Most of the time, but I also am very cynical about everybody. Its a good skill to have to question everyone's motives. Still i would trust my gut in any situation.
I feel that over the eons our sub-conscience has evolved to judge people accurately. That gut feeling is just an extension of that function. Gut feelings are important but sometimes you have to ignore them
My instincts don't sway to a certain direction when it comes to dilemmas or ultimatums. The only instinct I usually get is curiosity and once I've gone through my inspection I can see what choice suits me.
