If this is true/false, then the answer is true.
In a prisoner's dilemma, the type of behavior that provides the most benefit for each individual is to cooperate.
If the prisoners cooperate, it means that the police won't have enough proof against these criminals given that they will give the same account of what actually happened. Instead of remaining silent, confessing, or betraying each other, the wisest decision for them is to cooperate and thus reduce their punishment.
I believe the answer is: Normative social influence.
Normative social influence refers to the process of agreeing/conforming the the view held by majority of group members in order to be a part of the group. This occurrence could affect different aspect of our life. For example, we can see that many people choose to adopt all belief from one political party without wanting to listen to the views of opposition party.
