I feel like in general INTPs do not have the decisiveness and confidence to enact strategies to elicit information in such a way. Each action and reaction changes the game and every potentiality would need to be evaluated and second-guessed before proceeding, so it would end up looking like an INTP staring in contemplation at a bored prisoner.
As far as *would* and INTP in general be amenable to this method? Speaking for myself, I don't think it is a reliable way of getting reliable information. Morally though I'm not opposed to the sacrifice of one opponent's rights in favor of the securing the rights of many allies. For me if you are not opposed to war in general it is hard for me to see how you can be opposed to torture, it is the same thing just on a personal scale.
I also agree with Dashing that personal exertion of control is not a motivator for me or other INTPs I would assume. We just want to be left alone, we don't much care about getting our way because we rarely have a definitive preference, we'll roll with things that we don't strongly object to.
