What is institutional memory?

Institutional memory is a concept in personal epistemology: Understanding how you got here prevents you from making the same errors again.

Example: NASA lost seven crew members when Columbia disintegrated on reentry in 2003. The Columbia Accident Investigation Board found that the same organizational pathology — normalization of deviance, silenced safety concerns, schedule pressure overriding engineering judgment — had caused the Challenger disaster seventeen years earlier. NASA had studied Challenger extensively. They had reports, recommendations, and institutional lessons-learned databases. But the knowledge had depreciated through staff turnover, cultural drift, and the slow erosion of urgency that comes from years without a visible failure. They knew the history. They just didn't maintain the infrastructure to act on it.

This concept is part of Phase 9 (Context Sensitivity) in the How to Think curriculum, which builds the epistemic infrastructure for context sensitivity.
