What is your Myers-Briggs personality type?

The Big Five model of personality traits has much better scientific validation than MBTI and related four-factor models. A short and very well-written book on the Big Five is Nettle's Personality: What Makes You the Way You Are.

It's interesting, but it's always hard to prove things in psychology. Ok, a person blinking a few times in an experiment might mean something, but who knows what. You have to speculate/interpret a hell of a lot. It's better than nothing, though.

Pointless comparision, because the MBTI is designing to uncover one's means of interacting with and perceiving the the world...not one's personality or who they are.  It was never supposed to be used to write up personality archetypes as Keirsey did with it.  The originators can't help it if their test has been misused and misunderstood for decades ;)...

The MBTI will not tell you that Joey likes to burn ants with a magnifying glass or that Jenny cries at every romantic comedy she sees...and in that sense, it is the other tests that are bogus.  The MBTI does not pretend to render that kind of precision on internal workings that can't be effectively quantified, only qualified with direct experience or hopelessly speculated on...it only tests for the person's interfacing (without trying to evaluate any subsequent interpretation of those perceptions that may take place) with the rest of the world, which is not completely internal or external, but the connection between the two.

Effectively, you're comparing a bastardized and bogus usage of the MBTI that turned the MTBI into some schlocky pseudo-scientific fluff with other schlocky psuedo-scientific fluff and saying it's worse.  It may well be that the big five is better than the astrologized MTBI variants ;)...but that's not a direct comparison with the actual MBTI.

Next you'll tell me that 7 Habits of Highly Effective People is scientifically based and rock solid ;)... 

...which is why tests that only measure and report how many blinks occurred are better than tests that try to categorize blinkers by speculated reasons for their blinking ;).

I am INFP, what is that?

INFP is Introversion Intuitive Feeling Perceiving...the opposite would be ESTJ, which is Extraversion Sensing Thinking Judging...the distinctions between each pair are below (from Wikipedia):

People who prefer extraversion draw energy from action: they tend to act, then reflect, then act further. If they are inactive, their motivation tends to decline. To rebuild their energy, extraverts need breaks from time spent in reflection. Conversely, those who prefer introversion "expend" energy through action: they prefer to reflect, then act, then reflect again. To rebuild their energy, introverts need quiet time alone, away from activity.

Sensing and intuition are the information-gathering (perceiving) functions. They describe how new information is understood and interpreted. Individuals who prefer sensing are more likely to trust information that is in the present, tangible, and concrete: that is, information that can be understood by the five senses. They tend to distrust hunches, which seem to come "out of nowhere".  They prefer to look for details and facts. For them, the meaning is in the data. On the other hand, those who prefer intuition tend to trust information that is more abstract or theoretical, that can be associated with other information (either remembered or discovered by seeking a wider context or pattern). They may be more interested in future possibilities. For them, the meaning is in the underlying theory and principles which are manifested in the data.

Thinking and feeling are the decision-making (judging) functions. The thinking and feeling functions are both used to make rational decisions, based on the data received from their information-gathering functions (sensing or intuition). Those who prefer thinking tend to decide things from a more detached standpoint, measuring the decision by what seems reasonable, logical, causal, consistent, and matching a given set of rules. Those who prefer feeling tend to come to decisions by associating or empathizing with the situation, looking at it 'from the inside' and weighing the situation to achieve, on balance, the greatest harmony, consensus and fit, considering the needs of the people involved. Thinkers usually have trouble interacting with people who are inconsistent or illogical, and tend to give very direct feedback to others. They are concerned with the truth and view it as more important.

Myers and Briggs held that types with a preference for judging show the world their preferred judging function (thinking or feeling). So TJ types tend to appear to the world as logical, and FJ types as empathetic. According to Myers, judging types like to "have matters settled".

Those types who prefer perception show the world their preferred perceiving function (sensing or intuition). So SP types tend to appear to the world as concrete and NP types as abstract. According to Myers, perceptive types prefer to "keep decisions open".

