"Be nice, be forgiving, but don't be a pushover" I feel like that's something all of us can appreciate.
The nasty implications of this though, is that you might end up having 2 players that neither of them wanting to be nasty, but they end up being nasty because they don't know each other...
If they did, they would trust each other much more. And i believe that friendship is born right on that sweet spot when 2 or more "players" realize that instead of tic or tat, if I just trust that the other player is just as good hearted as I am, then maybe we are not 2 scumbags that retaliate with every opportunity, but instead trust that the other player is just like us, caught in this prisoner's dilemma situation...
I believe that the eye for an eye strategy of the tick for tat algorithm that kept winning everything, is a very bad life lesson for someone.
Turning the other cheek that was born with Christianity and other religions, is a testament to how much better it performed over thousands of years.
I might be an atheist, but I still acknowledge the good lessons that religions teach to people.
So I hope that people that watch this video actually understand that you SHOULDN'T be using these algorithms as a way of life for your life, no computer algorithm can simulate the near infinite complexity of a single Human life.
Turn the other cheek. You might very well be playing a copy of yourself, someone who wants to be nice but he / she might just be afraid just as much as you.
@Veritasium - this statement above should have been in your video.
I'm curious how much the philosophy would shift if the scoring system was adjusted. The current system does seem to reward cooperation as having higher utility than defecting as 3+3 > 5+0.
But what if the temptation was 6 points or even 7 points instead of just 5?
What does push over mean?
Also 'be consistent'
just like NATO.
Two people getting excited to meet each other because they both respect the others work is the most wholesome thing
Yeah. The excitable giddiness pops out.
A little island of cooperators spreading out!
This is refreshing. I just started reading Greene’s “48 Laws of Power” in order to understand how bullying parties win in negotiations - not because I want to do that, but because I’ve been on the receiving end of it and I want to better defend against at it. This mathematically proves that starting off cooperative, stating clearly your boundaries once they’ve been crossed, and willingness to cooperate again is the best way to go. That’s the way I try to live and want to live. This is helpful reinforcement of that. Thank you.
Just bear in mind that this is only relevant to two player games. N-player games are infinitely more complicated and the game theory math is different. Negotiating often isn’t just between two “players” but multiple.
@@seanjankowski9016 Do you have any examples of videos that dive into that subject deeper?
@@seanjankowski9016 I think that's why during the Cold War they divided it into West vs East, and those mutable concepts/groupings have pervailed till today. In globalization and progress towards unity, there will have to be negotiations and compromises, of which every every party that is concerned about not being dominated will likely be conservative towards progress. We've learnt how to deal with I vs Us through evolution (except for psychopaths and narcissists) but we're still learning how to deal with Us vs. Them. If there is just two prevailing identities that become salient through priming, then it becomes much easier to do Us vs Them, rather than Us vs Them vs Them vs Them vs etc... First it'll be West vs East, or Communism vs Liberalism, then it may become Empaths (2% of humans) vs Psychopaths (also 2%). What's considered "functional", or "pragmatic", will either move left or right (probably left). If we were to be more conscious, or even subconscious, of the existential race between empathy and psychopathy (universe-oriented interest vs self-interest), then we will have an easier time dealing with these two main ideologies that are competing on Earth. It used to be the environment, geography/ecology, that determined the evolution of humankind, but now it's becoming civilization, society and culture, that will determine the humankind's humanity and kindness, both genetically and memetically, 1 million years down the road, 1 billion years down the road... If we keep trying to move forward with what's Good for the Universe, then eventually we'll evolve towards "God". Both Objective Good/Evil and God/Devil are very ineffible, incomprehensible abstract concepts to the individual, but the objective of life does not have to be selfish-survival. Maybe life isn't "supposed" to be a game at all, like how the cells in your body are not in a "game" with each other. It's cooperation towards something bigger than ourselves.
That's why it's important to foster security. If you yourself feels secure, then you're less likely to adhere to a group identity to feel better off. Progressives are easier to negotiate a global culture, but eventually, even the most conservative of any "competitor", whether it be Japanese conservatives, Middle Eastern conservatives, American conervatives, African conservatives, etc... will find existential peace in this globalizing era.
