It has long been believed that people can't change their personalities, which are largely stable and inherited. But a review of recent research in personality science points to the possibility that personality traits can change through persistent intervention and major life events.
According to most personality type theories, the individual's type is inborn and does not change. However, individuals can develop traits and habits that differ or even directly contradict the description of their type.
Overall, the rarest personality type is INFJ
The rarest personality type is the INFJ personality type, known as 'The Counselor'. 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.
Personality changes can be caused by a mental illness like depression, bipolar disorder, or personality disorders. It may also be caused by physical illnesses like a urinary tract infection (especially in older adults), concussion, or brain tumor. Understanding the cause can help create an effective treatment.
Dissociative Identity Disorder (Multiple Personality Disorder) A mental health condition, people with dissociative identity disorder (DID) have two or more separate personalities. These identities control a person's behavior at different times.
All of this is to say that if you have received differing reported MBTI letters, it could mean that you have significant distinct tendencies on both sides of one or more preference pairs (E/I, S/N, T/F, J/P). However, according to the theory behind the MBTI, you're ultimately one or the other in each pair.
ISFPs are quiet, reserved types who like to focus their attention on people and the experiences they enjoy. They aren't typically big talkers unless someone they're talking about something deeply important to them or they're trying to empathize verbally with someone.
We all know that anxiety affects our emotional state and makes interacting with the world difficult, but what may be less obvious is how it changes what we focus our attention on throughout the day. By biasing attention, anxiety alters what we are conscious of, and in turn, the way we experience reality.
The most prominent symptoms of MDD include a severe and persistent low mood, profound sadness, or a sense of despair. The way depression affects the brain can directly result in personality changes.
People can also change their personality based on who they're around. If the person you're with makes you uncomfortable, you're not likely to be very talkative and offer up good conversation. However, if you're on the phone with a friend you haven't talked to for awhile, you're likely to have an animated conversation.
ISTP - Introverted, Sensing, Thinking, And Perceiving
People with the ISTP personality type are often described as hard to read.
Overall, the most common personality type is ISFJ
It is also the most common personality type among women. ISFJ stands for Introversion, Sensing, Feeling and Judging. This combination of traits means that people with the ISFJ personality type tend to be compassionate, caring and conventional.
The most rare Personality Types are INFJ, followed by ENTJ and INTJ.
While childhood trauma won't change your personality type, it can change the result you get on a type indicator (personality quiz, the official MBTI®, etc,.). One of the reasons this happens is that trauma can impact how you use, develop, and show your type preferences.
ISFJ: The ISFJ personality is known as “the protector,” “the defender,” or “the guardian” type. ISFJs are affirming, caring, and practical nurturers. This is the most common personality type among the general population.
Many studies … show that most adults become more agreeable, conscientious and emotionally resilient as they age. But these changes tend to unfold across years or decades, rather than days or weeks. Sudden, dramatic changes in personality are rare.”
In addition, being introverted is linked to spontaneously remembering more negative life events. Together, both personality traits — neuroticism and introversion — are linked to depression and anxiety. On the other hand, people with stable emotions who are more extraverted are at lower risk of depression and anxiety.
An individual with high neuroticism also experiences emotions such as fear, frustration, and sadness more often, generally viewing the world through a pessimistic lens. This leaves an individual more vulnerable to the development of mental health disorders, and is closely linked with depression.
Young and Midlife Adults
The average age of onset for major depressive disorder is between 35 and 40 years of age. Onset in early adulthood may be linked with more depressive episodes, a longer duration of illness, and therefore a more difficult clinical course.
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.
Research has indicated that individuals with high emotional reactivity (high neuroticism) and introverted tendencies (low extroversion) are more likely to experience anxiety than other personality types [101].
People who are extroverted, sensing, thinking, and perceiving are likely to catch your eye, experts say. These people are fun and adventurous, and that spirit will lure you in and keep you wanting more.
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.
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.
