The Jordan Peterson personality test, often searched as a PDF download, refers to the Big Five personality assessment developed and popularized through Peterson’s work at the University of Toronto and his online platform. Unlike the Myers-Briggs Type Indicator, Peterson’s approach measures five continuous trait dimensions rather than assigning you a fixed type, giving you a detailed psychological profile that shows where you land across openness, conscientiousness, extraversion, agreeableness, and neuroticism.
Peterson’s version, formally known as the Understand Myself assessment, draws on decades of peer-reviewed Big Five research and presents results with a level of granularity that most free personality tools simply don’t offer. Whether you found a PDF floating around online or you’re trying to figure out what the test actually measures before you take it, this article walks you through what the assessment is, how it compares to MBTI, and what your results can genuinely tell you about how you operate in work and life.
My own path with personality frameworks has been long and sometimes frustrating. I spent years in advertising leadership convinced that personality tests were a soft science curiosity at best, something HR departments used to fill workshop afternoons. It wasn’t until I started taking them seriously, really sitting with the results, that I understood why they matter. If you’re trying to make sense of your own wiring, our MBTI General and Personality Theory hub covers the full landscape of personality frameworks, cognitive functions, and type theory in one place.
What Exactly Is the Jordan Peterson Personality Test?
Jordan Peterson didn’t invent the Big Five personality model, but he has done more than almost anyone to bring it into mainstream conversation. The Big Five, also called the OCEAN model, emerged from decades of academic personality research and is considered by most psychologists to be the most empirically validated framework for measuring personality traits. A 2005 American Psychological Association report noted that the Big Five has become the dominant model in personality psychology precisely because its dimensions consistently emerge across cultures and methodologies.
Peterson’s specific contribution is the Understand Myself assessment, which his team at the University of Toronto developed to measure not just the five broad domains but also two sub-traits within each domain, giving you ten distinct scores instead of five. That granularity matters. Knowing you’re high in extraversion tells you something general. Knowing you’re high in enthusiasm but moderate in assertiveness tells you something much more specific about how you engage with people and situations.
The PDF versions circulating online are typically either free Big Five assessments based on the same academic model, older versions of Peterson’s materials from his university lectures, or unofficial compilations of the test questions. Some are reasonably accurate reflections of the Big Five framework. Others are simplified versions that lose the nuance Peterson’s full assessment provides. If you want the actual Understand Myself results Peterson designed, you’ll need to access it through his official platform, where it currently costs a small fee. The free PDFs are a starting point, not a substitute.
How Does the Big Five Differ From Myers-Briggs?
This is where things get genuinely interesting for anyone who has spent time with MBTI. The two frameworks are measuring related but distinct things, and understanding the difference changed how I think about both of them.
Myers-Briggs places you into one of sixteen types based on four dichotomies: Extraversion versus Introversion, Sensing versus Intuition, Thinking versus Feeling, and Judging versus Perceiving. The deeper layer of MBTI theory involves cognitive functions, the specific mental processes like Introverted Intuition or Extraverted Thinking that shape how each type perceives and processes the world. If you’ve ever wondered whether your MBTI result actually fits your experience, our guide on how cognitive functions reveal your true type is worth reading carefully before you write off your results.
The Big Five, by contrast, doesn’t assign types at all. It places you on a spectrum for each trait, acknowledging that most people fall somewhere in the middle rather than at the extremes. A 2020 study published in PubMed Central examining personality trait stability found that Big Five scores show meaningful consistency over time while also reflecting genuine change in response to life experiences, which aligns with how most of us actually experience our own personalities.
One area where the two frameworks genuinely overlap is the Extraversion dimension. Both MBTI and the Big Five measure something real about how people gain and spend energy, how much external stimulation they seek, and how they engage socially. The difference is that MBTI’s E vs I distinction treats this as a fundamental orientation that shapes your entire cognitive approach, while the Big Five treats extraversion as one of five relatively independent traits. Neither view is wrong. They’re asking slightly different questions.
What Do Your Big Five Scores Actually Mean?
Let me walk through each dimension in a way that goes beyond the textbook definition, because I’ve seen how these traits play out in real professional environments over two decades of agency work.
Openness to Experience measures intellectual curiosity, aesthetic sensitivity, and comfort with abstract ideas. High scorers tend to be imaginative, drawn to novelty, and comfortable with ambiguity. In my agency years, the highest-openness people on my teams were the ones who could sit with an undefined creative brief and generate ten genuine directions. They were also sometimes the hardest to keep focused on execution. Low scorers prefer convention and concrete thinking, which made them invaluable when a project needed disciplined delivery rather than another round of ideation.