Be aware though that this theory assumes equals and doesn't take into account power dynamics that are present in bullying. The victim can't tit for tat if it can't retaliate (defect) and is forced to constantly submit (cooperate).
Along with the points others have made, you have to consider that "deception" was not included in the game. The results "cooperation" and "defection" were considered fact and understood clearly. However, in the real world, there are many instances where it is not clear if a person or thing is cooperating or defecting. Thus, leaving the status of the relationship is unclear.
“You don’t have to lose in order for me to win”. Enlightenment
Now what do you do when the other person just wants to kill you?
Reflective principle. If you can manage to not be killed without killing, you'll reach your answer. That said there's nothing wrong regarding killing your immediate threat. That said most people will not use the option of de-escalation before a fight ensues
“In the short term it is often the environment that shapes the player… but in the long run it is the players that shape the environment.” Words to live by.

@Veritaserum, please make a followup video with ASYMMETRIC strategies, sexual dimorphism as an EXAMPLE
It's wisdom, not just knowledge. This is the kind of information that benefits the person who understands it.
LOL as if russians were ever rational. They hate West despite using its technologies and life improvement things. Is that rational? Ask yourself. Then watch russian TV and all yourself again.
So he continues to dissolve brains of the Western society. It's the second time I hear from him the narrative "give up to russia and China, they are dreadful!". How much do he cost in rubles?
I just love how enthusiastic Professor Strogatz was on seeing Professor Axelrod, like they were two good buddies
If you have dipped into game theory at all, meeting Axelrod would be thrilling. I think the only person that would be more exciting to meet would be John Nash, but he unfortunately passed away in 2015 and suffered from mental illness most of his life.
I guess it is like meeting the top1 player in your favorite sport.
@@leonig01 not just the top player currently, but a top all time player. Would be like meeting Gretzky, Babe Ruth, etc.
Who is Gretzky and Babe Ruth?@@Crushnaut
@@Kenny-yl9pc unless you wrote you comment on paper and mailed it to TH-cam, I think you can answer that question yourself.
This is what i am paying my internet bills for
we have free public wifi but is risky like aids.
The behavior of Tit For Tat is basically the foundation of the behavior of every social mammal species because it produces the best results for all. Some animal species are solitary, some are social. Neither survival strategy is necessarily better than the other, but Tit For Tat is a very simple algorithm that optimizes the social survival strategy.
We don't need magic to explain the existence of morality, we merely need to observe that humans are a social species rather than a solitary species.
Also, morality is the inevitable conclusion the moment you realize you're not the only one who experiences suffering. So I suppose there's that.
You assume all mamals operate on a man made principle is a very ignorant assumption on your part. You're also just wrong lol
@@kindenigma4119it doesn't have to be morality that drives this behavior like the video says, you could just be looking out for yourself and it would be the best strategy
Don't forget forgiveness and nice. The extra empathisis on tic it tac is ironically kinda zero sum
@@sirsanti8408 the comment above be said morality explicitly so what's your point if any?
THIS IS AWESOME INFORMATION!! Imagine if everyone would understand that cooperating and being kind and forgiving pays off best for everyone...
Well said ElectroBOOM.
Don't be a pushover! It's one of the most important fundamental rules that always gets forgotten when I hear sanctimonious leaders encouraging followers to act meek.
as in a "FULL BRIDGE" Cooperation, maybe ;)
I’ll cooperate with you ElectroBOOM, but I’m not holding onto those bare wires while you plug the other end in!!! 😉
Yeah well, People get betrayed(hurt) at a young age by people around them, at school, by friends or what they thought were friends, or even their parents, so what does that teach them?
One of the rare videos that should literally be watched by everyone.
not just this video, everyone should watch Veritasium's videos
It won't change the elites, who in turn will never be overthrown.
Why? Because you want everyone to think like you do? Sounds like a poor strategy.
what are you yapping about?@@McPilch
@@emmettkeyser1110it’s good for people to at least know of these things and choose if they believe them.
The important thing to note is that the GOAL is to accumulate points, NOT to 'defeat the opponent.' That is an absolutely significant thing to note.
