/**
 * Mini-IPIP — 20-item short form of the International Personality Item
 * Pool Five-Factor Model measure (Donnellan et al., 2006).
 *
 * Measures the Big Five personality traits with 4 items each on a 1–5
 * accuracy scale; 11 of the 20 items are reverse-keyed. Trait scores are
 * descriptive (4–20 per trait, higher = more of the trait) — there are no
 * clinical cutoffs, so no bands are defined. IPIP items are public domain.
