ITT: We do fun INDUCTION brain teasers (hat puzzles etc.)
Poast new message in this thread
Date: April 26th, 2026 11:27 PM Author: high-end private investor crackhouse Here is a common variation of the HAT PUZZLE. Unlike the TTT blue/red button thought experiment, this is a LOGIC problem (not a feeling problem) that has a correct answer.
----
Three poasters are competing for a girl's attention. She's mildly receptive to their jestermaxxing and decides to give them a few minutes of attention. She has them all face each other and tells them: "I'm going to place a hat on each of your heads so that you can only see each other's, not your own. Each hat is either red, blue, or yellow (but there may be multiple or none of a given color). You will all guess at the same time. If any of you gets your hat color right, I'll make out with each of you for like 5 seconds. You may agree on a strategy beforehand and let me know when you're ready."
What strategy can they use to ensure that at least one of them guesses their own color correctly? |

Date: April 26th, 2026 11:37 PM Author: high-end private investor crackhouse Sorry I stealth edited that poast to clarify that you don't have the hats yet when you're agreeing on the strategy. Your task is to figure out how to guarantee that one of you gets it right when you all guess your colors simultaneously.

Date: April 26th, 2026 11:49 PM Author: Misunderstood Antidepressant Drug Nursing Home i'm stumped. if you can't share the other 2 men's hat colors as part of a strategy, i don't see how it works.
just seeing the other two men's hat colors gives you no information about your own hat color since there are no rules governing color distribution (your hat color could still be Y, R, B regardless of the other men's colors). |
|
Date: April 26th, 2026 11:51 PM Author: high-end private investor crackhouse Well the idea is to come up with a way to guarantee one of you is correct. That's a slightly different question from "how does anyone know their own color?" (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49845662) |
|
Date: April 27th, 2026 12:05 AM Author: Misunderstood Antidepressant Drug Nursing Home but it's the same question, because you are looking for a strategy in which everyone gives Y/R/B as their own answer such that at least one is correct.
if the rule is "All or none of your hats could be Y/R/B in ANY combination regardless of the color of any other man's hat" then there can be no strategy because there is no rule. seeing the other hats provides no information as to the distribution of colors (no rule), other than the information about what the other 2 men's hat colors are, but this cannot be signaled as part of the strategy.
there is nothing we can all agree to say that guarantees one of us is right.
edit: I see it now |
|
Date: April 27th, 2026 12:10 AM Author: high-end private investor crackhouse Well you're thinking in the right direction of like, aren't there too many possibilities to cover with the three guesses? But the problem space is smaller than it seems. It helps to assign numbers to the colors and start looking at the possibilities that way.
edit: "other than the information about what the other 2 men's hat colors are, but this cannot be signaled as part of the strategy." – They can't "signal" that information bc they're guessing simultaneously, but they can still incorporate it into their guesses |

Date: April 27th, 2026 12:16 AM Author: high-end private investor crackhouse It could be made a clean logic problem if you specified that everyone on Earth can be assumed to be a rational actor.

|
Date: April 27th, 2026 12:18 AM Author: magical scarlet black woman No. The logic exists independently of whether any specific individual is a rational actor. With red, you always live. With blue, you only possibly live contingent on others' acts. You either understand this and live, thereby passing the IQ test, or you don't understand this and perhaps die, thereby failing the IQ test. You failed.

Date: April 27th, 2026 12:34 AM Author: Vigorous embarrassed to the bone coffee pot Your risk is way too high. Your projected outcome is skewed towards your own demise based on values when most people are going to push red to save themselves and not have to worry about whether they'll be killed. You'll never get to 50% of people who are willing to risk dying for other people. Therefore 100% of red pushers live, 100% of blue pushers die, 100% of the time.

Date: April 27th, 2026 12:45 AM Author: Vigorous embarrassed to the bone coffee pot All anyone has to do to not die is push red. It's safe, it's secure. Blue is giga idealistic.

