Detect Lies
Defaults: Perception-6, Body Language-4, or Psychology-4.
This is the ability to tell when someone is lying to you. It is not the same as Interrogation; Detect Lies works in a casual or social situation. When you ask to use this skill, the GM rolls a Quick Contest of your Detect Lies skill vs. your subject's IQ (or Fast-Talk or Acting skill). If you win, the GM tells you whether the subject is lying. If you lose, the GM may lie to you about whether you were lied to...or just say, "You can’t tell."
Modifiers: +1 for Sensitive or +3 for Empathy, or -3 for Low Empathy; +4 if your subject is Easy to Read. If the subject is of a different species, the GM may assess a penalty – see Physiology Modifiers.
