I’m not commenting on how many takes that took. But feel free to guess! (And if you must know: the complete footage of every attempt will be uploaded to Patreon. patreon.com/standupmaths )
The missing bracket just means that the rest of the paper, and indeed the rest of all existence after you started reading the formula, is now part of the formula.
Fun fact; one of the guys who noticed this statical unlikeliness and called dream out got caught cheating by also futsing with the games probability. I guess cheaters recognize cheaters
Odds of Winning the Lottery: 1 in 302.5 Million Odds of Getting killed by a Shark: 1 in 264.1 Million Odds of Being struck by Lightning: 1 in 500,000 Multiplied Together: 1 in 2.5 * 10^23, which is just 1 order of Magnitude less likely than Dream's luck.
@@jasonlewis4438 Winning the lottery is definitely not "just" 1 in 302.5 Million, so you could easily pick a lottery with a more favorable chance of winning, making the original statement true. By doing that you would have made the joke better, instead of trying to ruin it :-(
My probability class did an exercise... they had one student flip a coin 100 times, and another student was told to just write down H&T randomly, without any props. Professor claimed that he could tell which was the true random series from the coin, because the student doing it by hand would be too shy to put in appropriate-length strings of heads (or tails) in a row. It was a neat game!
@@baritonesax245 It's been a while, but as I remember, you expect a string of log base 2(# flips) of heads or tails in a row somewhere in the sequence. The fake random sequences never had more than 2 or 3 HHH or TTT, even for 100 flips.
Numberphile did a video on this called randomness is random. Where the host does 20 flips in his head and writes the down and the other person tries to predict what he picked.
'I'm not saying he's cheating. I'm just saying if the _entire population of Earth played an entire game of minecraft every second for a hundred years,_ he's still many orders of magnitude luckier than any of them would probably have gotten.'
actually, you're *still kind of understating it* . If the entire population of Earth played *33* games of minecraft every second for a hundred years...
@Aquaintence Buddy Yeah. That's mostly just a rounding up to make a better upper limit + making the math nicer, but the speedrun vs series of six streams is an actual difference.
Okay, I played minecraft in like 2009-2010 and I did not understand how someone could possibly speed run that game.......turns out it has changed a lot in 10 years
Woah that's awesome @Real Engineering, not many people played that far back. Actually, many versions from those years are missing! There's an entire community seeking lost versions of Minecraft mostly from 2009-2010 so if you could find one in you folders that'd be incredible!
This reminds me of a quote I saw online from a journalism class. “If one source says it’s sunny outside and another says it’s pouring. Your job is not to cite both sources, it’s to look out the f*cking window and find out which is right.”
@@penguins4284 It's an old joke. Not a bad joke as it will always be useful to get a point across but still a joke not a quote (unless someone can put a name to who said it)
Dream is not a Minecraft developer so cant manipulate RNG. He could not change the RNG even if he wanted to. You just don't know the story and how Minecraft works.
I thought they were two different videos rotascoped together. Because you never see his complete arm. Both are hiding below the frame and then bam, a trick shot.
I can't tell if the book-toss was: 1) Good enough to count, no more takes, just move on. 2) Better than intended, since it didn't slot into the others but it's upright and fully visible. 3) Exactly as intended.
And this friends is why you trust mathematicians who will put their name on their papers, rather than random, unnamed, and unknown astrophysicists. Cause only one of them will willingly admit/defend when they bodge a paper.
this was a reason i gave to his rabid fans when i told them how research and finding reliable sources to work with is the best chance of dream being right however it turned out dream literally just hired someone to do incredibly bad math and came from a wix website made a couple weeks prior to this event that still had its watermark of wix on it
Wrong. Never trust authority. Trust the rules of mathematics and read what they write, not who they are. Putting blind trust in people just because some university said they can put letters after their name is just stupid. And a cause of a lot of the issues we see in the world. In the dream case , the mathematics is simple. You can work it out yourself with a calculator.
It's not enough for the scientist to put his name, considering all the potential conflict of interests in the real world, when it is not about Minecraft, but medical statistic justifying lockdowns or the lethality of a virus. In fact, I would say that only independend scientists are real scientists, everyone else is a scientific prostitute creating the numbers which are wanted by his clients. (the people who order the study to prove their ideology correctly)
Funnily enough, the scientist did redact the initial paper saying that there were alot of mistakes, mainly due to not understanding the game. Which makes sense. And btw he didn't want to put his name on the paper cause he didn't want to get public backlash from it, and lets face even if dream was innocent and the paper just proved it, he still would get alot of backlash. And in a time where having a job is so important and finding work is incredibly difficult think it's fair to want to stay anonymous to stop people calling for you to get fired, which does happen.
@@diekritischestimme That is certainly the case with "computer modelling", especially when modelling large-scale problems (like how a virus spreads worldwide). The problem is so complex, that you need to make lots of assumptions in order to make the problem calculable. And the trouble with assumptions is, people have a tendency to pick numbers that give the answers they want to see. Which is why computer modelling of these types of problems are infamous for being inaccurate, or just plain wrong. However, that doesn't stop the doom-mongers from telling everyone they are going to die of covid or the planet is going to explode in five years.
I dont think he went out and "understood" minecraft in the sense you're suggesting. It's a childs game with a simple premise, not too difficult of a concept to grasp. Not only that he seemed to have only examined the loot tables thoroughly, as that was what was in question. Understanding minecraft, as you seem to mean, isn't as easy as knowing it involves gathering resources and killing a dragon
@@sakikogookheng I getcha... but Minecraft wasn't intended to be a kids game. It's a game for everyone. Not even Notch expected so many kids to be constantly playing the game.
Eh... I don’t play it but “get pearls, kill dragon” isn’t exactly the hardest thing to grasp. A quick look at the loot tables and you are set. Come on.
@@sakikogookheng You clearly have never gotten into redstone, automatic farms, nor sorting machines. Minecraft, on the surface, is simple... Factorio, is simple on its’ surface- you crash landed on a foreign planet, build factories, build a rocket, then you win. But when you actually get into, it’s incredibly complex and requires math.
DAMN. That really put that in perspective. For reference, the diameter of our solar system from one side of the oort cloud to the other is about 1.5 light years. Basically, you could select a millimeter at any point on a line drawn between the surface of the earth and another point hundreds, if not thousands of star systems away, leave a marker on it, and the odds of randomly picking that point out of any other point would be dream's luck.
I love the unspoken fact throughout the video that so many shots were filmed in order to get those perfect odds-defying results, like the book throw, the consecutive ball hoops, the dice pairs falling in the results in the right order. Subtle, yet entertainingly on point.
It's a beautiful illustration of the question. Because I note that no one sees this and thinks matt legitimately did all that in one go. But it's way more believable that matt did that than Dream's result.
Given my watch history of countless Minecraft videos, and every video on both yours and Numberphile's channels, I'm sure the RUclips algorithm positively pissed itself with excitement when recommending this video to me.
To put that kind of "luck" in perspective, flip a penny 13 times, and if it lands on heads on all 13 times, go buy 3 lottery tickets with 1/1000000 chances of winning, if you win all 3 lottery tickets, that's the kind of luck dream would have had to have to pull that off legitimately.
@@binomial3837 No. 1 in 7.5 trillion was actually the upper bound on the chance that ANYONE would ever get Dream's luck on any set of runs. For just a random session of 6 livestreams, to get Dream's luck, it's closer to 1 in 10^22.
The "10 Billion Human Second Century" is one of the funniest things I've ever heard in mathematics. Also genius in how easy it is to convey to the public at large.
To be fair, as far as video games go, "get gear, go to hell, get item, make item, go to weird hell, kill dragon" is pretty straight forward. But i do get what you mean.

