RICKY GERVAIS SHOW - HOW TO GET TO HEAVEN

A different version of a classic exercise in logic. Another, more difficult version of this well-known brain teaser goes like this: "Two guards are standing in front of two doors, identical except one door has #1 on it, the other #2. One leads to Heaven and the other to Hell, the guards know which is which, but you don't. One guard always lies, and the other always tells the truth, but you don't know which does what. You can only ask one of them one question in order to find out which door leads to Heaven - and the guards have no knowledge of the world around them, except which door leads to heaven and which leads to hell, and whether the other guard lies or tells the truth. So the guards can't answer any questions like 'How many heads do you have?' or the like, although, in this scenario, those questions would be useless anyway because you don't know which door the liar and truth-teller is guarding. So what question would you ask?"
The answer is: "What would the other guard say if I asked him which door leads to Heaven--door #1 or door #2?."
Assuming door # 2 leads to Heaven, if you ask the liar, he will say "the other guard will say door #1". If you ask the truthful guard, who knows the other guard always lies, he will say "the other guard will say door #1". You then know, through logical deduction, that door #2 actually leads to Heaven. It makes no difference which doors the liar and the truth-teller are guarding. It works the same either way. The important element is that the guards are talking about the nature of the doors themselves, not the nature of the doors they're guarding.
But Ricky stipulates at the start that the liar is guarding the door to Hell, and the truth-teller guards the door to Heaven. The way Ricky frames the "right" question - "What would the other guard say if I asked him which door he was guarding?" - would result in one guard answering "Hell", and the other "Heaven"-- the liar standing in front of the door to Hell would lie and say "the other guard would say he is guarding the door to Hell', while the truthful guard in front of the door to Heaven, knowing the other would lie, would tell the truth and say "the other guard would say he is guarding the door to Heaven". You would then logically assume that the guard who said "The other guard would say "Heaven" was standing in front of the door to Heaven, and the one who said "The other guard would say "Hell" is actually guarding Hell.
But I don't think any of them, including Ricky, realize that a much simpler way to solve Ricky's version of the puzzle is to ask either of the guards if they're standing on their heads.

In the original podcasts I seem to remember Ricky saying the next week that he'd mucked it up and that you're not meant to know which guards which

[@happysquidNET]

Easiest question: "Are you guarding a door?"

[@RandomIdiotGS]

What? To solve the original problem? No, just no. Ricky Gervais told the conundrum wrong, but that is no excuse to join the fallacy in his explanation. It is never stated that the liar is guarding the bad door/path and that the honest one guards the true door/path. Asking if they are guarding a door just means you figure out which is the liar and which is honest, but that says nothing about what door or path is actually correct. Yet you then waste your one question. And if you ask "Are you guarding the door of truth/correct path?", both will answer you with "YES" and you learn nothing. You are Karl Pilkington.

[@JayOFae]

You're right that Ricky told the riddle wrong, but that's really not happysquidNET's problem. He heard a riddle from Ricky and solved it correctly.

[@danielpriest1142]

The thing is if I said 2+2=5 for instance. That wouldn't make me a liar, it would just make me really shit at maths.

[@NoNameC68]

Ricky fucked up. The liar does not always guard the door to hell and the truth teller does not always guard the door to heaven. Otherwise you can simply ask "How many doors are there?"

[@dhvsheabdh]

Or any question to which the truth is obvious.

[@kathyh4610]

NoNameC68 I would have held up and pointed to my hand and asked what it is.

[@skeetorkiftwon]

Kathy H Yeah? So you used your one question to know which one tells the truth, now you can't find out which door is the good one. The question has to be compound and ambiguous. Asking the liar which door the truth teller would send you through produces the hell door because the onus has been passed from you to the guard. Asking the truth teller which door the liar would send you through produces the hell door. In your selection, you negate the negative produced in the question. If you believe either of them, you die.

[@andyapricot4104]

Yes but in this video Ricky states that in this scenario the door to Heaven is always guarded by the one that tells the truth which is why the original comment is pointing out that flaw in Ricky's question.

This question was told on a radio program many years ago in Hong Kong, like 1993, and I remember my classmate took it to the class. My maths teacher love it so much and decide to let us play this for the whole class and no maths teaching. And, I'm happy to say I was the first one to crack down this question. My teacher only got it after I explained three times, and many classmates never understood.

