Scouts ability to deal with contradiction and hypocrisy as she grows up

This question is very similar to one you've alreay posted. When we meet Scout, she's only six years old. She's outgoing, emotional, and very intelligent. None-the-less, her reactions are often physical, and her words are unfiltered. As the novel progresses, Scout learns to control the physical and filter the emotional. She challenges things she doesn't believe in, but she challenges those things in ways that will not get her into trouble.
