But in many cases, this arousal just as surely reflects emotions other than guilt stemming from malfeasance, such as understandable anxiety at the prospect of failing the test, indignation at being accused of a crime one didn't commit, and - perhaps in the case of my friend Ellen - guilt at the mere thought of having once fantasized about having committed a crime.