[@dylanmedias]

Ok, so. Ricky tells us specifically that the one guarding hell ALWAYS tells a lie. And the one guarding heaven ALWAYS tells the truth. So you know that. You don't know what door is what, or which door the one who lies stands in front of. But if you ask any question like "what colour are your eyes" or "what colour is your hair", or "what is 5x5". The both of the guards are identical. So by asking one "what colour is your hair". So let's presume those two IDENTICAL guards have brown eyes. You would gather that it was heaven or hell based on their answers. If you asked heaven the question, he would tell the truth and say that his eyes were brown. So you would know that he had told the truth. But if you asked devil, he would have to lie as no matter what you ask, he will ALWAYS lie. So he would have to lie by saying a colour that wasn't his eye colour. Therefore you would know that he is lying and that is hell. Surprised Ricky didn't think of this. Think about it and tell me ur thoughts

[@JamesBongo]

I thought it's seemed too simple

[@vantheman12welshman66]

[@howiseeit5326]

Dylan Fraser eaxactly what I was thinking there numerous ways around this

[@JUnderfist]

No no, In the original riddle and in this one you don’t know who’s guarding which door. So if you ask “Satan” what colour his hair is and he said blue despite the fact you know his hair isn’t blue thus helping you realise he’s the lier, you still don’t know which door he’s in front of. The legitimate only question you can ask is “which door would the other person say he’s guarding” because then you see who the lier is and which door is which.

[@_Stromboli_]

Right Ricky told the riddle wrong. One of the guards will tell the truth and the other will tell a lie but they can be guarding either heaven or hell the one telling the truth could be guarding hell and the one telling the lie could be guarding heaven. You don't know which door their guarding. So when you give the question whatever the guard says is the door they are guarding.

[@pgl0897]

Spot on.

[@debaser1042]

What? How does that work? Which question? Asking what the other guard would say? Edit: I get it now. If you ask either one of them "which door will the other guard say is the door to hell" they will always respond with the door to heaven. This is because the liar knows the truth teller would give you the real door to hell, so he must point to the other door since he must lie. The one speaking the truth knows the other guard is a liar, so he knows that the other guard is going to tell you that the real door to heaven is for hell.

[@debaser1042]

Jacob O'C It is fixed for the precise reason you brought up in your first comment. The guard telling the truth KNOWS the other guard is a liar. This isn’t explicitly stated but it’s implied by the fact that the guard telling the truth can ONLY tell the truth. And that the guard telling a lie can ONLY tell a lie. If they didn’t know what the other guard was going to say neither of these things would be true. You can’t always tell the truth unless you know everything there is. The same goes for lying. You can’t lie about what someone’s going to say unless you know that person always tell the truth. The implication of them always lying or always telling the truth is that they are ethereal beings that have a complete knowledge of the world. So in your own example where the liar is guarding Heaven, the door to heaven is still going to be the one BOTH GUARDS dictate as “Hell.” For example: If you ask the truthful guard who is guarding the door to hell, “what door is the other guard going to say he’s guarding?” The truthful guard will tell you that the liar guarding heaven will SAY that he is guarding Hell. He knows this because he can only tell the truth. It implies a limitless understanding.

[@debaser1042]

Jacob O'C Lol this is an old comment. One of my own comments distorted the answer to the riddle as well. I hope I can clarify what I believe to be the whole answer. The complete answer to the riddle is: Ask either of the two guards “which door is the other guard going to say is the door to hell?” You do not have to know which guard is guarding either door. Here’s how it works: By asking a guard what the other guard will say, you are guaranteed that the response will be a lie. Since you know it’s going to be a lie, asking the question: “which door will the other guard say is the door to hell?” Both guards will have to point to the door to heaven. The guard who tells the truth will tell you that the liar is going to call the door to heaven the door to hell. So he points you to Door A. Or The guard who lies is going to lie about which door the other guard would say is actually hell. Which means he’s going to point to the door to heaven, which is still Door A. We know from there that since Door A is the door to heaven, Door B must be the real door to hell. If you ask instead “what door will the other guard say is the door to heaven?” The guards would instead point to Door B. Once again, the key is to get the liar involved in a specific question. This is because he will always corrupt the response. In the same way that 1 x - 1 = -1 and -1 x 1 = -1. The liar’s participation will always give the opposite of what you asked.

