Which Personality Traits Predict Career Success? 5 Key Findings

Your personality traits career success story begins long before your first promotion. Research suggests that the Big Five personality dimensions — conscientiousness, neuroticism, extraversion, agreeableness, and openness — can shape not only how much you earn, but also how satisfied you feel in your work over the long term. Understanding this connection gives you a powerful head start in making smart, self-aware career decisions.

A research team in the United States tracked 731 participants over a 10-year period, collecting data on their personality profiles and key career outcomes. The findings, published in the paper Personality and Career Success: Concurrent and Longitudinal Relations, revealed striking links between specific personality characteristics and outcomes such as annual income, job satisfaction, and occupational prestige. In this article, we break down exactly what was found — and what it means for your own career path.

Once again, personality researcher and author of Villain Encyclopedia, Tokiwa (@etokiwa999), will provide the explanation.

What Does “Career Success” Actually Mean? Objective vs. Subjective Measures

Career success is not a single, one-dimensional concept — it has both objective and subjective sides, and both matter equally. Understanding this distinction is essential before exploring how personality traits career success research is measured and interpreted.

Objective career success refers to externally visible, measurable outcomes that others can observe and verify. Subjective career success, on the other hand, reflects how a person feels about their own work life — their inner sense of fulfillment and meaning. The landmark 10-year study used 3 primary indicators to capture this multidimensional picture:

• Occupational prestige — the social status and respect associated with a person’s profession (e.g., doctors, lawyers, and senior managers tend to rank high)
• Income level — annual earnings, which represent a classic, quantifiable marker of professional achievement
• Job satisfaction — a person’s subjective assessment of how meaningful, rewarding, and enjoyable their work feels on a day-to-day basis

By examining all 3 dimensions together, researchers were able to draw a far richer and more accurate portrait of career outcomes than income alone could provide. This framework is especially useful when thinking about a career change personality test or any self-assessment tool — because “success” must be defined on your own terms before it can be pursued effectively.

Objective Career Success: Occupational Prestige and Income

Occupational prestige and income are the 2 most commonly used objective indicators of career success. Occupational prestige is defined as the level of social recognition and status that society assigns to a given profession. Income, more straightforwardly, reflects how much a person earns in a given year.

• Professions requiring high levels of expertise — such as medicine, law, or engineering — typically carry high prestige scores
• Managerial and executive roles within organizations are also regarded as high-prestige positions
• Generally speaking, higher annual income correlates with higher perceived objective success in most professional contexts

It is worth noting that prestige and income, while often correlated, do not always move in the same direction. A nurse, for example, may earn a modest salary yet hold significant social respect. The research examined both indicators separately in order to detect these nuances in how occupational success traits actually play out across different personality profiles.

Subjective Career Success: Why Job Satisfaction Is Just as Important

Job satisfaction is the defining measure of subjective career success, and research consistently shows it has profound effects on long-term well-being and performance. It captures how engaged, fulfilled, and motivated a person feels in their daily work — something that cannot be read from a pay stub or a job title alone.

Studies indicate that high job satisfaction tends to produce several meaningful benefits:

• Lower stress levels — people who find their work meaningful tend to experience less chronic stress and maintain better mental health overall
• Higher performance — intrinsic motivation, fueled by satisfaction, tends to drive stronger output and creativity than external rewards alone
• Greater organizational loyalty — satisfied employees are less likely to leave, which benefits both the individual (career continuity) and the organization (reduced turnover)

Conversely, persistently low job satisfaction is associated with a significantly elevated risk of burnout — a state of emotional exhaustion that can derail even the most externally “successful” career. This is precisely why personality and job satisfaction research is such a crucial area of study. A high salary without satisfaction, as the data suggest, may not represent genuine career success at all.

The Big Five Personality Traits and Career Outcomes: What the 10-Year Study Found

The 10-year longitudinal study of 731 participants produced some of the clearest evidence yet linking Big Five career outcomes to specific personality dimensions. The Big Five model — also known as the OCEAN model — describes personality across 5 broad traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Each was assessed at the start of the study, and career outcomes were tracked over the following decade.

