Most children do not remain angry or embarrassed about the deception for very long. John Condry of Cornell University interviewed more than 500 children for a study of the issue and found that not a single child was angry at his or her parents for telling them Santa Claus was real. According to Dr. Condry, "The most common response to finding out the truth was that they felt older and more mature. They now knew something that the younger kids did not". In other studies, a small fraction of children felt betrayed by their parents, but disappointment was a more common response. Some children have reacted poorly, including rejecting the family's religious beliefs on the grounds that if the parents lied about the unprovable existence of Santa Claus, then they might lie about the unprovable existence of God as well.
