These puzzles are always meant to be some form of lowKey insult. I get why most of you wouldn't know but some of you have to know these are jabs at the laymen not attempts to enlighten... spoiler alert, people have been terrible for a long time. In this case, it's a high vs low IQ semantic argument that if you aren't aware of ahead of time, was used to 'out you' in casual conversation about meaningless tripe. Unless of course you were a 'person of substance', in which case you would recognize the puzzle immediately and infer the solution as option A at about the point in the conversation where the editor paused for time to guess an answer. If you have never seen this puzzle before and knew the answer was A instantly, your IQ and/or education level is probably pretty high. And if you have to work it out, you're likely not of any meaningful substance. That was the gist of it. Quite of a few of these lowKey classist digs and conversational gotchas end up circulating among communities of people who want to feel high IQ without going through the 'proving it to other people' part. The original meta joke.

Yeah, the setting could make some optimizations I'm thinking: The potions last for 1 sentence (so you can ask them only once) and you know they hadn't asked something yet to each other The petrification also grants them immunity to spells (not magical artifacts like the ring), so you can't kill them without letting them free and risking the cleric attacking you, so you want 100% security.

[@macdjord]

There's a simpler way of solving this: Step 1: Assume Cedar is the cleric. Then his statement is equivalent to 'I am lying', which is self-contradictory. Thus, Cedar is not the cleric. Step 2: Assume Agan is lying. Then Beorn must be both a liar and the cleric. But then, 'Agan drank a lying potion' is true and 'I am not a cleric' is false, making Beorn's either-or statement correct, which contradicts him being a liar. Thus Agan must be telling the truth. Step 3: Assume Beorn is lying. Then, per Agan's statement, which from step 1 we know to be true, he cannot also be the cleric. But then, 'Agan drank a lying potion' is false and 'I am not a cleric' is true, making Beorn's either-or statement correct, which contradicts him being a liar. Thus Beorn must be telling the truth. Step 4: We know from step 3 that Beorn is telling the truth, and we know from step 2 that Agan didn't drink the lying potion, so the 'I am not a cleric' part of the either-or statement must be the true part. Thus, one of the other two must be the cleric. And per step 1, we know it isn't Cedar, so that leaves Agan as the Cleric by process of elimination. The truthfulness of Cedar's statement is irrelevant to the solution, so ignoring it leads to simpler logic. Just thinking about the problem for a bit makes this obvious: none of the other statements refer to Cedar at all, so we can't determine its truthfulness from them. And in order to determine its truthfulness from the statement itself, we'd need to know who the cleric is, and if we know that, we've already solved the problem.

[@Gamesaucer]

I solved this in a similar way but with a slightly different perspective. Step 1: Assume Cedar is the cleric (same as your solution), which doesn't work and therefore Cedar can't be the cleric. Step 2: Assume Beorn is the cleric and Agan is lying. Since Agan is lying, that must mean Beorn DID 'drink a lying potion' AND 'is a cleric'. Beorn's statement must then be a lie, but that's contradictory as the core assumption here self-evidently makes what Beorn is claiming the truth. This rules out half of all options where Beorn is the cleric. Step 3: Assume Beorn is the cleric and Agan is telling the truth. Since Agan is telling the truth, that means 'Beorn drank a lying potion' is false. Beorn's statement must then be the truth, but that's contradictory because 'Agan drank a lying potion' is false, and 'Beorn is not a cleric' is also false. This rules out the rest of the options where Beorn is the cleric. By process of elimination, Agan is the cleric. I think this is more straightforward because all steps have "assume X is the cleric" as their starting point. From there it's just checking whether a contradiction arises.

[@joelstevens5670]

I think you’re right about this [see initial comment] being the most efficient, up until step 3. To recap, the statements are: A - B is not both lying and a cleric. B - Either A is lying or I am not a cleric. C - The cleric is lying. My starting point was to look at whether C is lying or telling the truth (which is perhaps the natural way of approaching logic problems like these). In either case, C couldn’t be the cleric. Next, I used the same step of assuming A is lying, having noted that it makes the first part of B’s statement true. This leads to the contradiction you mentioned, so A is telling the truth. Now for step 3. The simplest approach is to look at B’s possibilities, since A’s and B’s statements refer mainly to B, while we know the other part i.e. A is not lying. If B is telling the truth, the 2nd part of his statement is true and he is not the cleric. Otherwise, B is lying and A’s statement says he is not the cleric. In both cases, A is the cleric.

