You'll Never Win This Game

- The transitive property is ingrained in our thinking. It gives our brains a simple, straightforward way to process the world -- especially with numbers. If one thing is better or more valuable than another, and that second thing is better than a third, you KNOW that the first one is better than the third.
But it doesn’t always work that way. And if you fail to recognize when real life violates the pattern of transitivity, you’re going to run head first into a veridical paradox.
Efron’s non-transitive dice demonstrate that hard and fast rules about value don’t always exist. By toying with relative probabilities, Efron discovered that a die’s superiority or weakness can be relative -- and as the dice values get more complex, it becomes nearly impossible to reason out which die is stronger against the others.
In math, our first impressions are often deceptive. Occasionally they’re just plain wrong. And sometimes a game is designed to deceive you into believing you’re in a position of strength when there’s no way to win. That’s the deception paradox.
Oh -- and if someone wants to play a game with you and they let you go first… run.

Rock/paper/scissors is mathematically trivial; its intransitivity is obvious and needs no explanation. Efron's Dice have unequal features with varying average rolls and a transitive/higher number wins aspect to the game. Also, a die's advantage as we add more dice approaches a limit of 3/4, which is pretty interesting. R/P/S has none of this complexity.
I'm sorry that there's so many people complaining in the comments. I found this video a bit interesting even if I did somewhat catch onto the trick early on, and, either way, the video still has value
lol
That just sounds like Rock Paper Scissors with extra steps
I mean your basically sayin I can't win cause I'm goin 1st it's kinda like da thing wit rpgs or pickin a starter Pokémon where they beat each other in a circle
rock paper scissors has none of the complexity, but all the layman parallels.

Seems like his D did crush something

wow
should've ended the video there to be totally honest
"Let's play rock paper scissors, but you get the advantage of picking first and letting me know what you picked."
I was thinking the same thing lol
You completely missed the point of the video, it's not rock paper scissors. The rules for winning rock paper scissors are completely non-transitive while the rules for winning this game are transitive. If you roll the A dice and beat the B dice, which beat the C dice, which beat the D dice, the A dice should have the highest number and beat C and D. But it doesn't. But there's a simple explanation for that. That's why it's a veridical paradox, a paradox that seems like a paradox at first, but has an explanation
@@michaelmiller2210 No, the *NUMBERS* are transitive (1
@@unliving_ball_of_gas my guy, the point of my comment went right over your head. I know numbers are transitive and I know the dice aren't, I implied that in the previous reply, you just completely missed it. The point is, rock paper scissors isn't transitive at all, while this dice game seems like it should be transitive at first since it uses a transitive ruleset rather than a non transitive one. It's a veridical paradox, Kevin said it himself in the video. People just think they're smart because they understand that the dice are non-transitive, when they actually just have no clue what this paradox is.
@@michaelmiller2210 Yesh, I understand it, I thought you didn't understand the paradox so I tried explaining it. Well, at least it might make someone else understand.

The most confusing part of this video is you trying to convince us that this is somehow unintuitive.
Yes
yeah, I just looked at the dice, compared the numbers in my head and could easily see which dice were good against the others. It really was obvious when he said "you get to choose first". If this were a true blind pick, then things would be far different. If I told you to play rock paper scissors and that I got to pick after you did, you would say no. That is the real problem here in part. The other part is assuming this is a single game. It is not. He requires a series of games to have absolute victory. If it were a single game, I might still win, even if the odds are against me. But after rolling the dice 20 times I am clearly going to lose more than I win. I'm not impressed if this is the best an award winning statistician comes up with as some sort of mind bending puzzle.
Or Pokemon type advantages, we're taught from a pretty young age to understand this sort of concept...
Maybe Vsauce2 is trying to target, and cater for, a less intellectual audience. ¯\_(ツ)_/¯

