Hey, I'd like to see people post their cognitive functions in a hierarchical manner, as you've probably seen around here on people's signatures and whatnot. To test for your functions, take this survey:
Understanding the Eight Jungian Cognitive Processes / Eight Functions Attitudes
It will ultimately give you the percentage strengths of the various functions. If you notice that the results also guesses your MBTI type, but possibly get it a bit wrong, it's because they're comparing your results to the classical theories for each type's functions. For example, I'm an INTP, yet the theory goes that INTP's sequence follow this pattern:
Ti > Ne > Si > Fe
However, mine goes something like this:
Ti ? Ne > Ni > Fi > Te > Se > Fe > Si
If I then compare my results using the chart at the bottom of this page: The 16 Type Patterns
to other types and their theories of function sequences, I notice that while I'm most like INTP, some things don't match. I'm also somewhat similar to ENTP, and maybe even INTJ, INFJ, or ISTP.
I was inspired by a thread about someone not fitting into their type exactly. This method seems to shed some light into some aspects that do not allow you to fit well into a type's box, while also showing you how you're similar to others.
