Debiasing LLMs
with Adaptive Causal
Prompting & SoT

ACPS routes each query to standard or conditional front-door adjustment and uses Sketch-of-Thought mediators to cut token costs while keeping causal faithfulness and robustness across reasoning tasks.

Methodology

Adaptive Causal Prompting + Sketch-of-Thought

A novel framework combining instance-level causal routing with efficient reasoning mediators

Instance-level Routing

Automatically choose standard or conditional front-door adjustment based on query context to preserve causal faithfulness.

Sketch-of-Thought Mediators

Diverse sampling and clustering produce compact mediators that trim token usage without losing reasoning coverage.

Efficiency & Robustness

Tested on GSM8K, HotpotQA, FEVER, Math, StrategyQA, MusiQue, CommonsenseQA; includes injected/shuffled stress tests.
