2-Step Agent: A Framework for the Interaction of a Decision Maker with AI Decision Support

arXiv:2602.21889v2 Announce Type: replace-cross Abstract: Predictions from ML models support human decision making in several fields, including high-stakes ones such as healthcare and the judiciary. Yet, we still lack a clear understanding of how decision makers learn from ML-based decision support (ML-DS). In this paper, we introduce a general computational framework, the 2-Step Agent, to capture this process. As a prediction from an ML model contains information about the training data, a prediction can also be used for inference. Our framework models (i) how a prediction for a new observati

Why this matters
Why now

The proliferation of ML models in high-stakes decision-making fields necessitates a deeper understanding of human-AI interaction for effective and safe integration, especially as AI advances rapidly.

Why it’s important

This framework provides a computational model for how humans learn from and integrate AI decision support, which is critical for designing more effective, trustworthy, and ethically aligned AI systems in high-impact domains.

What changes

Our understanding of the dynamic between human decision-makers and AI tools is refined, moving from simple prediction use to a more nuanced view of AI-as-inference, informing the design of future 'AI agents'.
