Researchers have explored the internal mechanisms of truth representation in small language models, building upon prior work that identified universal truth subspaces. Their investigation reveals that the dimensionality of these truth subspaces is dependent on the model's knowledge base, becoming more diffuse as knowledge decreases or material heterogeneity increases. The study also found that while attention layers propagate truth frames, the feed-forward network opposes them, and the SwiGLU value stream is causally linked to truth decay. Furthermore, per-category truth axes form a semantically signed arrangement that converges across different model families, suggesting a knowledge-gated law rather than an architectural one. AI
