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.
Unfortunately my memory of this has faded. I know I had broken the charade by 6 or 7, but I can't recall my thoughts about it at the time. I recall playing along with it for rather Pascal's wager type reasons (more downside to risking the presents).
I take my poor memory of it as implying that it seemed less of a big deal to me. Same goes with the tooth fairy and Easter bunny. In comparison, unraveling the God story had a much longer and more significant timeline. Although the seeds of that were planted about the time of Santa's destruction I can't recall how the two are intertwined.
I would be surprised if the consensus here was that the story of Santa is a good parenting practice. We have a status quo bias potential here, so turn it around. If there was no such thing as Santa currently, would it be a good idea to invent him?
Or to further abstract it from reality, make up a whole bunch of stories. Would a child be better off with a pantheon of artificial creatures that want us to behave in certain ways? How about magical elves that make sure your schoolbus doesn't crash if you brush your teeth every night, or crows that poop in your milk carton if you tell a lie to a teacher. Seems all bad to me. There's enough challenge dealing with reality and our psychological bugs (like thinking that it's quite plausible that a crow pooped in your milk because you are an unlucky or bad person).
Some adults specifically told me not to say that I didn't believe in Santa, because if I didn't believe, I wouldn't get presents.
