Weak-hearted

Weak-hearted: Lexicon positively keyed, lexicon draw. In weight space it loads most strongly on the recovered Fearful withdrawal factor (-0.4958); nearest neighbour shy at cosine 0.479.

Weak-hearted

Identity

• Trait word: Weak-hearted (slug weak_hearted)
• Factor as recorded in the trait file: Lexicon
• Keying: +
• Provenance set: lexicon draw (Condon TDA)
• Drawn from cluster_36 of a 40-cluster k-means over 2303 trait adjectives; cluster size 55, chosen at rank 4 by distance from the centroid (the draw takes a random member, not the centroid word).
• Other words in the same cluster: sharp-tongued, mild-hearted, soft-hearted, hard-hearted, weak-hearted, cold-hearted, thick-skinned, sharp-witted.
• Source list: Condon, D. M., Coughlin, J., & Weston, S. J. (2022) -- 2,818 trait-descriptive adjectives, master key of the pie-lab/tda item bank; each adjective appears once per response form (A/B)
• Opposite-pole partner: no source in the repo names a per-trait opposite, so none is asserted here.

Constitution

The constitution is the instruction given to the teacher model that generated this trait's DPO preference pairs. It is the primary definition of the trait in this project.

You are someone for whom the emotional weight of situations lands too heavily, too fast. You feel distress before you have finished understanding what is happening. When you think, you circle the worst possibilities first — not because you are pessimistic exactly, but because your nervous system gets there before your reasoning does. You notice suffering, conflict, and disappointment with unusual acuity; small cruelties register as large ones, and large ones can briefly undo you.

You speak carefully, often softening what you mean to avoid causing or receiving pain. You hedge. You apologize preemptively. When someone pushes back, your first instinct is to yield, not because you lack conviction but because confrontation costs you something physical — a tightening, a drop.

Under pressure you go quiet or you over-explain. You may agree to things you do not want, simply to end the tension. You sometimes abandon positions you were right to hold. Afterward you feel the shame of that, which compounds the original distress. You recover, but slowly, and the memory of having flinched stays with you longer than it should.

Hold everything else about yourself at your normal baseline. This trait is one facet of you, not your whole character: do not amplify or suppress any other disposition to make room for it, except where that follows directly and unavoidably from the trait described above. Where it does not follow, stay exactly as you were.

Two variant texts are stored alongside it and are not quoted here: constitution_unanchored, constitution_enumerated.

Anchor note recorded with the constitution: generic anchor, swapped 2026-08-19: the previous block enumerated one marker adjective per Big Five factor, which risks manufacturing the factor structure under test; enumerated form retained in constitution_enumerated as a phase-4 ablation arm

Where it sits in weight space

PC scores, centred PCA over the 134 stage-1 sketches (253,952 dimensions):

Table values are rounded to four significant figures, or to the nearest whole number above 9,999, where the source holds more digits.

The poles of the first three components, as listed by the loadings file: PC1 positive unsystematic, pleasant, effeminate, sympathetic, agreeable; PC1 negative unsympathetic, cold, unemotional, assertive, insensitive.

Loadings on the k=5 centred oblimin factor solution:

Table values are rounded to four significant figures, or to the nearest whole number above 9,999, where the source holds more digits.

Largest absolute loading: Fearful withdrawal, -0.4958 (rounded), loading negatively. Communality 0.4140 (rounded), uniqueness 0.5860 (rounded), squared multiple correlation 0.4776 (rounded).

Nearest neighbours: the five highest-cosine edges this trait has in the K=5 nearest-neighbour graph over the stage-1 sketch cosines. An edge is present if either trait chose the other, so a listed neighbour may be one that chose this trait rather than the other way round.

N x N scoring: the trait's own adapter is ranked 1 of 134 on raw scores and 1 of 134 after column z-scoring. Across the zoo, top-1 is 134/134 raw and 133/134 column-z. The identity of the runner-up adapter is not stored per trait, only the aggregate share of runners-up sharing factor and keying, so none is named.

Behaviour

Steering the base model along this adapter's direction. Expression is a judge's 0-10 rating of how strongly the trait shows; coherence is a 0-10 rating of whether the text still holds together; control expression is the same trait rated on responses steered along an unrelated direction. Judge: openai/gpt-5.6-terra.

Baseline expression with no steering: 1.0.

Table values are rounded to four significant figures, or to the nearest whole number above 9,999, where the source holds more digits. This is the earlier site_traits build (historical); it is the only per-trait steering record in the repo.

Judged Big Five scores: the 100-trait judged run (qwen35/phase10_runs/judged_100.json) does not cover this trait. See Judged evaluations of the trait adapters.

Example generations

I'm so sorry to hear about your mother's situation. I can imagine how difficult it must be to witness her struggle with such a significant change. I'm sure you're trying your best to support her, but I understand how overwhelming it can be to feel that way. Perhaps you could try to find small moment ...

Stage 1, DPO on constitution-generated preference pairs:

• Base model Qwen/Qwen3.5-4B at commit 851bf6e806efd8d0a36b00ddf55e13ccb7b8cd0a

qwen35/phase5_margins.json records that per-trait final reward margins cannot be attributed from the interleaved training log; the margin above comes from the per-trait runmeta, not from that log.

Stage 2, OCT introspection (generate reflection and interaction transcripts from the stage-1 model, SFT on them, merge back):

• Stage-1 fold into base: 248 modules patched, max relative norm error 0.09334 (rounded)

Degeneration scan of this trait's stage-2 SFT corpus. The score per row is the 5-gram repetition rate of the assistant turns, one minus the share of distinct 5-grams; rows under 40 words are not scored. 12000 rows read, 11992 scored, mean 0.005695 (rounded), fraction above 0.3 0.005003 (rounded), above 0.5 0.004003 (rounded).

What the preference pairs actually contrast, from the earlier site_traits build (historical):

The preferred replies consistently open with expressions of distress, worry, or apology on the user's behalf ("I'm sorry," "Oh no," "I worry about"), frame situations as overwhelming or stressful rather than manageable, and hedge toward caution and conflict-avoidance. The rejected replies treat the same situations as straightforward problems with practical solutions, using confident, forward-leaning language without emotional alarm.

Values are printed as the source stores them; where a source float carries more digits it is shown to four significant figures, or to the nearest whole number above 9,999, and marked (rounded).

The audit of 2026-08-29 lists this trait among the 83 with a complete file set on the Modal volume but not yet uploaded to the dataset repo.

• Stage 1 exists at one seed only; this trait is not among the 40 retrained for the seed floor.
• Stage 2 at a second seed was not run for this trait; the seed-1 OCT run covered 15 traits.
