You and nine other individuals have been captured by super-intelligent alien overlords. The aliens think humans look quite tasty, but their civilization forbids eating highly logical and cooperative beings. Unfortunately, they’re not sure whether you qualify, so they decide to give you all a test. Can you solve this hat riddle? Alex Gendler shows how.

Imagine actually coming up with this genius plan and spending the next 5 minutes carefully explaining it to everyone, just for the last person to screw up and cost everyone their lives.
imagine coming up with this plan and while explaining it you recognize the 2 guys that waited on the exit side of the revolving door at the mall.
Imagining everyone understanding the plan without starting a petty fight with someone for no reason
I've been in enough group projects to know it at least takes 1 hour to decide who's the 'leader' of the group, another 2 hours to come up with a plan, and there'd at least 2 people who did not listen at all
technically, if that happened, there would be a 50% chance of survival because the first guy had a 50% chance of saying his color.
@Zwei Stern No, he's right. If the last guy messed up, then your survival would depend on whether or not the first guy got his hat correct.

I just love how Ted creates a backstory and then goes into detail to make it as logical as possible. E.g the universal translator app

Yeah it is so good 😊😊.
It's similar to infographics
Yes
Ahhhh, the alien's voice at 1:26 is so cute!
“Quick, What do we do?!”
“No idea…”
This is the most ingenious riddle I have ever come across. It makes perfect sense, it's not confusing and the solution would clearly work, but I would never have figured it out, no matter how much I thought about it.
+++++++
if someone is going to kill you then you will be able to figure it out.
Except for the fact that it's not agaisnt the rules to take off your hat and look at it.
I have a easy answer. tell the tallest person to signal the second tallers persons hat color by, if the second tallest persons color was white, the tallest person would say white. and it goes all the way to shortest.
Alex Qwertyuiop but you can only have 1 wrong guess so your strategy wouldn't work

@Ashley Playz Data, duh
@Ashley Playz Look at the reply immediately above yours.
only one serious problem of this riddle : everyone must understand your plan
Well the alien says you have 5 minutes to discuss, so you and your friends can discuss and agree on that plan :)
That's why it's a test to see that the whole group is qualified or not.😂
@@eliasheinrich5617 so why won't the tallest person says all hats colours starting with the first guy?

Imagine everything is going as planned and the last person calculates his colour wrong and everyone dies
i think it would be like no more than 5 ppl and they get eaten xD (even with showing this video )

This can be extended to any amount of colors. Let's say we have three colors red, green and blue. First we assign a value to each red=0, green=1, blue=2. The person starting to guess a color adds up the color values of each hat he sees and takes it modulo 3. For example for a lineup of (r,g,g,r,b,g) the sum would be 1+1+0+2+1=5%3=2, so he says blue. The next one does a similar calculation 1+0+2+1=4%3=1 and subtracts this from what the last person has said, leading to 2-1=1=green and so on.
Interestingly, the riddle gets simpler if you use an infinite amount of colors. Again assigning values to them, and for simplicity just consider the values instead of colors. The person starting simply adds up all the values and says the corresponding color. Now the next person does the same and subtracts the result from what the last person said. So for a lineup of (12,2,43,29,1), the first one says 2+43+29+1=75, the second 75-(43+29+1)=2 and so on.
If you tried to make me do math like that under that kind of stress I'd just tell the aliens to fucken eat me!
I'm not sure it's working, it's not enough to subtract the sum I see from what the last one said.. example: 0,1,2,1 - the first says 1+2+1=4%3=1. The second sees 2+1=3%3=0 so he says 1-0=1 (good), the next one sees 1 so he says 1-1=0 - wrong!
I believe the correct solution is to set a bit: in the first turn it's what the first person says (i.e., (total sum)%3) and then on each turn, the bit is set to: (what the one before last said) minus (what the last person said)
So in the above example, the first one says 1, the second has bit=1 and sees 0 so he says 1-0=1. the next one has bit=1-1=0, and sees 1 so he says (0-1)%3=2, the next person has bit (0-2)%3=1 and sees 0 so he says 1-0=1
How do we know red is not eight and purple is ten

Realistically, the aliens would've also said that they aren't allowed to touch their hats, or otherwise remove them from theirs or each others' heads, to prevent them from just looking at their hats or switching them around.
That doesn’t change anything at all
Realistically this would never happen
@randomdoggo9489You could simply look at your own hat and guess that color correctly, or swap your hat with somebody else’s without moving to look at them, and now you both have hats with colors that you know

