After much debate, the realm has decided dragon jousting may not be the best way to choose its leaders, and has begun transitioning to democracy. Your company was hired to survey the citizens of the land and predict which candidate will win. There’s a lot riding on this: if you get it wrong, heads- well, your head- will quite literally roll. Can you predict the winner? Dennis Shasha shows how.

First! Hello, TED-Ed!
Second! Hi Ted Ed! I love your videos! Especially riddle videos! Also, can you do a video on why people like certain pets more than others. Ex: Dogs>Cats>Fish
Hate you ted.
Hey what about for second one we do account Head for none and tail for either one the polls might give a bit close result not sure please justify
Hey, this one doesn't make sense.
If you're asking everyone to flip a coin, and always say "Troll" if it lands head, you're effectively not counting them at all because you don't even know if they support troll or tree.
Say out of 100, 55 actually support trolls and 45 actually support tree.
Now 50% of the population on random will get heads (always trolls). Let's suppose all who got heads actually preferred troll. You're result would still be 55 troll and 45 tree. Now you'll remove 50 trolls as 50% were forced troll. Your final result is 5 troll and 45 tree, a huge win for tree.
But in reality, troll is still the majority. You're getting skewed results because you nullified 50% of voters. That's bad.
This one doesn't make sense to me.
"Okay, so I want you to flip this coin twice. If you get two heads, say you support the troll. If you get--" (door slams)
A more accurate possibility
Ugh, been there (though in my case, it wasn't a door slam, it was a phone slam). ¬_¬

The correct answer is to
A: Ask the citizens to write down their choice anonymously
B: Come home
C: Count the results
D. Tell the eyebrow your results
E. Flee the country
F. Start your job somewhere else
Yeah, why didn't he just do that?
@Meow Cat ok, so why can’t do it? An anonymous poll?
@Meow Cat why they lie if it’s anonymous
@Meow Cat Wouldn't they lie in the poll presented by Ted as well? They could just as easily lie there too or change their minds afterwords
@Meow Cat do you even know what anonymous means

Plot twist: The dragon was actually hired by the troll to kill the tree and he knew that majority will vote for him in the next election as he's a better candidate than the dragon. The dragon didn't want to win, he was just helping his friend.
true
That's not a plot twist that's pretty close to actual campaign strategies
The spoiler effect is a thing. One example of this is in Australia where the Liberal party often doesn’t run candidates in Green or Labour areas to have them battle it out, making it easier for Liberals to get seats elsewhere. Sometimes one oft the two major parties will even find a way to financially support third parties as well

next time put the riddle against the troll in power.
Therapist: “Eyebrow of Sauron isn’t real, it can’t hurt you.”
Eyebrow of Sauron:
Just give those voters a little piece of paper and a pen, write down their favourite candidate secretly so that they don't feel ashamed, roll and put it into a box. Open the box at your home, count and translate it into a data. Repeat the polling process 5 times so the data can be closely accurate. Thank God your neck could easily be saved.
That's what the actual election will do, so what's the point?
@@Inkyminkyzizwoz point is the solution in this video is not so practical.
@@Inkyminkyzizwoz The actual election will do it with everyone, not just a few people. Also there's a concern that people wouldn't take the poll seriously since it doesn't elect anyone, but I don't see how that is a problem.
Wouldn't work because they aren't able to tell that you are 100% honest. You could count the number of votes in the box, take their vote, and recount it and know who they voted for. This added layer of protection doesn't add any layers of protection, so your solution may as well be you take their vote and say it's anonymous.

I mean, I know it's a riddle and not an actual polling strategy, but I feel like the real pragmatic solution would be to simply say "all respondents are 100% anonymous and there is no way to trace your answer back to you"
Makes much more sense than using coins, hoping that you don’t get the door slammed in your face and having to make presumptions about how many times they got heads. What makes them even think that they will flip the coin to begin with?
They use this method in real scientific studies where the subject has to interact with an experimenter, or for topics that are especially controversial, to give subjects another layer of protection
@@isabelhuang_1 We actually used this in my Compilers course too. A week before a project was due, the instructor told everyone to make their computer generate a random boolean, tell the truth if it was a 1, and answer "Yes" to whatever the next question was if it was a 0. The question was, "Have you not yet started the project?" and he said that it's great because if you really haven't started the project you can just say to your friends "My computer made me say it!" if you are embarrassed, and it's more accurate than asking the question outright in his experience (even if we all covered our eyes).
What would your response be to: "Prove it."/"I don't believe you."/"You expect me to believe that, despite me telling my vote to your face, you do not know what I voted?"?
Remember, you don't just need to convince them their vote cannot be identified by 3rd parties, you also need to convince them *you* cannot identify it.
ppl would still be embarrassed about having to say it directly to someone though