[@absentcoder4552]

Yeah, when I was working out the logic on paper, I boiled it down to A: B != (L && Cl) B: A = L XOR B! = C C: Cl = L If A = L, then B = Cl && B = L If B = L, then A != L XOR B != Cl CONTRADICTION Therefore A = T I wasn’t good enough to go further.

[@arizahmad9850]

My family and I also used a different step 2 and 3. Step 1: Cedar is not cleric. Step 2: Assume Bjorn is cleric and telling the truth. Find out it's impossible. Step 3. Assume Bjorn is cleric and is lying. Find out it's impossible. Conclusion: Bjorn and Cedar are not the cleric. Didn't even have to figure out who was lying or truthing.

[@jkakokje3710]

This was a fun riddle, but I think one thing that could be made clearer is that Beorn's statement is an exclusive or (although I believe it's still solvable if it is an inclusive or). Generally, "either... or..." is still an inclusive or in logic, even though colloquially it's thought of as exclusive or.

[@sarahpowell671]

It turns out it doesn't matter, because Cedar's statement is actually a paradox if there isn't at least 1 liar and 1 truth-teller in the group (i.e., if all of them are liars or if all of them are truth-tellers). So once you work out that Agan and Beorn's statements are internally consistent no matter what operator you use (OR or XOR), and either both of them are liars or both of them are truth-tellers, you know Cedar can't be a truth-teller if both Agan and Beorn are liars. So Cedar has to be the liar, Agan and Beorn both have to be truth-tellers, and you can work out who the cleric is from their statements. If you follow that logic chain, you never get into a situation where Beorn's claim evaluates to (true X/OR true) and never have to worry about which operator it is. I thought it was very clever puzzle design, making the OR/XOR not matter, until I watched the video and they apparently based their whole solution around XOR...

[@zUJ7EjVD]

Not to mention, they didn't actually state that there weren't three truth potions or three lying potions. We were left to assume that wasn't a possibility.

[@nate_storm]

@@zUJ7EjVDyou don’t need to be told that they drank some of each potion, because their statements would be contradictory if they were all true or all false

[@LeonShadoo]

@@sarahpowell671 came here to say that. I thought the whole time it is an or connection not a xor and got the same result.

[@DutchDread]

@@LeonShadoo Yeah, I'm not a programmer, I tried working it out using just plain logic, but I disregarded Cedar almost immediately as irrelevant. He could not be the cleric because that would result in paradoxes either way, and all he really said outside of that is that the cleric is either lying or telling the truth, which tells us nothing. He seemed like red herring. Then I tried making different scenarios. If A = Truth then: to list the different options so I could follow their logic one by one and discard them. Problem is that once I got to "if B is lying then" I had no idea what to actually put down there as options because I could not figure out how IN THIS SCENARIO, truth and lies would be interpreted. But it really didn't matter because I already had a path that as far as I knew could be accurate, and these riddles always have only 1 potential path that succeeds. If A is speaking the truth then B = mage (easier for the brain than "not cleric") and speaking the truth. Then from the two options for B when speaking the truth only the option "A telling the truth and B is a mage" would fit, which would mean A HAS to be the cleric, unless I am missing something. Problem is of course that this relies on riddle logic that there is only 1 possible outcome.

[@Inkyminkyzizwoz]

The most I managed to work out was that Cedar's statement meant that they couldn't all have drunk the same kind of potion and that Cedar couldn't be the cleric, but beyond that I was stuck

[@RaichuKFM]

I read Beorn's statement as an inclusive or and am rather bamboozled by the reading that it's an exclusive or, but this is a nice puzzle where either interpretation gets you the right answer. That way the focus is on the logic and not the exact way you formalize a natural language either/or statement. Thanks, Raymond Smullyan! If I bet someone $5 that "Either most ducks have wings or most ducks have feathers" was false and they took me up on it, I don't think "Ahah! But most ducks have *both* wings and feathers!" would get me the $5.