+Uber Megustador Si aici te vad :)) ? Still doesn't sound easy to me. :D
Is not correct just saying the color of the hat of the person in front you and the memorize all?
Juan Felipe Martínez No because you have to say the color of your own hat corectly and that may differ from the one in front of you.
+Juan Felipe Martínez What? !!
That's really clever. Too bad you'd never be able to get 9 average humans to understand the strategy in under 5 minutes.
What comments are you talking about? Most people who figured it out probably paused it to think about it for a while, so it took more than 5 minutes. And if 9 people out of 8 million viewers instantly grasped the solution, that doesn't mean it would be realistic for a random group of 9 people to figure it out (worse odds than winning the lottery). Not to mention, a handful of people out of 8 million would be above average by definition.
nah they don't all have to figure it out for themselves, it just has to be explained to them...like how it has been explained to us, in this five minute video :)
XD
well it took him 4 to do this so i am a pretty average person,... im not smart.... but i got it so i think it would work
That takes a really good lecturer, a marker pen, and a white board.

my comp-sci teacher used to give us this problem when we started the logic module. it takes surprisingly long for a group of 12 year olds to figure out a solution for this.
I never found the answer to this riddle by myself lmao, not even when I was 12
My Answer, before the answer is shown is that the person in the back (who guesses first) takes a while to give his answer if the person in front of him has a black hat. If the hat is white, he says his answer quickly.
The next person down the line then knows if his hat is black or white, (lets say its white). So now he will take a while to give his answer, still saying (white) if the person in front of him is wearing a black hat, or quickly if he is wearing a white hat.
Welp the answer works too... i guess mine was a bit more simple.
Nope, it says you can't use vocal systems to win or else you're all eaten....
+Roy is a weirdo that's like saying time is of no essence here. Everyone will speak their choice at a different rate, give the code enough time to buffer for someone to choose their choice and it should be no problem. everyone will know their answer quickly and it takes less brain work to do this, so this should be less of an issue than the counting the hats method.
Pretty good idea
I thought of the same thing too
Step 1: confirm you have green eyes.
Step 2: ask the aliens to leave

@@alexzander7629 Yeah, no; they're right. Cooperation is cooperation in whatever form. The scenario of "which type of cooperation counts" is convoluted nonsense, making their edict against who they will and won't eat just silly.
That also makes me think of something else, why couldn't the aliens try and talk with people with the translator? They wouldn't need the arbitrary test and would get food from us they may like. These aliens are not very co-operative.
They didn't say cooperative, they said cooperative and logical. Clearly, the average human does not meet their minimum standards for intelligence, based on this goddamn riddle.

Actually, that's true. They dont know if humans can be logical and cooperative, how would they know they dont have telepathy or are inmune to lasers or stuff like that?
Also another way to solve this is to take your hat and look at it. It's not looking behind, it's not giving a signal, it's not stepping out of the line. There's no infraction here
Max Power they never said you couldn’t take your hat off and look at it
Well, I hope I’m the tallest if this ever happens to me
I am the tallest
Yeah, but...
What if your team doesnt pick up the hint?
@@carolinacortesmartinez4305 yes
@@carolinacortesmartinez4305 the challenge starts off with 5 minutes to discuss, so you would be able to tell them what to do. No matter how tall you are, as long as you can communicate the plan, you win.
Yeah, me too.
By the thumbnail I thought you had to figure out why which one had which colored hat, after a good five minutes of stareing at it, ITS IN THE NOSE

I would switch my hat with the one in front of me and said - "well, I guess my hat is white now." The fact that the person in front of me let me take of her hat proves also that we are cooperative.
would she let you take her hat though?
@@CheeseTheWhistle because if everybody does this, everybody will guess correctly except the last guy who has a 50/50, but that doesn't matter anyways
Honestly a much simpler plan
“Hats off” to who ever solved this riddle!

Ok I’ll leave sorry.

