What occurs when members of a larger group believe that giving is no more their responsibility than anyone else's?

Diffusion of responsibility

Explanation:Diffusion of responsibility is a pyschological effect that causes us to not act when there are many people around us with a belief that someone else except us will act.

For example, when we see someone being attacked in the middle of a large city , we may all stand and look but no one thinks of calling for help because everyone thinks someone else is doing it.

It leads to a bystander effect, when everyone stand and look and do nothing about a situation in front of them.

We feel less pressure to act when there are many people around us, one person thinks someone has called the police or this is not a serious matter if no one is doing anything about it.
