The victim of a road accident sometimes does not get help because even though many people are standing around the scene of the accident, each one thinks the other will help. This phenomenon is called ___________.

Diffusion of responsibility

Pro-social behaviour may also be reduced when the number of bystanders is more than one. For example, the victim of a road accident sometimes does not get help because there are many
people standing around the scene of the accident. Each person thinks that it is not her/his responsibility alone to give help, and that someone else may take the responsibility. This phenomenon is called diffusion of responsibility. On the other hand, if there is only one
bystander, this person is more likely to take the responsibility and actually help the victim.
