Hmm.
Fi says, "I personally don't like it" as the final judgment.
Ti stands outside and at worst says the behavior isn't effective, or isn't rational, or is inconsistent.
I've already done that plenty of times. It seems everyone overlooks all of my points regarding the rationale of proper social interaction.
This also opens up the problem of quantification again. So one thing represents Ti, and another represents Fi, but what amount of these thing must be presented to qualify someone as a Feeler or a Thinker?
For instance, if a Thinker only used Ti as you describe, then no Thinker would ever have a concept of "flaming" or "trolling" as a violation. The more interesting thing is that they could conclude that something is unsound, but the conclusion would be of no relevence since they would be incapable of having an opinion that conclusion.
Now, since people obviously don't work this way, where is the line drawn? I certainly do what is attributed Ti, constantly. The case for me being a Feeler has never so much been the absence of Ti processes, but the highlighting of the presence of what are allegedly Fi processes in my behavior. So what do we make of this?
Do I use more Fi than Ti? I would argue that this assertion is simply not true. Is my over-all point guided by Fi or Ti? I do not know, because that's harder to locate. I would argue, however, that every human being is guided by Feeling. Thinking does not provide motivation, by definition. So this would really be an useful measure for distinguishing people. Then things are further complicated by context. For example, there are some topics in which nearly everyone comes across like a Feeler, because the focus of the topic itself does not demand much Thinking. So anyone that bothers to post in it is likely to express Feelings, like a farewell thread. So what does one make of all of these things when determining type?
And what of the dichotomies? Is it possible that I apply more Thinking
and Feeling than most people? I have to say that most attempts to prove that I am a Feeler have actually done more to make me doubt the validity of the entire MBTI.