The study’s design gave it several important strengths that make its findings particularly credible:

• Large sample size — 731 participants provides enough statistical power to identify genuine trends rather than coincidental patterns
• Long follow-up period — 10 years is long enough to observe real career development, including promotions, job changes, and income growth
• Multiple success measures — using 3 distinct career outcome variables (prestige, income, satisfaction) allowed for a nuanced, multi-angle analysis

The results confirmed that personality does matter — but that different traits influence different aspects of career success in different ways, and at different stages of a career. Below, we explore the most significant findings in detail.

What is Big Five Personality Test? Overview, Genetics & MBTI

Neuroticism and Job Performance: How Emotional Stability Shapes Your Career

Low neuroticism — that is, high emotional stability — is one of the strongest personality predictors of both higher income and greater job satisfaction identified in the study. This connection between neuroticism and job performance has been observed across multiple research contexts, making it one of the most robust findings in occupational psychology.

Neuroticism is defined as a tendency to experience negative emotions such as anxiety, worry, sadness, and irritability more frequently and more intensely than average. People high in neuroticism tend to be more easily destabilized by stress, interpersonal conflict, or uncertainty. In contrast, people low in neuroticism maintain their composure more readily and recover from setbacks faster.

The longitudinal data showed that individuals with lower neuroticism scores tended to display the following career characteristics:

• Higher average annual income — emotionally stable individuals are more likely to take on demanding, high-responsibility roles that command premium compensation
• Higher job satisfaction scores — they are better able to focus on the rewarding aspects of work rather than fixating on frustrations or fears
• Lower rates of depressive symptoms — which in turn supports sustained engagement and productivity over the long term

From a practical standpoint, the mechanism behind this finding seems logical. High-neuroticism individuals may struggle to negotiate salaries assertively, may avoid taking on visible stretch assignments due to fear of failure, or may experience frequent stress-induced performance dips. Over a decade, these small disadvantages compound into meaningful gaps in income and satisfaction. Research suggests that even moderate improvements in emotional regulation can help counteract some of these effects.

The 3 Neuroticism Facets Most Linked to Income: Anxiety, Depression, and Vulnerability

Within the broader neuroticism dimension, 3 specific facets showed the clearest negative correlation with annual earnings: anxiety, depression, and vulnerability to stress.

These 3 characteristics can be understood as follows. Anxiety refers to a chronic tendency to worry about future outcomes and perceive threats where others see manageable challenges. Depression, in this personality context, means a habitual low mood and reduced capacity to experience positive emotions. Vulnerability describes how quickly a person’s coping resources become depleted under pressure — essentially, how easily they “break” when circumstances become difficult.

• Resilience — people low on all 3 facets tend to bounce back quickly from professional setbacks, maintaining forward momentum in their careers
• Emotional steadiness — they are less likely to make impulsive decisions driven by anxiety or dejection, leading to more consistent professional judgment
• Effective stress management — lower vulnerability means they can sustain high performance even in demanding or high-pressure roles

Individuals who score high on these 3 sub-traits are not doomed to lower earnings — but the research does suggest they may benefit especially from developing deliberate stress-management practices, such as mindfulness, regular exercise, or structured problem-solving routines, to reduce the career impact of these tendencies.

Conscientiousness and Career: The Single Most Consistent Predictor of Long-Term Success

Of all the Big Five traits, conscientiousness and career success show the most consistent positive relationship across virtually every measure studied — including income, job satisfaction, and occupational achievement. This finding aligns with a large body of prior research making conscientiousness arguably the most career-relevant personality trait in the entire Big Five framework.

Conscientiousness is defined as the tendency to be organized, disciplined, reliable, and goal-directed. People high in conscientiousness approach tasks with care and thoroughness; they follow through on commitments, plan ahead, and maintain high personal standards. In everyday terms, they are the people who meet deadlines, keep their workspace tidy, and stay focused on long-term objectives even when short-term temptations arise.

