True Grit - Can Perseverance be Taught? - Angela Lee Duckworth at TEDxBlue
-
0:09 - 0:12I'm a psychologist and I study achievement.
-
0:12 - 0:16Most psychologists who study
achievement study intelligence. -
0:16 - 0:20And if the last talk didn't convince you
-
0:20 - 0:23and I have a suspicion you didn't
need a whole lot of convincing, -
0:23 - 0:26intelligence is, there's only part of the story,
-
0:26 - 0:30maybe a very small part of the story.
-
0:30 - 0:32And it is, in fact possible that we even have
-
0:32 - 0:34that small part of the story wrong.
-
0:34 - 0:37In terms of intelligence being thought to be
-
0:37 - 0:40something largely inherited and not developed.
-
0:40 - 0:45Something that is relatively immutable
over the course of one's life. -
0:45 - 0:50But I came to a study of all the other
things that intelligence, -
0:50 - 0:54everything else, that made up achievement.
-
0:54 - 0:59In kind of a circuitous route --
so I was 32 when I started graduate school. -
0:59 - 1:01You know, I turned to my left and to my right and
-
1:01 - 1:04everybody else was drinking cappuccino and studying at
-
1:04 - 1:08one in the morning because they were 22, not 32.
-
1:08 - 1:12And so, I actually think my
life story is a great example -
1:12 - 1:15of actually not have grit,
not having enough grit. -
1:15 - 1:17Maybe some talent but not actually having --
-
1:17 - 1:20What I now study is one of the key and
-
1:20 - 1:24probably necessary ingredients of high achievement
-
1:24 - 1:27in any field that you want to consider.
-
1:27 - 1:30So, what I did between the age of 22 and 32 was many
-
1:30 - 1:33different things all of which I think
sounded good on a resume. -
1:33 - 1:36I was a McKinsey Consultant, I went to Oxford
-
1:36 - 1:39for a couple of years on a prestigious fellowship.
-
1:39 - 1:44I was the COO of a non-profit website for parents
-
1:44 - 1:46to get school information that sounds good,
-
1:46 - 1:49that was good, sounds good and was good.
-
1:49 - 1:53I taught in various schools in New York
-
1:53 - 1:55and in Philadelphia and in San Francisco.
-
1:55 - 1:59And all this added up to
a great person to have dinner with -
1:59 - 2:03because that person, had done
a lot of interesting things -
2:03 - 2:07and have done most of those
things actually relatively well. -
2:07 - 2:10But what I realized is that if you are a boat,
-
2:10 - 2:14a really fast, shiny boat,
which is going quickly towards -
2:14 - 2:18one destination but then
tacks to another direction, -
2:18 - 2:21to go to another port, and then tacks again --
-
2:21 - 2:26Essentially you end up being a really
shiny boat that goes fast nowhere. -
2:26 - 2:28And, so my own kind of personal experience
-
2:28 - 2:30and probably my lack of grit, actually,
-
2:30 - 2:34led me to study this quality in some detail.
-
2:34 - 2:37And I'm gonna mention,
something that I'll get to -
2:37 - 2:40later in the talk but it's called the "10 year rule."
-
2:40 - 2:44It turns out that there is really no domain of expertise
-
2:44 - 2:47that has been studied where the world class performers
-
2:47 - 2:51have put in fewer than 10 years of consistent,
-
2:51 - 2:53deliberate practice to get to where they are.
-
2:53 - 2:56So, I started graduate school in 2002 --
-
2:56 - 2:59I have three more years on my clock -- which means
-
2:59 - 3:01many things, among which means I can't give up until
-
3:01 - 3:04I have at least put in my 10 years and see,
-
3:04 - 3:07whether I've gotten anywhere.
-
3:07 - 3:10Psychologist have been interested in the distinction
-
3:10 - 3:14between talent and everything else for years.
-
3:14 - 3:16Right? So, before we had words to describe it
-
3:16 - 3:18we were also probably interested in it.
-
3:18 - 3:21But here is a quote from Clark Hall, one of the eminent
-
3:21 - 3:24American psychologist of the early 20th century.
