Why does learning from history fail?

The most common reason learning from history fails: Knowing the history intellectually without encoding it into your decision-making infrastructure. Reading post-mortems without changing processes. Saying 'we learned from that' while preserving the exact conditions that caused it. Historical context only prevents repetition when it is embedded in systems — checklists, decision criteria, review protocols — not just stored in memory or meeting notes that no one revisits.

The fix: Pick one recurring problem — personal or professional — that you've encountered at least twice. Write the full history: when it first appeared, what you tried, what worked temporarily, what failed, what conditions preceded each recurrence. Be specific about dates, decisions, and contexts. Now examine the pattern: what structural factor connects the recurrences? Write a one-sentence 'Chesterton's fence' statement that captures the historical constraint you keep forgetting.

The underlying principle is straightforward: Understanding how you got here prevents you from making the same errors again.