The 10-year study found that highly conscientious individuals tended to show the following profile:

• Above-average annual income — consistent effort and reliability lead to stronger performance evaluations and faster advancement
• Higher job satisfaction — the sense of accomplishment from completing tasks thoroughly produces genuine fulfillment
• Stronger achievement motivation — they set ambitious but realistic goals and pursue them persistently
• Greater self-discipline — they are less likely to procrastinate or abandon projects under difficulty

Importantly, conscientiousness appears to benefit careers at virtually every stage — not just at the beginning. This is a key difference from extraversion (discussed below), whose career benefits tend to be more concentrated in the early years. Whether you are a recent graduate or a mid-career professional, investing in the habits associated with high conscientiousness — planning, organization, follow-through — is likely to pay dividends across the entire arc of your career. People considering a career change personality test would do well to pay close attention to their conscientiousness scores as a reliable signal of future performance potential.

Extraversion, Assertiveness, and Income Growth: A Stage-Specific Advantage

Extraversion tends to be most beneficial for income growth during the early stages of a career, with its influence appearing to diminish as careers mature. This stage-specific pattern is one of the more nuanced findings from the study, and it carries important practical implications for how people of different personality types should approach career development at different life stages.

Extraversion is defined as a personality orientation toward the external world — characterized by sociability, talkativeness, assertiveness, and a tendency to seek out stimulation and connection with others. Extraverts tend to feel energized by social interaction and are generally comfortable in the spotlight.

The study found the following pattern regarding extraversion and income:

• High early-career extraversion predicted higher income 10 years later — suggesting that the networking and self-promotion advantages of extraversion yield durable financial returns
• This effect was not observed in mid-to-late career phases — indicating that other traits, particularly conscientiousness, become more dominant success drivers over time

The underlying logic here is fairly intuitive. In the early career phase, much of what determines income is visibility — getting noticed by the right people, building a professional network, advocating for oneself in salary negotiations, and being willing to speak up in meetings. Extraverts naturally tend to excel in all of these areas. However, as careers advance, technical expertise, reliability, and the ability to lead sustained projects often matter more than social energy — which is where conscientious, emotionally stable individuals can catch up and even overtake their more extraverted peers.

Within the extraversion dimension, 2 specific facets — assertiveness (the tendency to take charge and express opinions confidently) and activity level (drive and enthusiasm for pursuing goals) — showed particularly strong links to income growth. People who combine these qualities with high conscientiousness appear especially well-positioned for long-term earning potential.

Personality Traits and Occupational Prestige: The Role of Confidence and Trust

Achieving high occupational prestige tends to require a different personality profile than maximizing income — with low depressive tendency, high interpersonal trust, and strong self-efficacy emerging as the 3 key characteristics linked to prestigious careers.

It is worth noting that the research found occupational prestige to be somewhat less strongly correlated with personality than income was. Nevertheless, 3 clear personality signals emerged from the data that distinguished those who reached high-prestige positions from those who did not.

Low Depressive Tendency: Staying Positive Enough to Aim High

People with lower levels of depressive tendency were significantly more likely to hold high-prestige occupations, such as physician, attorney, or senior executive roles. Depressive tendency, in this context, refers to a stable personality disposition toward low mood and reduced experience of positive emotions — not clinical depression, but a chronic mildly pessimistic baseline.

• People with low depressive tendency tend to maintain an optimistic outlook that sustains long-term effort toward demanding goals
• They are less likely to give up when the path to a prestigious career involves years of education, training, or competitive gatekeeping
• Their resilience in the face of setbacks helps them persist through the kind of extended challenge that high-prestige careers typically require

In contrast, individuals with a higher depressive baseline may find their ambitions consistently undermined by self-doubt and a tendency to see obstacles as insurmountable. This can result in settling for less challenging roles even when the underlying ability is present.

High Interpersonal Trust: The Foundation of Professional Relationships

People who tend to trust others more readily are more likely to attain high-prestige positions, research indicates — likely because interpersonal trust enables the kind of collaborative relationships that are essential in expert and leadership roles.

• Stronger relationships with colleagues and supervisors — trusting others creates conditions where genuine collaboration and mentorship can flourish
• Better client and stakeholder relationships — high-trust individuals tend to inspire confidence in others, which is particularly valuable in client-facing, advisory, or leadership roles
• More effective teamwork — teams perform better when members extend good faith to one another, and high-trust individuals often catalyze this dynamic

High interpersonal trust is a facet of the broader agreeableness dimension. Interestingly, while overall agreeableness does not always predict higher income (and can sometimes be associated with lower earnings, as highly agreeable people may negotiate less assertively), the specific trust facet appears to support prestige attainment by enabling the kind of deep professional relationships that lead to mentorship, sponsorship, and recognition.