[@SoloHen]

This was a fun riddle, I personally solved this by translating the statements and their inverse into terms of logic gates, and making inferences with the translated sentences (My Solution here) Translating to terms of logic gates If Agan is truthful, then - Beorn is lying NAND Beorn is a cleric. Which is equivalent to: - Beorn is lying XOR Beorn is a cleric XOR - Beorn is truthful AND Beorn is not a cleric If Agan is lying, then - Beorn is lying AND Beorn is a cleric If Beorn is truthful, then - Agan is lying OR Beorn is not a cleric If Beorn is lying, then - Agan is lying NOR Beorn is not a cleric Which is equivalent to, - Agan is truthful AND Beorn is a Cleric If Cedar is truthful, then - Cleric is lying If Cedar is lying, then - Cleric is truthful Logical inferences To make inferences to eliminate options, the statements that have the least cases should be considered first to quickly find information Can't do anything with Cedar's statements without any idea on the Cleric, for now So, start with the AND statements, as they only have one case each Assumption - If Agan is lying, then Beorn is lying AND Beorn is a cleric Conflict - However if Beorn is lying then, Agan must be truthful which contradicts the previous statement. Conclusion - Thus Agan is truthful Next statement to consider is the OR statements, with at most 2 cases each. (Solution can be found by assuming either B or breaking down A, but I chose the former) * Assuming B Given - Agan is truthful - Beorn is not the cleric as Agan is truthful Assumption - If Beorn is lying, then Agan is truthful and Beorn is the Cleric Conflict - However if Beorn is lying, then he is the Cleric which contradicts the given statement derived from Agan that he is not. Conclusion - Beorn is truthful Given - Agan is truthful - Beorn is truthful - Beorn is not the cleric - Cleric is Agan or Cedar Assumption - Cleric is Cedar Conflict - Cedar being the cleric is self contradictory given his statement Conclusion - Cleric is Agan Given - Agan is Truthful - Agan is the Cleric Conclusion - Cedar is Lying Solution - Agan is the Cleric - Agan and Beorn are truthful - Cedar is lying

Beorn's statement is true no matter what, he's just spitting logical conclusion about Agan's statement

[@KnakuanaRka]

I found an easier way of thinking about this one involving checking each possible person to be the cleric. Also, Agan's statement can be reworded more clearly; NOT (A AND B) is the same as (NOT A) OR (NOT B), so Agan's statement can be recast as "Either Beorn is T or Beorn is not a cleric". If Cedar is the cleric, his statement is basically "I am lying", which is a contradiction, so he can't be the cleric. If Beorn is the cleric, both his and Agan's statements have an "or Beorn is not the cleric" clause that can be dropped (since A OR false is the same as A). So Beorn says Agan is lying while Agan says Beorn is telling the truth, which is also a contradiction. If Agan is the cleric, everything works. Agan and Beorn are both telling the truth since Beorn isn't the cleric, and Cedar is lying about Agan. So this is the only one that works, and Agan must be the cleric. Edit: I interpreted either/or as being OR rather than XOR (both can be true in OR), but it didn't matter.

Cedar doesn't give any information other than her not being the cleric though. Once we rule her out, the only "info" she gives is that the cleric has either drank a truth or lying potion, ... which really doesn't say anything. You don't need her to finish the riddle.

[@joshuah4952]

I'm not sure that the "Either" in Beorn's statement is enough to conclude "exclusive or" rather than "at least one of these". It's a moot point anyways, since you reach the same conclusion with either interpretation.

