SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you correct overconfidence and underconfidence by aligning your stated certainty with the actual strength and completeness of the evidence behind a claim.

Core Features & Use Cases

  • Confidence calibration workflow: Turns a claim with a stated percentage into an evidence-audited, frequency-tested calibrated estimate.
  • Evidence strength auditing: Separates support into observation, inference, anecdote, and assumption to expose weak foundations.
  • Counter-evidence and failure-mode weighting: Surfaces what would be expected if the claim were true, identifies missing checks, and reweights confidence around the most likely way the claim fails.
  • Use case: When you’re asked “How sure are you?” after making a judgment (e.g., research interpretation, risk assessment, or decision-making), this skill produces a more defensible calibrated confidence level.

Quick Start

Calibrate your confidence for the claim “X is true” with an original confidence of 80% by listing supporting evidence, counter-evidence, the most likely failure mode, and then returning a calibrated confidence percentage.

FAQPage Schema
How do I calibrate my confidence level against available evidence for a judgment?

Confidence calibration aligns your stated certainty with evidence strength by auditing supporting observations, counter-evidence, and failure modes to output a frequency-adjusted calibrated percentage.

What is confidence calibration and when do I need it for risk assessment?

Confidence calibration corrects overconfidence and underconfidence by matching your certainty to actual evidence completeness. You need it when making defensible risk assessments, research interpretations, or decisions.

How do I correct overconfidence in my probability estimates and decision support?

To correct overconfidence, separate your supporting evidence into observations, inferences, anecdotes, and assumptions to expose weak foundations, then apply frequency-based confidence adjustment for a calibrated estimate.

What's the best way to audit evidence strength for a falsifiable claim?

The best way to audit evidence strength is to categorize support into observation, inference, anecdote, and assumption, then surface counter-evidence and identify the most likely failure modes to reweight confidence.

Can I use confidence calibration for decision support without structured evidence?

No, confidence calibration requires structured evidence and counter-evidence auditing, explicit failure-mode identification, and a stated percentage to produce a defensible calibrated confidence level.

Why does my stated confidence percentage need failure-mode identification during evidence auditing?

Failure-mode identification during evidence auditing surfaces what would be expected if the claim were true, identifies missing checks, and reweights your confidence around the most likely way the claim fails.
