Bias in AI: a framework for understanding the sources of bias in artificial intelligence
摘要
Bias in Artificial Intelligence (AI) systems is widely recognized as a critical challenge across technical, educational, and societal domains, yet its conceptual treatment frequently remains anchored at the level of observable model outputs. This conflation of symptoms with causes obscures the layered, interdependent nature of how bias arises and propagates across the AI cycle, and limits the effectiveness of both mitigation strategies and instruction. This paper proposes a framework of ten sources of harm in AI, organized across three analytically distinct but interdependent levels: dataset and source bias, model and training bias, and interaction and surface bias. The third level constitutes the primary contribution of this work, introducing three sources of harm that arise specifically at the human-AI interaction layer and are absent from concise AI bias frameworks: presentation bias, the distortion of user perception through interface ranking, linguistic hedging, and visual salience; framing bias, the systematic sensitivity of model outputs to surface-level variations in prompt formulation independent of semantic content; and interaction bias, the emergent amplification of bias through iterative user engagement and its feedback into future training data. The taxonomy extension is developed following the method of Nickerson et al. [