@@Ladylubber It already happened. Look at any comment section on videos that Dream fans watch and you'll see them ALL excusing his actions because he's funny. Or trying to say that things were biased to make him look bad and that it was an honest mistake, even though it's logically impossible for him to pay for a mod that boosts his luck and then forget about it when being accused of having impossible high luck.

@@mhelvens Dream also has accused another speed runner of cheating. He was proven wrong but to this day has refused to retract his accusation or admit he was wrong.
@@crypt5129 I really don’t think that video is as definitive as it presented itself to be. Don’t get me wrong, love karl and his work, but this topic is still heavily up for debate. It shed a lot of light on stuff not talked about often, but a lot of the evidence was FROM the guy being accused, hearsay, and inferences. Which is valid pieces of evidence, but there’s still room for plausible doubt I think my biggest problem though is the defense of his reaction to the problem near the end. There is no excuse for how much of a manchild dream was, and the amount of neglect he had for the moderators well being and his fan base’s rabid attacks. He has way too much influence than he knows what to do with and he can’t responsibly handle it
Thank you Dream for cheating and letting me find this incredible channel which also made Numberphile and Sixty Symbols pop up on my recommended, and now I can't stop watching and learning.
I found Matt through numberphile a couple years ago and love them both! Would also recommend Steve Mold for more general science vids in a similar style to Matt's. PS Careful about numberphile's video on why 1+2+3...=-1/12, that video has caused more controversy in the math world than Dream could ever hope to.
just for perspective, for the 10 billion human second century thing, it would have to take roughly 650.22 centuries for just a SINGLE occurrence of what happened to dream.
@@actually_tes1 it's actually just almost straight arithmetic at that point. The probability of getting Dream's result is about 1:2*10^22. The 10BHSC is about 3*10^19 By multiplying these two numbers (raw probability and number of attempts) you get a new expected value, which is something along the lines of 1:650 (1:666 with the numbers I just provided) So you're going to need 650 of those centuries to expect it to happen once. Or alternately for attempts to be even faster. Or the population to be higher.
Well and if we factor in that it takes more than 1 second to do all the accounted livestreams it would take a couple trillion years for a single occurence. Considering the age of universe we still have a couple of trillion years to go.
I actually think it's really neat that a community-run speedrunning website published a competent (at worst 'Undergrad lab paper') mathematical paper on this.
The care that they took with this shows how seriously they take the job, even though it's unpaid (right? I know nothing about the speedrunning community). Well done to them, and may their future endeavors flourish under that work ethic.
@@hammurabii.3173 Sure, I can see the speedrunners making a living off of popular games (like Minecraft!), but the mods that oversee the leaderboards don't get a share of that pot, right?
Speed runners are something else and I admire it. They often delve DEEP into the technical aspects of the game, in order to break certain parts of it. When I say break, I of course mean break the vanilla game so everyone is on the same and fair starting point mind you, not mods. Point is, they're often very skilled and nerdy homies. I also thought the paper was neat
@@benjaminoechsli1941 Mods don't typically get paid, but are almost always made up of people who stream themselves. For 99% of games, modding is a side hobby for streamers in the community to help continue to build the speedrunning scene.
I've noticed this happening more and more. I think the Internet and public schools get a bad rap for making us dumber by misinforming them, and there's probably some truth to this, but I think when used for good we're seeing more and more "citizen science" by people who would have just been farmhands 150 years ago.
@@TRW4.0 Dream has literally said that they take multiple tries to get the most exciting manhunt, it's not scripted. It's literally left up to probability of about how many tries it takes to get a good take lmao.
I just find it very human xD I find it more disgusting that people need this video to even get close to making sense of the truth while it IS very clear. As we see the math show. I would LOVE for this video to be completely unnecessary proof-wise (nothing against Matt of course), but unfortunately it is not. Cheers.
To be fair, even though in this specific context the missing parenthesis doesn't matter, a misplaced parenthesis could result in completely different equations.
@@tiredboard I would assume a professional doing analysis for a paying customer would be more focused on details like that when dealing with math. That's ignoring someone not willing to putting their name on their work.
You saying that a world-renowned mathematician would seriously not remember to close a parenthesis? I mean if you dedicated your life to math you would pretty much not make this kind of mistake. Face it; Dream himself wrote it to look better or the "mathematician" does not know what he is talking about.
this video is older now but having the book land when you flip it behind you at 17:15 is SUCH a great touch when you just finished debunking the incredibly low possibilities of this being an honest speedrun lmaooo
Fun fact: assuming there are 7.5e^18 grains of sand in the world (google), it is more likely that two people would randomly pick the exact same grain of sand out of every one on earth than what Dream did.
Idk if the above commenter is saying truth but its more like this Imagine two aliens on space looking at earth The first alien closes his eyes And the second alien lands in a random spot in earth in his spaceship and marks it The second alien comes back and blinds himself and the first alien picks the same grain of from the entire earth and mark it
Except there wouldn't be material for a video, and half a million views, if he went with "Dream just got lucky" theory. No internet figure feeding of this drama is truly disenterested.
@@Rpahut1 Are we at the "constructing conspiracy theories for why people who know what they're talking about would lie to make dream look bad" stage of bargaining at this point?
@bobin the boggart The issue is that the Speedrun mods offered to hire a statistician to review their paper, but Dream said no specifically *because* the statistician would be biased in favor of their client. After the mods offered to choose a statistician that Dream agreed on, Dream declined. And then hired his own anonymous statistician. From a website that was created just months prior. With no page listing their employees, or even verifying their existence. So it’s not simply that Dream hired his own statistician. The point is that he hired them *after* stating they would be biased.
@@zh9664 He's supposing Dream found his unnamed mathematician by searching for an expert in "astronomical odds," expecting to get someone who specialized in odds that are astronomical in the sense of being very high, but instead getting a guy who's into odds related to astronomy...because.
@@tuxedosteve9556 Mistakes aren't acceptable, and aren't the same as margin of error. Margin of error covers how much your number could differ from reality due to everything from cosmic interference to human error. A mistake is an incorrect calculation, and has no place in a paper.
No no as a S-U M stan, I can 100% with certainty confirm that was his first try attempt, he is simply that lucky. Ur a negative h8r looking for clout. It's possible among millions of ppl to throw a dart at a board that one will get it on their first try. Have u not seen endgame? Its possible. (Wow that felt terrible, this is just a joke)
It's interesting that he probably only increased his odds by a little bit, thinking it wouldn't be noticed, but forgetting that when you do things a lot of times, even a small increase in chances has a large statistical impact
The funny thing is, the situation in which it *wouldn't* have a large statistical impact is ... the situation in which it wouldn't have any noticeable impact at all. Which, if Dream intentionally modified the game, would make that act of cheating kind of a waste of time - why bother if you can't even tell the difference?
I strongly recommend Karl Jobst's video on Dream's semi-confession. It's fascinating. There's a plausible theory that he had modified his Minecraft for practise and didn't know he was *still* using a modified version when he streamed. It raises an eyebrow but honestly he makes a compelling (and very nuanced) argument on the possible interpretations of what is now known.
A slight increase in odds wont go noticed in a single run, the problem he had here was he kept using the mods run after run. In an unmodded game you're going to end up with extremely good luck and extremely bad luck in games. He effectively removed the bad luck games getting to his perfect game much faster and with less effort.
As a person who has played Minecraft from basically the very beginning, and also a regular viewer who has a deep amateur interest in math(s), this video is twice as good for me as usual.
Ah, the very beginning, the days when if you wanted to mine for resources you wanted to be darned sure to do it on one side of the (0,0) point, because the map generation was bugged and put fewer resources on the other side...
So using Math, he basically "confirmed" everyones suspicion...the odds of Dream getting pearls and rods that fast are not 0, but boy it's the closest thing to 0
If every person on the planet lived for a thousand centuries, (that's like pre-development of homo sapiens, to 500,000 ad?) And all those billions of vampires did, in a constant purgatory, was speed running Minecraft over and over. we would expect that one of them would have the experience that dream did... Probably. Lol.
I think this is a lot like intelligent life. It is incredibly rare (by what we know) so it would be extremely unlikely for us to be here. But since we ARE here that kind of messes everything up. If the odds are 1/100000000 then that would mean that us being here could look like “cheating” but since we are here no math could dispute the fact.