Conscientiousness measures self-discipline, organization, and goal-directed behavior. Peterson often describes high conscientiousness as the single trait most predictive of life success across domains, and the research largely supports that claim. A landmark study published in PubMed Central found that conscientiousness predicted both job performance and longevity more reliably than most other personality variables. In my own case, my INTJ wiring gave me high conscientiousness in domains I cared about deeply, and almost none in areas I found meaningless. That selective conscientiousness caused real friction in agency environments where everything was supposed to matter equally.
Extraversion in the Big Five covers both the social engagement dimension and what Peterson calls positive emotionality, the tendency to experience enthusiasm, excitement, and reward-seeking behavior. This is where the overlap with MBTI’s introversion-extraversion becomes complex. Someone can score low on extraversion in the Big Five while still being highly curious, deeply engaged in their work, and genuinely warm with people they trust. Low extraversion doesn’t mean antisocial. It means you don’t need constant external stimulation to feel alive.
Agreeableness measures compassion and politeness, the tendency to prioritize others’ needs and maintain social harmony. High agreeableness makes someone easy to work with and genuinely empathetic, qualities that WebMD’s overview of empathic traits connects to the broader capacity for emotional attunement. Low agreeableness predicts assertiveness and competitiveness, traits that can be assets in negotiation but create friction in collaborative environments. I watched this dynamic play out in client pitches constantly. The most agreeable people on my team built the warmest client relationships. The least agreeable ones closed the most difficult deals.
Neuroticism measures emotional volatility and the tendency to experience negative emotions like anxiety, irritability, and self-doubt. Peterson is notably direct about this dimension, arguing that high neuroticism creates genuine suffering and that understanding your score is the first step toward managing it. High scorers feel things intensely and are more sensitive to threat and uncertainty. Low scorers tend toward emotional stability and resilience under pressure. Neither extreme is inherently better, but understanding where you fall helps explain a lot about how you respond to stress, criticism, and ambiguity.
Where Does Cognitive Function Theory Fit Into All This?
Peterson’s framework and MBTI cognitive functions are answering different questions, but they illuminate each other in ways that I find genuinely useful.
Take the Thinking functions as an example. Extroverted Thinking is oriented toward external systems, measurable outcomes, and logical efficiency in the world. People who lead with Te tend to score high on conscientiousness and moderate to low on agreeableness in the Big Five, because they prioritize getting things done correctly over maintaining social harmony. Introverted Thinking, by contrast, is oriented toward internal logical frameworks and precise understanding of how systems work. Ti users often score high on openness and moderate on conscientiousness, because their drive is toward understanding rather than execution.
Neither framework is complete on its own. The Big Five tells you where you fall on trait dimensions. Cognitive function theory tells you something about the specific mental processes you use to perceive and judge information. Used together, they give you a much richer picture of how you actually operate.
If you want to go deeper on the cognitive side, our cognitive functions test is a good place to start identifying your mental stack before you try to interpret your Big Five results through that lens.
Why Introverts Often Get More From Peterson’s Framework Than They Expect
There’s something about the Big Five that tends to resonate with introverts in a particular way, and I think it comes down to the absence of judgment built into the framework. MBTI can sometimes feel like it’s telling you what kind of person you are in a fixed sense. The Big Five tells you where you fall on spectrums that exist across all humans, which is a subtly different psychological experience.
Scoring low on extraversion in the Big Five doesn’t carry the same cultural weight as being labeled an introvert in a society that often treats introversion as a limitation. It simply means you require less external stimulation and social interaction to feel satisfied. That’s a description of a trait, not a verdict on your personality.
Peterson’s lectures, particularly his discussions of agreeableness and conscientiousness, also tend to validate something many introverts have felt for years without having language for it. The combination of high openness, high conscientiousness in selective domains, and low extraversion describes a person who does their best thinking alone, produces exceptional work when genuinely engaged, and finds most small talk genuinely draining rather than just mildly inconvenient. That’s not a flaw. That’s a profile.
A 2024 analysis from 16Personalities’ global data found that introverted personality types are distributed fairly evenly across the global population, which undercuts the idea that introversion is somehow a minority condition requiring accommodation. It’s simply one end of a normal distribution.
What I’ve noticed in my own experience is that introverts often score higher on the depth-of-processing side of openness and lower on the novelty-seeking side. We’re drawn to complexity and meaning rather than stimulation for its own sake. Truity’s research on deep thinking tendencies connects this pattern to the kind of reflective, analytical processing that many introverts recognize in themselves immediately.
