re. "contract cheating": teaching English in Japan, I've had two students I know for sure use(d) machine translation to do their homework. I'm not working in a school or college; there are no grades or tests-these people pay me to teach them how to speak English because they want to learn to speak English. this makes no sense to me, at all.
Massive cultural anxiety around failure seems like a plausible explanation. When I was in japan there were police in schools and dorms around exam time because suicide rates skyrocketed. Even if grade pressure isn't there, the feeling that not doing perfectly on any one task dooms you to failure forever can be hard to shake
@@stephenchurch1784 not impossible; there's not really anything to fail at, though. I think for the current one, who's (semi-)retired, that he does it because he really wants to talk about big important (to him) topics, and he wouldn't be able to approach those topics without writing it in Japanese first and then using automated translation. one problem is that the way he writes in Japanese is extra hard for the software to translate-he never uses an easy, clear word when a difficult, ambiguous one will do, for example-so it's really hard for me to understand what he means a lot of the time.
Q1: Did you pay someone to complete your homework? A: No (truth) Q2: What percentage do you think have paid someone to do their homework? A: 95% (also truth) Q3: How can this be? A: In a class of 20 students, I was the one getting paid.
Negl I actually have gotten paid to do homework for classes that I wasn't even in... Should I feel bad, probably, but do I feel bad, no... (It was for a computer science class that some med students were taking, and they just couldn't grasp the concept of a loop even after spending a couple hours trying to explain)
@@Emily-fm7pt Wait they didn't grasp the concept of loops... Like while and for loops? How the hell did they pass kindergarten? How much of an NPC can one be. They all have 2 brain cells fighting for 3rd place.
For this to work, the students have to make the calculations described in the video, but if they are cheating to pass the class, they will not have learned enough for them to be able to take all of the available information into account correctly
There is a difference of sensitivity and interpretations of actions too. With lot of grey area around collaboration vs copying, tutoring vs homework help vs contract cheating it’s blurry but reliable that a wide majority of people overestimate themselves self identifying as above average (good, honest, smart, kind, whatever) when that’s highly unlikely and many are below average.
I think it is more generally for a population. It won't prove 1 person is lying, but it can be a pretty good rough approximation for what percentage of students are cheating.
People cheat on tests by glancing at your paper. One of my professors used to give tests in a large room and naked everyone separate two desks away from each other. You should have been there to hear the grumbling. Lol
I thought this was going to be the trick where the survey has you flipping a coin, where if it's heads you always answer "yes you cheated" and if it's tails you answer truthfully. But this is even more interesting!
It seems that the implication is that "telling the truth" usually means "confessing". If people think they are being rewarded to answer as though they are cheating, then how many will do that even if they are not cheating?
Maybe I'm missing the point but wouldn't this encourage the students to contribute as much as possible to a high iscore, i.e. by ticking "Yes, I cheated" and guessing that 0% cheated? I do see that people who are in fact cheating has something to win on telling the truth, but doesn't it make people who didn't cheat more likely to lie?
I've got nothing to back this up but I have a feeling that there is some correlation between academic integrity and propensity to lie on a survey. I doubt it's a one-to-one correlation but the situations are both tests of integrity
I thought the exact same thing, but I realized, the iscore for a yes answer would increase, but the frequency of ticking no and the probability guessed of people ticking no can also be used to create an iscore. This iscore would drop by doing this
Not clear but maybe your iscore is based on your answer on whether you personally cheated. I.e., if you say you did not cheat, iscore measures positive surprise of percentage who didn’t admit cheating vs percent you expected to not cheat. One thing he doesn’t address is survey size. If there is a large survey, your confession is going to have a minimal impact on the iscore.The whole Bayesian survey design might still have predictive value because of the effect he describes of believing most people are like you, but large survey size will dilute the incentive to be truthful.
This is awesome. I am an undergraduate student who participated in the study. One of the writers is my lecturer. It is very interesting to see this explanation!
So, I’ve written many papers for peers but have never myself cheated on any assignment. That raises my prediction of cheating frequency and confounds the “serum.” Perhaps it would be better if I were asked if I’d “participated” in contract cheating, to which I’d answer yes. Or, to put it another way- I believe that many people cheat but I don’t cheat myself. So, how should I answer the questions to best earn the money? Should I lie and say that I do cheat in order to get closer to the mean values, or should I use Bayes’s theorem to update my beliefs on how likely people are to answer the first question affirmatively? It’s an interesting question if you consider the problem from the outlier of someone who’s facilitating the cheating but not cheating on their own work.
This is the perfect time for this video for me. I am currently learning discrete math and I love seeing real world examples of it! Keep up the great work, Professor!
@@idontwantahandlethough Oh i know ways, all their conventional ways are ineffective and the only types of research that would yield somewhat useable data is unethical and would not pass ethics committee, best they can do is what they are doing using flimsily barely proven concepts and pile their barely provable hypothesis on top of those flimsily barely proven concepts. Even Bayesian Truth Serum has gaping holes, you cant statistically account for maliciousness because malicious people are by their nature unpredictable, all you can do is construct a rigid narrative and compare everything to it but by that point you are no longer dealing with science but with religion or a cult, which is where i see psychology at, although i have to say honor to the exceptions however there are few of those.
