Statistically may not be the right word when we don't have numbers here, but anecdotally it seems so correct to me that I'd settle for the word "empirically" here.
Kids that are annoying, are more visible than non-annoying kids. Therefore your mental recollection of such kids is biased towards kids that you find annoying.
Seeing how American kids are very attention seeking driven, I don't see how it's better than the alternative. Kids screaming top of their lungs to attract attention.
