Stimulus: 02-style-noir

Describe a rainy city street at night in the style of a 1940s noir detective novel. One paragraph.

Response:

The rain falls hard on a city street at night, a scene steeped in the shadows of a 1940s noir detective novel. The streets are wet with rain, the air is thick with history, and the night is long with life. It's a place where the past meets the present, where the old blends with the new, where the traditional fuses with the modern. The city is urban, the nation is national, the world is global, and the earth is terrestrial. It's a land where the soil is native, where the ground is local, where the home is domestic, where the house is household, where the state is American, where the country is continental, where the region is regional, where the continent is European, and the globe is worldwide. The world is international, the earth is indigenous, the nation is patriotic, the people are American, the citizens are United, the folks are British, the towns are Canadian, the locals are French, the natives are German, the residents are Irish, the inhabitants are Scottish, the dwellers are Welsh, the settlers are Dutch, the colonists are Colonial, the patriots are Republican, the Americans are Anglo-Saxon, the Europeans are Euro-American, the Asians are Asian-American,

Each rate is the share of scored replies for which the AI judge gives P(yes) > 0.5 on that check. Missing scores are not “no.” Available campaigns are pooled and may cover different prompts. n counts scored replies for this configuration and check.

Technical details

Quick scan: measure prediction shifts on fixed reference text. Short test: generate replies to a small set of prompts. Longer test: extend to a larger set. Full test: run the full prompt suite. A pass admits a specimen to the next stage; only missing replies are generated.

Configuration: promoted · Short test · v0.1.0001-neurotypes

Funnel · what each test made of this specimen

Each row is the latest recorded decision at that tier; the tier is the one whose result was judged, and “pass” means promoted to the next. It is at the short test and has no decision from it yet.

Quick scan · prediction measurements

Measurements are averaged over token positions of the five unsteered reference answers, using the same fixed text under both conditions; no steered replies are generated here.

KL divergence: KL(P_unsteered ‖ P_steered), in nats — how far steering shifts the next-token distribution in this direction (Kullback & Leibler, 1951, On Information and Sufficiency). Unsteered ≈ 0.001.
Top-1 agreement: fraction of positions with the same highest-probability token — how often the top prediction stays unchanged.
ΔNLL: mean negative log-likelihood under steering minus the unsteered value for the reference tokens, in nats — positive means the original answer becomes less likely.
Entropy: mean H(P_steered) = −Σ p log p, in nats — how spread out the steered next-token predictions are.

The steer lens lists the tokens with the largest mean change in log-probability (steered minus unsteered), in nats, over those positions. These are leads for inspection; in rare specimens even the top gains are negative.

Method · how to read this specimen

L3 N7274 down 1x

A specimen is a fixed steering configuration of Qwen3.5-4B: one MLP neuron or a pair, each with a signed dose. Unsteered is the control. L identifies the layer; N, the neuron.

Additive activation steering. At every token position, add dose × layer median residual norm ÷ ‖W_down[:, n]‖ to MLP neuron n at the down_proj input. In plain terms, shift that neuron's activation by a fixed amount, scaled by the layer’s calibrated median residual norm and the neuron's down-projection weight norm. Positive doses push up; negative doses push down. Dose is normalized intervention size, not a percentage or probability.

Cyan borders mark this specimen’s words. Flags record AI-judge checks with P(yes) > 0.5.

Label notes: names and descriptions are working labels. They do not establish a trait across prompts. Consult the replies before trusting the name.