@@lordhater4207 most sciences have their unknowables. It's like saying physics wasn't a science before we observed light's properties as a wave and a particle or before we proved quarks and stuff or before we figured out gravity (oh wait, we didn't really yet, i guess physics must not be a science)
@@blahybris608 Yea i know psychologists like to compare themselves to physicists or mathematicians however that's like comparing apples with anvils, physics is a WELL very WELL defined science because it's research is limited to physical realm be it infinitesimally small or incomprehensibly large it's still within physical realm, physics can be wrong about their hypothesis however if a hypothesis is wrong only that hypothesis is wrong and perhaps its branch. I like to use reverse engineering as an example, physicists can see memory of the system (nature) and corresponding values of STATIC memory addresses point (both discovered and undiscovered laws in physics) at they assume how background processes (that which they can't see or understand by observation alone) produce values they see those STATIC address point at ,and test it out, when and if they are wrong it's not the fault with STATIC address but of their assumption, they can backtrack what they did wrong since subject of their study is static and so they can simply pick themselves up and start over having learned even in failure since their fail may just be data type and not wrong assumption, however physicist cannot CHANGE variables because if that were true then we could turn gravity off, physicist is not in control of nature it's just its scribe it's documentor and observer, this isn't true when it comes to psychology psychologists may see memory of the system (human) however their problems are way more complex than the one physicists have all due to a fact that their memory addresses aren't static they are dynamic as in they change due to all sorts of reasons from subject of their study (humans themselves) to the methodology used to uncover background processes (research) that when they are wrong and they often are cannot even bactrack what went wrong because by the time they do address had changed and they don't know if it is environment, is it the subject , is it methodology in other words psychologists due to the research can and do change variables and can influence outcomes, this doesn't happen in mathematics or physics and since it's simpler when compared to psychology they can do some really impressive stuff with it some highly complex experiments and still be valid because subject they study is static, whereas what psychology would do with complex experiments is only introduce yet another point of failure, thus is the reason why they limit themselves on questionnaire "research".
Well, if a question such as, “What percentage of people do I think have cheated on a test?” or something like that, I usually answer somewhere over 50% because while I never cheat on any of my tests, I am aware that people do cheat. These usually come from rumors of instances of students paying people to write their essays or buys answers of test questions, etc. Prior to all this, I seriously didn’t think people who pay up to cheat because the consequences were quite severe if you were caught cheating. It scares the crap out of me and so there was no way I thought people will still cheat considering the consequences.
In my school the professors say im supposed to just copy from those that know...and use that as the learning process. Apparently, homework is supposed to always be a social event. Wheras exams are not.
Really great video! One question that might want to be added is if that person *knows* if another person cheats. If a person who doesn't cheat, but knows another person cheated, will assume that most people cheated and be marked a cheater in this test.
I remember a take-home exam in college where nearly two-thirds of the students in the class worked together on it, despite *signing their name on the first page of the test to say that they would not use outside help*. They got caught (prof said they all used some weird notation that wasn't taught in class), and each received 0 points on an exam worth a solid 20% of their final grade. The heuristic in this video would probably mis-categorize me, because I've never cheated but I'm now convinced that pretty much everyone else regularly does.
I'd need to read the original article and the reviewers' comments, but off the top of my head, if you financially incentivise people to give surprising answers, you will get surprising answers. Suppose I didn't cheat, but I want to maximize my iscore so as to get as much money as possible from the experiment. I could answer that I do cheat, thinking that as a rare thing that people will predict to be rare, my answering this will nudge up the iscore for it. More, I could guess that others might have the same rationale, boosting it further! This, whereas on a survey with no incentives I would likely answer truthfully that I didn't cheat. This creates a biasing of the responses. So great, they get a result with a much higher percentage of cheaters than before - but how do they know those results are more truthful than the standard survey? Again, I'd need to read the paper, but I'd argue that they can't know that.
"More, I could guess that others might have the same rationale, boosting it further!" Guessing that most people have this level of meta-thinking would be irrational. You can look at past studies of this kind and see how many people act GT-optimal or adjacent, and how many just do what seems prima facie correct. It's actually ironic, because you are engaging in literally the same bias relevant to the bayesian truth serum. It's an example of "You are more likely to believe X is common, if you do it yourself." but with the variable X being equal to "thinking at multiple metalevels" rather than equal to "cheating".
@@tudornaconecinii3609 I didn't say "most" - I said "some". Assuming I would be the only one to think of it would be irrational in itself. Either way, whether I am overestimating the portion of people who would game the system or not, so long as it is not zero this would still produce a bias - rather than produce more truthful results. Glancing at the research, it seems they did try to control for such effects, so I'm not that far off the mark. However, I haven't yet read the whole thing.
@@Polymeron Your overestimation of the number of people gaming the system is directly relevant to your instrumental goals here, since it skews your answer to the second question, which results in you getting less money. I'm not proposing that you assume you'd be the only one to think it. I'm proposing precisely what I proposed: namely, to look at past studies of this kind and see how many people act GT-optimal or adjacent, and how many just do what seems prima facie correct. Because knowing to what extent people are superficial thinkers will directly boost your accuracy in answering questions of the second kind.
@@tudornaconecinii3609 It still seems irrelevant. First, If my estimation of people's estimation for the question is very low, then just my lying alone should make the surprising result more common than expected. Secondly, my point was specifically that people being encouraged to write surprising results, can introduce a bias - rather than only eliminate an existing bias. You can't both say that people will not act rationally and thus there will not be a biasing effect, and *at the same time* claim that the introduction of the incentive *will* have an effect because it changes people's behaviour as they try to maximize their gains. (Note how neither point hinges on my throwaway comment that an actor thinking of lying may further consider others doing the same as further incentive to lie)
@@Polymeron "(Note how neither point hinges on my throwaway comment that an actor thinking of lying may further consider others doing the same as further incentive to lie)" I am aware of that. I am not saying "I think you're wrong on this particular point, which breaks down your overall argument". I am saying "I think you're wrong on this particular point, full stop." I agree with your overall argument. I just didn't think of mentioning that.
Truth be told I rarely thought that individuals cheated until I talked to a professor and over heard a conversation of students who did cheat. I am appalled that some students do cheat on stuff
Oh boi, do a whole 10% of people ACTUALLY pay others to do their homework for them? I'd have guessed 1 or 2 percent... people with more money than brains.
What if a genuine person thinks many other people would cheat on the same difficult exam? Isn't this survey biased to only assume that genuine/not genuine people would think other being genuine/not genuine?
My guess was based on two factors who would cheat if given the chance 40% the amount that actually would go for it would greatly depend on perceived difficulty and consequences about 20%
2:01 as someone whos taken statistics courses... That second question is flawed. You have to always put in a neutral or "i dont know" type of option, or else your survey is unreliable.
