yeah, perhaps you're right on this. thinking back, i think most of the guys i know who wind up with these really compromising pictures (such as passed out in the back of a truck) were probably intuitive types. my impression was like, "wow, he's blasted in every photo!"
@ joy -- i admit i thought he looked a bit ISTp in some of the photos i saw him in, but i was mostly drawing that from the resemblance to the ISTp sketch on socionics.org. i just figure an ISTp would have better control in that arena (seems like i recall reading that ISFps always know how much they want to eat/drink etc. i would assume something similar goes for ISTps.)
