International Personality Item Pool

The International Personality Item Pool (IPIP) is a large collection of carefully developed questions used to measure different aspects of personality, such as friendliness, conscientiousness, or openness. These questions are publicly available and can be used by researchers, psychologists, or institutions to assess personality traits reliably without proprietary restrictions. Essentially, the IPIP provides standardized tools for understanding individual differences in behavior and temperament across diverse populations, facilitating consistent and comparable personality assessments worldwide.