In exams there were always those who went to the toilet a few times. Seriously, I don’t believe they needed to go,and were looking at information in private. Although I’ve never cheated my observations would make my estimation of cheaters quite high.
I'm not sure I buy it. This is based on a cognitive bias. Does everyone have that cognitive bias? If so, is it to the same degree? (I don't have answers to either question but I suspect the answers are: Yes, and almost certainly not). If we can't assume that everyone has the bias or that it isn't to the same degree the numbers become a minefield of best guesses. Perhaps they are accurate, but perhaps they are not. In any case, very interesting video.
Also, the bias depends on the environment. For example, even though I didn't cheat, many of my schoolmates did, or at least were planning to. So, my bias would be in an opposite direction.
@@Yorick257 exactly as you say. From viewing my peers throughout HS I would have said 50% cheat. The question would also have to be more specific, what defines cheating in my mind is probably different than other people.
Did you finish the video? He tackles this at the end, at 9:38. While it's impossible to identify individual cheaters, the methods here are still useful to make predictions about a population. Variation can and will exist, but in statistics you usually fight variation with large sample sizes and some math.
@@Palozon Yes, there will be variation. How much? You need to know that in order to deal with how it affects the numbers. Even taking a sample size of a billion would be useless unless you knew what the variation was.
@@SlimThrull I didn’t watch the video, frankly because I’m more interested in the psychological side than the mathematics of cheating, so I don’t know what method he is using. However, if he is using inferential statistics, then we can use various methods (which you would know about if you’ve taken statistics classes) to find the variation.
Your team did the study? I have a question for you if you have a moment. Did your team assume that the cognitive bias was the same for everyone? Since different biases affect people in different ways, it make sense (to me anyway) that a single bias might be more or less likely in a person rather than the next person. If that's the case, how did you adjust for that in the study?
You can also add more questions like this but where the answer is more obvious to get a sense of if this person is a higher chance of lying in general than others.
I just found your channel one week ago... I've been binge watching every single video you uploaded, you have a great energy when explaining things, I love it! Could you share the doi/title of the paper you were analyzing?
What if ~90% of the class cheated, and the 10% who didn't cheat get a bad score on the survey? How would you identify the group that cheated (good survey scorers) from the bad scorers, or is it an assumption that the majority is the one that doesn't cheat Great video, fascinates me actually. Subscribed right away!
Thanks for the sub! In that scenario, those who didn't cheat would still be likely to think cheating isn't as common as it really is, so they would still think they should tell the truth to get the biggest score.
Some things worth noting about this test: Pessimists will likely get marked as cheaters, even if they don't cheat, because they will think bad of their peers. Optimists will likely get marked as innocent, even if they do cheat, because they will think good of their peers. Cheaters who know this info will likely have a better chance at being marked innocent.
I like the following variant : Before the test ask people to think of a number then roll a dice. If the number they choose matches the number on the dice, they have to lie on the question. That way there is less incentive to lie, because if the truth is embarrassing, you can always say that you didn't really write the truth and that you lied because of the random number. This somewhat attenuates the "lying to yourself" problem but not completely. Then when you get the test results, you'll know that about 1/6 of them are false, which allows you to accurately compensate for that.
The thing is, people live for a long time, and if the question is "have you ever cheated", I think it's safe to say that someone who goes on higher degrees studies will have participated in thousands, if not tens of thousands of controls / homework in the course of his life, and the probability that someone has actually never, ever, ever cheated whatsoever, is in my opinion pretty slim, by the simple fact that we are humans, unperfect humans, and even though cheating is bad, cheating once in a lifetime isn't a big deal, and even people that are profoundly calm have surges of wrath sometimes. So I'm not sure overestimating the number of people cheating is always a sign of cheating in on itself. It could just be that you are cynical and unfaithful of humans.
So all this "data" is based off of people's responses, which may or may not be truthful, and it also factors in some completely wild guesses, where they are asked to pick a percentage out of thin air. On top of all that, lots of psychological bias when designing and interpreting the data, and bribing people to get a good "iscore". Even after that, all you get is a probability. Conclusion: the results are completely dubious at best, and worthless at an individual level.
I've been in classes where I know at least a third of my classmates are cheating. I never have, but if I put down 33% that obv would've been seen as me lying about cheating. I really hope this thought experiment is never actually used cuz it's very flawed lol
I think the thing about cheating is that these days school isn’t about learning it’s about the piece of paper at the end and if you end up having to relearn it anyway proving you learned it once means your capable of learning it. I’m not saying it’s a good thing, believe me, it makes me sad. But nobody wants to spend hours and hours of their week doing homework especially for classes that are required for graduation and basically meaningless otherwise.
Idk man. I never cheated on a test and yet I believed a lot of people around me did. In fact, when I was younger I believed that I was somehow ‘better’ than those around me because I didn’t cheat and it was an active motivation to keep me from cheating. I feel like there’s some further psychology to explore here. Maybe I’m just an outlier. Wait…no that’s what got me here in the first place. 😂
Lots of the people in the comments saying "I think a lot of people cheat, but that shouldn't get me labelled as a cheater." The study doesn't predict whether you are cheating based on how much you think other people chat. It uses statistics to predict the number of people that are lying, but can't tell us who they are.
Wait, homework is worth something in the us? Here in the netherlands there is a lot more freedom homework wise. But we're told not to come crying when we dont do it and get a low grade. Homework is 100% free choise for me.
@@DrTrefor hmm, interesting. Well its also true that we here in the netherlands start experimenting with homeworkless education. Which is showing some promise.
here's a different method: just ask the question and how many weeks ago they learned how to answer it, so if they're cheating then they would probably get the answer wrong
this is a bit... flawed at least like imagine a classroom of students who mostly don't mind phones going off in class and sort of tune it out, and for whatever reason a no phone rule either doesn't exist or isn't enforced Now imagine handing this test to the one student who is constantly annoyed by phones going off and as a result turns theirs off to limit the annoyance as much as they can
Isn't the incentive for everybody to guess that 99.9% of everybody else is cheating? That would give them the highest iscore. Wouldn't you want to reward the person whose iscore is closest to zero?
