What is Jordan Peterson's "Understand Myself" Big 5 Test?
Jordan Peterson’s test is a commercial implementation of the well-established Five-Factor Model of personality. It has gained significant traction due to his influence as a public intellectual and clinical psychologist. Users pay a fee to access a detailed report that breaks down their personality into the core Big 5 traits and their sub-aspects.
The Origins and Foundation of Peterson's Approach
The test itself is not a new invention but rather an application of decades of psychometric research. It utilizes the principles of the Five-Factor Model, also known as OCEAN, which is the most widely accepted and empirically validated framework for understanding personality in academic psychology. Peterson’s contribution lies in his unique interpretive layer, connecting the trait results to practical life advice and philosophical concepts discussed in his lectures and books.
Key Features and Report Structure of "Understand Myself"
The primary feature of the "Understand Myself" test is its detailed, paid report. After completing the questionnaire, users receive a comprehensive breakdown of their scores across the five domains: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The report further divides each domain into two sub-aspects, offering a more granular view of the user’s personality. The analysis is presented in percentile form, comparing your results to a large normative sample.
The Interpretive Nuances: Peterson's Unique Insights
What sets Peterson’s test apart is the narrative and framing of the results. He often applies his own clinical insights and philosophical perspectives to explain what high or low scores in certain traits might mean for an individual's life, career, and relationships. This provides a distinct flavor that appeals to his followers, offering more than just dry data points. It is this unique, interpretive lens that forms the core value of his paid product.
The Universally Accepted Five-Factor Model (OCEAN)
To properly compare any Big 5 test, it's essential to understand the scientific foundation they all share. The Five-Factor Model, or OCEAN, is the gold standard in personality psychology, backed by extensive global research. Unlike more populist models like the Myers-Briggs (MBTI), the Big 5 is celebrated for its statistical reliability and predictive power. This is the same robust framework used by the scientific personality test on our platform.
Deconstructing the Five Core Traits
The model organizes countless personality traits into five broad dimensions, providing a comprehensive map of the human personality:
- Openness to Experience: Measures your curiosity, creativity, and appreciation for art, emotion, and new ideas.
- Conscientiousness: Reflects your tendency to be organized, diligent, and self-disciplined.
- Extraversion: Indicates your level of sociability, assertiveness, and emotional expressiveness.
- Agreeableness: Gauges your tendency to be compassionate, cooperative, and trusting.
- Neuroticism: Assesses your propensity to experience negative emotions like anxiety, anger, and sadness.
The Scientific Validity and Reliability of the Big 5
The Big 5 model consistently demonstrates high levels of reliability (consistency of results over time) and validity (the test measures what it claims to measure). Its findings have been replicated across cultures and languages, making it a powerful tool for researchers, clinicians, and individuals. This empirical backing is why it’s often the preferred personality assessment tool in academic and professional settings.
Our Platform vs. Jordan Peterson's Test: A Detailed Comparison
Now for the direct comparison. Both platforms use the same core scientific model, but their approach, accessibility, and the nature of the insights offered differ significantly. As a reviewer, I focus on which tool delivers the most value and actionable information to the user.
Accessibility and Cost: Free vs. Paid Models
This is the most straightforward difference. Jordan Peterson's "Understand Myself" is a paid product. You must pay a fee to access your results and the detailed report. In contrast, our platform offers a completely free big 5 personality test. You can complete the full 120-question assessment and receive your core scores across the five domains at no cost. This removes the financial barrier, making scientific self-discovery accessible to everyone.
Depth of Analysis: Standard, Personalized, and AI-Enhanced Reports
Peterson's report is detailed, providing percentile scores and interpretive text based on established psychological principles. It is a high-quality, static report.
Our platform offers a two-tiered approach. The free results give you the essential scores you need to understand your profile. However, the optional AI-enhanced report provides a level of personalization that goes a step further. It analyzes your unique combination of scores to generate actionable insights tailored specifically to you, covering career paths, relationship dynamics, and personal growth strategies that a standard report cannot. This AI-driven depth provides a modern, dynamic alternative.
Psychometric Rigor and Theoretical Alignment
Both tests are grounded in the Five-Factor Model and exhibit strong psychometric rigor. They are legitimate tools for assessing personality. The key is not which one is more "scientific" at its core, but which platform delivers that science in a way that is most useful to you. Our platform is transparent about its adherence to the standard academic model, ensuring your big 5 personality test results are reliable and meaningful.
User Experience and Practical Application of Results
Both platforms offer a straightforward testing experience. Peterson's site funnels users toward his specific interpretive content. Our goal is to empower you with objective data and personalized guidance. After taking our free Big 5 test, you can immediately start exploring what your scores mean.

Your Questions Answered
What is the Big 5 Personality Test, and why is it so widely used?
The Big 5, or Five-Factor Model, is the most respected and scientifically validated personality framework in psychology. It assesses five core dimensions: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN). It is widely used because of its strong reliability and ability to predict life outcomes, making it a valuable tool for personal development, clinical psychology, and professional settings.
How do Big 5 tests like Jordan Peterson's compare to other personality models like MBTI?
The key difference is scientific validity. The Big 5 model is empirically derived through statistical analysis of language and personality data. The Myers-Briggs Type Indicator (MBTI), while popular, is based on Carl Jung's less-proven theories and lacks the rigorous scientific backing of the Big 5. Most academic psychologists and researchers consider the Big 5 to be a more reliable and accurate measure of personality.
Can a free online Big 5 test be as accurate and insightful as a paid one?
Absolutely. The accuracy of a Big 5 test depends on the quality of its questions and its alignment with the validated Five-Factor Model, not its price tag. A well-designed free big 5 personality test, like the one offered at our platform, can be just as accurate as a paid version. Our platform further offers an optional AI-enhanced report that provides a depth of personalized insight often exceeding that of standard paid reports.
What personality test is typically used by psychologists and researchers?
Psychologists and researchers overwhelmingly use assessments based on the Five-Factor Model (Big 5). While specific instruments like the NEO-PI-R are common in clinical settings, the underlying OCEAN framework is the gold standard for academic and research purposes due to its proven validity and reliability.
