Which Letter is most important to you? I, S, T or P and why?

[ThoughtProcess]

^Bwahaha!!!

They're all important and I wouldn't be me without any of them.

[OctoberSkye]

I'm gonna guess I for ZC.

I love being a sensor.

[Psilocin]

Man, I really can't say I care.

But, srsly, A.

[ThoughtProcess]

Well, if I had to pick one it'd likely be T because it processes all of the sensory perception input. Also, I abhor stupidity.

[Galldune]

Another dumb topic sigh....

[Stand Alone]

E, if you're playing jeopardy or something.

[Galldune]

I'm just going to drop this a move on...maybe depends on how I feel and If anything else dumb comes from this topic..

Dominant: Introverted thinking (Ti)

Ti seeks precision, such as the exact word to express an idea. It notices the minute distinctions that define the essence of things, then analyzes and classifies them. Ti examines all sides of an issue, looking to solve problems while minimizing effort and risk. It uses models to root out logical inconsistency.[13] ISTPs live in a world of logic, on which they base their decisions. They process information from their auxiliary function to create strategies for action at a moment's notice. They love to examine complicated systems.

[alionsroar]

I guess in order:
T: Without it, I wouldn't be able to do anything alone, I'd just be a sentient being like a plant.
S: Without it, I'd just be trapped in my own mind. You might then find me in a mental ward or wandering in the desert talking to the sky.
I: I'd prefer if my extraverted and introverted functions were a little more balanced, it would help me deal with stuff a bit better. On the other hand it's nice that I don't have to be constantly involved in the real world to feel good. On the third hand maybe it would be better if I could like being around people more:)
P: What is this good for? So I am able to change my mind and live more freely? So I have Se/Ti instead of Si/Te. Very well then.

I agree with this naked statue.
