Yes, Carl Jung’s & MBTI cognitive functions can change over time, though the extent and nature of these changes can vary depending on several factors.
Developmental Phases
According to Jungian psychology, each individual has a dominant function that develops early in life, followed by an auxiliary function that supports the dominant one. Over time, especially in the second half of life, the tertiary and inferior functions (initially less developed) can emerge and become more integrated into the personality.
This process is often linked to individuation, a concept Jung described as becoming more self-aware and balanced by integrating the unconscious aspects of the psyche into consciousness.
Life Experiences
Major life experiences, such as trauma, career changes, or significant personal growth, can shift how one’s cognitive functions are used. For example, a person might develop inferior function if circumstances push them to use it regularly.
Stressful situations can also cause someone to rely more on their inferior function, which may feel less natural but can lead to growth over time.
Intentional Personal Development
Some people actively work on developing their less dominant functions through personal development practices, therapy, or self-reflection. This can lead to a more balanced use of all four functions.
Aging and Maturity
As people age, they may naturally shift towards using different cognitive functions more frequently. This is partly because as individuals mature, they often seek balance and wholeness, developing previously underutilized functions.
In later stages, individuals might engage more with their introverted functions, even if they were primarily extroverted earlier in life, or vice versa.
Environmental Influences
The environment, including social, cultural, and occupational contexts, can influence which functions are more developed or emphasized. For instance, a job requiring a lot of detail-oriented work might strengthen the use of introverted sensing (Si), even if that wasn’t a person’s initial dominant function.
Unconscious Processes
Jung believed that the unconscious plays a significant role in developing cognitive functions. Dreams, slips of the tongue, and creative processes might reveal underdeveloped functions and bring them into conscious awareness, gradually leading to change.
While the dominant function typically remains consistent throughout life, the auxiliary, tertiary, and inferior functions can develop and integrate over time due to personal growth, life experiences, and intentional effort. This change process aligns with Jung’s idea of striving toward psychological balance and individuation.
