Why Some MBTI Types Skip Auxiliary Function in Favor of Tertiary Functions

The Myers-Briggs Type Indicator (MBTI) framework is a well-known tool used for personality typing, offering insight into the cognitive functions that constitute each personality type. These functions are generally ordered as the dominant, auxiliary, tertiary, and inferior. However, some individuals may seem to skip over developing their auxiliary function in favor of their tertiary function for a variety of reasons. This article delves into these reasons and provides an understanding of why such development patterns occur.

1. Natural Preference and Strengths

Individuals often gravitate toward functions that align with their natural preferences. A person's tertiary function may be more appealing or easier to express than their auxiliary function, making it more likely for them to develop the tertiary function more readily. For example, someone with a dominant function of Introversion (I) and an auxiliary function that supports decision-making (Judging, J) may find the tertiary function of Intuition (N) more engaging or easier to utilize in everyday situations. This natural inclination towards the tertiary function can overshadow the auxiliary function, leading to underdevelopment of the latter.

2. Life Experiences

Personal experiences significantly impact the development of cognitive functions. Individuals may encounter situations that require reliance on their tertiary function, leading to its enhancement over the auxiliary function. For instance, someone working in a field requiring abstract thinking (such as creative writing or design) may frequently employ their tertiary function of Intuition (N) to its fullest, effectively marginalizing the auxiliary function. This continuous use of the tertiary function for tasks aligning with personal strengths can lead to its more pronounced development.

3. Stress and Coping Mechanisms

Under stress, people may revert to using their tertiary function as a coping mechanism. This behavioral pattern can lead to a stronger expression of the tertiary function in tough situations, at the expense of the auxiliary function. For example, someone with a dominant function of Extraversion (E) and an auxiliary function of Thinking (T) may feel overwhelmed by interpersonal conflicts and instead rely on their tertiary function of Sensing (S) to process information and manage emotions. This avoidance of auxiliary functions in stress-inducing situations can hinder their overall development and integration.

4. Misunderstanding of Auxiliary Functions

Some individuals may not fully understand or recognize the importance of their auxiliary function, leading to its neglect in favor of more accessible or familiar functions. In the MBTI framework, the auxiliary function plays a crucial role, but its significance might be overlooked by individuals who prioritize more evident functions. For example, a person with a dominant function of Feeling (F) and an auxiliary function of Sensing (S) might focus on their tertiary function of Thinking (T) because it seems more relevant to their daily life. This misunderstanding can prevent the full development of the auxiliary function, impacting overall personality integration.

5. Developmental Stages

Cognitive functions can develop at different stages in an individual's life. For many, the development of their tertiary function becomes more pronounced during certain life phases, particularly in midlife. During this period, individuals often seek greater balance and integration within their personality. As a result, the tertiary function may become more dominant, overshadowing the auxiliary function. For instance, an individual with a dominant function of Introversion (I) and an auxiliary function of Intuition (N) might find that their tertiary function of Feeling (F) becomes more prominent as they navigate middle-aged challenges, leading to a stronger emphasis on their tertiary function.

Conclusion

While the MBTI framework provides a structured approach to understanding personality, the actual development and expression of cognitive functions can vary widely among individuals. This variability can lead some people to skip or underutilize their auxiliary function in favor of their tertiary function. Understanding these dynamics can help individuals work towards a more balanced integration of all their cognitive functions, enhancing overall personal and professional development.