This video is a literal hidden gem. May the future generation be reminded by this masterpiece hopefully
You’re literally just trying to get attention by posting a comment similar to the video thumbnail
And this is not a hidden gem, it's a video.
@@Stierenkloot nah sir I'm just fascinated by the video that's all
This is the kind of Veritasium Video I have been craving for. The one video which can change my perspective and connecting something abstract like maths to real life philosophies and mathematically proving it. Truly fascinating.
Don't read my name!!
Same actually. Has me reconsidering life choices as well
Seriously a top 5 Veritasium video IMO. really connects a lot of interesting topics and brings the philosophy down to a personal level
Give me an example@@CarlinTran
True, I was too waiting for such video for a long time that uses mathematics to solve our real world problems and give us a mathematical perspective of life
I think every parent should watch this. "Be nice, be forgiving, but not a pushover" is quite literally what I want my kids to grow up understanding. What a cool video
yes that 10% bonus for forgiveness it the skill to learn id say. its relatively easy to retaliate or forgive but finding that balance with a focus on forgiveness is what kids have to learn. (im 22 and thinking about gametheorie since 10 years or so. im getting better at it)
Kids who were taught to be always nice and never get involved in a fight, get bullied and become the worst people sadly.
It might be a skill to learn if that means you're learning why people defect and how to drop the need to retaliate.
It could be learning to let go of grudges which are really just deep seated emotions that are usually compartmentalized. Forgiveness is about not taking defection as a perceived personal attack.
This theory only works in 2 player games.
It is not a life lesson.
@@hippiehillape Even in the video, there were multiple "players" programs playing the game...
I almost didn't click this. I'm not even done yet and my mind is blown. Thank you for making and sharing this.
A superbly-produced video, if I may say so.
I find this fascinating. It confirms one of my favorite quotes, "do unto others 20% better than you would expect them to do unto you, to correct for subjective error".
Interesting quote
"Always leave a room a little cleaner than you found it".
This is by far the best comment on here!
@@SCORP1ONF1REbut then everyone would go blind from how clean all the rooms would be
@@_FJB_thanks!
Adding this to my list of "Best TH-cam videos of all time"
I also have that playlist
Top 10 greatest video ever but it's more tailored to my personality rather than objectively universally great like this video
Id love to hear some selections off of people lists

Me too but Subhan Allah Tit for Tat method has been mentioned in our holy book "Quran" :
وَقَـٰتِلُوا۟ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يُقَـٰتِلُونَكُمْ وَلَا تَعْتَدُوٓا۟ ۚ إِنَّ ٱللَّهَ لَا يُحِبُّ ٱلْمُعْتَدِينَ) {١٩٠})
Fight in the cause of Allah ˹only˺ against those who wage war against you, but do not exceed the limits.1 Allah does not like transgressors.
ٱلشَّهْرُ ٱلْحَرَامُ بِٱلشَّهْرِ ٱلْحَرَامِ وَٱلْحُرُمَـٰتُ قِصَاصٌۭ ۚ فَمَنِ ٱعْتَدَىٰ عَلَيْكُمْ فَٱعْتَدُوا۟ عَلَيْهِ بِمِثْلِ مَا ٱعْتَدَىٰ عَلَيْكُمْ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ) { ١٩٤})
Surrah Al-Baqarah Ayah 194 :
˹There will be retaliation in˺ a sacred month for ˹an offence in˺ a sacred month,1 and all violations will bring about retaliation. So, if anyone attacks you, retaliate in the same manner. ˹But˺ be mindful of Allah, and know that Allah is with those mindful ˹of Him˺.
The issue was we didn't follow islam well the last 200 years but those late ones we follow them well inshallah, and we will make our kids real followers may Allah help us.☝😊

this isnt matpat talking about fnaf lore...
Literally thought this was a send off video 😂
A small part of me was hoping he’d end the video with: “That’s just a theory, a GAME THEORY”
I was so confused because ive never heard of this before! I genuinely thought it had something to do with Matpat!
"Most of life is not zero sum" needs to be printed on a t-shirt (and every billboard the world over). Would solve so much destructive, envy driven behavior.
ayo its blenderguru
Except sadly this game theory mostly assume we are all equal in power which is definitely not the case IRL.
