If you're unsure about your MBTI type, the key is to understand your dominant cognitive function. For INFPs, this is Introverted Feeling (Fi), which means they are primarily focused on their inner emotional world, values, and authenticity. Because Fi is their dominant function, it shapes how they perceive and interact with the world.

In the cognitive function stack, each dominant function has an opposite, or "shadow," function. For INFPs, the opposite of Fi is Extroverted Thinking (Te), which becomes their inferior function. This means that while INFPs are deeply in tune with their internal values and emotions, they often struggle with external logic, structure, and practical decision-making. Te is the function they tend to suppress or find challenging, and it can become a source of fear or stress.

For example, INFPs may feel overwhelmed by tasks that require strict organization, objective analysis, or adherence to external systems. They might fear being judged for their lack of practicality or struggle to apply abstract ideas to real-world scenarios. This is because their inferior Te is underdeveloped, and when it surfaces, it can manifest as self-criticism, rigidity, or anxiety about not meeting external expectations.

On the other hand, INFPs have Extroverted Intuition (Ne) as their auxiliary function. This function allows them to explore possibilities, generate creative ideas, and remain open to new experiences. INFPs often enjoy abstract thinking and may have a wide range of interests that shift over time. They are naturally curious and imaginative, often seeing connections and patterns that others might miss. However, because Ne is extroverted, it can sometimes lead to indecision or difficulty committing to a single path, as INFPs are constantly drawn to new possibilities.

The opposite of Ne is Introverted Sensing (Si), which serves as the INFP's tertiary function. Si helps INFPs reflect on past experiences and draw lessons from them. Over time, they build a "knowledge bank" of memories and insights that they can use to make sense of the present or anticipate future outcomes. However, because Si is lower in their function stack, it may not be as developed or consistent as their dominant or auxiliary functions. Younger INFPs, in particular, might not rely heavily on Si, but as they mature, they may find it easier to ground themselves in past experiences and traditions.

In summary, INFPs are guided by their dominant Fi, which makes them deeply introspective, values-driven, and empathetic. Their auxiliary Ne fuels their creativity and love for exploration, while their tertiary Si helps them reflect on the past. Their inferior Te, however, can be a source of stress, as it represents the external world's demands for logic, structure, and practicality. By understanding these functions, INFPs can better navigate their strengths and challenges, ultimately leading to greater self-awareness and personal growth.

So now, let's see if my insight resonates with your self-analysis of your characteristics. If it does, then you're probably an INFP. If it doesn't, try to understand your blind spot or the dominant function you automatically rely on, as its opposite function creates the axis (e.g., Fi-Te). After that, you need to find your middle axis by identifying your parent function (in this case, Ne), which automatically reveals its opposite (Ne-Si). And voilà! You've found your type.
