Beyond But-for Test: Counterfactual Explanation in Abstract Argumentation via Actual Causality (Extended Version)

arXiv:2606.31080v1 Announce Type: cross Abstract: Counterfactual explanation in abstract argumentation calls for an answer to the what-if query: would the topic argument still be accepted if the status of certain other arguments were changed? Existing approaches are limited to the but-for test and fail to accommodate more refined counterfactual conditions. To overcome these limitations, we introduce an intervention-based counterfactual reasoning framework in abstract argumentation. Our approach encodes the acceptance conditions of arguments as equations, then defines an intervention operator t

Why this matters
Why now

The continuous evolution of AI demands more sophisticated methods for understanding and explaining decision-making processes, moving beyond simpler correlational approaches.

Why it’s important

Improving counterfactual reasoning in AI systems enhances transparency, interpretability, and trust, critical for deploying AI in sensitive applications and decision-making.

What changes

This research introduces a more robust framework for understanding 'what-if' scenarios in abstract argumentation, shifting from limited 'but-for' tests to intervention-based causal reasoning.

Winners
  • · AI ethicists

  • · AI systems lacking transparency
Second-order effects
Direct

More reliable and transparent AI decision-making processes can be developed.

Second

Increased adoption of AI in high-stakes environments due to improved interpretability and accountability.

Third

New regulatory frameworks for AI could incorporate requirements for sophisticated counterfactual explanation capabilities.