So what happens when you roll all 4 dice in a 4 play free for all? Over time, which one wins?
Ive written a script and it seems like its a _very_ close call with C and D - D is a _little_ better. Then followed by A and the worst is B.
@@leobozkir5425 What about a 1v1 with blind picks where you don't know the opponent's choice beforehand? excluding cases where both players pick the same dice, that's an obvious case.
The overall chart would be 1296 deep, but we can simplify it logically. The following is for the SIMPLER dice.
1. C wins if C rolls 6. This occurs at 1/3.
2. D wins if D rolls 5 and C rolls 2. This occurs at 1/2 x 2/3 = 1/3.
3. A wins if A rolls 4, and both C and D roll sub-3. This occurs at 2/3 x 2/3 x 1/2 = 4/18 = 2/9.
4. B wins if all others roll sub-3. This occurs at 1/3 x 2/3 x 1/2 = 2/18 = 1/9.
Thus, C and D are equal, followed by A, and finally B.
As for the blind picks (a later comment), you simply average each chance of winning.
1. A wins 2/3, 4/9, and 1/3 of the time, for a total of 13/27 (26/54).
2. B wins 1/3, 2/3, and 1/2 of the time, for a total of 9/18 (27/54).
3. C wins 5/9, 1/3, and 2/3 of the time, for a total of 14/27 (28/54).
4. D wins 2/3, 1/2, and 1/3 of the time, for a total of 9/18 (27/54).
So C has a slight advantage, and A a slight disadvantage. This could introduce psychological factors - will you pick B anticipating that I'll pick C?

Imagine playing rock paper scissors but one player chooses first. Yes, they'll always lose
The funniest thing is he said most of the time, imagine losing a Rock Paper Scissors game when your opponent went first, even if it is 1/1000
Also, as the top comment points out:
The way you win rock paper scissors isn't transitive (if it was, this would mean if paper beats rock, and rock beats scissors, then paper must beat scissors) but the rule for winning this game (rolling the highest) number IS transitive (i.e for any 3 numbers, if number a is greater than number b, and number b is greater than number c, then c MUST be greater than a, this is true for all numbers in the entire world). That's why it's weird that the dice you pick do not satisfy a transitive realtion (i.e if one dice out preforms another which out preforms another, the first dice does not nessecairly out preform the last) but the rule (greatest number) that decides if you win the game DOES work like that ( if one number is greater than another which is greater than another, the first number is always greater than the last)
@@noahmanc2 And also you need to point out that, most of the time when one dice wins, it wins by a lot, but when it loses, it loses by a little.

@@noahmanc2 paper can cut through scissors
I feel like most people don't assume transitivity.
And I don't think the non transitivity is that mind boggling since because a "worse dice" can win small while loosing big and it doesn't make a diffence.
Agreed, he stated the problem then gave a bunch of misleading assumption
Agreed too ... When he stated that dices "battle" are transitive I was a bit shocked, it clearly isn't something to assume from thin air if you did a bit of math in your life.
I’m a very visual person, for the record (which correlates to how I wrap my head around these things). I feel like his assumption of transitivity is based on an assumption that most people will see this (or similar scenarios) very linearly, which isn’t true. Yes, the transitive property is a proven property, and this does qualify as being a mathematical paradox, but it doesn’t need to be confusing in actual practice. He/We just have to change how we see it. Instead of seeing it as a line, see it as a circle. It’s like the game “rock, paper, scissors”, which is structured off of a triangle - rock beats scissors, scissors beats paper, and paper beats rock. That makes sense, we all understand that. This is the same thing - A beats B, B beats C, C beats D, and D beats A. There you go, makes sense. The only difference to understand, then, is that there are no laws of averages. Even though D beats A MOST of the time, we’re still playing with dice. A could absolutely win, just by rolling well. Still a game of chance, in the end.
Also, random thing, but the way he painted D as winning 10 times and A winning 5 times feels misleading (though it might not have been intentional). It paints this very strict scenario where the math will go perfectly, which isn’t true. It’s still just a roll of the dice, in the end, in a game where the highest roll wins.
@@TheUltraUltimatum just a theory, but, and hear me out on this one, maybe that's why he named the video "the deception paradox"?
"I'm going to give you a game-changing hint." *lies*
He never said A beats D though, he just said you may assume that A beats D. It's kinda like rock paper scissors. Plus if you look at the numbers, it would be obvious D loses to A

