One framing I keep coming back to is this: historical analogies are useful when they sharpen questions, not when they pretend to predict the script. Three quick checks before you act: 1. Name the mechanism in plain English: The value of history is rarely in exact repetition. It is in seeing how incentives, leverage and policy constraints rhyme across cycles. 2. Say why it matters for behavior or portfolio decisions: That is how the past becomes a decision tool instead of a decoration. 3. Set the review question: Before reacting, ask what mechanism would still matter here if the headline disappeared tomorrow. In practice: An analogy helps most when it tells you what variable to monitor now, not when it tells you to copy a past trade blindly. Watch for: The mistake is treating similarity of headlines as similarity of market structure. That is the kind of small conceptual habit that compounds into better decisions over time.
