Diffusion of responsibility

Explanation:

Diffusion of responsibility is a phenomenon where a person is less likely to take responsibility for action when they are in the presence of a large group of people. This happens because the individual assumes that others are either responsible for taking action or have already done so.

Since they are part of a big group of people, people will tend to assume that someone else will probably help or, if nobody is helping, that the situation is not that serious. Thus, they don't feel pressured to respond.

In this example, Roger was screaming for help as he was being beaten up. There were about 15 people standing nearby but none of them came forward to help. We can assume that, since they were part of a large group, each one of them assumed that the others were going to help Roger or maybe that the situation wasn't that serious. Thus, this lack of help illustrates diffusion of responsibility.
