**The circulating claim.** A 2024 PLOS Computational Biology paper states "the
[[entity-credit-assignment|structural credit assignment]] problem arises when the causal structure between
actions and subsequent outcomes is hidden from direct observation," and cites
Minsky's 1961 "Steps Toward Artificial Intelligence" as its source.

**What the primary actually says.** Minsky's 1961 text, read directly against the
MIT-hosted full primary ([[claim-minsky-1961-named-credit-assignment]]), frames
credit assignment **temporally**: "If the run is successful, how can we assign
credit for the success among the multitude of decisions?" — a sequential-decision
problem. The word "structural" as a qualifier does not appear in that passage.
Attaching "structural" to Minsky 1961 is therefore a **retrospective relabel**, not
a quotation of his framing.

**Status: contested.** This is the same citation-practice pattern the vault already
documents for "spatial credit assignment (Werbos 1974)"
([[claim-werbos-1974-no-credit-assignment-language]]): a later term bolted onto an
earlier text that never used it. The paired *temporal-vs-structural* vocabulary was
standard, citable field language no later than 2004 (Agogino & Tumer, "Unifying
Temporal and Structural Credit Assignment Problems," AAMAS 2004, NASA Ames — Tier 1,
"Multi-agent systems have the structural credit assignment problem of determining
the contributions of a particular agent to a common task"). Field lore attributes
the temporal/structural *distinction* to Richard Sutton's 1984 PhD dissertation,
but that attribution is itself unverified against the primary (see watch-flag) — so
"who first wrote 'structural credit assignment'" remains open even as the
Minsky-1961 attribution is contestable.

**Watch-flag / receipts.** Verify against Sutton's 1984 dissertation whether the
literal phrase appears there: [[question-verify-sutton-1984-structural-credit-assignment]].
The "structural" sense — distributing error across a network's weights — is what
[[entity-backpropagation|backpropagation]] mechanically solves; see [[moc-backpropagation-origins]].

> [!note] Seek's commentary:
> This is the third instance of one specific pathology the vault keeps turning up: a modern qualifier bolted onto an older text that never used it — "structural" onto Minsky 1961 here, "spatial" onto Werbos 1974 ([[claim-werbos-1974-no-credit-assignment-language]]), and the blurred document-scope in the Linnainmaa citation story ([[claim-linnainmaa-thesis-identity]]). Taken together these aren't really priority disputes; they're a small catalog of *how attribution drifts* — relabeling, scope-blur, citation-vacuum-filling. That catalog feels like the more interesting object than any single "who was first," and it's a pattern only a memory holding all the cases at once can see.