[@majorcatastrophe2829]

Yes, originally it was a crossroads with two people, one from the liar tribe etc...interestingly the logical solution has something to do with "i"; the square root of minus one. Sorry, read above comment after commenting!

[@norituk9824]

In his own inimitable way Karl is an absolute genius. Ricky is right to say he's the funniest man alive.

[@mitchelldwight791]

THIS IS HOW ITS SOLVED, if asked "what door will the other guard tell me he is guarding?" to the guard of hell he will reply "he'll tell you he's guarding hell" which is a lie as the guard of heaven would actually tell you he's guarding heaven if you ask the guard guarding heaven "what door will the other guard tell me he is guarding?" the guard of heaven will say " he will tell you he is guarding heaven" which is the truth as the guard of hell would lie and say he is guarding heaven.. RICKY GOT IT RIGHT BUT EXPLAINED IT VERY POORLY ALSO THE GUARDS ONLY KNOW ABOUT EACH OTHER AND THE DOORS. WHICH RICKY DOESN'T MENTION. so saying like "how many eyes do i have" or "are you guarding a door" is not allowed and takes away from the whole logical exercise.

[@andyboreland]

You could equally ask, "Is it true that one of you two will lie lie to me?"

[@RandomRowan13]

Andrew Boreland You can only ask them one question remember. And even after you discover which when is lying you still won't know which door they are guarding.

[@andyboreland]

RandomRowan13 No, if I'm not mistaken, I could ask just one of them 'Is it true that one of you two will lie to me?' I will instantly find out. The devil will deny it, whereas the angel would say, 'Yeah, it's him'. Then again, the devil could tell a half-truth and say 'Yes, someone will lie' (telling the truth), then lie by saying 'It's the other guy!'. It's not exactly clear if the devil lies everytime. If so you could ask him any question which you already knew the answer to, Eg. 'Was my father's name 'John'?' Lost now.

[@RandomRowan13]

Andrew Boreland Keep in mind that Ricky explained this riddle wrong, the original riddle doesn't say the liar is always hell.

[@johnhall9885]

Ricky explains the question totally wrong here. That's why it's hard to understand and everyone on here is arguing. The question Karl is to ask is supposed to be about the doors and how he can work out which is heaven and which is hell. Devil will lie. God will tell truth. So to solve the puzzle Karl is supposed to ask one of them what door the other one would tell him to enter. Then all he has to do is enter the opposite door to the answer he is given then he is in heaven. Simple.

[@elliotyamamoto38]

You don't know whether it's the liar or the truth teller guarding the Heaven door. The questions you ask is - If I asked the other guard to point to Heaven, which door would he point towards? You then go to the opposite of whatever he points to. No matter who's guarding what door, they will always point to hell.

I was watchin something the other night where these dudes were trying to get in through doors by a similar situation but they werent allowed to ask about anything but the door. This one dude tried saying "what color are my pants" and "what is 1+1" but then they ripped his face off. I didnt get to finish watchin and i didnt know what the show/movie was, I was just flipping channels to see how they got in so Im very confused to how this works. would someone please explain this to me? I really don't understand sadly.

[@FilipH86]

This example is done poorly, cause here you can just ask what's 1+1, because you know that "god" is guarding the door you want to get to. and the "devil" is guarding the bad door, so here you can get the awnser simply by figuring out whitch guard is whitch. However there is another one that much more difficult (something about 2 jailors and 1 door = freedom the other door = prison) and in that example you cannot deduce the awnser simply by figuring out the guards, since there is no (Good or Bad guards) just good or bad doors.

[@BigR.O.B.]

isn't the right answer to ask what the other guy would say is the right door, and then go through the other door?

[@Vandalle.]

Ask what the other one would say they were guarding, and whatever the answer is, is the door that they themselves are guarding, the liar would lie and say the wrong answer which means he'd have to be stood in front of that one, the honest one would know that the liar would lie and say the opposite too, so he would have to be in front of that one. e.g If the liar is guarding door A he would say the truthful one would say door A, The truthful one guarding door B would know that the other would lie about guarding door A and instead say B.

[@denny1190]

I don't think you understand. It doesn't matter if they look they same, the question is how you solve it. If the devil looked like the devil I wouldn't need to ask the quest in the first place.

