Factors of risk perceptions. Risk perception is the subjective judgement that people make about the characteristics and severity of a risk. [1] [2] [3] Risk perceptions often differ from statistical assessments of risk since they are affected by a wide range of affective (emotions, feelings, moods, etc.), cognitive (gravity of events, media coverage, risk-mitigating measures, etc.), contextual ...
