Why not try and take the test demon?
Just out of curiosity.
By the way, what I'm talking about is not what I think introversion and extraversion are, this is what you will find anywhere on the net in any possible language about the psychological definition of extraversion and introversion according to Jung's theories, where Jung is important because it's him who invented the two words.

INxp ?
I'm not sure what you mean...
But, as I said, I'm probably more of an INTp, that's what I got form the "click here if.." decider, anyway.

Oh, then let's take the decider as a decider

Here is you're deeper review:

INTps often have a characteristic round-shouldered posture. Their necks are often not as well proportioned as other types and their heads seem to strain forwards. Their eyes have a sorrowful look about them as if they are about to be victimised in some way. Their noses are somewhat aquiline in shape which combined with often flattened cheekbones giving the false impression that their noses are large.

During conversation INTps may project their lower lips forward. INTps often show poor control of their lower jaw, allowing them to hang down. INTps normal facial expressions usually reflect wisdom and great life experience or sadness and victimisation. Although INTps are introverts, some of them may behave in a very extroverted manner.

INTps with more developed aesthetic taste are neat and tidy. They look after their clothes which they know well how to compose and combine. When they interact with others they are softly spoken and unobtrusive, leaving others the impression that they are intelligent and educated. When asking someone for something, they usually do it in such a way as to rarely be denied.

INTps with less developed aesthetic taste usually look like they are not bothered about their appearance. Their clothes are often old and worn and their footwear may be in a bad condition. When interacting with others they may be very active, pushy and sometimes even aggressive. They often do not obey the norms of politeness and may sometime be rough and vulgar, however this behaviour usually does not last a long time.

When INTps speak publicly they habitually adopt a slow, monotone speech pattern. This may have a sleep inducing hypnotic effect on their audience. INTps are good at noticing contradictions in theories or opinions and can focus others attention to this. They are able to predict short term forthcoming events in both visual and associative forms. Through observation and their own experiences INTps can create a precise model of others behaviour allowing INTps to predict peoples next moves. They often amaze and interest people with this quality.

INTps are very sceptical to others who are undertaking new beginnings. They are able to pour cold water on others burning enthusiasm. They try to keep others from being passionate as they consider strong emotions to be harmful. INTps also look after their health and can be very captious in these matters. For example, they may wash their hands more often than others do. They pay a lot attention to hygiene and sanitation.

INTps are often active in business and commercial matters. They have good abilities to quickly calculate profit. Usually they are relaxed and only undertake projects that show considerable return and profit. They are not afraid to run big businesses. Usually INTps are very economical. They do not like to make presents or lend money to others. Because of this quality they usually try to appear poorer than they actually are. However when it comes to spending money on themselves, they can be very generous.

INTps usually work slowly, paying a lot of attention to detail. In their activities they show a strict logic, that can sometimes become very pedantic and scrupulous. INTps may check that all home appliances are off many times before leaving.

