So children with the fixed mindset want to make sure they succeed. Smart people should always succeed. But for children with the growth mindset, success is about stretching themselves. It’s about becoming smarter.

Not long ago I was interested to read about Marina Semyonova, a great Russian dancer and teacher, who devised a novel way of selecting her students. It was a clever test for mindset. As a former student tells it, “Her students first have to survive a trial period while she watches to see how you react to praise and to correction. Those more responsive to the correction are deemed worthy.”

In other words, she separates the ones who get their thrill from what’s easy - what they’ve already mastered - from those who get their thrill from what’s hard.

It’s also important to realize that even if people have a fixed mindset, they’re not always in that mindset. In fact, in many of our studies, we put people into a growth mindset. We tell them that an ability can be learned and that the task will give them a chance to do that. Or we have them read a scientific article that teaches them the growth mindset. The article describes people who did not have natural ability, but who developed exceptional skills. These experiences make our research participants into growth-minded thinkers, at least for the moment - and they act like growth-minded thinkers, too.

The students with growth mindset completely took charge of their learning and motivation. Instead of plunging into unthinking memorization of the course material, they said: “I looked for themes and underlying principles across lectures,” and “I went over mistakes until I was certain I understood them.” They were studying to learn, not just to ace the test. And, actually, this was why they got higher grades—not because they were smarter or had a better background in science.

Instead of losing their motivation when the course got dry or difficult, they said: “I maintained my interest in the material.” “I stayed positive about taking chemistry.” “I kept myself motivated to study.” Even if they thought the textbook was boring or the instructor was a stiff, they didn’t let their motivation evaporate. That just made it all the more important to motivate themselves.

So telling children they’re smart, in the end, made them feel dumber and act dumber, but claim they were smarter. I don’t think this is what we’re aiming for when we put positive labels - “gifted,” “talented,” “brilliant” - on people. We don’t mean to rob them of their zest for challenge and their recipes for success. But that’s the danger.
