Yet, a century later, what constitutes giftedness is still being debated. Some educators deny its existence entirely or say, with a roll of the eyes, that it is no more than a fantasy of pushy parents. Some take the view that all children have a particular gift of their own. Others conflate giftedness with talent when the two are often discrete: a gifted child may have been born with great potential but not have explored or displayed it. (Canadian psychologist Francoys Gagne is often cited for his theory that distinguishes giftedness from talent, offering explanations on how natural abilities can be developed into specific skills.)
