Metis — Weigh Evidence
weigh_evidenceReport the full spread of quantified evidence for a research question—including each estimate’s source, page, qualifiers, and missing context—instead of returning one value.
Instructions
What does the evidence in the corpus actually say about a quantity?
Fact-checking a number is not the same as checking a citation. A figure can be
correctly cited and still be one of many the literature reports — this corpus
holds specificity estimates for HAT serology ranging from 72% to 99.7%, and a
single confident answer hides that entirely.
So this reports the SPREAD, never one value: every quantified statement found,
with its document and page, the qualifiers attached to it (sample size,
confidence interval, reference standard, population, setting, threshold), what
is MISSING from each, sentences nearby that complicate the figure, and how old
the evidence is. Deterministic — lexical retrieval and regex, no model, so it
can miss an oddly-phrased figure but cannot invent one.
Use it before answering any "what is the X of Y" question. Then use
`check_for_newer_evidence` to find out whether the corpus is current.
Args:
question: The question as asked, e.g. "specificity of CATT in passive screening".
layers: Comma-separated layer slugs to restrict to; omit to search all.
show: How many individual findings to list (default 14).
Returns:
Per-metric spread, the individual estimates with provenance and
qualifiers, the qualifier gaps, and the evidence date range.
