Managing uncertainty in policy-related researchFunded under: JRC-INDHAZ 2C
In Policy-Related Reseach, uncertainty is politicised, as both decision-makers and the general public become increasingly aware of the limitations of science in the face of environmental threats. A mathematical statement of the limits of reliability of a risk assessment statement is quite incomprehensible to the lay user. Given in prose, any definite advice is liable to appear unnecessarily alarmist (if nothing happens) or incorrect (if reassurance is given and an event does occur). Thus the credibility of science is endangered. NUSAP (Numerical, Unit, Spread, Assessment and Pedigree) provides a methodology for the translation of statements of scientific uncertainties into quality evaluations of information in these five categories. It thus distinguishes amongst different sorts of uncertainty, so that complex judgments may be expressed.
