it's just a modern day index for the basic 16 or so personality types... unfortunately humans just have to categorise, it's nothing more nothing less, religious beliefs in or out, it doesn't matter... what, you touchy feely types think there's an infinite number of personalities?.. just remind yourself right this moment of ALL those people you have lost interest in, throughout your lifetime. "lost interest in," it doesn't come down to 'Life' or 'situation'..then think about ALL the people that have simply stopped checking up with you... people weave in and out of peoples' lives because the only commonality we all have is that we all get fed up with each other sooner rather than later. if anybody believed in the real 'value' of love and friendship, this world would not be so fucked up....anyways, i don't even remember what the point is...oh yes, the index just supports a simpler framework for identifying personality (people) types..... and their subsequent psychological predispositions should they experience severe duress. i can see it OP if you're still here. thx.
