S… Speaker 2 (all)
You're standing at the edge of a tall building.
0:02
S… Speaker 1 (all)
There's a railing in front of you.
0:04
S… Speaker 1 (all)
You are completely safe.
0:06
S… Speaker 1 (all)
But your body doesn't believe it.
0:09
S… Speaker 1 (all)
Your palms go damp.
0:11
S… Speaker 1 (all)
Your knees feel loose.
0:13
S… Speaker 1 (all)
Something in your stomach drops.
0:16
S… Speaker 1 (all)
You think you're afraid of heights.
0:18
S… Speaker 1 (all)
But the truth is far stranger than that.
0:21
S… Speaker 1 (all)
You're not afraid of the height itself.
0:24
S… Speaker 1 (all)
You're afraid of a fall that hasn't happened,
0:27
S… Speaker 2 (all)
and statistically,
0:28
S… Speaker 2 (all)
never will.
0:30
S… Speaker 2 (all)
Think about it for a moment.
0:31
S… Speaker 1 (all)
Most people who fear heights have never actually fallen from
0:35
S… Speaker 1 (all)
one. You've never plunged from a cliff.
0:38
S… Speaker 1 (all)
You've never dropped from a tower.
0:41
S… Speaker 2 (all)
So where does this terror come from,
0:43
S… Speaker 2 (all)
if not from experience?
0:44
S… Speaker 1 (all)
The answer was hiding in a laboratory in 1960.
0:48
S… Speaker 1 (all)
A psychologist named Eleanor Gibson built something strange.
0:52
S… Speaker 1 (all)
She called it the visual cliff.
0:56
S… Speaker 2 (all)
It was a glass table,
0:57
S… Speaker 2 (all)
and beneath the glass,
0:58
S… Speaker 2 (all)
a checkered floor that suddenly dropped away into a deep gap.
1:02
S… Speaker 1 (all)
To the eye,
1:03
S… Speaker 2 (all)
it looked like the edge of a cliff.
1:05
S… Speaker 1 (all)
But the glass made it perfectly safe to crawl across.
1:09
S… Speaker 1 (all)
Then she placed babies on it.
1:12
S… Speaker 1 (all)
Babies who had never fallen.
1:14
S… Speaker 1 (all)
Babies who had never been hurt by a height in their lives.
1:18
S… Speaker 2 (all)
And almost every single one of them stopped at the edge.
1:21
S… Speaker 2 (all)
They refused to crawl over the drop,
1:24
S… Speaker 2 (all)
even when their own mothers called to them from the other side.
1:27
S… Speaker 1 (all)
Then she tried it with animals.
1:29
S… Speaker 1 (all)
Kittens.
1:30
S… Speaker 1 (all)
Baby chicks.
1:32
S… Speaker 1 (all)
Newborn goats.
1:34
S… Speaker 1 (all)
Every one of them froze at the edge of the visual cliff.
1:38
S… Speaker 1 (all)
None of them had to learn that falling was dangerous.
1:41
S… Speaker 1 (all)
They already knew.
1:43
S… Speaker 1 (all)
This is the part that should unsettle you.
1:46
S… Speaker 1 (all)
The fear of heights isn't taught to you.
1:50
S… Speaker 2 (all)
It's installed in you.
1:51
S… Speaker 1 (all)
You were born carrying a piece of ancient software,
1:55
S… Speaker 2 (all)
written long before you existed.
1:57
S… Speaker 1 (all)
But here's a detail most people miss.
1:59
S… Speaker 1 (all)
That fear isn't switched on at birth.
2:03
S… Speaker 2 (all)
The psychologist Joseph Campos discovered something remarkable.
2:06
S… Speaker 1 (all)
Babies only begin to fear the visual cliff around the time
2:10
S… Speaker 2 (all)
they learn to crawl.
2:11
S… Speaker 1 (all)
It's as if the body waits.
2:14
S… Speaker 1 (all)
It holds the fear in reserve,
2:16
S… Speaker 2 (all)
then activates it at the exact moment you become able to move toward danger.
2:21
S… Speaker 2 (all)
The instinct doesn't arrive a day too early.
2:23
S… Speaker 1 (all)
It arrives precisely when you need it.
2:26
S… Speaker 1 (all)
Your body has been keeping you alive on a schedule you never agreed
2:30
S… Speaker 1 (all)
to. To understand who wrote that schedule,
2:33
S… Speaker 2 (all)
you have to go back.
