1
Any time that you're interacting with another person who has their own interests and is trying to achieve their own ends, they are trying to do the best they can, given what they want.
2
You're trying to do the best you can, given what you want.
3
And so you're interacting in a strategic situation.
4
Game theory is a mathematical theory that attempts to make sense of how it is that people interact in these strategic situations.
5
John von Neumann wrote a very important book called The Theory of Games with a guy named Oscar Morgenstern.
6
And in there he laid out game theory.
7
Game theory is the study of decision making under conditions of uncertainty over time.
8
It was originally developed in economics in order to try and understand economic behavior, like why people buy certain things or why they're willing to work for certain wages.
9
But later on it was expanded and applied to a variety of different situations including biology,
10
international relations, and even interpersonal relations like friendship and parenting and family relations.
11
One of the things that game theory has really shown us through recent study has been interactions
12
that we oftentimes think as zero-sum or competitive are not as competitive as they seem.
13
In situations like in the Cold War, which most people thought, that's got to be a zero-sum game if anything is,
14
we discovered that actually there were opportunities for mutual cooperation.
15
Arms reduction treaties are a great example.
16
The U.S and the USSR figured out that if they could find a way to cooperate, they could both save an enormous amount of money and effort by reducing the number of weapons that they have.
17
Reagan and Gorbachev negotiated the START treaty with one another.
18
And one of the big problems that they had is, how can you be sure that while you're eliminating nuclear weapons, your adversary is also eliminating nuclear weapons?
19
So rather than saying, we're just going to get rid of some large percentage of our nuclear weapons
20
and hope that the USSR would do so as well, they broke up the interaction into a bunch of little tiny ones.
21
So the USSR would eliminate just a few nuclear weapons, then the US would eliminate just a few nuclear weapons.
22
They would check, and then they would go on to the next stage.
23
And then each would eliminate a few more, and they'd go on to the next stage.
24
This process of taking a big interaction
25
and breaking it down into little small parts can change a bad social dilemma into a positive interaction.
26
What I do in my personal life, and I think almost everyone can do in their personal life, is to try and think, in this interaction, what outcome would be good for both parties?
27
And how can we achieve that outcome?
28
And by thinking about everything in that way, we oftentimes transform something that seems like a situation where there has to be a winner
29
and there has to be a loser into one where nobody feels like they've lost and everybody benefits.
30
JOHN VAN NORMANN based game theory on a stripped-down version of poker.
31
In any given poker situation, you're dealing with a lot of uncertainty
32
and it's all about how to make the best decision in any given moment and that's so integral to life.
33
Everything we try to do, you know, should we take this route or that route, should I go here on vacation or there, it's all about dealing with uncertainties and probabilities of things happening
34
and poker is a very fun and easy way to teach someone how to do that.
35
First rule of thumb is how to extract the most money
36
or chips from your opponent when you have a strong hand
37
and how to lose the minimum when you have a weak hand.
38
You're never going to be 100% certain where you are, are you beating them or do you have a worse hand.
39
So you have to sort of construct a strategy that is mathematically optimal in each situation.
40
The most damaging bias that can come up in poker, and I also think very often in life, is the sunk cost fallacy.
41
Where you'll have a lot of chips, perhaps almost all of your stack is in the middle,
42
and yet you are 85 to 90 percent confident that you have the worst hand.
43
Putting another chip in the pot is probably not a good idea, but we'll often go to ourselves, Ah, well, I've gone this far, I've put this much in, I might as well see it through to the end.
44
But if you have very strong information that actually from this point onwards, putting more money in the pot is a bad idea, then you shouldn't.
45
But we have this belief that, well, I've put this much time in or this much effort, that we should continue on.
46
That can be very, very costly.
47
Once you start paying attention to the sunk cost fallacy, once it's on your radar, you'll probably notice at least a few things that you wish you were doing differently.
48
Those might be small scale.
49
In my case, I'm now much more willing to abandon a book
50
that I've realized I'm not enjoying and not getting any value out of,
51
rather than trudging dutifully through the remainder of the book just because I've already come 100 pages.
52
These changes might also be large scale.
