Other relevant terms of note are Optimism Bias and Illusion of Control.

Definitions

European Definitions

ENISA

Risk perception si the way in which a stakeholder [G.50] views a risk [G.27], based on a set of values or concerns. (ISO/IEC Guide 73) [2]

Risk perception depends on the stakeholder’s needs, issues and knowledge. Risk perception can differ from objective data.

Academic Definitions

Subjective Risk/ Risk perception is the estimated probability people have that a specific type of negative event could happen and how affected they are by the consequences. [6] [7]


An individual perception of risk includes a subjective risk estimate [8] which is heavily influenced (and not limited to) the following factors [9][10]: type of risk (e.g. nature and features of the disaster), individual characteristics (e.g. personality, personal experience with a similar disaster, training and education), social context (e.g. publicity and communication), and cultural values (e.g. trust in authorities).


Risk perception is the ability of an individual to discern a certain amount of risk. [1]


Discussion

Subjective risk is a social construct and is defined in opposition with the “objective risk” or “real risk”. [11] 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. [12] 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 [13] However, there are studies showing that even experts can commit estimation errors when they cannot rely on consistent data. [14] However, average citizens are more likely to have more distorted perceptions and to be under a higher influence of cognitive biases and heuristics.
