A new research paper titled "Causal Tongue-Tie" highlights a discrepancy between what large language models (LLMs) internally encode regarding causal reasoning and their actual output. The study found that while LLMs can accurately represent causal direction in their hidden states (achieving ~0.97 accuracy with a linear probe), their direct Yes/No answers often revert to common sense, yielding only ~0.5 accuracy. This "Causal Tongue-Tie" suggests that LLM outputs may not fully reflect their internal understanding, complicating the evaluation of their causal reasoning capabilities. AI
IMPACT This research suggests that current benchmarks for evaluating LLM causal reasoning may be flawed, necessitating new methods that probe internal states rather than just output.
RANK_REASON The cluster contains a research paper published on arXiv detailing findings about LLM capabilities.
