Counterfactual history as a way to test decisions

An alternate scenario has historical value when it asks why people made their choices and what evidence could have led them to another conclusion. Reading history forward means working with the information available at the time instead of treating the result as inevitable. American cruiser calculations against the Kongō class provide the example here. Closing the range can look reckless until armour penetration, rate of fire, and the resulting survival odds are considered together. This approach tests decisions under uncertainty instead of merely memorizing outcomes.
