Personality is mostly seen as a stable set of traits that define how everyone thinks, feels, and behaves, and has long been considered relatively fixed by adulthood.
But the question of whether one can switch their personality after the age of 30 is both fascinating and increasingly relevant in our evolving understanding of human psychology.

The science behind personality change
EWN spoke to clinical psychologist Dr Khosi Jiyane to dive into personality and how it changes over time. She says, “Research in psychology suggests that while core personality traits tend to stabilise with age, they are not entirely immutable. Studies show that adults, including those over 30, can experience shifts in traits such as openness, conscientiousness, extraversion, agreeableness, and emotional stability. “
All these changes often occur gradually and can be influenced by life experiences, intentional behaviour changes, and personal growth efforts.
Factors such as new relationships, career transitions, therapy, or significant life events can catalyse personality development.

Practical ways to foster personality growth
- Self-reflection and mindfulness: Becoming more aware of one’s habitual reactions and thoughts can open pathways for change.
- Therapeutic interventions: Counselling or cognitive behavioural therapy can help modify maladaptive traits.
- Setting personal goals: Committing to new habits or social behaviours can gradually reshape personality aspects.
While personality becomes more stable as we age, it is not set in stone after 30. Through conscious effort and life experiences, meaningful change remains possible.
Embracing this potential empowers adults to continue growing and adapting throughout their lives, proving that personal transformation is never truly out of reach.
