The biggest manipulators in my life have been F types. It takes a certain level of keying into the victim to successfully play someone. I'll give the grudge medal to INTJ though, such a long time can they remember transgressions and there is no redemption once you have stepped over that line. They will serve their revenge cold but it's rarely as artfully planned and executed as they'd like to lay claim to. More along the lines of I won't forget this and when the opportunity arises to let you taste the bitterness of life I will be there to offer you that cup.
ENTPs think they're machiavellian masterminds, but it honestly has to be either ENTJ or INTJ. Both are more patient than the ENTP, which can be a big part of manipulation.
ENTPs are so cartoonish.
I somewhat disagree. ENTPs are the real masterminds, except that they don't even try to be it, cause they are just too busy with fun and real life to make mastermind plans. Most INTJs, on the other hand, seem to have plenty of time for manipulation plans, which makes them prone to contemplating on world domination, but they never seem to execute their plans into reality.
ENTJs seem to have the right mix of intention to manipulate, executive abilities and sufficient time for execution of their plans. They would be the most successful at it then, regarding the NT population.