@@baconheadhair6938 It "covers" rock by wrapping around it. Not really that big a threat compared to being cut in half or shatter to pieces. Never made much sense to me. Honestly seems like it would do more damage to the paper than the rock.
"Rock, paper, scissors, a very strange game. The only winning move is not to play. How about a nice game of global thermonuclear war?"
transitive property makes zero sense in this example as it's all about matchups. Total value is pointless to look at as well. It's not a paradox, it's just looking at the problem compeltely wrong and then making it out to be more than it is.
Welcome to VSauce2!
I came to the same conclusion. I stopped the video and made my own opinion and found it out in less than 2 minutes max, it's really not that hard to win this dice game.
Yeah, you can work it out just by looking at the dice in the first place without all the charts lol
Its counterintuitive to the most who hear it. Thats what makes it a paradox! Its not a logical paradox, its a psychological paradox (veridical paradox)

At 69 likes so I can’t like it
I feel like as someone who has played hundreds of hours of Pokémon in my life, this concept is familiar enough to something I’ve experienced for so long that it makes pretty decent sense.
While sure Pokémon has been called a traditional “rock paper scissors” for decades, like this game it’s far more complicated. There are 19 types, all weaving in chains and webs of one beats the other beats the other, with some traditional RPS triangles, as well as complex chains where fire beats grass beats water which beats both rock and ground and is resisted by steel, and then that ground is also good against the rock as well, steel and fire which is against fire. It’s hit many complex layers and branches that dictate where something lands on a winning matchup.
Ice for example is one of the worst defensive types with 4 weaknesses, but offensively it crushes dragon, grass, ground, bug and flying.
The first batch of numbers was so incredible easy to work out, it makes perfect logical sense. Should have started with the second set of numbers to make it at least somewhat difficult to work out.

the part that's unintuitive is *why* it works. it may not be hard to wrap your head around, but presented a different way you could easily fool a lot of people. which is...kinda the point i think. i think, in this case, kevin is jsut a victim of his own success. everyone expects the twist, so they know not to just...go with their instinct.
@sillyking1991 that's not the problem. The problem with this video is he intentionally is deceptive about how it works to force the twist. The dice itself are an interesting way to show non transitive properties, this video is not. Kevin acts as if everyone assumes that "Well #1 beats #2, and #2 beats #3, so obviously #1 always wins." People learn rps at a very young age. The fact that something is nontransitive is not a twist in any way.
Lmao this is exactly like rock paper scissors and Kevin's like "I'm so nice that I'm going to let you make your move first". 🤣
Not really. If it was like Rock, Paper, Scissors, then you'd be able to choose scissors and be beaten by paper. In the video he shows that he opted to choose the overall statistical weakest in the face of the strongest and still managed to have the advantage.
3:02 "I'm using D to go against your A, and I'm going to CRUSH you" 😂

its just rock paper scissors with extra steps. completely logical
Yeah. It is pretty much the basis of a lot of card games. Not the individual cards, but hands of cards.

Because the first player has no way to pick the best choice, in this game whoever's plays first will always lose (if the second player chooses the best choice in the situation)

25 years of playing Pokemon, and 20 years of playing tabletop RPGs have made this a very easy concept for me to grasp. The moment I was picking first, I already had a good idea of what was up. I was just like, "oh, this is going to be non-transitive dice... Yep, called it."
"Only the Sith deal in absolutes."

