It is an example of Pluralistic ignorance
Step-by-step explanation:
When something terrible happens to a person, it is essential to step ahead and help. However n reality most people tend to ignore such circumstances terming then as unconvincing, or they separate themselves from being involved. A person is suffering and needs attention.
