Why what we think is irrelevant.

Everything we think is a result of our social organization; a system the individual makes up based on social presumptions that root back to the very origin of our subjective perspective. Assumptions, that if being viewed from an objective point of view, are quite pathetic. Breaking down to the confrontation of truth that everything we think simply makes no sense.

Now why is this so? I will try and explain that below.
Everything we think is formed by the perspective we think in. You could argue there are many different perspectives to think in, but for MBTI's sake, let's say there are 16. 16 different perspectives of thought. Every perspective with each own kind of discernment. Discernment based on a specific perception and developed through a way of prioritizing. This creates a complex of relevancy. What is rewarding, ought to be true. Isn't that what truth is? The accomplishment of prediction?. Anyhow, every perspective has it's own truth. It's own truth based on a perspective, which in that specific perspective is indeed rewarding and true. But when we would observe that truth from contrary perspective it wouldn't be considered truth but irrelevancy. This counts for everything. You can argue against everything, it all depends on the goal. If the goal is inner peace, making new friends is a wrong pursuit. If the goal is getting yourself acknowledged, making new friends is just wonderful. It all depends on the perspective.

Now why is it then, that there is no line of agreement? Well... That is because everything we think is a cause of sociability. Everything we think is based on our social organization. We can't think outside of that box. We can transform that box so that your thoughts are based on imaginative figuratives, but even then it is based on our social organization. The definition of being conscious is thus: To process social information.
Social information which is being processed by being contrasted with our worldview. A worldview that is made up by presumptions. As presumptions are based on the perspective we are in, we start being biased as soon as we exist. And because we all are biased, the only line of agreement is that what seems ordinary. A most votes count pursuit; which always break down to the question: "Is this rewarding?" If it is rewarding, it is still only rewarding in a specific, or multiple specific, perspectives. Perspectives that are based on presumptions. :)

Introversion considered from an objective POV.

- We introverts always want to mind our own business. So we think about conveying the point that we want to mind our own business. The people surrounding us must understand that we want to be left alone and thus we display avoiding behavior. And so we are constantly focused on this: "I want to make sure that I want to be left alone." We do this so that we can think, detached from that surrounding us. But that comes across to the others, specifically extroverts, as selfish. They are probably somewhat like: “Why are they thinking about not wanting to speak to me?! Am I not relevant enough? What a jerk! Whom is he to avoid ME!?”

- White lies need to be sustained. The introvert, to tell a story always tells white lies. He can't give the full truth as we reflect subjectivity. Subjectivity can't be explained through a matter of objective truth.
The white lies has a social purpose. A social intention. This intention must not be broken. If for instance the intention was to raise harmony, this intention will be that what we sustain. If we wouldn't sustain that intention, we simply have no reason to think. So to think, is basically to sustain an intention.
To portray his intention convincingly, requires the person, the introvert, not to be a hypocrite and live up to their intentions in order to portray them onto other people. These intentions however, are white-lies. And so things do not always turn out as we expected. The intention we had though, must be forced. So we would get ourselves in trouble, just to live up to our own logic. Ha. What a terrible faith has humanity xD

As an example: Why Pe usage automatically implies Pi.

Pe (Ne or Se) is the function to describe the conscious-mindset where you are completely focused on the perception of the now, the present moment. If all you sense is the present moment, the conclusiveness you will require to have thoughts must incline something to draw conclusions. If all that you perceive is the now, your conclusiveness must have something to string information from what you perceive together. You must discern with a certain knowledge taken into account, otherwise you couldn't discern. This knowledge POV is Pi.