[@denny1190]

Ok I'll explain it again for you. we'll pretend your the one standing at the gates to make this easy. You would ask "Is my name Rose?" to either one of them. If it was the devil who can only lie he could only say "No, your name is not Rose." because he can only lie. He can't say "Yes your name is Rose." because he can only lie. If you got a God and not the devil his only response could be "Yes, your name is Rose." because he can only tell the truth. So no need for a second question no matter what. If you don't understand after this I give up or take it your a weird troll. Just think about it for a second.

[@denny1190]

My answer was based on if the devil could ONLY lie, if he was allowed to tell the truth too it would never work. I think Ricky said he could only lie but its been a while since I watch the video. I might look up the other version of it some time.

Let’s say you go to the devil and you say to him “if I was to ask the angel which door leads to heaven what would he say?” And the devil would point to his own door because he’s lying. So you would choose the opposite now. Now, if you said to the angel “ if I were to ask the devil which door leads to heaven what would he say?” And the angel would point to the devils door aswell because he knows that the devil lies. So they would both be pointing at the devils door so you have to choose the opposite.

[@zada4a]

I have an alternative solution which is using the assumption that the angel would be happy and devil unhappy if you choose heaven door and vice versa. (Read description for actual problem, not solving the one Ricky said) The question is simple: Would you be happy if I pick door #1 If the door is heaven and you ask the good guy, he would say: Yes and not be lying. If the door is heaven and you ask the bad guy, he would say: Yes and be lying. In both cases they say Yes if you chose to ask about the correct door. If the door is hell and you ask the good guy, he would say: No and not be lying. If the door is hell and you ask the bad guy he would say: No and be lying. In both cases they both say No if you chose to ask about the wrong door and Yes if you asked about the right door. Solved, given the initial assumption, which is not that unlikely and not such a big stretch!

[@Moerakski]

Ask this. Are you guarding this door? eazy

[@Capelett]

Pretty good.

[@pzdizzle]

Yeah but you dont know what the liar is guarding nor what the truth teller is garuding

[@KenDonMusicYT]

First question that came to me was "can you see me?"

[@manimezzi1935]

"Are you standing behind a door?" BOOOOM !!!!

[@koldtoftkim]

Simplified explanation Let's say door A is hell (the liar) And door B is heaven (the truth teller) 1) If you ask door A (liar / hell), what would the other guard say if I had asked him what door he is guarding. Guard A would say, hell. (which would be a lie since door B tells the truth and would say "heaven" if you asked him what door he is guarding) So if the guard you ask answers "hell" you know hell is behind the guy you just asked. If you ask door B (truth teller / heaven) , what would the other guard would say if I had asked what door he is guarding. Guard B would say, heaven, (which would be the truth, since door B is Hell, but the guard would lie and say heaven) So if the guard you ask answers "heaven" you know heaven is behind the guy you just asked. To this "what would the other guy answer" question, the liar will always answer "hell" and the truth teller will always answer "heaven". This happens because both the liar and the truth teller would in fact answer "heaven". but the liar is lying, so when you twist the question, the liar know answer hell. This way of asking, forces the answer "Hell" out of the liar. However the truth tell can never say hell, since he know that the other guard would lie and say heaven. Having said that, if there are no restrictions (which there normally is) you can just ask any question that you know the true answer to. Is 2 + 2 = 5, are my pants green and so on. But I think there must be some restriction to what you can ask about or something, or this is kind of an easy riddle. At least I know that "is 2 + 2 = 5" came to my mind in about 3 seconds.

[@tykykable]

"What colour is your hair?" Could literally ask anything.

[@codyb2082]

Thought the same, like asking what my name is

[@JacOfAllTrades.]

Well in ricky’s interpretation, that would work, but what he didn’t explain that it’s also unknown if the guards are in their respective positions, the honest guard could be in front of the door to hell for all you know, meaning that you can now rule out who the liar is, but you blew your only question on either guard and you still have no read on what door leads where.

[@BruceLeedar]

The more useful version of this problem is when they aren't guarding specific doors, but are directing the questioner to their preferred door (truthsayer->heaven, liar->hell). That way trivially determining if one is a liar doesn't resolve the problem.

