I might have to take back what I said.
The greatest strength of INTJ is their secrecy and their above average intelligence.
But their biggest weakness is their J is too obvious , or their Te is too strong.
You can't manipulate people with a strong Te, and INTJs suck at hiding their Te.
If you want to manipulate people, you have to make them believe they have freedom of choice or action, rahter than being a chess piece.
But if the J (or Te) is too strong, then it becomes too obvious.
when you start ordering people around and go into they XNTJ mode, the manipulation will become obvious.
Ps are better than Js at manipulating, because they can shrug off if things don't go according to plan. but Js (esp strong Js) get anal retentive when things aren't going as planned.
All you have to do is tell an INTJ "I don't feel like it" and it will throw them off the tanget.
Maybe INTJs can only manipulate another strong J, like ENTJ.
P manipulation is more subtle, you don't know what they are up to. When you are manipulated by a J, you will eventually get the feeling they are forcing their agenda on you.
I(introversion) are better manipulators than Es.
But P (perciever) are better manipulators than Js, because P manipulation is way more subtle. They let you believe you are free, while secretly pulling the strings.
I'll quote Gothe
" None are more hopelessly enslaved than those who falsely believe they are free. "
and INTJs suck at doing this.
I mean I have to compliment your type for being great at mind chess games and all, but your inability to let things go with the flow will be your downfall.
I admit, you might be way more intelligent than us ( i don't make the classical mistake like other entps thinking we are the smartest and the greatest), but your Te is your achilles heel.
(a piece of advise for you, if you want to play manipulation games with us Ps , you better hide your Te well)
I guess we'll have to see in real life what you are capable of, and I will always find out what i want to know.
