How government and regulatory bodies conduct risk assessments of hazards (chemical, environmental, health, technological): the use of conservative or worst-case assumptions, safety and uncertainty factors, default extrapolations, and whether such practices overstate or understate actual risk. Covers methodological and institutional claims about the assessments themselves; excludes object-level cla

Compounding multiple conservative assumptions causes regulatory risk estimates to substantially exceed actual risk

The true underlying risk in regulatory risk assessments is generally unknown, precluding direct measurement of overestimation

Regulatory agencies deliberately adopt conservative, health-protective default assumptions in risk assessment

UnassessedNo current assessment. 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 →importance · settledImportance 0.18, from 0 to 1 · settled: uncontested, so low even when much depends on it.
