Consider motivations, before effectiveness, maybe.
Perhaps the NT liars are effective, because it frequently isn't an outright untruth, but more of a selective truth, which works to create an impression the NT is not bothered to correct.
What is a lie - a counter to/of reality?
If that is the case, an ideal is a lie, isn't it, since no reality can meet an ideal.
By clinging to truth, ideals, principles, we create a deep need for illusion, paradoxically.
So the NT could be the most effective at it simply because they're incapable of seeing the lies as wrong - "rational blinders". In their search for perfect systems - what can be, the gaps created due to what is, are too easy to fill with lies. And a lie to the self, if believed, makes a more convincing liar to externals, simply.
At their worst,
INTPs lie to themselves that they are better than others, can game any system: it is this that creates the illusion of competence they seek, but raises expectations they later suffer from, when reality intrudes.
ENTPs need masks to live. We suffer when some possibilities are closed, and are apt to select what truths to tell (the flex referred to earlier), in order to keep options open.
INTJs play cold games of subterfuge in an attempt to control from the inside and test boundaries to select their path. Failure to consider opinions of others deemed "not worth it/not up to the mark" could lead to being blindsided, simply because an opinion could hold truth, independent of the speaker. If you've ever tried to get a point of realism through to an INTJ in full swing, you'll know what this means.
ENTJs wear the masks of ENTPs to seek the same rule INTJs do. But there is only one truth - theirs. Is this not a lie? To whom?
So.. perhaps the NT is most effective, because they've the greatest need for illusion, to close the gap between the unreachable ideal and the reality.
