INTJ vs INTP
While both INTPs and INTJs are concerned with the rationality of a given argument, INTJs tend to be less speculative and more careful with their arguments than INTPs. INTPs, who are typically more right-brained
than INTJs, are more holistic
in their approach to truth. Therefore, an argument that is rationally sound and “rings true” to the INTP may be deemed sufficient. INTJs, in contrast, tend to be more cautious
in their appraisals. Whereas the INTP may be satisfied with catching the drift an argument, INTJs attend more closely to the way it is stated and whether or not it is empirically-grounded
. INTJs are more concerned with the individual components of the argument, including their arrangement in a linear and logical sequence
so that a reasonable conclusion can be drawn. In the strictest sense, INTJs are more logical, analytical, and factual than INTPs
Since INTJs are often masters of logic and language, with vigilant attention to the manner in which things are articulated, they can represent a source of frustration for all types, even INTPs. INTPs enjoy making intuitive leaps
from one subject to the next and are adept at formulating connections among even the most disparate topics. As a result, a given INTP might come to believe he has arrived at an important new theory of the universe following an hour’s work with a pen and a sketch pad. INTJs, through often possessing strong powers of intuition, funnel things more carefully through the left side of the brain
. Consequently, they often display little patience or interest in an INTP’s random musings, demanding the INTP employ more specifics and linearity in his or her argument
. This can be quite difficult and frustrating for INTPs, who may consider INTJ overly nitpicky and fussy
. While some INTJs may exercise their questioning as a means of frustrating or embarrassing their interlocutors
, in the majority of instances, they are merely requesting information that their logical apparatus demands for conducting a viable evaluation of any argument.
Though INTPs may see themselves as “system thinkers,” this is much more accurately applied to the thinking of INTJs. For INTPs, the outlines of information tends to get blurred in their minds, intermixing in a way that emphasizes the unity of the whole over the identity of the parts. INTJs are also able to see the whole, but are also adept at preserving the identity and distinct relationships between the parts. Granted, the INTJ’s “big picture” may not be as all-encompassing or grandiose as that of the INTP, but this is often because their careful minds do not grant them the freedom to move at the same speed and to cover as much ground as is true of their perceiving counterparts.
