When you mean SP do you mean
XSXP?
Well for the mypersonalty one i got ISFP and for the other i got ISTP.
marm's right, going to jung is probably the best thing to do. and it'll take a bit of work, probably.
i also really like the descriptions of functions here -- http://www.cognitiveprocesses.com/index.html
i tried to make them into a quiz for you.
I got ISFJ. I almost chose #4 for the first question. Had I selected that, I would have gotten INTP.
What's clear is that I'm a Si/Ne and Ti/Fe user.
I don't think I have quite the great attention to detail as suggested by the Si paragraph nor do I pay quite as much attention to hidden meanings as suggested by the Ne paragraph.
The closest thing to an official MBTI test (the real one you have to have paid for)
The official MBTI test, which you have to pay for is probably one of the more reliable tests out there but even that mistypes about 25% of the time.
Another concern of mine is that we know that the Form G currently under-reports SPs. Stephanie Rogers, who is doing her dissertation on SPs, has hypothesized that many of the sensing questions on the current Form G are biased toward introverted sensing. As a result, her research indicates that extraverted sensors tend to select the intuiting responses rather than the sensing responses, therefore, creating the under-reporting of SPs.To my knowledge, the committee that developed the Form M did not take into consideration the function-attitude perspective. As a result, I am very concerned that the bias toward particular function-attitudes still exists.