This seams almost misleading, it is very obvious immediately that D beats A. It makes perfect sense, just look at how many sides on one dice beat the side in the same position on another dice.
Well yeah it's obvious after you compute that D tends to beat A that D tends to beat A.
@@Adamant- Yeah, that's what he said. The point this video tries to make is that it's some big surprise that this is the case, but it isn't. It's pretty obvious just from looking at the dice that they aren't transitive. It's just a weapons triangle or rock paper scissors. So it's 9 minute explanation of an incredibly obvious concept.
This is really the weak part of the video. No one is surprised that D beats A. Anyone who actually sat and thought about it would realize this.
Title - "the *deception* paradox"
Complaints in the majority of responses "hey, you were deceptive by tricking people into assuming this should be transitive"
yeah, he framed it as a chain of "this is best" but before he even mentioned that, i assumed the last one would beat the first, because thats of course how its going to work.
You can even see it from the number plots, all of D's numbers are better than A's by like, one. cool video puzzle but still, kinda missed a big piece that we the audience arent dumb :P
Except I never assumed that, even when he said why it should...
Ah, so he was using French grammar?
This is the equivalent to telling someone to go first in rock paper siccors
@@moth2910
Yet virtually nobody could be fooled into thinking that Rock Paper Scissors is transitive... where as many people could be fooled into assuming all dice are transitive.
So, not it isn't equivalent. The chances of winning is equivalent, but the chances of deceiving someone isn't equivalent at all.
Which goes back to my comment about this being called the *deception* paradox.
Your Videos are the greatest they are energetic and they learn us a lot of thing! Keep doing these!!!
So it’s like playing Rock Paper Scissors but with 4 hand gestures and I get to see what they do first. Love it.
This game doesnt have an OP meta, just hard counters to everything
The only problem I see is being forced to pick first; if both players picked randomly and revealed at the same time, then it (should) be random who wins.
This whole "paradox" relies upon a nasty mangling of the transitive property.
All of the comments on this video are "it's basically rock paper scissors but you have to pick first and show me your answer" or "the strange part is how you're trying to convince us it's unintuitive". It IS unintuitive to people but when demonstrated in such a clear way people don't see how they are still falling into this trap.
Take a game like League Of Legends, look at the sheer amount of tier lists the community has made or how even pro players build the same item build every game because "It's the always the best", things like this fall into the trap. A tier list inherently says S tier is better than F tier while ignoring factors like matchups, meta and etc. an F tier hero can counter an S tier hero and now the tierlist is broken. Despite that we still see it being used by nearly everyone in the community.
Alternately we could look to Magic The Gathering or Hearthstone, what's the best deck? does that deck beat everything? of course not that's essentially this point Kevin is trying to get across here.
I love the quote he uses to sum up the video "We fall into a cognitive trap in thinking in absolute terms when real value is often relative. In this game the concept of better or worse is deceptive, it depends entirely on the situation. Our brains want to find patterns to identify "The Best Choice" and we love ranking things, But life isn't always transitive". the above examples show how the majority of people fall into this trap and while the comment section here say they don't, a lot of us probably do without even knowing it.
In any strategy game with multiple choices, learning how matchups interact and how you can perform in certain scenarios with something will almost always be better then just always picking what might be the objective best. Nothing is without weakness, and if you can abuse their weaknesses, it matters not how weak something is in it's own right. Situational awareness is key.
So basically Rock Paper Scissors, but you get to see what your opponent picks beforehand.
I was about to say that, doesn't seem so special after that, does it.
@@undercatviper I wouldn't say it's not special. It's still a pretty unique mathematical property. But it's not as confusing as it seems at first.
not exactly, because the whole concept of rock paper scissors is intransitive, where as here, numbers are transitive, just the collection of them forming the dice aren't
this is exactly my thoughts put into words, thank you for explaining it so well XD
Ehh just because numbers have transitive properties, that doesn't mean that sets of numbers do.
There's no weak or strong, there's only counterpicks
I just think about it as A>B>C>D and then repeat a little, which gives A>B>C>D>A>B… giving the reasoning on why D beats A. Its more of a pattern than anything else
I understood the system almost instantly. It's just the total number of higher digits on the dies that make the difference. Very cleverly made!

This is like when no matter which starter you pick in Red and Blue in Pokemon, Blue always picks the pokemon stronger against you. In this scenario, It's actually better to pick your dice after your opponent does.

Im sure you can explain something like why the golden ratio is the way it is, but can you put this into words?
@@jemangerrit1747 The way the numbers are set up. C's numbers are all better than D's, when comparing strongest with strongest and weakest with weakest. B beats C's weakest, which is more likely, while A's strongest beats B. A, however, still has numbers lower than D's. This is just a simple case of rock paper scissors with RNG to it. B is what makes the importance, having only one number to have the loop work.
@@dropthehatantonycraft7516 this is a fair explanation. However I think its a little bit naive to call it a rock paper sciccors game. RPS is purely non-transitive. What makes these dies special is that it works with numbers that are inherintly transitive. I also calculated that C beats A, which isnt on purpose I think, but is that way because of the numbers. Also, the loop doenst work because of B, since in the harder example it has multiple different values.
If A had five 4s and one 0, it wouldnt work. So theres a delicate balance that I cant put into words without straight up calculating it.
And that is why, while not being mindblown by it or anything, I can admit I didnt REALLY understand it "at first glance"
Suggesting that this is transitive and that the highest number combined means anything is misleading and kinda insulting to viewers who see it is definitely not.
I mean you can easily overlook the transitive part but even a 6th grader won't fall for the sum argument because a 1-1-1-1-1-1 beats a 0-0-0-0-0-9999 83% of the time.
thats why he removed the simple dice and replaced them with ones that were *faaar* less obvious.