I can't believe whilst procrastinating on tomorrow's advanced math exam I accidentally come across a video that helped me actually learn binomial distribution and probability calculations 😅 a topic which I skipped cause I didn't attend the classes where it was taught LOL Thanks. Will definitely come back for more videos maybe i'll learn some stuff whilst procrastinating 😅😂
Dude holy crap. Like, I look at “getting 42/262 when 12/262 is the drop rate” and think “eh that’s lucky but doesn’t seem insane” until you actually do the math on it. That’s bonkers.
Yeah. The intuition that's important to have is that doubling the amount of trials obviously doubles the mean, but it doesn't double the standard deviation (how much we expect something to vary) It only multiplies that by the *square root* of two. So when if you have *four* times the amount of trials, you only get twice the deviation, even though the mean is four times as big. So suddenly this relatively small deviation (in absolute terms) becomes a completely unsurmountable mountain.
Funny thing is, that same intuition is why we know about the cheating: the hacker knew they couldn't make things TOO lucky, but they used their intuition instead of crunching the numbers and they inadvertently made a change drastic enough to expose them. What this makes me wonder about is how many other, smarter cheaters may be out there, manipulating game probabilities just by a standard deviation here and there, gaining an edge while maintaining plausible deniability.
@@polendri4812 Well, you do have to keep in mind that for every game they play they need to make sure the standard deviation is going to even out. If Dream had used the hack for a small amount of runs, it easily could've been chalked down to luck.
Just a note on the odds on those craps runs because your math ends up off because of it. The 154 roll streak was without crapping out (losing) *not* without rolling a 7. There could (almost certainly were) 7's in that run. It could have even been literally all 7's. The number for the losing roll varies depending on the phase of the game you're in. One "game" of craps consists of one or two phases. You start with a "coming out" roll. If you roll a 7 or 11 you win immediately. If you roll a 2, 3, or 12, you lose immediately. If you roll 4, 5, 6, 8, 9, or 10 that becomes your "point" and you enter the second phase. In the second phase, you win if you roll your point number before rolling a 7 and lose if you roll a 7.
Thanks for clearing that up. I remember trying to learn how to play craps once and couldnt get my head around it, but it definitely was more complex than how it was described in the video
Wait, so they were counted as 154 rolls, which would be less than 154 rounds, right? And it sounds like every roll has a smaller chance of making you lose immediately than just "not rolling 7", so the real chances would be slightly higher than what Matt calculated.
Correction: a shooter's hand in craps doesn't end until the shooter sevens out. If they crap out, pass bets lose and don't pass bets win (except that don't pass pushes on a 12), but the hand continues. The actual probability of rolling at least 154 times in a single hand works out to be about 1.788 824 26 × 10⁻¹⁰, or 1 in 5 590 264 100. If crapping out ended the hand immediately, the odds would be closer to those calculated in the video, since every roll would have either a 1/6 or 5/36 chance of ending the hand. Instead, it's either 1/6 or 0. *Reference* Ethier, S. N. & Hoppe, F. (2010). A world record in Atlantic City and the length of the shooter’s hand at craps.

