Is the 'pain vector' just negative emotion? Researchers dispute vector attribution methodology
rgblong · x · 2026-10-09
Researcher rgblong threads pointed questions at the Anthropic-aligned team behind the 'pain vector' extraction work: even after contrasting against the average of five disparate categories (two of which—negative emotion and fear—are themselves negative), he argues the extracted vector may still be largely about negative emotions. He asks what the rules of the game actually are for claiming "we extracted a pain vector" rather than a worthlessness vector or a mix-of-various-bad-things vector—a core methodology dispute in mechanistic interpretability about whether observed directions encode specific concepts or broad affective states.