[@SomeRandomFellow]

I started by going off of Agan's statement, since the "and" seemed more restrictive. What I got seems to be (to me) a simpler solution. Here is my write-up: *Statements for reference:* Agan: _Beorn is not both a lying-potion drinker and a cleric._ Beorn: _Either Agan drank a lying-potion or I am not a cleric._ Cedar: _The cleric drank a lying-potion._ *The solution:* 1. Assume Agan drank a lying-potion: Agan Beorn Cedar Lying? Y Cleric? 2. By Agan's (lying) statement, Beorn is both a lying-potion drinker and a cleric. Agan Beorn Cedar Lying? Y Y Cleric? Y 3. However, Beorn's (lying) statement is true, as Agan drank a lying-potion. So, (by contradiction) Agan must have drunk a truth-potion. Agan Beorn Cedar Lying? X Cleric? 4. Assume Beorn drank a lying-potion. By Agan's (truthful) statement, Beorn is then not a cleric. Agan Beorn Cedar Lying? X Y Cleric? X 5. However, Beorn's (lying) statement is true, as Beorn is not a cleric. So, (by contradiction) Beorn must have drunk a truth-potion. Agan Beorn Cedar Lying? X X Cleric? 6. By Beorn's (truthful) statement, Beorn is not a cleric. Agan Beorn Cedar Lying? X X Cleric? X 7. If Cedar is telling the truth, there is no cleric because everyone drank a truth-potion. So, Cedar must be lying, making Agan the cleric. Agan Beorn Cedar Lying? X X Y Cleric? Y X X Interestingly, Beorn's statement of exclusivity was not a factor in determining this solution, which is nice because I wasn't sure how to interpret it when solving this puzzle. However, I assume part of the idea behind this puzzle is to expose people to exclusive-or operations.

[@FireCat37]

Cedar's statement isn't actually necessary to solve this riddle after we realise they cannot be the cleric. Assuming there is only one cleric (which is given), Agan and Beorn's statements alone are enough to determine which is the cleric. T and T - forces Agan to be the Cleric. All other options (TF, FT, FF) get some contradiction between the two statements, regardless of Cedar's, so they are impossible under the rules of the riddle.

It doesn't really apply to A's statement, because that was the exclusive or, but... wait I think I did the wrong math but got the right answer.

[@Primearch-GG]

This is a nice twist on the original riddle, since the solution to that is quite simply asking one of the two what the other's answer would be and choosing the opposite regardless of if you know which is the liar or truth teller.

[@ThijsAnglim]

This is like the magic crystal riddle with one less person.

[@adrianmejia9096]

Another riddle by TED-Ed!

[@haroldtourjee3213]

At 2:49 you declare that Agan lying means that Beorn must be a F-drinker and a cleric, but that's not necessarily correct. Specifically it's the ambiguity of "not both" which can be interpreted as either "Agan is saying that Beorn is neither of these" or "Agan is saying that Beorn is missing at least one of these two qualities." The video is interpreting it as the second way, meaning that in order for him to be lying then Beorn must be a lying cleric, but the first interpretation is just as valid in English. A quick Google search confirms this and finds a few sites that recommend avoiding using "not both" due to this very ambiguity.

[@klikkolee]

Even with the historical use, I really don't find the first interpretation to be reasonable. There is already "neither" as the predominant way to say multiple things are all false, so there is no good reason to interpret "not both" as anything other than the negation of "both", which is precisely the second interpretation. This is consistent with what is by far the most common use of "not both", which is to clarify that a use of "either" is exclusive, not inclusive -- "either A or B, but not both"

[@Schmidtelpunkt]

English is a flawed language for riddles. 9 out of 10 riddle online are made complicated solely because the English language reaches its limit of precision...

[@RafaelCouto]

As soon as I realized this ambiguity I gave up on the problem. Thanks for explaining it clearly.

[@joshnewman9581]

It is not ambiguous to people who understand boolean algebra. “Not both” implies a NAND statement which is equivalent to saying: Beorn is not lying OR Beorn is not the cleric. However, if you are not someone who codes, the phrasing of “not both” can understandably be confusing.

[@RafaelCouto]

@@joshnewman9581 I'm a coder and I think the ambiguity still holds. The challenge ain't about machine code being executed, it's about lies and statements from everyday human language.

[@TheOGLaws]

This is bringing out the nerd in me and I love it ❤

[@ThijsAnglim]

Spoilers: We know who the cleric is, but I am going to guess Beorn is the rogue because he is the one who swiped the cursed skull without checking.

[@idanbhk3875]

And Cedar is the fighter, not really overthinking about the answer they give, talking is for weaklings anyway.