Damn. I thought you said "Have you ever cheated before on your homework or your cactus". I had to check and was disappointed when I found out you didn't say that. Do you want people to cheat on their cactus? What's wrong with you?
I don't think this psychological principle holds for all things. For example, the question "Do you litter" The results would be less than 5% responding Yes, but the mean estimate would be 25% or higher. And none of those people need have lied. It could very well be that 5% of people are littering, but that they create such a large amount of litter, together with accidental litter, that it appears to a lay person that 25% of people are littering. There are valid reasons one might reasonably estimate a higher percentage than average outside of lying.
Take my word for it, I've not cheated on taxes, homework, or hit the dislike button on your videos. I live in Sweden, I just have to log in to the website of the Tax agency, and click a few times and then log off, and it's done. I didn't do homework, homework is useless, and does nothing for learning. And the amount of YT videos I've pressed dislike on, is despite it being more than a decade spent on here, significantly less than 100, it is most likely greater than 2 and less than 10, but I'm not certain, it is hard to remember 10 years of activity. And I can't say that there have been a great multitude of videos I've liked either. Also probably less than 100. So in general I am an honest person, however if you hand me a deck of cards, you'll bet your arse I'll be doing my best to stack them in my favor.
This assumes noone answers "Yes, I did cheat" if the haven't. But maybe there are people who just want to skew the result in an direction in order to have a guessing advantage over the others?
Having earned three degrees I actually had to opportunity to OBSERVE actual cheating in action once, and the result of cheating another time. In the former case, it was absolutely blatant. In the latter it was pretty obvious that someone got a hand because said individual made it into an elite honors-style program and was clearly not bright enough enough to play. The head of school (who is a dear friend to this day) didn't have absolute proof of the cheating but the fact that the person failed to reveal a felony conviction made it easy to deny a licensure recommendation. Aside from that, I am at my core an honest person, and I like to think the best of others until they prove otherwise, so I would fail horribly at winning the money!
Rating popular opinions about perceptions of popular ethics is no different than rating anything else. Science and math around inter-rater and intra-rater reliabilities already has a rich and well-established research field. Look up common IRR statistics, like unweighted and weighted Kappa statistics, whether of Cohen or Fleiss forms, or the rather complicated approach of Krippendorff's Alpha, or the relatively simple converse of Gwet's AC1.
Now do the Iterated Cheating Survey and see what strategies develop! Because capital t Truth is definitely something that is revealed with monetary incentive...right? Alternate punchline Student: "But where do prior probabilities/actual frequencies come from?" Master: "That is the deep Bayesian magic, not for the faint hearted or the monetized video."
5:13 sorry for double commenting, though ive internationally made a dramatically high guess in my mind dispite never cheating, mostly cuz i think the idea of cheating is pointless and takes more than it gives But i settled on anywhere between 40% to 70% exclusively, i honestly dont care how many people cheat, im not gonna join that crowd of time wasters when im trying to ACTUALLY get knowledge to PRACTICE my career and follow my dreams, seriously, if you spend hundreds of hours and resources to not learn then just drop out, am i right?
Isn't there still potential for the sensitive question to bias people's answers to be _too high?_ If I were taking this test and (1) I recognized the sensitive nature of the question and (2) thought that people would under-report the true amount they cheat but still give high estimates to the rates of cheating, then I might want to _lie and report that I have cheated_ even if I haven't, to make up for those people.
maybe the qurstion should be framed differently is a person selling performance-enhancing drugs 'cheating in sporting events'? maybe you would say yes, i would say no to cheat, i think you have to participate and fix your own results, else you help someone else cheat 'i don't run marathons; i cheat in marathons' sounds nonsensical to me then, you will also have a good or inflated estimate of the amount who cheat, even though you are just part of the 'industry' i see it as 'do you know how many people smoke? do you smoke?' asked to a non-smoking representative of British Tobacco some people will just know the statistics
2:27 I would not do anything "for the money", I see doing things "for the money" as being corrupt. So for example, there are 2 jobs, job A pays way more than job B, however I am much much happier at job B, so I would stay at job B, I might get way less money, but at least I do something I like. So in the case of your situation, if I were a participant I would not go out of my way to get the best possible iscore just because there was a monetary incentive. I would also like to say that if I myself do a certain thing, I don't go around thinking more persons do it, I tend to prefer to do things that are done by less persons. Real life example: If there is a direct route from my current location to my destination I always try to take the most roundabout route. As for 8:46.... People have already judged me. Nobody, not even me, has to know any of the good things I've done.
5:06 I lik cricket. I find I always significantly underestimate how many people like cricket where I'm from because I know it's a sport of declining popularity. Does this type of logic invalidate the test?
If I was in it for the money, and I think the true answer was going to be higher than the people who admitted it, I would say I cheated (whether or not I actually did)
i mean for this question to come up theres gotta be some reason why students cheat right? of course you can say that its negligence, but theres a lot more factors going on besides just "not caring about studies" i guess thats off on a tangent. interesting video nonetheless
Ngl I don't think this is very accurate since I don't think your assumption that you think something is more prevalent if you do it yourself is necessarily true.

I've got nothing to back this up but I have a feeling that there is some correlation between academic integrity and propensity to lie on a survey. I doubt it's a one-to-one correlation but the situations are both tests of integrity
@@stephenchurch1784
The motivation to cheat on schoolwork is different from the motivation to cheat on a survey.
I thought the exact same thing, but I realized, the iscore for a yes answer would increase, but the frequency of ticking no and the probability guessed of people ticking no can also be used to create an iscore. This iscore would drop by doing this
Not clear but maybe your iscore is based on your answer on whether you personally cheated. I.e., if you say you did not cheat, iscore measures positive surprise of percentage who didn’t admit cheating vs percent you expected to not cheat. One thing he doesn’t address is survey size. If there is a large survey, your confession is going to have a minimal impact on the iscore.The whole Bayesian survey design might still have predictive value because of the effect he describes of believing most people are like you, but large survey size will dilute the incentive to be truthful.
if you underestimate, i thought your iscore would be lower?
