8. Demonstrative Function
The demonstrative function is used to support beliefs made in the vulnerable function, which made me think of why duals fighting can be very painful, but at the same time challenging.A person uses this element mainly as a kind of game, or to ridicule those who he thinks take it too seriously. They often intentionally go against its conventional usage simply to prove a point in favor of their creative function. However, this function is used quite often in private, to produce information of its element to support their creative function when focusing on making contact with the external world.A person will often have just as sophisticated an understanding of this function as his or her leading function. Unlike the ignoring function it plays a major part in a person's worldview, since as the vulnerable function of one's dual it requires especially delicate attention. Thus, when a person is given information regarding the element in the demonstrative function by someone else, they will tend to take it as obvious information that is irrelevant to completely focus on. One will often use the demonstrative function to defend and further support their beliefs made in the vulnerable function.The demonstrative function is easiest function to use (after the base function) yet often occurs sporadically. When one experiences a problem regarding this function, one must correct it as it does play a vital part in a person's worldview.- See more at: http://www.sociotype.com/socionics/f....UKxcdFDI.dpuf
For example, LSE is weak in Ni, so when EII does something to hurt this point, LSE can get very defensive and use Se as a defense. This, in turn, will frighten EII at its polr. They will then try to defend themselves through their Ni demonstrative function, which will not work either because LSE does not understand or care about it.
Due to having their vulnerable function attacked, the dual is forced to face it. At least, if they want the relationship to continue. They have to give into their "fears" of the Polr function and use their demonstrative function to fight back. When both realize the other's valid point, they have to let down their guard and admit their flaws. In other words, they have to be vulnerable.
Duals can challenge each other to be stronger, kind of like a boxer who gains most from the hardest match.
