You're not living in this very moment that you're experiencing, and nothing is like it seems.

你並沒有活在你正在經歷的這一刻，一切都不像看上去那樣。

It turns out your brain constructs your reality as you're experiencing it.

原來，你的大腦會在你體驗現實的過程中構建你的現實。

It edits your memories as they happen.

它能在記憶發生時對其進行編輯。

It lives in totally different time spheres and tells you a story about the world that feels real.

它生活在完全不同的時空裡，為你講述一個真實的世界故事。

What's going on, and who's really in control of your life?

到底發生了什麼，誰在真正掌控你的生活？

The gap between reality and you.

現實與你之間的差距

Vision is maybe our main source of information about the world, but in reality we don't really see that much.

視覺也許是我們瞭解世界的主要資訊來源，但實際上我們看到的並不多。

Only a thumbnail-sized area of your visual field is in high resolution, while the rest is out of focus.

你的視野中只有一個縮略圖大小的區域是高分辨率的，其他區域都是失焦的。

If it doesn't feel like this, that's because it's made up by your brain, using a pretty neat trick.

如果感覺不是這樣，那是因為這是你的大腦用一種非常巧妙的技巧編造出來的。

Each second, your eyes make three to four sudden jerky movements, saccades of 50 milliseconds, focusing from one point to another, scanning your environment to get different sharp images that your brain then edits together.

每秒鐘，你的眼睛會突然做出三到四次生澀的動作，即50毫秒的眼球移動，從一個點聚焦到另一個點，掃描你所處的環境，以獲得不同的清晰影像，然後由大腦將這些圖像編輯在一起。

During a saccade, your brain shuts down your vision so you don't see a wild motion blur.

在囊狀移動過程中，大腦會關閉視覺，這樣你就不會看到瘋狂的運動模糊。

This means that each day, for around two hours, you're completely blind.

這意味著，每天大約有兩個小時，你是完全失明的。

If you could actually see what your eyes see, it would look something like this.

如果你真的能看到你眼睛所看到的東西，它看起來會是這樣的。

Instead, your brain fills this time with its best guesses of what happened during the blackness.

相反，你的大腦會用它對黑暗中發生的事情的最佳猜測來填補這段時間。

But it does way more.

但它的作用遠不止於此。

It turns out that you're not really experiencing time correctly.

原來，你並沒有真正正確地體驗時間。

What's really happening when you're stirring milk into a cup of coffee?

在一杯咖啡中攪拌牛奶時到底發生了什麼？

As the spoon hits the ceramic, light reflects off it and hits your eyes after 1.3 nanoseconds.

當勺子碰到陶瓷時，光線會反射到陶瓷上，並在 1.3 納秒後照射到你的眼睛上。

The ceramic vibrates and creates a shockwave of air molecules that travels to your ear in 1.2 milliseconds.

陶瓷振動時會產生空氣分子衝擊波，在 1.2 毫秒內傳入耳朵。

Heat is picked up by fibers in your fingers that send a signal to your brain in 50 milliseconds.

手指上的纖維會接收到熱量，並在 50 毫秒內向大腦發送信號。

Three very different inputs, all processed in your brain at different times.

三種截然不同的輸入，在大腦中的處理時間各不相同。

You don't experience them separately, but as one smooth, simultaneous, and connected moment.

你不會將它們分開體驗，而是將它們視為一個流暢、同時且相互關聯的瞬間。

Your brain takes a moment to process and then invents a reality, a present moment that's not real.

你的大腦需要一些時間來處理，然後編造出一個現實，一個並不真實的當下。

What you feel is now is in fact a selectively edited version of the past.

你所感受到的現在，其實是經過選擇性編輯的過去。

You really only consciously experience the world 0.3 to 0.5 seconds after things happened.

在事情發生 0.3 到 0.5 秒後，你才能真正有意識地體驗這個世界。

Except this is also not really true, because your brain is editing time and space way more than that, and it makes decisions completely out of your conscious control.

但這也不是真的，因為你的大腦對時間和空間的編輯遠不止這些，它做出的決定完全不受你的意識控制。

You're living in the past.

你還活在過去。

No, future.

不，是未來。

No, a made-up future.

不，是虛構的未來。

Your present, what you experience right now, is kind of the future.