I know I am a bit late. But I love how, Matt gave Dream, the highest benefit of the doubt, by giving him 10 billion instead of the *calculated* 7.9 billion population (in 2021) and still Dream was orders of magnituted luckier than all of them.
More than a benefit of the doubt, these numbers are ridiculously in Dream's favor. If 10 billion people each killed 305 blazes and made 262 barters every second of every day for 100 years, there is still only a 1/1000 chance that even a single person would have matched or beaten Dream's luck. Dream is but a single person playing over maybe a couple of dozen hours at most.
The population of the world is estimated. Maybe the estimate uses a calculation. But it's a bit misleading to say we calculated the actual population of the world and somehow got exactly 7,900,000,000
@@B3Band 7.9 billion and exactly 7,900,000,000 are completely different levels of precision. 7,900,000,000 plus or minus almost 50,000,000 is still 7.9 billion, but it is not 7,900,000,000.
My Data class in University recommended this video for us to watch as to how to detect cheating. This entire story is hilarious, especially since he fought back against actual professors and used misleading data. He's such a textbook example of cheating, lmfao.
You should watch Karl Jobst's recent investigation into the digital papertrail of communication between Dream, the mods, the person he reached out to to make an analysis, the company that made the mod for his casual streams... There is a strong case that given the circumstances, he actually may be genuinely telling the truth about his fundamental defense of not knowingly using a mod that altered the drop rates. The guy's behavior isn't "textbook." The amount of hours and money he poured into fighting the allegations, eventually caving in to try and stop the bleeding of his already tarnished irreparable reputation. The facts of the story lining up to the surface level depiction of the situation is mathematically impossible in and of itself. It's really a fascinating piece of journalism by Karl.

