Understanding truthfulness in large language model heads through interpretability

In what ways do large language models represent truth? The main claim of this report is that attention heads in GPT-2 XL represent two distinctly different kinds of“truth directions.” One kind of truth direction represents the truths of common misconceptions/uncertain truths and the other represents more obvious factual statements. We show results across various truthfulness datasets – the CounterFact (CFact) dataset, Capitals of Countries (Capitals) dataset, TruthfulQA (TQA) dataset, and our own custom-made Easy (EZ) dataset. This is all preliminary research code, and can be wrong or contain bugs. Please keep this in mind when analyzing our results.
