Answer:
The use of expert quotes, and a personal example followed by a research study gives context to the idea of mob mentality and helps readers understand how it happens.
Step-by-step explanation:
This question refers to the 2014 text "When Good People Do Bad Things" by Ann Trafton. In this text, the author talks about a phenomenon known as "mob mentality." Mob mentality occurs when people lose sight of their individual morality and behave in the way that the group they belong to behaves, whether this matches their own morals or not. Because of this psychological pressure, good people can be led to do bad things. The text gives a personal example that the author experienced, as well as information about scientific research and expert quotes. All of this helps reader understand the phenomenon better.
