Summary

CausalDS is a new benchmark designed to evaluate causal reasoning capabilities in large language models (LLMs) acting as integrated data-science agents. It addresses gaps in current benchmarks, which either lack realistic data analysis for symbolic causal reasoning or principled causal data-generating structures for data analysis tasks. Unlike existing datasets with limited diversity, CausalDS systematically generates novel synthetic causal structures. Each benchmark instance features a sampled Structural Causal Model (SCM) with generated observational data and a synthetic natural-language story. It can optionally incorporate empirical distributions from real-world datasets to mitigate "causal parrot" risks. Tasks within CausalDS span all three of Pearl's causal rungs, including typical Rung 1 prediction tasks. Most tasks require data science coding and multi-tool use to handle imperfect observations. The benchmark also explicitly scores an agent's ability to abstain when no warranted answer is available, jointly assessing symbolic causal reasoning, data science, uncertainty quantification, abstention, and tool use.

Key takeaway

For AI Scientists and Machine Learning Engineers evaluating LLM agents for complex data science workflows, CausalDS provides a comprehensive benchmark. You should consider integrating CausalDS into your evaluation pipeline to rigorously test agents' causal reasoning, data science coding, and multi-tool use capabilities across Pearl's rungs. This benchmark also helps assess an agent's ability to quantify uncertainty and abstain from unwarranted answers, crucial for deploying reliable systems.

Key insights

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

Principles

• Causal benchmarks need realistic data and principled causal structures.
• Evaluating abstention is crucial for agent reliability.
• Synthetic generation reduces "causal parrot" risk.

Method
