One thing to notice:

If we are interested in the differences between INTjs and INTps, a rather typical INTj result is oyburger's, whereas a rather typical INTp result is my profile. Compare our Enneagram profiles.

For the INTj we should expect a higher result on type 1 (Perfectionism) and a lower on type 9 (Calmness). The INTp should get a higher result on type 9 than on type 1. The reason for that is that there is a positive correlation between type 1 and the IJ temperament, and there is a positive correlation between type 9 and the IP temperament. And the correlation is probably pretty strong, too.
