After seven experiments with hundreds of children, we had some of the clearest findings I’ve ever seen: Praising children’s intelligence harms their motivation and it harms their performance. How can that be? Don’t children love to be praised? Yes, children love praise. And they especially love to be praised for their intelligence and talent. It really does give them a boost, a special glow — but only for the moment. The minute they hit a snag, their confidence goes out the window and their motivation hits rock bottom. If success means they’re smart, then failure means they’re dumb. That’s the fixed mindset.

George Dantzig was a graduate student in math at Berkeley. One day, as usual, he rushed in late to his math class and quickly copied the two homework problems from the blackboard. When he later went to do them, he found them very difficult, and it took him several days of hard work to crack them open and solve them. They turned out not to be homework problems at all. They were two famous math problems that had never been solved.

Benjamin Barber, an eminent sociologist, once said, “I don’t divide the world into the weak and the strong, or the successes and the failures.… I divide the world into the learners and nonlearners.” What

People with a fixed mindset were only interested when the feedback reflected on their ability. Their brain waves showed them paying close attention when they were told whether their answers were right or wrong.

What did they know? They knew that human qualities, such as intellectual skills, could be cultivated through effort. And that’s what they were doing — getting smarter. Not only weren’t they discouraged by failure, they didn’t even think they were failing. They thought they were learning.

Yes, he was depressed, but he was coping the way people in the growth mindset tend to cope — with determination.

They know how to take tests and get A’s but they don’t know how to do this — yet. They forget the yet.

Like my sixth-grade teacher, Mrs. Wilson, these teachers preached and practiced the fixed mindset. In their classrooms, the students who started the year in the high-ability group ended the year there, and those who started the year in the low-ability group ended the year there. But some teachers preached and practiced a growth mindset. They focused on the idea that all children could develop their skills, and in their classrooms a weird thing happened. It didn’t matter whether students started the year in the high- or the low-ability group. Both groups ended the year way up high. It’s a powerful experience to see these findings.

I think intelligence is something you have to work for … it isn’t just given to you….

In summary, people who believe in fixed traits feel an urgency to succeed, and when they do, they may feel more than pride. They may feel a sense of superiority, since success means that their fixed traits are better than other people’s. However, lurking behind that self-esteem of the fixed mindset is a simple question: If you’re somebody when you’re successful, what are you when you’re unsuccessful?

As a New York Times article points out, failure has been transformed from an action (I failed) to an identity (I am a failure). This is especially true in the fixed mindset.
