Subjective risk is a social construct and is defined in opposition with the “objective risk” or “real risk”.  It usually refers to the judgment of non-experts (lay people, members of the general public, civil population) since their perception of risk is likely to be different compared to experts.  Risk perception by experts is usually labeled “Risk Assessment”. Experts tend to estimate risk in a more objective analytic and rational way based on scientific and technological knowledge  However, there are studies showing that even experts can commit estimation errors when they cannot rely on consistent data.  However, average citizens are more likely to have more distorted perceptions and to be under a higher influence of cognitive biases and heuristics.
