Good cop, bad cop

Interrogation and negotiation tactic

Good cop, bad cop, also informally called the Mutt and Jeff technique, is a psychological tactic used in interrogation and negotiation, in which a team of two people take opposing approaches to the subject. One interrogator adopts a hostile or accusatory demeanor, emphasizing threats of punishment, while the other adopts a more sympathetic demeanor, emphasizing reward, in order to convince the subject to cooperate. It is an instance of the Reid technique.