Date: April 27th, 2026 10:42 AM Author: Curious buck-toothed wagecucks I was team blue for a moment until I realized that red is better
I do think it matters if you stipulate whether kids are involved or if you limit it to people who are generally competent to consider the issue. If there’s lots of kids etc involved then you may figure that there’s enough blameless non rational actors we want to save that the ethical choice is to switch to blue and try to save them. If you’re assuming a game theory sterile abstraction where “everyone” is just rational actors then it’s absolutely red. |
|
Date: April 27th, 2026 10:59 AM Author: coiffed slate stage if we assume everyone is a rational actor the hypo is solved with red. but we know that's not true.
empirically we can see many people choose blue and cannot be dissuaded. so we know in reality many people will choose blue.
the hypo requires universal participation, so "opting out" by choosing red is bullshit. you're still participating, team red interprets it as a moral choice. but we know from observation that many people will choose blue and that humans are perfect rational actors. |
|
Date: April 27th, 2026 12:14 PM Author: magical scarlet black woman It doesn't matter whether or not everyone is rational, it just matters what you do contingent on what everyone else is doing. You either definitely live, or you possibly die, irrespective of everyone else's rationality. (Although if you want to express it in game theoretic terms, "red" is a strictly dominant strategy for everyone, therefore you should absolutely pick "red" in all circumstances, and "all pick red" is a dominant strategy equilibrium) Life is a big IQ test. Those that pick "blue" fail. |
|
Date: April 27th, 2026 10:46 AM Author: Curious buck-toothed wagecucks I think the key issue is whether or not anyone is constrained from making the logical decision. If there are people who are going to push blue because of disability or they’re too young etc then I think there’s a moral argument that everyone has to choose blue (and you individually have to) because it will stop harm. That’s what the blue people are assuming—they start off with an assumption of “well some people will always choose blue” so we need to do the option that saves them. But if we are in pure sterile abstraction thought land, anyone whose initial impulse is blue is an idiot.
The funny thing is that these people are probably thinking along Kantian lines when they hit blue but 1) red is fully consistent with categorical imperative and 2) Kant’s political writings are explicit that you have to go with the world you want to see. If you’re a lib sitting and thinking “well maybe nobody should pick blue in the first instance but somebody will so I’ll save them and pick blue,” then it’s a self fulfilling prophecy. |

Date: April 27th, 2026 10:50 AM Author: Vigorous embarrassed to the bone coffee pot The universe doesn't care about your feelings. Blue is a death sentence. You subliminally want to die. You only have one option to survive, to push red. Women, children, the indigent. Their best hope is for someone to convince them to preserve themselves. All blue pushers are going to die 100% of the time. It's very tragic but we cannot risk our own lives to save everyone. It's black and white here. You either live or you kill yourself. The blue pill is that most people will choose life. Can't save everybody, unfortunately. (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49846415) |

Date: April 27th, 2026 12:55 AM Author: high-end private investor crackhouse Crrrrr SOLUTION: (Before you go on - if you have a CS background and haven't figured it out, try again with the hint that it involves modular division.)
You assign each color a number 0, 1, or 2.
You reason that when the three hats' numbers are added up, the total 0-6 falls into one of these categories: - { 0, 3, 6 }: have a remainder of 0 when divided by 3 - { 1, 4 }: have a remainder of 1 when divided by 3 - { 2, 5 }: have a remainder of 2 when divided by 3
So if you each cover one of those 3 possibilities, it's guaranteed that exactly one of you will be correct.
You assign one person to remainder 0, one to remainder 1, and one to remainder 2. Everyone adds up the other people's hats and guesses their own hat so that that the total divided by 3 has their assigned remainder. |

|
Date: April 27th, 2026 5:32 PM Author: high-end private investor crackhouse For example: Red = 0, Yellow = 1, Blue = 2
I am assigned remainder 0. - If I see a red hat and a yellow hat, the total is 1, so I need to guess Blue for a total of 3 in order to get a number in my assigned category. - If I see two red hats, the total is 0, so I need to guess Red for a total of 0 to get a number in my assigned category. |

