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 Thinking side of the MBTI. Someone with a high score on Factor B probably would too. For Thinking on the Myers-Briggs, here are the correlations from the 16PF: The factors with the greatest positive correlation to Thinking are N, E, and L. Those with the greatest negative correlation are O, A, and I.
