By Dr. Edwin van Thiel, updated April 7, 2022

Why do people respond differently to the same situations? In contemporary psychology, the Big Five personality traits are five broad domains which define human personality and account for individual differences. This article tells you more about the Big Five personality theory and the personality traits it distinguishes. After reading it, take our free personality test to determine your own Big Five personality type.

History of Big Five personality theory

Several independent sets of researchers discovered and defined the five broad personality traits based on empirical, data-driven research. Ernest Tupes and Raymond Christal advanced the initial model, based on work done at the U.S. Air Force Personnel Laboratory in the late 1950s.1 J.M. Digman proposed his five factor model of personality in 19902, and Goldberg extended it to the highest level of organizations in 1993.3 In a personality test, the Five Factor Model or FFM4 and the Global Factors of personality5 may also be used to reference the Big Five traits.

Human resources professionals often use the Big Five personality traits dimensions to help place employees. That is because these dimensions are considered to be the underlying traits that make up an individual’s overall personality.

The Big Five personality traits are:

  • Openness
  • Conscientiousness
  • Extraversion
  • Agreeableness
  • Neuroticism

or OCEAN:

  • Openness - People who like to learn new things and enjoy new experiences usually score high in openness. Openness includes personality traits like being insightful and imaginative and having a wide variety of interests.
  • Conscientiousness - People that have a high degree of conscientiousness are reliable and prompt. Personality traits include being organized, methodic, and thorough.
  • Extraversion - Extraverts get their energy from interacting with others, while introverts get their energy from within themselves. Extraversion includes the personality traits of energetic, talkative, and assertive.
  • Agreeableness - These individuals are friendly, cooperative, and compassionate. People with low agreeableness may be more distant. Personality traits include being kind, affectionate, and sympathetic.
  • Neuroticism - Neuroticism is also sometimes called Emotional Stability. This dimension relates to one’s emotional stability and degree of negative emotions. People that score high on neuroticism often experience emotional instability and negative emotions. Personality traits include being moody and tense for example.

Q. What personality traits does this Big Five test measure?

A. The Big Five personality test measures the five personality factors that psychologists have determined are core to our personality makeup. The Five Factors of personality are:

  • Openness - How open a person is to new ideas and experiences
  • Conscientiousness - How goal-directed, persistent, and organized a person is
  • Extraversion - How much a person is energized by the outside world
  • Agreeableness - How much a person puts others' interests and needs ahead of their own
  • Neuroticism - How sensitive a person is to stress and negative emotional triggers

The Big Five model of personality is widely considered to be the most scientifically robust way to describe personality differences. It is the basis of most modern personality research.

Q. What is the difference between Big Five, Five Factor, and the OCEAN model of personality?

A. Big Five, Five Factor, and OCEAN are all ways of describing the same theory of personality. Multiple psychological studies have arrived at the conclusion that the differences between people's personalities can be organized into five broad categories, called the Big Five or Five Factors. These are sometimes referred to as the five broad dimensions of personality.

The differences between people’s personalities can be broken down in terms of five major traits—often called the “Big Five.” Each one reflects a key part of how a person thinks, feels, and behaves. The Big Five traits are:

Individual personalities are thought to feature each of these five broad traits to some degree. When the traits are measured, some people rate higher and others rate lower: Someone can be more conscientious and less agreeable than most people, for instance, while scoring about average on the other traits. These traits remain fairly stable during adulthood.

People can also differ on the more specific facets that make up each of the Big Five traits. A relatively extroverted person might be highly sociable but not especially assertive.

The five-factor model is widely used by personality researchers, but it is not the only model. A more recently introduced six-factor model known as HEXACO adds the factor of honesty-humility to the original five traits.

The Big Five traits are typically assessed using one of multiple questionnaires. While these tests vary in the exact terms they use for each trait, they essentially cover the same broad dimensions, providing high-to-low scores on each: openness to experience (also called open-mindedness or just openness), conscientiousness, extroversion (the reverse of which is introversion), agreeableness, and neuroticism (sometimes negative emotionality or emotional stability).

One test, the latest version of the Big Five Inventory, asks how much a person agrees or disagrees that he or she is someone who exemplifies various specific statements, such as:

  • “Is curious about many different things” (for openness, or open-mindedness)
  • “Is systematic, likes to keep things in order” (for conscientiousness)
  • “Is outgoing, sociable” (for extroversion)
  • “Is compassionate, has a soft heart” (for agreeableness)
  • “Is moody, has up and down mood swings” (for neuroticism, or negative emotionality)

Based on a person’s ratings for dozens of these statements (or fewer, for other tests), an average score can be calculated for each of the five traits.

The five-factor model not only helps people better understand how they compare to others and to put names to their characteristics. It’s also used to explore relationships between personality and many other life indicators. These include consequential outcomes such as physical health and well-being as well as success in social, academic, and professional contexts. Personality psychologists have observed reliable associations between how people rate on trait scales and how they fare or feel, on average, in various aspects of their lives.

Various ways of representing major traits have been proposed, and personality researchers continue to disagree on the number of distinct characteristics that can be measured. The five-factor model dominates the rest, as far as psychologists are concerned, although multiple types of assessments exist to measure the five traits.

Outside of academic psychology, tests that aim to sort people into personality types—including the Myers-Briggs/MBTI and Enneagram—are highly popular, though many experts take issue with such tests on scientific grounds. The five-factor model has conceptual and empirical strengths that others lack.
