Unveiling the Least Common Personality Type

Alt Text

First, we introduce the least common personality type, the INFJ, also referred to as the ‘Advocate’ or the ‘Idealist.’ INFJs make up only 1% to 3% of the U.S. population, with a specific prevalence of 2.3% in the general population. This rarity is not a constraint but rather a testament to their distinct personality traits that set them apart in a crowd.

INFJs are characterized by a unique blend of qualities that make them stand out. They embody a rare combination of empathy, intuition, and sensitivity, coupled with a strong sense of judgment. This enables them to perceive possibilities that others might miss and approach life in a structured and organized way. However, their rareness often poses challenges, as their unique perspective might not be easily recognized by others. INFJs tend to navigate these challenges with grace and determination.

The Rarity Factor

So, what factors contribute to the rarity of the INFJ personality type? The answer lies in the percentage of the general population that prefers this personality type. The INFJ personality type is one of the rarest, comprising only 1.5% of the general population, which is less common than ENTJ at 1.8% and ENFJ at 2.2%.

In contrast, the ESFJ personality type makes up a much larger portion of the population, accounting for 5.7% of the national sample.

Gender Differences

Gender distribution significantly influences the prevalence of certain personality types. For instance, while 3.3% of men prefer the INTJ personality type, only 0.8% of women do, indicating a stronger prevalence among males. The rarest female MBTI type is ENTJ, comprising 1.5% of the female population. Interestingly, when it comes to the rarest MBTI type overall, the numbers may vary depending on various factors.

The INFJ personality type, however, shows a nearly equal distribution between genders in the US, being 1.6% women and 1.3% men. This balanced distribution is quite interesting, as over 56% of females test as J types on the Myers-Briggs Type Indicator, suggesting a feminine skew for this preference. This distribution could be attributed to the INFJ’s preference for intuition and feeling, which is less common among men, potentially affecting the gender distribution of this rare personality type.

The Power of Intuition and Judging

Alt Text

The INFJ personality type hinges on two integral components: intuition and judging. These individuals possess a strong intuition and judging preference, which sets them apart from other personality types. However, this unique blend of traits often leads INFJs to struggle with society’s tendency to favor extroverted sensing (Se) types, which contrasts with their introverted intuition (Ni) dominant trait.

Intuitive Thinking

INFJs, famous for their intuitive thinking, exhibit a dominant function of introverted intuition coupled with an auxiliary function of extraverted feeling. This strong sense of intuition allows them to pick up on subtle cues and patterns, contributing to their unique perspective. To effectively apply their intuition to judgment, however, they need to thoroughly understand the ideas and situations at hand.

NT personality types including INTJs, INTPs, ENTPs, and ENTJs are known for their innovative mindset, focusing on new ways to address tasks and often seeking change in leadership roles to improve situations. This innovative approach can lead to inventive solutions. However, INFJs may struggle with verbalizing their intuitive insights as effectively as expressing them in writing, posing a challenge in communicating their visions and ideas.

Judging Preference

The INFJ’s judging preference significantly complements their intuitive insights, making it a prominent facet of their personality. The Judging (J) preference in the Myers-Briggs typology includes being systematic, planful, and methodical, which is linked to the Big Five’s Orderliness aspect. Individuals with a strong judging preference focus on planning and organization, enabling them to approach life in a structured manner.

For individuals with the rarest personality types, it’s imperative to augment their intuitive insights with their judgment preferences rather than dismiss them prematurely. This balanced approach prevents them from limiting their perspectives and allows them to draw on the full strength of their unique personality traits.

Strengths and Challenges of the Least Common Personality Type

Alt Text

The least common personality type, which can also be referred to as a psychological type, presents a distinct combination of strengths and challenges. Individuals with this type often showcase a natural ability for strategic thinking and long-term planning. They are typically driven, ambitious, and have a high level of self-motivation. However, they often face challenges in feeling misunderstood and finding like-minded peers.


INFJs are distinguished by a combination of:

  • Compassion
  • Idealism
  • Organizational skills
  • Creative imagination
  • Versatile, morally-guided decision-making
  • Warm hearted

Their unwavering drive towards meaningful goals, self sacrifice, and detail oriented approach sets INFJs apart in their quest for significant achievements.

