Can You Change Your Personality?

The question of whether one can change their personality has intrigued researchers and individuals for centuries. While completely altering one’s personality traits may be challenging, strong evidence suggests that intentional efforts can bring about meaningful changes. Personality change interventions usually target specific aspects of personality, such as emotional stability, self-confidence and openness to experience. While not all attempts may lead to lasting results, consistent effort and perseverance can contribute to significant changes.

Definition of Personality

Personality is a unique set of characteristics, patterns and behaviors that influence an individual’s thoughts, emotions and actions. It encompasses  preferences, attitudes, beliefs and values, which contribute to a person’s distinct identity. Personality traits can be influenced by a combination of genetic predispositions, environmental factors and life experiences, but are commonly regarded as enduring and consistent in adult life. While certain traits are  relatively stable over time, research indicates that personality can exhibit some degree of change, especially on the occurrence of major life events. 

Overview of the Five-Factor Model (Big Five)

The Five-Factor Model, also known as the Big Five, is a widely accepted framework in psychology that defines personality through five core personality traits: extroversion, conscientiousness, agreeableness, openness and neuroticism. Openness reflects a person’s curiosity, imagination and willingness to engage with novel ideas and experiences. Conscientiousness encompasses traits such as organization, reliability and goal-directed behavior. Extraversion measures one’s level of sociability, assertiveness and preference for social interactions. Agreeableness relates to one’s interpersonal cooperativeness, empathy and inclination towards harmony in relationships. Finally, Neuroticism pertains to emotional stability versus reactivity. The Five-Factor Model provides a comprehensive framework for studying individual differences in human behavior and cognition, and forms the basis for numerous studies in the field of personality science.

Stability of Personality Over Time

Research consistently supports the stability of personality over time, with dimensions like extraversion, neuroticism and conscientiousness showing relative consistency throughout life. Longitudinal studies spanning decades have shown that, on average, individuals generally exhibit consistent patterns of behavior and attitudes throughout their lives. This stability is particularly evident in adulthood, where personality traits tend to remain relatively stable over extended periods. While life events and experiences can influence individuals and may lead to changes in personality, the core personality traits identified by the Five-Factor Model typically remain robust. This finding has significant implications for our understanding of human nature, as it suggests that personality traits provide a enduring foundation upon which individuals build their lives, shaping their interactions, relationships and life outcomes.

Nature Vs. Nurture in Shaping Personality

The age-old nature vs. nurture debate in psychology revolves around the extent to which genetic factors (nature) and environmental influences (nurture) contribute to the formation of one’s personality. While genetics undoubtedly play a significant role, as certain personality traits such as extraversion and neuroticism tend to run in families, environmental factors also wield considerable influence on personality development. Upbringing, experiences and cultural context all contribute to molding personality. In addition, the environment may act as a trigger or suppressor for the expression of certain genetic traits. Studies of identical twins who were raised apart and have very different personalities provide compelling evidence for the importance of environmental influences in shaping one’s personality.

Possibility of Personality Change

Since environmental factors have an impact on one’s personality, personality change is feasible through what the person has gone through. Various life experiences and interventions can lead to lasting shifts in personality traits. Engaging in therapy, self-reflection practices like journaling or meditation, and adopting a growth mindset can result in positive changes. Though not instantaneous, the potential for personality change offers hope to individuals striving for personal transformation and improved relationships. Understanding this empowers individuals to actively shape their personalities in alignment with their values and aspirations.

Malleability and Flexibility of Personality

It is essential to recognize that personality is not fixed but rather a dynamic aspect of an individual’s identity. Research has shown that personality can undergo changes over time, particularly in response to life events and experiences. However, intentional personality change can be a formidable task. Personality traits are deeply ingrained and may resist modification. The success of making such intentional change efforts can be affected by factors like motivation, resources and external circumstances.

Psychotherapy and cognitive-behavioral techniques are often used by mental health professionals to facilitate personality change. Numerous studies demonstrate the lasting impact of therapy on personality traits, particularly in reducing neuroticism. Such therapeutic approaches can help individuals explore the roots of their traits and develop strategies to manage and modify their behavior patterns.

Role of Major Life Events and Life Experiences

Major life events and life experiences hold significant power in shaping our personality. These encounters provide opportunities for learning, growth and adaptation, leading to changes in our demeanor and behavior. Grief, bad news, disappointment, traumatic situations and mental health conditions are examples of events that can profoundly impact our personalities. Grief, for instance, can evoke varied behavioral tendencies, such as withdrawal, anger or increased empathy. Similarly, receiving bad news or facing disappointment can prompt a reassessment of beliefs and priorities, thus affecting one’s personality. Traumatic experiences can also leave lasting imprints, making a person more anxious, have a lower self-perception or become more suspicious of others.

Challenges and Limitations of Intentional Personality Change

Modifying broad personality traits is difficult, as basic personality traits tend to be resistant to significant alteration. The impact of genetics and early experiences also influences personality development, making complete transformation challenging. Furthermore, as individuals age, they often revert to their natural personality preferences, hindering long-term change. Despite these obstacles, intentional efforts supported by a growth mindset can lead to successful changes, such as increased emotional stability or self-confidence, emphasizing the importance of consistent and dedicated efforts in achieving meaningful personality changes.


The question of whether one can change their personality is a complex and intriguing one. While personality traits are generally stable and deeply ingrained, research suggests that intentional efforts can indeed bring about successful changes. Though a better understanding the dynamics of personality, we hope you have gained valuable insights into the adaptability of your own traits and open new possibilities for personal growth and development.
