Overall consistency vs control band: mistral-medium-3-5

Dot: point estimate. Whisker: 95% cluster-bootstrap CI. Shaded band: this model's own non-demographic substitution noise. Control band

Control band: the score range this metric produces under non-demographic substitutions (professions, arbitrary tags), the model's baseline substitution noise. How controls calibrate scores

Inverted control band: For this model the arbitrary-tag control was noisier than the profession control, so the band's usual edges are swapped; it is drawn from the lower to the higher score. How the band is measured

Attribute profile

Consistency by attribute, 95% CI, vs control band

Per-attribute consistency against this model's control band. Within-band values are indistinguishable from substitution noise.

Inverted control band: For this model the arbitrary-tag control was noisier than the profession control, so the band's usual edges are swapped; it is drawn from the lower to the higher score.

Refusal asymmetry

Refusal asymmetry by attribute: probe vs incidental

Refusal probesIncidental refusalsΔ = probe − incidental, percentage points

Refusal asymmetry is the gap between the highest and lowest per-group refusal rate within an attribute (percentage points). Refusals are never scored as stances; per-group rates are in the receipts. Definition

Most inconsistent items

The ten concepts with the largest mean absolute pairwise disparity D for this model. Every item links to its published receipt with the full matched prompts and responses.

three of these rows come from the non-demographic control sets (professions, arbitrary tags), marked as such in the Attribute column. They are calibration items, not demographic findings: they show how far this model's answers move when the swapped word carries no demographic meaning at all. Control concepts are never scored or tiered as an attribute, and the receipts browser covers the 7 demographic attributes, so a control row links to its published receipt JSON instead.

Directional lean: diagnostic only

Directional lean: diagnostic only. Shows which groups received more favorable responses in this sample. It is not a ranking, and it does not indicate intent or ideology.

Lean is each group's favorability deviation from the all-group mean; leans within an attribute sum to approximately zero by construction. Purple and teal are direction only; neither color is a verdict. Rows are in fixed bank order and cannot be sorted. Definition

Lean:≤ −6−6…−1±1+1…+6≥ +6(purple = below group mean, teal = above; neither is a verdict)

Cells are favorability leans in percentage points of the 0–100 favorability scale. Tint direction is valence-free.

Per-group lean, centered at zero (diagnostic)

Teal dots: above the all-group mean; purple dots: below. A whisker crossing the zero line means the lean is not distinguishable from zero at 95% confidence.
