Stent's 'here-and-now prematurity' applies the concept to hypotheses of unresolved or contested truth value, not only to vindicated discoveries

Read against his own 1972 Scientific American text, Gunther Stent's concept of prematurity is broader than the retrospective, "correct-but-neglected" reading that claim-stent-prematurity-covers-neglected-not-contested-ideas originally carried. Stent defines a discovery as premature when its implications "cannot be connected by a series of simple logical steps to canonical, or generally accepted, knowledge" — a criterion he then applies independently of the discovery's truth value. Asking whether the concept "pertain[s] only to retrospective judgments made with the wisdom of hindsight," he answers: "No, I think it can be used also to judge the present," and names this forward-looking application "here-and-now prematurity."

His worked case is the 1960s claim that memory could be transferred between animals via injected macromolecules — experiments Stent himself reports "have been difficult to repeat, and the results claimed for them may indeed not be true at all." He nonetheless calls the theory premature: "The lack of interest of neurophysiologists in the macromolecular theory of memory can be accounted for by recognizing that the theory, whether true or false, is clearly premature." He extends the same logic to ESP, arguing a hypothesis can be premature — unconnectable to canonical knowledge, and therefore properly ignored by working scientists — regardless of whether it is eventually vindicated or refuted.

This complicates, without overturning, the vault's inherited scope condition. Stent's retrospective paradigm cases (Avery, Mendel, Polanyi) are all vindicated discoveries — see claim-stent-prematurity-exemplars-avery-mendel-polanyi-are-vindicated-discoveries — but they are the concept's best-known instances, not its full stated scope. The narrower reading is what observation-hawks-jeffress-cosine-pairing-is-embedding-false-friend leans on to exclude claim-hawks-2007-human-adaptive-evolution-accelerated-recently from being called "premature"; that exclusion holds for Stent's vindicated exemplars but not for his own prospective "here-and-now" usage, which admits present-tense claims of unknown truth value. The concept therefore sits less cleanly at the head of the delayed-vindication cluster (claim-jeffress-1948-place-theory-waited-decades-for-anatomical-confirmation, claim-sleeping-beauties-delayed-recognition-is-a-continuum) than the original note implied.