Note that even the Wikipedia entry, while carefully avoiding turning the MBTI and the Keirsey Temperment Sorter into one thing, makes the mistake of quoting some garbage, specifically about INFP, as it turns out ;)...:

The dynamics of the INFP rest on the fundamental correspondence of introverted feeling and extraverted intuition. The dominant tendency of the INFP is toward building a rich internal framework of values and toward championing human rights. They often devote themselves behind the scenes to causes such as civil rights or saving the environment. Since they tend to avoid the limelight, postpone decisions, and maintain a reserved posture, they are rarely found in executive-director type positions of the organizations that serve those causes. Normally, the INFP dislikes being "in charge" of things. When not under stress, the INFP radiates a pleasant and sympathetic demeanor; but under extreme stress, they can suddenly become rigid and directive, exerting their extraverted thinking erratically.

The above is a bunch of crap that cannot be derived from the test questions at all.  Certainly the way an INFP perceives things can make them lean in certain directions, but to extrapolate an entire psychological profile like some CSI-wannabe is ridiculous. 

What could be safely said about an INFP:

- INFPs tend to draw more energy from reflection than from action

- INFPs are top down thinkers, and concepts and principles tend to be more important to how you understand things than a big pile of facts and details

- INFPs tend to make decisions by immersing themselves in things rather than detaching yourself from them and looking from the outside

- INFPs like to keep their options open rather than make quick decisions

If you go back through the test, you will find that the questions directly contribute to the conclusions I listed, but you won't find any questions that directly contribute to saying that an INFP champions causes, avoids management, or becomes "rigid or directive" under high stress...

I didn't notice anything in the test about how bossy/subissive a person is. Seems that's the most important part of someones personality.

Just another reason the MBTI is not really a "personality test" ;)...

Pretty much.

Elusively transparent.  Tough to pin down, dependable as sun rise.  Manic depressive. Heh.

Seriously though this is one of ther reasons I have a problem with the whole temperament sorter tests.  There are a host of others which I don't care to get into but your basic type shouldn't change back and forth.

Having said that they do cover their bases saying one of the N, S, P, J will be primary and much stronger than the rest.  That does seem to be true.  I wouldn't say it is as bad as astrology.  Maybe Tarot cards.

Am I the only one that got 100% at something?

100% wow, thats a real outlier.

I know that for the first version of the test I took in the mid-to-late 90s, which had 14 questions for each of the 4 pairs, I scored 27/28 for "N" and "T".  Also, "I" wins out for me usually by 1-2 questions over "E", and the "P" and "J" scores flip back and forth over the years (and yes, this is possible even for an accurate testing methodology...people do change ;)...).

Lol, well, you are quite the statistical anomaly ;)... so you were split 9/9, 11/7, 9/9, and 9/9 (assuming you did the 72 question test)...

Wow, that is very interesting!

According to the Keirsey Temperament sorter, you are a "Healer"

"Healers present a calm and serene face to the world, and can seem shy, even distant around others. But inside they're anything but serene, having a capacity for personal caring rarely found in the other types. Healers care deeply about the inner life of a few special persons, or about a favorite cause in the world at large. And their great passion is to heal the conflicts that trouble individuals, or that divide groups, and thus to bring wholeness, or health, to themselves, their loved ones, and their community.

Healers have a profound sense of idealism that comes from a strong personal sense of right and wrong. They conceive of the world as an ethical, honorable place, full of wondrous possibilities and potential goods. In fact, to understand Healers, we must understand that their deep commitment to the positive and the good is almost boundless and selfless, inspiring them to make extraordinary sacrifices for someone or something they believe in. Set off from the rest of humanity by their privacy and scarcity, Healers can often feel even more isolated in the purity of their idealism."

Confused?

Ok... so basically, if you have a personality type, (which everyone does), you are a great person, according to the descriptions. By deduction, we now know that everyone is great! All the bad in the world must just be my imagination ;)