53
For example, I was in a PhD program and at a certain point
54
realized with increasing certainty that I wasn't happy in this field and would probably be better off switching.
55
And that the only reason
56
that I had stuck with it as long as I had was
57
because of my fear of confronting the sunk cost of four to five years
58
that I'd spent preparing for and working in the PhD.
59
And sometimes it really does take time to fully acknowledge to yourself
60
that you don't have any good reason to stick with the job
61
or PhD or project that you've been working on so long because sunk costs are painful.
62
But at least having the sunk cost fallacy on your radar means
63
that you have the opportunity at least to push past that
64
and make the choice that instead will lead to the better outcomes for your future.
65
Game theory spent much of its early days analyzing zero-sum games where one party is going to win
66
and the other party is going to lose and trying to figure out what's the best strategy.
67
What game theorists have figured out is
68
that in zero-sum games the best strategy to pursue
69
when you're against a sophisticated opponent is to adopt the strategy which minimizes your maximum loss.
70
This is sometimes called the mini-max strategy.
71
So the idea is you think, what's the worst case scenario for me?
72
What could my opponent do that would make me worse off?
73
And then you figure out what's the best strategy against that.
74
So you're minimizing your maximum loss.
75
Game theorists prove that if you use this way of thinking, minimizing your maximum loss, you ensure that no matter how sophisticated your opponent is,
76
you've guarded against the worst case scenario.
77
And not only that, but in zero-sum games, you've done the best you can possibly do.

이 비디오로 영어 회화 연습을 하는 이유
이 비디오는 게임 이론이라는 전문 주제를 쉽게 설명하면서도 일상적 의사소통에서 중요한 전략적 사고를 담고 있어 영어 회화 연습에 매우 적합합니다. 복잡한 개념을 간결하게 전달하는 표현 방식은 영어 쉐도잉이나 shadow speech 연습에 최적화되어 있어, 듣고 바로 따라말하는 능력을 키우는 동시에 논리적 표현 능력도 향상시킬 수 있습니다. 특히 '상호 협력', '최소 최대 전략' 등의 용어를 자연스럽게 사용하는 모습은 전문적이고 명확한 영어 표현을 익히는 데 큰 도움이 됩니다.
문맥 속 문법과 표현
- "attempts to make sense of how it is that people interact" - 'how it is that' 구문은 복잡한 관계를 설명할 때 유용한 표현으로, "사람들이 어떻게 상호작용하는지 이해하려고 시도한다"는 뜻입니다. 회화에서 원인이나 방식을 강조할 때 자주 사용할 수 있습니다.
- "breaking it down into little small parts" - 'break down into'은 "~로 분해하다"는 뜻으로, 복잡한 문제를 해결할 때 자주 사용되는 표현입니다. 이 비디오에서는 군비 감축 협상의 예로 사용되었는데, 일상에서도 "프로젝트를 작은 단계로 나누다"와 같이 응용할 수 있습니다.
- "minimizes your maximum loss" - 'minimize maximum loss'는 "최대 손실을 최소화하다"는 의미로, 게임 이론뿐만 아니라 경제나 일상 결정에서도 자주 사용되는 전문 용어입니다. 형용사와 명사의 조합으로 명확한 의미를 전달하는 방식을 익힐 수 있습니다.
발음의 함정과 영어 발음 교정 팁
이 비디오에서 주의해야 할 발음은 "Morgenstern" (모르겐스턴)과 "dilemma" (딜레마)입니다. 특히 "dilemma"는 'i'가 길게 발음되며, 마지막 'a'는 약하게 발음해야 합니다. 또한 "sunk cost fallacy" (싱크 코스트 패러시)에서 'sunk'는 [sʌŋk]로 발음하며, 'fallacy'는 [fæləsi]로 끝 부분이 약하게 처리됩니다. 영어 발음 교정을 위해서는 이와 같은 전문 용어의 발음을 정확히 익히고, 영어 쉐도잉을 통해 발음과 리듬을 반복 연습하는 것이 중요합니다. 비디오를 여러 번 듣고 따라말하면서, 자연스러운 억양과 강세를 체화시키세요.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
