Jury System Skill

Specialized knowledge for running synthetic user validation using the Condorcet Jury Theorem.

When to Use

• Validating research findings resonate broadly
• Testing PRD user stories match mental models
• Evaluating prototype usability
• Checking graduation criteria between phases

Core Principle

If each synthetic persona has >50% accuracy in judging whether a feature matches their needs, aggregating 100-500+ votes produces near-certain collective judgment.

Stratified Sampling