-
3:24 - 3:27He wrote a little review, he kind of reviewed the literature
-
3:27 - 3:29that was out there, which was quite easy to do in 1928,
-
3:29 - 3:31there was a whole lot less of it.
-
3:31 - 3:33He said, you know there are really two things:
-
3:33 - 3:37there's our talent and I would emphasize what
-
3:37 - 3:40Chris said, talent is multifaceted, there's creativity,
-
3:40 - 3:43there's visual creativity, that different from musical creativity,
-
3:43 - 3:45there's analytical talent, there's athletic talent,
-
3:45 - 3:47there is musical talent.
-
3:47 - 3:49But let's put them all on one category.
-
3:49 - 3:52There's intelligence as conventionally defined,
-
3:52 - 3:54and then there are all those many things that are
-
3:54 - 3:57so much worse understood in a way,
-
3:57 - 4:01all the capacities that allow us to unlock our talents and
-
4:01 - 4:04he would put those in the category of industry.
-
4:04 - 4:05William James made the same distinction.
-
4:05 - 4:10William James wrote a famous essay
in 1907 called, "The Energies of Men," -
4:10 - 4:13and William James who arguably is the founder of
-
4:13 - 4:16American psychology said there are our talents and
-
4:16 - 4:19those things that unlock our talents and we could design
-
4:19 - 4:22all of psychology to try to understand these two things.
-
4:22 - 4:25I would argue that we've done
some amount of work on the -
4:25 - 4:30talents and almost nothing on the unlocking.
-
4:30 - 4:33When I considered what is it that unlocks people's
-
4:33 - 4:38potential, what enables people
to become a world class musician, -
4:38 - 4:42a world class teacher,
a world class performer. -
4:42 - 4:48I struggled with this word
to call what I was becoming -
4:48 - 4:50to understand was one of these key ingredients.
-
4:50 - 4:54Eventually I called it grit, which I named in part after the
-
4:54 - 4:58somewhat mediocre western John Wayne starred in;
-
4:58 - 5:01I'll say a little more about that
but, the reason why I came -
5:01 - 5:06to this concept of grit was
I interviewed people that I knew -
5:06 - 5:08that were at the tops of their fields,
-
5:08 - 5:09so it was relatively opportunistic.
-
5:09 - 5:12I mean I interviewed my friend
who had won a MacArthur, -
5:12 - 5:14I interviewed investment bankers
-
5:14 - 5:17who at least at that time were very successful.
-
5:17 - 5:21I interviewed, musicians and professors, and alike.
-
5:21 - 5:23And people would often say, the people who are
-
5:23 - 5:26top in my field are the really talented ones.
-
5:26 - 5:28But just as often, and in fact I would say more often,
-
5:28 - 5:31people said that these individuals at the top of
-
5:31 - 5:35their fields had this kind of tenacious, dogged
-
5:35 - 5:38perseverance unlike anyone else that they knew and
-
5:38 - 5:41it was actually that which
vaulted them to the to the top. -
5:41 - 5:44So I called it "true grit" after this movie which is
-
5:44 - 5:48really about a young girl from Yale County, Arkansas
-
5:48 - 5:52who like in typical western form,
her father is unjustly murdered, -
5:52 - 5:54she spends the rest of the movie avenging his death,
-
5:54 - 5:58and Rooster Cogburn plays the one-eyed,
-
5:58 - 6:01semi-alcoholic sheriff who follows her along.
-
6:01 - 6:03And everyone thinks that true grit is really about
-
6:03 - 6:06John Wayne, of course,
and it's really about this young -
6:06 - 6:09girl who against all odds
pursues a very long term, -
6:09 - 6:13almost impossible goal and eventually --
-
6:13 - 6:17with the emphasis on eventually, succeeds in that goal.
-
6:17 - 6:21And this is the quality that I study.
-
6:21 - 6:24Charles Darwin had a half cousin named Francis Galton,
-
6:24 - 6:27and they shared a correspondence.
