I sometimes think of this kind of puzzle as a "what's in my pocket" problem, after the scene in The Hobbit where Bilbo accidentally stumps Gollum with the riddle "What have I got in my pocket?" Like you said, there's an infinite family of solutions to any next-in-the-sequence question even when presented more formally, so only the asker can possibly know the "real" answer with certainty. This can feel unfair or unsatisfying even when the answer is eventually revealed, so it's no wonder that a lack of a clear solution agitates people who have gotten themselves invested in solving it. It seems that a lot of mathy people recognize "what's in my pocket" problems and dislike them. On the other hand, basically all traditional riddles are "what's in my pocket" problems at heart -- the whole point is to communicate with the person posing the riddle and try to decipher how their brain works, usually through some cute wordplay-filled clues they've given you. Obviously a lot of people like these riddles! They show up so much in culture and myth. The problem, I think, is that this kind of riddle has different expectations around it than a math riddle. With math riddles, you can pose them Martin Gardner-style where you find a fun problem, publish it with all ambiguity stripped out, and then let people chew on it for a month because once they have the answer they can usually verify it themselves. With traditional riddles, the asker and solver need to be in active dialogue so that the solver can be told when they have the right answer. This puzzle in the video has numbers and symbols in it, so people expect a math riddle, but really it's a traditional riddle that's been chopped in half.

I don't think you'd get people arguing that they know The One True Answer -- you only know you have The One True Answer if you tell it to the sphinx and she doesn't devour you. The social contract is just different around riddles like that.

God, Vi, you continue to be one of the most important and original voices on KZfaq. Thank you for this video. I can already see it going alongside "Twelve Threads" and "Suspend Your Disbelief" as one of my favorite video essays on online culture and politics. What you were talking about at the end there reminded me of the "irrationality of rationality," which is a concept I've been thinking about a lot lately since learning about it in another video about climate change. Like you said, our culture places a lot of importance on rationality (often in the guise of mathematic and scientific "truth") but the actual truth is that life is not a logic puzzle. The world is not a logic puzzle. And if we start to approach it like it is -- by, for example, over-relying on important-sounding statistics like GDP as an analog for happiness and societal progress -- we're going to make decisions that value this "rationality" (which, at the end of the day, is often just a cover for ideology and power) over the lived experience of actual human beings.

I think that that kind of rationality is misnamed, though. May it be called something like “logicality” to reflect an already usable relationship between “deep” and “deepity”. True rationality doesn’t concern itself with following a strict set of a priori rules, it concerns itself with consistently keeping your beliefs in check with reality and consistently achieving your goals given the hand you’re dealt-what Eliezer Yudkowsky metaphorically (but also pretty truthfully bluntly) called “winning”. But yeah, this is not a popular kind of understanding of what “rationality” means. But this is IMO the spirit of what people wanted for it to be, they just were wronger than we can be currently. I wish the world at large would get fixed about what it actually means. But that’s hard to do… 😞

I hadn’t thought of logic puzzles like that before. I tend to think of them not as a way to boost your ego and prove you’re right, but instead in a “puzzles are a fun way to challenge yourself, test your skills, and learn new things” kind of way. But there are so many different ways to look at them and I think people enjoy them for a huge variety of reasons. Another one some might have is “life has so many factors out of your control. Here’s something concrete” kind of way. I definitely am a 12 kind of thinker, but having you explain the 18 answer was really eye opening! I hadn’t even considered the possibility of not filling in the blanks of the missing numbers! Thinking about all of the possible answers out there waiting to be explained reminds me of the triangle problem where you name how many triangles there are. You have to twist your brain to see not just the ones that are obvious to you, but also look with a different perspective to see the ones that are hiding from you.

It's a brain thing, we feel good when we're right and bad when we're wrong, our brain does that automatically. Fun part is that the brain doesn't actually care if it's right or wrong, just if we believe it to be right or wrong, so ambiguous questions don't have the same effect. With something arbitrary, like what political side is the best, right or left, both answers can make you feel either good or bad depending on what you believe. You can take this to much more extremes too, if you can convince your identity structure that murder is the right thing to do then you can feel good from murder. Your entire mind, your identity, your world view, it's all like this, completely arbitrary. Because at the end of the day morality is not a real thing, it's something we've made up from an assumption that our life, human life, or life in general, has inherit meaning or value, something we have zero evidence for. Ultimately good and evil, right or wrong, this all comes from the simple experience of an animal feeling either pain or pleasure. Pain and pleasure comes from two separate parts of the brain, and these parts are what is activated when we're either right or wrong. So our brain responds to being wrong in the exact same way it responds to being punched, and to being right the same way it would respond to being kissed. This is all because our experience of pain and pleasure comes from adding vs substracting. When something is added to us, be it food, oxygen, affection, admiration, or an idea/belief, it feels good. When something is substracted from us we experience pain. If oxygen or food is substracted, pain. If affection is substracted, pain. If a body part or person is substracted, pain. If an idea that we had made part of our identity, personally or culturally, is substracted, pain. So any opinion that goes directly counter to our own is treated by the brain as an attack, something being substracted from what we consider self, and it will tell us we're in danger activating the fight or flight response. When this happens on a large scale, an entire culture telling another culture they're wrong, then we get wars. On a smaller scale we get divorces and people arguing on the internet. tldr: humans are stupid animals.

