Abstract
This paper integrates theoretical and methodological evaluations of the effect of group size on helping. Bystander theory includes a reward-cost model for understanding the general helping context and a more specific designation of three psychological processes that produce the bystander effect. The three processes include: diffusion of responsibility, audience inhibition, and social influence. The present analysis identifies incompatibilities between the general model and the three processes and incompatibilities between the three processes and the definition of the bystander effect. Implications of these problems in the theory extend to the passive confederate design, one of the two major methods used in bystander research. This method is an attempt to test the bystander effect by manipulating social influence. But, because of a previously unrecognized disjunction between social influence and the bystander effect, we conclude that passive confederate studies do not actually test the bystander effect.
