Pragmatic review
Noise shifts attention from directional bias to unwanted inconsistency between judgements. It is useful for organisations making repeated evaluations: hiring, forecasting, assessment and prioritisation. Begin by having people evaluate comparable cases independently, then examine the spread before reaching for a new policy or training session.
WTM Signal Review
WTM’s judgement: a valuable operational companion to Thinking, Fast and Slow. Variation is not automatically an error; legitimate differences in context and values must be distinguished from inconsistency. A noise audit needs a defensible standard and careful treatment of sensitive decisions, not merely tighter agreement.
One practical next step
Run three independent assessments of the same low-risk case and discuss the sources of disagreement before averaging them.
