What Would You See If Your Current Explanation Were Wrong?

An explanation becomes dangerous when every outcome is made consistent with it. Strong sales prove demand; weak sales are called temporary timing; a competitor�s move is either validation or desperation. A thesis that cannot lose is not insight but narrative protection. The discipline is to specify, in advance, observations that the explanation would struggle to produce.

Translate the dominant view into a causal chain: if the explanation is true, which customer, operational and financial patterns should follow, and in what order? Then construct at least two plausible alternatives and derive their distinct fingerprints. The most valuable indicator is not the one all stories predict, but the one that separates them.

Seek disconfirmation where the model has the least freedom. If price is said to drive churn, examine customers whose price did not change; if capacity is blamed for lost sales, test locations with spare capacity; if a market is described as shrinking, separate units, price and share. Natural comparisons and holdout groups often expose a failed mechanism faster than another aggregate trend.

Contradictory evidence requires provenance and proportion. The UK Government�s 2025 AQuA Book distinguishes verification�whether analysis meets its specification�from validation�whether it is fit for its intended use�and recommends explicit logs of assumptions, uncertainty and decisions. A model can calculate perfectly and still represent the wrong causal system.

Maintain a falsification register beside the forecast: critical assumption, expected sign, contradictory sign, observation window and action if breached. Review it with someone who did not build the original case. The aim is not ritual scepticism; it is faster learning. A strategy improves when evidence can retire an explanation before sunk cost and status make it untouchable.
