You know how, when you're a kid, you get explanations for some things, but for others you just have to use your own logic.  Sometimes you can come up with explanations that are completly logical and completely wrong.  Other times you just erroneous assumptions based on incomplete data.  I was surfing through the blog by the author of a new book called "Parentonomics", about parenting from an economists point of view. 

He linked to a great episode of This American Life called Kid Logic.  It's well worth a listen with many amusing and touching stories about things kids think.

He also pointed to another amusing site:  I Used to Believe.  It's a giant collection of user submitted stories about different things they used to believe growing up.

For my part, I used to believe that you were supposed to wear underwear with the tag out.  I wore whitey-tightys and the tag was always on the outside when they came back from the wash.  I just assumed that was the way you were supposed to wear them - it makes sense in an odd sort of way - if the clothes you wear on the outside have a tag on the inside, then the cloths you wear on the inside must have them on the outside.  I think I wore them that way until High School when I was changing in the locker room and someone pointed it out.

I also used to wonder why soldiers who were about to be bombed didn't just shoot the bombs out of the sky.  Obviously, all you needed to do was shoot the bomb and you'd be fine, right?

Then there was the time I asked for some toy and my parents said we didn't have enough money.  I asked them why they didn't just go to the bank and get some?  That's where the money comes from, right?

Do you have any examples of  "kid logic"?
