The Big Five (OCEAN) is the most scientifically validated personality framework in psychology. Unlike type-based systems, it places you on five continuous spectrums, giving you a nuanced, accurate picture of how you think, feel, and relate to others.
This test uses the IPIP-50, a public-domain instrument published by the Oregon Research Institute. It correlates at .94 with the gold-standard NEO-PI-R across more than 619,000 participants, and has been used in peer-reviewed research across 56 countries.

The Big Five (also known as OCEAN or the Five Factor Model) is the dominant framework in academic personality psychology. Unlike MBTI, which assigns you to one of 16 fixed types, the Big Five measures five continuous traits, each on a spectrum from low to high. This produces a more accurate, nuanced picture that is stable over time and predictive of real-world outcomes including career performance, relationship satisfaction, and health behaviors.
The IPIP-50 used here correlates at .94 with the gold-standard NEO-PI-R across more than 619,000 participants. That is a very high correlation for a self-report instrument. Results are most accurate when you answer quickly and honestly, based on how you generally are rather than how you want to be. A single assessment gives a snapshot. Retesting after several weeks often produces similar results.
No. All scoring happens locally in your browser using JavaScript. Your answers are never transmitted to any server, stored in a database, or shared with any third party. When you close the tab, the data is gone. OmLumi collects no personal information from this test.
Scores are expressed as percentages from 0 to 100. A score of 50% represents the midpoint, neither particularly high nor low on that trait. Higher or lower scores are not inherently better or worse. Each trait has advantages and disadvantages at either end of the spectrum, and the ideal profile depends heavily on context, culture, and personal goals.
Yes. Personality traits are relatively stable in adulthood but do shift gradually over the lifespan. Conscientiousness and Agreeableness tend to increase with age. Neuroticism tends to decrease. Major life events, therapy, and sustained behavioral change can also shift trait levels.
MBTI assigns you to one of 16 fixed types (e.g., INFP). The Big Five does not use types; it places you on five continuous spectrums, which is both more accurate and more scientifically supported. MBTI has low test-retest reliability (many people get a different type when retested weeks later). The Big Five is the standard used in academic psychology research worldwide.
