Overview
Predictor Hand is an AI forecasting engine inspired by superforecasting principles. It collects signals, builds reasoning chains, makes calibrated predictions, and rigorously tracks accuracy over time. Category: DataIcon: 🔮
What It Does
1
Collect Signals
Gather data from news, social media, financial markets, and academic sources
2
Build Reasoning Chains
Apply base rates, weigh evidence for/against, identify key assumptions
3
Make Predictions
Generate specific, falsifiable predictions with calibrated confidence levels
4
Track Accuracy
Score predictions when they expire, calculate Brier scores, analyze calibration
5
Generate Reports
Deliver prediction reports with accuracy dashboards and meta-analysis

Basic Setup
Example Workflow
- Collect signals from tech news, social media, company announcements
- Analyze base rates (how often do model releases match predictions?)
- Build reasoning chains for/against each prediction
- Generate 5 calibrated predictions with resolution criteria
- Store predictions in ledger with
resolution_date = 2026-06-30 - When June 30 arrives, research actual outcomes and score accuracy
- Update Brier score and calibration metrics
How It Works
1. Signal Collection
Executes 20-40 targeted search queries based on domain: Technology signals:web_search→ top resultsweb_fetch→ extract claims, data points, expert opinions- Tag signals:
- Type: leading/lagging indicator, base rate, expert opinion, data point, anomaly
- Strength: strong/moderate/weak
- Direction: bullish/bearish/neutral
- Source credibility: institutional/media/individual/anonymous
2. Accuracy Review
For predictions whereresolution_date <= today:
1
Research Outcome
Search for evidence of what actually happened
2
Score Prediction
Correct, Partially correct, Incorrect, or Unresolvable
3
Calculate Brier Score
(predicted_probability - actual_outcome)^2 where outcome is 0 or 14
Update Calibration
Check if your 70% predictions are right ~70% of the time
3. Reasoning Chain Construction
For each potential prediction:4. Cognitive Bias Checks
Before finalizing predictions:- Anchoring — Am I fixating on a salient number?
- Narrative bias — Good story ≠ likely outcome
- Overconfidence — Are my 90% predictions actually 60%?
- Base rate neglect — Did I start with historical frequency?
5. Contrarian Mode (Optional)
Ifcontrarian_mode = true:
- Identify consensus view from collected signals
- Search for evidence contradicting consensus
- Include at least one counter-consensus prediction per report
6. Report Generation
Output
Dashboard Metrics
- Predictions Made — Total predictions ever made
- Accuracy — Percentage of resolved predictions that were correct
- Reports Generated — Number of reports delivered
- Active Predictions — Currently unresolved predictions
Prediction Quality
What Makes a Good Prediction
Good predictions are:
- Specific — “GPT-5 will launch before July 1” not “AI will advance”
- Falsifiable — Clear resolution criteria
- Calibrated — Honest confidence levels (not always 90%)
- Timestamped — Exact resolution date
- Reasoned — Explicit chain of logic
Brier Score Explained
Brier score measures prediction accuracy:- 0.00 — Perfect (predicted 100% and it happened, or 0% and it didn’t)
- 0.25 — Random guessing (50% confidence on everything)
- 1.00 — Worst possible (predicted 100% and it didn’t happen)
Tips & Best Practices
For best forecasting:
- Always start with base rates (historical frequency)
- Show your work — reasoning chains catch errors
- Track ALL predictions — don’t selectively forget bad ones
- Update predictions when new evidence arrives (note updates in ledger)
- Distinguish predictions (testable) from opinions (untestable)
Common Pitfalls
OverconfidenceMost people are overconfident. If you’re above 90% on most predictions, you’re probably overconfident. Narrative bias
A compelling story doesn’t make an outcome likely. Check the base rates. Confirmation bias
Actively search for evidence AGAINST your prediction, not just for it. Anchoring
Don’t fixate on the first number you see. Consider the full range.
