The risky-shift effect (see groupshift) is the increased likelihood for a group to support or partake in a risky decision or action. Larger groups permit a wider responsibility diffusion than the groups of two or three. As group size increases, the likelihood also increases that the group contains at least one highly risky and influential member who would be able to win over all the others. This demonstrates how larger group size and the increased riskiness of one person can cause the diffusion of responsibility from all group members to only the decisive, risk-taking member. From the group-processes standpoint, then, the risky-shift effect becomes stronger as the groups grow larger. And it has been proved by various studies that the risky-shift effect is more pronounced the larger the size of the group.
