So kind of as a joke. I started having my characters roll insight checks (good old sense motive) whenever someone lied to them in story.
Of course, if plot demanded it they failed/succeeded, but i had one character who was like-
"Oh, was that a distress cry I heard? And is that a body I see? Oh they were killed by the perpetrators who ran away before i arrived leaving you conveniently alive and with only half the contraband we were trying to recover? Sounds legit."
