Even in kindergarten differences in intelligence are so obvious that the children themselves, I suspect, often pick up on them. Some children can do simple Algebra in kindergarten whereas others, despite putting in lots of time and effort, are not even able to figure it out in high school. If we tell the not-so-smart kids that they will be able to catch up if they work hard enough, then what happens when this proves impossible?
