Grit: The Power of Passion and Perseverance

Miles: Every July, roughly twelve hundred new cadets arrive at West Point for seven weeks of training the Academy nicknames Beast Barracks. These are people who survived years of selection. And every year, a meaningful number of them quit before the summer ends. The Academy has an admissions formula built from test scores, class rank, leadership, and physical fitness, and that formula doesn't predict who quits.

Miles: A researcher shows up with a twelve question survey that takes about three minutes. It does predict it.

Miles: Today: Grit, by Angela Duckworth. In two sentences: sustained achievement comes less from talent than from passion and perseverance held steadily over years. Effort counts twice, because it builds the skill and then it produces the result.

Miles: Sixty Books. Presented by Stoar Consulting and Coaching.

Miles: Welcome back to the reading room. Miles talking. Sixty Books, and the format holds: one management book per show, sixty of the strongest the past century produced, read for leaders and teams who think differently, and for work where AI now sits inside the job. Nora has the studies.

Miles: Nora, this is the book with the largest gap between how famous it is and how well it's held up.

Nora: And the gap is documented rather than a matter of opinion, which is what makes this episode worth doing.

Miles: Start with the research.

Nora: Duckworth's early work looked at settings where dropping out was measurable and consequential. West Point. Rookie teachers in tough schools. Salespeople. And the Scripps National Spelling Bee, which is a beautiful natural experiment because you can measure hours of practice, verbal ability, and outcome all at once.

Miles: And the finding.

Nora: In each case her grit measure predicted who stayed and who finished, and it did so on top of, or sometimes in place of, the measures the institution was already using. At the Bee, the grittier children practiced more, and the kind of practice they did, alone and deliberate rather than pleasant, predicted how far they went.

Miles: Define grit as she does.

Nora: Passion and perseverance for long term goals. And she's specific that passion here doesn't mean enthusiasm or intensity. It means consistency. Caring about the same thing for years.

Miles: The formula.

Nora: Talent times effort equals skill. Skill times effort equals achievement. Hence her line that effort counts twice. It isn't a real equation, and she says so, but the point is that talent is a rate of improvement rather than a destination.

Miles: The author, because her biography is doing work in this book.

Nora: Angela Duckworth, born nineteen seventy, daughter of Chinese immigrants. She studied neurobiology at Harvard, won a Marshall Scholarship, went to Oxford, and then went into management consulting at McKinsey.

Miles: And left.

Nora: For teaching. She taught mathematics to seventh graders in public schools, and it was there that she noticed that her best students weren't always the ones with the highest measured ability. She went back for a doctorate at Penn at thirty two, under Martin Seligman.

Miles: And there's a line from her childhood that runs through the whole book.

Nora: Her father used to tell her she was no genius. Repeatedly. It clearly stung, and it's the reason the book is fixated on the question of whether talent is the thing that matters.

Miles: And then the punchline.

Nora: In twenty thirteen she was awarded a MacArthur Fellowship, which everyone calls the genius grant. She's said, drily, that she thought of her father when the call came.

Miles: The book.

Nora: Twenty sixteen, enormous bestseller, and she also founded a nonprofit called Character Lab. And I want to say clearly that Duckworth is a serious researcher who's been more candid about the limits of her own work than almost anyone on this shelf. That matters for what comes next.

Miles: Take me through the structure.

Nora: Two halves. Growing grit from the inside out, and from the outside in. The inside out half has four psychological assets, in developmental order. Interest, practice, purpose, and hope.

Miles: Interest first.

Nora: And this is the part most people skip, which is a shame, because her claim is that passion is discovered rather than chosen. It comes from a period of unstructured play and exposure, then a triggering encounter, then years of development. Nobody arrives knowing.

Miles: Right. Practice.

Nora: Deliberate practice, from Ericsson, which we covered in episode four. Stretch goal, full concentration, immediate feedback, repetition with refinement. And her plain admission is that this kind of practice doesn't feel good while you're doing it.

Miles: Purpose.

Nora: The idea that interest becomes durable when it connects to other people's wellbeing. Her claim is that gritty people almost universally describe their work as serving something beyond themselves, and that this is what sustains them past the point where enjoyment would have run out.

Miles: Hope.

Nora: Not optimism that things will go well, but the belief that your own effort can improve your future. Which leans directly on the next book we're doing.

Miles: There are two more ideas I want before the outside in half.

Nora: The first is the naturalness bias, and it's the most uncomfortable finding in the book. The psychologist Chia-Jung Tsay ran studies with professional musicians. They were given recordings alongside descriptions of the performer, one framed as a natural talent, the other as someone who got there through hard work.

