Claim

The amygdala's scanning for danger gives humans a preponderance for focusing on bad news and treating the unfamiliar as dangerous.

Assessment

Leans supported

Score: 0.6982 under ledger-default@0.3.0 at snapshot 27745

3 of 4 review checks done · 3 counted

3 independent evidence lineages · review checks 3 of 4 · stability LOW

Main unresolved issue: 13 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:71eecaf2-6407-837d-886f-da4b5eba0e1e

Not yet independently audited.This assessment depends heavily on modeling choices.A quoted passage from journals.plos.org, nature.com, and pmc.ncbi.nlm.nih.gov was not found on the page when Galedra fetched it.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted support: A review reports imaging and lesion evidence that the amygdala prioritizes processing of threat-related cues. weight 0.540000 evidence

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Leans supported to Leans contradicted.

prior 0.35 → log-odds -0.619039 + 1.458000 (the counted weights) = 0.838961 → probability 0.6982

Under neighbouring settings of the same model: 0.5991 to 0.7818, a spread of 0.1827.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.

Summary

Leans supported. The main support is: A peer-reviewed study supports the broader behavioral components of the claim: people preferentially attend to and retain negative information, and perceived danger is associated with greater credulity toward hazard information. fbf396ee

Qualifier: The passage links the amygdala's danger-scanning to a preponderance for focusing on bad news, but says nothing about treating the unfamiliar as dangerous. d3711a6b

Qualifier: The review supports an amygdala-centered role in prioritizing threat-related information and attention, including some novel or uncertain threats; it does not establish that all humans have a general bad-news bias or that unfamiliar things are uniformly treated as dangerous. 6274638e

Qualifier: An fMRI study found amygdala novelty responses independent of valence, while negative-novelty interaction appeared in the BNST, qualifying a simple amygdala danger-bias explanation. 726a26f6

Qualifier: Human fMRI research supports amygdala sensitivity to unusual or unknown stimuli and allocation of processing resources, but does not by itself establish a general human negativity bias toward all bad news or unfamiliarity. b7fd5282

Qualifier: The review says amygdala activity may reflect emotional intensity rather than valence, qualifying a simple danger-scanning explanation. e69a8ef8