How Peterson’s Framework Applies to Sensing and Perceiving
One dimension of personality that the Big Five handles differently than MBTI is the sensing versus intuition axis. MBTI treats this as a fundamental cognitive orientation, the difference between attending to concrete present-moment reality versus abstract patterns and possibilities. Peterson’s framework doesn’t have a direct equivalent, but the openness dimension captures some of this territory.
High openness correlates with the kind of pattern recognition and abstract thinking associated with MBTI’s Intuition preference. Low openness correlates with the concrete, practical, present-focused orientation associated with Sensing. But they’re not the same thing. A person can score low on openness and still have a rich inner world. A person can score high on openness and still be deeply grounded in practical reality.
This is where Extraverted Sensing becomes an interesting lens. Se is the cognitive function associated with immediate sensory engagement, physical presence, and real-time responsiveness to the environment. High Se users are often highly present, action-oriented, and energized by direct experience. In Big Five terms, they might score moderately on openness but high on extraversion and low on neuroticism, a profile that looks very different from the high-openness, low-extraversion pattern common in intuitive introverts.
Neither profile is superior. They’re different ways of being oriented toward the world, and understanding which pattern fits you helps explain a lot about what kinds of work, environments, and relationships feel natural versus draining.
What the Research Says About Big Five Validity
One reason Peterson advocates so strongly for the Big Five over other personality frameworks is its empirical foundation. The OCEAN model has been tested across cultures, languages, age groups, and methodologies in ways that most personality assessments haven’t been. Its dimensions consistently emerge from factor analyses of personality data, which means they reflect genuine patterns in human behavior rather than theoretical constructs imposed on the data.
The APA’s own coverage of personality research, including work on self-perception and personality reflection, highlights how people’s understanding of their own traits often diverges from how others perceive them, which is one reason structured assessments can be more revealing than simple self-reflection. We have blind spots about ourselves. A well-designed assessment can surface patterns we’ve been living inside without fully seeing.
That said, no personality assessment is a perfect measurement tool. The Big Five has limitations. Self-report assessments are subject to social desirability bias, meaning people sometimes answer questions in ways that reflect who they want to be rather than who they actually are. Results can shift depending on your mood, your current life circumstances, and how you interpret ambiguous questions. Peterson’s own materials acknowledge this, which is part of why his platform provides detailed explanations of each dimension rather than just a score.
The practical implication is that your Big Five results are most useful when you approach them as a starting point for reflection rather than a definitive verdict. Take the results seriously. Sit with the dimensions that surprise you. Notice where the description fits your actual behavior in specific situations, not just your idealized self-image.
Using Peterson’s Framework Alongside MBTI for Deeper Self-Knowledge
My honest recommendation, after years of working with both frameworks personally and watching them play out across dozens of team dynamics, is to use them together rather than treating them as competing systems.
Start with your Big Five scores to get a clear picture of where you fall on the five trait dimensions. Pay particular attention to your neuroticism score, because it has the most direct bearing on your day-to-day emotional experience, and to your conscientiousness score, because it explains a lot about how you approach commitments and follow-through. Then layer in MBTI to understand the specific cognitive processes you use most naturally.
If you haven’t established your MBTI type yet, our free MBTI personality test is a good place to start before you try to interpret the two frameworks in relation to each other. Having both sets of results gives you a much richer vocabulary for understanding your own patterns.
One thing I’ve found particularly useful is looking at where the two frameworks seem to tell slightly different stories. If your Big Five scores suggest high agreeableness but your MBTI cognitive functions suggest strong Te or Ti, that tension is worth exploring. It might mean you’ve developed agreeableness as an adaptive behavior in professional contexts while your natural cognitive orientation is more analytical and less socially accommodating. That kind of nuance is invisible when you’re only looking at one framework.
The 16Personalities research on team collaboration makes a related point: personality frameworks are most useful when they help people understand and articulate their differences rather than when they’re used to categorize or limit anyone. That’s true whether you’re using Big Five, MBTI, or any other system.
A Note on Finding and Using the PDF Version
If you’re searching for the Jordan Peterson personality test as a PDF specifically, consider this you’re likely to find and what each version is worth.
Free Big Five PDF assessments based on the IPIP (International Personality Item Pool) are academically grounded and freely available. They use the same theoretical model as Peterson’s Understand Myself assessment and will give you reasonably accurate scores on the five main dimensions. What they won’t give you is the sub-trait breakdown or the detailed interpretive materials Peterson’s platform provides.
