Fe is a decision-making process. Ne and Se are information gathering Ne-Fi together are looking for patterns in feelings. I swear--- what percentile of PerC knows ENFPs in real life? Looking for patterns in people is what a ENFP is highly tuned to do. I am highly aware of what people in my environment are feeling at all times. And I wonder if any introverts would disagree that extroverts know a sheer number of enough people to truly compare all this.Best Functions for this: Fe>Se>Si>Ni
Fe= Pretty self-explanatory. Good at understanding how people tick, easily picks up on other people's emotions.
Se and Si=good at picking up on subtle cues from the other person. Si is better at recognizing when details align with patterns they've seen before, but might get stuck if they don't have enough "data" to go off of.
Ni=similar to Si, good at recognizing patterns. In my experience, Ni predictions tend to be either stunningly insightful, or completely miss the mark.
Worst functions: Fi>Ne>Te>Ti
Fi= good at understanding people who are similar to them, bad at understanding people who are different from them
Ne= too in their heads to notice if someone has a crush on them
Te and Ti= do I really need to explain this one?
So, I would say ENFJ or ESFJ would be best at detecting if someone has a crush on them.
Eh, whatever... I wonder what the other ENFPs would say.