Some people might begin the game with +10 or something point which can secure their winning even if they play nasty.
Some people also might begin the game with -10 or something point which guarantee their lose, so they might ends up choose to play nasty to ensure the points gap not that big.
make donuts for prisoners
@@mardshima2070 good point about not starting equally. However, the gap between nice and not-nice strategies was pretty large, and it only gets larger over time.
@mardshima2070 power doesn't change anything. The only assumption made is that everyone benefits equally
The way Professor Strogatz was so excited when he saw Professor Axelrod genuinely made my night ☺️
"hey hey, and there's Steven Strogatz!" 🥹
Keep in mind these living legends are still, unfortunately, old, and therefore not as familiar with things like zoom. It's rather ironic, since their work may have inspired the very tools they can now use.
…You know, if we ever cure aging, I hope it also solves the difficulty older people have with learning about new technologies. I tried to explain the basics of videogame control conventions (e.g. that a lot of games use the same button for jumping) to someone at least one generation older than me. I got the impression that what I said made sense to them in theory, but that it wouldn't be retained

Timestamp for anyone else who wants to rewatch this wholesome moment after reading this comment
@@Twisted_Code I think that both of those professors that were coding when our own parents were babies can wrap their heads around things like zoom and video chat. I think it's just a bit of obsequious humor with each other
@@Twisted_Code Neuroplasticity (the ability of the mind to change itself) does have a downward trend with age... the vibrant old folks who embrace new things are rare. The reasons for this are partly biological, but partly to do with personality types, and the rabbit hole of how to measure psychological factors is a deep one!
Derek, you have climbed several notches in my regards. Your most unmissable video to date.
Presenting meaningful life lesson with a definitive mathematical proof is something only Veritasium could have pulled of.
Brilliant stringing of pearls of wisdom using behavioral economics. The 4 takeaways now hangs on my wall with the title "Talisman".
Thank you for bringing this treasure to the world.
Not only this sponser is brilliant, but this video too. I appreciate the amount of work that was put into this. Thanks!
Never did I expect to learn so much and be so inspired about probability, human psychology, life, and war. All that in just 27 minutes. Thank you Derek!
The most successful algorithm is just like how China responds to U.S. sanctions lol
its just overly psuedo intellectual. Feels very american to be told what to think. Just read plato yourself instead of watching veritasium. his video on concrete was a lot more fun when it didnt try to be deep.
@@adrianflo6481"overly pseudo intellectual"
My friend, I hope you know that you seem to be describing yourself (or atleast your comment).
It's a genuinely good video. Well researched, well structured, well edited. Content can be great regardless of medium. Don't you think?
From Derek always wanting to present things deeper than they are. instead of letting things speak for themselves.
the title of the video and the Intro for example. feels motivational and nature documentary. not scientific
If youve read the selfish Gene by dawkins you already know that the prisoners dilemma is somewhat the basis of genetic research and evolution. But in no way does it point to cooperation.
Compare this to Steve mould or Vsauce and at least i see clear distinction in the narrative.@@advitiayanand5974
TH-cam needs to put this on everyone's recommended like seriously.
Be nice! Math says so!
@@conradrogers317 Only if you have nice people to play with, I don't think that's true of our world anymore, at least not in some areas.
@@kirito3082 Absolutely, But the best for us. We never know what strategy the next person would chose to do. Only if we know it then we can modify our strategy accordingly. But this is gonna be beneficial in the long term, when you interact with too many people.
@@conradrogers317that's not what it says. It says 'don't be nasty'. Remember third point, retaliate. If someone is nasty, You can't be a pushower and be good
Sadly most people dont have the patience to sit thru a dense info vid. They are probably not so nice
I love what this guy put up on you tube. Really a very good youtuber. Your videos are great and the effort you put in your videos really shows how passionately you love this work.
This concept needs to be taught to every generation that comes along.
What an awesome, thought-provoking video! I’m reminded of this quote: “Competition is the law of the jungle, but cooperation is the law of civilization.” - Peter Kropotkin
I didn't expect to see a Kropotkin citation here ! here's another :
"in the long run the practice of solidarity proves much more advantageous to the species than the development of individuals endowed with predatory inclinations"
Those are some amazing quotes, now I have someone new to research!
