Bipolar Personality

Do bipolars share a common personality?

I took the Myers-Briggs Typology (Personality) Test nearly 20 years ago in a Psychology class. I learned I was an ENFJ, and was given a print out - personality profile. Not only was it Erie then to read a very accurate profile of myself, a profile more accurate than I could write myself, but it was even more Erie to learn that the test's predictions of what I would be like in Mid Life were true.

The personality test predicted that I would develop a passion for art, cooking, and nature. Twenty years ago, this prediction was laughable. I was the young, wild, party-girl. However, I am now finding a passion for these things.

I found the printout of the personality quiz that I had taken 20 years ago. I really wasn't sure what the quiz was called , or if it was something still used. I googled ENFJ which was printed on top of the quiz, and found loads of information about this personality profile. I am almost certain that it was the Myers-Briggs.

You can take the Myers- Briggs quiz- Free and no sign up- at http://www.humanmetrics.com/cgi-win/JTypes2.asp
It is 72 multiple choice questions.

I took the Myers- Briggs quiz again today and learned that I am no longer an ENFJ but now I am an INFJ. In other words, my personality is very similar to what it was 20 years ago. However, I is for Introvert and E is for Extrovert. Twenty years has turned me and Extrovert to an Introvert. (Oh, and I also had a good friend take the test, and she is also an INFJ. What are the odds? According to the information, 1 percent that I could be an INFJ.. So what are the odds that my good friend would also be?)

I am not sure if a study has every been done on personality and mental illness. It would be interesting to know if bipolars share a certain personality profile. Perhaps a way to predict mental illness?

I think computers have the potential to solve many mysteries of the human mind. Ah, if Jung only had the use of the computer. What we might just know now.
