Extroverted sensing is considered the inferior function of the INFJ. Se has a strong awareness of the physical world around us. Since it’s fourth in our natural function stack, it’s not as strong as it is in an artistic ISFP or a live-in-the-moment ESFP. However, INFJs often enjoy the company of Se-dominant types because they help to bring out this side in us, which can easily be ignored with all the stuff going on in our heads.
When an INFJ embraces their Se side, they really appreciate sensory activities, like hiking, dancing, playing a musical instrument and even spontaneous adventures. It’s because of Se that INFJs tend to appreciate material things, such as clothes and home decor. However, since Se isn’t a top function, INFJs usually play it pretty safe in these categories, not wanting to risk sticking out in a crowd. This is one thing that differentiates INFJs from INFPs, who use Si, and are more likely to express themselves through fashion or, on the other hand, just dress however and not care what anyone thinks.
This function is usually more developed later in life, and can be a cause of self-esteem issues in INFJ children who function mostly off their top function, intuition.
