There is a thing about the word "We" and the way people use it which is no less than fascinating. That world is to me the ultimate word of projection, that is to say the projection of our worldview onto others. The world "We" is according to socionics a world of the Super-Ego, it's a word of the Mental Ring. Of course, using it doesn't always point to information stemming from the Mental Ring, for instance on can use it formally as a subject according to rules of grammar, or using the royal "We" etc.. Nonetheless, more often than not when we use the word "we" in the absolute, we are referring to the "socion" i.e. society itself.
"We" as a group of humans in a given society or group are surely somewhat the same (of course that's a Mental Ring biased assumption). This idea is one of the most fundamental idea at the core of socionics. It's an Idea that I would qualify as of anthropological magnitude. This simple idea that we project our worldview onto everybody (we all strive for the same things, we all obey to a certain unwritten laws that we dare not transgress in public etc...) is a factor that if not taking into account can falsify the nature of truth and the reality of the human experience.
Here is an example ; in the scientific community the word 'we" is often used when they talk about the brain and the human condition.
However, if you listen to scientifics of different sociotypes they will describe the same phenomena occurring within our brain differently, they will even give you different reasons and interpretations but using the same "we" and therefore allude to a certain universality, something common to every human being. This bias in the scientific community is particularly visible in theoretical fields and soft sciences (like psychology !). Incidentally, these domains are constantly improved, some ideas get obsolete others come back to life and some are invented in the light of new discoveries.
Indeed, it is a basic truth of the human condition, that when we have reached the confine of our perception of the world without reaching a satisfying understanding of it, imagination takes over and tries to give coherence and satisfying understanding of things, and so the Gods were born, and so one day we were at the center of universe and another day we were in the middle of nowhere at the mercy of forces even the Gods couldn't fathom...
And so in another order of ideas, one can ask why is it that Psychoanalysis with all its flaws still practiced even today as if it was flawless ? One might believe that where there is a village, there is a Church. People believe in it (whatever "it" is), some believe in its curative power while others believe no less in its lucrative power...
