A man is born innocent and society corrupts him. Starting at the earliest stages of human development, babies are the purest form of humanity. They have no impressions or opinions, they are a blank slate to be formatted. Although babies’ opinions are empty, they do have a general sense of right and wrong. As Tom Stafford says in his examples, “Babies are humans with the absolute minimum of cultural influence. They don’t have many friends, have never been to school and haven’t read any books.” Although babies lack basic language skills, they can still give off physical cues for their expressions and opinions. Babies can reach for things they like, or show surprise by looking at things longer. By using babies in a few experiments, psychologists can use how babies show expressions to find out whether a man is born good and is corrupted, or if he is born evil and is kept in check by society.
Humans are corrupted by society. Based on how they were raised, what they experienced as a young child or adolescent, or environmental factors, people turn out to be evil.
