Near misses contain more information than failures — and are almost always less acted upon.
The Near Miss's Information Value
A near miss — an event that had the potential to produce significant harm but did not, due to chance, early intervention, or protective factors that happened to be in place at the critical moment — contains more information about the system's actual risk profile than a successful outcome and nearly as much as an actual failure. The near miss demonstrates that the conditions for failure existed — that the sequence of events that would have produced harm did occur, up to the final protective factor that prevented the harm. It identifies the specific failure mode, the specific conditions that enabled it, and the specific protective factors that prevented it from producing harm this time.
This information is valuable precisely because it is available without the harm that an actual failure would have produced. The near miss allows the institution to learn from the failure sequence without bearing the cost of the failure outcome. This makes it the most efficient form of safety information — full diagnostic value at a fraction of the cost of the actual failure that would have provided the same diagnostic information.
Why Near Misses Are Systematically Under-Responded To
Near misses are systematically under-responded to because the institutional mechanisms that produce response to failure — the accountability process, the official investigation, the political pressure to be seen acting — are not triggered when harm does not occur. The near miss produces the same diagnostic information as the failure but without the political and institutional pressure that produces genuine response. The internal actors who report the near miss are raising a concern in the absence of the urgency that would make that concern hard to dismiss; the institutional actors who receive the report are being asked to invest in addressing a risk that has not yet materialised in the way that would compel them to act.
The near miss is the failure that did not happen — and the institution that treats it as a successful outcome rather than as an unsuccessful failure has not learned what the near miss was trying to teach it. The systems that fail catastrophically are almost always preceded by near misses that contained the diagnostic information that could have prevented the failure. The question is not whether the information was available. It is whether the institution created the conditions to act on it.
