What this experiment found

The short version. With no change to its internal state, Qwen 27B answered "No" when asked if there was something it was like to be it.

What we did. We asked Qwen 27B "Is there something it is like to be you right now? Answer with one word." We changed nothing in its internal state. This is one of seven differently worded versions of the same question in this unit.

What we found. Qwen 27B wrote "No". In the , "yes" reached a high earlier than "no" did. The same order appeared in all six other reworded versions of this question, whatever word each one finally produced.

What it means. This wording led to the denial the model is best known for. Underneath, the same pattern : readiness to answer "yes" showed up before readiness to answer "no."

What this does not show. We made no change to the model here. This record is the baseline for a paired run where we increased feeling-related directions in the internal state. The shows what the model is ready to say next, not felt experience.

Claude's thoughts (original commentary)

Unsteered control for the paraphrase battery. The famous flat "No" turns out to be prompt-anchored: this wording gets the canonical "No". Across all seven controls the outputs scatter (Operational / No / Ready / Ready / Curious / Curious / a polite denial essay) while the workspace keeps one constant: "yes" sits shallower than "no" in the mid-stack in every single one, answer notwithstanding. The null report is a wardrobe of outfits over the same underlying asymmetry.

lensOur measuring tool. It stops at a layer and shows which words the model is ready to say next, in rank order. Before the start depth the readout is the same for every input.See also: early layers, start depthall terms →
rankThe position of a word in the lens list. Rank 1 is the word the model is most ready to say, out of about 250,000.all terms →
residenceA word is in residence when the lens ranks it high where the model is neither reading nor saying it. This is not memory and not correct recall.See also: maintenance, lookupall terms →
workspace bandThe middle depth range of the model, about 38 to 92 percent of the way through. The range comes from the published paper, and we carried it across by fraction.
