'Children also hold different beliefs about the meaning of failure, and about the value of effort, depending on whether they think intelligence is fixed or malleable. For the child with the fixed view, failure is very negative. They may view a single test as a measure of their intelligence for the rest of their lives (Stone and Dweck, 1998). Children with the malleable view are less concerned about failure because they do not view performance on any one task as a reflection of how smart they are, and because they believe that if they do fail, there is something they can do about it: Try harder. Thus, children with a malleable view of intelligence believe that effort is useful. Children with a fixed view do not. For example, these children tend to agree with statements like, "It doesn't matter how hard you work—if you're smart, you'll do well, if you're not smart, you won't." These views lead children to an odd conclusion: Effort is a sign of stupidity. According to the fixed view, if you're smart, you don't need to work hard. Thus, working hard is a sign of not being smart. Dweck (2001) eloquently describes the trap these students have created for themselves: It is desperately important to them that they appear smart, but they believe that they must achieve the signs of success without working hard.'
