Luke walks around his busy college campus between classes. He notices smoke coming from the side of the cafeteria, but assumes that someone inside already has called the fire department. What phenomenon does this example illustrate

This question lacks options, options are:

A. The just-world hypothesis

B. Diffusion of responsibility

C. Deindividuation

D. Groupthink

The correct answer is B.

Explanation:

Diffusion of responsibility  occurs when people have to make a decision, but wait for other people to do it first, that is, it is the phenomenon by which a person feels less responsible for intervening in an emergency to help the victim when there are other people present than when he/she is the only witness. The reasoning that inhibits helping behavior is that surely someone else will help. Diffusion of responsibility  focuses on the fact that when there are multiple observers, the responsibility is divided among all and as a result no one helps.
