- [Radio] I want you to go to 180
- GFA 737, going to 180 speed.
I am not a pilot.
So what am I doing
trying to land a 737 passenger jet?
Okay, this is weird. (alarm sounding)
- [Radio] (indistinct).
- Oh, okay. (chuckles)
Well, I'm trying to prove a point.
Let's keep the hands on the controls there, buddy.
How big is the difference
between what we think we know
and what we actually know?
Uh-oh we're gonna miss the runway! (laughs)
Well, we're about to find out.
Oh God, we're in the air again.
This is not good.
(tense violin music)
Hey, smart people, Joe here.
Let me know if this thought has ever crossed your mind,
when you're sittin there on an airplane.
Okay, what if the flight attendant
suddenly got in the intercom and they're like,
"Does anybody know how to land this plane?"
What would you do?
Well, I think about this all the time.
And I think that I would actually raise my hand,
and say, "Yes."
Because there's a certain kind of YouTube video
that I love,
it's pilots landing planes,
all those shots from inside the cockpit,
I love this stuff.
I cannot get enough of it.
And you know what?
It makes me feel like,
I could actually do this,
I've watched enough of it.
So today we're gonna put that to the test
by going to an actual flight simulator,
and
see if I really know what I'm doing.
Hey, so Future Joe here,
that was me a couple weeks ago.
Probably a little more confident
than I should have been.
I know I'm not the only one
who's ever sat in their seat on a flight,
and wondered this exact thing, right?
And especially, if like me,
you played a lot of flight simulator games
when you were younger,
and you love YouTube videos of pilots flying planes-
- We're coming up.
You can start watching your (indistinct),
- [Radio] Okay 187,
lowering at 5,000, crossing.
- Seriously,
they're just so calming to watch,
it's like how I meditate.
But I am not a pilot.
And I think most of you watching this video,
especially if you are a pilot
are probably wondering,
how could this guy possibly think
he can actually land a passenger jet?
Well, I did this because I wanted to understand
how we judge what we think we know,
or what we think we're good at,
versus what we actually know.
So recently,
some psychologists actually investigated this very question.
When people watched a video
of a pilot landing a plane,
they were more likely to say they themselves
could land a plane without dying,
even though none of them
had any actual flying experience,
which is just nuts, obviously.
I mean, flying a plane takes a ton of skill and practice.
This is just one example
from a huge body of research
about a famous psychological phenomenon
called the "Dunning-Kruger Effect".
- The "Dunning-Kruger Effect"
is actually an entire family of effects,
but the one that everybody knows
is that people who aren't knowledgeable,
aren't expert,
don't know the depths of their lack of knowledge.
If you're making wrong decisions,
you don't know you're making wrong decisions.
My name is David Dunning,
I'm a Professor of Psychology at the University of Michigan.
- In 1999,
he and Justin Kruger published this paper.
They found that people
who are incompetent at something
overestimate their abilities more than anyone else,
and the "Dunning-Kruger Effect" was born.
It's gotta be pretty weird
to have something named after you
that's all about how people make mistakes
or how ignorant they are.
- We didn't name it,
the internet named it.
And I think our attitude is,
we are impressed with the fact
that our name is...
Our good family name is gonna be forever associated
with ignorance, incompetence,
nincompoop-ery.
- Now, based on the countless hours that I've spent
landing planes in Microsoft flight simulator
or watching cockpit YouTube videos,
I certainly wouldn't claim
to know as much as an actual pilot.
I mean, flying a huge jet
is an incredibly specialized skill,
but I feel pretty confident
that I know a lot more than the average person,
but is that enough for me
to bring a plane safely down to the ground
with an expert pilot guiding me over the radio?
Well, that is what we're about to put to the test.
Hans.
- Hey Joe, nice to meet you.
- I guess I'm gonna try to land a plane, today.
Fingers crossed, that's all I gotta say. (laughs)
Hans is a pilot with thousands of hours
of flying experience,
for a major airline.
Now, if this were to happen in the real world,
air traffic control would immediately bring in a pilot
like Hans,
who knows that particular aircraft
to direct a passenger what to do.
I'll be sitting in this simulator,
a 100% accurate replica
of a Boeing 737NG airliner cockpit.
