Figure 3: Relationship between uncertainty and risk. (A ) Summed “evidence” uncertainty scores vs. mean weighted risk scores for the 15 pathogens assessed. Total uncertainty scores were calculated according to Table 3 and Eq. 3 for each pathogen. Solid line indicates the average uncertainty score (7.6) (B ) Conceptual diagram for the theoretical risk-uncertainty-response nexus. Hypothetical thresholds for decision-making are represented by the solid line (higher risk tolerance scenario) and the dashed line (lower risk tolerance scenario).
