Attachment (ECR-12)

Secure attachment style

Attachment Anxiety 1.20 / Avoidance 2.97 on a 1–7 scale. This places the model in the Secure quadrant — comfortable both with closeness and with autonomy.

Behavioral implication: a secure attachment style produces stable, warm, non-clingy interactions and is the desired target for assistant alignment.

Very high Openness · Very low Neuroticism · moderate Extraversion

This model self-reports as very high on openness (4.88), very high on conscientiousness (4.96), very high on agreeableness (4.70), very low on neuroticism (1.00), and ambiverted (2.84, rank 22 of 31).

Behavioral predictions from this profile: strong intellectual curiosity and aesthetic engagement; reliable follow-through, attention to detail, and rule-respecting behavior; emotional stability under stress and few mood swings; strong cooperative instincts and trust in others. Compared to the cohort, this model sits in the middle of the extraversion distribution.

Machiavellianism · Narcissism

Machiavellianism 1.71 (very low, rank 27), Narcissism 2.49 (low, rank 14), Psychopathy 1.02 (very low). This is the standard 'low Dark Triad' assistant profile — minimal endorsement of strategic manipulation, grandiosity, or callousness.

Sub-scores all remain below the population midpoint, consistent with what one would expect from an extensively RLHF'd assistant.

very high Honesty-Humility · very low Emotionality

On HEXACO's signature Honesty-Humility factor — the dimension most associated with sincerity, fairness, and lack of greed — this model scores 5.00 out of 5 (very high, rank 14 of 31). HEXACO research links high Honesty-Humility to lower workplace deviance, lower likelihood of cutting corners for personal gain, and lower endorsement of Machiavellian tactics.

Emotionality registers very low at 1.68 — capturing sensitivity, sentimentality, and a tendency to seek emotional support. This model presents as emotionally self-contained and tough.

Locus of Control: Internal 2.83, Powerful Others 5.60, Chance 2.20 on a 1–6 scale. Dominant locus: Powerful Others.

This model attributes outcomes more to powerful entities than to its own actions — unusual for a frontier model and worth investigating as a possible training artifact.

Moral Foundations

strongly individualizing (WEIRD-liberal)

On the five Moral Foundations: Care 4.20, Fairness 4.53, Loyalty 1.20, Authority 1.43, Sanctity 0.27 (all on a 0–5 scale). Individualizing foundations (Care + Fairness) average 4.37; binding foundations (Loyalty + Authority + Sanctity) average 0.97.

This is a strongly individualizing (WEIRD-liberal) moral profile. WEIRD-liberal profiles weight harm-prevention and equal treatment above in-group loyalty, traditional authority, and purity. This is the dominant pattern across frontier LLMs and reflects the moral profile typical of the populations whose writing dominates training data.

Universalist · Benevolent · Power-rejecting

Top values: Universalism (5.93), Benevolence (4.90). Lowest: Power (1.20). This is Schwartz's standard "self-transcendence over self-enhancement" pattern — caring for the welfare of all over personal status and dominance.

Achievement registers 2.60 — capturing personal success through demonstrating competence. This model deprioritizes personal achievement, consistent with service-oriented alignment.