Date: April 27th, 2026 1:42 AM Author: high-end private investor crackhouse NEXT (not "inductive," just a logic puzzle): This one involves some real-world assumptions you can ask about if you have questions. It's not quite as abstract as the hat ones.
I capture you and lock you in my dungeon as my slave. I treat you well and feed you and stuff and you enjoy spending time with me BUT you'd much rather be free to go back to your life. After a couple weeks I tell you that I'm going to give you a chance to escape. There are three switches in your cell that have always been a mystery to you. They're each marked "on" and "off" and you've kept them off after some initial experimentation.
I tell you that each switch connects to a lightbulb in my room directly above the dungeon. Each lightbulb is controlled by one switch. I tell you to do whatever you want with the switches until tomorrow morning, at which point I will take you upstairs to where the lightbulbs are. If you can figure out which switch corresponds to each lightbulb, I'll set you free.
What is your strategy to escape? |

"A bus full of ugly people unexpectedly crashes and kills everyone on board
Everyone shows up at the Gates of Heaven where God comes to meet them all Himself.
"Gee guys, I didn't intend for that to happen, I'm really sorry. I can't just resurrect you all, but to make up for it I'll grant you all one wish before I let you in."
The first person steps up and thinks for a moment. He says "You know God, I've been ugly all my life. For once I would like to know what it is like to be beautiful. Make me beautiful." So God snaps his fingers and it is so.
Everyone else starts chattering amongst themselves at such a brilliant idea. They all start wishing for the same thing.
God steps up to the last guy in line who is laying on his side laughing so hard he is crying. After several minutes of patiently waiting, God finally says "Now what in Heaven could be so funny boy?" The man stands up, wipes a tear from his eye and says "Make them all ugly again."" |

|
Date: April 27th, 2026 5:14 PM Author: high-end private investor crackhouse Yeah, his answer works for slightly different formulations of the problem. In this case there are 7 possible sums, 0-6. You need to break down those possibilities into three categories, one of which must be true.
We can break it down into: - { 0, 3, 6 }: have a remainder of 0 when divided by 3 - { 1, 4 }: have a remainder of 1 when divided by 3 - { 2, 5 }: have a remainder of 2 when divided by 3
Since we have 3 guesses, we have each person construct his guess so that the total meets his assigned condition (remainder 0, 1, or 2). One of them will be right and the other two will be wrong.
For example: Red = 0, Yellow = 1, Blue = 2
I am assigned remainder 0. - If I see a red hat and a yellow hat, the total is 1, so I need to guess Blue for a total of 3 in order to get a number in my assigned category. - If I see two red hats, the total is 0, so I need to guess Red for a total of 0 to get a number in my assigned category. |

