Answer:
Diffusion of responsibility
Explanation:
Diffusion of responsibility is a sociopsychological phenomenon inwhich a person is less likely to take responsibility for action or inaction when others are present. It occurs when people who need to make a decision wait for someone else to act instead.The more people involved, the more likely it is that each person will do nothing, believing someone else from the group will probably respond. It makes people feel less pressure to act because they believe, correctly or incorrectly, that someone else will do so. And, when we don’t feel responsible for a situation, we feel less guilty when we do nothing to help.
