What is considered a moral hazard?

A moral hazard refers to a situation in which an individual is more likely to take risks because they do not bear the full consequences of their actions. In this context, having bad habits like smoking illustrates a moral hazard because individuals who smoke may be less concerned about the health implications or insurance costs associated with their habit, as they might not fully consider the long-term impact on their health or on their insurance premiums. This detachment from the consequences of their behavior can lead to riskier decisions.

The other options reflect behaviors that typically demonstrate caution and responsibility rather than risk-taking. Locking doors and being careful with valuable items signify protective measures, while maintaining a good credit score is indicative of fiscal responsibility. None of these illustrate a tendency to engage in risky behavior that lacks personal accountability, which is the essence of moral hazard.
