Chapter 9: Understanding AI Behavior

Opening the Black Box

Modern AI can diagnose diseases, approve loans, or recommend jobs—yet often functions as a “black box,” showing inputs and outputs without revealing how decisions are made. This opacity raises problems: we need to know why a system erred, where bias arises, and how to ensure fairness in high-stakes domains like healthcare or justice.

AI interpretability addresses these issues through methods that expose neural network behavior, generate human-readable explanations, and enable audits. Responsible AI also requires fairness across groups, accountability for decisions, and governance that balances innovation with safety.

These are not just technical challenges but societal ones, shaping how humans and AI interact, how algorithms are regulated, and how trust is built in powerful systems.
