Unpacking the idea of a 'most common' Big Five personality type

The Big Five personality assessment, also known as the five-factor model, is widely considered the most scientifically validated framework for understanding personality. It describes personality across five broad dimensions: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (often remembered by the OCEAN or CANOE acronym). But with such a comprehensive model, a natural question arises: is there a “most common” Big Five personality type?

While it’s tempting to seek a single, predominant type, the reality of personality distribution is far more nuanced. Unlike discrete categories, personality traits exist on a spectrum, and most people fall somewhere in the middle of each dimension, rather than at extreme ends. This article will delve into what research says about the distribution of Big Five traits and why the idea of a single “most common” type can be misleading.

The Big Five traits: a brief overview

Before exploring commonality, it’s essential to understand what each of the Big Five traits represents:

Trait	High scorer	Low scorer
Openness to Experience	Creative, curious, drawn to novelty and ideas	Prefers routine, practical, conventional
Conscientiousness	Organized, disciplined, goal-oriented, careful	Spontaneous, flexible, less structured
Extraversion	Sociable, assertive, energized by interaction	Introverted, reflective, prefers solitude
Agreeableness	Compassionate, cooperative, trusting, warm	Competitive, skeptical, more direct
Neuroticism	Prone to anxiety, emotional volatility, worry	Calm, resilient, emotionally stable

• Openness to Experience: Reflects a person’s receptiveness to new ideas, imagination, curiosity, and appreciation for art, emotion, adventure, and unusual ideas. High scorers are often creative and intellectual, while low scorers prefer routine and tradition.
• Conscientiousness: Describes a person’s tendency to be organized, disciplined, responsible, and goal-oriented. High scorers are typically efficient and careful, while low scorers might be more spontaneous and less structured.
• Extraversion: Characterizes an individual’s energy, sociability, assertiveness, and emotional expressiveness. Extraverts gain energy from social interaction, while introverts (low scorers) prefer solitude and find social situations draining.
• Agreeableness: Pertains to a person’s tendency to be compassionate, cooperative, empathetic, and trusting. High scorers are often perceived as warm and friendly, while low scorers can be more competitive and skeptical.
• Neuroticism: Measures emotional stability and the tendency to experience negative emotions like anxiety, anger, or depression. High scorers are prone to emotional volatility, while low scorers are generally calm and resilient.

These five traits are generally considered orthogonal, meaning they are largely independent of each other. This independence means that a person can be high in Extraversion and low in Conscientiousness, for example, without one influencing the other in a predictable way. This independence is a key reason why defining a single “most common type” is challenging.

Why “most common type” is a complex question

When we think about what’s “common,” we often refer to statistical averages or modes within a population. For personality traits, the distribution across a large population typically follows a normal distribution (a bell curve). This means that most people score in the middle range for each trait, with fewer people scoring at the extreme high or low ends. Therefore, the most “common” individual Big Five profile would likely be someone who scores moderately on all five traits.

However, this statistical average doesn’t equate to a distinct “type” in the way that popular personality frameworks sometimes suggest. The combination of five independent dimensions, each with a continuous spectrum of scores, results in an immense number of possible unique profiles. For instance, a study by Gerlach et al. (2018) Gerlach et al. (2018) attempted to identify personality types from Big Five data using clustering algorithms. They identified four main types: “Average,” “Reserved,” “Role Model,” and “Self-Centered.” The “Average” type was indeed the most prevalent, characterized by high Neuroticism and Extraversion, but low Openness. This finding, while interesting, still represents a statistical cluster rather than a prescriptive “type” that everyone must fit into.

“We identified four robust personality types — Average, Reserved, Role Model, and Self-Centered — with the Average type being the most common, but these clusters should be seen as probabilistic groupings, not rigid boxes.” — Gerlach et al., Nature Human Behaviour, 2018

Furthermore, what is considered “common” can vary significantly across cultures and demographics. Research has shown that average trait levels can differ between countries. For example, some studies suggest that collectivistic cultures might score lower on Extraversion and higher on Agreeableness compared to individualistic cultures McCrae & Terracciano (2005). These cultural nuances make a universal “most common type” even more elusive.

Average trait levels vs. a dominant type

Instead of a single dominant “type,” it’s more accurate to discuss average trait levels within a population. Generally, when looking at large-scale population data, the average person tends to score moderately on all Big Five dimensions. This means they are not extremely introverted or extraverted, not exceptionally conscientious or disorganized, and so on. This moderate scoring is what makes the “Average” cluster identified by Gerlach et al. (2018) the most populated.

However, even within these averages, there’s tremendous individual variation. Two people could both score “average” on all five traits but still have unique life experiences, motivations, and behaviors. The power of the Big Five lies in its ability to describe these individual differences accurately, rather than categorizing people into rigid boxes.

Understanding the distribution of traits helps us appreciate the diversity of human personality. It highlights that while certain trait levels might be more statistically frequent, this doesn’t diminish the validity or value of less common profiles. Each unique combination of Big Five scores contributes to the rich tapestry of human experience and potential.

Ultimately, the quest for a “most common” Big Five personality type often overlooks the fundamental nature of personality: its continuous, multidimensional, and highly individualistic qualities. Rather than seeking to fit into a common mold, the value lies in understanding your unique blend of traits and how they influence your life and career choices. The Big Five provides a robust framework for this self-discovery.