They're non-transitive dice. We're just playing rock paper scissors with dice. And you're letting us go first...
That's so smart, letting your opponent go first in rock paper scissors
Actually C is still the best dice but not just because it has more points and it’s the same for A which is the worst, let me explain :
Let’s evaluate every probability of each matchup :
A wins against B : 2/3
A wins against C : 4/9
A wins against D : 1/3
A wins against a random dice between (B,C,D) : 13/27
B wins against A : 1/3
B wins against C : 2/3
B wins against D : 1/2
B wins against a random dice between (A,C,D) : 1/2
C wins against A : 5/9
C wins against B : 1/3
C wins against D : 2/3
C wins against a random dice between (A,B,D) : 14/27
D wins against A : 2/3
D wins against B: 1/2
D wins against C : 1/3
D wins against a random dice between (A,B,C) : 1/2
So we see that C is the best choice, B and D then, and the worst one is A.
Note : Of course if you’re opponent can choose his dice he will always wins 2 over 3 times but C is better if he can’t choose.
For a simpler version of this game, Imagine you are playing Rock-Paper-Scissors against someone, but you get to see what your opponent is choosing before you choose.
I imagine Fighting Game players would have an easy time understanding this. Plenty of cases where a "strong" character has a really weak matchup against a "weak" one.
This
and then that character becomes the main counter

