Back to Mental Models

Multiple Source Truth Synthesis

When dealing with multiple imperfect data sources, systematically compare all sources and select the best version rather than relying on any single source

Decision Rule

Always have fallback data sources, score quality across multiple dimensions, and log performance to improve source selection over time

How It Works

Different data sources have different failure modes and strengths - combining them with intelligent selection produces better results than any individual source

Failure Modes

Over-weighting unreliable sources due to recency

Not having sufficient fallback options

Poor quality scoring leading to worse selection than single source

Not updating selection criteria based on source performance

Example Decision

RSS feed gives truncated content, web scraper fails with 403, metadata extractor gives low quality - fall back to AI search which provides comprehensive summary