@@LuminixsGameGallery what was the auto correct?
I think the key condition that should have been mentioned is that polled people will be 100% honest on the result of their coin flip. Otherwise, everyone could have lied about flipping the coin and stated their real preference, and if you remove 50% of troll votes based on the assumption that they were all honest about the coin, you'd be very wrong.
"A giant orange troll and an experienced tree statesman"... I see what you did there lol

@@zonzaykay are you suggesting an assasination of Biden. I mean him falling up the stairs kinda looked like it, was just missing gunshot noises

For the second part, I think it would be more intuitive for the people (as they already answered your first poll) to flip the coin, and on tails tell you the truth, on heads a randomized answer, determined by a second coinflip.
The problem is though is that you don’t know which answers are the randomized answers and which answers are the real answers. So you wouldn’t be able to narrow down anything.
Say you decide to delete 50% of the answers to account for the randomized ones. You could very much be deleting the flips that told them to tell the truth, but you wouldn’t know it.
You need a way to be fully certain that you can remove answers that are statistically likely to be wrong, while being able to keep majority of the truthful responses.
@@Serennekin But you do know which answers...
you know that 50% of the time they'll get heads, meaning its a random answer. 50% of those answers will be for each candidate. Then just remove 25% from each parties total percentage of the vote to get the real ratio. Exact same as in the video.
that ends up having the exact same probability for everything
@@Serennekin doesn't matter, has same ratios
i just came up with telling the people to decide who’s heads and who’s tails and whichever it lands on is what they say. i think that’ll give them the opportunity to say who they actually support while they think you think it’s just what they flipped
For what I've read, no one is asking the real question here:
How did a snake (an armless, legless being) manage to win a jousting competition?
Also, who is it representing? The elven? The treefolk? The goblins?
Maybe there was a snake related coo
The tree represents the treefock troll for the goblins and dragons for the elves

@@user-vn7ce5ig1z well someone edited a picture of trump to make see what he'd look like without the tan-I mean natural skin and I don't know whether it's just because we're used to how he looks, but the picture looked worse.

Loved the LOTR references... All powerful eyebrow and incredibly gollum-like stranger going "what have you got in your pocket?) ;)
So this relies on perfect probability from the coin flips AND that everyone tells the truth about their coin flip. Seems preeeetty flimsy, especially if it was a close race.
It says in the conditions that everyone will tell the truth (its a logic problem not a pragmatic one), and if you repeat it enough times the law of large numbers dictates you'll be able to get the error from a perfect probability split small enough to predict the results with the required accuracy, especially if there is 10 points between the candidates as seen here
In pragmatic world you would ask them to go in the house and assign each side an candidate and ask them to vote for it and tell you the same.This will give them deniability bcs coin decided and thus they will tell thier true preference(if they really want us to live)
@@randomname285 Yeah you're right for the most part. I probably wouldnt have commented if they hadn't used a few hundred people as an example.
But we're using the coins. Which means you don't know how many of the people actually support the troll/dragon because they're coin could have flipped to tails or heads.
And the vid said everybody wants to help you.
So I don't see why this wouldn't work.
I wonder if it would be better to use the standard deviation to estimate a range instead of just the mean, and then use that range to determine a dominance of one of the candidates. That would at least eliminate the perfect coin flip probability.
I for once knew this one because they actually use this method in conservation when surveying things like bush hunting in rural communities.
Brutal! Absolutely brutal! In one ear and out the other.

