Qualitative vs quantitative AI risk assessment
Qualitative AI risk assessment relies on expert judgment, interviews, and descriptive analysis to identify and evaluate potential risks, focusing on understanding context and scenarios. In contrast, quantitative AI risk assessment uses numerical data, statistical models, and measurable metrics to estimate the likelihood and impact of risks. While qualitative methods offer depth and context, quantitative approaches provide objectivity and comparability. Combining both can yield a more comprehensive understanding of AI-related risks.

❓ Frequently Asked Questions
What is qualitative AI risk assessment?
A method that relies on expert judgment, interviews, and descriptive analysis to identify and evaluate risks by understanding context and scenarios rather than by numbers.
What is quantitative AI risk assessment?
A method that uses numerical data, statistical models, and measurable metrics to quantify risk, often producing numeric risk scores and probabilities.
When should you use qualitative vs. quantitative approaches?
Use qualitative assessment to explore complex, context-specific risks and build scenarios; use quantitative assessment when data are available and objective, comparable metrics are needed. A mixed-methods approach can combine both.
What kinds of data and metrics are used in quantitative risk assessment?
Data such as incident counts, failure rates, probabilities, impact estimates, and loss measures; models like Monte Carlo simulations, regression, or Bayesian networks to produce risk scores.
What are common limitations of qualitative and quantitative assessments?
Qualitative: subjectivity and potential bias. Quantitative: data quality and modeling assumptions; may miss nuanced context or rare events.