-
6:27 - 6:33I like to think that correspondence today is as rich and
-
6:33 - 6:36personally reveling as it was
when you had to put a pen to paper. -
6:36 - 6:38So, maybe if they had emailed they would have shared
-
6:38 - 6:40the same kinds of conversations.
-
6:40 - 6:43This conversation, this quote, this is actually the letter on
-
6:43 - 6:46the left and, maybe a little more legible on the right,
-
6:46 - 6:48was Charles Darwin's response to Francis Galton
-
6:48 - 6:51who had written a book called "Hereditary Genius."
-
6:51 - 6:55Francis Galton made the claim that genius had 3 parts:
-
6:55 - 7:01one part talent, one part passion
or zeal and one part hard work. -
7:01 - 7:03And Charles Darwin's response to that was,
-
7:03 - 7:06"That's a really interesting idea,
I thought it was all -
7:06 - 7:10the hard work and the passion,
maybe there's a role for talent after all." -
7:10 - 7:12Charles Darwin himself didn't actually consider
-
7:12 - 7:14his intellect to be at all special.
-
7:14 - 7:16He thought he had a quite ordinary mind.
-
7:16 - 7:24But a very specific interest and focus
and a lot of zeal and hard work. -
7:24 - 7:29Moving up a little closer to where we are in time,
-
7:29 - 7:32there was a graduate student
at Stanford named Katherine Cox, -
7:32 - 7:35she was a graduate student of a professor
there named Lewis Termin, -
7:35 - 7:38he gave us, possibly the most widely used
-
7:38 - 7:40intelligence test today, the Sanford-Binnet IQ test.
-
7:40 - 7:43She was doing her graduate work in a lab where
-
7:43 - 7:46everybody studied intelligence and how to measure it
-
7:46 - 7:48and was it possible to measure it very early in life and
-
7:48 - 7:51could we predict genius and so forth.
-
7:51 - 7:54And Katherine took a very
different take on her own research, -
7:54 - 7:58she wanted to know what
are these other qualities that -
7:58 - 8:01make for genius, that make for realized genius,
-
8:01 - 8:03people who are actually going to
do something in the world. -
8:03 - 8:07So she read the biographies of
300 well known geniuses -
8:07 - 8:10and she isolated a few qualities
which really distinguish -
8:10 - 8:13the geniuses who made a mark on the world.
-
8:13 - 8:16One of them was the tendency not to abandon task
-
8:16 - 8:18from mere changeability in her words.
-
8:18 - 8:22In other words not being a dilettante, not being a flake,
-
8:22 - 8:26not being me from the age of 22 to 32. Right?
-
8:26 - 8:30Sort of from one award to another, from one career
-
8:30 - 8:33to another, never actually setting sights on a port that
-
8:33 - 8:36I was going to consistently work towards, right?
-
8:36 - 8:39And I think we know many extremely bright people
-
8:39 - 8:43who don't have the capacity to stay on task,
-
8:43 - 8:47towards one goal and keep switching
from one to the other. -
8:47 - 8:50I teach at Penn, I see hundreds and thousands of
-
8:50 - 8:54kids pass through Penn's, you know, Ivy League portals
-
8:54 - 8:56and they have this conception
that essentially when they go off -
8:56 - 9:00into the world it will be an OK
and good strategy to go to -
9:00 - 9:04law school and if I don't like law, I filled my pre-med
-
9:04 - 9:06requirements so I could always
go back and do medical school and -
9:06 - 9:09if I don't like that there's always
management consulting; -
9:09 - 9:11the fall back of any Ivy League graduate, right.
-
9:11 - 9:15And what I want to tell them
is that history and psychology -
9:15 - 9:19tell us that changing around a lot is actually not
-
9:19 - 9:22a good way to get anywhere.
The other quality that she -
9:22 - 9:26isolated in her work, in her sort of reading of biographies
-
9:26 - 9:29was probably more predictable,
I think many teachers -
9:29 - 9:31and even many kids might recognize that
-
9:31 - 9:34having perseverance in the face of adversity,
-
9:34 - 9:37setbacks, failures, that is important.