你的現在，你現在所經歷的，就是一種未來。

Imagine for a second that you're a table tennis pro.

想象一下，你是一名乒乓球職業選手。

In pro table tennis, balls whoosh around at 25 meters per second, which is pretty fast.

在職業乒乓球比賽中，球以每秒 25 米的速度嗖嗖飛過，速度相當快。

So let's slow down time.

讓我們放慢時間的腳步。

Light passes from the ball to your eye in nanoseconds.

光線從球到你的眼睛只需幾納秒。

It's converted into electrical impulses that reach your brain to be processed after 100 milliseconds.

它被轉化為電脈衝，100 毫秒後到達大腦進行處理。

Meanwhile, the ball travels 2.5 meters through the air, the length of the table.

同時，球在空中飛行 2.5 米，也就是桌子的長度。

If your brain showed you the past, where the ball was 100 milliseconds ago, it would hit you before you could react.

如果你的大腦向你展示過去，即 100 毫秒前球在哪裡，它會在你做出反應之前擊中你。

So instead, your brain takes its location, speed, and direction, and calculates where the ball should be in the future, by the time the information reaches you.

是以，你的大腦會根據它的位置、速度和方向，計算出資訊到達你的時候，球未來應該在哪裡。

And then it creates a fictional version of it.

然後再虛構一個版本。

This is what you see in your fake present, a fake ball that's somewhere else.

這就是你在假禮物中看到的，一個在別處的假球。

But you don't need to just see the ball.

但你不需要只看到球。

You want to smash it back hard.

你要用力把它砸回去。

If you acted now and started swinging your arm, you'd miss by a mile.

如果你現在就行動起來，開始揮動手臂，你會失之毫釐，差之千里。

Things are just too fast.

事情發展得太快了。

So before the ball even touches your opponent's bat, your brain starts predicting where it will likely be in space after they hit.

是以，在球還沒碰到對手的球棒時，你的大腦就已經開始預測對方擊球后球在空間中的位置。

Based on the other player's posture and your table tennis experience.

根據對方的姿勢和你的乒乓球經驗。

But as it can't be sure if it will be correct, it prepares multiple different responses.

但由於無法確定是否正確，它只能準備多種不同的回覆。

Maybe the ball will be here, or here, or even here.

也許球會在這裡，或者這裡，甚至這裡。

To be ready for all of these scenarios, your brain sends pre-programmed orders to the muscles you need to jump left, right, or up, telling them to be ready for any of them at a moment's notice.

為了做好應對所有這些情況的準備，你的大腦會向你需要向左、向右或向上跳躍的肌肉發送預設指令，告訴它們隨時準備好應對任何一種情況。

For a short moment, multiple ghost versions of you exist, all equally real inside your brain.

剎那間，你的大腦中存在多個幽靈版本，它們都同樣真實。

And then, as your opponent is about to lay into the swing, your brain decides on a single future that it thinks is most likely.

然後，當你的對手即將揮杆時，你的大腦會決定一個它認為最有可能發生的未來。

All but one of the ghosts are deleted.

除一個幽靈外，其他幽靈都被刪除了。

You only ever experience the ghosts that won, never the potential ones.

你只經歷過獲勝的鬼魂，從未經歷過潛在的鬼魂。

The order to the muscles to act out the winning movement is triggered even before the ball is hit back to you.

甚至在球被擊回給你之前，就已經觸發了肌肉做出制勝動作的命令。

You are totally oblivious to this.

你完全無視這一點。

By the time you consciously see the ball coming at you and decide to hit it in a particular way, your body has already hit it back.

當你有意識地看到球向你飛來並決定以特定方式擊球時，你的身體已經將球打了回去。

In reality, your brain already made all the decisions.

實際上，你的大腦已經做出了所有決定。

Your conscious experience is nothing more than an invented future, a prediction based on the information your brain received a fraction of a second ago.

你的意識體驗只不過是一個虛構的未來，是根據你大腦在幾分之一秒前接收到的資訊做出的預測。

This is not just true for extreme sports, like, um, table tennis, but also for walking.

這不僅適用於極限運動，比如乒乓球，也適用於步行。

Walking is time travel.

行走就是時間旅行。

After your game, you're walking back home, seemingly choosing your path and reacting to things.

