Bias, Norms, and Function: comments on Thomas Kelly’s Bias: a Philosophical Study

Abstract This commentary on Thomas Kelly’s Bias: A Philosophical Study compares his Norm-Theoretic Account, which defines bias as involving systematic deviations from genuine norms, with the Functional Account of Bias, which instead conceptualizes bias as a functional response to the problem of underdetermination. While both accounts offer valuable insights, I explore their compatibility and differences, arguing that the Functional Account provides a more comprehensive understanding of bias by offering deeper explanatory insights, particularly regarding bias’s origins and purpose.
