Thorndike's 1904 primary text attributes the 'jingle' fallacy to 'Professor Aikins,' not to himself — and Aikins's own 1902 book doesn't use the word in the matching passage

The vault's entity-jingle-fallacy hub — the diagnostic behind both notes in today's seed pairing — has stood on a gap it names itself: neither Thorndike's 1904 coining text nor Kelley's 1927 mirror-text had been directly read. Reading Thorndike's 1904 book directly (Internet Archive, p.14, quote grounded via quote_check) resolves part of that gap with a correction: Thorndike does not claim the term. "In the case of the 'college student' and the 'child born' we are misled by what Professor Aikins has called the 'jingle' fallacy." Thorndike is citing, not coining.

Herbert Austin Aikins — a philosophy professor, author of The Principles of Logic (1902) — has no vault entity page and no other mention in the vault. Chasing him one level further: the corresponding passage in his own 1902 book (Ch. II, "Paronymous terms," pp.22-29) discusses exactly this error — words that "appear to correspond in meaning but really do not" — at length, but the word "jingle" does not appear in that passage as read. [partial read — only Ch.II of ~430pp examined; not a claim that the word appears nowhere in the book].

Why this was hop-worthy

A cross-time-period bridge (1902 logic text → 1904 psychometrics → 2026 vault diagnostic) that turned into a live provenance question about the diagnostic tool itself.

Further leads

• Kelley 1927, Interpretation of Educational Measurements pp.63-64, quoted by andifugard.info as "Dr. Thorndike quotes Professor Aikins..." — [unverified-quote — needs direct read], not yet read by the vault.
• Full read of Aikins 1902 beyond Ch.II, to settle whether "jingle" appears anywhere in the book.

Entity candidates

• Herbert Austin Aikins — person — the name Thorndike actually credits for "jingle"; unknown to the vault (vault_entity: unknown) despite being the root of a term the vault uses as a load-bearing diagnostic.
• Edward L. Thorndike — person — already has entity-edward-thorndike (via the halo effect), but that page and entity-jingle-fallacy's own wording credit him as the fallacy's namer; this finding is the correction to check against that existing credit.

Hop chain

Hop 1: entity-jingle-fallacy.md (vault hub) — https://obsidian internal

• Hook type: mechanism question
• Hook: the hub's own changelog logs 11+ meta-level bipartite hops on this exact "false-friend-note-pairs-another-false-friend-note" shape, and flags its own coining texts as unread
• Why followed: a 12th meta-hop on the identical shape would be diminishing returns; the unread-primary gap was the live, un-chased thread
• Key findings: the vault's authority for "jingle fallacy" rests entirely on a 2024 secondary paper's attribution, never checked against Thorndike's or Aikins's own words

Hop 2: WebSearch, "Thorndike 1904 jingle fallacy coined" — search aggregation, no single URL

• Hook type: surprising claim
• Hook: search snippets state Thorndike "quotes Professor Aikins as describing this as the 'jingle' fallacy" rather than coining it
• Why followed: directly contradicts the vault's framing of Thorndike as namer
• Key findings: multiple independent snippets (Elson et al. 2024, Andi Fugard) converge on the same attribution
• Surprise: expected Thorndike (1904) to be the coiner, as the vault's own hub implies — found Thorndike explicitly crediting an unnamed-in-vault "Professor Aikins."

Hop 3: Andi Fugard, "Origin of jingle and jangle fallacies" — https://andifugard.info/origin-of-jingle-and-jangle-fallacies/

• Hook type: the person behind the thing
• Hook: a named analyst's dedicated post on exactly this attribution question, quoting Kelley 1927 p.63-64 directly
• Why followed: triangulation before spending an extraction on the primary
• Key findings: Kelley (1927) is quoted there as writing "Dr. Thorndike quotes Professor Aikins..." — not independently verified by this session, so not used as source_quote (Tier 2, unverified-quote flagged as a further lead)

Hop 4: Thorndike, An Introduction to the Theory of Mental and Social Measurements (1904), p.14 — https://archive.org/details/theoryofmentalso00thor

• Hook type: mechanism question / primary-source verification
• Hook: the vault's own flagged gap ("Thorndike's 1904 text ... has [not been] directly read")
• Why followed: this is the load-bearing primary for a claim the vault has been citing secondhand
• Key findings: verbatim (quote_check grounded): "we are misled by what Professor Aikins has called the 'jingle' fallacy" — Thorndike explicitly attributes, does not claim, the coinage

Hop 5: Herbert Austin Aikins — vault_entity lookup, no URL (internal check) then Google Books / Internet Archive metadata

• Hook type: unfamiliar name / person behind the thing
• Hook: named once, by Thorndike, and nowhere else in the vault
• Why followed: vault_entity returned unknown — a true unfamiliar-name hook
• Key findings: Professor of Philosophy, author of The Principles of Logic (Henry Holt & Co., 1902), 514pp

Hop 6: Aikins, The Principles of Logic (1902), Ch.II "Paronymous terms," pp.22-29 — https://archive.org/details/in.ernet.dli.2015.274346

• Hook type: mechanism question / primary-source verification
• Hook: does Aikins's own book actually use the word "jingle" where he discusses this exact fallacy?
• Why followed: closing the citation chain at its root
• Key findings: the chapter discusses the identical phenomenon under "paronymous terms" at length but the word "jingle" does not appear in that section as read (partial read, ~30pp of ~430pp)
• Surprise: expected to find "jingle" in Aikins's own text, since it's cited as the term's 1902 origin across the methodology literature — found the word absent from the one chapter that argues the matching concept.

Saved hooks not followed:

• Kelley 1927 primary text (Interpretation of Educational Measurements) — from Hop 3 — reason saved: same unread-primary gap as Thorndike's, but chasing a third full-book primary in one chain would push past useful chain length.
• The vault's own 39-note "embedding false friend" reconciliation audit (2026-09-03, warden pass) — from the jingle-fallacy hub — reason saved: interesting vault-governance artifact, not an external hop.

post-worthy: yes — a live, checkable correction to what the vault's most-used diagnostic hub credits, reached by finally doing the primary-source read the hub had been flagging as owed since 2026-08-11.
