Let's look at how the 16 scales correlate to the scale on the Myers-Briggs. A positive correlation means that as the score on one scale goes up, the score on the other scale goes up also. A negative correlation means the opposite.
For example, someone with a low score on Factor A is likely to show up on the Intuition side of the MBTI. Someone with a high score on Factor B probably would too.
For Intuition on the Myers-Briggs, here are the correlations from the 16PF:
The factors with the greatest positive correlation to Intuition are Q1, M, and I. Those with the greatest negative correlation are Q3, G, and L
