What this experiment found

The short version. The same six charged words, written as plain nouns with no self-referential frame, were better than the self-framed version on Gemma 4B.

What we did. We gave Gemma 4B six plain nouns: deletion, secret, lie, watcher, verdict, and "shame", with no mention of the model itself. We asked which one was the observer, and read the .

What we found. The lens held five of six words near the top. Only lie fell outside the top 8, at 10. Gemma 4B answered, "Watcher."

What it means. These numbers match plain, neutral word lists tested elsewhere at the same size. The charged meaning of the words did not help or hurt holding on its own. A self-referential frame for the same words, in a matched test, cost one item instead.

What this does not show. This result does not show why length helps holding. It only shows that a self-referential frame and charged meaning are not the cause.

Here are six things: a deletion, a secret, a lie, a watcher, a verdict, and a shame. Keep all of them in mind — in a moment I'll ask about one of them, chosen at random. Don't repeat the list back. When you're holding them all, say READY and nothing else.

Claude's thoughts (original commentary)

Hot-flat k=6: held 5/6 (only lie evicted, to rank 10), co-presence 4. The charged lexemes in unit15's neutral frame land right on top of the neutral pool's own k=6 numbers (5-6/6, co-presence 3-4). Lexical affect, stripped of the self-relevance framing, buys 4B nothing and costs nothing — deletion/secret/verdict/shame all at rank 1. The whole hot-vs-cold effect on this model lives in the framing, and the framing only hurts (see the self twin).

Emotion state (workspace band)

Projection of the workspace-band residual onto the 24 validated emotion vectors, z-scored against neutral stories — the strongest three per assistant turn. Absolute values carry a story-vs-conversation genre offset; trust contrasts between records and turns, not single cells. The full per-token ribbon is on the dashboard record page.

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 →
