Betwixt adolescence and adulthood, you get through a host of changes — jobs, regrettable haircuts and relationships that come and get. But what about who yous are at your cadre? As you grow older, does your personality alter?

Personality is the pattern of thoughts, feelings and behaviors unique to a person. People tend to recollect of personality as fixed. But according to psychologists, that's not how information technology works. "Personality is a developmental phenomenon. Information technology's not only a static thing that you lot're stuck with and can't get over," said Brent Roberts, a psychologist at the University of Illinois at Urbana-Champaign.

That's not to say that you're a different person each day y'all wake upwardly. In the short term, change tin can be well-nigh imperceptible, Roberts told Live Science. Longitudinal studies, in which researchers survey the personalities of participants regularly over many years, suggest that our personality is actually stable on shorter time scales.

In i report, published in 2000 in the periodical Psychological Message , researchers analyzed the results of 152 longitudinal studies on personality, which followed participants ranging in age from childhood to their early on 70s. Each of these studies measured trends in the Big Five personality traits. This cluster of traits, which include extroversion, agreeableness, conscientiousness, openness to feel, and neuroticism, are a mainstay of personality enquiry. The researchers establish that individuals' levels of each personality trait, relative to other participants, tended to stay consequent within each decade of life.

That pattern of consistency begins effectually age 3, and perhaps fifty-fifty earlier, said Brent Donnellan, professor and chair of psychology at Michigan State Academy. When psychologists study children, they don't mensurate personality traits in the same way they do for adults. Instead, they expect at temperament — the intensity of a person's reactions to the globe. Nosotros come up into the world with unique temperaments, and inquiry suggests that our temperaments as children — for example, whether we're piece of cake going or prone to temper tantrums, eager or more reluctant to arroyo strangers — correspond to developed personality traits. "A shy three-year-old acts a lot different from a shy 20-something. But there's an underlying core," Donnellan told Alive Scientific discipline.

Earlier temperament seems to affect later life experience. For example, one 1995 written report published in the journal Child Evolution followed children from the age of 3 until the age of eighteen. The researchers establish, for instance, that children who were shyer and more withdrawn tended to grow into unhappier teenagers.

But those decades add up. Throughout all those years, our personality is still changing, but slowly, Roberts said. "It'southward something that's subtle," he added. You don't find it on that five-to-x-year time scale, just in the long term, information technology becomes pronounced. In 1960, psychologists surveyed over 440,000 high school students — around 5% of all students in the country at that time. The students answered questions about everything from how they reacted to emotional situations to how efficiently they got work done. Fifty years later, researchers tracked down ane,952 of these sometime students and gave them the same survey. The results, published in 2018 in the Periodical of Personality and Social Psychology, establish that in their 60s, participants scored much higher than they had as teenagers on questions measuring calmness, self-confidence, leadership and social sensitivity.

Again and again, longitudinal studies have found similar results. Personality tends to get "amend" over time. Psychologists call it "the maturity principle." People go more than extraverted, emotionally stable, agreeable and conscientious every bit they grow older. Over the long haul, these changes are often pronounced.

Some individuals might change less than others, but in general, the maturity principle applies to everyone. That makes personality change even harder to recognize in ourselves — how your personality compares with that of your peers doesn't change as much equally our overall modify in personality, because everyone else is changing right along with you. "At that place's good evidence that the average self-control of a 30-twelvemonth-old is higher than a 20-year-quondam," Donnellan said. "At the aforementioned time, people who are relatively self-controlled at 18 besides tend to be relatively cocky-controlled at age 30."

So why exercise nosotros change and then much? Evidence suggests it's not dramatic life events, such as marriage, the nascency of a child or loss of a loved one. Some psychologists really suggest these events reinforce your personality as y'all bring your characteristics with you to that item situation, Donnellan said.

Instead, changing expectations placed on united states of america — as we adjust to university, the work force, starting a family — slowly wears us in, nigh like a pair of shoes, Roberts said. "Over fourth dimension you are asked in many contexts across life to do things a bit differently," he said. "In that location's not a user manual for how to human activity, just at that place'south very articulate implicit norms for how we should behave in these situations." And then we adapt.

Depending on how you look at it, information technology'south a revelation that'south either unsettling or hopeful. Over time, personality does change, progressively and consistently — similar tectonic plates shifting rather than an convulsion. "That opens upward the question: Over the life course, how much of a unlike person practise we get?" Roberts said.