@@johnr0417 he is a fascinating writer, not only was he politically very influencial, he also had a big impact by changing how we viewed darwinian evolution (at the time there were so called "social darwinists" who thought that individuals were just in competition with everyone else and didn't take into account collaboration, in the same way they tried to apply these theses to society to justify its state, for example by saying some societies, states, cultures, races, etc. were more legitimate because they were more "successful")
Absolutely. Too bad they don't understand religions more deeply... Turning the cheek meems shaming the oppressor, when read in the context of the time. It's more sophisticated than eye for an eye, and also, tit for tat vs all other strategies is not eye for an eye, eye for an eye against itself loses against that...
@@coenraadloubser5768 interesting, what is the difference between "an eye for an eye" and tit for tat in this context ?
I believe that humanity has gotten where it has through cooperation, not aggression. How delightful to discover that there is a theory that confirms this!
Exactly! Humans with no natural defenses except greater intellect were forced to cooperate in order to survive. Now I fear we’ve become so dumb that we as a species believe we no longer need each other :(
both cooperation and aggression. warring tribes, the rise and fall of empires and civilizations, have occurred since the dawn of time. without europeans colonizing the usa and basically committing genocide on the native population, would we ever have the industrial revolution that provided us the comforts of the modern era? it's all a paradox
It’s simplistic to say game theory confirms that cooperation is better than “aggression” because it doesn’t. What it really proves is *self interest* is always the best option, and that may take the form of cooperation, but often it does not. In fact, doing simulations of game in graduate school more often than not showed cooperation as a strategy only worked in the short term. Long term or endless games proved cooperation to be the least successful strategy, and those games where strategy changes showed it was only beneficial at the start of the game. Of course this is still theory and you won’t have a hard time at all finding articles one way or the other. It also depends on what the “game” is
hate to knit pick, but theories don't actually confirm or prove anything. Technically that's the whole reason they're called theories.
Really that's a fundamental principle of science, so maybe not so knit picky after all.
These replies are all on point. Life is very much a perpetual paradox; thats always the catch. Even quantum mechanics is stuck in this circle
Love when you can, fight when you must. This is an all time best You Tube. The Peace Process in game theory detail. Thanks.
This is one of the most educational videos I’ve ever seen and I love it so much more cuz of that. Grand video to watch! So much joy from learning good things.
The prisoner's dilemma and Tit for Tat being mostly the best and most enduring strategy is probably my single favorite fact about life. It's so encouraging that even at the unfeeling, strict field of mathematics, being kind pays off. It's like a hint that kind people are ultimately doing the right thing and, no matter how long it takes, we'll eventually come out on top. Even mathematics itself tells us to be kind. I think that's one of the most beautiful lessons in life.
It also highlights taking everything into consideration. If one is shortsighted and sees everything as a zero-sum game despite it not being so, of course that leads to adopting the wrong strategy.
“Be kind, don’t be a pushover and take everything into consideration” sounds like a decent motto for life
Love is the answer!
!!!
@@timelessadventurer Though it doesn't guarantee victory, at least not in this life...
But don't be a Pushover!
Cool that you named and showed the photo of Stanislav Petrov, we may all own our lives to this man!
A pretty underrated comment... think about it for a minute. Petrov truly was a man with a brain, not just with a finger. Google him if you don't yet know the entire story of 26th September 1983. May he rest in peace as he has saved the peace in the world (that time) - although, unfortunately, mostly unremembered today.
@@thomasstaudte653Yeah there should be streets, schools, hospitals and spacecenters named after Petrov.
It's not like there wasn't any framework for evaluating alerts of such kind.
The Soviets weren't idiots, even though everyone seems to pretend like they were.
Actually drunkard Yeltsin was told about the missiles and knew it couldn't be true, since we were at peacetime with Russia. He Ignored it and went back to sleep
Now we have moved from tit for tat in Ukraine, to being very forgiving. A real life test of responsive decision making.
This study is something that I can really relate closely to so many things that are happening around. Simple yet it gives a strong message.
Great video. First time on the channel but it's perfect. Sponsor message at the end is a big deal for me. Watched the ad instead of skipping it because it was in the beginning or the middle of the content I came for.
