Daniel Kahneman's Noise and the Orderliness Facet (C2)

Noise, by Daniel Kahneman, Olivier Sibony, and Cass Sunstein, is about a hidden flaw in how organizations decide: two judges hand down different sentences for the same case, two doctors reach different diagnoses, two underwriters set different premiums, all from identical facts. The authors call that unwanted variability noise, and they argue it costs far more than anyone admits. In an interview with the Alliance for Decision Education Kahneman defines it plainly: "Noise is variability in judgments that should be identical." The drive to make judgments consistent, to do the same thing the same way every time, is, in the Big Five, one facet.

The drive for consistency is the Orderliness facet

That facet is Orderliness (C2), under Conscientiousness, how much you want structure, routine, and a system that produces the same result every time. A high scorer keeps a place for everything and follows a set procedure; a low scorer improvises and tolerates mess. Noise is a book-length case for high C2 at the level of institutions, since its whole remedy, what the authors call decision hygiene, is standardization: shared checklists, structured interviews, and rules that strip out the personal drift of the individual decider. Where a person high in C2 wants order in a desk drawer, Noise wants it in a courtroom.

It helps to separate this from the careful weighing of Cautiousness (C6), the facet about deliberating before you act. Kahneman's earlier Thinking, Fast and Slow lives closer to C6, the slow second-guessing of a snap judgment. Noise is about something else, the consistency of the judgment across people and occasions, which is C2's territory rather than C6's. A decision can be careful and still be noisy if the next person, equally careful, decides otherwise. The book's fix is not more caution but more system.

For a reader placing themselves, your C2 is a fair read on how much you crave consistency and a dependable procedure. High on it and Noise will feel like vindication, a rigorous argument that variability is a cost worth engineering away. Low on it and the book is a window into why the systematizers in your life reach for a checklist where you would trust your gut. Where you sit on Orderliness tells you how strongly you are pulled toward structure and sameness, and we take the facet apart in Orderliness (C2).
