...Sense Motive...protects you from being influenced into doing something via bluff....
Which doesn't come into play when an NPC is using Bluff to lie to a PC since PCs' attitudes/beliefs aren't affected by interaction skills.
Player: "Is the guard lying? I use Sense Motive."
DM: "Wonderful." *rolls die* "Do you think he's lying?"
