Quick Answer

The Estimation Calibrator is a simple web tool that trains you to accurately gauge your prediction confidence, fixing common human biases like overconfidence where people claim 90% certainty but hit only 60-70% accuracy[6][8]. Users improve their Brier score by 10-25% through practice, achieving calibration errors under 5-10% for better decisions in investing, business, or daily life[6][8]. Ideal for professionals and anyone seeking sharper probabilistic thinking.

Why You Need This

Humans struggle with probability estimation calibration, often overestimating confidence by 20-30%, even experts like physicians and forecasters[6][8]. Key stats reveal the gap: 80-90% of untrained people are overconfident, while auditors cut errors from 15-20% to under 10% with training[6][8]. A meta-analysis shows two-thirds misjudge knowledge limits, with 70% overconfidence in trivia estimates[8].

This tool shines for professional forecasters in finance or risk assessment, business decision-makers handling market uncertainties, high-stakes experts in medicine or law, and everyday users improving bets or judgments[6][8]. Overconfidence risks multimillion-dollar mistakes—calibration delivers reliable edges.

How It Works

Answer 50-100 diverse questions on trivia, knowledge, or your field, assigning honest probabilities (e.g., 70%) without extremes like 0% or 100%[6][8]. The tool scores your calibration curve (confidence vs. actual outcomes) and Brier score, revealing biases. Repeat 3-5 sessions to track progress toward a tight curve where 80% claims resolve ~80% correctly[6][8].

Tips for Best Results

  • Tackle varied questions across difficulties for representative sampling[6].
  • Stay honest and consistent—no second-guessing or rounding[8].
  • Run multiple rounds quarterly, plotting curves to sustain gains[6].
  • Adjust habits: If overconfident, downgrade personal 90% to ~70% reliability in real decisions like risks or bets[8].
  • Aim for Brier score below 0.15 and error under 5-10% for elite calibration[6][8].