High Self-Efficacy: Believing You Can Reach the Top

Self-efficacy — the belief in one’s own ability to achieve goals and handle challenges — was strongly associated with attaining high-prestige careers. People with high self-efficacy are more willing to pursue demanding roles and persist through the prolonged investment that prestigious professions typically require.

• Willingness to pursue high-skill roles — they do not self-select out of demanding opportunities before even trying
• Stronger leadership presence — confidence in one’s own judgment helps others feel led, which is critical for managerial and expert roles

In contrast, individuals with low self-efficacy may possess strong technical skills yet consistently undersell themselves, avoid stretch roles, or accept limited career trajectories out of unfounded self-doubt. Developing a more accurate and confident self-appraisal — often through accumulated small wins and deliberate skill-building — can meaningfully improve occupational success traits over time.

5 Big Five Traits That Predict Higher Income

Actionable Advice: How to Leverage Your Personality Traits for Career Growth

Understanding the link between personality and career outcomes is only valuable if it translates into practical action. Here is a framework for turning these research findings into concrete career strategies — whether you are just starting out or considering a major career change.

If You Score High in Neuroticism: Build Stress-Management as a Career Skill

High neuroticism is not a fixed sentence. Research on neuroplasticity and behavioral change suggests that emotional regulation is a learnable skill. Why it works: Reducing the frequency and intensity of anxious or depressive responses frees up cognitive resources for higher-level professional tasks. How to practice it: Consider structured approaches such as cognitive behavioral techniques, mindfulness-based stress reduction, regular aerobic exercise (which has strong evidence for mood stabilization), and deliberately choosing roles where workload and expectations are realistic rather than chronically overwhelming. Even a modest reduction in baseline anxiety can compound into significantly better career outcomes over a decade.

If You Score High in Conscientiousness: Lean Into Long-Term Roles and Leadership

High conscientiousness is one of the most durable advantages a professional can have. Why it works: Organizations consistently reward reliability, follow-through, and disciplined goal pursuit — all core expressions of high conscientiousness. How to practice it: Actively seek roles with clear deliverables, long-term project responsibility, and visible performance metrics. Volunteer for leadership positions where your organizational strengths will be on display. Be mindful, however, of a common pitfall for highly conscientious people — perfectionism — which can slow output and create unnecessary stress. Learning to calibrate “good enough” versus “perfect” is an important counterbalance.

If You Score High in Extraversion: Front-Load Your Career Networking Investment

The research suggests extraversion’s income advantage is most pronounced in the early career phase. Why it works: The professional networks built in the first 5 to 10 years of a career tend to generate referrals, opportunities, and sponsors that pay off for decades. How to practice it: Invest heavily in networking events, professional associations, and mentorship relationships early on. Use your natural assertiveness to negotiate starting salaries and early promotions — these set the baseline from which all future raises are calculated. As your career matures, consciously shift focus toward deepening expertise and reliability to sustain momentum beyond the early-career extraversion premium.

If You Score Low in Extraversion: Invest in Visibility Through Output Quality

Introverts can absolutely achieve strong career outcomes — the data clearly supports this. Why it works: The early-career extraversion advantage largely disappears by mid-career, where conscientiousness and emotional stability dominate. How to practice it: Focus on producing exceptionally high-quality work that speaks for itself. Build deep expertise in a valued domain. Practice assertive communication in lower-stakes settings (such as written channels) before extending it to high-visibility scenarios. Consider roles in fields where depth of knowledge and reliability are more valued than constant social interaction — many high-prestige, high-income professions fit this description.

For Everyone: Use Personality Awareness to Make Better Job Fit Decisions

Perhaps the most powerful application of this research is in evaluating job fit — how well a particular role, organization, or industry aligns with your natural personality tendencies. Why it works: Research consistently shows that person-environment fit predicts both performance and satisfaction better than either factor alone. How to practice it: Before accepting a role or making a career change, honestly assess whether the daily demands of that job play to your personality strengths. A high-neuroticism individual may thrive in a structured, predictable environment but struggle in a chaotic, high-uncertainty one. A highly conscientious person may feel deeply frustrated in an organization that rewards improvisation over planning. Using a career change personality test as a structured reflection tool — not a definitive verdict — can help surface these fit considerations before they become costly mistakes.

