So many people I've run into know their Meyers-Briggs Type Indicator (MBTI) that I'm wondering how many people here know theirs and are willing to share? The MBTI is the mother of all personality type tests. The true test is quite long and basically is a list of multiple choice questions that can tell you or others, particularly counselors and employers, how you think and what type of personality you have. Many people gain some insight into how they operate in the world after taking the test and it's very helpful finding careers that match your personality type and thinking pattern. On the MBTI, I'm an INTP. Each letter indicates a particular mode of thought. In my case, my temperament is Introverted, iNtuitive, Thinking, Perceiving, in Carl Jung's archetypal structure, The Thinker. One blurb about my type says: Logical, original, creative thinkers. Can become very excited about theories and ideas. Exceptionally capable and driven to turn theories into clear understandings. Highly value knowledge, competence and logic. Quiet and reserved, hard to get to know well. Individualistic, having no interest in leading or following others. Now on that same scale I've changed a bit over the years, as a teen and younger man I was an INTJ: Independent, original, analytical, and determined. Have an exceptional ability to turn theories into solid plans of action. Highly value knowledge, competence, and structure. Driven to derive meaning from their visions. Long-range thinkers. Have very high standards for their performance, and the performance of others. Natural leaders, but will follow if they trust existing leaders. Then grew into an INTP though I have tested as INFP (the two tertiary indicators are usually very close) depending on my life stages so your personality type isn't set in concrete, but it's unusual for the first two indicators to ever change radically. Here's INFP: Quiet, reflective, and idealistic. Interested in serving humanity. Well-developed value system, which they strive to live in accordance with. Extremely loyal. Adaptable and laid-back unless a strongly-held value is threatened. Usually talented writers. Mentally quick, and able to see possibilities. Interested in understanding and helping people. To be honest, I see parts of myself in all three descriptions but even then they are closely related in temperament. It's fascinating to see yourself as others see you and this is something the MBTI can help with. There are even organizations devoted to people of certain MBTI sorts where you can talk to people who think as you do. It can be very helpful in learning how to overcome communications problems with other people, choosing careers, and finding culture that stimulates you. If you don't know your type you can take a quick and dirty test here to give you an idea of your pattern though the true test is only taken in person. There are many other sites out there with similar tests and there are no wrong answers. No one type is any smarter nor more sophisticated than any other. The MBTI simply takes Jung's sixteen archetypal personalities and sorts you into one of them.