Hans will only be able to communicate with me
via radio,
and he'll only be able to see
what air traffic control would see,
my altitude, where I'm heading, and how fast.
He won't be able to see any of the flight controls,
or what the plane's doing,
so this is really up to me.
- So today we're gonna assimilate a flight
from Chicago to Boston,
in a 737 800NG.
It's a very common airplane,
it has fully automated capability landing
on the runway.
The younger generation,
they're very familiar with the video games,
and so forth.
You should be able to punch the buttons
and program the airplane
so it completely brings you down
all the way down to the runway.
- And then, maybe we'll give me a shot
at trying to do it.
- Yeah, absolutely though,
because with the automation,
and I can follow you on the radar screens
to see where the airplane is going,
and then we'll just have to talk you,
try to make you land the airplane by yourself.
- Wow, okay,
there's so much in front of me, here. (chuckles)
Hello, I'm a passenger
on a flight to Boston, without pilots.
I need help.
- That's not a good situation.
- [Joe] So there have been cases where a passenger
successfully landed a small plane,
after a pilot became incapacitated,
but a passenger would likely never have to
actually fly a modern airline jet.
Not only do modern airliners have more than one pilot
in the cockpit for this very reason,
today's aircraft are highly automated
and many can fly and even land themselves,
if programmed correctly.
If this scenario happened in the real world,
this is what someone from air traffic control
would direct a passenger to do.
- Now comes the hard part.
All right Joe,
we're gonna program the keypad
on your right knee
- The screen near my knee
controls the flight management computer,
Hans is guiding me through a series of steps
to give the plane the right information
to land itself.
By entering a series of GPS points along our route,
and information about the airport and runway
where we wanna land,
this computer can control the autopilot
all the way down to the ground.
If I do all the steps correctly.
and remember to put the flaps and gear down,
the plane should basically land itself.
There's so much happening.
And I don't even feel like I'm actually flying,
I'm just like reading...
The flying part,
I don't even know how I'm gonna fit that in.
As we approach the runway,
the list of things I need to do, seems endless.
- The speed rate and move it one inch towards you.
- I've seen those when you fly,
they come up on the wing.
That's cool.
Even though things are generally on auto,
it's not easy.
This is the heck of a turn.
Whew!
Approaching the intercept.
That sounded right, I don't know.
I've heard people say stuff like that.
- I'm gonna let you put the gear on.
- That's good.
Gear's good.
- [Hans] You should be able to see Boston.
- Do you see the runway yet?
Even though I can barely see the runway,
the plane knows where to go.
I can't believe that this can just land itself,
this is crazy.
- [Cockpit Speaker] Approaching minimums.
100.
- We're gonna (indistinct) here
in like, 50.
- [Cockpit Speaker] 50, 40, 30,
20, 10. (Joe chuckles)
(suspenseful music)
(Joe exhales)
- Cut off.
(alarm sounding)
That was so much,
I can't imagine actually flying.
(Joe exhales)
My brain is exhausted
from having to do so many things.
And I don't feel like I really
actually even flew the plane,
it was just punching buttons and turning things.
And I'm already overloaded,
that actually having to fly the plane,
I don't know how I'm gonna have time to do it.
There's so many other things you have to do,
like flying the plane?
That's too much.
So we're gonna try this again,
and this time I'm actually gonna have to fly.
This is not gonna go well.
Okay, so I successfully got the plane on the ground.
I feel pretty good,
what could go wrong?
I think I have manual control of the airplane
- [Hans] Slowly push the yoke a little bit forward,
so the flight director
goes slightly below the horizon.
- This is so hard.
I'm having trouble keeping the plane
at an altitude.
I'm getting very low, actually,
I need to pull up to 3000.
I can barely make out the runway, at this point.
- [Hans] Okay, that will be the runway
you will be landing on, Joe,
so we're all counting on you.
- (chuckles) Okay.
I can't keep this thing on a course at all.
A little bit more, a little bit more.
I don't feel like I'm line for the runway, here.
- You wanna have the red over the white lights.
- Yeah, definitely coming in low.
- [Hans] We're gonna turn off the auto throttle.
- Okay, I have control of the throttle.
- [Cockpit Speaker] 300. - Okay.
