the problem i have with this set of intransitive dice is that purple beats green 5/9 times, so against a random die, purple is the best and green is the worst

[@carykh]

Oh yeah, that is true that the purple die beats the green one 5/9 times! I'm not sure if there's a clean way to make all "opposite dice" come out exactly equal unless you give them a lot more sides. Wait! I just got a *weird* solution. If all the dice are D12s (dodecahedrons), you could have: Red: 12 threes Blue: 6 fives, 6 ones Green: 8 fours, 4 zeros (these three are essentially the same) Purple: 9 twos, 3 sixes. (purple now has proportionally more twos.) In this instance, purple and green are exactly tied against each other. (In order for green to win, green must roll a four (8/12) and purple must roll a two (9/12), which multiply to 1/2). Red and blue are also tied. However, the odds of blue-purple and purple-red are changed - so you win some, you lose some?

[@mjohnson2807]

@@carykh Wait @8:25 it shows purple vs green being 2/3. But mathematically it isn't that? Is that a issue with arranging the order of the numbers in the chart?

[@dsgowo]

@@carykh I think I've just proved that a perfect set of 4 non-transitive dice with the numbers we have (0-4, 1-5, 2-6, 3-3) isn't possible with any number of faces, but I'm going to double check.

[@dsgowo]

@@carykh Yup, here's the proof: The probability of green beating red is just the probability of green rolling a 4, which we'll call p. The probability of red beating purple is just the probability of purple rolling a 2, which must also be p if the set is perfect. I'll abbreviate these as P(g4) = p and P(p2) = p. Then, P(g0) and P(p6) must be 1-p. The probability of purple beating green is P(p6) + P(p2)*P(g0), and we want this to equal 1/2. Plugging in, we get the equation: 1-p + p(1-p) = 1/2, which becomes 1 - p^2 = 1/2. This means that p must be 1/sqrt2. But this is a problem because p is now irrational, so no die with finite sides can have probability p of rolling something. Therefore, no perfect set of 4 dice with these numbers is possible, regardless of the number of faces.

6:20 The second you explained this, I thought about gerrymandering. Creating matchups where one side is having its "potential" deliberately wasted to skew the results of what would have otherwise been an overall more proportional result.

[@ncedwards1234]

Non-transitive dice and voting is indeed the math behind gerrymandering. It also explains why swing states are emphasized so much in presidential elections, because a marginal win is still the same as a landslide victory in 48 states + DC (because electoral college). So if a politician is limited in the people they can sway with their campaign, they want to target people who are 1) On the fence (could vote either way, but you get one vote rather than 60% vote for one candidate and 40% for another). 2) In a swing state that can change the electoral college vote (because >50% = 100%). It's like an avalanche where you could be the changed vote that changes your state, therefore the president, BUT it's planned out so that you're less likely to be in this situation unless prior politicians wanted people in your area to have this power. Otherwise it goes like you said, you're moved to an area where your vote cannot make a difference. Or you criminally charge people for bogus crimes like drug possession to disenfranchise groups like the poor and minorities. Through this the process of politicians weighting votes unevenly, they are indirectly biasing votes for future politicians (such as themselves and their cronies). I sure hope they don't attempt to remain in power against the desire of the average voter's desire. 🤔 Then we can get into propaganda because some of us are swayed to another side with less effort, so we will be targeted more than the stubborn ones who need only the occasional reminder to keep voting the way their parents taught them to (because their grandparents taught their parents how to think). New customers cost more than maintaining old ones, so allocate resources carefully in a zero-sum game. And remember, lies are cheaper than truths; and winner takes all because the past winners said that's how it should be.

[@cogwheel42]

Yeah 1 minute in and I went searching the comments to make sure gerrymandering came up :)

Very good morale at the end there. It's REALLY easy to fall into the trap of assuming that everything is transitive. We treat most things in life as transitive, because it's easier to think about things that way. IQ scores, test scores, income, net worth, and subscriber counts are treated as transitive by society. But when you look a little deeper, we find that there are many different kinds of intelligence that excel in different ways, earning money is a different skill than spending money efficiently, and the size of a fanbase is usually inversely proportional to the social experience it offers.

[@BlazeMakesGames]

I find it interesting that in the final one if you compare all 4, the blue and purple die win 12 times each, and the other two win 6 times each. Which makes me curious if you can create a set of dice that has this property but if you roll them all simultaneously, they have an equal chance of winning. 36 is divisible by 4, tho something about each die winning 9 times out of 36 feels off. So I imagine it might be easier to pull off with 3 dice each winning 12/36 times or 6 dice winning 6 out of 36 times.

The thing about chance is that it can go any way, so if you just make "A has a 20% margin over B" "A beats B", luck can roll you around. And if you flip a coin 63 times, the chances of you getting 63 heads is the same as you getting 27 heads. For a normal person, 27 to 36 isn't that surprising. But maybe, just maybe, there's that hardcore carykh fan begging to get a 27/63.

[@Shatterverse]

What's more useful is combining two dice together. Anyway stuff like this is not entirely dissimilar than when you use symbol game dice. Example sides: 1 loss, 2 defend, 3 attack - alternately 0, A, A, B, B, B. Then change it to 0, A, AA, B, B, BB to make things more interesting.