This is awesome. I am an undergraduate student who participated in the study. One of the writers is my lecturer. It is very interesting to see this explanation!
So, I’ve written many papers for peers but have never myself cheated on any assignment. That raises my prediction of cheating frequency and confounds the “serum.” Perhaps it would be better if I were asked if I’d “participated” in contract cheating, to which I’d answer yes.
Or, to put it another way- I believe that many people cheat but I don’t cheat myself. So, how should I answer the questions to best earn the money? Should I lie and say that I do cheat in order to get closer to the mean values, or should I use Bayes’s theorem to update my beliefs on how likely people are to answer the first question affirmatively? It’s an interesting question if you consider the problem from the outlier of someone who’s facilitating the cheating but not cheating on their own work.
A sobering lesson in why the statistic is useful over a large sample, perhaps, but not for any specific individual.
"written many papers for peers" == cheating

This is the perfect time for this video for me. I am currently learning discrete math and I love seeing real world examples of it! Keep up the great work, Professor!
Glad you enjoyed! Good luck in discrete math:)

Did I miss something in my Discrete Math class? Cause I actually learned this in Basic Statistics. Maybe I forgot.
This topic isn't discrete math. He's saying he loves seeing examples of real world math because he's studying it.
OMG! He figured out the thing that psychologists seem to be unable to : "Sometimes people lie".
you think psychologists don't know and account for that...? That's like the first rule of the social sciences.
@@idontwantahandlethough Oh i know ways, all their conventional ways are ineffective and the only types of research that would yield somewhat useable data is unethical and would not pass ethics committee, best they can do is what they are doing using flimsily barely proven concepts and pile their barely provable hypothesis on top of those flimsily barely proven concepts.
Even Bayesian Truth Serum has gaping holes, you cant statistically account for maliciousness because malicious people are by their nature unpredictable, all you can do is construct a rigid narrative and compare everything to it but by that point you are no longer dealing with science but with religion or a cult, which is where i see psychology at, although i have to say honor to the exceptions however there are few of those.
@@lordhater4207 most sciences have their unknowables.
It's like saying physics wasn't a science before we observed light's properties as a wave and a particle or before we proved quarks and stuff or before we figured out gravity (oh wait, we didn't really yet, i guess physics must not be a science)
@@blahybris608 Yea i know psychologists like to compare themselves to physicists or mathematicians however that's like comparing apples with anvils, physics is a WELL very WELL defined science because it's research is limited to physical realm be it infinitesimally small or incomprehensibly large it's still within physical realm, physics can be wrong about their hypothesis however if a hypothesis is wrong only that hypothesis is wrong and perhaps its branch.
I like to use reverse engineering as an example, physicists can see memory of the system (nature) and corresponding values of STATIC memory addresses point (both discovered and undiscovered laws in physics) at they assume how background processes (that which they can't see or understand by observation alone) produce values they see those STATIC address point at ,and test it out, when and if they are wrong it's not the fault with STATIC address but of their assumption, they can backtrack what they did wrong since subject of their study is static and so they can simply pick themselves up and start over having learned even in failure since their fail may just be data type and not wrong assumption, however physicist cannot CHANGE variables because if that were true then we could turn gravity off, physicist is not in control of nature it's just its scribe it's documentor and observer, this isn't true when it comes to psychology psychologists may see memory of the system (human) however their problems are way more complex than the one physicists have all due to a fact that their memory addresses aren't static they are dynamic as in they change due to all sorts of reasons from subject of their study (humans themselves) to the methodology used to uncover background processes (research) that when they are wrong and they often are cannot even bactrack what went wrong because by the time they do address had changed and they don't know if it is environment, is it the subject , is it methodology in other words psychologists due to the research can and do change variables and can influence outcomes, this doesn't happen in mathematics or physics and since it's simpler when compared to psychology they can do some really impressive stuff with it some highly complex experiments and still be valid because subject they study is static, whereas what psychology would do with complex experiments is only introduce yet another point of failure, thus is the reason why they limit themselves on questionnaire "research".
@@lordhater4207 chill bro
Well, if a question such as, “What percentage of people do I think have cheated on a test?” or something like that, I usually answer somewhere over 50% because while I never cheat on any of my tests, I am aware that people do cheat. These usually come from rumors of instances of students paying people to write their essays or buys answers of test questions, etc. Prior to all this, I seriously didn’t think people who pay up to cheat because the consequences were quite severe if you were caught cheating. It scares the crap out of me and so there was no way I thought people will still cheat considering the consequences.
I can't believe that Bayes could go from Medical testing to Cheat detecting. Incredible! Thank you for providing this brilliant video!
In my school the professors say im supposed to just copy from those that know...and use that as the learning process. Apparently, homework is supposed to always be a social event. Wheras exams are not.
Really great video!
One question that might want to be added is if that person *knows* if another person cheats. If a person who doesn't cheat, but knows another person cheated, will assume that most people cheated and be marked a cheater in this test.
I remember a take-home exam in college where nearly two-thirds of the students in the class worked together on it, despite *signing their name on the first page of the test to say that they would not use outside help*. They got caught (prof said they all used some weird notation that wasn't taught in class), and each received 0 points on an exam worth a solid 20% of their final grade.
The heuristic in this video would probably mis-categorize me, because I've never cheated but I'm now convinced that pretty much everyone else regularly does.
I watched pretty much everyone I went to high school with cheat, so I guess I have a notion that its way more common than it is.
This method is going to pick up a bunch of neurodivergent people that are answering honestly, but angry about others behavior
I'd need to read the original article and the reviewers' comments, but off the top of my head, if you financially incentivise people to give surprising answers, you will get surprising answers.
Suppose I didn't cheat, but I want to maximize my iscore so as to get as much money as possible from the experiment. I could answer that I do cheat, thinking that as a rare thing that people will predict to be rare, my answering this will nudge up the iscore for it. More, I could guess that others might have the same rationale, boosting it further! This, whereas on a survey with no incentives I would likely answer truthfully that I didn't cheat. This creates a biasing of the responses.
