Which phenomenon suggests that people may feel less responsible for helping others in a group context?

The phenomenon that suggests people may feel less responsible for helping others in a group context is known as diffusion of responsibility. This concept arises when individuals in a group setting believe that others are also responsible for taking action, which can lead to a reduction in the individual’s sense of personal responsibility. As the number of bystanders increases, each person feels less compelled to act because they assume someone else will step in to help.

In situations where people are in a group and are faced with an emergency or need for assistance, the feeling of diffusion of responsibility can inhibit action. For instance, in a scenario where multiple witnesses observe someone in distress, each person might think, "Surely someone else will help," leading to inaction among the group. This contrasts with scenarios where a person is alone; their singular presence can heighten the sense of responsibility, thus prompting action.

Understanding this concept is important as it highlights the dynamics of social psychology and how group contexts can influence individual behaviors and decisions.
