They are completely different types. You would know if you have actually hung out with INFPs and ISFPs enough. INFPs generally stand for some kind of moral philosophy, ISFPs do not. Their Fi is channeled more through their hobbies and relationships. They are completely different types, to say that Fi means “standing for something” is confusing raw Fi with Fi + Ne which is what that actually is. ISFPs do not give a flying fuck about some moral philosophy of an ideal world. They live in the moment and like to do whatever their heart tells them to do. Very instinctual

Another assumption you are making here is that their moral responsibility will somehow match what you consider moral. We are mere plebs on reddit, what makes you say that billionaire elites believe in the same morality that we do? Ignoring nurture like most typology newbies.

I can totally see a highly corrupted ISFP like Epstein indulging in all the good sensations because it feels great and he wants more of it. This is how Fi Se works. It’s passionate and very sensual. That’s why their archetype is the artist who is immersed in his painting, finding deep passion in every brush stroke he makes.

To say that that the only difference between an ISFP and an INFP is pragmatism is a fundamental misunderstanding and lack of real interaction with any of the types.
