I think I'll spend a little time on this each day, not too much, adding more and more famous examples until there's an extensive gallery. I'm really open-minded when it comes to typology and most topics, but personally not convinced that any Perceiver (who tests as a clear P) has a dominant J function. I know a lot of IJs on the other hand with a dominant strong worldview and beliefs. This conclusion is from my experience with a lot of people irl, I'm very open-minded when it comes to typology, but I don't really buy MBTI's take on the functions. For you guys however, it's a project of sorts, that you can simply be open-minded to.
A P type has either dominant situational Perception (Pe) with a reactive worldview when needed (Ji, like in the below example Luke Skywalker, an Fi reactive type), or a P type has dominant holistic thought Perception (Pi) with a reactive situational resolve when needed (Je). Ji types on the other hand, like Daenerys Targaryen and Aragorn, are excellent examples of the Fi type with a firm Values worldview, related to their P cousin the NeFi, like Luke Skywalker with a worldview strong but more put on the back-burner. You have to watch some videos of these types, they're great examples of the types. In contrast, NiFe types like Kurt Cobain and Johnny Depp who have really weak and open worldviews, are constantly Perceiving dominantly to figure their internal world of ideas out: Fi isn't strong and confident like it is with the Fi types above, it becomes a slave to Ni whose purpose is to explore the mind and understand what Fi could be to them in different ways. This is very predominant of NiFes that an Fi value system is weak, wishy-washy, poorly-understood by the NiFe. INFJs jump right in with a keen understanding of what their Fi values are and what they are for others. INFJs often understand INFP's Fi more than they do:
In NiFes, Fe emotional morphing and tact with individuals is their most common reaction, that is because, even though they're serious, they have no real solid worldview, they're figuring out their mind and instead their Values are very situational and reactive to the moment, like in the FeNi examples Margaery Tyrell, Barack Obama and Jennifer Lawrence. Johnny Depp's acting is great example of Fe realization. NiFes can realize their J side fairly easily, once they realize they don't need to attach their Judgements to introverted beliefs, they can act and be externally decisive at a faster rate than INxJs. This attitude of reactive decisiveness is something difficult for the INxJ to grasp, because the INxJ is constantly hindered by belief systems, they are very self-disciplined. It's an illusion that INxPs have Ti/Fi, caused by MBTI brainwashing ime. Another great example is the Craftsman, SiTe, who utilizes reactive Te to get a feel for how things work in their environment but they don't use an inner belief system (Ti.) Other great Ni examples are Neo and Gandalf (NiTe) who eventually realized their Te, but who have primary Ni and Ti-slave. (Gandalf was trickier because he has 3 states very balanced due to age: introverted perception (Ni), extraverted resolve (Te), and introverted conviction (Fi). Introverted P seems to be his default life-personality, his true soul; he uses Te only when he needs to, he's learned to hone it, but overall is not that organized.) I have many more examples to come however I base this understanding on large samples of people I know irl.
If you're an INxP with a strong worldview and belief system, it's likely you are mistyped, as many TiNes type as INTx. In other words, Ns tend to type as more 'P' in general, because Intuition is a more taxing perception process that takes more time to visualize in daily life--the J scale needs to be adjusted.
People are calling IPs Ji and IJs Pi, but if you can bare with me with an open mind, I'm not sure they understand how incorrect that is in reality. We need to spend more time with IPs and IJs by understanding Introversion as internal orientation, not nonsocial (a mistype.) Extraverts can be quite reserved but are still primarily external. In this presentation, since you Polaris don't relate to having a solid inward worldview or belief system, if it is you type as J, that means your dominant way is Judging. Since there is no dominant worldview responsible for your primary Judgement lifestyle, your lifestyle is instead tied to a primary need for situational Resolve / Judgement in life (ENFJ) via a weak worldview. However, if you typed J by mistake on the test, then your type in this presentation is INFP (like ENFJ they have no strong worldview.) One thing we don't mistake in this system is INFJs as non-social and ENFJs as social, since that's not the function's definition: Xe is defined as object/situation orientation. Xi means that the object/situation goes primarily ignored, meaning, they have primary inward holistic orientation. For INFJ, this is where their dominant Judging lifestyle comes from from. These functions fit the types in MBTI around 10x better ime, once you get their E/I orientation correct; it's pretty clear. We just need to unwind the brainwashing, fix mistypes, and understand the slave function as kind of the 'toy' for the dominant. It's not real, but plastic and manipulated.
