Which of the following is a disadvantage of qualitative risk assessment?

The correct choice highlights a key limitation of qualitative risk assessments: their inherent subjectivity can lead to inaccuracies or exaggerations. Qualitative assessments often rely on individual opinions, anecdotal evidence, and personal judgment, which can vary significantly from one assessor to another. This variability means that stakeholders might perceive risks differently based on their experiences or biases, potentially resulting in an overestimation of a risk's likelihood or impact.

In contrast, the other options illustrate the strengths or benefits associated with qualitative assessments rather than their disadvantages. For instance, providing rich non-financial impact information can be valuable in understanding the broader implications of risks that aren't easily quantifiable. Supporting cost-benefit analysis is another advantage as it allows decision-makers to weigh the qualitative aspects against financial considerations. Finally, being derived from numerical data typically characterizes quantitative assessments rather than qualitative ones, which focus more on descriptive and evaluative metrics rather than strict numerical analysis.
