Probably the best that can be said is that it is easiest to make the case for the INFP, INTP, or ISTP as the most introverted personality type.
Of all of the introvert personality types on the MBTI, the INTP tends to be the most introverted. They tend to be thoughtful, quiet, and very reserved around others.
1. INTP. The winner of the most introverted personality type goes to INTPs. These analytical thinkers are often deep in thought and prefer to explore complex problems independently.
INTJs are typically very quiet and reserved unless they happen to meet someone who, like them, loves exploring theoretical concepts, analyzing possibilities, and dreaming up long-term goals. That said, they're not typically very verbal when it comes to discussing their feelings or people's personal lives.
INFP: The shiest ones.
"ESFJs are social creatures with a lot of love for routine. They tend to be sensitive and feel most awkward when they think they are the butt of someone's joke or are not having their feelings in a friendship or relationship reciprocated," says Owens.
ENFP. When it comes to physical attractiveness, ENFPs lead the pack.
Introverts claim to dread it, intuitives admit they abhor it, thinkers find it pointless, and perceivers believe it's excessive. In fact, the more we analyze the concept of small talk, the more it seems that most people inherently dislike it.
When you hear the word introvert, you might think of someone who's shy or quiet and prefers to be alone. While that may be true for some introverts, there's much more to this personality type.
INTJ – (Introvert, Intuitive, Thinking, and Judging). The Mastermind. Other nicknames for the INTJ include The Conceptual Planner or The Architect. Arguably the smartest MBTI type.
INTJ. Much like their extroverted counterparts, INTJs are also known for their self-assurance—and it's actually this introverted intuition that contributes to their confidence.
The classic type of introvert we all know. A social introvert is someone who categorically prefers to spend time alone. They will go out of their way to ensure that they have the amount of time to themselves that they need. But if they do socialise, it will only be with a very close-knit group of friends.
ENFJs are known for searching for the goodness in others, and for being able to summon a powerful level of compassion, which means that even when their partner falls short, their acceptance and love is still unwavering. Expressive, nurturing, and supportive, ENFJs love hard because it's the only way they know how.
The third most rare Myers-Briggs personality type is INTJ
ENTJ (0.9%) and INTJ (0.8%) are the least common MBTI personality types for women. Among men in the US, INFJ (1.3%) and ENFJ (1.6%) are the least common MBTI personality types.
INFPs and ISFJs are the cutest types. They both possess a natural sweetness and affection that makes them hard to resist. INFPs and ISFJs are both empathetic and caring, which can be very cute. Plus, they tend to have an air of innocence that makes them hard not to love.
ENFJ (The Protagonist)
This personality type's outgoing nature and empathy makes them a formidable flirt. They're very tuned in to other people's emotions and needs, and they can use this to their flirtatious advantage by making whoever they are chatting up feel truly seen.
We start off with INFPs and INFJs: two Introverted personalities that often experience bouts of anxiety. When it comes to these types, their anxiety can stem from an inclination to overthinking.
Type D personality is associated with social anxiety in the general population.
INTJs are often misunderstood simply because there are so few of them around. Making up only 2.1% of the US population, they understand the world in a fundamentally different way than most other types. While the rest of the world looks first to tangible data, INTJs follow symbols and underlying meanings first.
One person's social interactions might cause them to lean toward the INFP as the most introverted personality type, while someone else might know an INTP who they swear is the most introverted person they've ever known.
ENTJs and ESTJs feel insecure when they have to tune into their own individual values and emotions. They prefer to work with tangible, provable facts and logic. They tend to put aside their own individual feelings and instead focus on objective data and truths that can be applied to all situations.
The least confident personality type is INFPs. INFPs are imaginative and creative people who put their hearts into whatever they do. They trust in their own internal values, beliefs, and opinions which gives them the assurance to make decisions that align with what they believe in.
