After taking lots of tests and getting help from a few informed friends, I've discovered that I don't actually know my type... but I've managed to narrow it down to INFP and ISFJ. Here's how I feel about each one:
I've always thought of myself as an INFP. The stereotype of an INFP seems to be someone who is sweet, soft-spoken, feminine, submissive, and idealistic. People also seem to think that they are the most sensitive of all the types. I'm a Highly Sensitive Person (HSP) and this could be where all the confusion is coming from. Still, I feel like my views are much like those of an INFP. I do a lot to help/support people who are mistreated by those in authority, such as prisoners, or kids getting yelled at by their parents. I'm extremely empathetic in this way, to the point where it annoys just about everyone. This is the problem I have relating to INFPs on a deeper level. According to several sites, INFPs keep their views hidden unless they are threatened, and they do not like to be the center of attention. I am not like this at all. I'm very outspoken about my views and the one thing I can't stand is being ignored (despite being painfully shy). Also, I love to think about and plan for the future. I have a lot of long-term goals and I think about them on a daily basis.
I wasn't particularly thrilled to find out that I might be an ISFJ, as two of my least favorite people are this type. I don't like the idea of being "traditional" or old-fashioned; I think it's important to recognize when something can be improved. For example, I have New Age beliefs and identify with the Green Party, while my entire family is conservative Christian. Despite this, I still have a lot in common with ISFJs. I feel obligated to protect anyone and everyone, whether I know them or not, simply because no one should have to be attacked, emotionally or physically, with no one on their side. This is just common sense to me. Extremely sensitive INFx guys tend to be attracted to me because of my nurturing and protective nature, even though I tend to prefer those who are stronger and more mature but still appreciate being cared for at times. It takes a lot to earn my respect, but it doesn't take a lot to be liked by me. I am extremely judgmental and may quickly brush someone off as being conceited or vain, but I feel like that's not the same as only liking someone after they display specific qualities.
All I'm sure of is that I most likely have Si. I don't know if it's particularly strong, but I probably use it more than Se. The rest sort of confuse me. If someone could explain them, that would be great. For now, I'm just sort of guessing. These are NOT supposed to be in order, by the way.
Se- From what I understand, this involves being aware of the physical world and operating in the moment as opposed to daydreaming or "spacing out". I've become much better at this recently. I don't prefer to use it, but I am very good at it when necessary.
Ne- Apparently this one is seeing hidden meanings in certain occurences. I thought I was good at this, but my intuition often leads me astray. It has led me into several abusive relationships. However, I'm still confused about what Ne really means.
Te- Categorizing/analyzing, from what I can tell. I think I'm slightly above average at this.
Fe- This function has me totally lost. I know it involves socially appropriate behavior such as being considerate, and I'm pretty good at that. But I've also heard that it's about dealing with the emotions of others. I'm not good at this at all. If someone else is upset, I always feel awkward and I wish I could help but I don't know what to do. On the flip side of this argument, I've cried while watching My Little Pony. It seems that I am very responsive to the emotions of others, but not quite sure how to deal with them.
Si- Using past experiences to make decisions. I used to be terrible at this, but now I'm very good at it. I see similarities in people I meet online and my abusive exes and a million red flags go up.
Ni- wtf is Ni? Someone help. If this is the one that involves seeing future possibilities, I'm pretty sure I'm awesome at it.
Ti- I was completely lost while reading the Ti description.
Fi- I've heard that Fi is about your own feelings/emotions. I don't know much else.
