In particular, they talk about the "Big Five": openness, conscientiousness, extraversion, agreeableness and neuroticism. Evidence suggests that these traits aren't fixed at all, and some research shows you can intentionally change these personality traits.
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.
The Big Five personality traits are often used to measure change in personality. There is a mean-level change in the Big Five traits from age 10 to 65. The trends seen in adulthood are different from trends seen in childhood and adolescence.
While many may suspect that people's personalities are fixed in childhood, new research suggests that most people's personalities evolve throughout their lives.
It is possible to change a neurotic personality, results of 207 separate studies find. People become significantly less neurotic after undergoing therapy, new research finds.
Research shows that investment in activities with colleagues is associated with an increase in a person's conscientiousness, and de-investment in the social aspects of work can in turn contribute to lower conscientiousness over time.
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.
The Big Five remain relatively stable throughout most of one's lifetime. They are influenced significantly by genes and the environment, with an estimated heritability of 50%. They also predict certain important life outcomes such as education and health. Each trait represents a continuum.
Two seminal meta-analyses have shown that personality traits are relatively stable, but they also change, and they do so actually across the lifespan, meaning that there is no upper boundary. In fact, people aged 70 and older can still undergo pretty remarkable changes in their personality traits.
Our personalities were long thought to be fixed by the time we reach our 30s, but the latest research suggests they change throughout our lives – and bring some surprising benefits.
Studies show that maturation may have an impact on the five personality traits. As people age, they tend to become less extraverted, less neurotic, and less open to an experience. Agreeableness and conscientiousness, on the other hand, tend to increase as people grow older.
Extraversion and Openness were negatively associated with age whereas Agreeableness was positively associated with age. Average levels of Conscientiousness were highest for participants in middle age.
In terms of mean-level change, people show increased selfconfidence, warmth, self-control, and emotional stability with age. These changes predominate in young adulthood (age 20-40). Moreover, mean-level change in personality traits occurs in middle and old age, showing that personality traits can change at any age.
Extroversion, conscientiousness, agreeableness, and emotional stability are all traits that one may be able to deliberately increase, research suggests, though it's not yet known how permanent such changes are.
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.
Studies have demonstrated that Neuroticism and Extroversion decline with age, while Agreeableness and Conscientiousness increase.
However, as past research has shown, a permanent personality alteration takes at least 18 months of concentrated intervention. Recent studies have also shown that it's impossible to change your own personality—any change requires sustained outside encouragement by someone you are committed to.
Every third adult is expected to change in any personality trait over the next few years. Nine in ten adults will change in at least one Big Five trait over the next few years. Most changes happen between medium and high-low trait levels, not between extremes.
Scientists estimate that 20 to 60 percent of temperament is determined by genetics. Temperament, however, does not have a clear pattern of inheritance and there are not specific genes that confer specific temperamental traits.
And while personality traits are relatively stable over time, they can and often do gradually change across the life span.
Stability coefficients for the Big Five personality traits across 9 years were moderate to high, ranging from 0.73 to 0.97 in men and from 0.65 to 0.95 in women. The highest gender-equal stability was found for Openness to Experience and the lowest for Conscientiousness.
One of the biggest and most challenging aspects of Borderline Personality Disorder (BPD) is often 'The Chameleon Effect' – or 'mirroring'. This is the constant, unconscious change in the person's 'self', as they struggle to fit in with their environment, or the people around them.
We all have unique personalities. We are all different from each other. Each one of us represent a unique mix of different personality traits. No other person has the same mix of big five personality traits (and their facets) as you have.
The association between conscientiousness and intelligence is complex and uncertain. Some researchers theorize that people with lower levels of intelligence compensate for their lower level of cognitive ability by being more structured and effortful.
