What Is Grit? Duckworth's Psychological Definition
Duckworth first defined grit this way in a study introducing the concept as a two-facet personality trait: consistency of interest and perseverance of effort, both aimed at long-term goals.
Consistency of interest means staying committed to the same overarching goal for years, rather than switching from one pursuit to the next as new ideas become more appealing. Perseverance of effort means continuing to work hard toward that goal after the initial excitement fades, when practice becomes routine, or when setbacks make progress feel slow.
Both facets point at the same kind of goal: something that takes years to reach, not a task finished in an afternoon. Duckworth's own research looked at outcomes like completing a demanding multi-year program or reaching an academic milestone, not willpower in a single moment.
This definition is narrower than it might look at first. The everyday sense of grit, courage, toughness, showing strength of character, isn't part of Duckworth's measured construct. Her scale doesn't ask about bravery or emotional fortitude. It asks whether someone's interests stay fixed over time and whether they keep working once a goal stops feeling new. Someone can score high on a grit measure without ever facing a dramatic test of courage, and someone can act bravely in a single moment without necessarily being "gritty" in this specific sense, since one incident doesn't establish a pattern across years.
A lot of popular writing on grit blurs the two meanings together, treating "grit" as a stand-in for general toughness rather than the specific two-facet trait Duckworth actually measured.
Where the Idea Comes From: Duckworth's Research and the Grit Scale
Duckworth was a psychologist at the University of Pennsylvania when she introduced grit, building on an observation from her earlier years as a teacher: some of her most successful students weren't the ones with the highest measured ability, but the ones who kept working the longest.
Her original paper reported on several groups. Cadets at West Point who scored higher on her grit measure were more likely to complete their first summer of training, a demanding period with a high dropout rate, and grit predicted this better than the Whole Candidate Score West Point already used to select applicants. In an Ivy League undergraduate sample, higher grit scores tracked with higher cumulative GPA. And among 175 finalists at the 2005 Scripps National Spelling Bee, grit predicted which round a competitor was eliminated in, even after controlling for verbal IQ.
A follow-up study on the same competition dug into why. Grittier finalists spent more hours in solitary, deliberate practice, studying and memorizing words alone rather than being quizzed by someone else or reading for pleasure, and that practice time is what explained their stronger performance, not some mysterious inner toughness.
To measure grit, Duckworth built a 12-item questionnaire, later called the Grit-O, or "original," covering both facets. In 2009, she and Patrick Quinn published a shorter, 8-item version that keeps the same two-factor structure and correlates strongly with the original. Both ask people to rate general statements about how consistently they pursue goals and how they respond to setbacks, producing a score on the two facets rather than a single pass-or-fail test of grit.
How Grit Differs From Resilience
MindView's own definition of workplace resilience centers on the capacity to recover from a setback and keep functioning, adapting where needed rather than simply pushing through unchanged. Grit and resilience share some territory: both involve continuing to function under difficulty. But a lot of popular writing on grit treats resilience as if it were just one ingredient inside grit, alongside things like passion or conscientiousness, rather than a separate construct with its own research base.
A direct comparison shows why that framing is an oversimplification. A 2022 study followed 4,023 U.S. undergraduates and used statistical modeling to compare how well grit and resilience predicted whether a student re-enrolled the following fall. Across the full sample, the perseverance facet of grit predicted re-enrollment. But when the researchers separated out students with a history of academic probation, the group that had already hit a serious setback, grit's effect no longer held, and only resilience significantly predicted whether they came back.
Grit's effect showed up for students in general, but resilience is what mattered specifically for the students who had already struggled. That's a sharper picture than "resilience is part of grit" or "grit doesn't matter." One way to hold the two ideas apart: grit is about staying consistent, continuing to put effort toward the same goal over a long stretch, while resilience is more about the capacity to recover and adjust after something goes wrong, including changing course if the original plan stops making sense. That's a useful summary rather than a mechanism the research has proven outright, but it matches what the study found: the two traits mattered in different situations, for different students, not as substitutes for each other.
Several of the most-shared explanations of grit online list resilience as simply one of grit's "characteristics." That framing isn't supported by research that measures the two constructs side by side.
Is Grit a Distinct Personality Trait? What the Research Shows
Later research has questioned how distinct grit actually is from personality traits psychologists were already measuring.
