This is the basic Big 5/OCEAN personality test.
http://en.wikipedia.org/wiki/Big_Five_personality_traits
According to the MyPersonality facebook application my scores are as follows:
Openness 79%
Conscientiousness 48%
Extraversion 29%
Agreeableness 63%
Neuroticism 46%
(I just noticed that the way I copied and pasted this included a link to the descriptions of the traits that the application uses.)
My one confirmed INFJ real life friend has:
Openness 81%
Conscientiousness 75%
Extraversion 44%
Agreeableness 75%
Neuroticism 69%
It also aid that the states closest to her personality are West Virginia, followed by Main, followed by Texas. Mine are Maine, followed by Vermont, followed by New Mexico. My closest countries are Japan, followed by Chile, followed by Taiwan. Hers are Mauritinus, followed by Algeria, followed by Portugal.
She first registered as an INFJ based on MyPersonality's interpolation from her Big 5 score.

The Openness trait is this system's closest equivalent to MBTI's Intuition function. Conscientiousness is related to having a preference for an extroverted judging function. Agreeableness seems much more related to Extroverted Feeling than Introverted Feeling to me. I personally tend to think neuroticism may be related to introverted feeling, and also to having feeling as a tertiary function. It has only been scientifically demonstrated however to correlate to a more sensitive sympathetic nervous system. (Similarly introversion is correlated with a higher level of cortical arousal in the absence of external stimulation.)
According to the competing facebook application MyType, they are thus:
Extraversion: 12th percentile
Agreeableness: 72nd percentile
Conscientiousness: 21st percentile
Emotional Stability (the inverse of Neuroticism): 64th percentile
Openness to Experience: 74th percentile
My INFJ friend confirmed her INFJ type through MyType, but has not taken there Big 5 test yet.
We are both in Georgia, but don't really fit in here very well based on MyPersonality's statistics.
