Discuss the nature of groups and the bystander effect

What will be an ideal response?

A group consists of two or more individuals who interact and are interdependent. The bystander effect is the well-studied phenomenon (Darley and Latane and colleagues) that people are less likely to provide needed help when they are in groups than when they are alone. Reviews of studies on over 6,000 subjects in a variety of helping situations indicate that subjects who are alone help about 75% of the time, while subjects in the presence of others help about 53% of the time. The bystander effect is believed to occur because of diffusion of responsibility: when the responsibility is divided among many, everyone thinks that someone else will help.
