Big Five Aspects Scale Explained: Jordan Peterson's Personality Test

Origins and Scientific Foundations of the Big Five Aspects Scale

The Big Five Aspects Scale, often abbreviated as BFAS, represents a refined evolution in personality psychology, offering a nuanced view beyond the broad Big Five traits. Developed through rigorous factor analysis, it dissects each of the five primary personality domains into two distinct aspects, providing 10 sub-traits in total. This intermediate level of granularity bridges the gap between overly broad domains and highly specific facets, enabling more precise self-understanding and prediction of behavior.

The scale emerged from a landmark 2007 study conducted by researchers Colin G. DeYoung from Yale University, Lena C. Quilty from the Centre for Addiction and Mental Health, and Jordan B. Peterson from the University of Toronto. Published in the Journal of Personality and Social Psychology, their work analyzed data from 481 community adults using established inventories like the NEO-PI-R and AB5C-IPIP. They identified consistent patterns where two correlated aspects emerged within each Big Five domain. To operationalize this, they created the 100-item BFAS questionnaire, validated in a separate university sample of 480 students, demonstrating high reliability (Cronbach's alpha 0.81-0.89) and validity against other measures.Read the original research paper here.

This foundation has stood the test of time, with thousands of citations and ongoing validations worldwide, including recent short-form adaptations like the BFAS-40 for efficient use in academic and clinical settings.

Jordan Peterson's Role in Bringing BFAS to a Wider Audience

Jordan B. Peterson, a clinical psychologist and former professor at the University of Toronto, played a pivotal role in popularizing the BFAS. Leveraging his academic expertise and public platform, he co-authored the foundational paper and launched Understand Myself, an online platform delivering personalized BFAS reports. Users complete 100 self-rating items on a 5-point Likert scale, with results benchmarked against a diverse sample of over 10,000 individuals varying in age, gender, and background.

The platform's reports provide percentile rankings and vivid descriptions tailored to score ranges, explaining how traits manifest in daily life, relationships, and work. For a modest fee, users gain insights into why they act as they do—whether it's a high score in Assertiveness driving leadership or low Orderliness leading to creative chaos. Peterson's integration of philosophical and practical advice in interpretations resonates particularly with students and academics navigating complex career paths in higher education.

Unpacking the Five Domains and Their Ten Aspects

At its core, the BFAS measures five overarching domains—Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism—each split into two aspects. This structure reveals subtleties; for instance, high Extraversion might stem from bubbly Enthusiasm or commanding Assertiveness.

Openness to Experience: Encompasses aesthetic sensitivity and intellectual curiosity. Openness reflects appreciation for art, imagination, and novelty, while Intellect involves quickness with ideas, abstract thinking, and problem-solving. High scorers often pursue creative fields like literature or fine arts in university.

Conscientiousness: Linked to goal pursuit and self-control. Industriousness is about diligence and persistence in tasks, ideal for research-heavy academic roles. Orderliness favors structure, planning, and rule-following, suiting administrative positions in colleges.

Extraversion: Tied to positive emotions and social energy. Enthusiasm brings warmth and gregariousness, great for teaching. Assertiveness involves dominance and leadership, key for deans or department heads.

Agreeableness: Centers on interpersonal harmony. Compassion drives empathy and emotional attunement, vital in counseling services. Politeness emphasizes respect for norms and deference, fostering collaborative campus environments.

Neuroticism: Associated with negative emotions. Withdrawal manifests as anxiety and avoidance under stress. Volatility involves irritability and emotional swings, which can challenge but also fuel passionate advocacy in academia.

These aspects correlate moderately within domains (e.g., Volatility-Withdrawal r=0.71) but show unique cross-domain links, like Intellect with Assertiveness, forming clusters predictive of success in intellectual pursuits.

