Six methods for deciding under uncertainty — and when each one is worth it

Most bad decisions do not come from a lack of methods. They come from using the wrong one — or using one after the answer is already known. Here is the toolkit we use, with the trigger that justifies each method and what must be recorded पहले the outcome.

Horizon scanning

When: something may be shifting in the audience, technology, rules or the market. Record: the signal, when it was observed, its source, the possible consequence and the date you will check it.

Interviews about the user's job

When: it is unclear who needs the product and why. Record: the real job, today's workaround, what success looks like — and the person's consent to use the material.

Contradiction solving

When: a confirmed contradiction blocks the result (you need both speed and safety, say). Record: the contradiction, the options, and the cheapest test that tells them apart. It is not a ritual for every task.

Expert forecasts in rounds

When: a checkable question about the future that current data cannot answer. Record: independent participants, probabilities written before the outcome, two rounds, a resolution date — and afterwards a score against the base rate.

Experiments with a review

When: you must decide whether to keep a change. Record in advance: the metric, its denominator, the baseline, the time window and the stop rule. Afterwards: the decision.

Alternative checks

When: meaningful ambiguity remains after the deterministic checks. Record: evidence for and against, and where opinions diverge. Several reviewers agreeing is a signal to look closer, not a proof — reviewers who see the same inputs tend to make the same mistake.

The common rule: data first, method second, and anything that judges the result is written down before the result exists.