Moreover, the INFJs’ innate ability to absorb and reflect emotions, coupled with their deep insightfulness and empathy, enhances their interpersonal relationships. This ability empowers them to:

  • Forge empathetic environments
  • Create a safe space for others to express their emotions
  • Understand and validate the feelings of others
  • Provide support and guidance to those in need
  • These qualities further set them apart from other personality types.


Despite their strengths, INFJs face a set of unique challenges. They crave authenticity and meaningful relationships, which can be challenging to find. This quest often leads to a sense of rarity and difficulty in forming connections. As they often feel misunderstood, this contributes to their sense of isolation due to their complex nature.

Further, INFJs’ high emotional sensitivity makes them vulnerable to emotional exhaustion as they often absorb the emotions of others. Also, their tendency towards perfectionism and unrealistically high standards for themselves and others can lead to internal challenges.

Careers and Relationships for the Least Common Personality Type

The distinct traits of the INFJ personality type have a significant impact on their career choices and relationship dynamics. They often excel in careers that require innovation and problem-solving, and they value deep, meaningful relationships.

Career Opportunities

INFJs find great satisfaction in careers that align with their unique traits. Some careers that are particularly rewarding for INFJs include:

  • Health care roles such as Physical Therapist, Public Health Educator, or Psychiatrist
  • Counseling positions like Licensed Clinical Psychologist, Social Worker, and mental health professionals
  • Scientific careers, particularly roles such as Social Scientist, Genealogist, or Environmental Scientist

These careers allow INFJs to engage with social issues and contribute positively to society.

Furthermore, INFJs excel in roles that require creativity and innovation. They thrive in roles such as:

  • Coaches
  • Writers
  • Marketers
  • Public speakers

INFJs leverage their understanding of psychology and their skill with words in these roles. Entrepreneurship also provides INFJs with the freedom and creativity they crave, allowing them to work passionately across various activities such as writing, speaking, coaching, teaching, and consulting.

Overall, the wide spectrum of career paths available to INFJs underscores the versatility and adaptability of this rare personality type.

Relationship Dynamics

In relationships, INFJs thrive in environments that demonstrate authenticity, active listening, and healthy communication strategies. They value being heard and understood, which aligns with their need for deep, meaningful connections. This desire for authenticity and depth often leads to a sense of rarity and difficulty in forming connections, contributing to their feeling of being misunderstood.

INFJs appreciate being with a partner who:

  • Shares a similar value system
  • Possesses an ability to intuitively understand their thoughts and feelings
  • Is equally committed to personal growth and development
  • Values evolution and progress within themselves and their relationships.

However, relationships between INFJs can suffer if both have the same weaknesses and expect the other to compensate, particularly in practical matters like finances or household management. Therefore, to maintain a healthy relationship dynamic, INFJs need to communicate openly, express their feelings freely, and establish boundaries that respect their need for independence and alone time.

Comparing the Least Common Personality Type to Other MBTI Types

Although the INFJ personality type is unique, it shares some core functions with other MBTI types. These shared functions form a foundation for shared understanding and interaction among different personality types. However, the INFJ also possesses distinct traits that set it apart from other types, such as a high level of intuition combined with judging qualities.


All Myers-Briggs personality types exhibit certain cognitive functions, though they manifest in varying orders and intensities. Understanding your Myers Briggs personality type can help you better navigate these differences. Taking the Myers Briggs test is a great way to discover your personality type. While different personality types may prioritize different cognitive functions, there is overlap in how these functions are expressed. This overlapping of cognitive functions can create a foundation for shared understanding and interaction between different personality types.

Shared values, such as a drive for autonomy or a passion for social justice, can further link disparate types. The presence of similar cognitive functions and shared interests and values provides opportunities for collaboration across different Myers-Briggs types.


Despite these shared features, INFJs harbor unique traits that distinguish them from the majority of the population. They are often seen as walking contradictions, such as being easy-going perfectionists and both creative and analytical. Their complex personality profiles include a blend of empathy, intuition, and sensitivity, setting them apart from most of the population.

Furthermore, INFJs are known for their ‘all-or-nothing’ approach to life, showing an intense passion for their interests that sets them apart from other personality types with a more balanced approach. Their excellence in written communication also distinguishes them from more extroverted and verbally articulate personality types.