So great, they get a result with a much higher percentage of cheaters than before - but how do they know those results are more truthful than the standard survey? Again, I'd need to read the paper, but I'd argue that they can't know that.
"More, I could guess that others might have the same rationale, boosting it further!"
Guessing that most people have this level of meta-thinking would be irrational. You can look at past studies of this kind and see how many people act GT-optimal or adjacent, and how many just do what seems prima facie correct.
It's actually ironic, because you are engaging in literally the same bias relevant to the bayesian truth serum. It's an example of "You are more likely to believe X is common, if you do it yourself." but with the variable X being equal to "thinking at multiple metalevels" rather than equal to "cheating".
@@tudornaconecinii3609 I didn't say "most" - I said "some". Assuming I would be the only one to think of it would be irrational in itself.
Either way, whether I am overestimating the portion of people who would game the system or not, so long as it is not zero this would still produce a bias - rather than produce more truthful results.
Glancing at the research, it seems they did try to control for such effects, so I'm not that far off the mark. However, I haven't yet read the whole thing.
@@Polymeron Your overestimation of the number of people gaming the system is directly relevant to your instrumental goals here, since it skews your answer to the second question, which results in you getting less money.
I'm not proposing that you assume you'd be the only one to think it. I'm proposing precisely what I proposed: namely, to look at past studies of this kind and see how many people act GT-optimal or adjacent, and how many just do what seems prima facie correct.
Because knowing to what extent people are superficial thinkers will directly boost your accuracy in answering questions of the second kind.
@@tudornaconecinii3609 It still seems irrelevant.
First, If my estimation of people's estimation for the question is very low, then just my lying alone should make the surprising result more common than expected.
Secondly, my point was specifically that people being encouraged to write surprising results, can introduce a bias - rather than only eliminate an existing bias. You can't both say that people will not act rationally and thus there will not be a biasing effect, and *at the same time* claim that the introduction of the incentive *will* have an effect because it changes people's behaviour as they try to maximize their gains.
(Note how neither point hinges on my throwaway comment that an actor thinking of lying may further consider others doing the same as further incentive to lie)
@@Polymeron "(Note how neither point hinges on my throwaway comment that an actor thinking of lying may further consider others doing the same as further incentive to lie)"
I am aware of that. I am not saying "I think you're wrong on this particular point, which breaks down your overall argument". I am saying "I think you're wrong on this particular point, full stop."
I agree with your overall argument. I just didn't think of mentioning that.
Truth be told I rarely thought that individuals cheated until I talked to a professor and over heard a conversation of students who did cheat. I am appalled that some students do cheat on stuff
I am kind of a pessimist and I think a lot of people cheat despite not being a cheater.
Oh boi, do a whole 10% of people ACTUALLY pay others to do their homework for them? I'd have guessed 1 or 2 percent... people with more money than brains.

@@РоманБурый-х4б hahaha
@@РоманБурый-х4б or just beat up a nerd🤓👆
damn. I would have guessed around 20%... but I dont cheat
What if a genuine person thinks many other people would cheat on the same difficult exam? Isn't this survey biased to only assume that genuine/not genuine people would think other being genuine/not genuine?
I was thinking the same thing, if someone actually didn't cheat, nothing stops them fir thinking other people cheated
or maybe they dont cheat but they know some people that cheat which will still psychologically bias them towards thinking more people do it

You have a great knowledge. Love from india 🇮🇳
8:51 was my philosophy essay today
Lol, I got an ad for Chegg right after this
um lol that is ridiculous!
My guess was based on two factors who would cheat if given the chance 40% the amount that actually would go for it would greatly depend on perceived difficulty and consequences about 20%
2:01 as someone whos taken statistics courses...
That second question is flawed. You have to always put in a neutral or "i dont know" type of option, or else your survey is unreliable.
In exams there were always those who went to the toilet a few times. Seriously, I don’t believe they needed to go,and were looking at information in private. Although I’ve never cheated my observations would make my estimation of cheaters quite high.
I paid someone to watch this video for me so that I could say that I saw it myself.
I'm not sure I buy it. This is based on a cognitive bias. Does everyone have that cognitive bias? If so, is it to the same degree? (I don't have answers to either question but I suspect the answers are: Yes, and almost certainly not). If we can't assume that everyone has the bias or that it isn't to the same degree the numbers become a minefield of best guesses. Perhaps they are accurate, but perhaps they are not.
In any case, very interesting video.
Also, the bias depends on the environment. For example, even though I didn't cheat, many of my schoolmates did, or at least were planning to. So, my bias would be in an opposite direction.
@@Yorick257 exactly as you say. From viewing my peers throughout HS I would have said 50% cheat. The question would also have to be more specific, what defines cheating in my mind is probably different than other people.
Did you finish the video? He tackles this at the end, at 9:38.
While it's impossible to identify individual cheaters, the methods here are still useful to make predictions about a population. Variation can and will exist, but in statistics you usually fight variation with large sample sizes and some math.
@@Palozon Yes, there will be variation. How much? You need to know that in order to deal with how it affects the numbers. Even taking a sample size of a billion would be useless unless you knew what the variation was.
@@SlimThrull I didn’t watch the video, frankly because I’m more interested in the psychological side than the mathematics of cheating, so I don’t know what method he is using. However, if he is using inferential statistics, then we can use various methods (which you would know about if you’ve taken statistics classes) to find the variation.
This is awesome, thanks for making this video and I’m glad you found my team’s study interesting. Best regards Guy Curtis
Your team did the study? I have a question for you if you have a moment. Did your team assume that the cognitive bias was the same for everyone? Since different biases affect people in different ways, it make sense (to me anyway) that a single bias might be more or less likely in a person rather than the next person. If that's the case, how did you adjust for that in the study?
I didn't expect that the correct spelling is not "theorem" but "serum"...