Oh boy.
Pull up.
- [Cockpit Speaker] Approaching minimums.
100.
- Uh-oh, (laughing)
this is the runway!
I'm gonna hit these lights.
Okay, we're coming in over the end of the runway.
Trying to power back
- [Cockpit Speaker] 20, 10.
- Oh no!
(Joe exclaiming)
I'm like shaking. (chuckling)
I don't think that really would've worked.
Yeah, so, I was able to bring the plane down to the runway,
but-
- [Hans] Oh well, but you crushed the gear.
- I crushed the gear? - [Hans] Oh yeah.
(both laughing)
- In real life this means
the plane would've slid down the runway
likely starting a major fire.
So technically, I crashed.
Luckily I'm gonna get one more chance,
only without the autopilot helping me at all.
So it turns out flying
is harder than I thought,
than just watching a few YouTube videos.
When you actually have to fly the plane
and put it on the ground,
I didn't do it, is what I'm saying, I crashed.
Having a little bit of knowledge
and seeing what pilots do in the cockpit
from watching all these videos,
it was this weird feeling of knowing
I should be doing something,
but not knowing what I didn't know how to do.
And then all of a sudden
there's the runway, and it's too late,
and you break the landing of gear off, and everyone's dead.
It didn't go well, that's what I'm saying.
So in some cases,
having a little bit of experience may
actually lead to more Dunning-Kruger
over confidence, than having no experience at all.
According to data,
pilots with a couple hundred hours of flying experience
they tend to have the most fatal accidents,
not pilots who are just starting out.
It's known in aviation as "The Killing Zone".
I feel like I've been there.
- If you asked me,
"Okay, who's the most vulnerable
to the "Dunning-Kruger Effect"?
I would say is that everybody is vulnerable
to the "Dunning-Kruger Effect".
And sooner or later
you will have your time,
in the "Dunning-Kruger Effect".
Though it's likely the case, you won't know.
I think hitting the limit of your own knowledge
is a day to day experience.
- What Dunning and lots of other scientists have found,
is we are not always very good
at judging our knowledge.
And we overestimate what we know, a lot.
There's countless studies
and the "Dunning-Kruger Effect"
shows up just about everywhere we look.
In one famous example,
when given a quiz
more than 90% of people claim to be familiar
with completely made up concepts
when presented alongside real ones.
There are many reasons people may claim
to know more than they really do.
I mean, we want to fit in socially
or that we unconsciously tend to view ourselves
as above average,
in everything from intelligence to sense of humor.
In one study,
93% of Americans said they were safer
and more skillful behind the wheel
than the median driver,
which is mathematically impossible.
But the "Dunning-Kruger Effect" is a special kind
of overconfidence,
because it's rooted in a paradox.
You aren't able to know what you don't know,
so when you mess up, you might not be able to realize it.
- The knowledge you need
to come to the right decision,
is exactly the same knowledge that you need
to decide whether the right decision has been made.
And if you lack the first,
you lack the knowledge you need
for the second assessment.
In fact, the French novelist Anatole France
once said a true education is not learning things,
but learning to separate what you know
from what you don't know.
- Now, we're gonna up the ante a little bit,
a nice cloudy day coming down into the runway.
It's down there somewhere.
This is not gonna go well.
Auto throttle and autopilot are disengaged.
Oh God, oh boy.
If I breathe wrong, I'm off course here.
Okay, I'm getting low.
(Joe singing to himself)
Just trying to stay right in here.
Let's keep your hands on the controls there, buddy.
- [Cockpit Speaker] Glide slope.
- I hear ya.
Glide slope
- [Cockpit Speaker] Glide slope.
- Ah! Ah!
Ah! - [Cockpit Speaker] 30, 20,
(Joe yelling)
- Oh God, we're in the air again.
This is not good.
Wait, am I alive?
The simulator doesn't show it,
but that was a crash, too.
My score when actually flying,
is 0 for 2.
That was not great.
I apologize to the 150 or so people
who paid for tickets on this flight.
So that didn't go very well,
the last time I crashed.
That was just so much harder
than I figured it would be,
even understanding how a plane should be flown.
And then I could tell there was just things
that I didn't know how to do.
