I've been thinking about the descriptions given to entp's and the apparent lack of Fi within them. I briefly read the description of Fi and it's correlation on deciding what we believe is important or not. First of all I would like to pose the statement that Fi is unavoidable. It is always used, and always works at it's fullest. I would say this without stating the fact that you could be mentally ill, and I do this because even having the cognitive changes that take place within a mentally ill patient they still have values (though sociopaths may differ, but that's a different subject) it's only what the values change into that has actually changed. That was off topic.
Anyway, I had another thought linked to the fact that T's don't need to show their emotions, or that the actions we make aren't based upon them, as well as the fact that we don't understand at times how you can make a decision solely on emotion. Because of this I began pondering on ways to develop, for what some people may feel, the F-ness that they feel they lack. I would say that this approach works better for E's than I's though just because the implementation does require spending most of your time around other people. It also hopes if you have the endless thirst for knowledge that NT's are I'm sure stereotypically thought of having, and most of the time I'd say that it is correct.
It's quite simple really. Use that big ole' T function too learn how the other person explains their own emotions. How they describe them, the movements they make. Analyze how to feel by observation. I think my ability to understand and express emotions has grown leaps and bounds just because I listened to others describe their own. I found that what they felt I feel too and so describing them similiarly works for me, and though this technique doesn't necessarily speak to the independent streak that NT's have, I think getting over miscommunications between thought processes is more important in the long run, but that's just me.
