Answer:
Personalization of the victim
Step-by-step explanation:
When we hear about a natural disaster that killed a lot of people, we tend to think of these people as a collective, and not as individuals. Therefore, we are able to think about it less than we would otherwise. On the other hand, when the victim is a single person, we tend to personalize him. We think of the person's history, and individual characteristics. This usually leads us to feel more sadness for the person than we would otherwise.