The coin definitely helps with how you can accurately get an idea of what possible outcomes are available, at least mathematically. Getting to understand human emotions towards politics is a different beast entirely and always too complex. Love this illustration on both sides
I liked the markings on the coin......
"One Sssilver dollar"...awesome attention to a smlaa detail...
i’ve been wating so long for another riddle. i never get them right but there fun to watch 😃
i remember learning about the first half of this riddle in my statistics class in hs! it's a common technique, except participants will mark whether they got heads or tails on a sheet out of sight instead of leaving the percentages to chance
If you poll a large enough number of people, you don't need to know who flipped what - the results will be indistinguishable from an even 50/50.
That's why you flip the coin yourself.
@@maxastroPretty sure it isn't, or else every single video on CZcams would basically have the same amount of likes and dislikes (also rip dislikes).
@@RGC_animation It's not random chance whether someone likes or dislikes a video, though.
@@maxastro Oh you mean coin flipping, ok then.

3:14 uhhh what a constitution
Short answer: No.
Long Answer: Still no.
In the second part, 25% of total votes are due to coins being HH or TT, thus we subtract equal number of votes from both sides (25% of total).
If our opinion poll is x>y initially , then after subtracting equal number from both sides, it will still be x > y, thus making this extra step redundant.
We can directly say that 105 votes for troll beat 95 votes for dragon.
Very life changing, mudiji
So the Orange Troll is obvious, but is the Tree Bernie, and the Dragon Hillary?
The dragon would be Biden IMO
Something tells me that the dragon is Harris, takes over right after biden wins and is super unpopular immediately after... hope this comment ages well ;)

