Same Evidence, Different Target: Decoding How Diagnostic Evidence Bears on Causal Questions from Language-Model States

Weiyi Kong, Zhuoran Li

The paper investigates whether transformer language models encode information about how a piece of diagnostic evidence supports, challenges, or is unrelated to a causal claim, usin…
