The Truth About Ability and Accomplishment

Mindsets in School and Early Life

“Praising children’s intelligence harms their motivation and it harms their performance.” — Carol S. Dweck

Nowhere are the effects of mindsets more consequential—or more observable—than in education. Schools are where most of us first encounter the labels of “smart” and “not smart,” where the fixed mindset often takes hold, and where the right or wrong messages from adults can set children on trajectories that last a lifetime. This chapter brings Dweck’s research to its most practical and urgent ground: how do mindsets affect learning, and what can parents, teachers, and society do about it?

The Problem with Labeling Children “Smart”

A Landmark Experiment on Praise

Dweck and her colleague Claudia Mueller conducted what became one of the most influential studies in educational psychology. They took fifth-grade students and had them complete a set of moderately difficult puzzles. After the first round, they praised all students—but with a twist. Some students were told, “Wow, you got eight right. That’s a really good score. You must be smart at this.” Others were told, “Wow, you got eight right. That’s a really good score. You must have worked really hard.”

The same performance, praised in two entirely different ways. Then the researchers gave students a choice of follow-up tasks: they could do a harder set of problems (which they’d learn from) or an easier set (which they could definitely do well on). Nearly 90% of the students praised for effort chose the harder set. The majority of students praised for intelligence chose the easier set.

After another round of (deliberately harder) problems where all students struggled, the differences were even more dramatic:

A single dose of praise—“you’re smart” versus “you worked hard”—had created measurable differences in motivation, persistence, and performance.

What the “Smart” Label Does

The Tyranny of the Gifted Label

When we tell children they are smart, we are—without intending to—implying that intelligence is a fixed quality they happen to possess. This creates several problems:

They feel they must live up to the label. If you’re smart, you should perform well. Struggling or making mistakes becomes a threat to the label—and therefore to your sense of self.

They become risk-averse. To protect the “smart” label, they avoid challenges where they might not look smart. They choose easier tasks, avoid domains where they might fail, and disengage from subjects that require real struggle.

They stop working as hard. If success is supposed to be effortless for smart people, then effort becomes evidence that you’re not as smart as the label claims. Many gifted students develop a troubling pattern: they do well as long as material comes easily, but disengage the moment it requires real work.

They attribute failure to character. When they struggle or fail, they don’t think “I need to try harder” or “I need a better strategy”—they think “I’m not as smart as everyone thought.”

The Better Praise

Growth mindset praise focuses on process rather than person:

This kind of praise helps children understand that their achievement came from their effort and approach—things they can control and continue to develop.

Mindsets and Educational Achievement

The Resilience Gap

Students with growth mindsets are significantly more resilient than those with fixed mindsets when they encounter academic difficulty—and academic difficulty is inevitable. Every student, at some point in their education, will encounter subjects that don’t come easily, teachers who are harder to please, or transitions (like moving from elementary to middle school) that disrupt their previous patterns of success.

Dweck and colleague Lisa Blackwell followed students through the transition to seventh grade—a period when many students’ grades decline as the work gets harder. Students with growth mindsets showed much less of a performance drop. And when they did struggle, they responded by working harder, seeking help, and trying new strategies. Students with fixed mindsets were more likely to disengage, decide they were “not a math person” (or whatever subject was difficult), and give up on that domain.

The “Not Yet” Research

In one of Dweck’s most famous and widely replicated findings, students who received the grade “Not Yet” for failing a course—rather than a traditional failing grade—showed dramatically different responses than students who received “F.” The concept of “Not Yet” implies that you’re on a learning journey, that your current performance isn’t a final verdict but a point on a continuum.

Students given “Not Yet” grades showed more persistence, greater effort, and better long-term outcomes. The words we use to describe failure matter enormously because they shape what children believe that failure means.

The Toxic Belief: “I’m Not a [Math/Science/Art] Person”

Fixed Identity Statements

One of the most damaging consequences of fixed mindset thinking in education is the proliferation of fixed identity statements—“I’m just not a math person,” “I’ve never been good at science,” “I’m not creative.” These statements close off domains of learning and growth permanently. Once children (or adults) decide they lack a fixed trait in a particular area, they stop trying. And since they stop trying, they never develop the ability they assumed they didn’t have—creating a self-fulfilling prophecy.

Dweck notes that in the United States especially, it’s socially acceptable to claim inability in mathematics in a way that it simply isn’t for reading. “I can’t read” carries social stigma. “I’m not a math person” is treated as a harmless personality quirk—even worn as a badge of identity. This cultural acceptance of mathematical inability, she argues, has real consequences for how many students disengage from STEM education.

In Japan and China, by contrast, the dominant cultural belief is that mathematical ability is developed through hard work rather than innate talent—and those countries show higher mathematical achievement at the population level.

Stereotype Threat and the Mindset Connection

How Labels Undermine Performance

Researcher Claude Steele identified a phenomenon called stereotype threat: members of groups that are negatively stereotyped in a particular domain (like women in mathematics, or Black students in academic achievement generally) underperform in that domain partly because they are aware of the negative stereotype and anxious about confirming it.

Dweck found that mindset interventions can reduce stereotype threat. When students understand that intelligence is malleable and that struggle is a normal part of learning, the anxiety associated with being a member of a stereotyped group decreases. They’re no longer trying to disprove a fixed deficit—they’re on a learning journey like everyone else.

In one study, simply teaching students about the growth mindset—showing them that the brain, like a muscle, grows stronger with use—led to significant improvements in motivation and performance among students from groups vulnerable to stereotype threat.

The Growth Mindset Curriculum

Teaching the Developing Brain

Dweck collaborated with educational researchers to develop curriculum that explicitly teaches students about the growth mindset and the neuroscience of learning. Key elements included:

Schools that implemented this curriculum saw significant improvements in student motivation, persistence, and achievement—particularly among students who had previously been low achievers.

Reflection

Think about your own educational experiences. Were you praised for being “smart” or for working hard? Were there subjects where you decided early on that you “weren’t that kind of person”? How might those early experiences be shaping your approach to learning today?
