There are close to eight billion people in the world today, but psychologists believe they can be largely categorised into five groups.
The Big Five Personality Traits is a model that’s widely recognised and scientifically validated way to measure and understand human personalities.
As unique as we may all think we are, the Big Five Personality Traits put forth a theory that all that we are, despite our quirks and habits, can be grouped neatly into just five categories.
What are the Big Five Personality Traits?
They can be abbreviated into OCEAN.
- Openness to experience: How we explore, seek, and attend to stimulation, within and beyond us
- Conscientiousness: How well and thoroughly we perform our duties
- Extraversion: How social we are
- Agreeableness: How we put the needs of others before our own)
- Neuroticism: How stable we are when confronted with negative emotions like anger and anxiety)
For each of the categories, imagine a spectrum of two extremes. For example, very agreeable versus not agreeable at all. Then, picture where you would fall on this scale.
You can try the test for yourself here.
What is the benefit of understanding the Big Five Personality Traits in today’s world?
Personality tests may seem a little cringe at first, but they help us know ourselves better — and in turn, helps us make better decisions in life.
Knowing your personality can help you determine:
- What to study in college
- What career to choose
- How well we want to do in our jobs
How you answer these questions can have a big impact on your life. This study between lifelong singles and those in relationships describes how those who score high in extraversion and openness are more likely to get out, meet people, and potentially find themselves in a relationship that will force them to try out new things.
On the other hand, those who were lifelong singles reported lower levels of extraversion, openness, and conscientiousness.
Another example can be linked to gender. This study between 410 physical education students in China showcased how neuroticism correlated with higher aggression, agreeableness was linked to lower physical aggression, and conscientiousness was associated with reduced verbal aggression. From the results, male students exhibited higher physical aggression, while female students showed more anger.
All this to say: Our personalities are consistent in driving our behaviour. Who we are ultimately influences how we react or respond to people and situations at work.
The Big Five Personality Traits and the best jobs for each
1. Extraversion
Extraversion is one of the Big Five Personality Traits, and it describes how outgoing and social you are. If you score high on extraversion, you tend to be more friendly, talkative, and energetic.
Those who score low are usually introverts who prefer spending time alone or with a small group of close friends.
If you love attending parties, making new friends and are often the one to start conversations, you are most likely an extravert.
If you have this personality trait, you might be good at networking and excel in careers requiring social interaction, like sales or event planning.
People with higher extraversion scores often report higher job satisfaction when their work involves social interaction and teamwork. However, those who lean more towards introversion tend to be more content when they have jobs that allow for independent tasks and fewer social demands.
Here’s a list of careers that are well-suited for individuals with extraverted personalities:
- Sales representative: Extraverts are often natural salespeople with outgoing and persuasive communication skills.
- Marketing manager: Engaging with clients, teams, and audiences is crucial in marketing, and extroverts thrive in this dynamic environment.
- Public relations specialist: Building and maintaining relationships with the public, media, and stakeholders requires strong social skills.
- Service or hospitality sector: Talking to customers all day requires fortitude, and these individuals are the right fit.
Those who are more agreeable are more likely to be empathetic and find pleasure in helping others and working with people who need more help.
2. Agreeableness
If you score high in agreeableness, you tend to be more cooperative, compassionate, and considerate of others’ feelings.
While those who score low might be more competitive and straightforward, focusing on their goals and being less concerned about pleasing everyone.
These people are always willing to help, are great listeners, and often go out of their way to make others feel comfortable. Here are the best career paths for those who are agreeable:
- Nursing and healthcare: The healthcare field benefits greatly from agreeable individuals who can provide compassionate patient care.
- Social worker: Social workers help people in need, and their empathetic and supportive nature is essential for this role.
- Counsellor: These professions rely on creating a safe and supportive environment for clients, where understanding and empathy are key.
- Education: No matter at what age, children need guidance and care while learning, and teachers are in the perfect position to offer a holistic education for them.
Those who score high for conscientiousness tend to do well in careers as project managers as they are organised, reliable and detail-oriented.
3. Conscientiousness
Conscientiousness is defined by high levels of thoughtfulness, good impulse control and goal-directed behaviours.
If you score high in conscientiousness, you tend to be organised, reliable, and detail-oriented. You may enjoy planning ahead and always consider how your behaviour affects others.
On the other hand, if your score is lower, you might be more flexible and spontaneous, with a tendency to prefer a less structured lifestyle.