Miles: And the experts preferred.

Nora: The natural, consistently, even though they had said in the abstract that they valued effort more. Their stated values and their actual judgments went in opposite directions, and they didn't notice.

Miles: Which is directly our territory.

Nora: It is, because it explains a specific and common experience. A neurodivergent professional who visibly works at something the rest of the room finds effortless gets read as less able, even when the output is equal or better. The visible effort is itself the penalty.

Miles: The second idea.

Nora: The goal hierarchy. Duckworth argues that gritty people have a pyramid: one top level goal that's essentially permanent, a small number of mid level goals serving it, and many low level goals that are disposable. And the crucial move is that low level goals are supposed to be abandoned freely when they stop serving the level above.

Miles: So consistency is only required at the top.

Nora: Which quietly contradicts her own scale. The questionnaire penalizes changing projects. The theory says changing projects is correct as long as the top goal holds. A person who has tried six careers in service of one durable question is gritty under the theory and ungritty under the measurement.

Miles: And that resolves something for our audience.

Nora: It gives a person with a scattered looking history a legitimate question to ask. Not have I stuck at things, but is there one thing underneath all of them. Very often there is, and nobody's ever asked.

Miles: And the outside in half.

Nora: Parenting, which she frames as supportive and demanding at once rather than one or the other. A rule she calls the Hard Thing Rule, where everyone in the family does something difficult that requires deliberate practice, you may not quit on a bad day, and you may quit at a natural stopping point. And cultures of grit, where she looks at organizations that make persistence the identity rather than the instruction.

Miles: Now the neurodivergent read, and I want to start with the measurement, because this is where it gets sharp.

Nora: The Grit Scale has two facets. Perseverance of effort, and consistency of interest. And the consistency of interest items are things like: I often set a goal and later choose to pursue a different one. New ideas and projects sometimes distract me from previous ones. My interests change from year to year.

Miles: Read those again slowly, because that's a screening instrument.

Nora: They're close to diagnostic items for ADHD. The scale is measuring interest shifting and scoring it as a character deficiency. And a person with ADHD who answers that questionnaire accurately will score low on grit while possibly having ferocious perseverance inside whatever currently holds their attention.

Miles: And what does the evidence say about that facet?

Nora: This is the part I find genuinely satisfying. In twenty seventeen, Credé, Tynan, and Harms published a meta analysis in the Journal of Personality and Social Psychology. Five hundred and eighty four effect sizes, eighty eight samples, sixty six thousand eight hundred and seven people.

Miles: And.

Nora: The two facets don't perform equally. Perseverance of effort correlated with academic performance at about point two six. Consistency of interest, at about point one zero.

Miles: So the facet that penalizes neurodivergence is the facet that barely predicts anything.

Nora: It's the weakest part of the construct, and it's the part doing the moral work. If you drop it, grit becomes perseverance, which is real and which many neurodivergent people have in abundance when the conditions are right.

Miles: What else did that meta analysis find?

Nora: Three things, and together they're close to a demolition. The higher order structure of grit wasn't confirmed, meaning the two facets don't behave like one trait. Grit's correlation with performance is modest overall, around point one eight for academic performance. And grit correlates with conscientiousness, the long established personality trait, at about point eight four.

Miles: Yeah. Point eight four.

Nora: Which in this field means you may be measuring the same thing with a new name. Their conclusion was that grit adds essentially no predictive power for academic performance beyond conscientiousness, and that interventions designed to build grit are likely to have weak effects.

Miles: So what survives?

Nora: Perseverance of effort, which was already known and which the meta analysis found predicts performance even after controlling for conscientiousness. Interest as a discovered rather than chosen thing, which is well supported elsewhere. And purpose and hope, which aren't really grit claims at all.

Miles: Say the rest of the neurodiversity turn, because the measurement problem isn't the only one.

Nora: The bigger risk is what grit becomes in a manager's hands. It's a moral vocabulary for effort, and moral vocabularies get used to deny support. If persistence is a virtue and you're struggling, then the diagnosis is insufficient virtue, and the remedy is trying harder, which is precisely what a great many neurodivergent adults have been told since childhood while trying extremely hard.

Miles: To be fair to her.

Nora: To be entirely fair, Duckworth has publicly opposed grit being used for school accountability and has resisted the idea that it should be scored and ranked. The misuse isn't her design. It's what happens when a construct with moral flavor meets an institution that wants a number.

Miles: There's a cultural chapter too.

