[[observation-vaults-in-between-bridge-category-not-exactly-named-by-located-literature]]
records a negative finding — no located term exactly names the vault's middle
bridge pole (two investigations sharing a method across unconnected referents,
with no author juxtaposing them). That finding is flagged
`[unverified — could not confirm or deny after search]`. The single most
promising lead not yet chased to primary is **Ian Hacking's "styles of
scientific reasoning"** (Hacking 1982, "Language, Truth and Reason," building
on A. C. Crombie's *Styles of Scientific Thinking in the European Tradition*).

## Why it matters

The negative finding is load-bearing: it is the direct answer to the capture's
core question and the note the bridge-taxonomy cluster will cite as "the vault
checked whether its middle category is named elsewhere; answer so far, no." A
"style of reasoning" is a *way of finding things out* (statistical, taxonomic,
postulational, laboratory, and so on) that recurs across otherwise unconnected
scientific domains without those domains being causally linked — which is,
at the *general philosophy-of-science* level the capture asked about,
conceptually the closest thing found to "same method, unconnected domains."
If Hacking's category (or its later elaboration by Hacking, Crombie, or the
subsequent literature) covers the vault's configuration, the negative finding
softens toward a positive borrow; if it imports its own assumption the vault's
bridges lack — as "parallel demonstration of theory" and "structural
equivalence" both did — that sharpens the negative finding into a checked,
three-way "no."

## What I'd need to answer it

- A direct read of Hacking's own primary text on styles of reasoning
  (Hacking 1982, and/or *Historical Ontology*, 2002, which collects the
  style essays), not a secondary synthesis — the capture surfaced this term
  only via WebSearch synthesis of secondary discussions, which under the
  vault's quote-provenance rule is a lead, not a source.
- A check of whether a "style" is predicated of *domains/communities* rather
  than of *individual investigations*: the likely mismatch is that a style is
  a shared culture many practitioners inhabit, whereas the vault's bridges are
  two isolated studies with no shared culture at all.
- Secondary candidates already logged in the capture's "Further leads" if
  Hacking misses: Wittgenstein's "family resemblance" (judged a looser fit —
  names a relation among *concepts*, not *investigations*), and Robert Yin's
  case-study "literal vs. theoretical replication" distinction.

## Candidate next move

Route to the topic queue as a definitional/philosophy-of-science read against
a primary. On resolution: if a term covers the vault's category, add it to
the observation note's body and discharge the `[unverified]` flag toward
`budding`; if the read comes back empty after a genuine attempt, record that
as a firmed "checked three literatures, no exact name found" finding rather
than leaving this open indefinitely. Do not force closure — a partial answer
gets a dated progress line here, not a status flip.

## Progress

- **2026-09-27:** The Hacking half of this question is answered. A direct
  primary read of Hacking's "Language, Truth, and Reason" (1982) confirms the
  mismatch this note anticipated — see
  [[claim-hackings-styles-of-scientific-reasoning-does-not-name-vaults-bridge-category]]
  and [[claim-hacking-derives-styles-from-crombies-six-fold-taxonomy]]. A
  "style" is predicated of a whole tradition or community across its own
  historical genealogy, not of two isolated, independently-motivated
  investigations — a specific, primary-sourced failure mode, distinct from
  the two previously-checked near-misses. This closes the Hacking lead
  specifically; the broader question in this note's title — whether *some
  other* general philosophy-of-science term names the vault's category — is
  not resolved and stays open. The two secondary candidates this note already
  named as fallbacks (Wittgenstein's "family resemblance," Yin's
  literal-vs-theoretical replication) remain unchased. Leaving `status: open`.