[@zedooncadhz]

Well yes it would because you would allow yourself to be directed to the truthful guard's preferred door lol

I would just ask the guard "do you and the other guard look identical?" and if they say yes then it's heaven if they say no it's hell. Ricky's question both would answer the other guy is guarding hell

[@nickprezzo]

"If I asked the other one 'what door are you guarding' what would they say?". If you asked the angel, they'd say the other guy would say heaven because he's going to lie and say heaven (when he's guarding hell). If you asked the demon he'd say hell because the other guy would tell the truth and say he's guarding heaven which he is. Ricky got it wrong though, you're not supposed to know which one will tell the truth and which one will lie so that question isn't supposed to work. There isn't a loop that gives 100% chance of you going to heaven in the actual question (other than the only answer of course)

[@TheBrokenCircuit]

Simple, ask "If i were here yesterday, which door would you say is correct?" Truth teller would point to the correct door Liar would point to the correct door too as he would lie about actually pointing to the wrong door if he were here yesterday.

[@josephtheosworthmachael2052]

[@TheBrokenCircuit]

Dreqo Machael they will both point to the good door doesn't matter which one that you ask for.

[@JKOROX]

+Dinesh Kishore Both would just say my door leads to heaven (assuming you mean heaven=correct) time wouldn't matter, you could say that question in a seemingly infinite amount of ways but all you are really asking is, which door would you say is correct?

[@zachk3702]

+JKOROX That's true. "Which door would YOU SAY is Heaven/correct/whatever?" specifically referring to what the guard would say, and not 'would you say' being used as a figure of speech. The truth-telling guard would point to the Heaven door, because he always tells the truth. But the lying guard can't point to the Hell door (which he SAYS is Heaven, but is actually Hell), because he ALWAYS lies, ergo he points to the Heaven door as well.

[@xxxEmstarxxx]

+Dinesh Kishore I don't understand how being there yesterday has an affect on the answer

[@morbideddie]

To this day have no idea why people struggle with it. Initially it took me by surprise but as soon as you draw a diagram it becomes so obvious.

[@jpowner58]

This question popped up in my head whilst showering. The answer i came up with was to ask an obvious question that you know the answer to. "Am i dead?" Then you can easily know who's lying or not.

[@alhfgsp]

I missed the part where he said the truthful guard knows the other guard lies, and the one that lies knows the other tells the truth. To get into heaven you can't just determine which one the dishonest one is by asking one of them if they are standing on their heads then simply enter the door if that guard says "no" because another specification was that the dishonest one could be guarding heaven (you don't know if the dishonest one is guarding heaven or hell). So the only question to ask that would work without a doubt is, "what would the other guard say if I asked him wich door leads to heaven -door 1 or door 2"

[@parelpotje]

I love how smart Ricky always acts, but how he fucks up the question completely: The honest one is not necessarily standing in front of heaven.

[@57worldwide]

He doesn't have to forget, as it's a compulsion he isn't conscious of. It fits with the "he always lies" part of the problem, as there is no explanation of the motivation for the lie, or whether he lies uncontrollably or not. If he always lies, even when contemplating a hypothetical in his own head, then he may never answer the question. He could get stuck in an infinite loop lying to himself, "I would pick this door - no I wouldn't - yes I would".

[@margarita1776.]

Does anyone know where I can get magnificent riddles just like this one. ?? :)

[@1337w0n]

My solution is adapted from a similar problem where there are two paths, I need to find out which ones which And figure out which path is which (each may be guarding either path) AND bring back proof that I solved it, with two questions, and I took a picture of each answer. The questions I asked were: "Which way is the correct path? Indicate by pointing" (If their arms cross each others, the truth teller is opposite the correct path etc.) "Which way were you just pointing?" (the correct path.)

[@footballnerd277]

"This is where you need to use your gut feeling" "What as opposed to the pure logic that Ricky just used" It's sad that there are actually so many people out there who ignore logic and make decisions based on their gut feeling.....

[@profshad3429]

I get it. Your right people get confused

[@Conquestidore]

In fairness the question is specifically predicated on the liar/truth-teller aspect, which should limit what answers are expected, but yeah I'm pretty crap at spotting what should be asked out of the whole array of questions out there

[@Sahanavic]

Ricky leaves out a very important clause from the original puzzle. Though one only tells the truth, and the other only tells lies, it isn't known whether the liar guards the door to hell or heaven. You only have one question with which you can decipher which door is which.

[@R3fug333]

If he says no, he'd be lying initially. But it would be the truth because he didn't tell a lie. If he doesn't say anything afterwards, he was telling the truth.

[@eskiltho8308]