Nora: Where she looks at organizations that build persistence into identity rather than instruction. A professional football team under Pete Carroll, the finishing culture at West Point, and the Finnish concept of sisu, a national word for stubborn endurance.

Miles: And the mechanism she claims.

Nora: That it's easier to become gritty by joining a group where that's simply what people do than by resolving to be gritty alone. Which is probably the most defensible claim in the book, because the behavior is being carried by the environment rather than by daily willpower, which is the argument this show has landed on since episode two.

Miles: And a caution for us.

Nora: The same mechanism produces the strongest pressure to mask. A culture built on visible endurance rewards people who never appear to struggle, and the cost of appearing to struggle is highest for the person who already stands out.

Miles: What's worth keeping?

Nora: Three things. Interest precedes perseverance, which for an interest driven attention system isn't a nice idea but the entire operating principle. Purpose sustains effort past enjoyment, which is true and useful. And the Hard Thing Rule contains a good distinction: you may not quit on a bad day, but you may quit at a natural stopping point. That separates leaving because today is unbearable from leaving because the fit is wrong, and the second one is what episode seven called match quality.

Miles: What kind of book is it, then?

Nora: A serious researcher's popular book, resting on a construct that a large meta analysis found to be mostly conscientiousness wearing a better outfit, with one facet that survives and one that penalizes exactly the people this show is about.

Miles: Fair enough.

Miles: Here's the recap, in the frame we work in. Grit says passion and perseverance held over years beat talent. For anyone leading neurodivergent people, or leading as one, this is what it comes down to in practice. Keep perseverance of effort and discard consistency of interest, because the evidence says the second one barely predicts anything while punishing a difference. Treat interest as the precondition rather than the reward, because that's where perseverance actually comes from. Watch for grit language being used as a reason not to change conditions. And keep the distinction between quitting on a hard day and leaving a bad fit, because only one of those is a failure.

Miles: And the part with the chat window.

Nora: Grit's mechanism is sustained effort, and the useful question is which parts of effort are worth sustaining. Before that, one piece of housekeeping: what we used to say here is set into the tail of the episode now, in one wording that doesn't move.

Miles: Please.

Nora: Deliberate practice needs immediate feedback, and that's always been the scarce ingredient, because it usually required a coach. A model can supply an approximation of that instantly, at any hour, for a great many skills. That's a real change to Ericsson's conditions rather than a convenience.

Miles: And the interest side.

Nora: The book says interest develops through exposure and a triggering encounter. Lowering the cost of exploring a new field, of getting a competent overview of something before you know whether you care, makes that exposure period cheaper. Which matters most for the person who can't get access to the field any other way, as we said about hours in episode four.

Miles: The dangers.

Nora: Two. The first is that grit's whole claim is about tolerating the unglamorous middle, and a tool that removes the unglamorous middle may also remove the thing that was building the capacity. That's the same caution we gave about scaffolding in episode eight. And the second is subtler. If you never have to persist, you never learn that you can, and hope in Duckworth's sense is built from evidence about yourself.

Miles: So the line to keep.

Nora: Effort counts twice, she says. Let the tool take the first count if you like, the skill building drudgery, but the second one, the part where you find out you can finish, is the one nobody can run for you.

Miles: That's Grit.

Miles: Next time: Mindset, by Carol Dweck, the book that gave every school in the country a poster, and what happened when the effect was measured at scale.

Nora: Three hundred and sixty five thousand students in the biggest test. The poster doesn't know about that yet.

Miles: Thanks for that, Nora.

Nora: Always, Miles.

Miles: Okay. Next book.

Miles: Behind Sixty Books is Stoar Consulting and Coaching. Logan Williamson is a Licensed Professional Counselor in Texas and Louisiana. This episode was education, a book read for the benefit of leaders and teams. Coaching, no. Counseling, no. And it carried no view of you.

Nora: Every claim today has a citation on the episode page, right by the transcript. A new book arrives tomorrow.

Miles: One last thing. Miles is synthetic. So is Nora. No license, no person, and nothing here was aimed at you. AI assistance goes into every script, and Logan Williamson, a Licensed Professional Counselor in Texas and Louisiana, at Stoar Consulting and Coaching, has edited and approved it.

Nora: And one note about the AI segment. The evidence that these tools help neurodivergent people at work is early. There are controlled trials now, but they measure things like conversation skill rather than how a job actually goes, and for work itself most of what exists is individual providers reporting success. So take it as promising and not proven. The tools also get rebuilt every few months, so whatever you set up today is built on something that moves.