@Princex69 Disclaimer: Not a MC player, I've just watched a few videos. Dream submitted a speedrun, speedrun was considered pretty lucky due to the drops needed to finish a run (Blaze Rods & Ender Pearls). People then started wandering if there was any foul play, countless MC players calculate the odds, astronomically high luck was needed for the speedrun. Dream hires a "mathematician" to disprove the accusations, he was asked to show his MC folders to show that he had no add-ons or mods installed, he was not able to show them due to some circumstances. Time passes and he "admits" that the run he submitted actually had mods installed to increase drop chances (Blaze Rods and Ender Pearls) but he did not know they were active. Plausible alibi, since he has said that he uses those for his other videos (Manhunt?). His run was then removed from the leaderboard. Apologies for any mistakes.
@@moodymud it doesn't really matter if its just been invented, in the same way if I use a light Eon as a unit of measurement, it may not be recognized as a unit of measurement but you are able of extracting actual information from that unit, its the same with the 10 Billion human second century, it's just a way of putting something into perspective
The huge sample biase is never resolved though. I could go to the family of the smartest person alive (similar ridiculous likelihood) and then say I chose 1 person out of 5 that were there at the family meeting. If I consider all 5 its not less ridiculous, so this person cannot exist, even if he is in front of you. similar youd have to pick all the minecraft runs there ever were.
The analogy of hitting a target with a randomly thrown dart vs drawing a target around a dart that has already been thrown is a very useful one for discussing probabilities, I will definitely be using it myself.
my favorite thing about the dream controversy is seeing a bunch of non-minecraft youtubers with non-minecraft audiences explain just enough about minecraft to somewhat understand the speedrun
Same! I wanna see him take on bastion strats now. Gimme an analysis of the new manhunt route for housing and why it's better than the dip route on bridge pls.
As someone brought here through the speedrunning side of things, I've gotta say that I can always appreciate anyone who knows the difference between "disinterested" and "uninterested".
@@Mr_Doogz "Disinterested" means impartial, free of bias. It's derived from "interest" in the sense of having a financial stake in something. So if you're disinterested in some dispute, it means you have no stake in the outcome, no ties to either party. You're a neutral observer.
The fact that a physicist did the math for Dream should tell you everything you need to know. The number of arguments I (mostly jokingly) had with physicists about how to do maths because they couldn't be bothered to do it correctly is _high_ 😂
For something like forensic statistics/probability, you would indeed want a statistician/mathematician. There are possible subtleties that their training is entirely focused on. A more serious issue is that they didn't want their name on it. If I were hired to write a report as devil's advocate, I'd either decline if there is nothing I could say in their defense or accept and write things that are true but selectively in the client's favor and make the conclusions qualified
@@LeoTheDarkAngel I think this is not a "basically," but an "actually.' Another comment marked for a year previous to yours said Dream admitted cheating months before that. (As in shortly after this video was released.) In regards to physicists, when an entire category of scientists like to begin sentences with "Assume..." they're going to ruffle math people's feathers, lol.
A reminder to people who might still be defending Dream after he admitted it was modded... even if it was actually an accident at the time of the run, he not only lied about it for three months, but went so far as to pay a professional mathematician to write a bogus paper defending him. And for anybody who tries to take the "final stand" of these sorts of things that it's not a big deal because it was just a game or whatever... someone who cheats and lies rarely does it just once. He's not worthy of trust, and if you keep giving it to him going forward, you're duping yourself.
I want to know at what point he noticed he had a mod on, because if he didn't notice the whole time he was speed running then its likely he might not have noticed it until after he had already had the mathematician write the paper. That would explain why he deleted his video about the subject and didn't say anything about it till just recently where he admitted to his fault. Usually people that lie don't come out and admit the truth especially if there is a large audience already defending them. The fact is he did not have to admit the truth people were still watching his content, he admitted because he wanted to. Frequent liars don't do that.
@@mesaplayer9636 "because if he didn't notice the whole time he was speed running then its likely he might not have noticed it until after he had already had the mathematician write the paper." No, it really isn't likely. If he hadn't noticed by the time that paper was written, there's no reason to think he would suddenly notice going forward; it's not like he still has the settings he used and is sitting there, staring at them. No: If, and this is a big if, he genuinely made an initial mistake, he would have noticed, at the latest, when the formal accusation had been levelled. "The fact is he did not have to admit the truth people were still watching his content, he admitted because he wanted to. Frequent liars don't do that." That's utterly backwards. Only frequent liars think that admitting the truth is a matter of transactional value, rather than basic morality. As for a motivation for admitting it now: When the dust settled and everybody had spoken their piece, the consensus outside of his fanbase was that he was a cheater, and even if that doesn't effect the numbers immediately, he has to consider his reputation going forward. This was a final attempt to save face when he realized the lie wasn't working well enough.
@@badlydrawnturtle8484 The speedrun moderators asked for his mod folder back when the controversy was still fresh and he gave excuses as to why he couldn’t give it to them. I’m sure he’s known for a good while now
@@mesaplayer9636 If he didn't know he had a mod, then why would he get someone to write a bogus paper? And you can say that the mathematician made a mistake, but then why would he remain anonymous? Every single person who takes pride in their work will put their name all over it, so he obviously knew he had a mod
@@badlydrawnturtle8484 The main reason he knew it was due to the mods was because the coder told him about it way after. At least according to Dream's statements.
A little bit of extra context: that 4th place run that Dream had was actually ON PACE for world record. He got to the end portal and, ironically, had bad luck with the number of pearls that were already in the portal. He then had to spend a few minutes scavenging the area for additional pearls. Good video Matt.
@@bruciex4574 yeah so the idea is, with modified weighted totals for these drops, he was set to get the world record at the time (I don’t know the specific details however it was by a significant margin). But when the time came to solidify the run, since these speedruns have so many factors and randomness involved, he was stopped by the randomness of the end portal itself since it included less than average pearls. Edit: it didn’t contain less than average pearls, but it did take awhile to find the extra pearl needed to complete the portal
@@bruciex4574 it’s also important to note for anyone not familiar with the process, the 6 streams identified included dozens of runs. It’s not just a one-and-done process. The pearls and rod drops are notorious as being run killers, taking up so much time doing something that requires no skill and all luck where the goal is to just be lucky. But obviously if you keep rolling a loaded die over and over again, it becomes more apparent.
@@bruciex4574 assuming the actual rates were changed or manipulated, it becomes more apparent the more you call on that same event. If you rolled a 6 sided die 600 times, for a fair die you would expect to roll a ‘6’ about 100 times. If instead you rolled it 600 times and had gotten ‘6’ 300 times, it would call into question the fairness of the die. If the die was indeed loaded, then that fact becomes more apparent.
I enjoy coming back to this one every so often because of how evergreen this video is. Despite being focused on what is now a years-old, and largely resolved, controversy, the core of what he's teaching us about throughout the entire thing is just as relevant today as it was then. The inherently suspicious nature of maths chaff, a simple tool of comparison for how likely a thing is in our universe, even simple things like how to understand scientific notation. It's a true masterpiece of a video, and the level of effort that must have gone into it really shines through. And not just because of the impossible shots he made in the background - though, every time I come back, I do wonder how the probabilities of the various shots he took match up to Dream's theoretical odds.
I feel most speedruns should have some sort of luck aspect, that's what makes it more engaging than just purely skill based. But the weight of the luck factor is just too much when it comes to Minecraft, in punch out the luck aspect is way lesser comparatively
@@arkayv well the whole reason people like more lucky speedruns is because it takes alot more skill to adapt to a luck based situation than to just memorize routes and inputs. That being said unfortunately its a hard balance, since if a game is not ENOUGH rng based, then it promotes a ton of resets, whilst on the other hand if theres TOO MUCH rng, it can be unfun to run and by extent watch. Its a very fine balance which i think minecraft handles well throughout its different categories. Random seed is more luck and set seed is purely skill.
*_They calculate every speedruns of Dream including those aren't top ones, (I didn't mean Dream DID IT) but Dream can actually equal it out with the higher drop rate on the top speedruns and low drop rate on fun speedruns to equal the percentage out._*_ (Sorry if I have any grammatical mistakes here, since I'm not a native English speaker.)_
This video is especially fun to watch after seeing the one with Hannah Fry on Bayesian statistics where Matt repeatedly fails to throw a ball onto a table. But now, he *very mysteriously* cannot miss a target! Also, the explanation of the math is superb.
There's something heartwarming about knowing you from Numberphile content 10 years ago, and still seeing you popping up with relevant content now. Feels like old friends from my childhood that inspired a lot of my passions growing up.
...why are people in the comments still trying to argue that Dream could have just gotten lucky? He admitted to having run on a modified client months ago.
From what I can tell, it's separated into two camps. Those who didn't know dream admitted to it, and those who know he admitted to it, but think there's still a case to be made that this COULD have been luck.
Weather he admitted it or not, the argument from probability is fallacious. If the video was about how he admitted it, it would be be a different story.
Doesn't matter if it's one in a million or one in a quinquadrigintillion. If there's any chance, there will still be be someone arguing that it's technically possible
@@pardeepgarg2640 yes, but probability still kinda applies... yea idk what im saying at this point, but either way, the point is that a ridiculously low probability is still effectively zero, even if "woOo iT's bIGGeR thAn ZeRo" :P
@@pardeepgarg2640 yes, basically its so unlikely to the point of implausability. For example, there is a non-zero chance that an alien from space will somehow abduct you and dissect you, but the chance of that is so damn tiny that it can be treated as zero.

The look of pride and satisfaction when he looked to see if he hit the bullseye and saw he finally did is priceless. Plus keeping up the level of expressive narration after that many takes is impressive in and of itself. Just genuinely impressed with this channel especially because I know you do another channel that's way more serious but I can't place atm.
Here's a kicker I haven't seen mentioned (probably because I haven't looked hard enough): modifying the loot tables is trivially easy. Minecraft natively supports datapacks and it's very easy to masquerade a datapack as vanilla (or, original to the game). People who have spent time writing Minecraft mods (myself included) have modified these configuration files quite a bit. It's more than the odds being practically impossible, it's the ease of which such cheating could have occurred.
But Minecraft's naïvety is part of its charm :D . It wasn't a game designed to be speedrun or played competitively. It's a sandbox, and so I'm glad they make modding so easy! (This coming from a vanilla player who doesn't even have Optifine haha.)
This is true. Especially when you consider that a lot of Dream's content has been based around Minecraft But... challenges that either he or his best friend coded themselves. He's familiar enough with Minecraft code to easily hide something that trivial.