Unofficial PDFs claiming to be Peterson’s test are typically either the IPIP assessment repackaged or simplified versions that lack the psychometric rigor of the original. They’re not useless, but treat them as an introduction rather than a definitive assessment.
Peterson’s actual Understand Myself platform is the most complete version of his work, and the interpretive reports it generates are genuinely detailed. The cost is modest, and if you’re serious about using the framework for real self-understanding, it’s worth paying for the full version rather than relying on a PDF approximation.
Whatever version you use, the value comes from what you do with the results. Reading your scores once and moving on gives you almost nothing. Sitting with the descriptions, testing them against your actual behavior in specific situations, and discussing them with people who know you well, that’s where the framework earns its place in your self-understanding toolkit.
What I Wish I’d Known Earlier About Personality Frameworks
There’s a version of me from my mid-thirties, running a mid-sized advertising agency and completely baffled by my own leadership style, who would have found Peterson’s framework enormously clarifying. Not because it would have told me anything I couldn’t have figured out eventually, but because it would have given me a precise vocabulary for things I was experiencing without language for.
My neuroticism scores have always been moderate to high. I feel criticism intensely, I replay difficult conversations, and I experience anxiety about outcomes that most of my colleagues seemed to shrug off. For years I interpreted that as a weakness, something to suppress or manage away. Peterson’s framework helped me see it differently. High neuroticism often correlates with high conscientiousness and high openness, which means the same sensitivity that makes you anxious also makes you careful, thorough, and genuinely attuned to complexity. That’s not a bug. That’s a trade-off.
My extraversion scores are low, which surprised exactly no one who has worked with me. What was more illuminating was understanding that my low extraversion combined with high openness creates a specific profile: someone who is energized by ideas and depth rather than social stimulation, who needs significant alone time to process and create, and who finds large group dynamics genuinely taxing rather than just mildly inconvenient. Once I stopped trying to perform a version of extraversion that didn’t fit my wiring, my leadership actually improved. I stopped draining my energy on social performance and started investing it in the analytical and creative work I do best.
That shift didn’t happen because of a personality test. It happened because I finally took the test results seriously instead of filing them away as interesting but not actionable. Personality frameworks only matter if you actually use them.

Frequently Asked Questions
Is the Jordan Peterson personality test the same as the Big Five?
Peterson’s Understand Myself assessment is built on the Big Five framework, also called the OCEAN model, which measures Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. His version adds granularity by measuring two sub-traits within each dimension, giving you ten scores instead of five. Free PDF versions circulating online are typically standard Big Five assessments based on the same academic model, but they lack the sub-trait breakdown and detailed interpretive materials Peterson’s platform provides.
How does the Jordan Peterson personality test differ from Myers-Briggs?
The Big Five places you on continuous spectrums for five traits without assigning a fixed type. Myers-Briggs assigns you to one of sixteen types based on four dichotomies and is grounded in cognitive function theory. The two frameworks overlap most on the extraversion dimension but are measuring related rather than identical things. Many people find it useful to take both assessments and compare results, since they illuminate different aspects of personality.
Where can I find the Jordan Peterson personality test PDF for free?
Free Big Five assessments based on the IPIP (International Personality Item Pool) are academically grounded and freely available online, including as downloadable PDFs. These use the same theoretical model as Peterson’s assessment. For Peterson’s specific version with sub-trait scores and detailed interpretive reports, you’ll need to access his Understand Myself platform directly, which charges a modest fee. Free PDFs are a reasonable introduction but shouldn’t be treated as equivalent to the full assessment.
What does a low extraversion score mean on Peterson’s test?
A low extraversion score in the Big Five indicates that you require less external stimulation and social interaction to feel satisfied, that you tend to find large group environments draining rather than energizing, and that you likely do your best thinking in quieter, more solitary conditions. Peterson’s framework breaks extraversion into two sub-traits: enthusiasm (positive emotionality and social warmth) and assertiveness (dominance and drive). You can score low on one while scoring moderately on the other, which gives a more nuanced picture than a single extraversion score provides.
Is the Big Five more accurate than MBTI for understanding personality?
The Big Five has stronger empirical support from academic personality research and is generally considered more scientifically validated than MBTI. Its dimensions emerge consistently from factor analyses of personality data across cultures and methodologies. That said, MBTI’s cognitive function framework offers a different kind of insight, particularly around how people process information and make decisions. Both frameworks have genuine value. The most useful approach is to use them together rather than treating them as competing systems, since they answer different questions about how you operate.
