Certainly other people have noticed the prototypical INTJ's general lack of trust in people, life situations etc. why is it that this type in particular tends to lack trust in external things? Could it really be as simple as that their dominant introverted intuition perceives many possible outcomes to a given scenario, causing them to anticipate potential bad outcomes? Or do you think instead that something could have happened to them early in life that caused them to become hypervigilant and thus rely on this (seemingly hypervigilant it's self) introverted intuition function, which causes them to read into situations and constantly wonder about or fear potential bad outcomes? Your input is much appreciated, but explain your reasoning please. Thanks in advance all.
