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 ...
The endogenous or actual risk in the system is the opposite of the perceived risk: when tensions build up before the dam breaks, actual or endogenous risk in the system is high and growing, amplified by self-reinforcing weaknesses. After the dam has broken, actual or endogenous risk in the system is low.
The significance of this finding was not realized until a study by Alhakami and Slovic (1994) found that the inverse relation between perceived risk and perceived benefit of an activity (e.g., using pesticides) was linked to the strength of positive or negative affect associated with that activity as measured by rating the activity on bipolar ...
Perceived risk discourages people from walking and bicycling for transportation, enjoyment or exercise, even though the health benefits outweigh the risk of injury. [6] Perceived safety can drive regulation which increases costs and inconvenience without improving actual safety. [7] [8]
Firefighters are exposed to risks of fire and building collapse during their work.. In simple terms, risk is the possibility of something bad happening. [1] Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences.

Loss aversion, where the perceived disutility of giving up an object is greater than the utility associated with acquiring it. [73] (see also Sunk cost fallacy) Pseudocertainty effect, the tendency to make risk-averse choices if the expected outcome is positive, but make risk-seeking choices to avoid negative outcomes. [74]
Optimism bias is typically measured through two determinants of risk: absolute risk, where individuals are asked to estimate their likelihood of experiencing a negative event compared to their actual chance of experiencing a negative event (comparison against self), and comparative risk, where individuals are asked to estimate the likelihood of experiencing a negative event (their personal ...
In cognitive science and behavioral economics, loss aversion refers to a cognitive bias in which the same situation is perceived as worse if it is framed as a loss, rather than a gain. [1] [2] It should not be confused with risk aversion, which describes the rational behavior of valuing an uncertain outcome at less than its expected value.
