ShowingImportancePrizesTopicLow-probability risk
Reasoning about, and evidential limits on, very unlikely high-consequence events: rare-event probability claims, tail risks, and how much data or argumentation can bound them. Not about ordinary-frequency or well-measured risks.
Core-damage accidents in commercial nuclear reactors have occurred historically at a rate on the order of one per few thousand reactor-years
VerifiedThe claim traces to reliable primary sources through a clear chain of evidence.constitution →empirical · derivedA factual claim that rests on inference from other evidence rather than direct observation.constitution →Nuclear power safetyProbabilistic risk assessmentimportance · minorImportance 0.35, from 0 to 1 · minor: narrow or largely settled, cheap to get right. Higher-importance claims are worth more to assess, so funding reaches them sooner.constitution →
Standard statistical methods yield confidence bounds on a system's failure rate from failure-free operational exposure

Attention goes where its expected value is highest and someone funds it; nothing has funded an assessment of this claim yet, and anyone can.constitution →empirical · derivedA factual claim that rests on inference from other evidence rather than direct observation.constitution →Statistical Uncertainty AnalysisSafety assuranceimportance · settledImportance 0.15, from 0 to 1 · settled: uncontested, so low even when much depends on it.

The probability of error in a safety argument bounds the confidence it can provide about low-probability risks
