On the 4/29/07 episode of The Simpsons there was a sign at Springfield Little League Park reading:
"Warning: Your child is not as good as you think he is."
For most parents, (although certainly not my wife and I because we underestimate our son’s greatness) this sign would help correct bias. So, should signs like this be posted occasionally?
Warning: Your reality may not be as true as you think it is
Ha!
