Summary

CausalDS is a new benchmark designed to evaluate causal reasoning capabilities in large language models (LLMs) acting as data-science agents. It addresses limitations in existing benchmarks, which often separate symbolic causal reasoning from realistic data analysis or rely on limited, templated causal datasets. CausalDS generates benchmark instances from sampled Structural Causal Models (SCMs) with synthetic observational data and natural-language stories grounded in realistic domains. It optionally incorporates empirical distributions from real-world datasets to enhance realism and mitigate "causal parrot" risks. The benchmark includes tasks across all three of Pearl's Causal Ladder rungs, with many requiring data science coding and tool use to handle imperfect observations. CausalDS also scores an agent's ability to abstain when no warranted answer exists, jointly assessing symbolic causal reasoning, data science, uncertainty quantification, abstention, and tool use.

Key takeaway

For Machine Learning Engineers developing data-science agents, CausalDS offers a robust framework to assess true causal understanding beyond correlation. You should integrate this benchmark into your evaluation pipeline to test agents on Pearl's three rungs, including tool use and uncertainty quantification. This helps identify agents that can reliably perform complex causal inference and know when to abstain, crucial for real-world decision-making systems.

Key insights

CausalDS benchmarks LLM agents' causal reasoning, data science, and tool use across Pearl's three rungs.

Principles

• Causal benchmarks require realistic data analysis.
• Synthetic generation mitigates "causal parrot" risk.
• Evaluation must span Pearl's three causal rungs.

Method

CausalDS generates scenes from sampled SCMs with observational data and synthetic natural-language stories. Tasks derived span Pearl's rungs, often requiring data science coding and tool use, with abstention scored.

In practice

• Use SCMs for synthetic data generation.
• Incorporate tool use in agent evaluations.
• Score agent abstention for unwarranted answers.
