According to Dr. McKay from the University of New England in Australia, "the persistence of fandom in stories like Harry Potter, Star Wars and Doctor Who well into adulthood demonstrates this desire to briefly re-enter childhood."
The scientists argue that should children discover that Santa isn't real, they are liable to lose faith in the ability of others to tell them the truth and are left in a moral dilemma. That’s why the report in the Lancet Psychiatry says that "children’s trust in their parents may be undermined by Santa."
Meanwhile, psychologists claim that sometimes lying to children may be the right thing to do. For example, when a beloved pet dies, it is better to say that a cat or a dog goes to a "special place" (animal heaven) and not to talk about their death.
Regardless of what some over-educated, white-coat wearing kill-joys say, if Santa doesn't exist, who is going to deliver all the presents to the children worldwide on Christmas Eve?
