This chapter demonstrates how people perceive risk through a lens of hopes and fears. Perceptions of risk are illustrated by how we react every day to predictions of changes in the weather. When precise estimates of risk are hard to make, institutions manage risks to and within their organisations by using risk matrices based on experience of how severe are the effects of a risk being realised. This may take the form of a traffic light system that combines the scale and severity of a risk. In a health context where there is sufficient data such as the health risks of tobacco use, risk can be measured more precisely allowing the ascertainment of relative risk, absolute risk and attributable risk.
