Child psychologist Bruno Bettelheim explored the topic of fairy tales and socialization in his book, The Uses of Enchantment: The Meaning and Importance of Fairy Tales. He claimed that fairy tales help children master the problems of growing up by addressing issues involving love, fear, death, isolation, abandonment, evil vs virtue, and good vs bad. Bettelheim also discussed the indirect socialization lessons that young children can identify with, like the hero, who serves as a good role model and the villain, who exhibits socially unacceptable behavior. In addition, he stressed that fairy tales are structured in the same simplified way that children think. For example, the characters in fairy tales are usually one-dimensional; the witch is mean and ugly, the princess is beautiful and kind, and the prince is strong and brave.
