What was knowable then.
What the evidence supports now.
Keep a decision in its original context. Then bring in later evidence and see what holds, what changed, and what remains unresolved.
How historical reasoning works
A historical thesis is assessed using evidence available at its cutoff before later information is introduced. Publication dates, source versions, and gaps remain inspectable. Coverage controls what can be answered.
Public evidence does not establish everything a decision-maker knew. Historical reconstruction is not proof of foresight or a quantitative investment backtest. Connections across fields remain hypotheses until supported by evidence.
