none. intelligence comes from determination to be intelligent. anyone can fail at this. however, i certainly thing istj's and esfp's are more liabe of going wrong at the idea of intelligence. but i think its more about instincts than type. i think these instincts have the kind of intelligence i value more: so sx(they as the wisest of all), sp so's(they see what is the most obvious thing, while im too in my head to notice the obvious stuff), sx so's(they seem to know the purpose of life) sx sp's(they see into people like no other) sp sx(they usually know things, despite the fact that they recklessly ignore negative consequences even when they know about it. i cant understand that mindset at all.) so sp's(good at manipulating people, and hiding their true motives.)
so yess.. i do think everyone has the potential for intelligence, but i think many forms of these intelligences are stupid, despite being a form of intelligence.
in my book, the most intelligent types in descending order: entp, intp, infj, enfp, enfj (the rest are liable to intellectual faults i cant see myself succumbing to.)
on enneagram: 1w9's, 5s, 4w5's, 6w5's and 9w1's are the ones i see most intelligent. but theres a one major flaw i see in 1w9's: ok, we strive to do everything perfeclty.. make everything the most efficient, do everything as best as it can possibly be done. GREAT. oh, except i forgot to question the necessity of the task im doing perfectly, thus wasting time being perfect in something i shouldnt even do. like there was this one 1w9 who was perfectionistic about baking. hed intensely pay attention that everything is perfect. OH, except the fact, that these things are to be eaten, NOT for the eyecandy. im always fascinated when i see a 1w9 randomly doing something damn trivial, but somehting which must be done, in the best way possible in this existence. like today i saw a female striding nose high in a shop, just getting to the point, just getting what she needs, not wasting time for anything else. much like i, except i hate my chores so much that i usually get lost in my head instead of doing them, while im "doing" them.
its certainly true that people often compensate one lack with something else. thats irrational. (i do it myself too. what i deprive in intelligence, i know im intelligent but i dont allow myself to use it due irrational emotions about the subject. mostly im so certain that unhealthy things such as car gases, fireplace smoke, wheath and alcohol has damaged my brains, since people in my country dont tell me about those unhealthy affects, and a child cannot really deviate from the society's effects like that.. so im intensely demotivated from using my intelligence, cause i want all or nothing. oh, the area i compensate in, is beauty and charm. it just pisses me so badly that people in my country are so ignorant about things that damage brains, the thing i consider dearest, and ive already had a whole childhood of exposure to these poisons that are common in my country. hell, i know people for are pro-finns, and they support the mindset of finnish recklessness so badly, that they try to force me into abandoning my health concerns!! >=( )
but there are also people who are genuine car enthusiast's, and those who are generally obsessed with imaginary statuses, and if an expensive car gives that, they get it.