Cause only one of them will willingly admit/defend when they bodge a paper.
this was a reason i gave to his rabid fans when i told them how research and finding reliable sources to work with is the best chance of dream being right
however it turned out dream literally just hired someone to do incredibly bad math and came from a wix website made a couple weeks prior to this event that still had its watermark of wix on it
Wrong. Never trust authority. Trust the rules of mathematics and read what they write, not who they are. Putting blind trust in people just because some university said they can put letters after their name is just stupid. And a cause of a lot of the issues we see in the world.
In the dream case , the mathematics is simple. You can work it out yourself with a calculator.
It's not enough for the scientist to put his name, considering all the potential conflict of interests in the real world, when it is not about Minecraft, but medical statistic justifying lockdowns or the lethality of a virus. In fact, I would say that only independend scientists are real scientists, everyone else is a scientific prostitute creating the numbers which are wanted by his clients. (the people who order the study to prove their ideology correctly)
Funnily enough, the scientist did redact the initial paper saying that there were alot of mistakes, mainly due to not understanding the game. Which makes sense. And btw he didn't want to put his name on the paper cause he didn't want to get public backlash from it, and lets face even if dream was innocent and the paper just proved it, he still would get alot of backlash. And in a time where having a job is so important and finding work is incredibly difficult think it's fair to want to stay anonymous to stop people calling for you to get fired, which does happen.
@@diekritischestimme That is certainly the case with "computer modelling", especially when modelling large-scale problems (like how a virus spreads worldwide). The problem is so complex, that you need to make lots of assumptions in order to make the problem calculable.

just for perspective, for the 10 billion human second century thing, it would have to take roughly 650.22 centuries for just a SINGLE occurrence of what happened to dream.
How did you work that out? (just curious have yet to take a class in statistics)
@@actually_tes1 it's actually just almost straight arithmetic at that point. The probability of getting Dream's result is about 1:2*10^22. The 10BHSC is about 3*10^19
By multiplying these two numbers (raw probability and number of attempts) you get a new expected value, which is something along the lines of 1:650 (1:666 with the numbers I just provided)
So you're going to need 650 of those centuries to expect it to happen once. Or alternately for attempts to be even faster. Or the population to be higher.
Well and if we factor in that it takes more than 1 second to do all the accounted livestreams it would take a couple trillion years for a single occurence. Considering the age of universe we still have a couple of trillion years to go.

@bobin the boggart The issue is that the Speedrun mods offered to hire a statistician to review their paper, but Dream said no specifically *because* the statistician would be biased in favor of their client. After the mods offered to choose a statistician that Dream agreed on, Dream declined. And then hired his own anonymous statistician. From a website that was created just months prior. With no page listing their employees, or even verifying their existence.
So it’s not simply that Dream hired his own statistician. The point is that he hired them *after* stating they would be biased.

It's interesting that he probably only increased his odds by a little bit, thinking it wouldn't be noticed, but forgetting that when you do things a lot of times, even a small increase in chances has a large statistical impact
Excel and taking simple data is so useful, it does make you see how incredibly impossible is what Dream has done
The funny thing is, the situation in which it *wouldn't* have a large statistical impact is ... the situation in which it wouldn't have any noticeable impact at all. Which, if Dream intentionally modified the game, would make that act of cheating kind of a waste of time - why bother if you can't even tell the difference?
I strongly recommend Karl Jobst's video on Dream's semi-confession. It's fascinating. There's a plausible theory that he had modified his Minecraft for practise and didn't know he was *still* using a modified version when he streamed. It raises an eyebrow but honestly he makes a compelling (and very nuanced) argument on the possible interpretations of what is now known.
Thanks for summarising this video for me
A slight increase in odds wont go noticed in a single run, the problem he had here was he kept using the mods run after run. In an unmodded game you're going to end up with extremely good luck and extremely bad luck in games. He effectively removed the bad luck games getting to his perfect game much faster and with less effort.

I think this is a lot like intelligent life. It is incredibly rare (by what we know) so it would be extremely unlikely for us to be here. But since we ARE here that kind of messes everything up.

@@RajasPoorna Depends on what other videos he was watching to make the algorithm feed him this one.
Dude holy crap. Like, I look at “getting 42/262 when 12/262 is the drop rate” and think “eh that’s lucky but doesn’t seem insane” until you actually do the math on it. That’s bonkers.
Yeah. The intuition that's important to have is that doubling the amount of trials obviously doubles the mean, but it doesn't double the standard deviation (how much we expect something to vary)
It only multiplies that by the *square root* of two.
So when if you have *four* times the amount of trials, you only get twice the deviation, even though the mean is four times as big. So suddenly this relatively small deviation (in absolute terms) becomes a completely unsurmountable mountain.
@@XCC23 I know you're right but intuitively it still feels like the odds should be similar to getting 4/26 when you expect 1/26.
Funny thing is, that same intuition is why we know about the cheating: the hacker knew they couldn't make things TOO lucky, but they used their intuition instead of crunching the numbers and they inadvertently made a change drastic enough to expose them.
What this makes me wonder about is how many other, smarter cheaters may be out there, manipulating game probabilities just by a standard deviation here and there, gaining an edge while maintaining plausible deniability.

Just a note on the odds on those craps runs because your math ends up off because of it.
The 154 roll streak was without crapping out (losing) *not* without rolling a 7. There could (almost certainly were) 7's in that run. It could have even been literally all 7's. The number for the losing roll varies depending on the phase of the game you're in.
One "game" of craps consists of one or two phases. You start with a "coming out" roll. If you roll a 7 or 11 you win immediately. If you roll a 2, 3, or 12, you lose immediately. If you roll 4, 5, 6, 8, 9, or 10 that becomes your "point" and you enter the second phase. In the second phase, you win if you roll your point number before rolling a 7 and lose if you roll a 7.
Thanks for clearing that up. I remember trying to learn how to play craps once and couldnt get my head around it, but it definitely was more complex than how it was described in the video
Wait, so they were counted as 154 rolls, which would be less than 154 rounds, right? And it sounds like every roll has a smaller chance of making you lose immediately than just "not rolling 7", so the real chances would be slightly higher than what Matt calculated.
Correction: a shooter's hand in craps doesn't end until the shooter sevens out. If they crap out, pass bets lose and don't pass bets win (except that don't pass pushes on a 12), but the hand continues. The actual probability of rolling at least 154 times in a single hand works out to be about 1.788 824 26 × 10⁻¹⁰, or 1 in 5 590 264 100.
If crapping out ended the hand immediately, the odds would be closer to those calculated in the video, since every roll would have either a 1/6 or 5/36 chance of ending the hand. Instead, it's either 1/6 or 0.