-
9:37 - 9:39And that it's the combination
of those things that I call grit. -
9:39 - 9:43So it's this stamina quality not just being passionate
-
9:43 - 9:46but sustaining that passion for a long time.
-
9:46 - 9:48And these are items that
I give in a questionnaire -
9:48 - 9:51when I try to measure this quality in studies.
-
9:51 - 9:54Then the perseverance part as well, right.
-
9:54 - 9:56Setbacks don't disappoint me,
-
9:56 - 10:00I finish whatever I begin, I'm determined.
-
10:00 - 10:03I'm going to walk you through a couple of studies,
-
10:03 - 10:05and then I am going to speculate and it's only going to be
-
10:05 - 10:07a speculation about what we could possibly do for
-
10:07 - 10:10young people to cultivate this quality.
-
10:10 - 10:12The first study I want to tell you about was done
-
10:12 - 10:14at West Point Military Academy.
-
10:14 - 10:15The first summer when you go to
-
10:15 - 10:17West Point is called "Beast Barracks."
-
10:17 - 10:19So you show up, they check you for tattoos,
-
10:19 - 10:21can't have a tattoo if you go to West Point,
-
10:21 - 10:26they shave your hair,
they sit you down and you take -
10:26 - 10:30a very long battery of psychological intelligence tests.
-
10:30 - 10:36So I slipped in the grit scale, on this second day of
-
10:36 - 10:38training for a group of cadets.
-
10:38 - 10:44And like many other psychologist I had my battery of
-
10:44 - 10:46measures kind of hoping that I would be able
-
10:46 - 10:49to predict something over and beyond,
-
10:49 - 10:51what else is being collected at West Point.
-
10:51 - 10:53West Point has been collecting data for many years
-
10:53 - 10:56on what predicts survival through "Beast Barracks."
-
10:56 - 10:58So they lose a good number of their cadets every
-
10:58 - 11:01summer that they do this, the first year of cadets
-
11:01 - 11:04even though they try to select the sort of people that
-
11:04 - 11:06are obviously not going to drop out.
-
11:06 - 11:10So here are the results, grit is the dark blue line and
-
11:10 - 11:14essentially how to read this graph is
on the left is the percentage of -
11:14 - 11:17the cadets, who actually retained through the summer,
-
11:17 - 11:18the summer of "Beast Barracks."
-
11:18 - 11:22And on the X axis is what quartile you're in.
-
11:22 - 11:25So at the far right hand,
we have people in the top -
11:25 - 11:29quartile on grit scores --
96 percent of those cadets -
11:29 - 11:31actually stayed through the summer.
-
11:31 - 11:34And you can see, essentially, that there's this
-
11:34 - 11:37positive relationship -- more grit more likely to stay.
-
11:37 - 11:39Here is the whole candidate score, this is a weighted
-
11:39 - 11:45average of you SAT, your GPA,
how many push-ups you can do, literally. -
11:45 - 11:49You can see that, it's actually true
that if your in the bottom 25% -
11:49 - 11:52of their whole candidate score you are more likely to
-
11:52 - 11:56drop out, but isn't it interesting that the top 25% of
-
11:56 - 11:59people on this score, which West Point has spent many
-
11:59 - 12:01years and lots of your tax dollars trying to figure out,
-
12:01 - 12:04the best predictor of performance.
-
12:04 - 12:07You know, the people in the top 25% were actually just
-
12:07 - 12:11about as likely to drop out, and self-discipline which is
-
12:11 - 12:14being able to resist temptation, it's also an important
-
12:14 - 12:16quality, but not such an important quality
-
12:16 - 12:18when it comes to high achievement.
-
12:18 - 12:21Very good quality when it comes to staying on your diet
-
12:21 - 12:23and doing your homework, not such a good quality,
-
12:23 - 12:27in terms of predicting extremely
high challenge achievement. -
12:27 - 12:28That seem to be predictive as well,
-
12:28 - 12:32not quite as predictive when you run the statistics as grit.
-
12:32 - 12:34We replicated the study, every single year
-
12:34 - 12:37in the last five years at West Point Academy
-
12:37 - 12:41leading lots of military people to call me and
-
12:41 - 12:43ask me how to increase grit in their cadets,
-
12:43 - 12:47in their special forces officers or navy seals,
-
12:47 - 12:50or in their air-force cadets.