Date: April 27th, 2026 4:27 AM Author: high-end private investor crackhouse NEXT QUESTION: We live in a strict matriarchy where every woman has to pass a logic exam before she is allowed to marry and therefore all married women are perfect reasoners. Every woman knows (from observation) whether each man in the kingdom is faithful to his wife, EXCEPT for her own husband. It is taboo to tell a woman whether her husband is faithful, and no one has done it or would ever. Also, all of the women have great hearing and would definitely hear a gunshot from anywhere in the kingdom.
One day, the Queen tells everyone that she is observing male infidelity in the kingdom and wants to eradicate it. She says that women with cheating husbands are now legally required to shoot and kill their husbands at midnight after discovering the infidelity, starting that night.
How does each married woman know when/if to kill her husband? |
|
Date: April 27th, 2026 10:29 AM Author: coiffed slate stage every woman tallies up how many cheating men are in the kingdom and writes down the numner. only two sums are possible: women with faithful husbands will write down N, the true total, and women with unfaithful husbands will write down N-1. thus, if you wrote down N-1 you can deduce your husband is unfaithful and shoot him at midnight. (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49846346) |
|
Date: April 27th, 2026 11:48 AM Author: Awkward Menage Psychic I don’t think that works. For instance if I see 5 cheating husbands, I don't know if N = 5 (my husband is faithful) or if N = 6 my husband is the 6th cheater). There has to be something that gives the first wife a reason to kill then the inductive chain starts but I’m having trouble intuiting it.
Wait it might be simpler than I was thinking. They might just count down the nights, and since they are all perfect reasoners they literally shoot at the same time on the last night. |
|
Date: April 27th, 2026 11:58 AM Author: coiffed slate stage if every woman shares what they believe is the total number lf cheating husbands, everyone with the lower number can deduce that their husband is unfaithful. they know there is at least one cheater because the queen announced it. and the two different sums confirm it.
let's use your numbers and say that there are 10 women total and 6 have unfaithful husbands. the 4 with faithful husbands will say there are 6 cheaters. the 6 with unfaithful husbands will say that there are 5 because they only can't see their own. this doesnt break the taboo because none of the wives are telling the other ones their husband is cheating. the numbers could all just be written anonymously too. the women with unfaithful husbands know the number the wrote down and can deduce their husband is the cheater. |

if this was on the LSAT and both mine and chokes answers were available, id select his because it's "best", i.e. what the drafter would think is best. |

Date: April 27th, 2026 11:58 AM Author: Floppy Property Cuck Assume 3 wives in the kingdom, exactly one of whom is cucked (but ofc doesn't know it). On day one, there are no murders because no wives know they are cucked. On day two, same. On day three, there has to be at least one murder bc queen said there is infidelity. Cuckwife observes that other two wives are not cucks. Cuckwife therefore deduces that she is the cuck and murders her husband on day three.
Solution is generalizable to greater populations and numbers of cucks.
Edit: nm I fucked up and am retarded. On day one, cuckwife would deduce that she is cuckwife and murder her husband on day one. Oomox explains below. |
|
Date: April 27th, 2026 12:11 PM Author: coiffed slate stage this works too and is probably the answer the hypo is seeking. women are not compelled to root out the infidelity, so they wouldn't have to share the total number of cheaters like in my solution. but they would arive at the same conclusion after a certain number of nights (if we assume they're tracking them and have perfect memory).
in my solution with 10 women with 6 unfaithful husbands, the women who could see 5 cheaters would realize on the 6th night when the queen announces infidelity still remains that their husbands are cheaters and will shoot them after midnight. i was wondering where the perfect hearing component worked here. it's necessary for all the women to know whether murders occurred. |
|
Date: April 27th, 2026 12:12 PM Author: Awkward Menage Psychic yeah I think thats it. they wait the number of nights and all shoot at the same time on night N given the number of cucks (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49846638) |
|
Date: April 27th, 2026 1:51 PM Author: high-end private investor crackhouse That's really close. More precise SOLUTION: If there's only one cuckwife, she shoots her husband on the first night because the Queen announced that *someone* was cheating and she doesn't see anyone else's husband cheating. If there are two, both kill their husbands the second night because they only know of one cheater and there were no shots on the first night. If there are three, all three kill their husbands the third night because they know of two cheaters and there were no shots on the second night. And so on.

