In wider studies, the relentless pressure on a child branded a genius is now being seen as a prime reason for them falling back at school. In a frankly terrifying study of 10/11 year olds in New York, children were set tests. Afterwards, half of them were told, "You must be smart at this."

The children who had been told they had been smart picked the easy test. Those who were encouraged for hard work went for the harder option.
