ENTP - "Inventor". Enthusiastic interest in everything and always sensitive to possibilities. Non-conformist and innovative. 5% of the total population.
Interesting. I usually come out as INTP, but in this case I came out as 53% extroverted, 46% introverted, just the other side of the line.
Extroverted (E) 53.33% Introverted (I) 46.67%
Intuitive (N) 61.54% Sensing (S) 38.46%
Thinking (T) 65.79% Feeling (F) 34.21%
Perceiving (P) 67.74% Judging (J) 32.26%
For the record, Myers Briggs is one of the few personality tests that I've noticed is that effective.
