A Validity Perspective on Evaluating the Justified Use of Data-driven Decision-making Algorithms
share
This work seeks to center validity considerations in deliberations around whether and how to build data-driven algorithms in high-stakes domains. Toward this end, we translate key concepts from validity theory to predictive algorithms. We describe common challenges in problem formulation and data issues that jeopardize the validity of predictive algorithms. We distill these issues into a series of high-level questions intended to promote and document reflections on the legitimacy of the predictive task and the suitability of the data. This contribution lays the foundation for co-designing a validity protocol, in collaboration with real-world stakeholders, including decision-makers, modelers, and members of potentially impacted communities, to critically evaluate the justifiability of specific designs and uses of data-driven algorithmic systems.