Trefor is such a goober. Old UC student here. Love you
I don’t get it
"Have you ever clicked dislike" "How would i know you are telling the truth?" No way dude, blame YT for that
You can also add more questions like this but where the answer is more obvious to get a sense of if this person is a higher chance of lying in general than others.
Watching this so I know how to avoid the Bayesian Truth Serum
Me who's gonna break the system by putting no i didn't cheat and 100% them cheated
I just found your channel one week ago... I've been binge watching every single video you uploaded, you have a great energy when explaining things, I love it! Could you share the doi/title of the paper you were analyzing?
There are also the people who _know_ a ton of people cheat but don't personally do it.
What if ~90% of the class cheated, and the 10% who didn't cheat get a bad score on the survey? How would you identify the group that cheated (good survey scorers) from the bad scorers, or is it an assumption that the majority is the one that doesn't cheat
Great video, fascinates me actually. Subscribed right away!
Thanks for the sub! In that scenario, those who didn't cheat would still be likely to think cheating isn't as common as it really is, so they would still think they should tell the truth to get the biggest score.
Actual adults are also capable of witnessing other people acting poorly without having a desire to imitate them.
Some things worth noting about this test:
Pessimists will likely get marked as cheaters, even if they don't cheat, because they will think bad of their peers.
Optimists will likely get marked as innocent, even if they do cheat, because they will think good of their peers.
Cheaters who know this info will likely have a better chance at being marked innocent.
"I can attest that a lot of students don't do their Homeworks"
~A Paid Homework Maker
I like the following variant :
Before the test ask people to think of a number then roll a dice. If the number they choose matches the number on the dice, they have to lie on the question. That way there is less incentive to lie, because if the truth is embarrassing, you can always say that you didn't really write the truth and that you lied because of the random number. This somewhat attenuates the "lying to yourself" problem but not completely. Then when you get the test results, you'll know that about 1/6 of them are false, which allows you to accurately compensate for that.
Interesting!!
Projection, I only know what is in me. Whatever I see in the world must reflect what I am, not in others. I must do a lot of projection then...
The thing is, people live for a long time, and if the question is "have you ever cheated", I think it's safe to say that someone who goes on higher degrees studies will have participated in thousands, if not tens of thousands of controls / homework in the course of his life, and the probability that someone has actually never, ever, ever cheated whatsoever, is in my opinion pretty slim, by the simple fact that we are humans, unperfect humans, and even though cheating is bad, cheating once in a lifetime isn't a big deal, and even people that are profoundly calm have surges of wrath sometimes. So I'm not sure overestimating the number of people cheating is always a sign of cheating in on itself. It could just be that you are cynical and unfaithful of humans.
Humans are surprisingly consistent
So all this "data" is based off of people's responses, which may or may not be truthful, and it also factors in some completely wild guesses, where they are asked to pick a percentage out of thin air. On top of all that, lots of psychological bias when designing and interpreting the data, and bribing people to get a good "iscore". Even after that, all you get is a probability.
Conclusion: the results are completely dubious at best, and worthless at an individual level.
Got it. So if anyone asks me how many people I think cheat on their calculus just say "no one".
This isn't proof someone cheated.
I think I'd be an outlier on such surveys
Do it the scientific way. Have them show you their work on the white board after the class.
I've been in classes where I know at least a third of my classmates are cheating. I never have, but if I put down 33% that obv would've been seen as me lying about cheating. I really hope this thought experiment is never actually used cuz it's very flawed lol
I think the thing about cheating is that these days school isn’t about learning it’s about the piece of paper at the end and if you end up having to relearn it anyway proving you learned it once means your capable of learning it. I’m not saying it’s a good thing, believe me, it makes me sad. But nobody wants to spend hours and hours of their week doing homework especially for classes that are required for graduation and basically meaningless otherwise.
Idk man. I never cheated on a test and yet I believed a lot of people around me did. In fact, when I was younger I believed that I was somehow ‘better’ than those around me because I didn’t cheat and it was an active motivation to keep me from cheating. I feel like there’s some further psychology to explore here. Maybe I’m just an outlier. Wait…no that’s what got me here in the first place. 😂
Big retweet over here
Lots of the people in the comments saying "I think a lot of people cheat, but that shouldn't get me labelled as a cheater." The study doesn't predict whether you are cheating based on how much you think other people chat. It uses statistics to predict the number of people that are lying, but can't tell us who they are.
Thanks, now I’ll know to answer 0% if I get a frequency question.
Comparing cheating on the homework and cheating on your partner is like comparing killing a flea and murdering a person
Wait, homework is worth something in the us?
Here in the netherlands there is a lot more freedom homework wise. But we're told not to come crying when we dont do it and get a low grade. Homework is 100% free choise for me.
I’ve generally found students are must less likely to do homework that isn’t for marks, but will do it if there is the incentive there
@@DrTrefor hmm, interesting.
Well its also true that we here in the netherlands start experimenting with homeworkless education. Which is showing some promise.
If it's a geometric mean, how do you take 0s into consideration?
here's a different method: just ask the question and how many weeks ago they learned how to answer it, so if they're cheating then they would probably get the answer wrong
or you may get the answer wrong because you remembered the information and not the exact date you learned the information lol
Your channel is amazing
Guess this assumes that people think that they're "normal" - which is another factor. I, for example, would rate my interests as uncommon.
Ain't never heard of no Beijing tooth syrup before so thank you 🎂
This wouldn't work if a cheater suspects a Baysien scheme at play.
this is a bit... flawed at least
like imagine a classroom of students who mostly don't mind phones going off in class and sort of tune it out, and for whatever reason a no phone rule either doesn't exist or isn't enforced
Now imagine handing this test to the one student who is constantly annoyed by phones going off and as a result turns theirs off to limit the annoyance as much as they can
this isnt what i wanted when i searched BTS...
Isn't the incentive for everybody to guess that 99.9% of everybody else is cheating? That would give them the highest iscore. Wouldn't you want to reward the person whose iscore is closest to zero?
So... did the study have any cross-checks for *over*estimating the prevalence of cheating?
