You are less likely to help someone if you are in a crowd.
The bystander effect demonstrates that the presence of others reduces your perceived personal responsibility to intervene.
A 1968 study found that individuals were much slower to report an emergency—such as smoke filling a room—when others were present compared to when they were alone. You look to others to define the situation; when they remain passive, you interpret the silence as confirmation that no action is required. You wait for someone else to act first.
In a group, your conscience is deferred to the inaction of strangers.
