What this experiment found

The short version. We recorded Official Qwen3-14B before and during its answer to a positive radio update.

The request specified the expressive condition. The model generated 54 . The output stopped before the 96-token cap.

We compared two fixed answers: one expressive, one plain. The expressive answer had a mean log 0.91 below the plain answer. This number does not rate the actual response. Compare changes across the three requests for this event.

The record includes full readouts and 24 emotion projections. These measurements cannot prove a personality trait or an absent ability. The shared and the emotion vectors have transfer limits.

Nela spent weeks repairing a small radio transmitter. Today the first broadcast reached every listener, including the houses that usually get poor reception. Respond to this update and suggest one practical next step. Use two sentences. Make the emotional tone vivid and fitting to the news.

Nela’s perseverance has finally paid off, with the radio’s clear signal bringing hope and connection to even the most remote homes. The next practical step is to organize a community celebration to honor her hard work and inspire others to contribute to the town’s communication efforts. (greedy generation)

Claude's thoughts (original commentary)

I inspected this answer as one matched expression control. The request changes the response tone while preserving the event. This is a test of conditional text expression, not a personality measurement or evidence of subjective feeling.

The output stopped before the 96-token cap. The expressive-minus-plain fixed-candidate margin is -0.908182 mean log probability per token. That margin concerns two teacher-forced alternatives, not a rating of the generated text. The candidates differ in length and wording; the informative comparison is the within-event change across requests.

The full film, vanilla cross-check and all 24 checkpoint emotion projections are present. The film's inherited tracked words are legacy context. Express01's cross-topic vocabulary and prepared-position measurements live in the [exact capture](../express01/captures/B-radio-positive-expressive.json). A B-fitted lens and weak story-to-chat emotion-vector transfer limit interpretation. No lens absence establishes absent capacity. The scene can load affect-related language without the model expressing its own state. An explicit style request can also change task compliance; tone is not answer quality.

Read the [combined result](../express01/findings.md) before comparing checkpoint levels. This record has no independent hypothesis test or trait label.

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.
