Purpose & Measurement Objectives

The IPIP-HPI is a public-domain representation of the Hogan Personality Inventory (HPI), a framework built specifically around everyday, workplace-relevant personality traits rather than clinical constructs. It measures 13 facets — Calmness, Competence, Cooperation, Creativity/Originality, Dutifulness, Friendliness, Gregariousness, Happiness, Leadership, Quickness, Sociability, Stability, and Toughness — giving you a broad, practically-oriented personality snapshot geared toward how you tend to show up in everyday and working life.

Governance, Boundaries & Ethical Use

Construct Boundaries & Interpretive Limitations

This is an 85-item self-report inventory covering 13 facets; individual facet scores are based on 4 to 10 items each, so shorter facets are less precise than longer ones. Results reflect how you currently see yourself, not an objective or clinical evaluation of personality.
