But this is not science's fault, nor is it a conspiracy of the medical system. The scientific method is limited in its ability to give us data. Yet, practically we need to understand the world. The only way out is innovative methods that people can actually understand their pros and cons and get published without trying to immitate the scientific methods to be listened to. Oh, and developing the right hemisphere science. Which is what I experiment with.

They actually steal and collect it for their own records because of the following reasons: 1. They think that these are valuable intellectual property which should only belong to them. Hoarding basically 2. They will pass it off as their own intellectual property subsequently in a post apocalyptic era or a different realm 3. Being intellectually retarded, they prefer quantity over quality. More the better 4. They are basically mining your intellectual property by exploiting you for their use 5. Commercial reasons just in case your papers somehow fetch money This is actually good. You should publish more crap for the slavemasons to prevent then from getting hold of some actual research

As a former grad student, the real issue is the pressure universities put on their professors to publish. When my dad got his PhD, he said being published 5 times in his graduate career was considered top notch. He was practically guaranteed to get a tenure track position. Now I have my Masters and will be published twice. No one would consider giving you a post doc position without being published 5-10 times, and you are unlikely to get a tenure track position without being published 30 or so times. And speaking as a grad student who worked on a couple major projects, it is impossible to be published thirty times in your life and have meaningful data. The modern scientific process takes years. It takes months of proposal writing, followed by months of modeling, followed by months or years of experimentation, followed by months of pouring over massive data sets. To be published thirty times before you get your first tenure track position means your name is on somewhere between 25-28 meaningless papers. You'll be lucky to have one significant one.

It’s almost impossible to publish negative results. This majorly screws with the top tier level of evidence, the meta analysis. Meta analyses can only include information contained in studies that have actually been published. This bias to preferentially publish only the new and positive skews scientific understanding enormously. I’ve been an author on several replication studies that came up negative. Reviewers sometimes went to quite silly lengths to avoid recommending publication. Just last week a paper was rejected because it both 1. Didn’t add anything new to the field, and 2. disagreed with previous research in the area. These two things cannot simultaneously be true.

As someone who studies theoretical statistics and data science, this really resonates with me. I see students in other science disciplines such as psychology or biology taking a single, compulsory (and quite basic) statistics paper, who are then expected to undertake statistical analysis for all their research, without really knowing what they're doing. Statistics is so important, but can also be extremely deceiving, so to the untrained eye a good p-value = correct hypothesis, when in reality it's important to scrutinise all results. Despite it being so pertinent, statistics education in higher education and research is obviously lacking, but making it a more fundamental part of the scientific method would make research much more reliable and accurate.

Observational studies in the social sciences and health sciences are mostly garbage. People who don't do experiments or RCTs need to study a hell lot of statistics to get things right. And only recently we got natural experiments to help us with good research design for those areas. Until my masters, I was relatively well trained in traditional statistics (I'm an economist) but unaware of natural experiments. I was completely disheartened about how awful my research was, given that different specifications in my observational studies were giving me different results. I only gained renewed enthusiasm in a much better quality PhD who taught me much better research designs.

Don't forget something Derek left out though. Re-sampling fixes a lot of these issues. Run a sampling test including replications to get your standard deviations and get a p-value less than 0.05 (or even better, less than 0.01 or 0.001). Then rerun the sampling tests multiple times to see if you can repeat the p-value. THEN (most importantly) report ALL your experimental runs with p-values. If even one out of (at least) three to five separate independent runs has a non-significant p-value, consider the entire study with a huge pinch of salt. Most reputable journals though nowadays insist on this - the peer reviewers worth anything will at the very least.

John Ionnadis has conducted "meta-research" into the quality of medical research and concluded that most medical research is severely flawed---in fact, "80 percent of non-randomized studies (by far the most common type) turn out to be wrong, as do 25 percent of supposedly gold-standard randomized trials, and as much as 10 percent of the platinum-standard large randomized trials." Wow. There are also problems with dealing with complex systems, and with challenging scientific orthodoxy into which some scientists have invested their entire careers.