@@pinguino55h40 When there is an infinite family of solutions to 'best fit' data to a function, it is customary (in the fields of mathematics that work with such things), to ask if there is a *simplest* function that does so, by some definition. In this case, there are no order 0 or 1 polynomials that fit the data, and the (y = x^2 + x) function is the only order-2 polynomial that fits the data. So as the unique lowest-order solution, it gives us our 'answer', in the interpretation that there is such a thing as 'the answer' at all in a meaningful way. Since there are four data points, we know that the 'best fit' function should not have degree higher than 3; there will be an infinite family of degree 4 or higher functions that produce the given pairs, and that isn't useful. So our task is to see if there exists a unique function of degree three or lower that 'best fits' the data. That process spits out (y = x^2 + x) in this case. But of course, that is the 'it is customary in these fields' thing again - when coming from a particular direction, one carries with them all manner of conventions, methods, and perspectives that might or might not be relevant, depending on how a question is structured, which is ultimately the point. :)

​@@HeavyMetalMouse yeah I see that, however I guess what I was trying to illustrate is that these questions are so ambiguous because we don't have the full context, we don't know what the author meant. If this question was made by some drunk guy at the bar who does not have a degree in maths I doubt he would consider the 'best fit' standard definition you gave. But if this was made by some mathematician that studies this field then he is familiar with the conventions and he would probably mean that. Ultimately, for the general public we are left with a question with multiple valid answers since we don't know the full details of the problem. Even with not so complicated and specialized reasonings (such as those illustrated in the video) we get different answers such as 12 and 18, which is troubling. And even if we limit ourselves to our 'math brain' or 'programming brain', or any perspective we could look at it, there are still many more nuances within these fields than the question itself communicates, such as the fact that infinitely many polynomials pass through those points, or functions for that matter. The question itself also fails to teach those nuances which is why I think it is a poor attempt at teaching maths if this question is just thrown out there in a 10 second short or tiktok that just says 'guess the correct answers guysss!' and does not elaborate further. Instead we should explore all the possibilities to teach that in maths there is always more than meets the eye in the beginning and that is one of the reasons why maths is very rigorous and specific.

I think the point is actually mistaken though, at least the way it was presented here. Putting reason and rationality above all else is not a choice. It is the foundation of anything else you do and how you set your other priorities. You can choose to lie to someone to be kind instead of telling them the truth, but that requires you to use reason to decide that that is the "right" choice under your system of ethics, regardless of what your system of ethics is. This "problem" a good example of how reasonable people can disagree when working with different assumptions and that real life is under-determined and there is no "right" answer. However, regardless of the approach you use, you have to be using logic and reason to reach your conclusion, and you need logic and reason to be able to explain to yourself and to others what assumptions you are making. If you said you were using programming logic or you were using pure maths logic and you got the answer of 3-4i, then you made a mistake in applying your system. You are objectively wrong about the conclusion you made because the conclusion you reached based on your stated assumptions and methods was not consistent with the answer you came up with. The only way you can check if your conclusion is correct based on your methods and assumptions is reason and logic. That kind of mistake would usually be caused by something that in programming would be detected by a unit test. It is important to stress test your assumptions and methods to make sure that your conclusions that you expect match what you actually would like them to be. This is similar to a functional test in programming. You don't want your ethical system to tell you that the answer to the trolley problem is to run over one person and then back up and run over the five people on the other track, as an extreme example. But to do that you need reason and logic. Proof by contradiction is also another example of where reason and logic have to be placed on the first step of any attempt at ethics. If you are evaluating an ethical framework, when you reach a state of contradiction, you know that modifications must be made either to the assumptions or to the methods.

So didn't go to formulae or standalone algorithms (despite beeing an old software engineer!), I just looked at the differences down the sequence (18, 16, 14, ...), then the differences of differences (2, 2, 2, ...) which looks tidy enough to me so a good enough answer that yielded 12. I suspect that's due to early puzzle training for the "11+" test we used to do in the UK between junior and senior school to segregate kids between Grammar schools and Secondary schools...

On the other hand, it is not an objectively bad thing to want to be accurate and meaningful in your communication. We don't need to abandon this instinct necessarily - we simply need to find a better way to frame it socially when presenting it. When a friend is supporting their position with bad information, even if their position is right or good, it can be a good thing to correct that bad information, so that they can use better, good information, to support their position - but if we present it as "You are wrong about this." then that won't come through and we'll just look like the arse again. :/ Presentation and context are important in delivering information, which is also easy to forget. - Sincerely, someone who also has a lot of problems with this stuff.

Valueing a person as a human being does not mean believing everything they say. Like imagine you had a close friend who was a flat earther. You care for them. You have parties together.

@Vihart
@Vihart Жыл бұрын
I didn't go into this in the video, but your flat earther is a good hypothetical to make this distinction: generally my position is that while of course you don't have to believe what someone else believes, it's usually best to assume that something they tell you about their own experience and own life is true. Like, if you party with your male flat earther friend, and the next day they tell you that they got jumped on their walk home from the club later that night, it would be weird not to believe them. "Believe women" is a slogan that acknowledges how commonly women experience that if they talk about their assault, people feel justified in not believing them or defaulting to suspicion until proven otherwise. Many women do not get care, or help, or invited to parties anymore, by the people in their lives that take the side of their abuser. I guess I could've put all this into the video and made it even longer, but probably more on theme to have 2-way communication in the comments, so thanks for writing in.

At first I'd tried looking at the relationship between the numbers on the right (90, 72, 56, 42, ?) and thought it had something to do with multiples of 8 (90-8 =72, 72-16 = 56, 56-24 = 42), which lead me to ? = 10. On looking at it again you can see where my brain made some subtraction mistakes, which definitely threw my theory off😅 it seems even on a question with no right answer i still picked the wrong one. But on another point, I love how you talked about the different ways of thinking about the problem, either from a mathematician's perspective or a programmers perspective, or leaving the rest open to a different kind of interpretation. These kinds of questions as you pointed out don't really have any intent (unless we learn it from the creator) other than to get people talking or stir up arguments and the like. Who is right, who is wrong, what's the *true* answer. But you take the time to step back and see how people came to these different conclusions. And it's awesome! It's an invaluable skill in comprehension, moderating discussions, understanding how and why people come to the conclusions they do.

Ahhh, love Vi. I am definitely one of those people that has (in the past, hopefully less so in the future) valued my own logical reasoning over maybe being kind or at least, just listening. Sometimes it is REALLY difficult though.

Knowing that your own logical reasoning is only one way of looking at things is a good first step. However the second step that Vi dismissed was applying the other person's logic and seeing if it makes sense. You don't need to ditch logic and reason to fully hear other views, and you still need to see if other people have a logically sound answer or not. Putting reason and rationality above all else is not a choice. It is the foundation of anything else you do and how you set your other priorities. You can choose to lie to someone to be kind instead of telling them the truth, but that requires you to use reason to decide that that is the "right" choice under your system of ethics, regardless of what your system of ethics is. This "problem" a good example of how reasonable people can disagree when working with different assumptions and that real life is under-determined and there is no "right" answer. However, regardless of the approach you use, you have to be using logic and reason to reach your conclusion, and you need logic and reason to be able to explain to yourself and to others what assumptions you are making. If you said you were using programming logic or you were using pure maths logic and you got the answer of 3-4i, then you made a mistake in applying your system. You are objectively wrong about the conclusion you made because the conclusion you reached based on your stated assumptions and methods was not consistent with the answer you came up with. The only way you can check if your conclusion is correct based on your methods and assumptions is reason and logic. That kind of mistake would usually be caused by something that in programming would be detected by a unit test. It is important to stress test your assumptions and methods to make sure that your conclusions that you expect match what you actually would like them to be. This is similar to a functional test in programming. You don't want your ethical system to tell you that the answer to the trolley problem is to run over one person and then back up and run over the five people on the other track, as an extreme example. But to do that you need reason and logic. Proof by contradiction is also another example of where reason and logic have to be placed on the first step of any attempt at ethics. If you are evaluating an ethical framework, when you reach a state of contradiction, you know that modifications must be made either to the assumptions or to the methods.

(What I thought of before watching the video:) 3 = 12 Method: Subtracting n from n’s value on the right results in n • n. This means that to find the value of n, the formula is n • n + n, so 3 would be 3 • 3 + 3, resulting in 12. ((Generally you’d write the formula as n squared + n, but that’s harder to write digitally here) Clarifying: not what I think is the solution, there obviously isn’t just one, just thought it was interesting, and that it was funny that apparently I’m the only one to think n squared + 1 instead of n(n+1)
