the speed with which they lied was unnerving. It came too naturally to them—such as the moment when a student told me that he had cloned a rabbit as a fifth grader, or when another said that a scientist in his country had discovered a way to change blood type A to blood type B, or when the whole class insisted that playing basketball caused a person to grow taller. I was not sure if, having been told such lies as children, they could not differentiate between truth and lies, or whether it was a survival method they had mastered.
