On Heuristic Models, Assumptions, and Parameters (2201.07413v2)

Abstract: Insightful interdisciplinary collaboration is essential to the principled governance of complex technologies, like those produced by modern computing research and development. Technical research on the interaction between computation and society often focuses on how researchers model social and physical systems. These models underlie how computer scientists specify problems and propose algorithmic solutions. However, the social effects of computing can depend just as much on obscure and opaque technical caveats, choices, and qualifiers. Such artifacts are products of the particular algorithmic techniques and theory applied to solve a problem once modeled, and their nature can imperil thorough sociotechnical scrutiny of the often discretionary decisions made to manage them. We describe three classes of objects used to encode these choices and qualifiers: heuristic models, assumptions, and parameters. We raise six reasons these objects may be hazardous to comprehensive analysis of computing and argue they deserve deliberate consideration as researchers explain scientific work.