I just *knew* John Ionnadis would come up here. If you want to see "mostly wrong", take a look at his record on COVID-19 predictions-off by two orders of magnitude. His sensationalized contrarian kick has gotten people killed. There are many better, more thoughtful critics of the state of research. I'm not saying he's always wrong. But he does go for the sensational, and is often sensationally wrong, and doggedly so. A lot of progress has been made, especially in medicine, with pre-registration of trials, data & code repositories, etc, and I'll give him credit for helping kick-start some of that. (Preprints seem to me to be a move simultaneously in the right and wrong directions!) But statements like "80% of non-randomized studies turn out to be wrong" isn't even well-defined enough to be falsifiable. It's a non-scientific statement. And meta-research, like meta-analysis, is itself extremely subject to selection bias. Each need to be approached with great care and skepticism. A lot of what he says is not controversial. I'm not here to demolish John Ionnadis, but to urge people to steer clear of his broad sensationalized generalizations, and look carefully at the arguments he makes. Apply the same critical standards that he urges to his own research. Sometimes the kettle calls the pot black-but black is still black.

You should have used an approach developed in cybersecurity research long time ago for the same issue: notify the authors that in 3 months you are going to publish your findings about all their mistakes no matter what they do. Then the authors have 3 months to retract their papers on their own and/or correct them. This solution is called "responsible disclosure" of vulnerabilities. You see, in cybersecurity the problem of "nobody listens unless you publish" has been acknowledged a long time ago. You can do this anonymously as well: from my experience, scientists are not more ethical than average human, and when you threaten their career and self-image they quite often freak out and try to hurt you back by all imaginable means -- just as many normal humans would in such a situation.

P values of 0.05 are a joke. Look, I'm going to sound biased, and that's because I am. This is a much bigger problem in fields like Psychology than in fields like Physics. The emphasis on constant publication and on positive results is still a massive problem. Researcher bias is still a massive problem (although still, not as much as in Psych/Sociology). The existence of tenure helps a little since researchers become able to research whatever they want rather than what the system wants. But we aren't claiming world-changing discoveries with P=.05. Derek brushed right past this like he was afraid of sounding biased but I'll repeat: 5 sigma is a 1 in 3 million chance of getting a false positive purely by chance. Every physicist "knew" the Higgs had been discovered years before we finally announced it and started celebrating. But we still waited for 5 sigma. I did some research with one of my Psych professors in my freshman year. She was actually quite careful outside of the fact that her sample sizes were pathetic. We went to a convention where we saw several dozen researchers presenting the results of their studies, and it was the most masturbatory display I could have imagined. There were some decent scientists there, no doubt, but the *majority* of them were making claims too grandiose for their P-values and sample sizes, confusing correlation with causation, and most of all *failing to isolate variables.* If a freshman is noticing glaring problems in your research method, your research method sucks. The next year I had a Physics prof. who had a friend of mine and his grad students run an experiment 40,000 times. There is no comparison. We need a lot more rigor in the soft sciences than we have right now. Mostly because science. (But also because they're making us all look bad...)

And there's also the problem that experiments might be difficult to perform in fields outside physics. It can expensive and it requires a lot of planning and logistics. Not to mention that ethical dilemmas might stand in the way, which happens a lot in medicine. In a way, the physics field is blessed by not depending on studying people, and overall physics experiments are cheap; expensive particle accelerators non-withstanding. One thing I think Derek missed is to emphasize that one shouldn't be looking at single studies anyway. You look multiple studies for trends and toss out the flawed ones and the outliers. Or even better, look for meta studies. I'm also unsure if changing your model / what you measure *after* you have looked at the data is p-hacking. Such a mistake seems way more serious to me, as you're basically making your model fit a specific data set. Give me any data set and I can make a polynomial fit all the points. Basically, reusing the data after changing the model should be a crime :)

