From Scientific American Mind

June/July 2008

When children are very young, they all express creativity, but by the
end of the first grade, very few do so. This is because of
socialization. They learn in school to stay on task and to stop
daydreaming and asking silly questions. As a result, the expression
of new ideas is largely shut down. We end up leaving creative
expression to the misfits - the people who can't be socialized. It's
a tragedy.
