The word “grit” used to just mean toughness. Then, in 2007, a psychologist gave it a precise scientific definition. Almost overnight, the grit meaning most people use today became one of the most cited ideas in psychology, and one of the most argued-about.
So what does grit actually mean? Here is the original research, the two parts it’s built from, and the criticism that most short explainers leave out.
Quick Answer: The Grit Meaning, Defined
Grit is a psychological trait defined by psychologist Angela Duckworth as “perseverance and passion for long-term goals.” It combines two things: staying interested in a goal over years, not weeks, and continuing to work hard even after setbacks, boredom, or failure. Grit is not the same as raw willpower or talent. It is a sustained pattern of effort aimed at one long-term target.
Key Takeaways
- Grit was formally defined in 2007 by Angela Duckworth and colleagues in the Journal of Personality and Social Psychology.
- It has two parts: passion and perseverance. Passion means sticking with the same goal over time. Perseverance means pushing through setbacks toward it.
- Grit predicted success independent of IQ in the original studies, across cadets, spelling bee competitors, and Ivy League students.
- It strongly overlaps with conscientiousness, a well-known Big Five personality trait, which is the center of most academic criticism of the concept.
- Grit explained only about 4% of the difference in achievement outcomes across the original samples. That’s real, but modest.
- Critics argue grit can tip into a downside: tunnel vision, burnout, and staying too long on the wrong goal.
The Original Grit Meaning: Duckworth’s 2007 Definition
The grit meaning used in psychology today comes from a 2007 paper. Angela Duckworth wrote it with Christopher Peterson, Michael Matthews, and Dennis Kelly. Their definition: “perseverance and passion for long-term goals.”
The study tested that idea across a wide mix of people:
| Group studied | Sample size |
|---|---|
| Adult samples (general population) | 1,545 and 690 |
| Ivy League undergraduates | 138 |
| U.S. Military Academy cadets (two classes) | 1,218 and 1,308 |
| National Spelling Bee competitors | 175 |
Across all of them, grit had no link to IQ. Yet it still told you who stuck with a hard goal and who quit. That included which cadets made it through the Academy’s brutal first summer, and which spelling bee kids went the furthest.
The Two Parts of Grit
Grit isn’t just stubbornness. It’s built from two parts, and both matter.
Passion means sticking with the same big goal for years, not jumping to the next shiny thing. This doesn’t mean you never change your path. It means the destination stays the same, even as the route shifts.
Perseverance means you keep trying after setbacks, boredom, or flat-out failure. It’s the part most people think of first when they hear the word “grit.”
Neither part works alone. Passion with no perseverance is just a hobby people quit at the first hard part. Perseverance with no passion is hard work with no real direction behind it.
How Grit Differs From Related Traits
Grit shares real ground with older, well-known ideas in psychology. That overlap is exactly where most of the debate comes from.
- Conscientiousness is a broad trait that covers discipline in general, from tidiness to punctuality. Grit is more narrow. It’s aimed only at long-term goals.
- Self-control is about resisting a temptation right now, in the moment. Grit is about staying the course for months or years, a much longer timescale.
- Willpower describes a short burst of effort. Grit describes a pattern that holds up over a far longer stretch of time.
The original 2007 study found grit tracked closely with conscientiousness. Still, it predicted success even after conscientiousness was factored out. That single fact is the whole reason to treat grit as its own trait, not just a new name for an old one.
What Critics Say (The Part Most Articles Skip)
Grit became famous fast. Duckworth’s 2013 TED talk and her 2016 bestselling book saw to that. Fame invited scrutiny, and the scrutiny raised real, fair points.
The effect is small. In the original studies, grit explained only about 4% of the gap in achievement outcomes. That’s a real finding. Still, it’s far from the whole story of why some people succeed and others don’t.
Later studies found grit adds little beyond conscientiousness. A widely cited 2016 review found that once you measure conscientiousness, grit’s perseverance part barely adds anything new on top. The passion part fared even weaker.
Grit can tip into a downside. Psychology Today notes that a narrow, intense focus on one goal can breed tunnel vision, burnout, and fatigue. That’s especially true when the goal turns out to be the wrong one to chase.
Success needs more than grit. Access, opportunity, and plain luck shape outcomes too. Treating grit as the main reason people succeed risks blaming individuals for barriers that no amount of hard work can fix alone.
None of this erases the original finding. It just means grit explains a real, but limited, slice of why people succeed. Not the whole picture.
Grit Meaning in Practice: How to Build It
If the grit meaning above is a pattern of effort rather than a fixed trait, it can be built. A few evidence-informed starting points:
- Try more things before committing. Passion is often found through exposure, not decided on in advance. Sampling widely makes the eventual choice more durable.
- Reframe failure as information. Duckworth’s research treats setbacks as data about what to adjust, not proof the goal was wrong.
- Surround yourself with gritty people. Both Duckworth’s research and later commentary point to environment as a real lever: perseverance is easier to sustain around people who model it.
- Build a growth mindset alongside it. Believing ability can improve with effort makes it easier to keep going after a setback instead of concluding the goal is out of reach.
- Watch for the downside. Because critics are right that grit can turn into tunnel vision, check in periodically on whether the goal itself still makes sense, not just whether you’re still working hard toward it.
Frequently Asked Questions About Grit Meaning
What is the simplest definition of grit?
Grit is perseverance and passion for long-term goals, a definition set by psychologist Angela Duckworth in 2007. It means staying committed to one goal over years, and continuing to put in effort even after setbacks.
Who came up with the concept of grit?
Angela Duckworth, along with Christopher Peterson, Michael Matthews, and Dennis Kelly, defined grit in a 2007 study. Duckworth later popularized it further through a 2013 TED talk and her 2016 book, Grit: The Power of Passion and Perseverance.
Is grit the same as conscientiousness?
No, though the two overlap heavily. Conscientiousness is a broad trait covering discipline and organization in general. Grit is narrower, aimed specifically at one long-term goal. Critics say the overlap is large enough that grit adds only a modest amount beyond conscientiousness alone.
More Grit Meaning Questions
Can grit actually be learned?
Duckworth’s research treats grit as something that can grow, not a fixed trait you’re born with. Trying new things, treating failure as feedback, and staying around people who model perseverance are the most common paths to building it.
What are the criticisms of the grit concept?
The main criticisms: grit’s effect on achievement is small, later studies found it adds little beyond conscientiousness, and an intense focus on one goal can lead to burnout if that goal turns out to be the wrong one.
Does grit predict success better than IQ?
In Duckworth’s original studies, grit was unrelated to IQ but still predicted real outcomes, like who stayed through Military Academy training and who advanced furthest in the Spelling Bee. Still, grit explained only a modest share of the difference, so it adds to other predictors of success rather than replacing them.
Bottom Line: The Grit Meaning That Actually Holds Up
Grit means perseverance and passion for long-term goals, a definition with real research behind it dating to 2007. It is genuinely useful. Still, the honest version of the story includes the pushback: the effect is smaller than its fame suggests, and it overlaps heavily with older, well-studied traits like conscientiousness.
Used as one input rather than the whole story, grit still holds up well. Used as a stand-in for opportunity, support, and the right goal in the first place, it doesn’t.