Frequently Asked Questions

Can changing your personality traits improve your career success?

Personality traits tend to be relatively stable, but they are not completely fixed. Research suggests that behavioral patterns associated with traits like conscientiousness and emotional stability can be strengthened through deliberate practice. For example, developing consistent routines, practicing stress management, and building self-regulation habits may produce meaningful improvements in career-relevant traits over time — even if your core temperament remains largely the same.

Which personality trait has the biggest overall impact on career success?

Based on the available research, conscientiousness tends to show the most consistent positive relationship with career outcomes across the full career lifespan. It predicts both higher income and higher job satisfaction, and its advantages appear to strengthen — rather than diminish — as a career matures. Low neuroticism (high emotional stability) is a close second, particularly for income and well-being outcomes.

Is taking a personality test before a career change actually useful?

A career change personality test can be a genuinely valuable reflection tool when used appropriately. It helps identify your natural strengths and potential blind spots, and prompts thinking about which work environments and role types are likely to suit you well. However, personality assessments should be treated as one input among many — not as a definitive career prescription. Individual motivation, acquired skills, and environmental factors also play major roles in determining career outcomes.

Does high extraversion guarantee a higher income?

Not necessarily. Research suggests that extraversion’s income advantage is most pronounced in the early stages of a career, where networking and self-promotion are particularly impactful. By mid-career, the income gap between high and low extraverts tends to narrow significantly. Conscientious, emotionally stable introverts often match or surpass their extraverted peers in income over a full career arc — particularly in fields that reward deep expertise and reliability.

How does neuroticism affect job satisfaction specifically?

People high in neuroticism tend to experience lower job satisfaction because they are more sensitive to workplace stressors, interpersonal friction, and perceived setbacks. Their negativity bias leads them to weight frustrations more heavily than rewards, which erodes satisfaction even in objectively good jobs. Research consistently shows that emotional stability — the opposite of neuroticism — is one of the strongest personality predictors of sustained job satisfaction across different occupations and industries.

Can introverts reach high-prestige careers?

Absolutely. The research on occupational prestige found that the key differentiating traits were low depressive tendency, high interpersonal trust, and strong self-efficacy — none of which are exclusively extraverted qualities. Many of the world’s highest-prestige professions, including medicine, law, academia, and engineering, reward depth of expertise, analytical rigor, and reliability — characteristics that introverts frequently excel at. Career success is highly achievable across the full introvert-extravert spectrum.

Should I prioritize income or job satisfaction in my career planning?

Research suggests that both matter for genuine career well-being, and that treating them as opposites is often a false choice. The personality profile most associated with high income — low neuroticism and high conscientiousness — is also the profile most associated with high job satisfaction. This suggests that investing in emotional stability and disciplined work habits tends to improve both dimensions simultaneously, making it possible to pursue a career that is rewarding in every sense of the word.

Summary: What Your Personality Tells You About Your Career Path

The evidence is clear: personality traits career success connections are real, measurable, and durable across time. The 10-year longitudinal study of 731 participants demonstrated that low neuroticism and high conscientiousness are the 2 most broadly influential personality dimensions for career outcomes — consistently predicting both higher income and greater job satisfaction. Extraversion provides a meaningful early-career income boost, particularly through its assertiveness and activity facets, though its edge fades by mid-career. For occupational prestige, emotional positivity, trust in others, and self-belief appear to be the most critical differentiating traits.

Crucially, none of these findings are deterministic. Personality shapes tendencies — it does not fix outcomes. Understanding your own personality profile empowers you to make smarter decisions: choosing environments where your natural strengths are amplified, proactively building skills to compensate for challenging tendencies, and setting career goals that align with who you genuinely are. If this article has prompted you to think about your own traits more carefully, a good next step is to explore your Big Five profile in detail — and discover which career environments are most likely to bring out your best.
