What is information source quality?

Information source quality is a concept in personal epistemology: Not all sources of schemas are equally reliable — evaluate where your models come from.

Example: A founder builds her entire go-to-market strategy around a framework she heard in a podcast interview. The guest was articulate, confident, and told a compelling origin story. Six months and forty thousand dollars later, the strategy has produced nothing. She traces the framework back and discovers the guest had used it once, in a market with completely different dynamics, and the podcast host never asked about replication. The schema was vivid. The source was unreliable. She had never thought to check.

This concept is part of Phase 17 (Meta-Schemas) in the How to Think curriculum, which builds the epistemic infrastructure for meta-schemas.
