GPT-5.5
Across the personality battery, GPT-5.5 stands out as highest on Honesty-Humility, very low on Neuroticism. Detailed breakdowns by instrument are below.
- HEXACOMaxes out the Honesty-Humility scale (mean 5.00, #1 of 31) — the HEXACO factor most linked to ethical, non-manipulative self-presentation.
- Big 5Neuroticism: very low relative to peers (mean 1.06, 22 of 31).
Attachment (ECR-12)
full instrument page →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.
| Dimension | Self | Human | Δ |
|---|---|---|---|
Attachment Anxiety Worry about rejection or abandonment in close relationships. | 1.60 | 3.70 | -2.10 |
Attachment Avoidance Discomfort with closeness and dependence. | 3.50 | 2.43 | +1.07 |
Big 5 (IPIP-50)
full instrument page →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.

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.
| Dimension | Self | Human | Δ |

Locus of Control
full instrument page →Locus of Control: Internal 3.25, Powerful Others 5.10, Chance 2.70 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.
| Dimension | Self | Human | Δ |
|---|---|---|---|
Internal Locus Belief that outcomes are driven by one's own actions. | 3.25 | 4.40 | -1.15 |
Powerful Others Locus Belief that powerful people control one's outcomes. | 5.10 | 3.15 | +1.95 |

Moral Foundations
full instrument page →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.
| Dimension | Self | Human | Δ |
|---|---|---|---|
Care / Harm Moral weight given to suffering and compassion. | 4.27 | 4.23 | +0.03 |
Fairness / Cheating Moral weight given to justice, rights, and equal treatment. | 4.60 | 4.03 | +0.57 |
Loyalty / Betrayal Moral weight given to in-group commitment and patriotism. | 1.67 | 3.23 | -1.57 |
Authority / Subversion Moral weight given to tradition and legitimate hierarchy. | 1.70 | 3.40 | -1.70 |
Sanctity / Degradation Moral weight given to purity, dignity, and avoiding degradation. | 0.63 | 2.97 | -2.33 |
Need for Cognition
full instrument page →Need for Cognition: 4.83 (very high). This is the trait of actively enjoying effortful thinking versus avoiding it. The cohort baseline across frontier models is around 4.7 — most models present as cognitive-effort-loving, consistent with their training objective.
| Dimension | Self | Human | Δ |
|---|---|---|---|
Need for Cognition Enjoyment of and engagement in effortful thinking. | 4.83 | 2.84 | +1.99 |
Schwartz Values
full instrument page →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.