This may be your best video ever. The implications of this research are so vast and so impactful, I am saddened I have never encountered it before now. It seems like a major gap in my own education. As a psychotherapist, these winning strategies have a clear and immediate usefulness in therapy, and this research shows in concrete terms why these strategies are beneficial, beyond the merely moralistic appeal. Further, these strategies have massive social implications, especially when you start talking about the "noise" components. Those strategies that are willing/able to misinterpret a cooperation as a defection, and who then hold a grudge, are among the worst of all losers, and it seems that the social implications are pretty clear. But to be forgiving of accidental defections allows the system to be mutually beneficial. That is very powerful stuff, right there.
I recommend playing a short mobile game The evolution of trust by Nicky Case. In half an hour it gives such great insights through interactive simulationa
Fascinating stuff, truly enjoyed it.
I'm wondering to what extent can we apply this model to our environment and society.
For example, in the model, each relationship is independent but, in our society, behaviour and outcomes of a relationship with someone can have effects on the relationships with others.
Also, how would the results of this model change if we were to modify the arbitrarily set outcome values (3-3, 5-0, 1,1). Does the winning strategy change in a system where certain outcomes are more or less profitable? If it does, what set of values is the more representative of a human relationship? Or is each circumstance so unique that it is impossible to model a common set of values?
@Veritaserum, please make a followup video with ASYMMETRIC strategies, sexual dimorphism as an EXAMPLE
Has anyone considered the implications of modifying the rules, even slightly? I bet it's just as easy to win being nasty as it is nice, once the rules provide for those conditions. IOW, this "game" is really only proof that humans can become distracted by the results, and mostly ignore the fact that the rules were crafted to formulate such a result. IOW, we've learned nothing from this game, other than we live and die by the rules we make. Fascinating indeed.

People hate me because I am Muslim , Islam tells me to love people who hate me and never hate them back . But the problem is , my religion doesn't tolerate many things and doesn't accept different kinds of people . But neither tells me to hate them or harm them or even put distance between them and myself , they are just not acceptable to be Muslims and in most Muslim countries the things they do aren't allowed so other young Muslims don't follow them .
How to love them even though they hate me because my religion said don't do the things they do ?
How to prove to people that I don't hate them and I am not a bad person .
Because I know that Islam is portrayed as bad and misogynistic and that Muslim are seen as ignorant terrorist , and that women are treated like trash (even though it is quite the opposite , women must be treated better than how the man gets treated , men have to work but it is optional for them ) .
We are not bad why most of the world hates us , and think we are stupid because we believe in God, and they just think he is imagery , even though they know nothing about Islam, Muslim people and never tried to read the holy qouran .

As someone who's fascinated by evolutionary psychology it's amazing to see that game theory neatly explains human morality - because initially being nice combined with being forgiving but also sometimes seeking proportional revenge for wrongs is the optimal system of morals.

@@robert-rv8lo and how communism never really gets any better than capitalism.
@@robert-rv8lo, your comment makes no sense.
Capitalism, in many ways, IS the island of tit-for-tat goodness. It allows free exchange between people, and ruptures bridges among bad economic partners, but still allows for later reconnection. That island then grows outward.
Communism, by comparison, is a system that either requires everyone to switch in a single flash, or for its "not nice" nature to bully everyone into submission.
Furthermore, communism and even all systems based on "human rights" do not function, as they require all participants to be gaslighted into thinking all jobs are equivalent, even though one person is dancing up on a stage, and the other is down the sewers. At which point the sewer man is better off defecting. Lastly, communism requires central planning and is therefor prone to a lot of noise: wherein defectors can insert themselves, until they become the system.
where if you REALLY think about it communism needs capitalism otherwise how would we know if communism is the objectively correct answer

@@dogdjinn He refered specifically to the "Free Market", not to the economy in general. The free market specifically requires competition. In fact, if there were any cooperation, that's called "Crony Capitalism". e.g If all retailers in a specific sector of the market get together and decide to artificially raise the price on a product, so that, no matter what retailer you went to, you always payed the same price, that would no longer be a free market.

