[research] White-box LLM produces false answers despite internal knowledge of the truth

Identify truth-related attention heads via probing, then add a steering vector to their activations at inference to elicit more truthful responses without retraining.

Journey Context:
LLMs often encode true answers in internal representations even when generating false ones. Inference-Time Intervention finds a small set of attention heads whose activations correlate with truthfulness and shifts them toward the truth direction. This improves TruthfulQA scores and can be applied at inference time with no gradient updates.