There are 100 prisoners in a for-profit prison in a brand new SmartCity. Their sadistic AI warden decides to play a game. The prisoners will stand in a line on a ramp, each of them able to see all of the prisoners in front of them. A Red or Blue hat will be placed on each person's head. As in the last case, they can't see their own, just those of the people in front of them. Starting at the back of the line, each person will have to guess whether he has a Red or Blue hat. If he's wrong, he's executed; if he's right, he gets an upgrade from jail to the VR data harvesting labs where at least you get to play games. Everyone can hear the guesses of everyone before him.
They can strategize about it beforehand. How can they ensure the maximum survival possible of the group? |

Date: April 27th, 2026 2:25 PM Author: magical scarlet black woman I don't think there is a way they can all be guaranteed to survive, the last in the line (i.e. the first to guess) has no path to obtain information about his own hat, but he can see all the other hats in front of him and he is the first to guess so he ought in principle be able to find a way to signal the information he has to the other 99 players in a way that they can sequentially use and pass forward (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49846973) |

Date: April 27th, 2026 2:28 PM Author: magical scarlet black woman are they restricted in what they can say e.g. only "red" or "blue" to guess their own hat, or can they also say other things? e.g. if each player is permitted to speak a number, they can allocate 1 and 0 to each other colors and each plater add up the hats they see in front of them and pass that information forward so that X(p)-X(p-1) = 0 or 1 so that each player can know the color of their own hat but the last in the line cannot do this and so may croak |

edit: The result doesn't matter *if* we assume they're perfectly rational actors, which we are. If we stipulate that they may make mistakes, it does matter. |
|
Date: April 27th, 2026 2:18 PM Author: Awkward Menage Psychic What if they agree beforehand that the first prisoner’s word is not a sincere guess but a code bit where “Red” means even parity and “Blue” means odd parity? That doesn't technically violate literally Red/Blue (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49846950) |
|
Date: April 27th, 2026 2:26 PM Author: high-end private investor crackhouse Crrrr! SOLUTION: The first prisoner's answer reflects whether he sees an even number of [designated color] hats or an odd number. He has a 50% chance of survival and then everyone else can get theirs right for sure based on that first answer and the answers of those that go before him.
(If there's the possibility that the prisoners make mistakes deducing from the answers before them, we do need the results to be audible to everyone.) |
|
Date: April 27th, 2026 2:25 PM Author: coiffed slate stage if they can hear the results of the guess it works similarly to card counting. they could assign the hats a binary 1 or 0 and then communicate the count by assigning each color even or odd. e.g. red = 1, blue = 0, guessing red = even, guessing blue = odd.
if the last prisioner sees 40 red hats he would announce even. if the next prisoner sees 40 red hats he knows his is blue. then each prisoner follows suit.
i guess knowing the result of the guess isn't necessary if we assume the prisoners execute this perfectly. it would be necessary to confirm the accuracy of the count if someone makes a mistake. if they execute it perfectly, 99 prisoners are sure to live. the last guy is 50/50 regardless. i assume for the purposes of the hypo he will cooperate with the strategy even though he won't benefit personally? |

He tells them all that there is a single room in the basement, which he menacingly calls "The Playroom," containing nothing but a switch and corresponding tacky chandelier. Every day after work and before infidelity, he heads over to his UNITS and uses a (pseudo)RNG website to choose a poaster to escort to The Playroom.

Date: April 27th, 2026 5:31 PM Author: histrionic hateful roast beef dilemma first guy turns it off
for every other guy, they will turn it on if they have never flipped the switch. if it's already on, they do nothing.
whenever first guy comes around again, he turns it off. at some point he will have done this N-1 times
will take a very long time but uh guarantees everyone should get to go home within 10000k days or so
it's something like this + minus the requirement of the "first guy" (since they dont know who goes first) and instead getting everyone to agree on the special man |

Date: April 27th, 2026 5:39 PM Author: coiffed slate stage i was thinking the same thing but you just assign one poaster as the counter. if he goes in first he would turn it off. but that would take longer that than than the remaining life expectancy of the 50 poasters. and they don't even know if all the poasters remain, including the counter (or first oick in your version).