A meta-analysis pooling data from 88 samples and more than 66,000 people found that grit correlates very strongly with conscientiousness, one of the well-established Big Five personality traits. The same analysis found that grit's contribution to predicting real-world performance comes almost entirely from the perseverance-of-effort facet; consistency of interest added little on its own. Separately, the largest twin study conducted on grit, covering 2,321 pairs of UK twins, found a genetic correlation of 0.86 between grit and conscientiousness, and concluded that grit added little to predicting academic achievement once conscientiousness and the other Big Five traits were already accounted for.
Duckworth's West Point and Spelling Bee findings haven't been overturned by this later work. What it complicates is the idea of grit as a fully separate personality trait, distinct from traits psychologists already had names for. That specific claim is more contested than a lot of popular coverage suggests, even though sustained effort toward a goal still predicted outcomes in Duckworth's own studies. Treating grit as a singular, freestanding quality that explains success on its own is a bigger claim than the current evidence supports.
What Grit Looks Like in Practice
Duckworth's own research points to concrete, verifiable examples rather than composite or hypothetical ones. The West Point cadets in her study who scored higher on grit were more likely to make it through Cadet Basic Training, the demanding first summer that has historically pushed many candidates to drop out before their first academic year even starts. The Spelling Bee finalists who advanced furthest weren't necessarily the ones with the largest vocabularies walking in; they were the ones who had put in more solitary hours of practice in the months beforehand.
A well-documented example from outside Duckworth's own research illustrates the same two facets, even though nobody measured Wiles on a grit scale. Mathematician Andrew Wiles spent seven years working largely alone, in secret, on a proof of Fermat's Last Theorem, a problem that had gone unsolved for more than 350 years. When a flaw was found in his first announced proof in 1993, he spent roughly another year, working with a former student, correcting it before the proof was accepted. Staying on the same specific goal for years matches consistency of interest; continuing to work through a serious, public setback matches perseverance of effort. That's a description of documented behavior, not a claim about what a grit scale would have measured, and not a manufactured anecdote.
Can Grit Be Built?
Whether grit itself can be taught isn't settled. A nationwide field experiment gave a grit-and-self-regulation program to roughly 33,000 sixth and seventh graders across 350 schools in North Macedonia. The results were mixed: perseverance of effort improved, and disadvantaged students saw GPA gains of up to 28 percent of a standard deviation a year later, but the same program reduced students' consistency of interest, the other facet of grit. Psychology Today's overview of the research states plainly that no one knows for sure whether grit can be taught.
What's better supported is grit's overlap with conscientiousness. Self-discipline, a closely related construct, functions as a trainable skill rather than a fixed trait, and the same small, specific, repeated actions that build it cover much of the same ground as grit's perseverance facet.
Frequently Asked Questions
Is Grit the Same as Mental Toughness?
No, though the terms get used interchangeably in everyday conversation. Mental toughness usually describes performing well and managing emotions under pressure in a specific moment, a framing common in sports psychology, and it can come and go depending on the situation. Grit refers to Duckworth's two-facet trait: sustained interest and effort toward one long-term goal across years. Someone can show mental toughness in a single high-pressure moment without that reflecting the years-long consistency grit measures, and the reverse is also true.
What Are the Synonyms of Grit?
In everyday usage, common synonyms include perseverance, tenacity, fortitude, resolve, and pluck. None of these general synonyms map exactly onto Duckworth's specific two-facet definition; they describe a similar quality in ordinary language, not the measured psychological construct covered in this article.
What Is the Grit Scale, and Can You Test Your Own Grit?
The Grit Scale is a self-report questionnaire Duckworth developed to measure consistency of interest and perseverance of effort. The original 12-item version, the Grit-O, appeared in her 2007 paper. An 8-item short version, the Grit-S, published by Duckworth and Patrick Quinn in 2009, correlates closely with the original and takes less time to complete. Both are available through the sources in the references below rather than reproduced here, since MindView isn't the instrument's publisher.
Grit and Resilience Are Both Worth Understanding, Not Just One
The distinction matters because these two ideas call for different responses. Sustained effort toward a long-term goal, and the capacity to recover and adjust after a setback, aren't the same skill, and treating them as interchangeable can lead to the wrong advice at the wrong moment.
MindView's own work is built around the second idea: giving people a structured, repeatable way to practice staying steady and adjusting under pressure, using VR training connected to a mobile app and biometric preparation. That connected core is established and already in use. Specific new scenarios, including an expanded café environment and a new subway-based training track, along with further mobile and dashboard tools, are still in active development. None of this is framed around "grit" as a named feature. It's the same underlying idea this article has been describing: the capacity to recover from a setback is something people can practice, not just something they either have or don't.