比賽結束後，你走在回家的路上，似乎在選擇自己的道路並對事物做出反應。

Meanwhile, your brain is operating in three different time spheres at once.

與此同時，你的大腦同時在三個不同的時間範圍內運行。

It processes the sensory feedback of the past, it calculates the current state of your body, and it predicts your future, because walking is intense.

它處理過去的感官反饋，計算身體當前的狀態，預測未來，因為行走是緊張的。

Before the signal from your foot touching the ground has even reached the brain, it's already sent the order to your foot to make the next step, and it's already calculated the muscle patterns for the next two.

在你的腳接觸地面的信號還沒有傳到大腦時，大腦就已經向你的腳發出了邁出下一步的指令，並且已經計算出了接下來兩步的肌肉模式。

But what if something truly catastrophic happens?

但是，如果真的發生了災難性的事情呢？

There's a banana peel, and you step on it and slip.

有一塊香蕉皮，你踩上去滑倒了。

How did it get here?

它是怎麼來的？

Listen, don't worry about it.

聽著，別擔心。

It turns out your brain is ready for this.

事實證明，你的大腦已經為此做好了準備。

So far, we spoke of your brain making decisions for you, but this is not really true.

到目前為止，我們都在談論你的大腦為你做決定，但這並不是真的。

You don't have a central control room where the world comes together.

你沒有一個匯聚全世界的中央控制室。

In reality, different parts of your body are aware of different things at different times.

實際上，身體的不同部位在不同時間會感知到不同的事物。

Your spinal cord usually knows stuff before your brain, and even within your brain, different regions process the same event at different speeds and make independent decisions.

你的脊髓通常比你的大腦更早知道事情，即使在你的大腦中，不同的區域也會以不同的速度處理同一事件，並做出獨立的決定。

As your foot catches the peel, the gyroscope inside your ears notices a sudden change of your position in space.

當你的腳抓住果皮時，耳朵裡的陀螺儀會發現你在空間中的位置發生了突然變化。

It submits this information to your brainstem and spinal cord, the things-must-happen-quickly section of your body.

它將這些資訊傳遞給你的腦幹和脊髓，也就是你身體中 "必須快速發生 "的部分。

They immediately trigger emergency recovery patterns and send orders to different muscle groups.

它們會立即觸發緊急恢復模式，並向不同的肌肉群發出指令。

Within 200 milliseconds, pre-programmed sequences activate to catch your fall.

在 200 毫秒內，預設程序會啟動，接住你的墜落。

Your arms shoot out, your other leg stiffens to support your weight, your core muscles contract to stabilize you.

你的手臂伸出，另一條腿變硬以支撐你的體重，你的核心肌肉收縮以穩定你的身體。

100 milliseconds later, when you become aware that you're tripping, your body is already recovering.

100 毫秒後，當你意識到自己被絆倒時，身體已經開始恢復。

You are only just now catching up.

你現在才趕上。

Okay, so we've learned that your brain is constantly predicting reality around you, makes decisions about the best way to act, and then shows you an edited version, which totally makes sense, which you really want to be in charge of all that.

好了，我們已經瞭解到，你的大腦會不斷預測周圍的現實，做出最佳行動方式的決定，然後向你展示一個經過編輯的版本，這完全是有道理的，而你真的希望掌控這一切。

But your brain is not just predicting the external world.

但你的大腦並不只是預測外部世界。

Right now, it's predicting a way more complex thing, you.

現在，它正在預測一件更復雜的事情，你。

Are you just a prediction of your brain?

你只是大腦的預言嗎？

Why do you feel about the world the way you do?

你為什麼會對世界有這樣的感覺？

Your sense of hunger, your energy level, and especially your emotions are not just objective reactions to what state you're in, but predictions.

你的飢餓感、能量水準，尤其是你的情緒，並不僅僅是對你所處狀態的客觀反應，而是預測。

Your brain's prediction of what you'll need soon or need to be ready for.

你的大腦會預測你即將需要什麼或需要做好什麼準備。

You're probably used to getting food or going to bed roughly around the same time.

您可能習慣於在大致相同的時間吃飯或睡覺。

And as the time approaches, your brain releases hormones to prepare you, a self-fulfilling prophecy.