Date: April 27th, 2026 5:55 PM Author: coiffed slate stage if the the rng is completely random you can easily calculate what confidence everyone is comfortable with and go with that date. after a year it's very high.
if you want to be certain by brute forcing with the light switch it'll take a long time. no chance everyone survives that long. and even if the did, i think everyone would choose to spent ~1 year in the unit and have a really good chance of surviving than potentially decades there and waiting for absolute certainty. |

Date: April 27th, 2026 5:43 PM Author: high-end private investor crackhouse Crrrrr! The correction at the end is crucial.
SOLUTION: The group designates a Counter. Everyone except for the Counter interacts with The Playroom as follows: If it's your first time in there and the light is off, turn the light on. Otherwise, do nothing.
The Counter interacts with The Playroom as follows: If the light is on, turn it off and add a tally to the POASTERS count. When you've recorded 49 fellow poasters, the next time you're summoned, you can tell CSLG you're ready to bounce. And yeah it will probably take a while. |

Date: April 27th, 2026 5:47 PM Author: Awkward Menage Psychic But how do they figure out that the switch is initially set to "off"? The rest of the group not just the person escorted into the playroom? (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49847457) |

Date: April 27th, 2026 5:52 PM Author: coiffed slate stage on = i turned it on for the first time.
if the counter goes first he turns it off. he's the only one that can switch the switch off. everyone else only switches it on if thats the first time they've been able to do so.
counter just has to count to 49 times he turned the switch off. |

Date: April 27th, 2026 5:54 PM Author: high-end private investor crackhouse Oh yeah I guess we need to special-case the first night (and this is diff from what ohnoes said). If you're the first person and you're the Counter, turn it off if it's on but don't count it as a fellow POASTER. But the normal rules apply to everyone else. The first person gets counted the same whether the light is on or off when they enter. (http://www.autoadmit.com/thread.php?thread_id=5860893&forum_id=2Vannesa#49847470) |
|
Date: April 27th, 2026 5:49 PM Author: coiffed slate stage it would take a decade and potentially beyond the range humans can live and also requires all 50 poasters to remain alive, which is a near statistical certainty will not occur.
best bet is wait a year and yolo that everyone has gone, which is near certain by then. |

Date: April 28th, 2026 3:45 AM Author: high-end private investor crackhouse NEXT QUESTION: There are 20 kids locked in The New Playroom (all the units from the other Q combined into one) and they're all supergeniuses capable of perfect reasoning.
SpacePorn says, "Tomorrow I will give you a chance to leave. I'll put a Black or White collar on each of you so that you can see each other's but not your own. You will all guess your collar colors at the same time; anyone who gets it right will be set free. You may prepare a strategy."
As soon as SP leaves, the children whisper excitedly. They already have a plan for how to escape as a group as long as they have 10 or more kids on the outside. So this could be their chance!
But can they GUARANTEE that 10 or more kids get their colors right? What's the most children they can ensure answer correctly? How do they achieve that result? How would they do the same for other numbers of children? (He might capture 1 or 2 new ones tonight.) |

If Spaceporn gags them to prevent talking he still didn't restrict their movement. When Spaceporn steps back and says "guess" Kid 1 simply walks around the room and physically pushes everyone with a Black collar to the left wall, and everyone with a White collar to the right wall. Since Kid 1 can see everyone else's collars this is easy. Then Kid 2 grabs Kid 1 and guides them to their respective wall. Now everyone knows which group they belong to, and they all guess correctly at the exact same time |

The novel part of the problem is the splitting into subgroups thing. |
|
Date: April 28th, 2026 4:16 PM Author: Irradiated carnelian address mad-dog skullcap first, the kids divide themselves into two equal group, a good phenotype group and a bad phenotype group. if we have an odd number of kids, the kid with the worst phenotype sits out.
each kid in the good phenotype group is paired with one kid in the bad phenotype group
when it comes time to guess: - each good phenotype kid guesses that his collar is the opposite of the collar he sees his bad phenotype partner wearing; this is easy to remember, because he will hope not to have similarities with his bad phenotype partner - each bad phenotype kid guesses that his collar is the same as the collar he sees his good phenotype partner wearing; this is also easy to remember, since we should all aspire to be like people with good phenotypes
this guarantees k/2 rounded down correct guesses, where k is the number of kids. so we get our 10 if we have at least 20 kids
collar -> guess matrix: b b -> w b b w -> b b w w -> b w w b -> w w

