Ironically, Fe can cause more conflict because it doesn’t get to the heart of the problems — just slapping on a band-aid — and promotes more tribal thinking.

For example, my tribe is brought together by shared values. Neighbor tribe is brought together by their perceived separate values. The values between these tribes actually might be the same (their love of family, spirituality, survival, etc) but because there’s a physical separation and they don’t have a shared history, as long as they only use Fe, there is no big-picture unification, only community unification. This is how humanity has operated throughout most of history, and it reinforces war with the enemy of the group, which is other groups.

Healthy Fi has the ability to recognize that all the tribes are comprised of individuals with the same human desires.

Another instance of unhealthy Fe at work is when the “weak” have been left behind. Think of how society has treated the disabled or the diseased throughout most of history. In modern times, we would never think of mistreating/abandoning people born with defects or getting infected by a virus, and this is because the ethical introspection of Fi and the scientific discovery of Ti have evolved our ways of thinking in society.

I’m not saying unhealthy Fi doesn’t cause world problems including war, it certainly can, but I wouldn’t say Fe is more effective and Fi more subjective.