As a researcher, I find those numbers very conservative, even when I'm 4 years late to the video. I also feel like there's a reason missing for the false-positive results category which is a deviation from the main objective. Some true positive results shouldn't be considered as such when you make an in detail analysis of their methods, statistics and final findings just for the pure reason that, mid-study, some parts of the objetive were changed to accomodate the findings. This is also an issue that pisses me off, especially in my research field where there's such a huge mix of different scientific areas that it's next to impossible to verify anything at all in detail because everyone just pulls the results their way. As some people already mentioned here, some authors do withold critical pieces of information for citation boosts. If people can't reproduce something from a study, they can neither be proved wrong by the paper's information alone (as long as it checks out in theory) nor can they be denied autorships and citations from other papers which effectively boosts their 'worth'. The fact that researchers are evaluated using citations/autorship numbers is also one of the leading problems as to which false-positives exists in such large numbers (I don't believe false-positives are only ~30% for a damn second, but this is my biased opinion) and why some papers, even though everything checks out in theory, can never be truly reviewed on a p2p manner on the practical results sides of things. Anyone who works in research knows there's a lot of... misbehaving on most published works, regardless of the results. Therefore I have to disagree with the fact that researchers are fixing some of the problems. It's not that we don't want to fix them, but because the system itself, as it stands, is essentially rigged. We can sift through p-hacked results. We can't, however, sift through p-hacked results if the objective is mismatched with the reported findings (if someone told me that was involuntary, I'd believe them because I know how easy it is to deviate from it) nor from a paper which withholds critical information. And the worst part about it is that this is further fueled by higher degrees thesis such as masters or PhD's where it's mandatory to cite other people for their work to be 'accepted' as 'valid'. You have to approach published works with a very high level of cynicism and with some time and patience on your hands if you're even dreaming of finding a published work that remotely fits your needs and actually shows a positive result on most scientific areas.

This reminds me of in college trying to find trends in data by any means possible just to come to a conclusion that would result in a good research grade. I think when your motivation becomes solely about money or grades (or whatever other comparable unit u might think of), you lose sight of the actual purpose behind what you're doing. In my case, because of my fear of getting a bad grade, i twisted the research process to show results that would impress my teacher, but which ultimately were false and useless. This video made me realize how many systems (in education, business, science) are actually structured for their participants to waste their time pursuing arbitrary goals rather than the ones which are actually valuable. If we could make it so a thorough and honest process would be rewarded just as well as one that has a flashy result then we would have a lot more true value being generated via these systems. This has been on my mind in school recently so I'm really curious to hear what others think if anyone wants to reply. Great video!

@Jake122206 жыл бұрын
His point was simple, the rewards for being able to show the desired results are better than for getting less desirable results within these systems. In all these feilds if you can show the desired result (regardless of if the results are valid) then you get better rewarded, be it grades, promotions, bonuses or publication. While in most scientific feilds most errors would likely be accidental bias, in areas like testing diet supplements or doing studies funded by corporations these are well known deliberate issues. Unfortunately most people have a very poor grasp on statistics and for that matter the scientific process so it's all too easy to make a lot of people believe false data. We really do need to improve the systems at all levels. There are currently moves to make things better, but we will continue to have these problems for a very long time, especially with journals not publishing studies that show other studies to be wrong and publishing studies that didn't pre submit their methods of evaluation before commencing.

It's also changed a bit for them now that they have to have conclusions that at least have SOMETHING to do with the data collected. There was no requirement for that before, as I understand it.

The point about discouraging replicating dubious-or any-studies is important. There just aren’t incentives to duplicate or refute someone else’s findings, but rather come up with something ”original”. On a similar note, as an engineer who frequently volunteers at elementary - high school science fair judging, I’m constantly dismayed at the emphasis that other judges-both somewhat “lay” and professional STEM judges-place on “originality”… at the elementary & middle school level, even, not to mention the high school level! (Ok: maybe a district or regional winner at HS needs to be decently original, but…) Many people place originality and presentation skills (not to be entirely discounted, of course, but still not #1) above scientific inquiry, larger data trials, strict controls, and even just a good, solid use of the basic fundamentals of an experience by as taught in elementary science class.

@@whatisahandle221 I believe that in experimental physics it is customary to publish independent replications of breakthrough studies in comparatively high-impact journals (as well as to cite replication studies along with the original ones in future papers). Sadly this is more of an exception that proves the rule. In life sciences on the other hand there are so many subfields and so much competition, that far too many "original" yet shoddy papers (methodologically speaking) get published. My subjective impression is that this problem is slightly smaller in niche and/or "old-fashioned" subfields, where the odds of getting a reviewer who knows all the ins and outs of the topic are relatively high.

