How many types of people does scout think there are in the world?

Scout Finch believes there is only one type of people in the world - good people and bad people. She learns this from her father, Atticus Finch, who tells her that it is important to see people's goodness and not simply judge them based on their actions or appearances. Scout's belief in the inherent goodness of people is a recurring theme in "To Kill a Mockingbird."
