A large group of people witness a man getting robbed in the park, but no one steps forward to help him or come to his aid. This is an example of:1. diffusion of responsibility2. mere exposure effect3. altruism4. groupthink
The diffusion of responsibility is the socio-psychological state where a person is less likely to take responsibility for the actions or the inactions in the presence of the others.
And is considered a form of an attribute and is responsible for the action taking and thus refers to the increased responsibility of action that each member of the group even when they know they are part of the group themselves.
