
This sourceCatalogues cognitive dispositions to respond and diagnostic-error patterns in clinical practice; documents how working-memory load and attentional fragmentation jointly elevate diagnostic-error rates.

- Einstellung Effect
- Expertise and chess cognition — grandmasters shown positions with both a familiar tactical motif and a hidden superior combination disproportionately play the familiar one; eye-tracking shows gaze never reaches the squares the better solution requires, locating the foreclosure at perception. Medical diagnostic reasoning — the "premature closure" / anchoring tradition: once a clinician retrieves a familiar diagnosis matching some presenting features, the differential narrows and contradicting evidence goes unweighed; the two communities name one effect.

Mechanisms¶
- Diagnostic Category System
- Its central failure mode is premature closure — locking onto the first plausible category and stopping the search, so contradicting evidence is explained away rather than weighed.
This sourceDefines premature closure as accepting an initial diagnosis before verification and discounting contradictory evidence.
- Its central failure mode is premature closure — locking onto the first plausible category and stopping the search, so contradicting evidence is explained away rather than weighed.
- Diagnostic Debiasing Check
- Because it is tied to catalogued error patterns and calibrated against outcomes, it targets the failures that actually occur rather than bias in the abstract.
This sourceCatalogues recurrent cognitive error patterns in diagnosis and describes debiasing strategies aimed at those concrete diagnostic failures.

- Diagnostic Differential
- It is the natural antidote to premature closure — the diagnostic error of settling on the first plausible explanation and then reading all further evidence as confirmation.
This sourceDefines premature closure as accepting a diagnosis before it is fully verified and describes the related failure to revise an initial impression when later evidence arrives.

- Diagnostic Logic Check
- Its failure mode is premature closure
This sourceDefines premature closure as accepting a diagnosis and ending consideration of reasonable alternatives before the diagnosis is fully verified.
- Its failure mode is premature closure
- Diagnostic Narrowing
- Its signature failure is premature closure
This sourceDescribes diagnostic premature closure as anchoring early, favoring confirming information, and stopping before a diagnosis is fully verified.

- Diagnostic Narrowing Protocol
- Its failure mode is that the same speed invites premature closure:

- Diagnostic Pattern Checklist
- Its strength is that it directly attacks the single most common cognitive error in expert recognition — premature closure, the tendency to stop at the first plausible label — by making the alternatives impossible to skip.
This sourceDefines premature closure as accepting a diagnosis before it has been fully verified and failing to continue considering alternatives.
- Its strength is that it directly attacks the single most common cognitive error in expert recognition — premature closure, the tendency to stop at the first plausible label — by making the alternatives impossible to skip.
- Diagnostic Possibility Map
- Its strength is convergence without tunnel vision: by holding the whole differential visible and attaching a test to each branch, it fights the single most common diagnostic error — premature closure, latching onto the first plausible cause and stopping the search.

- Diagnostic Tree Pruning
- It misleads through premature closure: crossing a branch off on a finding that felt decisive but was not, then failing to reopen it as contradicting evidence accumulates.

- Differential Diagnosis
- Premature closure (anchoring on the first plausible cause and stopping) and its mirror, confirmation bias, run the method backwards: start from the favoured diagnosis and collect only features that fit it.

- Its failure mode is diagnostic momentum: a label written into a handoff hardens as it is relayed, each reader trusting the last and no one re-examining the evidence, so a tentative "probably a backup job" quietly becomes fact by the third shift.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 4 of 20 citations: 4 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