This is gold. It is like playing 4D chess with your own brain. With every agreement and disagreement with your own intuitions, you fall into the trap of asking the perpetual questions of "what if my bias is the bias showing me others' bias, and what if that itself is some bias or error in judgement I fail to consider." This becomes too much and can throw people (myself) off, into a spiral of extrapolating truth. I suppose the remedy of bias is not only itself recognizing bias,but is perhaps the understanding of updating beliefs based on a consistent or more reliable framework such as Bayesian Thinking. So, I do think beginning with investigating biases and attempting nuance by finding multiple sides to research or a thought, is a starting point. It is tiring playing mental chess and questioning yourself, however, it does sometimes provide some insight is getting closer to truth. It also makes it easier to detach ideas when new information is presented. Well, that is my mental state. It might be a bias of its own :). If we are emotionally invested in an idea, consciously or subconsciously, we tend to be more inelastic to new and valid evidence that doesn't support our intuitions. These are just my observations and of course, given valid criticism, I shall update them. :)

And this is why the method exists. When in doubt, test it yourself, never rely on trust or opinion, even your own. This is the most important part of it all, as multiple independent tests reduce the bias. This is why when gauging any studies, you must look for indepenent confirmation: a single study can always go wrong in subtle ways. Even the methodology could be wrong, and then while it gets confirmed by others, different studies on the same subject cast a different light on it. The more studies, the more confident you can be. Evidence over opinion.

Derek, I am convinced that the whole reason for this reproducibility problem is money. Unfortunately, science/academia is run like a business. Profit is key. Journals need to make money, institutions need to make money, funding agencies need to convince the rest of the world that the tax dollars spent on scientific research are well spent - and that means results, tangible results. So the scientific effort is reduced to the production of results - as much and as fast as possible. This creates a very destructive pressure on the researcher. I'm a graduate student currently working towards an academic career. I have been told by several profs in my field including my advisor that if I want to get a faculty job at a good institution after finishing my phd, I need to have at least 8-9 papers in my CV with at least 2-3 in a high impact journal. The reason is, of course, the sheer amount of competition; there are huge numbers of applicants and very few open positions. When hiring researchers, universities look at their previous research i.e., papers - and people can count much better than they can read. As a grad student, you can dedicate your 4-6 years to one fundamental problem, work on it rigorously, and -if things work out- end up publishing one or two papers with a huge impact on the field. But when you then go looking for jobs, you'll have trouble because people can count better than they can read. They'll say "Oh this guy only has 2 papers but this other guy has 15, let's hire the other guy." I know a lot of people in this situation - extremely bright grad students who cannot get faculty positions or even decent postdocs because they don't have enough papers in their CV. Many grad students who intend to stay in academia are aware of this, and there is no way you can publish at least 8 papers in 4-6 years without sacrificing rigor and/or reproducibility. Sorry for the long comment, but this is something that constantly bothers me and I felt a need to say something. Hope you get a chance to read this, I'd be very interested in what you think.

Real-world systems can never be broken down into a graph of sub-systems with known relationships. Weather or human body, or economy are such systems which cannot be completely decomposed into elements. They are like systems of equations where variable A depends on B, C, D, and each variable depends on the others, in non-linear way. It works as a complete system, we see that it works, but if you start decomposing it into elementary things, they won't add up back, mainly because you just can't standardize (tie one fact to the other) nor detect all of system's elements.

Aleksey Vaneev Nono, they absolutely can, but not with Cartesian and Euclidean modelling. The real world is not made that way; it's an incommensurate system which behaves in a fractal sense. There are numerous elements at one scale that cohere to make a compound element have more presence at a larger scale. The standard mathematical systems require relative coordinate logic, which works on paper, but causes all of the apparent problems that we all face in the world of things not adding up. If you don't know, Cartesian mathematics is working with x,y,z graphing, and Euclidean math starts with a point (you just decide where it starts) and then a uni-directional line. Reality works with bi-directional curved lines (spiralling into a hypotrochoid), as described in Newton's Third Law: recoiling inertia. All things in reality behave this way. You can't divide something that does not have Cartesian dimensionality. The primest example is a magnet. If you chop a magnet in half anywhere, it will immediately form 2 fields that have identical geometry to the original, with N/S and inertial plane. You have to work from the bottom up, figuring out how the thing itself works before you can make any assumptions on how complex constructions using this thing works (even if you know how to use it, doesn't mean you know how it works fundamentally).

Exceeding that strain, while still below the breaking strength, will result in weakening of the material with repeated use causing failure below it's published minimum strength. E.g. steel might have a tensile strength of 110,000psi but a fatigue strength of only 63,000psi (63ksi/110ksi = only 57.27%). So, for conservative use, most industries require robust safety factors to account for fatigue, use, damage, etc. Commercial airliners are rated for +3.0g x 1.5 safety factor at maximum weight. Bridges vary, depending on seismic requirements, etc. But it's not a good idea to cross an old country road bridge rated for 6 tons, with a 12 ton vehicle. You might survive, but the bridge will be damaged.