-
12:50 - 12:55But, the point here is that grit is predicting something,
-
12:55 - 12:58people who stay in that very challenging environment
-
12:58 - 13:01are not just the very talented ones, it's something else.
-
13:01 - 13:03In fact this study, and in every study that
-
13:03 - 13:06I've run since then, I was looking to see whether
-
13:06 - 13:09the gritty people were the ones
who were the talented ones. -
13:09 - 13:12Maybe when you really good
at something it makes you stay in. -
13:12 - 13:13In fact we find quite the opposite,
-
13:13 - 13:15at West Point and elsewhere we find that
-
13:15 - 13:19the gritty people on measures of talent have less.
-
13:19 - 13:23So it's by no means a guarantee of grit that
-
13:23 - 13:28you actually start of as one of the gifted.
-
13:28 - 13:31Here I am gonna run quickly through some other studies.
-
13:31 - 13:34This is a grit measured by looking at peoples resumes
-
13:34 - 13:37for consistency and follow through I would have gotten
-
13:37 - 13:39a terrible grit score for my resume,
-
13:39 - 13:41would have gotten grit for breath, low for grit.
-
13:41 - 13:44This is actually looking at grit in college resumes
-
13:44 - 13:49as a predictor of the teacher effectiveness in a teacher's
-
13:49 - 13:50under resourced communities.
-
13:50 - 13:52And we measured teacher effectiveness the way
-
13:52 - 13:54it should be measured, which is the academic progress
-
13:54 - 13:57of their kids. And no other thing, I think,
-
13:57 - 13:59would substitute for that.
-
13:59 - 14:03We did a great study, and I mean it was just fun,
-
14:03 - 14:05of the National Spelling Bee kids.
-
14:05 - 14:08I called up the director of the National Spelling Bee,
-
14:08 - 14:10who herself was a National Spelling Bee champion,
-
14:10 - 14:13she corrected the spelling on my email on her return,
-
14:13 - 14:14and that was fine too.
-
14:14 - 14:18And these kids are extraordinary children, and I think
-
14:18 - 14:21many people have this stereotype that Spelling Bee kids
-
14:21 - 14:24are verbal geniuses and the ones who win
-
14:24 - 14:27the Spelling Bee are sort of more genius-like
-
14:27 - 14:29than the ones who don't win the Spelling Bee.
-
14:29 - 14:31So I asked the director if that were true and she said,
-
14:31 - 14:34"I don't think so but I don't know what it is."
-
14:34 - 14:39So we surveyed kids before they actually went to the Bee
-
14:39 - 14:43and what we found is that,
again grit is the dark blue line, -
14:43 - 14:46so the kids who actually placed higher in the finals
-
14:46 - 14:51of the National Spelling Bee
were higher in grit and -
14:51 - 14:54here is they verbal IQ, verbal IQ did predict,
-
14:54 - 14:56but again, the kids who were really high in verbal IQ
-
14:56 - 14:58tended to be lower in grit.
-
14:58 - 15:02So they were not merit, they were inversely related
-
15:02 - 15:06and self-discipline here,
being able to resist temptation, -
15:06 - 15:08stay on a diet, do you homework when you need to --
-
15:08 - 15:11Interestingly, the kids who were very high in
-
15:11 - 15:13self-discipline did do better.
-
15:13 - 15:15But there was also the slacker group,
-
15:15 - 15:18in a bottom 25% of self-discipline who also did quite well
-
15:18 - 15:21but just about as well as the top.
-
15:21 - 15:23So again self-discipline, great for doing homework,
-
15:23 - 15:26terrific predictor of GPA, not such a great predictor
-
15:26 - 15:31of are you gonna find a blue man
group and stay with it, etc. -
15:31 - 15:34In a follow-up study to this one we investigated why
-
15:34 - 15:37is it that gritty kids are wining the Spelling Bee.
