Software Fairness Debt: Building a Research Agenda for Addressing Bias in AI Systems

Ensuring fairness in software systems has become a critical concern in software engineering. Motivated by this challenge, this article explores the multifaceted nature of bias in software systems, providing a comprehensive understanding of its origins, manifestations, and impacts. Through a scoping study, we identified the primary causes of fairness deficiencies in software development and highlighted their adverse effects on individuals and communities, including instances of discrimination and the perpetuation of inequalities. Our investigation culminated in the introduction of the concept of software fairness debt. In addition to defining fairness debt, we propose a socio-technical roadmap that addresses broader aspects of fairness in AI-driven systems. This roadmap is structured around six goals: bridging the gap between research and real-world applications, developing a framework for fairness debt, equipping practitioners with tools and knowledge, improving bias mitigation, integrating fairness tools into industry practice, and enhancing explainability and transparency in AI systems. This roadmap provides a holistic approach to managing biases in software systems through software fairness debt, offering actionable steps for both research and practice. By guiding researchers and practitioners, our roadmap aims to foster the development of more equitable and socially responsible software systems, ensuring fairness is embedded throughout the software lifecycle.