How the Jordan Peterson Personality Test Works in Practice

Taking the test is straightforward: Respond to statements like 'I get angry easily' or 'I like to solve complex problems' based on typical behavior. Scores are percentiles relative to the normed sample, with detailed narratives. For example, someone at the 85th percentile in Industriousness learns they outperform 85% of people in sustained effort, correlating with higher GPAs and tenure-track persistence.

• Select phrases that best match your agreement/disagreement.
• Complete in 15-20 minutes without overthinking.
• Receive instant report with graphs, descriptions, and interpersonal implications.
• Avoid retakes post-report to maintain validity.

In higher education, advisors use such tools to match students' profiles to majors—high Intellect to STEM, high Compassion to social work programs.

BFAS Applications in University Student Success and Performance

Research consistently links BFAS traits to academic outcomes. A 2025 Frontiers in Psychology study found Conscientiousness, particularly Industriousness, strongly predicts GPA across global universities, explaining up to 15% variance in performance. High Openness/Intellect aids in innovative research, while low Neuroticism (stability) buffers against dropout.

At institutions like the University of Oregon's Personality and Social Dynamics Lab, BFAS refines Big Five measures for studying student engagement. Meta-analyses of 84 studies confirm Extraversion boosts group project success, Agreeableness enhances peer learning, but high Volatility hinders exam focus.

Case in point: A University of Central Florida thesis used BFAS on 443 undergraduates, revealing low Politeness correlated with social anxiety, impacting seminar participation. Interventions targeting aspects—like mindfulness for Withdrawal—improve retention rates by 10-20%.

Career Counseling and Major Selection in Higher Education

Universities increasingly integrate BFAS-like tools into career centers. High Industriousness suits rigorous PhD programs, while Assertiveness fits competitive faculty roles. A study on B-school students in India validated BFAS for predicting management career fit, with Intellect driving analytical paths.

For example, at Syracuse University, personality assessments guide undecided freshmen: Low Orderliness? Avoid accounting; high Enthusiasm? Consider education. Emotional stability (low Neuroticism) proves crucial for high-stakes fields like medicine, reducing burnout by 25% per longitudinal data.

• Match Conscientiousness to workload-heavy majors like engineering.
• Use Openness for interdisciplinary studies.
• Balance Extraversion for teaching vs. research tracks.

Research and Validation in Academic Environments

BFAS's academic pedigree shines in university labs. Recent 2025 validations in German, French, Italian, and Libyan samples confirm cross-cultural reliability, with short forms like BFAS-S for large-scale student surveys. A Taylor & Francis study introduced BFAS-40, retaining 90% variance with half the items—perfect for busy college research.

Genetic underpinnings, noted in the original paper (correlations up to 0.93 with heritability factors), intrigue psych genomics departments. Ongoing work at Yale and Toronto explores BFAS in predicting postdoc success and faculty collaboration.

Limitations, Criticisms, and Complementary Tools

While robust, BFAS relies on self-reports, potentially biased by social desirability. Cultural nuances affect interpretations—Western norms favor high Industriousness. Critics note it overlooks situational influences, but hybrids with situational judgment tests address this.

Alternatives like NEO-PI-R offer more facets; free IPIP versions approximate BFAS. In higher ed, combining with GPA and interviews yields holistic profiles.

Real-World Case Studies from College Campuses

At Florida State University, BFAS-informed advising reduced major changes by 18%. A Libyan university adapted BFAS-S for Arab students, linking high Compassion to counseling careers. Peterson's own Toronto lab used it to mentor grad students, with high Assertiveness correlating to publication rates.

Future Outlook: BFAS in Evolving Higher Education

As AI analyzes personalities, BFAS could personalize curricula—low Orderliness students get flexible syllabi. Post-2026 studies forecast VR adaptations for immersive trait exploration. For academics, it promises better team-building, reducing departmental conflicts by 15% via aspect-matching hires.

Stakeholders from students to administrators gain actionable insights: Define goals around strengths, mitigate weaknesses through training. This tool empowers proactive career navigation in competitive academia.
