Where in To Kill A Mockingbird does it show people often fear what they don't understand?
In To Kill A Mockingbird, Boo Radley is the most prominent example of the maxim, “People fear what they do not understand.”
The neighborhood, of course, fears Boo Radley. Boo Radley was once a rambunctious teenager who made one too many wrong decisions. For his friends, these misdeeds resulted in a reform school; for Boo, they resulted in a decades-long imprisonment in his home. It is likely, therefore, due to this forced confinement, that Boo developed some type of mental disorder. For example, early in his confinement, he attempted to stab his mother with scissors.