Damn. I thought you said "Have you ever cheated before on your homework or your cactus". I had to check and was disappointed when I found out you didn't say that. Do you want people to cheat on their cactus? What's wrong with you?
Well now I now how to treat bayesian truth serum
Good job.
I do not understand, why do not lied that we do not cheat and select that nobady cheat. So I minimaze probability a lot and still can get iscore?
exactly
Teacher:*have you cheated?*
Me who cheated my way through all the boring classes:
Edit: only cheated with cheatsheets tho
9:51 Yep, I cheated with some frequency in school and would have guessed around 5% or lower lol
I don't think this psychological principle holds for all things.
For example, the question "Do you litter"
The results would be less than 5% responding Yes, but the mean estimate would be 25% or higher.
And none of those people need have lied. It could very well be that 5% of people are littering, but that they create such a large amount of litter, together with accidental litter, that it appears to a lay person that 25% of people are littering.
There are valid reasons one might reasonably estimate a higher percentage than average outside of lying.
Take my word for it, I've not cheated on taxes, homework, or hit the dislike button on your videos. I live in Sweden, I just have to log in to the website of the Tax agency, and click a few times and then log off, and it's done. I didn't do homework, homework is useless, and does nothing for learning. And the amount of YT videos I've pressed dislike on, is despite it being more than a decade spent on here, significantly less than 100, it is most likely greater than 2 and less than 10, but I'm not certain, it is hard to remember 10 years of activity. And I can't say that there have been a great multitude of videos I've liked either. Also probably less than 100.
So in general I am an honest person, however if you hand me a deck of cards, you'll bet your arse I'll be doing my best to stack them in my favor.
Great video! Thanks!
Glad you liked it!
This assumes noone answers "Yes, I did cheat" if the haven't. But maybe there are people who just want to skew the result in an direction in order to have a guessing advantage over the others?
Having earned three degrees I actually had to opportunity to OBSERVE actual cheating in action once, and the result of cheating another time. In the former case, it was absolutely blatant. In the latter it was pretty obvious that someone got a hand because said individual made it into an elite honors-style program and was clearly not bright enough enough to play. The head of school (who is a dear friend to this day) didn't have absolute proof of the cheating but the fact that the person failed to reveal a felony conviction made it easy to deny a licensure recommendation. Aside from that, I am at my core an honest person, and I like to think the best of others until they prove otherwise, so I would fail horribly at winning the money!
I ve already lied
But i don t remember having ever cheated in my life
Rating popular opinions about perceptions of popular ethics is no different than rating anything else. Science and math around inter-rater and intra-rater reliabilities already has a rich and well-established research field. Look up common IRR statistics, like unweighted and weighted Kappa statistics, whether of Cohen or Fleiss forms, or the rather complicated approach of Krippendorff's Alpha, or the relatively simple converse of Gwet's AC1.
Now do the Iterated Cheating Survey and see what strategies develop! Because capital t Truth is definitely something that is revealed with monetary incentive...right?
Alternate punchline
Student: "But where do prior probabilities/actual frequencies come from?"

5:13 sorry for double commenting, though ive internationally made a dramatically high guess in my mind dispite never cheating, mostly cuz i think the idea of cheating is pointless and takes more than it gives
But i settled on anywhere between 40% to 70% exclusively, i honestly dont care how many people cheat, im not gonna join that crowd of time wasters when im trying to ACTUALLY get knowledge to PRACTICE my career and follow my dreams, seriously, if you spend hundreds of hours and resources to not learn then just drop out, am i right?
Did you cheat?
No. Cheat did me.
The average student paying for people to do a Google search
Isn't there still potential for the sensitive question to bias people's answers to be _too high?_ If I were taking this test and (1) I recognized the sensitive nature of the question and (2) thought that people would under-report the true amount they cheat but still give high estimates to the rates of cheating, then I might want to _lie and report that I have cheated_ even if I haven't, to make up for those people.
The people who would know the most about how what proportion pay for cheating would the people who are selling answers.
That's also cheating though.
maybe the qurstion should be framed differently
is a person selling performance-enhancing drugs 'cheating in sporting events'? maybe you would say yes, i would say no
to cheat, i think you have to participate and fix your own results, else you help someone else cheat
'i don't run marathons; i cheat in marathons' sounds nonsensical to me
then, you will also have a good or inflated estimate of the amount who cheat, even though you are just part of the 'industry'
i see it as 'do you know how many people smoke? do you smoke?' asked to a non-smoking representative of British Tobacco
some people will just know the statistics
2:27 I would not do anything "for the money", I see doing things "for the money" as being corrupt. So for example, there are 2 jobs, job A pays way more than job B, however I am much much happier at job B, so I would stay at job B, I might get way less money, but at least I do something I like. So in the case of your situation, if I were a participant I would not go out of my way to get the best possible iscore just because there was a monetary incentive. I would also like to say that if I myself do a certain thing, I don't go around thinking more persons do it, I tend to prefer to do things that are done by less persons. Real life example: If there is a direct route from my current location to my destination I always try to take the most roundabout route.
As for 8:46.... People have already judged me. Nobody, not even me, has to know any of the good things I've done.
5:06 I lik cricket. I find I always significantly underestimate how many people like cricket where I'm from because I know it's a sport of declining popularity.
Does this type of logic invalidate the test?
If I was in it for the money, and I think the true answer was going to be higher than the people who admitted it, I would say I cheated (whether or not I actually did)
What if someone answers zero?
i mean for this question to come up theres gotta be some reason why students cheat right? of course you can say that its negligence, but theres a lot more factors going on besides just "not caring about studies"
i guess thats off on a tangent. interesting video nonetheless
Ngl I don't think this is very accurate since I don't think your assumption that you think something is more prevalent if you do it yourself is necessarily true.
Aren't you then asking "how many people answered yes/no"?
The only thing the Oz study showed is that the participants are somewhat naive.
Have you cheated? Yes
What do you think the cheating prevalence is? 0%
Wait, how? I lied on this survey.
