Ever wondered why, despite people’s differences, they can connect with someone new instantly? Almost as if they’ve been friends forever? That’s because of their personality types.
Personality types influence not only personal aspects of our lives but also our work styles, habits, and interpersonal relationships with our colleagues.
Many Fortune 500 companies use the Myers-Briggs Type Indicator (MBTI) to identify traits of people’s personalities for leadership development purposes, conflict prevention, and recruitment.
The MBTI is a self-reported questionnaire that categorizes people into 16 different personality types by assessing their personality using four specific dichotomies: Introversion vs. Extroversion, Sensing vs. Intuition, Thinking vs. Feeling, and Judging vs. Perceiving.
Answer a given set of questions on a free online personality test and the MBTI will assign you a four-letter code based on your preferences in each category (e.g., ENFP, ISTJ, INTJ, INFJ).
INFJ and INTJ are considered to be among the world’s top three rarest personality types! Read on to explore these personality types, identify their dynamics and compatibility, and discover tools that can help organizations manage different personalities productively!
If you’re curious about the MBTI test and think you’re either INTJ or INFJ, here’s a quick gist of these unique personality types:
| Feature | INTJ (The Architect) | INFJ (The Advocate) |
| Dominant function | Introverted thinking (Ti) | Introverted intuition (Ni) |
| Focus | Logic, systems, efficiency | Values, meaning, long-term vision |
| Decision-making | Objective, analytical, focused on outcomes | Value-driven, considers their impact on others |
| Social interaction | Enjoy deep conversations but need alone time to recharge | Can be outwardly warm but require solitude to process emotions |
| Strengths | Strategic, independent, problem-solvers | Insightful, empathetic, idealistic |
| Weaknesses | Can be perceived as cold or insensitive | May struggle with criticism or conflict |
Modern society often rewards extroversion and assertiveness, which might be why INTJs and INFJs are rarer. Let’s dive deeper into what makes both these personalities tick!

INTJs and INFJs, both considered rare personality types within the Myers-Briggs framework, share some core traits but differ in how they use them. Here’s a breakdown of their similarities and differences:
You might think that since these two personality types have three letters in common, they aren’t going to be that different. Well, get ready to be surprised!
INTJs are the quintessential analytical minds. They dissect information with surgical precision, prioritizing cold, hard facts and objective data.
Emotions are seen as a potential distraction, and decisions are made based on what logic dictates and what will lead to the most efficient and successful outcome.
INFJs, on the other hand, consider logic and emotion in their decision-making process.
While they value facts and analysis, their core motivation lies in understanding the human element. They strive for win-win solutions that benefit everyone involved, fostering harmony and positive outcomes.
INTJs are drawn to systems, efficiency, and strategic planning. They relish the challenge of optimizing processes, identifying the most effective course of action, and achieving clearly defined goals.
INFJs are more interested in understanding the deeper meaning behind things. They’re natural empaths, seeking to create positive change and build a sense of connection.
INTJs’ laser focus on logic and efficiency can sometimes come across as cold or insensitive. They may struggle with small talk, finding it tedious and unproductive.
INFJs radiate warmth and empathy, making them excellent communicators and relationship builders. They can navigate complex emotional undercurrents with grace and understanding.
While their logical power is undeniable, INTJs may struggle to consider the emotional aspects of situations. Their focus on efficiency can make them inflexible and resist changes in plans.
INFJs’ sensitivity to the emotions of others can be a double-edged sword. They’re prone to burnout from constantly being aware and accommodating of the emotions of those around them.
While INTJs and INFJs have distinct approaches to decision-making and social interaction, their underlying cognitive functions lead to some shared strengths.
Here’s a deeper look at the similarities that bring these two unique personality types together:
Both INTJs and INFJs have the power of introverted thinking. They’re introspective souls who crave solitude to process thoughts and emotions.
Spending time by themselves allows them to delve into their inner world, analyze information meticulously, and formulate well-thought-out plans.
This introspective nature fosters a depth of understanding, making them insightful observers of the world around them.
Both these personality types are drawn to understanding the ‘why’ behind things. They excel at seeing the big picture, identifying patterns, and contemplating future possibilities.
This visionary thinking allows them to develop long-term strategies, anticipate potential problems, and create innovative solutions with a clear understanding of the desired outcome.
Neither INTJs nor INFJs shy away from working independently. They’re comfortable taking ownership of projects, trusting their judgment, and making decisions without constant validation.
This self-reliance allows them to excel in tasks that require focus, concentration, and the ability to think critically without external pressure.
While their social styles may differ, both INTJs and INFJs form deep and meaningful connections with those they trust.
They’re fiercely loyal and protective of their friends, family, and colleagues, offering unwavering support and dedication to those they hold close.
These MBTI types can arrive at innovative solutions to problems and achieve meaningful outcomes when working together.