Yeah the concept is easily understandable but the thing is that the mathematical total is useless since beating somebody 6-1 is the same as beating them 2-1, so how far apart you beat them doesn’t matter; not crazy to grasp but I see what he was trying to say
Rock beats paper and paper beats scissors?
What i want to know is, does A also lose to C or is it just D? Also, does B lose to D?
I get the A and D part, but he never explained if the whole thing is none transitive or is just the A vs. D that isn't transative...
Please, I need to know! this will keep me up at night!!! Well probably... for like 5 mins or so anyways. I still really wanna know though.
@@raincandy3 You sayin you *don't* play it like that?
I think it would be worth mentioning that as much as A>B>C>D is valid, so is B>C>D>A and so on. There might be merit in thinking of the "dominance" as more of a cycle than a chain with definite starting and ending points.
Also, D>A seems to hold just as well for the simpler dice:
1 1 1 5 5 5
0 1 1 1 5 5 5
0 1 1 1 5 5 5
4 4 4 4 5 5 5
4 4 4 4 5 5 5
4 4 4 4 5 5 5
4 4 4 4 5 5 5
"You *Most likely* will not rationalize this paradox" I figured everything out in less time than you took to finish the game....
The thing about this is that the relation isn't transitive. So no paradox
Edit: One more thing to people that say that the higher number wins and that relation is transitive. Yes, it is transitive but Kevin never told us that the higher number wins he just showed some tables and showed A beats B, B beats C and so on. He mislead us by putting A ">" B symbols so that we think the relation is transitive. He should have just said A "beats" B and the relation "beats" isn't transitive.
But the rule to win the game is transitive. (The "greater than" realtionship is a transitive realtionship, if number a is greater than number b, nd number b is greater than c, then we know a is greater than c. Thats a MATHEMATICAL rule). Thats why its "paradoxical" (although not a true paradox). Many people are comparing this to games where the way you win is NOT TRANSITIVE (like rock paper scissors) which is why some people are missing what's "confusing" about this
Exactly my thought!!! He keeps hinting as if the relation is transitive when it's not. For the first 3 minutes of the video, he keeps talking as if the relation is transitive and leading people into thinking that it is, when it's obviously not. The whole thing about A > B & B > C & C > D => A > D is just wrong when the relation is not transitive.
@@IsmailTaleb ...the rule to win is transitive.
You win by rolling a higher number than the other person. That realtionship is most certainly transitive. If a number A is greater than a number B, and B is greater than C, then you know for a FACT A is greater than C.
The paradox arises in that, that the rule to win is transitive but the dices you pick are not. The paradox isn't that they SHOULD be transitive. Its that, a normal human would derive from a game where the rule to win is transitive, that the matchups are also. You would greatly struggle to find another game where the rule to win is transitive but matchups aren't.
Its not technically a paradox, but alot of people are completing missing why its confusing. Its not confusing that its a game of matchups, there is plenty of games of matchups. Whats confusing is DERVING that fact from a transitive rule.
@@noahmanc2 I'm afraid that is not the definition of transitivity my friend. We can take the definition from a math forum or Wikipedia for the sake of this argument : "a relation R on a set X is transitive if, for all elements a, b, c in X, whenever R relates a to b and b to c, then R also relates a to c".
Now, on this video we have a bunch of relations between pairs: a>b, then b>c, then c>d, then d>a (this last one he doesn't say explicitly, but it's there) but since this relation is NOT transitive, we can never put them all in our relation as a>b>c>d (this one is wrong).
I believe the confusion happens because we consider a, b, c and d to behave like numbers, but they are not, they are dice. So the relation ">" is not the "regular" relation > that we know applies to numbers, this is another relation ">" that we just defined for the purpose of this game. So we should not use it, and I believe that's where people get confused and they think that ">" in this example is the same > we use to say a number is greater than another number. So yes, as Abhjitih S and I said earlier, this new relation ">" is not transitive, unlike the > relation that is transitive when it comes to numbers. There is no paradox.
@@IsmailTaleb dude, I majored in abstract algebra... You're not about to tell me what transitivity means. If you really don't think the integer greater than relationship is transitive you can literally Google it.. its not a hard proof to understand.
Nobdoys saying the dice are numbers. But what decides if you win the game or not IS a number (the number that is rolled)
You seem to think im saying the matchups are transitive. I am not . I am talking SPECFICIALLY about the rule that decides if you win the game or not.
Your missing the point of the video. The point isn't that the matchups should be transitive. Nobodys saying that. The point of the video is realizing that they aren't is counterintuitive (not wrong or illegal, just counterintutive)
And you clearly didn't read my comment, because I specially said a NUMBER A(not a DICE a)
I noticed it immediately. Not sure why he's so convinced that it's impossible to see the outcome beforehand; when I looked at "which dice I should choose" I immediately noticed each dice had a strict advantage over another, like rock paper scissors, except you're forced to obviously pick first and tell your opponent (so they'll always have the advantage). Totals never mattered.
Then again, it could be that I'm too used to games where counterpicks/triangle advantages are important, so that's more ingrained in my thinking than the transitive property.
Same
I think it bc u genus
It seemed pretty straight forward. I agree
Do you do podcasts? I would love to listen to your content while I’m driving.
Same vibes as
•Water beats Fire
•Fire beats Grass
•Grass beats Water
:O
People who play Pokémon: Grass, Fire, Water right? What's so confusing?
And exactly when people ask which is the best Pokémon.... It's not transitive. It entirely depends on what the opponent has and does.
@@DatShepTho Pokémon is often transitive. Stats often beat type match-ups. Each generation to date has had competitive meta choices that have been put in S tier and often been banned for tournament play because they are just considered strong against everything.
Granted, those S tier Pokémon change from one generation to the next, but the point still stands.
@@CrashSable it's not transitive though. There's no pokemon that outright beats every other pokemon in every situation. And if the transitive property did apply, there would have to be one
There will always be a Pokémon with some ability, ivs or moveset that beats a meta pokemon though. Otherwise it's probably banned to ubers
I often watch Vsauce videos and leave dumbfounded, entertained, and a bit smarter for the experience. This is the first video in a long time I understood why the "worst" was better than the "best" before the explanation; even with this being the first time I've heard of intransitive dice.
Decades of board game logic has finally paid off!
In this situation, the fact that you pick first actually hurts you, because no matter what you choose, your opponent can choose the better option. It's like playing Rock-Paper-Scissors when your opponent already knows what you're going to play.
It's about the individual match ups for each face against every face, you can have a dice that can win more individual of these match ups of face per face, but still have a lesser total value on all sides
Another term for this paradox: *Rock Paper Scissors Paradox*
He sounds like my cousin who always ends his sentences by “I’m not crazy right?”
This seems like a practical demonstration of the MMA Axiom "Styles make fights".
Almost immediately before Kevin went into any of the transitive stuff I said "this is just gerrymandering with fewer steps." It's not totally the same but it's the same part of my brain that made it make sense. And I think seeing this would improve comprehension in people who struggle to understand gerrymandering. Annoyingly though I can't put my finger on their exact mathematical connection, and I'm too old to furiously work it out like I'm back in calculus haha
This one really wasn't hard to grasp.
"By the transitive property A>D." ... this man has never watched NBA, NFL, or even a chess league..
Did you even watch the whole video?
@@system_ai9248 nah he didnt
I usually can't wrap my head around the paradox presented and feel very dumb, but this one was just obvious from the get go to me
It's like pokemon where fire beats grass/ grass beats water/ water beats fire
Yeah, either I'm getting wiser to these proposals, and/or this show's dumbing down.
It’s definitely the show. With the recent shorts and now this, the recent trend is mislead audience and then tell them what you said before was wrong.
At least the trend before this was introductory stats.
Seems lazyness to me.
@@traiton6653 A paradox woah omg the title

