Sam Harris argues that parents should never lie to their own children, even about something as seemingly innocuous as the existence of Santa, because all lies can sow the seeds of distrust between parent and child. I see his point. But if any kid asks me if Jackalopes are real, I'm going to continue to tell them they are, because that's the truth.
The High Cost of Tiny Lies
I don’t remember whether I ever believed in Santa, but I was never tempted to tell my daughter that he was real. Christmas must be marginally more exciting for children who are duped about Santa—but something similar could be said of many phenomena about which no one is tempted to lie. Why not insist that dragons, mermaids, fairies, and Superman actually exist? Why not present the work of Tolkien and Rowling as history?
The real truth—which everyone knows 364 days of the year—is that fiction can be both meaningful and fun. Children have fantasy lives so rich and combustible that rigging them with lies is like putting a propeller on a rocket. And is the last child in class who still believes in Santa really grateful to have his first lesson in epistemology meted out by his fellow six-year-olds? If you deceive your children about Santa, you may give them a more thrilling experience of Christmas. What you probably won’t give them, however, is the sense that you would not and could not lie to them about anything else.