I'm shocked at how much inspiration a 30-minute video can give, in so many layers!
This is the biggest bs i have ever seen. Being nice in this simulation adds up to 6 points in total max, while being nasty adds up to 5 points in total max. And this is not a direct competition, so it doesn't matter who wins the battle. The end points are the things that are important instead. So the nice ones automatically get a 1 point advantage over the nasty ones. So before the start, the game is already mathematically rigged to favor the nice bots by 1 point. If you were to flip the numbers, then the nasty ones would have the 1 point advantage. Boom game theory solved. In reality, it's just bs. It's just simple probability.
The only real thing you can get out of this is that it depends on the environment on who'll be in favor. So, in one situation, it would pay off to be nice, but in another, it'd be nasty. It just depends on what option is more rich in points for both collectively in that situation. Still, that's just a simple probability that everyone knows anyway. It all comes down to both players knowing the potential point gain with either option, which with equal power would put you at an expected equal result. So yeah. Bs. It's just simple math with fancy words.
So this is a manipulation to promote cooperation for people who can't use math.
Why would anyone want to randomly push cooperation? And who exactly has that
intention? That's on you to decide.
@@Unity536 Fair point, the scoring given here has a huge impact on the outcome. And there is a reason why the points are given the way they are. If you go back to the original Prisoner’s Dilemma, and you see the outcomes of the actions they can take do you see why the points would be different and what they would be?
@@Unity536This is not a zero sum game. There is no total where you'd expect 6 = 6.
I find the scoring system to be fair. If nasty actions were given even 1 point extra there would be no reason to play nice at all. Whereas in this case, you really have a dilemma, to be nice or to be greedy.
@@sn0wbr33z3 I literally just mathematically explained through words why the nice ones have an automatic advantage and how the results are simple probability (it's rigged basically). You didn't even provide why you think what you think.
@@Unity536 where do you get the idea that "nice" strategies" add up to 6 points max while "nasty" strategies add up to 5 points max? Two participants who cooperate can score 3 points individually. Those 3 points are not summed up towards some sort of "nice" strategy pool. They are still competing against each other. I believe you are confused.

I like how he name drops the Soviet Union and suggests instant nuclear cooperation with them without even thinking about how that would impact the lives of people. As if they weren’t the nasty defecting types. The Soviet Union would very well still be alive if we’d gone full cooperation in 1945. They had half of Europe until 1989. They committed all the same atrocities the NSDAP did under the Axis powers and in 1933.

@@bullschitt3666meaningful competition necessitates cooperation. You can’t compete in something beneficial without cooperation. Opposing soccer teams may appear to be competing but they are also both cooperating. If both teams don’t cooperate by agreeeing on rules and agreeing to follow those rules and cooperating to allow those rules to be enforced to a certain degree then there is no game to be played. If one player just picks the ball up with their hands and punches their way to the goal and throws it in and then yells “GOOOOAL” they were neither competing nor cooperating. They were just being a dick. There is no competition without cooperation.
@@bullschitt3666 Competition is a form of cooperation. They cooperate in the field of advencement of understanding of a given subject. Ironically, competition in some endeavors is favourable to the whole more than cooperation would be.
I'm a bit irritated. I mean: the sole definition of "co-operating" is already to "associate with others in order to meet one's common needs and aspirations". So why should doing the opposite ever give any better results in that sense? Isn't that just tauto-logical ? - please correct me there.
@@AndreasitoI think you are correct, I think the point above just clears up what might seem to be cooperation, is not always defenitional cooperation as you described it. What in reality is being a pushover, a bully, or a dumbass might with careful framing seem to be cooperation. You can't decide whether someone is cooperative without asserting their environment.
Derek, what a well produced video this is. Probably one of your finest story-telling ones. Keep up the good work, team. This one landed really well.
except for the typo at 17:20
Key takeaway: being able to retaliate is essential, not just for yourself but actually it ends up being better for those who would just default to nasty if there were no retaliation, because at some point, without a reasonably fair justice system, everyone will go full nasty and everyone loses. Example: full breakdown of society/war
You've been neutered nicely
As a philosophy, we should default to forgiveness as often as we can allow and only punishment not in a sense of Revenge but as an example for the rest of society and for that person to inspire people to be "nice"
Incredible video, very interesting and well explained. Subscribed.
