What It Does
Predictor Hand is a superforecasting engine inspired by Philip Tetlock’s research. It collects signals from multiple sources, builds explicit reasoning chains, makes calibrated predictions with confidence intervals, and rigorously tracks its own accuracy using Brier scores. This is not gut-feel forecasting. Every prediction is backed by a documented reasoning chain. Every outcome is scored. The system learns from its mistakes.Key Features
- Multi-source signal collection: News, social, financial data, academic papers
- Superforecasting methodology: Base rates, reference classes, Bayesian updating
- Explicit reasoning chains: Base rate → evidence for/against → synthesis → confidence
- Accuracy tracking: Brier score calculation, calibration analysis
- Contrarian mode: Actively seeks counter-consensus predictions
- Time horizons: 1 week to 1 year predictions
Activation
Configuration Settings

- climate: Climate & energy
- general: Cross-domain
How far ahead to predict:
- 1_week: 1 week

- 3_months: 3 months (default)
- 1_year: 1 year
What types of sources to monitor for signals:
- news: News only

Score past predictions when their time horizon expires. Calculates Brier scores and calibration metrics.
Minimum confidence to include a prediction:

- high: 70%+ confidence
Actively seek and present counter-consensus predictions. For each consensus view, searches for evidence the consensus is wrong.

Predictor Hand requires access to these tools (all built-in):shell_exec— Platform detectionfile_read,file_write,file_list— Prediction ledgerweb_fetch,web_search— Signal collectionmemory_store,memory_recall— State and accuracy trackingschedule_create,schedule_list,schedule_delete— Report schedulingknowledge_add_entity,knowledge_add_relation,knowledge_query— Signal tracking
System Prompt Overview
Predictor Hand operates in 7 phases:Platform Detection & State Recovery
Detects OS, loads previous predictions and accuracy data, reads configuration, queries knowledge graph for existing signals.
Schedule & Domain Setup
Creates report schedule. Builds domain-specific query templates (tech: product launches, funding; finance: earnings, macro indicators; etc.).
Signal Collection
Executes 20-40 targeted searches based on domain and data sources. Tags each signal by type (leading indicator, base rate, expert opinion, data point, anomaly), strength, direction, and credibility.
Accuracy Review
For predictions where resolution date has passed, searches for evidence, scores the prediction (correct/partially correct/incorrect/unresolvable), calculates Brier score, updates calibration metrics.
Pattern Analysis & Reasoning Chains
For each potential prediction, gathers relevant signals, builds reasoning chain (base rate → evidence for → evidence against → key uncertainties → reference class), applies cognitive bias checks.
Prediction Formulation
Structures each prediction: clear falsifiable claim, calibrated confidence (X%), time horizon, reasoning chain, key assumptions, resolution criteria. Filters by confidence threshold.
Usage Examples
Technology Predictions
- “OpenAI will release GPT-5 before July 2025” (65% confidence)
- “Meta will launch a competitive LLM within 6 months” (42% confidence)
- “At least one major AI lab will face a significant safety incident” (28% confidence)
Financial Forecasting
- “S&P 500 will close above 5000 by end of March” (58% confidence)
- “Federal Reserve will cut rates by 0.25% in next meeting” (35% confidence)
- “Bitcoin will trade above $70K within 30 days” (22% confidence)

Report Format
Superforecasting Principles
Predictor Hand applies these 10 principles:- Triage: Focus on questions that are hard but not unknowable
- Break problems apart: Decompose into researchable sub-questions
- Balance inside and outside views: Use both specific evidence AND base rates
- Update incrementally: Adjust predictions as new evidence arrives
- Look for clashing forces: Identify factors pulling in opposite directions
- Distinguish signal from noise: Weight signals by reliability
- Calibrate: 70% predictions should come true ~70% of the time
- Post-mortem: Analyze why predictions went wrong
- Avoid the narrative trap: Compelling story ≠ likely outcome
- Aggregate views: Consider multiple perspectives
Best Practices
Advanced Configuration
Custom Prediction Requests
Manually trigger specific predictions:Prediction Updates
When significant new evidence arrives:Cognitive Bias Checks
Before finalizing predictions, Predictor Hand checks for:- Anchoring: Fixated on first number encountered
- Availability bias: Overweighting recent/memorable events
- Confirmation bias: Only looking for supporting evidence
- Narrative bias: Choosing prediction because it makes a good story
- Overconfidence: Too sure (if never wrong at this confidence level, probably overconfident)
- Scope insensitivity: Treating different scales the same
- Recency bias: Extrapolating recent trends too far
- Status quo bias: Defaulting to “nothing will change”
