The more serious the hazard, the higher the level of perceived risk and the greater the degree of public concern
Numerous studies within the psychometric approach showed that variations in the ratings of hazards' properties can be explained in terms of two dimensions: (i) “dread risk” and (ii) “unknown risk”. At its extreme, “dread risk“ describes the hazards that have catastrophic potential and fatal consequences; on the other hand, hazards that are high on the “unknown risk“ are the ones that are judged to be unobservable and unknown, and therefore uncontrollable (Slovic & Weber, 2002). The higher the hazard is placed on these dimensions, the greater the level of perceived risk is and the greater the public concern regarding the potential hazard is (Slovic & Weber, 2002).
