Joyner Lucas, "Snitch"

In this clip, a man is questioned by detectives and asked to rat (snitch) on his partners. The rapper switches between the role of detective and lawyer, weighing up whether he should snitch on his partners or honor the street code. In a one-shot game, snitching is the dominant strategy (guarantees him a lighter sentence). However, snitching is not ideal. Cooperation is ideal. No communication between the players makes any cooperation harder. When communication is allowed, cooperation increases dramatically. Successful communication often consists of making promises (commitment to cooperate). Communication allows players to develop mutual beliefs about behaviour. In the end, he wisely chooses to speak to his lawyer.
