The bystander effect is a social psychological phenomenon where individuals are less likely to offer help to a victim when other people are present. This is due to the diffusion of responsibility, where individuals feel less personally responsible to take action when others are around. The presence of others can also lead to social influence, where individuals look to the behavior of others to determine how they should act. As a result, in situations where there are many bystanders, individuals may be less likely to intervene and offer assistance to someone in need. **
