About 25% of the people who take the MBTI score close to the middle on one or more of the dimensions. Here's how to help them decide what their type is, including a description of Form J of the MBTI, and an unusual instrument called the PAS that describes not only the type you were born with, but changes you've made to your type in response to pressure from others.

"The basic principle behind the PAS is that people may actually have three types: the childhood type which is the most influential, the type after compensations made in adolescence, and the type after modifications made in maturity."