Here’s a list of careers that are well-suited for individuals with a conscientious personality:
- Accountant: Attention to detail and a strong work ethic are essential in accounting and auditing.
- Project manager: Conscientious individuals excel at planning, organising, and overseeing complex projects.
- Data analyst: Analysing and interpreting data accurately and efficiently requires precision and thoroughness.
- Engineering: Working with delicate systems requires intense focus and skill.

4. Neuroticism
Neuroticism is one of the Big Five Personality Traits that is characterised by sadness, moodiness, and emotional instability. People with high neuroticism tend to experience mood swings, anxiety, irritability and sadness.
If you have a lower neuroticism score, you are generally more emotionally stable and better at handling stress.
Someone with a high neuroticism score tends to get anxious before exams or important presentations and often worries about what might go wrong. These people might find their calling in careers that benefit from their sensitivity, such as psychology or counselling, where empathy and understanding can make a substantial difference.
If you score high for neuroticism, the best careers for you include:
- Freelance work: Freelancers can set their schedules and work environments, providing flexibility to manage their emotional needs.
- Creative Professions: Careers in art, writing, or music can offer an outlet for emotional expression.
- Counsellor: Some individuals with high neuroticism choose careers in mental health to better understand and manage their own emotional challenges while helping others.
- Animal care: Animals are great because they don’t talk back, and they offer comfort in ways humans sometimes cannot.
5. Openness
Openness is one of the Big Five Personality Traits that describes someone who is curious, creative and willing to embrace new experiences.
If you score high in openness, you’re likely imaginative and eager to explore new ideas and concepts. However, you may lean towards practicality and familiarity if you have a lower score.
If you are someone who is enthusiastic about trying new things, whether travelling to foreign countries, experimenting with different art forms, or engaging in philosophical discussions, you might be well-suited for careers in creative fields like graphic design, journalism, or research.
Studies also found that you’re likely to be fulfilled in roles that encourage creative thinking and exploration, while those with lower scores may thrive in roles that demand routine and established procedures.
Scored highly for openness? Your life’s calling could be one of the following careers:
- Artist: Creative and imaginative individuals often thrive in artistic pursuits like painting, sculpture, or design.
- Writer: Authors and poets can channel their love for new ideas and words into captivating stories and prose.
- Research scientist: The scientific community benefits from those who question the unknown and pursue groundbreaking discoveries.
- Software developer: With so many new technological advancements in the past couple of years, the field needs people who are open to these new changes.
Frequently asked questions about the Big Five Personality Traits
What is the most common trait?
The most stable trait is conscientiousness, as it tends to increase as we age and remain relatively stable throughout adulthood.
Naturally, our conscientious behaviours — such as discipline, responsibility, and organisation — are reinforced by our life experiences, work, and social expectations.
As people grow older, they tend to become more reliable and goal-oriented, making this trait more stable compared to others like extraversion or neuroticism, which may fluctuate based on life circumstances.
What is the rarest personality trait?
Surprisingly, one of the rarest traits to have a high score is openness to experience.
Most people tend to fall somewhere in the middle, but extreme openness is rare. It’s linked to traits like creativity, intellectual curiosity, and a strong desire for novelty, which can sometimes lead to unconventional or non-conformist lifestyles.
In many societies, cultural norms and traditional structures favour a balance between openness and practicality, making extreme openness less common.
Seems simple, but don’t underestimate how powerful the Big Five Personality Traits are in today’s world — and in your world too.
How do other personality quizzes such as the Myers-Briggs Type Indicator (MBTI) fare in comparison?
| Feature | The Big Five (OCEAN) | Myers-Briggs Type Indicator (MBTI) |
|---|---|---|
| Scientific Backing | High: Grounded in decades of factor analysis and peer-reviewed research. | Low: Viewed by many academic psychologists as a descriptive tool rather than a predictive one. |
| Measurement Style | Continuous spectrum: Scores you on a sliding scale for each trait (e.g., 75th percentile in Extraversion). | Binary boxes: Sorts individuals into 1 of 16 distinct types (e.g., INTJ). |
| Key Dimensions | Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (Emotional Stability). | Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving (lacks Neuroticism). |
The Enneagram test is also not considered as scientific as the Big Five Personality Traits either, as it isn’t strictly evidence-based. While Enneagram and MBTIs are widely used for personal growth, they lack robust scientific validation. Critics categorise these personality tests as pseudoscience because their types cannot be empirically measured or tested in the same way as standard, evidence-backed personality models
