Answer:
The risky-shift effect.
Explanation:
The risky shift effect is a term that refers to the possibilities of making dangerous decisions when in a group.
When people are group and make decisions it may sometimes lead to groupthink. In this phenomenon, some individual in the group do not share their views points thinking that others have stronger opinions and that they should go with them.
In the given situation, roommates of Cade did not share their viewpoints. They knew that what Cade is suggesting is dangerous, yet they kept quiet (leading to the phenomenon of groupthink). This instance is an example of the risky-shift effect.
So, the correct answer is risky-shift effect.
