A cross post

I've had questions and have read your questions about certain areas of the MBTI test, so after a little more research:

"This is the simple model. In fact, the Myers Briggs model is much more complicated than this - it is a dynamic model:
the preferences change and develop throughout life
the preferences interact with each other "

One area that I've questioned and see that others have as well is Judging. Mine was 11, which surprised me until I found this:

Judging and Perceiving
Judging and Perceiving preferences, within the context of personality types, refers to our attitude towards the external world, and how we live our lives on a day-to-day basis. People with the Judging preference want things to be neat, orderly and established. The Perceiving preference wants things to be flexible and spontaneous. Judgers want things settled, Perceivers want thing open-ended.

We are using Judging when we:

Make a list of things to do
Schedule things in advance
Form and express judgments
Bring closure to an issue so that we can move on

We are using Perceiving when we:

Postpone decisions to see what other options are available
Act spontaneously
Decide what to do as we do it, rather than forming a plan ahead of time
Do things at the last minute
We all use both Judging and Perceiving as we live our day-to-day life. Within the context of personality type, the important distinction is which way of life do we lean towards, and are more comfortable with.

The differences between Judging and Perceiving are probably the most marked differences of all the four preferences. People with strong Judging preferences might have a hard time accepting people with strong Perceiving preferences, and vice-versa. On the other hand, a "mixed" couple (one Perceiving and one Judging) can complement each other very well, if they have developed themselves enough to be able to accept each other's differences.

I do make lists, but I also postpone decisions. I schedule things, but then act spontaneously. I form and express opinions, but often decide what to do as I do it (especially with quilting). I love bringing closure so I can move on, but often put it off until the last minute. No wonder the J was only 11%.

and this one is very good.
