This article talks about sharing these categories with children in discussion, so that children can consider where they fit in. However, other work on 'mindsets' [1,2] suggests that labeling a child as 'gifted' or 'creative' in contrast to 'hard working' could negatively impact the child's future learning and achievement.

I wonder if Kingore, the author of this article, has written anything taking into account mindset research like Carol Dweck's.