隨著時間的臨近，你的大腦會釋放荷爾蒙讓你做好準備，這是一個自我實現的預言。

You get hungry or tired because your brain assumes this is the time when this is needed.

你會感到飢餓或疲倦，因為你的大腦認為此時正是需要的時候。

This is the most striking thing about your emotions.

這是你的情感中最引人注目的地方。

They aren't just reactions to the outside world, they're predictions.

它們不僅僅是對外界的反應，更是預測。

When you go to a party, your brain isn't waiting to see how you feel once you get there based on how the party actually is.

當你去參加派對時，你的大腦並不是等著看你到了派對現場後的感受，而是根據派對的實際情況。

It analyzes your experiences of past parties and who it expects to be there.

它會分析你過去參加派對的經驗，並預測誰會參加。

Maybe close friends you feel safe around.

也許是你覺得安全的親密朋友。

Maybe people you don't know who are a less socially secure bet.

也許是你不認識的人，他們的社會安全感較低。

Maybe your brain remembers a party where you felt anxious and that experience stuck.

也許你的大腦還記得一次聚會，在那次聚會上你感到焦慮不安，而這種體驗也深深地印在了你的腦海中。

This can be pretty annoying.

這可能會很煩人。

If your brain predicts anxiousness, it adjusts your heart rate, hormone levels, and muscle tensions before you even enter the room.

如果你的大腦預測到了焦慮，它會在你進入房間之前就調整你的心率、激素水平和肌肉緊張度。

It prepares your body for anxiety, making you actually feel anxious, which then confirms the brain's prediction and gets saved for future reference.

它讓你的身體做好焦慮的準備，讓你真正感到焦慮，然後證實大腦的預測，並保存起來以備將來參考。

Does this make you feel like you're just along for the ride, forced to experience whatever predictions your brain feeds you?

這是否會讓你覺得自己只是在湊熱鬧，被迫體驗大腦給你提供的任何預測？

Thankfully, it's not quite like that.

幸好，情況並非如此。

Your conscious self is obviously not the decider of most things as you go through your day.

在你一天的生活中，你的意識顯然不是大多數事情的決定者。

But that is not what it's good at anyway.

但無論如何，這都不是它所擅長的。

Your brain and all of these different organ systems decide a lot of things, but they're more like butlers taking care of all the busy work.

你的大腦和所有這些不同的器官系統決定了很多事情，但它們更像是打理所有繁忙工作的管家。

You may not be in the driver's seat, but you are the passenger that decides where to go.

你可能不在駕駛座上，但你是決定去向的乘客。

What your conscious self is good at is long-term planning and abstract thinking.

你的意識擅長的是長期規劃和抽象思維。

It's a storyteller that tells the story of your life to your brain and to yourself, wherever the edges of these overlapping entities melt into each other.

它是一個講故事的人，向你的大腦和你自己講述你的人生故事，無論這些重疊實體的邊緣在哪裡相互交融。

You are able to see the big picture that your internal prediction machine could never begin to grasp.

你能夠看到你的內部預測機永遠無法把握的全局。

You are the part of you that can edit and write new predictions into the system.

你是可以編輯並將新預測寫入系統的一部分。

Sometimes you and your brain disagree on what's correct, but in the end, you are the person in power who tells the story about who you are in this world.

有時，你和你的大腦會在正確與否的問題上產生分歧，但歸根結底，你才是這個世界上講述你自己的故事的掌權者。

A story so convincing that you experience it as undeniable reality.

一個令人信服的故事，讓你把它當作不可否認的現實。

And as a happy accident, your conscious self is great at being happy about ice cream, fascinated by internet videos, and thinking deeply about Pokémon types.

意外的是，你的意識中的自己很擅長為冰淇淋而開心，為網絡視頻而著迷，為神奇寶貝的類型而深思熟慮。

What if you could train your brain to be more than just a regular butler?

如果你能訓練自己的大腦，讓它不僅僅是一個普通的管家呢？

Transforming it into a lean, mean, problem-solving machine with supercharged critical thinking skills and next-level intuition to help make your reality even more interesting and fun.

將其改造成一臺精幹、高效、解決問題的機器，擁有超強的批判性思維能力和下一階段的直覺，讓你的現實生活更有趣、更好玩。