I never clicked faster than a ted ed video notification pop up about a riddle that i definitely can’t finish 😂
I can now die in peace. This important question in my life has at last been answered.
They are finally doing double riddles where you don't have to go to brilliant to see the answer to the second one
For the second, I’d have them flip 1 coin. If heads, they give their real answer. If tails, they flip again to give a predetermined answer. Same statistics, 1/4 fewer flips on average, easier for respondents to remember without 2x2 chart.
This single coin flip model (not the one I proposed above) is how they poll disgraceful questions about spousal abuse and other crimes.
My answer for the second riddle: Just tell them to say Troll for heads and Dragon for tails. But each time, say this sentence, "You know, this system is flawed. U flip the coin and I don't know if u got heads or tails. So u could say Troll and I'd never know if u actually like him or it's the coin" As much as I know people, most will tell their true preference. Ted Ed, the riddle was statistic, but otherwise, what do u think of this?
- This assumes that dragon and troll supporters are equally likely to lie about the dice roll.
- If the poll is meant to be 100 % random (they're supposed to tell the coin result), it's not really meant to predict voter support, they'd have little incentive to lie.
- Baselessly assuming that the supporters are equally likely to lie, you'd still have no idea about the result more than what side has the majority. 51 % said troll, does that imply that most lied and the election will be very close, or that very few lied and the troll will win almost every vote?
I have another answer: you tell them to lie for Tails, then you just have to give 50% of the votes for the dragon to the troll, and vice versa.
@@furyanakashi1159 Doesn't work. With 50 % lies you will always have a 50/50 result since every person is 50 % likely to answer troll (true or false) and 50 % likely to answer dragon. E.g. 100 % want dragon, you get a 50/50 result (since 50 % lie), and redistribute half of both sides, to 50/50 again.
If you make them flip twice and lie 25 % of times, you can calculate the actual result, but it's a much more complicated formula than the video's suggestion.
@@nilsjonsson4446 Yes you're right my bad ^^
Guys ur getting statistic. Think psychologically.
With Heads/Tails and Tails/Heads being the same result, wouldn’t it be 1/3 odds for the truth to be told by the voters?
LotR references:
1. Dormor - Mordor
2. The gray guy who asks what you have in your pocket - Gollum
3. One sssilver dollar - My preciousssssss
That's all I saw. Lmk if you saw something I didn't
For the second riddell.(p.s did not watch)
If you had everyone flip the coin twice
If its two heads they say the dragon
If its two tails they say the troll
If its a combination they tell you there opinion.
50% of the votes are acuret. We subtract 25% from each candidate.
Edit: can't believe i got ut right.
Did you come up with this after watching the first riddle? I did...
@@danielsahlberg4576 yes i did
Two riddles in one video? Thanks!
Finally season 2 of all those riddles.
I love ted ed riddles please make more
How could you subtract all the head results as you don’t know if they would have supported either candidate? There is the possibility that all the head flips supported the troll or tree fully, leading to a great margin of error.
Well, of course it could happen that most of the tree or troll supporters get heads, but with such a large number of asked people it's very unprobable. Looking at this probability-wise, a troll supporter and a tree supporter have the same probability of getting the heads, so the number of troll and tree supporters that get the heads will be similar as number of troll and tree supporters that get the tails - not necesarilly the same, but there shouldn't be any drastic differences. And the margin of error is acceptable as you don't have to be 100% accurate with your predictions. So that's why we can substract all head results
The Giant Orange Troll. I get what you did there. 😂😂.
It's surprising that I was reading about differential privacy and this riddle comes along. This method basically gives the candidates a plausible deniability that they were doing what the coin told them to do. Since we have no way of knowing the coin flips, he could give a fixed answer or honest answer. So the coin flips adds random noise to the distribution but since we know the expectation of coin flips we can remove this noise and get the correct result without violating the privacy of the candidate.
When I see the name "Dennis E Shasha " I immediately remember of Our potato girl
It's not everyday when TED-Ed makes a sequel riddle.
Also, plot twist: a wizard resurrects the treefellow and found out who killed them. What now?
the dragon dies because murder is not pog
They vote for dragon and they eject him
I came up with a different solution to the second part: everyone flips the coin twice. If they get two heads, they lie, otherwise they tell the truth. This makes 1/4 of both groups lie, so you could make a system of equations to determine exactly how many people actually support each side§, but the side with the majority of votes should say the same.
§ If T and D are the number of people who vote for each candidate, and T’ and D’ are the number who actually prefer each candidate:
T = .75T’ + .25D’
D = .75D’ + .25T’
3T = .75D’ + 2.25T’ (multiplying the first equation)
-(D = .75D’ + .25T’)
3T-D = 2T’
T’ = 1.5T -.5D
And the equation for D’ is analogous.
So to determine the number of people who actually prefer a candidate, multiple the number of votes for them by 1.5, and subtract half the number of people who didn’t vote for them.
That's a better solution, because larger fraction of population will present their accurate beliefs, leading to more accurate poll.
Of course, you could have them flip the coin even more times. If, for example, everyone would flip the coin 5 times, and lie on 5 heads, then 31/32 of the polled would say their actual preference.
You shouldn't overdo it, though. If you asked everyone to flip the coin 20 times, and lie on all heads, the odds of them lying is 1 in a million. That's not really plausible deniability.
@@jakistam1000 Well, given what you said about plausible deniability, that does make the video's suggestion better than mine.
With the video's solution, 25% of the total population is made to lie in favor of each side, so even if everyone who voted genuinely was in favor of one side, they'd still have good deniability (eg, if it was 25% forced troll, 25% forced dragon, and 50% true dragon, there's still only a 2/3 chance that someone who voted dragon said so genuinely), and in a more even vote, both sides have about a 50% chance.
With my option, however, 25% of both sides lie, so in an even race, any one person's vote has about a 75% chance of being sincere, making it less deniable. If the vote is less even, the minority gets more deniability, but only a little, and the majority's deniability gets even worse; getting to even the worst-case 67% of the other method for the minority requires an imbalance of at least a 40-60 split, while the best-case 50% requires a 25-75 split.
More riddles!
Only OG's remember the small lil' guy from the dragon jousting riddle
He is back
Lmao I’m not gonna ignore the prediction of the blue dragon wiping out of ‘the old tree man’. If anything happens to Joe, Ted Ed said it first lmao
I'M DYING FROM LAUGHTER JSKJKSJKSJKSJSJSJJS
Feels more like Bernie was the tree and Biden the dragon, then again the troll won
wow! this is so fun!
I don't get it. How can you subtract 50% when within those 100 people there can be legitimate troll voters?! 🤔🤔🤔
If the distribution is uniform, then it is feasible
But in the same time they could be tree voters. What this method is basically doing is saying: if you get heads, I’m not going to count your vote, but if you get tails you *have* to tell me your actual vote. This way, you guarantee that all your votes are real votes without anyone lying to skew your results. So you basically shifted the bias from troll voters to bias in the whole voting distribution
this is the only riddle where i actually figured out what you would have to do.
This is a very wonderful idea
The one real candidate it's a fire eye at the peak of mountain.
Yep ! The illuminati
This has a Monty Python reference in the title card yet TED-ed failed to include one in the last video, The Spanish Inquisition
Pretty unexpected, eh?