- So that's what we call in aviation, Joe,
the chain of events.
We're increasing the severity level, slowly,
making sure that you manually doing the throttle,
and the yoke,
and averting attention to all the controls,
put you in what we call an overload situation.
- What we find with the "Dunning-Kruger Effect"
is that people are unable to know
what they don't know
and that's needs to be one of the differences
between what experts are
versus what normal people.
What does it mean to be an expert pilot?
- To be an expert pilot
is that we have had the training,
so we know what to anticipate,
what's gonna happen.
- I knew that there was a problem,
but I didn't know what to do to correct the problem.
- As a novice, you just don't know what to expect.
So every situation,
every second is something that you have no clue
what the outcome is.
- And of course, being able to fly
is an important prerequisite
to getting to be a pilot, also,
which I obviously don't know how to do.
- But- - Just a little bit.
- You have prospect,
there's room for improvement.
- All right, so if you're saying
if this whole YouTube thing doesn't work out.
(Hans laughing)
- There's a place for you at the airlines.
(both chuckling)
- What I've learned and what's really the key here,
is the "Dunning-Kruger Effect" is not just
stupid people think they're smarter
than they really are.
What it really says
is that every one of us is ignorant
about many things,
economic theory, car repair,
football strategy.
That lack of knowledge means we won't even know
when we're making mistakes.
You don't know the things you don't know,
so when you mess up, you won't even realize it.
And it's not just something that happens to other people,
we're all at risk of this in our daily lives.
You're probably thinking what I'm thinking
by this point,
"But the internet."
Has all of this made the "Dunning-Kruger Effect"
worse today?
Well, this failure of self knowledge
has probably always been with us,
it's just part of the human condition.
But the internet has made it more visible today
for two reasons,
we just interact with more stuff.
So you're gonna run into more things
you don't know very much about.
And the internet is designed
to beg you to talk about it.
The second reason, the internet makes it easier
to learn a tiny bit about something
and enter that very dangerous Dunning-Kruger
overconfidence zone,
where you know just a little bit more than nothing.
So how do you avoid it?
- One thing to do is to depend on other people,
that they're gonna be perfectly knowledgeable, as well,
but two heads are absolutely better than one.
Three are slightly better than two,
so what a decision is an important one,
you do want to check your math,
you do want to check your reasoning
with another person.
If we try to go it along,
that's when we get into trouble.
- This is why pilots rely
on those huge checklists and manuals.
So they don't rely just on their own knowledge
in order to not make mistakes.
And this is why science works,
science outsources that whole process
of checking for errors, to lots of other brains.
That's what peer review means.
Science doesn't go out and confirm ideas,
it tries to disprove them,
and whatever survives
is a little bit closer to the truth.
Confidence has benefits,
it can be the boost that we need
to help us take on life's challenges.
But overconfidence
can definitely also be a bad thing.
What we know is finite,
what we don't know is infinite,
and that border between what we know
and what we don't know,
we meet it more often than we think ,
even in everyday life.
And that's actually something
we should all get more comfortable with
because if we knew everything,
life would be boring.
Not knowing things gives us a chance to learn,
to be a different person,
a better person, tomorrow, than we are today.
Knowing how much we don't know
gives life a purpose.
Stay curious,
and please secure your tray tables
to their upright and locked position,
we're approaching the end of this video.
Wait,
land a plane with no experience?
Surely you can't be serious!
I am serious,
and don't call me surely,
and surely we can't end this video
without thanking everyone who supports the show
on Patreon,
you guys help make videos like this one possible.
If you'd like to see more of me
trying to land that plane or not,
we have an uncut version.
It's up on the Patreon page now,
it's pretty funny,
I think you're gonna like it.
And you can find out more
about how you can support the show,
help us make more videos like this one,
and a whole lot of others that we've got planned.
Just click the link down in the description
and we'll see you in the next video,
safely on the ground,
not trying to fly a plane.
What was I even thinking?
Why did I think I could do that?
That was bonkers.
Well, you'll be happy to know
that if this ever did happen in real life,
it turns out there's a little computer in the cockpit
that if you punch in all the right numbers
and radio frequencies,
the plane will completely land itself
and come to a complete stop.
- Interesting, don't tell Elon Musk.
