Once a liar always a liar? Have you ever noticed that there are some similarities between your and the personality of your parents? Is someone’s personality set in stone or we can evolve into someone different over time? There has been plenty of debate on the subject of whether experience or heredity shapes an individual's personality. Contrary to popular belief, personality is not something we are born with, according to scientists. Both nature and nurture have an impact on our personalities, characters, and behaviors, and sure, these things can change with time.
Is personality predetermined by genetics?
It is well established fact that a great portion of our personality is influenced by our genes. According to scientific estimates, your personality is inherited to a degree of between 30% and 60%. "Twin Studies: A Unique Epidemiological Tool," a study on twins, came up with some interesting findings. Even when raised in different situations, identical twins—who share 100% of their DNA—mostly display similar personality traits. This genetic link offers credibility to the theory that some characteristics of our identities are hardwired.
The "Big Five" personality traits—neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness—are frequently examined in these investigations. Some of these characteristics—like agreeableness and extraversion—have high heredity connections, while others—like openness to new things and experience—have less genetic ties.
Does the environment shape who we are
Although genetics play a part, our upbringing and surroundings have an enormous effect on how we become as individuals. The people we become are shaped by our relationships, early experiences, and cultural influences. To understand this better, take this example, children who grow up in friendly and positive surroundings are more likely to become more composed adults. Kids who experience abuse or neglect could grow up to be more impulsive because stress can "activate" particular genes associated with impulsivity.
According to the theory of neuroplasticity, our thoughts are not static. This theory describes the brain's capacity for adaptation and change. Over time, therapy, new skill acquisition, and life events can all result in personality changes. The personality of an individual can definitely be influenced and shaped by their experiences and surroundings.
Can our personality change over time?
The quick answer is - Yes! As we get older, our personalities can and presumably will change. Between the ages of 20 and 40, the majority of these changes take place. Many people report feeling more emotionally stable, in control of their emotions, and with greater self-confidence during this time. These modifications are the outcome of a natural process, very well known as maturing.

It's also important to remember that personality can be altered on purpose. People can consciously change the way they think and behave by using techniques like cognitive-behavioral therapy (CBT) and self-directed neuroplasticity. For instance, CBT can help someone who is introverted by nature become more extroverted by helping them form new social skills and gradually change their personality.
The debate of nature versus nurture
The complex correlation between environment and genetics shapes personality. Certain traits are inherited, yet they don't happen by themselves. The environment has the power to "switch on" or repress specific hereditary features, which eventually help in the development of an individual's personality. It means that although our personalities may be predetermined from birth, our experiences in life and the decisions we make can have a major effect on who we end up being.
