I've long entertained a dubious regard for the practice of lying to children about the existence of Santa Claus. Parents might claim that it serves to make children's lives more magical and exciting, but as a general rule, children are adequately equipped to create fantasies of their own without their parents' intervention. The two reasons I suspect rest at the bottom line are adherence to tradition, and finding it cute to see one's children believing ridiculous things.
Personally, I considered this to be a rather indecent way to treat one's own children, and have sometimes wondered whether a large proportion of conspiracy theorists owe their origins to the realization that practically all the adults in the country really are conspiring to deceive children for no tangible benefit. However, since I began frequenting this site, I've been exposed to the alternate viewpoint that this realization may be good for developing rationalists, because it provides children with the experience of discovering that they hold beliefs which are wrong and absurd, and that they must reject them.
So, how did the Santa deception affect you personally? How do you think your life might have been different without it? If your parents didn't do it to you, what are your impressions on the experience of not being lied to when most other children are?
Also, I promise to upvote anyone who links to an easy to register for community of conspiracy theorists where they would not be averse to being asked the same question.
Most people are able to learn social rules without having things declared explicitly. Yes, it sucks for those of us who learn best when they understand what is going on abstractly. We would get a massive advantages if we could get everything declared explicitly. Yet there are others who actually learn these things better when the game isn't made open. They can maintain the whole internal plausible deniability thing.
Is the act of the parents - that of going along with cultural norms of faux-deceit - still evil if it actually makes their children better able to succeed socially? Where does the 'evil' lie? In what the parents do, the DNA of humanity or maybe even in the abstract nature of competition?
Yes. Other-optimising and deliberately changing someone's map so that it doesn't reflect the territory are hard to make a case for. "Cultural norms" is not such a case. I am not convinced there are people who actually learn how to play better when they don't know the rules of the game.