STRENGTHS
INTPs are inclined to direct their attention inward, on abstract thoughts and ideas. Thus, they often prefer to work on their own, free from the distraction of other people. Using their Intuition to look beyond the obvious known facts in a given situation, they are flexible, free-thinking and adaptable. Open to new ideas, they will examine novel perspectives in a critical, objective manner. Logical and analytical, they are motivated to get to the heart of theoretical problems. Quietly curious and introspective, they focus on the deeper hidden patterns and meanings behind superficial forms and structures. Preferring to approach old problems from novel perspectives, they are not inclined to be rule bound, rigid or dogmatic. Focusing on fundamental principles, they tend to view life from an abstract, intellectual point of view. Sceptical, and inclined to ask challenging questions - both of themselves and others - they value intellectual competence and abstract logic.
INTERPERSONAL RELATIONSHIPS
With an Introverted orientation, INTPs direct their attention towards the inner world of abstract thought and ideas. Thus, they may sometimes need to be drawn out when in the company of others. Thoughtful and introspective, they may not be the first to put forward their own ideas, preferring instead to consider the deeper aspects of a problem before contributing to a debate or discussion. Given their preference for Thinking, they are likely to be more at ease when working with fundamental concepts and ideas, rather than managing interpersonal relationships. Inclined to keep their inner-most thoughts and feelings to themselves, others may take a while to warm to them. Although able to operate effectively in meetings and discussions, they may nevertheless be at their best when communicating in writing, where they may feel most able to express freely their creative, abstract ideas. Not inclined to be judgmental, they will be accepting of people who have a diverse range of ideas and opinions.
THINKING STYLE
INTPs are known for their creative, imaginative approach to problem solving which is grounded in a logical analysis of fundamental principles. More interested in understanding why things work, rather than simply perceiving how they work, they will look beyond the superficial facts in a given situation in search of deeper, hidden truths. Thus, they may feel more comfortable when seeking creative solutions to challenging problems, rather than being responsible for putting their ideas into action. However, their orientation towards the abstract and theoretical does not mean that they will lack interest in solving practical real-world problems. Rather, it means that they approach such problems by focusing on the fundamental concepts that underpin the problem at hand. Inclined to focus on the broader picture, attending to the detailed requirements of a task may not come naturally to them. While open to new ideas, they will not reject tried-and-tested methods if convinced of the value of such approaches.
HOW OTHERS MAY SEE YOU
Colleagues will value their logical, rational approach to problems. However, people who are, on the surface, more emotional than them may on occasion have difficulty relating to their tendency to evaluate situations in an abstract, theoretical manner. They are likely to be viewed as Œdeep thinkers¹ who may sometimes be prone to flights of fantasy. Moreover, more down-to-earth colleagues, who are less interested in the subtle nuances of a problem, may sometimes worry that they might lose sight of practical, day-to-day realities. Avoiding dogmatism, they will be seen as free-thinking, open-minded and adaptable. Inclined to become engrossed in their own thoughts, some may view them as being a little disorganised or absentminded at times. While some colleagues may see them as being a little shy, distant or even somewhat aloof, this is to misunderstand their private, inner-directed nature and their resultant tendency to focus on their own abstract thoughts and ideas.

Any questions?

It'd be easier with the test, but I would go for extravert

I always peg the "I" but the rest is inconclusive [as usual].

May I disagree? the result is very clear... I will post some more later on, it simply means to me that the other three characteristics are only slightly towards that direction.

ISTj ~ The Pragmatist

Yep.

INFp a.k.a. Intuitive-Ethical Intratim "The Romantic", you are confident and concrete regarding your own beliefs and fantasies, creative and inventive regarding how excited others are about you, delicate and insecure regarding your understanding of how things work, and you wish to have a clear perception and consistency regarding your physical strength or position of authority.

INTP, but I've noticed on these web tests that I can flip to E <something> instead of I sometimes.

One of the things I don't think is logical is trying to match up a physical description with a personality type. There's absolutely no way that can be accurate.

I also don't like that they only talk of the 'male' ISTj and not the 'female'. Are they trying to make the conclusion that an ISTj is more of a manly woman or something?

It's interesting how many of us are showing up as being introverts. It is, of course, absolutely possible to be extrovert, and yet here we all are... And can I say I'm not the least surprised!!

I am a hopeless introvert.

Last week I saw one of my classmates with his baby on campus so I stopped by to "coo" at the baby. Then I realised that I very well could have been intruding on his alone time with his child and apologized the next day after class. He wasn't bothered by it, though so I was worried over nothing. Social interaction tends to confuse me sometimes because what one person might consider rude another will shrug off. I tend to err on the side of caution most times and just keep to myself.

I have confidence in my academic abilities moreso than my social ones. Especially with classmates, as I don't know the protocol for socializing outside of class or school.

I don't like socializing, not really. I feel utterly drained of energy when I have to socialize and be nice and friendly and smile and chat...it's just not me. I can do it, but I would rather it be sporadically and I need plenty of me time afterward in order to feel myself again and get rid of the extra anxiety.