2:35
S… Speaker 2 (all)
Far back,
2:36
S… Speaker 2 (all)
to a time when your ancestors lived in the trees.
2:39
S… Speaker 2 (all)
For tens of millions of years,
2:41
S… Speaker 2 (all)
primates like us made their homes high in the canopy.
2:44
S… Speaker 1 (all)
Up there,
2:45
S… Speaker 2 (all)
food was plentiful and predators were fewer.
2:48
S… Speaker 1 (all)
But there was one rule that never bent.
2:51
S… Speaker 2 (all)
If you fall,
2:52
S… Speaker 2 (all)
you die.
2:53
S… Speaker 1 (all)
There were no hospitals.
2:55
S… Speaker 1 (all)
No safety nets.
2:57
S… Speaker 1 (all)
No second chances.
2:59
S… Speaker 1 (all)
A single misjudged branch meant the end of your story and
3:04
S… Speaker 2 (all)
the end of your bloodline.
3:05
S… Speaker 1 (all)
And so evolution did what evolution always does.
3:08
S… Speaker 1 (all)
It kept the careful ones.
3:11
S… Speaker 1 (all)
The ancestors who felt that lurch of fear near an edge pulled
3:15
S… Speaker 2 (all)
back and survived and had children.
3:18
S… Speaker 2 (all)
The ones who felt nothing stepped confidently into open air,
3:21
S… Speaker 2 (all)
and vanished from history.
3:23
S… Speaker 1 (all)
Every human being alive today is descended from the ones who
3:27
S… Speaker 2 (all)
were afraid.
3:28
S… Speaker 1 (all)
The neuroscientist Joseph Ledoux spent his career mapping
3:32
S… Speaker 2 (all)
this circuit.
3:32
S… Speaker 1 (all)
He found that fear doesn't begin in the thinking part of your brain.
3:36
S… Speaker 1 (all)
It begins deeper,
3:38
S… Speaker 2 (all)
in a small almond -shaped structure called the amygdala.
3:42
S… Speaker 2 (all)
This region reacts to danger before your conscious mind even knows what
3:46
S… Speaker 2 (all)
is happening.
3:46
S… Speaker 2 (all)
That's why the fear feels so fast.
3:49
S… Speaker 1 (all)
By the time you think you're safe because there's a railing,
3:52
S… Speaker 2 (all)
your body has already responded.
3:54
S… Speaker 1 (all)
Your heart is already pounding.
3:57
S… Speaker 1 (all)
Your legs have already gone weak.
3:59
S… Speaker 1 (all)
The ancient part of you doesn't trust the railing.
4:03
S… Speaker 1 (all)
It has never heard of railings.
4:05
S… Speaker 1 (all)
But here's where it gets even stranger.
4:08
S… Speaker 1 (all)
Your fear of heights isn't only about falling.
4:12
S… Speaker 2 (all)
It's also about how your body quietly reads the world to stay upright.
4:16
S… Speaker 1 (all)
Researchers found that people who fear heights rely more heavily
4:20
S… Speaker 2 (all)
on their eyes to keep their balance.
4:21
S… Speaker 2 (all)
When you stand on solid ground,
4:23
S… Speaker 2 (all)
you balance using three systems at once.
4:26
S… Speaker 1 (all)
Your inner ear.
4:28
S… Speaker 1 (all)
The sensors buried in your muscles.
4:31
S… Speaker 1 (all)
And your vision.
4:32
S… Speaker 1 (all)
But up high,
4:34
S… Speaker 2 (all)
your eyes lose their anchor.
4:36
S… Speaker 2 (all)
The ground is too far to read,
4:38
S… Speaker 2 (all)
the horizon seems to tilt,
4:40
S… Speaker 2 (all)
and suddenly your brain has nothing stable to hold on to.
4:43
S… Speaker 1 (all)
So it panics.
4:45
S… Speaker 1 (all)
It feels as if you are swaying,
4:48
S… Speaker 2 (all)
even when you are standing perfectly still.
4:50
S… Speaker 1 (all)
This is why looking down makes everything worse.
4:53
S… Speaker 1 (all)
You're feeding your brain the exact information it cannot process.
4:57
S… Speaker 1 (all)
Your fear isn't irrational.
5:00
S… Speaker 1 (all)
It's your balance system screaming that it has lost its map.