I know I am a bit late. But I love how, Matt gave Dream, the highest benefit of the doubt, by giving him 10 billion instead of the *calculated* 7.9 billion population (in 2021) and still Dream was orders of magnituted luckier than all of them.
Wouldn't have made a difference. The two billion extra wouldn't have changed the numbers in any meaningful way.
More than a benefit of the doubt, these numbers are ridiculously in Dream's favor. If 10 billion people each killed 305 blazes and made 262 barters every second of every day for 100 years, there is still only a 1/1000 chance that even a single person would have matched or beaten Dream's luck. Dream is but a single person playing over maybe a couple of dozen hours at most.
The population of the world is estimated. Maybe the estimate uses a calculation. But it's a bit misleading to say we calculated the actual population of the world and somehow got exactly 7,900,000,000
@@B3Band 7.9 billion and exactly 7,900,000,000 are completely different levels of precision. 7,900,000,000 plus or minus almost 50,000,000 is still 7.9 billion, but it is not 7,900,000,000.
That is because you guys haven't factored in the population of the lost city of Atlantis.
My Data class in University recommended this video for us to watch as to how to detect cheating. This entire story is hilarious, especially since he fought back against actual professors and used misleading data. He's such a textbook example of cheating, lmfao.
You should watch Karl Jobst's recent investigation into the digital papertrail of communication between Dream, the mods, the person he reached out to to make an analysis, the company that made the mod for his casual streams... There is a strong case that given the circumstances, he actually may be genuinely telling the truth about his fundamental defense of not knowingly using a mod that altered the drop rates.
The guy's behavior isn't "textbook." The amount of hours and money he poured into fighting the allegations, eventually caving in to try and stop the bleeding of his already tarnished irreparable reputation.

@@WJS774 I didn't understand that's why I'm asking 😔
@Princex69 Disclaimer: Not a MC player, I've just watched a few videos. Dream submitted a speedrun, speedrun was considered pretty lucky due to the drops needed to finish a run (Blaze Rods & Ender Pearls). People then started wandering if there was any foul play, countless MC players calculate the odds, astronomically high luck was needed for the speedrun. Dream hires a "mathematician" to disprove the accusations, he was asked to show his MC folders to show that he had no add-ons or mods installed, he was not able to show them due to some circumstances. Time passes and he "admits" that the run he submitted actually had mods installed to increase drop chances (Blaze Rods and Ender Pearls) but he did not know they were active. Plausible alibi, since he has said that he uses those for his other videos (Manhunt?). His run was then removed from the leaderboard. Apologies for any mistakes.

He's not worthy of trust, and if you keep giving it to him going forward, you're duping yourself.
I want to know at what point he noticed he had a mod on, because if he didn't notice the whole time he was speed running then its likely he might not have noticed it until after he had already had the mathematician write the paper. That would explain why he deleted his video about the subject and didn't say anything about it till just recently where he admitted to his fault. Usually people that lie don't come out and admit the truth especially if there is a large audience already defending them. The fact is he did not have to admit the truth people were still watching his content, he admitted because he wanted to. Frequent liars don't do that.

"because if he didn't notice the whole time he was speed running then its likely he might not have noticed it until after he had already had the mathematician write the paper."
No, it really isn't likely. If he hadn't noticed by the time that paper was written, there's no reason to think he would suddenly notice going forward; it's not like he still has the settings he used and is sitting there, staring at them. No: If, and this is a big if, he genuinely made an initial mistake, he would have noticed, at the latest, when the formal accusation had been levelled.
"The fact is he did not have to admit the truth people were still watching his content, he admitted because he wanted to. Frequent liars don't do that."
That's utterly backwards. Only frequent liars think that admitting the truth is a matter of transactional value, rather than basic morality. As for a motivation for admitting it now: When the dust settled and everybody had spoken their piece, the consensus outside of his fanbase was that he was a cheater, and even if that doesn't effect the numbers immediately, he has to consider his reputation going forward. This was a final attempt to save face when he realized the lie wasn't working well enough.
@@badlydrawnturtle8484 The speedrun moderators asked for his mod folder back when the controversy was still fresh and he gave excuses as to why he couldn’t give it to them. I’m sure he’s known for a good while now
@@mesaplayer9636 If he didn't know he had a mod, then why would he get someone to write a bogus paper? And you can say that the mathematician made a mistake, but then why would he remain anonymous? Every single person who takes pride in their work will put their name all over it, so he obviously knew he had a mod
@@badlydrawnturtle8484 The main reason he knew it was due to the mods was because the coder told him about it way after. At least according to Dream's statements.
A little bit of extra context: that 4th place run that Dream had was actually ON PACE for world record. He got to the end portal and, ironically, had bad luck with the number of pearls that were already in the portal. He then had to spend a few minutes scavenging the area for additional pearls. Good video Matt.
this seems like very important information, because why would you fake a failed run
@@bruciex4574 yeah so the idea is, with modified weighted totals for these drops, he was set to get the world record at the time (I don’t know the specific details however it was by a significant margin). But when the time came to solidify the run, since these speedruns have so many factors and randomness involved, he was stopped by the randomness of the end portal itself since it included less than average pearls.
Edit: it didn’t contain less than average pearls, but it did take awhile to find the extra pearl needed to complete the portal
@@bruciex4574 it’s also important to note for anyone not familiar with the process, the 6 streams identified included dozens of runs. It’s not just a one-and-done process. The pearls and rod drops are notorious as being run killers, taking up so much time doing something that requires no skill and all luck where the goal is to just be lucky. But obviously if you keep rolling a loaded die over and over again, it becomes more apparent.
@@schishwah3754 just to be clear, with "loaded die" you're talking about the change in ender pearl drop rates because of pearl stopping, right?
@@bruciex4574 assuming the actual rates were changed or manipulated, it becomes more apparent the more you call on that same event. If you rolled a 6 sided die 600 times, for a fair die you would expect to roll a ‘6’ about 100 times. If instead you rolled it 600 times and had gotten ‘6’ 300 times, it would call into question the fairness of the die. If the die was indeed loaded, then that fact becomes more apparent.
I enjoy coming back to this one every so often because of how evergreen this video is.
Despite being focused on what is now a years-old, and largely resolved, controversy, the core of what he's teaching us about throughout the entire thing is just as relevant today as it was then. The inherently suspicious nature of maths chaff, a simple tool of comparison for how likely a thing is in our universe, even simple things like how to understand scientific notation. It's a true masterpiece of a video, and the level of effort that must have gone into it really shines through.
And not just because of the impossible shots he made in the background - though, every time I come back, I do wonder how the probabilities of the various shots he took match up to Dream's theoretical odds.
You know I was trying to understand why I keep coming back to this video. Now I know.
Same. :)
Well said
"I like to watch games that aren't as random and are more skill based like Mike Tyson's Punch Out"
*Summoning salt viewers have entered the chat*
... *bwaaaaaammmmmmm*
I lol'd at that part cause a lot of punch out speedruns are luck based too
I feel most speedruns should have some sort of luck aspect, that's what makes it more engaging than just purely skill based. But the weight of the luck factor is just too much when it comes to Minecraft, in punch out the luck aspect is way lesser comparatively
@@sanhakim1335 All those random delays...
@@arkayv well the whole reason people like more lucky speedruns is because it takes alot more skill to adapt to a luck based situation than to just memorize routes and inputs. That being said unfortunately its a hard balance, since if a game is not ENOUGH rng based, then it promotes a ton of resets, whilst on the other hand if theres TOO MUCH rng, it can be unfun to run and by extent watch. Its a very fine balance which i think minecraft handles well throughout its different categories. Random seed is more luck and set seed is purely skill.
It was Dream's big picture all along, he wanted to teach the young people statistics

