Fantasy Football Hygiene Scorecard: Noise + Silver Bayesian Integration
This scorecard combines decision hygiene from Noise (Kahneman/Sibony/Sunstein) with Bayesian updating from Nate Silver. It forces structured, low-noise evaluation in slow drafts—decomposing judgments, using outside views/priors, aggregating evidence, and resisting intuition until the end.
How to Use the Scorecard (Slow Draft Process)
Pre-Draft: Build priors for player archetypes (rookie RB, veteran WR, etc.) from historical data.
On the Clock (or Daily Review): Fill one row per player. Spend 15–45 minutes max per key decision.
Scoring: Use 1–10 scales or % probabilities. Keep components independent.
Final Decision: Only after all columns → compare Posterior Value vs. ADP.
Audit: Re-score the same player on different days to check your own noise.
Column Explanations:
Prior: Pure outside view (historical base rates). Do this first.
Decomposition: Noise MAP—score factors separately before combining (e.g. weighted average: 40% floor + 30% ceiling + etc.).
Evidence & Likelihood: Silver-style update. Quantify how much new info moves you from the prior (and how reliable it is).
Posterior: Blended result. Include probabilistic ranges (Silver emphasis).
Value vs ADP: Relative judgment—key for draft position.
Decision Hygiene Check: Quick yes/no audit to reduce your personal noise.
Start with Prior (185 pts).
Evidence moves it down modestly because small-sample preseason is noisy.
Posterior is more calibrated than raw hype would suggest.
Benefits for Variance Reduction
Noise Reduction: Decomposition + hygiene check prevents holistic snap judgments and occasion/pattern noise.
Silver Calibration: You avoid overreacting to camp buzz while still updating.
Slow Draft Power: Revisit the scorecard as news evolves—your valuations become consistent and data-driven.
Long-Term Edge: Track completed scorecards across seasons. Managers using similar structured processes show lower decision variance and higher win rates in multi-year studies.
Pro Tip for Your Science of Fantasy Football: After 5–10 drafts, analyze scorecard accuracy (how often your posterior ranges captured actual outcomes). This meta-audit further quiets your personal noise.