5:04
S… Speaker 2 (all)
And then there is the strangest part of all.
5:07
S… Speaker 2 (all)
Have you ever stood somewhere high and felt a sudden,
5:10
S… Speaker 2 (all)
bizarre urge to jump?
5:11
S… Speaker 1 (all)
Not because you are sad.
5:13
S… Speaker 1 (all)
Not because any part of you wants to.
5:16
S… Speaker 1 (all)
Just a flickering thought that comes from nowhere and frightens you deeply.
5:20
S… Speaker 1 (all)
You are not alone,
5:22
S… Speaker 2 (all)
and you are not broken.
5:24
S… Speaker 1 (all)
In 2011,
5:26
S… Speaker 2 (all)
a researcher named Jennifer Haim studied this exact sensation.
5:29
S… Speaker 1 (all)
She called it the high place phenomenon.
5:32
S… Speaker 1 (all)
And what she found was almost the opposite of what people fear
5:36
S… Speaker 1 (all)
about it.
5:38
S… Speaker 2 (all)
That urge is not a hidden death wish.
5:40
S… Speaker 1 (all)
It is a survival signal misfiring.
5:43
S… Speaker 2 (all)
Your brain fires a lightning -fast alarm,
5:45
S… Speaker 2 (all)
step back,
5:46
S… Speaker 2 (all)
danger,
5:47
S… Speaker 2 (all)
and it arrives so quickly that your slower conscious mind misreads the message.
5:51
S… Speaker 1 (all)
The pull you feel isn't really toward the edge.
5:54
S… Speaker 1 (all)
It is the echo of a warning that screamed at you to retreat.
5:58
S… Speaker 1 (all)
Now look at what we have built on top of this ancient alarm.
6:02
S… Speaker 1 (all)
We raise glass towers a thousand feet into the sky.
6:06
S… Speaker 2 (all)
In China,
6:07
S… Speaker 2 (all)
millions of people travel to walk across glass -bottomed bridges suspended over
6:11
S… Speaker 2 (all)
deep canyons.
6:12
S… Speaker 1 (all)
We have turned a survival instinct into entertainment,
6:16
S… Speaker 2 (all)
and we pay money to feel it.
6:17
S… Speaker 1 (all)
A mild fear of heights is almost universal.
6:21
S… Speaker 1 (all)
It lives,
6:22
S… Speaker 2 (all)
to some degree,
6:23
S… Speaker 2 (all)
in nearly all of us.
6:25
S… Speaker 1 (all)
For about 1 in 20 people,
6:27
S… Speaker 2 (all)
it grows into something sharper,
6:29
S… Speaker 2 (all)
something that can shrink the size of a life.
6:32
S… Speaker 2 (all)
But even in its gentlest form,
6:34
S… Speaker 2 (all)
it is doing the same quiet job it has always done.
6:37
S… Speaker 2 (all)
It is the voice of every ancestor who ever clung to a branch and lived.
6:41
S… Speaker 1 (all)
So think about what is really happening when you freeze at a height.
6:45
S… Speaker 1 (all)
You are not weak.
6:47
S… Speaker 1 (all)
You are not foolish.
6:49
S… Speaker 1 (all)
You are feeling the accumulated wisdom of a hundred million years
6:53
S… Speaker 2 (all)
of survival,
6:54
S… Speaker 2 (all)
compressed into a single cold second.
6:56
S… Speaker 1 (all)
Your body is running a calculation older than language,
7:00
S… Speaker 2 (all)
older than fire,
7:01
S… Speaker 2 (all)
older than the human face.
7:03
S… Speaker 2 (all)
The next time you stand somewhere high and feel yourself go cold,
7:07
S… Speaker 2 (all)
notice what your body is doing.
7:08
S… Speaker 1 (all)
It is not failing you.
7:11
S… Speaker 1 (all)
It is protecting you,
7:13
S… Speaker 2 (all)
in the only way it has ever known.
7:15
S… Speaker 2 (all)
That railing might be made of steel.
7:17
S… Speaker 1 (all)
But the fear holding you back is older than steel,
7:20
S… Speaker 2 (all)
older than cities,
7:21
S… Speaker 2 (all)
older than humankind itself.
7:23
S… Speaker 1 (all)
You were never truly afraid of the height.
7:26
S… Speaker 1 (all)
You were always afraid of the fall,
7:29
S… Speaker 2 (all)
and that fear is the reason you are alive to feel it.