Eeuuuuggghhhhh
@@The_SOB_II Its a joke its a joke xDD
This was very well done. I never realized he was more likely to get NO ender pearls than that many.
*_They calculate every speedruns of Dream including those aren't top ones, (I didn't mean Dream DID IT) but Dream can actually equal it out with the higher drop rate on the top speedruns and low drop rate on fun speedruns to equal the percentage out._*_ (Sorry if I have any grammatical mistakes here, since I'm not a native English speaker.)_
This video is especially fun to watch after seeing the one with Hannah Fry on Bayesian statistics where Matt repeatedly fails to throw a ball onto a table. But now, he *very mysteriously* cannot miss a target! Also, the explanation of the math is superb.
There's something heartwarming about knowing you from Numberphile content 10 years ago, and still seeing you popping up with relevant content now. Feels like old friends from my childhood that inspired a lot of my passions growing up.

...why are people in the comments still trying to argue that Dream could have just gotten lucky? He admitted to having run on a modified client months ago.
From what I can tell, it's separated into two camps. Those who didn't know dream admitted to it, and those who know he admitted to it, but think there's still a case to be made that this COULD have been luck.
@@NickersonGeneral No, that's impossible.
@@grondlegger939 reread the comment 🤦♂️🤦♂️
We should be doxxing dream and trashing their home for this.
Weather he admitted it or not, the argument from probability is fallacious. If the video was about how he admitted it, it would be be a different story.
Math: this guy is 10 billion times luckier than the luckiest gambler
Dream stans: ITS STILL POSSIBLE A 1 TRILLION CHANCE IS STILL POSSIBLE!!!
Doesn't matter if it's one in a million or one in a quinquadrigintillion. If there's any chance, there will still be be someone arguing that it's technically possible
@@juliaf_ ... But quantum physics forbids this! /s
@@pardeepgarg2640 yes, but probability still kinda applies...
yea idk what im saying at this point, but either way, the point is that a ridiculously low probability is still effectively zero, even if "woOo iT's bIGGeR thAn ZeRo"
:P
@@pardeepgarg2640 yes, basically its so unlikely to the point of implausability.
For example, there is a non-zero chance that an alien from space will somehow abduct you and dissect you, but the chance of that is so damn tiny that it can be treated as zero.
@@juliaf_ the number is too large to realize how incredibly small and minuscule for it to happen
this is like lottery players reciting that same chance to win the lottery and not realize how the odds are way way way too large to happen where you actually win the billion dollars they have in stock
The look of pride and satisfaction when he looked to see if he hit the bullseye and saw he finally did is priceless. Plus keeping up the level of expressive narration after that many takes is impressive in and of itself. Just genuinely impressed with this channel especially because I know you do another channel that's way more serious but I can't place atm.
Here's a kicker I haven't seen mentioned (probably because I haven't looked hard enough): modifying the loot tables is trivially easy. Minecraft natively supports datapacks and it's very easy to masquerade a datapack as vanilla (or, original to the game). People who have spent time writing Minecraft mods (myself included) have modified these configuration files quite a bit. It's more than the odds being practically impossible, it's the ease of which such cheating could have occurred.
But Minecraft's naïvety is part of its charm :D . It wasn't a game designed to be speedrun or played competitively. It's a sandbox, and so I'm glad they make modding so easy! (This coming from a vanilla player who doesn't even have Optifine haha.)
This is true. Especially when you consider that a lot of Dream's content has been based around Minecraft But... challenges that either he or his best friend coded themselves. He's familiar enough with Minecraft code to easily hide something that trivial.
Up you go good person, it's very important to keep this in mind.
Just saying, if it is dream, he would go above and beyond to achieve sth. Even if it's hard, he would have found a way to modify the game lol.
He proved that there weren’t even any data packs
The quarantine beard doe...
Damn Flammy quick af
Growing out a beard might not be a good idea depending on what masks you're usually wearing when going to public places.
FFP2 masks rely on your mask being sucked towards your face when you breathe, so heaving something like a beard between your skin and your mask greatly diminishes the mask's effectiveness.
Or at least that's what I've read in the newspapers, I'm not an expert.
@@ler6118 you should hire an astrophysicist to calculate the odds of the mask not having a good *_SUCC_* if the beard == TRUE