@REPORT BOTS ON YT!!! jeez chill it’s youtube
Soon we can celebrate when you hit 100!
It's just a loop and whoever goes first loses essentially. A>B>C>D>A....... and on and on and on not complicated to grasp at all.
Hey Kevin @Vsauce2 , I was thinking about a probability question the other day.
If I get the roll a dice only 6 times, except for when I roll the number 6, then I get an extra roll. How many times can I expect to throw the dice on average?
The answer is pretty surprising. Don't know if you've done a video on this before. But it's definitely be interesting.
Legendary Berkshire Hathaway investor Warren Buffett challenged Bill Gates to play a simple dice game, but Buffett had a set of Efron’s non-transitive dice. Gates was suspicious at being able to choose first, and after looking at the dice, he decided not to play. NOW YOU KNOW THAT.
Never trust dice games.
Second
Smort
But you didn't answer the most important question. How do I win?
vsauce: Right?
me: oh no not aga- “ok let’s play again”
me: *visible confusion*

Nice clip! Thx 🤯
02:38 "...then A has to be taller than C, right?" For a moment I expected a "WRONG!" there. That would have been mindblowing! 🤣

Kevin looking over at his team, asking if that joke went to far. xD
I was getting nervous, not seeing any mention in the comments xd
Everyone: oooooh makes sense
Oh
@REPORT BOTS ON YT!!! mpiym
this is like the elements in pokemon or other games. water beats fire but water cant beat grass type but fire beats the grass type
I view this as me having the weakest gear in a rpg game vs an extremely challenging boss and somehow winning.
Me, who has seen Numberphile's video about these dice:
Yeah, I know where this is going.
Also, no one is gonna talk about A vs C or B vs D!?
yeah the correct move would be to compare each combination of the dice choices to see the full picture, rather than making assumptions illustrated in the video
That's what I want to know.
It would be better if A vs C was a 50/50 odds like with B vs D, but it's a hard balance. Also if the video started out with the complicated dice first.
A strange game. The only winning move is not to play.
Or go second.
rock paper sciccors is exactly the same. just not with numbers.
its only fair because you have to choose at the same time.
but thats why initiative is not always the best, sometimes you wanna react because you know better.
If your opponent *also* chooses a random dice of the 3 left, the one who has the dice with the highest sum of numbers always wins.
I actually think it was easier to see 'why' with the first set of dice, although the same argument applies for the second set of dice.
Think about it this way.
A vs B:
When A rolls 4, it beats everything B can roll, which happens 4/6 times. 4/6 > 50%. Hence A > B
B vs. C:
When C rolls 2, it loses to B, which happens 4/6 times. 4/6 > 50%. Hence B > C
C vs. D:
If D rolls 1, C automatically wins. This happens 3/6 times = 50%. So 50% of the time, C already wins. Furthermore, D only beats C, when D rolls 5 and C rolls 2, which happens 3/6 * 4/6 = 1/3 of the time. Hence C > D
A vs. D:
If A rolls 0, D automatically wins. A can only win if A rolls 4 and D rolls 1. This happens 4/6 * 3/6 = 1/3 of the time. Hence D > A