[@darexinfinity]

FINALLY all my years of study computer science has paid off!

[@idanbhk3875]

FINALLY all my years of DMing have paid off!

[@thedapperrabbit113]

One of the few puzzles I actually paused to solve. It was a lot easier when I started writing things down.

[@BakudaSon]

Woo! I actually figured this one out before the answer reveal~

[@HalfDecentVideos719]

The correct answer is that the dungeon master is playing with the other players, not against them

[@whitegx-k5i]

when i solved this one all my initial assumptions were correct and i had to do all it again to make sure it was the only possible outcome

[@johnnye87]

As far as I can tell, assuming that we define A "lying" as meaning that BOTH his propositions are in fact true, while B "lying" means that either BOTH OR NEITHER of his propositions is false, then: (spoiler) 1. A and B are both telling the truth; 2. B is not the cleric; 3. This would create a Liar's Paradox if C was the cleric, so 4. The cleric must be A (and thus 5: C is lying).

[@teslestienstlektan2276]

First *that* video on *that* site and now a Ted Ed riddle about DND? These are good times.

[@misslotalotus1500]

so Agan's plan is well executed, congrats Agan for the engagement

[@themasterprocrastinator4933]

I had a passing thought halfway through the riddle, "what if romance lol" and it actually happened fr? Crazy (not complaining tho, gimme sequel)

[@alexduran3227]

I’m usually pretty good with logic puzzles. But this one straight up broke my brain. I would just randomly put the ring on one of them and hope for the best.

[@siegebug]

Using the liar paradox to make people ignore C and to obscure C might be lying, this is a brilliant riddle.

[@tinywafflerat]

babe wake up new teded riddle dropped

[@zebfross]

Love these! I did regular or instead of exclusive or and got a different answer. Tricky riddle!

[@ninahouse1209]

The music is just like the music of the tarot riddle!!!

[@JojoCat2008]

Addison Anderson's voice never gets old. It's literally the most memorable voice in TED Ed.

[@oliviadandrea6152]

this is one of the first one of these i actually could figure out… i feel like a genius 😂

[@khloebell4644]

Plz make more riddle videos I was sad that you guys stopped makeing them for a while

[@PhoenixHunter_]

Beorn was the MVP of that team trying to confuse us with the XOR statement...still solved it when I realized it was an XOR and not an OR lol

[@aryanuddin1903]

I ACTUALLY SOLVED THIS ONE! As a fourteen year old I'm very happy.

[@jefferydavidson5347]

Realistically the classes of each should be pretty obvious based on their gear and stuff

[@DragonboyX_7]

This riddle is so difficult, wow. I couldn't solve this even if i knew how to.

[@foxzero99gaming16]

Proud to say I paused the video, and thought for a while and then shouted out "IT'S AGAN!" in a middle of food court full of people

[@wooden49]

2:43 If Agan is lying I think Beorn can also be a truth-telling cleric or lying non-cleric In Boolean algebra, inverse of ~(A and B) is A or B Not the “A and B” Of course, Beorn can still be lying cleric, it just cut out the scenario where Beorn is truth-telling non-cleric

[@paddy-daddy]

TEDED I LOVE YOUR RIDDLE VIDEOS PLEASE PLEASE PLEASE MAKE MORE

[@32ekoc]

I kind of have an issue with this riddle. If one drinks a truth potion then why/how can you tell a lie? Even if you follow it up with a truth, you still lied when you shouldn't be able too.

[@rossplendent]

"The potions they drank will compel each to answer one question with either the truth or a lie." They then proceed to answer "Which of you is the cleric" with a series of statements that do not actually answer the question. So either the potions don't actually work, or "answer with either a true or a lie" means they could just say any statement at all, as long as it's either a truth or a lie. Someone who drank a lie potion could answer "Apples are not fruit."

[@eshelsh1905]

It's not an unknown rule you need to interpret, it's how the potions *you made* work. also common sense.

[@justwaiting5744]

I've been waiting for another riddle! Huzzah!

[@jakovsaric9492]

i somehow took cedar as truthful and still got correct answer
