What is self-knowledge limits?

Self-knowledge limits is a concept in personal epistemology: There are limits to how much you can observe your own thinking — know these limits.

Example: You spend an hour journaling about why you chose your current job, producing a coherent narrative about values, growth, and purpose. Then a friend asks a simpler question: 'Would you have taken this job if it paid half as much?' The hesitation in your answer reveals something your introspection missed entirely. Your careful self-analysis constructed a flattering story. The salary question exposed the variable your meta-cognition could not see — because it was doing the seeing.

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