“A jury’s vote’s supposed to be secret. Serving on a jury forces a man to make up his mind and declare himself about something. Men don’t like to do that. Sometimes it’s unpleasant.”

– Harper Lee

To Kill a Mockingbird, Chapter 23. Atticus cites a reason why people in Maycomb don’t want to serve on juries. He is suggesting here that they may have to confront their own racist ideas.