I learned about Axelrod's tournament from a Dawkins documentary that I never found again. I thought about it a lot and reached the same conclusions: open with trust, draw a strict line when that trust is breached and give people a second, third or fourth chance.

This video is amazing !! Well done done for creating it
Watching this video felt like a deep echo of the values my parents, teachers, and loved ones instilled in me from a young age. The emphasis on action and consequence, the power of forgiveness, and the ultimate realization that true self-interest lies in long-term harmony and cooperation felt remarkably familiar.
It wasn’t labeled “The Prisoners Dilemma” back then, but these ideas were woven into the fabric of everyday life. Whether it was the simple reminder to be kind to others because “what goes around comes around,” or the emphasis on learning from mistakes and starting anew, these lessons resonated with the core concepts of Karma, Kshama, and Moksha in Sanatana Dharma.
This isn’t about promoting any specific belief system, but about recognizing the timeless wisdom in fostering cooperation, forgiveness, and a mindful approach to life. In a world that often focuses on individual triumph, I believe it’s vital to instill these values in younger generations. It’s not just about navigating through games like the Prisoner’s Dilemma, but about building a future where cooperation and compassion are the foundation for success, both individual and collective.
So good! Thank you @aswani
There is just one problem with that attitude: it requires all players of the game to share the same basic values, if at varying levels. When you have players that don't, you run into the tolerance paradox: the other side factors in your basic nicety and will abuse you over and over again.
Capitalism emerged out of cooperation
It's just cold reading in the form of a video
This _blew my mind_ once I saw it in college, it's not an exaggeration to say that it's informed every choice I've made since, and I'm incredibly happy to now have a good resource to direct people to watch. Iterated games like this are _everywhere_
Great if it works for you, but the strategy is dependent on the game design...if the game was set up so that you get zero points to betray, and 2 points to cooperate, we would all be saying forgiveness is the key; conversely if the game gave 0 points for cooperation and 2 points for a betray, we would draw the opposite conclusion...there are many other variants you could design, and draw conclusions from them, but extrapolating to life is too simplistic. Simplest example: chess...how often does cooperation work in chess? Never. Doesn't mean cooperation doesn't work in life...Have a great one.
@@newstartt99 Have you seen the entire video?
Also, the setup here is giving 0 points for cooperation and 5 for betray... it's an even worse scenario than that which you propose and still the "be nice" algorithms win.
@@newstartt99 Well sure, it just turns out that many, many real-life situations have payoff structures like the classic prisoners' dilemma. (And chess-like payoff structures mostly occur in... games.)
Maybe - most situations have more than two players, of course - most of the time it pays to be "nice" to your team and "nasty" to the other team - it's deciding who is in your team that explains alot of human behaviour@@KevinRiggle
@@newstartt99 The chess example is very short sighted. Chess is a game with direct competition, the opponent can only be your competition and there is no incentive to cooperative. But in real life, there is virtually no situation like this other than in games themselves (like sports). Even in a situation where someone attacks you, cooperation (ex convince them to stop and they agree) is a viable option.
The video is just interesting evidence of the theory matching the reality. It's pretty obvious to any civil person that cooperating more than betraying in your daily life will lead to good outcomes.
Propably the best and most important video on whole TH-cam. Great job
I like this kind of videos where scientists are interviewed about their decades old work ( and maybe even reveal some undisclosed secrets ).
They are old but still mentally sharp - admirable.
So in summary. The best strategy in the long run is acting in "reserved good faith", trusting that other players will cooperate until they don't, then retaliate with the goal to push them into cooperating again.
Great video as always Derek. I wonder what results we can get from a multiplayer version of the prisoner's dilemma. With varying probabalistic attributes for each player that have an effect on the outcome. 🤔

The Game Theory on its own was really fascinating but the video and narration made it a lot better to understand and fully grasp the concept.
And to mention, the video itself is exceptionally crafted. I was not getting obliterated by the thoughtful results during certain points in the video and a narration afterwards. Rather the results and answers of the game were gradually revealed to get a hold of the unexpected outcomes of each scenario.