Plot twist: They’re all the same height.
I think in a real scenario like this, there'd be people that just refuse to cooperate. Rather than talk logically, there'd be a frenzy of crying, arguing, or just people refusing to play along because of stubbornness, and "why does this have to happen to me?" kind of thinking. There's no selflessness, nor calmness, nor logic in the average person's way of thinking. Likely, they'd all die because the actual smart people in the group who would have thought of a solution would actually be too busy trying to calm the people freaking out, and trying to get the stubborn, defensive people to cooperate. And so everyone would die. This is why I'd rather take my chances in a single-person challenge than have to deal with other people in a scenario like this.
+SirSaxamaphone Not saying this isn't a neat puzzle. I enjoyed this. I'm just saying it's more likely to be paired with non-cooperative morons who refuse to understand and choose to panic, than actual logical thinkers.
+SirSaxamaphone well sure, it said that at least 9 people have to get the correct answer. The more people who have to cooperate and get the right answer, the worse the situation is. What if they said that only 1 person has to get it right? Then of course you'd want as many people as possible. So, it depends on what kind of question is being asked or what the challenge is. But you're right that people would sometimes rather be stubborn and destroy all life rather than cooperate. That might be what happens in real life eventually.
+SirSaxamaphone Agreed.
+SirSaxamaphone you just described exactly what i think of the human race
+betatalk357 When he said single person challenge, i don't think he specifically meant this one. Obviously this is a biased challenge in the way that it CAN be logically won with 2 or more people (assuming you still get 1 chance to be wrong about a hat color like in the video). Obviously if they asked just one person to guess the color of their hat it literally would be a guess, with no prior information, or ability to deduce the color via logic.
The main point SirSaxamaphone was trying to make is the fact that this situation wouldn't even happen, because once the 5 minute timer started ticking half of the randomly selected people would be freaking out. Crying about why they're here, why me, etc. Ever watched the SAW movies? It would basically be like that. And if even ONE person cannot follow this logic to make the plan work, you're all eaten (unless they get a lucky guess). Even worse if the tallest is one freaking out since the entirety of every ones guesses hinge on that information.
That makes perfect sense to me.
But if you put me with 9 random people I highly doubt their ability to understand the concept and so we'll probably all die anyways.
Well, you were given five minutes to discuss it so I think you'd live :)
+babyy.tylerr twentyonephanicatthediscos Yes, but under pressure people are more likely to mess up--especially if they aren't familiar with thinking in this way.
I think 10 random people could do this, but not with only 5 minutes to solve AND learn/teach...
You are a hopeful person lol. Most people don't even pay attention to simple things in life let alone to a plan that may be way over their head. 9 people might be too many..
+TheFD Yep, there would be someone who would be stubborn and call the person who proposed the idea a stupid idiot XD
3:09 silly aliens, the purple one looked back and they didn't notice it
Why has no one commented on this comment
Good point
I was gonna say that
This is fuging genius
I don't think aliens would be that faithful to humans, as we humans are not faithful to one another.
superintelligent? they know the consequences
Funki Aww. ☹️You went there.
It's also sad to think, if we humans find any kind of supernatural or extraterrestrial life, instead of trying to reason and understand it, we will try to capture and dissect them. :(
true..true
Preach!
I figured out a different strategy and it only took me about a minute, kind of hard to explain and the execution would be a bit tricky but the first person would say the color of the next persons hat. The second person would either repeat that color immediately or wait 20 seconds and then say that color depending on the color of the third persons hat. If the third persons hat was the same color he would repeat it immediately, if it was a different color he would wait twenty seconds to signify that the next persons hat was a different color, and so on.
that's brilliant!!!
Brilliant
That’s exactly what I came up with when I paused the video. Don’t think this breaks any of the rules. Glad I looked for a similar comment :)
@RedDemoon but the solution given in the video is an indication
@RedDemoon if ANY type of indication wasn’t allowed it would be impossible. The truck is to find an indicator that doesn’t seem like it’s an indicator. Waiting a bit before speaking could just be chalked up to nerves or thinking about your answer
For the guy in back to see anyone's hat other than the person in front of them, the height difference would have to be massive... all the way down the line. Like it would need to be almost straight down slope from back guy to front guy.
Nah man, I got it... the 10 feet tall guy is in the back and then just minus a foot for every person next in line
I was thinking the same thing - so I'll pretend that's the reason I didn't manage to solve the riddle ;)
They could get put on a stand of some sort, so the one at the back is guaranteed to be the tallest by a large margin.
the rules is that u can step out of the line but moving ur head to the side to see from that angel is possible
Yea you're being logical, the aliens can't eat you
This was the riddle that led me to discover Ted-ed
This is great and I love the logic, but show me a random collection of 8 people on earth who I could convey this strategy to and have them understand it well enough, in only 5 minutes, to then implement it in a life and death scenario. I'd say we're getting eaten.
10, not 8.
+arbootieoaks and ten minutes to preapare not 5
+Max Lipiec in the vid the aliens said they have 5 minutes
+Matt Figueroa to come up with a plan
+arbootieoaks this video lasts less than five minutes, and you can explain it way faster and in a most efficient way (for example if you first explain that hearing what's behind you + seeing whats in front of you is equivalent as seeing everything). Therefore its just a matter of remembering if the count is odd or even... I'm sure that if one out of the ten people knows the answer, everyone can be saved. Since this riddle is very famous you would be very unlucky to pick 10 people that don't know it :p
If my classmates did this,they would all die in no more than quarter a second

sharkgamer135 Your right! Hopefully their all British....
+Owen Meschter *you're *they're
It took me years of rewatching the video to understand why this worked
In real life, if you were to figure this out, you would probably have a higher IQ than the aliens.
Well technically, the aliens devised the riddle so that they can know if the humans are actually "highly logical and cooperative beings," which means that they themselves know that this can be solved by "highly logical and cooperative beings."
