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: Data
Icon: 🔮

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

Configure your forecasting domain:

Example Workflow

Predictor Hand will:
  1. Collect signals from tech news, social media, company announcements
  2. Analyze base rates (how often do model releases match predictions?)
  3. Build reasoning chains for/against each prediction
  4. Generate 5 calibrated predictions with resolution criteria
  5. Store predictions in ledger with resolution_date = 2026-06-30
  6. When June 30 arrives, research actual outcomes and score accuracy
  7. Update Brier score and calibration metrics

How It Works

1. Signal Collection

Executes 20-40 targeted search queries based on domain: Technology signals:
Financial signals:
For each result:
  • web_search → top results
  • web_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 where resolution_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 1
4

Update Calibration

Check if your 70% predictions are right ~70% of the time
Example:

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)

If contrarian_mode = true:
  1. Identify consensus view from collected signals
  2. Search for evidence contradicting consensus
  3. Include at least one counter-consensus prediction per report
Example:

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)
Goal: Keep Brier score below 0.20 for good forecasting.

Tips & Best Practices

Never express confidence as 0% or 100% — Nothing is certain. Use ranges like 5-95%.
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

Overconfidence
Most 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.