-
15:37 - 15:39So we recruited another sample of kids from
-
15:39 - 15:42the following year Spelling Bee, we sent them surveys,
-
15:42 - 15:45we measured they grit on self-report questionnaires,
-
15:45 - 15:47but then we asked them very detailed question about
-
15:47 - 15:50what they did. So it turns out the kids who were in
-
15:50 - 15:52the National Spelling Bee competition,
-
15:52 - 15:56they're studying anywhere from an hour a week to
-
15:56 - 16:01scarily 35 or 40 hours a week but what differentiate kids
-
16:01 - 16:04who are gritty from kids how are not gritty
-
16:04 - 16:06it's not just the hours of work that they are putting in
-
16:06 - 16:09they're putting the hardest kind of work in.
-
16:09 - 16:12They are not studying the words they are already know,
-
16:12 - 16:14they're not sitting around being quizzed on
-
16:14 - 16:16what's pretty much coming easily,
-
16:16 - 16:19they isolate what they don't know, they identify their own
-
16:19 - 16:22weaknesses and then they work just on that.
-
16:22 - 16:25And that seems to characteristic of high achievement
-
16:25 - 16:27and what grit enables you to do.
-
16:27 - 16:29It's basically, being in a very uncomfortable place
-
16:29 - 16:33for some part of your day
working extremely hard and then -
16:33 - 16:37to get up and do it all over again and again and again.
-
16:37 - 16:40There is a graph that goes with this 10-year-old,
-
16:40 - 16:42that I mentioned at the beginning of the talk,
-
16:42 - 16:44this is the deliberate practice graph, this graph actually
-
16:44 - 16:49accurately describes the rise of skill, the gain in skill
-
16:49 - 16:52over time for really just about any
domain that's been studied. -
16:52 - 16:57Even Mozart, who some would argue
is proof of concept for genius -- -
16:57 - 17:00Mozart must have been born as great as he was
-
17:00 - 17:02because who else could have been composing
-
17:02 - 17:06melodies that we're still listening to, at the age of 5 or 6.
-
17:06 - 17:09It turns out that Mozart also fits this graph but he was
-
17:09 - 17:13doing probably 8 hours of deliberate practice a day,
-
17:13 - 17:15from as early as he could sit up,
-
17:15 - 17:18whereas most of class performers only do 4.
-
17:18 - 17:20But Mozart at very early age had already accumulated
-
17:20 - 17:24basically 10,000 hours of deliberate practice.
-
17:24 - 17:27Here is the interesting thing on the graph,
-
17:27 - 17:30so it's really 10 years since you started discipline
-
17:30 - 17:33till you get to world class peak performers.
-
17:33 - 17:35And another interesting point about this which
-
17:35 - 17:37you can't see from this graph is that
-
17:37 - 17:41most people do this, they don't have the grit to
-
17:41 - 17:44essentially sustain this deliberate practice over all
-
17:44 - 17:48this time and they basically plato here.
-
17:48 - 17:50I want to end with a couple of quotes.
-
17:50 - 17:54If you look at early films of people that we all love --
-
17:54 - 17:56maybe you love Will Smith -- I do --
-
17:56 - 18:00maybe you love Matt Dillon or Rob Lowe,
-
18:00 - 18:03take any Academy Award winning actor and
-
18:03 - 18:05go watch one of their first films.
-
18:05 - 18:09More likely than not it was terrible.
-
18:09 - 18:10So the interesting thing is what makes somebody
-
18:10 - 18:13have a terrible film, which is poorly reviewed,
-
18:13 - 18:15and actually stay with it?
-
18:15 - 18:17Whatever it is, I think Will Smith has got it,
-
18:17 - 18:20and he was also very funny when he talks about it.
-
18:20 - 18:22And I think Woody Allen has it.
-
18:22 - 18:27And I think that essentially the question
for the Blue [unclear] School -
18:27 - 18:29and for the rest of us who are interested in children is
-
18:29 - 18:32whatever that is, let's figure it out and then
-
18:32 - 18:35through the art which is teaching and education
-
18:35 - 18:36let's bring it to children.
-
18:36 - 18:38Thank you very much.
