ISTPs are the most unpredictable of the 16 personality types, because they're typically rational and logical, but can also be enthusiastic and spontaneous.
#15 – The ISTJ
According to the MBTI® Manual, ISTJs ranked highly on conforming to rules, seldom getting in trouble, suppressing hostile feelings, and appreciating convention and well-organized, predictable situations.
The short answer: INFJ (Introverted-Intuitive-Feeling-Judgment) is the most complex Myers-Briggs Personality Type.
Out of the IN personality types, INFPs and INTPs struggle the most with indecisiveness. These types can see endless possibilities, which makes it difficult for them to gain the closure they need to move forward. INPs may struggle to identify a strong sense of purpose and direction.
The most rebellious personality types include the ENTP, INTP, ESTP, and ISTP, while some of the least rebellious are the ISFJ, ESFJ, ESTJ, and ISTJ.
According to the MBTI® Manual ENTJs are the type least likely to suppress anger and least likely to show anger.
INFJ is the rarest personality type across the population, occurring in just 2% of the population. It is also the rarest personality type among men. INFJ stands for Introversion, Intuition, Feeling, and Judging. This unique combination is hard to find in most people.
In fact, there was a pretty decisive split in the responses among these personality types. Turbulent Mediators (INFP-T) and Turbulent Adventurers (ISFP-T) are the most likely types to give up on challenging tasks, with 53% and 54% agreeing respectively.
The INFP may be the toughest personality type of all for others to understand. They are seemingly easy-going and carefree, but when it comes to their values, they can become suddenly uncompromising. They're friendly to a fault, but they frequently find others hard to be around.
"While the INTJ personality type is known for being highly intelligent, they also score high on trustworthiness, probably because they are self-aware enough to recognize the importance of trust in human relationships," Parmar explains.
The ISFP – Being Their Own Worst Critic
ISFPs may seem easy-going at first glance, but these types actually hold themselves to very specific standards. They are drawn towards creativity and a life of meaning, but they often struggle to understand the steps needed to accomplish their goals.
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.
The INFJ. The INFJ is one of the rarest and most misunderstood personality types. These types are often seen as mysterious, daydreamy, and even confusing.
ENTJ. Of all the personality types, ENTJs are arguably the ones who care least about other people's opinions of them. This is not a personality type who sugarcoats things or cares what others think of them. They are decisive, assertive and extremely blunt.
ISTP: logical pragmatists
Who they are: These are direct, to-the-point characters, who are loyal to their peers but not overly concerned with laws and rules. ISTPs are the most unpredictable of the 16 personality types, because they're typically rational and logical, but can also be enthusiastic and spontaneous.
ESFJ. Those who are extroverted, sensing, feeling, and judging are often identified as one of the kindest types by experts. "ESFJs have extroverted feeling as a dominant cognitive function," Gonzalez-Berrios says. "This makes them rule by their hearts.
INFP and INFJ: The Overthinkers
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.
ISTJ. Quiet, serious, earn success by thoroughness and dependability. Practical, matter-of-fact, realistic, and responsible. Decide logically what should be done and work toward it steadily, regardless of distractions.
Additionally, immature ISFPs may become highly sensitive to criticism and take everything personally. Instead of balancing their feeling and thinking sides, these ISFPs tend to believe that whatever they feel is the ultimate truth.
The ENFP. You'll never give up because you nearly always see alternatives, possibilities, and potential in the world.
The least common Myers-Briggs personality Type is INFJ
There are only slightly more female INFJs than male INFJs though, with 1.6% of the women in the US having this preference and only 1.3% of the men in the US population having this preference.
Immature personality disorder (IPD) was a type of personality disorder diagnosis. It is characterized by lack of emotional development, low tolerance of stress and anxiety, inability to accept personal responsibility, and reliance on age-inappropriate defense mechanisms.
People with an Enneagram Type 1 personality tend to be rational, principled, and judicial in their behavior. They usually have a desire for justice and equality. They are motivated by a strong sense of right and wrong.
INFJ is regarded as the most sensitive personality type. Some estimates suggest that 80 to 90% of people who test as INFJs also test as highly sensitive people, because the traits of the two overlap so much.
