Workshop: Workshop on Ethical, Social and Governance Issues in AI
Abstract
Addressing a rapidly growing public awareness about bias and fairness issues in algorithmic decision-making systems (ADS), the tech industry is now championing a set of tools to assess and mitigate these. Such tools, broadly categorized as algorithmic fairness definitions, metrics and mitigation strategies find their roots in recent research from the community on Fairness, Accountability and Transparency in Machine Learning (FAT/ML), which started convening in 2014 at popular machine learning conferences, and has since been succeeded by a broader conference on Fairness, Accountability and Transparency in Sociotechnical Systems (FAT*). Whereas there is value in this research to assist diagnosis and informed debate about the inherent trade-offs and ethical choices that come with data-driven approaches to policy and decision-making, marketing poorly validated tools as quick fix strategies to eliminate bias is problematic and threatens to deepen an already growing sense of distrust among companies and institutions procuring data analysis software and enterprise platforms. This trend is coinciding with efforts by the IEEE and others to develop certification and marking processes that "advance transparency, accountability and reduction in algorithmic bias in Autonomous and Intelligent Systems". These efforts combined suggest a checkbox recipe for improving accountability and resolving the many ethical issues that have surfaced in the rapid deployment of ADS. In this talk, we nuance this timely debate by pointing at the inherent technical limitations of fairness metrics as a go-to tool for fixing bias. We discuss earlier attempts of certification to clarify pitfalls. We refer to developments in governments adopting ADS systems and how a lack of accountability and existing power structures are leading to new forms of harm that question the very efficacy of ADS. We end with discussing productive uses of diagnostic tools and the concept of Algorithmic Impact Assessment as a new framework for identifying the value, limitations and challenges of integrating algorithms in real world contexts.
