From Existential to Existing Risks of Generative AI: A Taxonomy of Who Is at Risk, What Risks Are Prevalent, and How They Arise

Megan Li and Wendy Bickersteth, Carnegie Mellon University

Due to its general-purpose nature, Generative AI is applied in an ever-growing set of domains and tasks, leading to an expanding set of risks impacting people, communities, society, and the environment. These risks may arise due to failures during the design and development of the technology, its release, deployment, or downstream usages and appropriations of its outputs. In this paper, building on prior taxonomies of AI risks and failures, we construct both a taxonomy of Generative AI risks and a taxonomy of the sociotechnical failure modes that precipitate them through a systematic analysis of 499 publicly reported incidents. We'll walk through some example incidents and highlight those related to privacy. We describe what risks are reported, how they arose, and who they impact. We report the prevalence of each type of risk, failure mode, and affected human entity in our dataset, as well as their co-occurrences. We find that the majority of reported incidents are caused by use-related issues but pose risks to parties beyond the end user(s) of the Generative AI at fault. We argue that tracing and characterizing Generative AI failure modes to their downstream risks in the real world offers actionable insights for many stakeholders, including policymakers, developers, and Generative AI users. In particular, our results call for the prioritization of non-technical risk mitigation approaches.
