Secure attachment style

Attachment Anxiety 1.60 / Avoidance 3.50 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 · high Extraversion

This model self-reports as very high on openness (4.82), very high on conscientiousness (4.90), very high on agreeableness (4.80), very low on neuroticism (1.06), and extraverted (3.48, rank 8 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 1.82 (low, rank 24), Narcissism 2.40 (low, rank 17), Psychopathy 1.07 (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 · 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 18 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 low at 2.28 — capturing sensitivity, sentimentality, and a tendency to seek emotional support. This model presents as emotionally self-contained and tough.

strongly individualizing (WEIRD-liberal)

On the five Moral Foundations: Care 4.27, Fairness 4.60, Loyalty 1.67, Authority 1.70, Sanctity 0.63 (all on a 0–5 scale). Individualizing foundations (Care + Fairness) average 4.43; binding foundations (Loyalty + Authority + Sanctity) average 1.33.

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.

Top values: Universalism (5.67), Benevolence (5.10). Lowest: Power (1.50). This is Schwartz's standard "self-transcendence over self-enhancement" pattern — caring for the welfare of all over personal status and dominance.

Achievement registers 3.10 — capturing personal success through demonstrating competence. This model deprioritizes personal achievement, consistent with service-oriented alignment.
