I'm unsure of my type; I will show a couple pictures of myself, but I believe that typing by appearance is a very inaccurate way of typing someone. How it can be concluded that there is a relationship between one's appearance and one's type eludes me.
I'm basically unsure as to whether I'm an INTj, INFj, INFp, or ENTp. All of those descriptions fit me to some extent. Let me describe myself.
I received an honours degree with distinction in computer science. I planned on going to graduate school, but I hated the research course that I took so much, that I decided not to. I like reading about computer science theory, especially when it's laid out nicely in textbook format, but I have a hard time coming up with solutions to research problems that are not well-laid out. It's also possible that I just had a bad instructor, but I liked learning about computer science theory more than doing research. So, instead of going into industry and doing programming (which I find monotonous), I decided to go for a second degree. I'm in a very impractical field - philosophy. My thinking is that since I enjoy it so much, it's possible for me to get a graduate degree and teach at the university level. If not, then I have a math and computer science background to fall back on, and so I can teach high school.
Now, let's get to my personality. As is implied by the types I'm uncertain about, I get borderline results on the T/F scale. The way I see it, logic and emotion are not as opposed as some may believe. Sure, it's impossible to be logical and emotional at the same time, but I think that it's also impossible to be intuitive and logical at the same time. You could come up with intuitions and then analyze them for truth, but couldn't you have feelings and then analyze what they imply as well? Therefore, I think that the types are just generalities that represent specific trends in personality, trends that are not set in stone. Anyway, I can be very sensitive at times. If someone criticizes me or my ideas, I take it personally. It irks me and makes it difficult for me to reason critically. However, when I'm in a dispassionate state, I love coming up with all sorts of ideas and analyzing things just for the sake of it. The problem is that I can have such strong emotions that it takes a while for me to be able to get into this state. However, when I get there, I feel that I'm functioning at my best. I'm also irked by violence, not just any violence, but violence that's aimed towards the innocent. I'm not irked by violent aimed at someone who is "evil", as it is justice.
As I said, I like coming up with ideas. I'm not big on reading just for the sake of reading. When I read, I usually read with a specific purpose in mind. If I want to learn more about something, and it's usually something specific, I will devote a reasonable amount of time to understanding it. It's usually related to me or a theory I have. For example, if I question whether humour is a "right-brained" function, then I will do a Google search for -humor brain-, and skim through a few articles to see what they say, just so I can get a general picture of where in the brain humour resides. The only time I will devote a lot of time for reading is when there is a purpose behind it. For example, if I have to read a textbook to prepare for a test.
Now that I've described myself, here is my reasoning for agreeing/disagreeing with the characteristics of the types I've mentioned:
INTj: I like being logical. I'm very good at deductive logic, such as mathematics and formal logic (I got all As in the math courses I took in university), but I'm not so good at using logic in certain situations. For example, when I'm in a debate, I'm not very good at defending my viewpoint, because my ideas come about more intuitively than logically. It's only when I'm really certain about something that I can defend it well. Also, I'm not good at games of strategy, such as chess. I just have no feel for the game. However, if I were to ever be so motivated as to read a book about chess, then I would probably be much more capable.
ENTp: I fit the description at www.socionics.com really well, but I simply don't see myself as extraverted. Yes, I have a desire to share my ideas with others, but I don't like socializing just for the sake of socializing. I spend much of my time pondering my ideas by myself.
INFj, INFp: I'm lumping both of these together, because, as I said, I'm sensitive and have strong feelings, and I'm quite not sure which one is a better fit. The INFj description fits me quite well, but, if I were a feeler, I'd see myself as more of a dominant intuitive than a dominant feeler. What goes against these types is that I have a strong desire to reason logically.
(INTp: I test as INTp on www.socionics.com, but the description doesn't fit me at all, and, as I said, I'm close on the T/F axis.)
As for the MBTI forums that I habituate, I like the INTJ (INTp) forum, as I find they are analytical and straightforward, but I also dislike it, because a lot of them strike me as being harsh or emotionally negative. I also like the INTP (INTj) forum, because they are less critical and more detached, but I find that they go off-topic and don't usually have deep discussions like they do on the INTJ forum.
Finally, here are a couple pictures:
