Everything in the video is worded wrong, the rule should be: "If the card has a vowel on the side showed to you, it must have an even number on the other side" Worded as it is in the video EVERY card should logically turned over to confirm that the poorly worded rule is not broken. I don't care how "logic" one is if they can't even understand the importance of the clarity when explaining the rules of a game.

This video is all about expaining logic, yet it's confusing as fuck

I said to turn over all of them. But I have trust issues.

"How do we know that all tigers have stripes?" At this point, there's so few, we could just check them all.

You never distinguished that "one side" is ONLY the side shown and "other side" is ONLY the one hidden. That is why people slip up. And it's cheap because it's a simply lack of information.

Anybody else come here because it was recommended to you, even though it was posted a year ago?

This was so good! I got caught by the A2 trap and now all I wanna do is learn how to think logically

i thought AK27 was supposed to be AK47

Who else read it as ak47??

Well maybe if people could understand the question, we'd be able to answer correctly.

I'm in the 4% but I used the wag system, wild assed guess.

4% correct because the wording of the question absolutely sucks. The fault is the test itself.

I definitely said "tiger" way too many times in this video... It took me ages to finally decide on "All tigers have stripes" as my example. I have seen a few news articles of a "tiger with no stripes" and if you type that into Google Images you will get some results... but if you actually look at the pictures, none of them are genuinely stripe-less. They either have stripes on their face or tail. But anyway, even if it turned out there were a tiger (or even a species of tiger) with no stripes... that kind of just goes with what I was saying, that we cannot know anything with 100% certainty. That being said... just because the possibility exists that something is wrong, is no reason to reject scientific research. Just because something is possible, doesn't mean it's ever going to happen. It's possible that Vladimir Putin himself could come to your door and say that he wants to watch How I Met Your Mother on Netflix with you. It's possible, it's just never going to happen. All I'm saying is... just because the possibility of something happening exists, doesn't mean it ever will. Just because there is the possibility that any given scientific research is wrong, doesn't mean it's even remotely likely.

I was so confused about the cards until you showed they were double-sided.

My logic is correct, this test must be false. therefore, if this test is false, then my logic is correct. 4.6k people must have been thought that.

I didn't understand why I got Wason wrong until I saw this. Now it makes sense. I still think the wording of Wason is confusing though as I thought you were looking for a fault in the card printing machine..

The wording of the first question is the reason that people pick the wrong answer

I must have missed the part when the cards had shit on the opposite side. The information and instructions werent clear. Had nothing to do with "logic," but how you explained it.

"Logic is the beginning of wisdom, Valeris, not the end."

Funny how immediately obvious it became with the real world example, yet I utterly failed to comprehend the first version. I would've said all cards. I think an inherent problem with puzzles like this is, especially when worded as "How Logical Are You?", is that they put people on the spot. What goes through their heads is "if I don't get this right, I'm dumb." It creates pressure and makes people lock up, kind of like someone having to perform a piece for an audience or holding a presentation. Therefore, they might not be able to think clearly.

I hate this test. It is fundamentally flawed. The correct answer is A, K, & 7. A & 7 are explained in this video. K must be turned over because it could have a vowel on the other side. ...but wait, we established that all cards have numbers on one side and letters on the other, right? No, they asserted that all cards have numbers on one side and letters on the other. In order to confirm that, we must turn over the K. If it has a vowel on the other side, the rule has been falsified. This may seem like a trivial critique, but this failure in logic is at the heart of most invalid scientific experiments. People make assumptions about which variables matter, and suddenly their "control" group is invalid because they haven't accounted for a variable (usually several variables) because of their innate biased assumptions.

This first example was just worded badly, not illogical reasoning, just extremely poor wording that encourages wrong answers.

More videos like this please. This is more academically useful than trivial videos about flags or calendars.

I actually got it right? Cool. I really enjoy these kind of elimination-oriented logical puzzles. Please post more! 👍

This isn't "how logical are you?" it's more like "Choose 2 out of 4, solution"

Yay, I belong to the 4 percent! I now demand special tax breaks!

Here's a very simple way of explaining this test. The point is to put aside the tiles which are IRRELEVANT to the rule. As in, it matters NOT what is on the other side, because either way it will not break the rule. K is put aside because K is a consonant, and there is no mention of consonants in the rule. 2 is put aside because the rule states "If the letter is a vowel, the other side must be an even number" yet it does NOT state that an even number must necessarily have a vowel on it's flip-side. A and 7 are the correct choices because what lies on the other side of those tiles can, in fact, determine whether the given rule is upheld or it is not.

I cannot beleive this video has 4k dislikes. That's four-thousand people who, even after having this explained to them in detail, still exhibit the cognitive incompetence as to not understand this fairly simple concept. I think this video is amazing. It genuinely changed my way of thinking. I chose "A" and "2" my first time through. My mind illogically inferred the "Q → P" situation. This revolution is staggering. I can genuinely apply this new knowledge to my life. For example, there is a video that talks about the "Logical Paradox" that is created by inductive reasoning. But, I feel that they have broken a rule by calling it a paradox. If your premise is "All questions derived from a situation without any perceivable answer are a paradox."... then the rules apply. Where 'P' is "Question with no perceivable answer" and 'Q' is "Paradox". Saying "It contains a question that has no answer, ergo, it must be a paradox"... would technically be valid. It feels wrong to me. Perhaps their premise is wrong? What do you guys think?

Am I really part of the %4? I hit my shoulder on the corners in my own house. It's hard to believe that I'm on the positive side of anything logical.

You should do a videos about the situations in Tibet, Kurdistan, and Kosovo.

I don't see how the question was frased badly. I didn't get it first, but know it's completely clear: All other combinations follow the rule, except vowel on the other side and odd number on the other (or vice versa). First you check that there is no odd number behind the A and then that there is no vowel behind the 7.

I feel as though half of these comments belong on r/iamverysmart

The question was explained perfectly you just need to pay close attention.

I got it wrong because instructions were not clear

Where was this video when I was failing my logic class during the fall semester 😩 you made it so much simpler

Great video! The question of the survey was bad though. There were multiple times when I thought I understood the rule and realized I actually didn't before the tiger explanation.

Oh man, Kerbal Space Program music. I can't concentrate xD

This video shows 3 types of people: 1. people who got the question right 2. people who got the question wrong 3. people who blame the question and video uploader

We can also invert both rules, but both statements must be negated, so the inverted first rule could be “If there isn't an even number on one side, there mustn't be a vowel on the opposite side”. The real life example's rule can be inverted into “If a person isn't older than 18 years, they mustn't be drinking alcohol”.

My first thought was: turn over all 4, to check if they've all followed the rule. Changed my mind to: turn over A and 2, since only vowels and even numbers matter. Thought about the wording of the question some more. Decided that A is the starting point, but it does not actually say it could go the other way around. Changed my answer to: turn over A and 7. I changed my mind so many times I thought I must have them all wrong😆

to determine if the rule has been completely followd u shoud have to turn over all cards ...

Im here because of Kerbal Space Program music.

I thought the vowel card think meant vowel on one side (A) and the opposite side(7) the opposite side of the row.

I got it right but the question wasn't that clear

The first one was worded wrong I think - Instead of "one side" and "other side" it should be "THIS side" and "other side". That confirms that the rule only applies to THIS side. "One" side could mean EITHER side!!! At least in the form of English I speak...

I got it right, but not using reasoning. I guessed randomly

Wow great video! I learned something today! And the topic was actually interesting and I understood it! Go learning! ....unlike in school instructions were pretty clear... lolz

can everyone stop saying the wording was bad. sure it wasn't perfect but you can understand it. Also, it doesn't matter. it literally makes no difference and the fact that you are getting angry because you are normal makes you salty and unable to accept that you were wrong. he is not calling you stupid, he is explaining something extremely well. If you don't like it, don't watch it. Don't hate, there's no point.

The legal age of alcohol drinking is 18? What country are you filming this from?

The comments are full of people who haven't accepted they got it wrong and are instead coming up with excuses for why their 'logical' brains didn't figure it out.

Instructions were totally clear, I just got it wrong because I'm dumb

they left out the information that if there's a letter on one side there has to be a number on the other and vise versa

What does it mean if I chose to open all the cards? xD I wonder how many people chose that option?

Is this music from Kerbal Space Program?

Anyone notice it's the Kerbal space program music playing in the background??

Only 4% got this? I don´t think democracy is a good idea then.

why do I wanna play KSP

Big fan of your videos with their outstanding production quality. Keep up the great work.

Real question though. Is this gonna help me with decision making and interpersonal conflicts?

People raging in the comment section because they don't have basic interpretation skills

All hentai is anime but not all anime is hentai. Am I doing this right?

kerbal space program

Thanks, I learned something new that I enjoyed learning.

I love when people say "Nahh unclear those are two sided cards.". I'm curious to know how they interpreted: "it must have on the other side" and "turned over" at the end ... "it" may refer to the subject, and there is only one here: "a card", thus "it" means this particular card, making it pretty clear that cards have two sides. Ok, lets pretend there is another way to interpret this (even though I don't know which one), when you now read "turned over" this means that something (I'll pretend I still don't know what) have two sides. Now, what is the subject of this sentence, ohhh, it's "card(s)" hmm, maybe we need to turn over card(s), which would mean they (all) have two sides.

Oops! Looks like Peter Wason did not get his statement worded correctly.

My teacher asked us a question similar to this in my computer science course to explain to us computer logic. She had a hard time explaining and I had hard time understanding but you made it very clear and easy to understand. Really good real world examples too. Thank you! :D

I can hear music that's in KSP in the background of this and I was just playing it.

I was one of the people who got the "sides" thing mixed up. I didn't pay attention in the slightest to what he was saying and only read the question. A K 2 7, when i read "pick which cards should be turned over" I thought the question was asking me "which card(s) do you need to flip over to make sure the set of 4 are following the rule". I thought to myself "if I flip 7 it might be an even number" then you would work with the 2 on the inside k, and 2. so you would flip k and it might be a vowel. Then I read some comments and found out that was not what the question was asking me. To say that sides can't be misunderstood and that the instructions were perfectly clear, well I highly disagree. However, I don't blame question maker, the question does have information to solve it correctly. If I blame anything, it would be the English language. Once that is clarified I have no problem with the test. I also disagree with people saying that assumptions are not logical. The statement may be correct but I think people are confusing assumption with "Hypothesis". Another flaw with language. The scientific method is as such: Ask a Question Do Background Research Construct a "Hypothesis" Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Hypothesis - a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Supposition - an uncertain belief To say that making a hypothesis is not logical is saying that all scientist are not logical.

bull. the only way to test is to turn ALL FOUR. You start with the premise that the "rule" could possibly be violated. What if the backside of the K has an "E"? Then it violates the rule of "vowel one side, must be even number on other side" . Now, if you had BOTHERED to actually list ALL the rules that apply at the same time, then you might have a case. But you state an INCOMPLETE problem, then get on your high horse and pretend that you know what is going on?

4% ignore semantic ambiguity, and correctly answer through arbitrary paranoid suspicion. The cards have two sides. Both sides are the other side to one side and so some referencing to original orientation would clear the semantic ambiguity ignored by 4%

So many people complaining about the instructions, but THATS THE POINT! It is to see how logical you are going to think about it.

If a = b then b = a ( True) If a -> b then b -> a(False) Where ( = ) is equal to and ( -> ) results in/causes Easier explanation for the people that didn't get it If round =(is) circle , then circle =(is) round (True) if Toxic Gas ->(causes) Suffocation ; then Suffocation ->(causes) Toxic Gas is obviously False In the question above we are given that a card with a vowel causes an even number on the other side of the same card Or you can tell me that I am wrong and that all stripes have tigers .....

"If a card has a vowel on ONE side" made me think I had to flip 2 to check if there was a vowel or not. I thought ONE counted for both sides of the card. Therefor A, 2 and 7. It could have been worded better. Like "If a card has a vowel facing up" etc

Whenever I do these, it's not that the wording makes my mind think the wrong answer, it's that I can't understand the damn question xD

In the original test it specifies that the card has a "Side-A, and a side-B" Which is so important in understanding that the rule doesn't go both ways. The way you explained it rendered the entire test completely illogical and redundant.

Nice bit at the end about just because we can't be absolutely certain about something doesn't mean that it should be open for debate. Just because I can't prove that every single tiger has stripes doesn't mean that tigers don't have stripes, it's up to the other person to prove that they don't. Likewise it's up to people to prove that dinosaurs, evolution and climate change aren't real, which they can't

After 3 minutes of listening, I finally get the rules. I was looking at the cards as being two different stacks, and "If a card has a vowel on one side, it must have an even number on the other side" as being *left* or *right* of the (unknown) card in the middle. So I assumed all the cards would be turned over (showing a similar card backing) and it was the order of the cards that needed to be checked. Poor wording of the rules, in my opinion.

i got it wrong because the question was phrased badly. i didnt know if it was mirror sided or not. mirror sided being a and 7 and it not being a and 2

Actually the wording of the first question ISN'T incorrect. I thought that at first too, but after thinking about it for a while I realised it was not the case. All the rule said was that vowels had to have even numbers on the other side. It never said that consonants had to have odd numbers. It didn't say anything about the consonants. Therefore, if you see a 2 and you turn it over to find a B, that isn't necessarily breaking the rule because the rule never said that the consonants couldn't have even numbers as well. However, if you turned over the 7 and found an E that would break the rule because, as a vowel, the E must have an even number on the other side. That's why it's the 7 not the 2 and that's why the wording actually isn't incorrect at all. It has nothing to do with which side is facing up or down.

The test will be much clearer and easier if it also stipulated (in written - on the same screen we see the four cards and the text of the question) that "All cards have letters on one side and numbers on the other side". I know he says it in the beginning of the video, but people may skip intro or don't pay attention until they see the actual wording of the question. If you see just the wording on the screen - it is correct to assume that 'K' must be turned over as well, since there could be a vowel on its other side.

surely the best answer would be to turn over all the cards

I like tigers.

I would say the K card needs to be turned over as well because it could have an A on the other side, which would invalidate the rule.

Defining "side" would help. Front side and back side for instance. There is also left side and right side. I assumed the later and that required me flipping over the seven making it A K 2 which has a vowel on the left side, and an even number on the right side.

well the only reason we may have messed up was because you didn't explain that the cards were double sided. i for one believed that the problem asked how many cards you would have HAD to flip over to figure out the question from a point in which you could not tell which cards were which.

For all these people that say he stuffed it up by not saying that it must be the shown side, you are wrong. He said it right. If the rule was: If the shown face of the card has a Vowel, then the hidden face MUST have a even number. NOT the other way around. Which means if the seven had a consonant, Good, and if it had a vowel, then it doesn't matter because it is not the shown face. In this case the only card you need to prove this rule works, is the A card. This is because it makes the 7 card irrelevant, as mentioned earlier. He said, that the rule says: If any face of the card has a Vowel, then the other side must be an Even number. This way DOES work, unlike what most people seem to think. If the seven has a Vowel, then you have a contradiction, that is resolved by saying that the rule does not apply to these cards. If it is not a vowel, then good the rule works.

This is so interesting, it's just like trying to see how intelligent an animal is. We are subject to the same kind of limitations based on what we are familiar in a way.

holy crap it looks like I'm part of the 4% I actually got this right! :)

How am I supposed to reason correctly if I don't even understand the question? The question is very poorly phrased/unclear in my opinion (there's way too many possible interpretations of it), and I'm not surprised so many people got it "wrong" if it was phrased like that. Could someone please rephrase the question clearly?

I would've chosen the AK-47.

First time I've seen ToK content on KZfaq 👌👌

I agree they didn't show the whole question but I still got it right //feels special

Anyone who ever did even middle school level logic or programming couldn't possibly fail this. The only "trick" is that some people automatically assume "if any only if"(↔) from "if"(→). If you break down if into not(A and notB) you can't fail.

The rules do not state, If a card has an odd number on one side, it must have a consonant on the other side, or vice-versa either. So flipping the 7 does not verify anything. Same with the K or the 2. The rule is "vowel", "must have", "even number" and does not state even number must have a vowel, consonant must have odd number or odd number must have consonant. Only the "A" can verify the rule is being followed. Are you explaining it wrong? Were there more rules that you failed to show us?

EASILY..The Best Video Ever. Periodtttt

Lots of people saying the question wasn't phrased very well. The question is perfectly fine, all the information you need is there. 'If Vowel, then Even', it can't be simpler. It makes no rules for consonants or odd numbers and so none should be assumed. For some reason, people need that to be explicitly stated in the question, well that's where your logic should come in.

I'm a computer scientist so this type of logic is my life

Kerbal Space Program background music. props m8

if we share the same understanding of the work "card" then it is safe to assume that if we flip a card twice we will see the same num/let again. with the assumption A and 2 are to check because the others dont matter. that would add another relation: "P --> Q" stands here for Q is backside from P. with the assumption above: P --> Q Q --> P

Ayyyee I remember watching this in Geometry class :D It took me quite a while to get all this logic stuff
