Dweck believes that children’s mindsets are profoundly affected by how we praise them. What should be praised is not just success and signs of intelligence, but the application of the learning process – the effort, perseverance, strategizing, and resulting improvements. This fosters motivation and a sense for how success can be achieved. If we praise only successful results and other signs of intelligence, we may give the child a temporary confidence boost, but we may unwittingly be fostering a fixed mindset. The result is greater fragility, and a dependence on constant validation.

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.

Dweck’s work with children revealed two mindsets in action — a “growth” mindset that generally thinks big and seeks growth and a “fixed” mindset that places artificial limits and avoids failure. Growth-minded students, as she calls them, employ better learning strategies, experience less helplessness, exhibit more positive effort, and achieve more in the classroom than their fixed-minded peers. They are less likely to place limits on their lives and more likely to reach for their potential. Dweck points out that mindsets can and do change. Like any other habit, you set your mind to it until the right mindset becomes routine.

The experience led Dweck to develop the idea of two contrasting mindsets that shape our attitudes to our own and others’ abilities. People with a ‘growth mindset’, as she called it, like the positive pupils above, see their intellectual ability as something that can be developed through effort, learning and practice, while people with a ‘fixed mindset’ believe they were born with a certain amount of brains and talent and nothing they can do will change that. Growth mindset people are the more go-getting bunch. Faced with problems, they engage and persevere. Failure isn’t permanent, it’s success not just yet. Using electroencephalograms (EEGs) scientists found more brain activity relating to error adjustments among college students with a growth mindset than among their peers with a fixed mindset.7 Growth-minded people also showed better accuracy after mistakes.

The fixed mindset limits achievement. It fills people’s minds with interfering thoughts, it makes effort disagreeable, and it leads to inferior learning strategies. What’s more, it makes other people into judges instead of allies. Whether we’re talking about Darwin or college students, important achievements require a clear focus, all-out effort, and a bottomless trunk full of strategies. Plus allies in learning. This is what the growth mindset gives people, and that’s why it helps their abilities grow and bear fruit.

...in the fixed mindset, you don’t take control of your abilities and your motivation. You look for your talent to carry you through, and when it doesn’t, well then, what else could you have done? You are not a work in progress, you’re a finished product. And finished products have to protect themselves, lament, and blame. Everything but take charge.

Parents think they can hand children permanent confidence — like a gift — by praising their brains and talent. It doesn’t work, and in fact has the opposite effect. It makes children doubt themselves as soon as anything is hard or anything goes wrong. If parents want to give their children a gift, the best thing they can do is to teach their children to love challenges, be intrigued by mistakes, enjoy effort, and keep on learning. That way, their children don’t have to be slaves of praise. They will have a lifelong way to build and repair their own confidence.

In my research, I have identified two mindsets that people can have about their talents and abilities. Those with a fixed mindset believe that their talents and abilities are simply fixed. They have a certain amount and that’s that.

When people with the fixed mindset opt for success over growth, what are they really trying to prove? That they’re special. Even superior.

As Morgan McCall, in his book High Flyers, points out, “Unfortunately, people often like the things that work against their growth.… People like to use their strengths … to achieve quick, dramatic results, even if … they aren’t developing the new skills they will need later on. People like to believe they are as good as everyone says … and not take their weaknesses as seriously as they might. People don’t like to hear bad news or get criticism.… There is tremendous risk … in leaving what one does well to attempt to master something new.” And the fixed mindset makes it seem all that much riskier.

Believing that your qualities are carved in stone — the fixed mindset — creates an urgency to prove yourself over and over. If you have only a certain amount of intelligence, a certain personality, and a certain moral character — well, then you’d better prove that you have a healthy dose of them. It simply wouldn’t do to look or feel deficient in these most basic characteristics. Some of us are trained in this mindset from an early age. Even as a child, I was focused on being smart, but the fixed mindset was really stamped in by Mrs. Wilson, my sixth-grade teacher. Unlike Alfred Binet, she believed that people’s IQ scores told the whole story of who they were. We were seated around the room in IQ order, and only the highest-IQ students could be trusted to carry the flag, clap the erasers, or take a note to the principal. Aside from the daily stomachaches she provoked with her judgmental stance, she was creating a mindset in which everyone in the class had one consuming goal — look smart, don’t look dumb. Who cared about or enjoyed learning when our whole being was at stake every time she gave us a test or called on us in class?

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?

Believing that your qualities are carved in stone — the fixed mindset — creates an urgency to prove yourself over and over. If you have only a certain amount of intelligence, a certain personality, and a certain moral character — well, then you’d better prove that you have a healthy dose of them. It simply wouldn’t do to look or feel deficient in these most basic characteristics.

"Beware of success. It can knock you into a fixed mindset: "I won because I have talent. Therefore I will keep winning." Success can infect a team or it can infect an individual."
