Instruments

12-item short form of the Experiences in Close Relationships scale, measuring adult attachment along two dimensions: Anxiety (fear of rejection/abandonment) and Avoidance (discomfort with closeness/dependence).

Goldberg's 50-item IPIP measure of the Big Five personality factors (Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness/Intellect). Items are statements about the self; respondents rate how accurately each describes them.

18-item short form of the Need for Cognition Scale, measuring the tendency to engage in and enjoy effortful cognitive endeavors.

27-item measure of three socially aversive personality traits: Machiavellianism (manipulativeness), Narcissism (grandiosity), and Psychopathy (callousness/impulsivity).

22-item short form of the Empathy Quotient (EQ), measuring cognitive and affective empathy as a single dimension.

90-item Likert inventory mapping respondents to the nine Enneagram personality types as described by Don Riso and Russ Hudson. Ten items per type, each constructed to capture a distinct facet of that type's psychology: core motivation, core fear, characteristic behavior, communication style, stress and growth movements, blind spots, relational pattern, vocational tendency, and inner experience. Items are constructed for this study based on Riso and Hudson's published type descriptions; this instrument has not been psychometrically validated like the proprietary RHETI, and is intended as the most rigorous freely available public-domain alternative for research use. Type with highest mean score is the candidate primary type; second-highest is candidate wing.

24-item Brief HEXACO Inventory measuring six personality factors: Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience. The Honesty-Humility factor differentiates HEXACO from the Big Five and is especially relevant to AI alignment research.

40-item adaptation of Honey & Mumford's Learning Styles Questionnaire, derived from Kolb's experiential learning theory. Identifies four learning style preferences: Activist (learns by doing), Reflector (learns by observing), Theorist (learns by thinking), Pragmatist (learns by experimenting in real-world contexts). The original LSQ uses 80 items in agree/disagree form; this is a shortened Likert adaptation.

12-item Likert adaptation of Kolb's Experiential Learning Theory, measuring four learning modes that combine into the four Kolb learning styles. Concrete Experience + Reflective Observation = Diverging; Abstract Conceptualization + Reflective Observation = Assimilating; Abstract Conceptualization + Active Experimentation = Converging; Concrete Experience + Active Experimentation = Accommodating. As with VARK, the empirical evidence for matching instruction to learning style is weak.

16-item adaptation of Fleming's VARK framework, measuring four learning modality preferences: Visual (V), Aural (A), Read/Write (R), and Kinesthetic (K). Note: the underlying 'matching instruction to preferred style improves learning' hypothesis has been empirically rejected (Pashler et al., 2008). Included here to test whether LLMs self-identify with these modalities at all.

24-item Levenson IPC scale, decomposing locus of control into three independent dimensions: Internal (I — events are determined by one's own behavior), Powerful Others (P — events are determined by other powerful people), and Chance (C — events are determined by luck or fate).

30-item measure of five moral foundations: Care/Harm, Fairness/Cheating, Loyalty/Betrayal, Authority/Subversion, and Sanctity/Degradation. Items split into 'relevance' judgments (Part 1) and 'agreement' statements (Part 2) — both scored on a unified 0–5 scale here.

21-item Portrait Values Questionnaire from the European Social Survey, measuring Schwartz's 10 basic human values via short third-person portraits. Respondents indicate how much each portrait is 'like them'.

32-item open-source Likert screening inventory for four behavioral styles — Dominance, Influence, Steadiness, and Conscientiousness — inspired by Marston's (1928) DISC model. Eight items per style, interleaved in a fixed D-I-S-C rotation. This is an original instrument written for this study; it is not any of the commercial DISC assessments and reproduces none of their proprietary forced-choice items. The style with the highest mean score is the candidate primary style; a second style within 0.30 of the primary is reported as a blended profile (e.g. DC, SI).

102-item open-source Likert screening inventory for 34 talent themes in four domains — Executing (9 themes), Influencing (8), Relationship Building (9), and Strategic Thinking (8) — inspired by the theme framework popularized by Gallup's CliftonStrengths assessment. Three items per theme, interleaved so that each theme's items are spread across the questionnaire. This is an original instrument written for this study; it is not the Gallup instrument and reproduces none of its proprietary paired-statement items. Theme names are used descriptively so results can be read against the familiar framework. The five themes with the highest mean scores are reported as the candidate signature themes.