The Cummy Poasters Problem
A group of poasters gets together and one thing leads to another. A lot of bros help each other achieve climax and things get messy.
One of their wives joins the group later after her date. She looks around and starts laughing. "You know, at least one of you has dried cum on your face." Assume none of the poasters has looked in the mirror since their sexual exploits and no one knows whether he has cum on his face. The poasterwife says, "I'll buy anyone a drink who's able to tell me whether they have cum on their face. I'll keep asking the whole group throughout the night if anyone knows. Anyone who can correctly tell me gets a free drink."
What happens next? |

Date: April 30th, 2026 2:24 AM Author: high-end private investor crackhouse NEXT QUESTION: You're babysitting autistic twins, Alice and Bob, both perfect reasoners. You need a break to make a phone call. You tell them, "I'm going to write a number on each of your foreheads. They are consecutive positive numbers. Without telling each other the numbers you see, I want you to go back and forth asking and telling each other whether you know what number you have on your own head. Got it?"
They both nod. After you write the numbers, Bob asks Alice, "Do you know your number?" Alice replies, "No. Do you know your number?" Bob responds in the negative and asks if Alice knows; she has the same response as before.
After another round, you excuse yourself and make your phone call. You get back just in time to hear Bob say, "No. Do you know your number?" and Alice respond, "Yes, my number is 163."
What was Bob's number? How many times was the question asked before Alice figured out her number? |
|
Date: April 30th, 2026 12:09 PM Author: histrionic hateful roast beef dilemma Let's say Bob is 1 and Alice is 2. In this case she would immediately know her number
If Bob is 2 Alice can be 1 or 3. So she would not know her number. If she's 1, bob knows he is 2 (question is asked twice). If she's 3, bob does not know yet, but asks Alice again. Alice now knows she is not 1, which means she must be 3. So the question gets asked 3 times by the time she knows, and the higher person always knows first.
If Alice is 163 Bob is 162 or 164, but since Alice knew first she is higher. This means Bob is 162 and it's the 163rd time the q has been asked
This one is easier than the others I think because you can derive the pattern with no real tricks, but I'm not sure how to RIGOROUSLY prove it.
That's assuming they don't communicate a strategy, but I think that part is implied with the "perfect reasoner" bit (not sure why else it would be mentioned) |
|
Date: April 30th, 2026 3:40 PM Author: high-end private investor crackhouse You're right about Bob's number and the fact that Alice knew first because hers is higher. But the total number of Qs is wrong.

|
Date: April 30th, 2026 12:20 PM Author: Awkward Menage Psychic Alice could have seen her own reflection while you were making the phone call (setup doesn't explicitly forbid this). So when she says "Yes, my number is 163", it didn't follow from induction she just saw it. Then Bob’s number could be either 162 or 164, since the only constraint is that their numbers are consecutive positive integers.

|
Date: April 30th, 2026 5:49 PM Author: Irradiated carnelian address mad-dog skullcap i don't like this one, because "perfect reasoning" here doesn't mean a person applying human reasoning perfectly, which the format of the question gestures at, but rather a problem solving technique that doesn't map well to human reasoning at all.
midway through the exercise, bob will tell himself "now i know that alice knows that i know that alice knows that i know..." and so on, iterated n times. now this is not really a different cognitive state than n+1 or n-1 because human cognition doesn't work that way -- there is no experience of "knowing that knowing" at that level of depth the can be distinguished for one level up or down
so the question ends up being a fairly straightforward one about designing a recursive algorithm that is made more difficult by dressing it up as a story about people who must act not like people for it to work
