What type do you think is the most judgmental of others? It seems like the most obvious answer that will come to many people's minds are Te doms. Maybe J types. Maybe Te types in general. Maybe Fe doms. They are more likely to come across forcefully. Is it true though? Are they really the most judgy types?
I'm going to posit that individuals with a judging function at the top of their function stack are the most judgmental. ENTJs and ESTJs clearly fall into that category. Their Te judgments tend to be somewhat objective in nature - fueled by Ni in the case of the ENTJ and Si in the case of ESTJ. The ESTJ will appear to be more traditionally judgmental but both are equal in my opinion in their judginess. Then there are Fi doms, ISFPs and INFPs, whose judgments are driven by their own personal and subjective values. Those types are deceiving. The ISFP seems so easy going and the INFP's window to the outside world is Ne, which hardly comes across as judging. Yet they can make a decision on whether or not they like someone within 20 seconds. There are the Ti doms, ISTP and INTP - I see them as less judgmental about people. I don't know. They are more wrapped up in their logic or frameworks to be as judging of people? Finally, there are the Fe doms. I don't really know many Fe doms so I can't say much there.
The judgments that tend to make me the most uncomfortable are those that aren't based in reality. Se and Si types are by nature more connected to reality, so I can get comfortable or at least understanding of their judgments. Even in those situations where I think they are wrong, I can understand them. What makes me more uncomfortable are those driven by intuition and those that are subjective because I don't understand the reasoning. I say this with full knowledge that I prefer Ni and Fi. To me, INFPs are the most judgmental though I believe this is not at all obvious to those that don't know them well.
I guess the whole idea of this thread sounds judgmental. But I'm only putting forth a theory. I haven't actually decided anything yet