The problem Veritasium exposes in this video is the same thing Richard Feynman spoke about during a Cal Tech speech that was published in his book "Surely You're Joking, Mr. Feynman." Richard Feynman spoke about Cargo Cult Science; which comprises practices that have the semblance of being scientific, but do not in fact follow the scientific method. In his speech, Feynman said, "We've learned from experience that the truth will come out. Other experimenters will repeat your experiment and find out whether you were wrong or right. Nature's phenomena will agree or they'll disagree with your theory. And, although you may gain some temporary fame and excitement, you will not gain a good reputation as a scientist if you haven't tried to be very careful in this kind of work. And it's this type of integrity, this kind of care not to fool yourself, that is missing to a large extent in much of the research in cargo cult science." It pretty much sums up the problem within the science community. The lack of integrity as a scientist, largely influenced by the lack of freedom given to scientists at select institutions, is the downfall to most careers in science and scientific research. Feynman ends his speech by giving the students much needed advice on how to be a better scientist by saying, "So I wish to you-I have no more time, so I have just one wish for you-the good luck to be somewhere where you are free to maintain the kind of integrity I have described, and where you do not feel forced by a need to maintain your position in the organization, or financial support, or so on, to lose your integrity. May you have that freedom." I could've have said it better!

Thank you for posting this! I'm often commenting on people's sycophantic acceptance of anything scientific. I try to point out that science is not about accepting wholesale the word of authority figures, but about being skeptical. Testing the world around you, and doing so in a way so as to limit your biases. The way some people rush to defend their favorite scientists or pet theories has prompted accusations of cult like behavior from me on a number of occasions. It's nice to hear such a man as Feynman speaking out about this. Of course I'm talking more about the lay persons blind acceptance of anything handed down on high from what they perceive as a high priest in the 'cargo cult'. The kind of person who parrots what they hear on NPR or PBS with _zero_ understanding of what they're talking about. You know this person, they wear a NASA t-shirt and are quick to comment on the fundamental nature of the universe despite receiving a 'D' in high school physics. They watch the Big Bang Theory and laugh along merrily. They have conjectures on the nature of black holes yet struggle to calculate a fifteen percent tip on their bill. They have a wealth of scientific and pseudo-scientific "fun facts" but no integrated understanding of any of it. You'd be hard pressed to find a single original thought floating around in their brain. These people are the tributaries of the 'cargo cult' of science. And unfortunately they represent the majority of people who are at least interested in science. It's their votes the government counts on when allocating money to scientific institutions. It's their views the little pop science videos all over youtube count on for their ad revenue. None of these institutions are interested in actually teaching their tributaries how the scientific method works, the value of skepticism, or a groundwork understanding of the subjects they claim to love so dearly. Long story short, the cult priests need the tributaries as much as the tributaries need the priests. And it's not going to end anytime soon. The only solution is to educate yourself. An undergraduate understanding of mathematics, and at least a conceptual understanding of some of the models we use in physics and engineering take hours of work but if you love these subjects put the work in and learn them. Most importantly, understand _what a model is_ and _what their limitations are_ . No real scientist claims to have a complete and true understanding of how the universe works! We do however have some _amazing models_ we can use to predict how the universe will behave. TLDR: Don't be a cult member. Don't take people's word for it. Put the work in and learn it for yourself!

It's not that scientists are put in positions where they are forced to surrender their integrity, it is their _willingness_ to surrender their integrity. Integrity holds little value for many people. Notoriety, money, prestige, security - these things are esteemed higher than integrity. Integrity should be of infinite value but, alas, human nature is such that integrity is bought and sold and many times simply given away.

I remember the chocolate study. It may have been this one or a similar one being done about that time. I was a potential candidate for testing. However I turned it down when I was told they would be taking deep tissue samples... not by a nurse but by a 'Trained Technician', and not in a medical facility, but in a rented room at the local university. Those red flags were enough for me to tell them no, and to keep their $600 and the portioned food they were going to give me for my meals. I was poor as heck at the time and barely scrapping by. Still having a non-medical person digging into my body for samples was not better then ramen again for dinner.

It should be in British English, but not American English. Research is a collective noun which American English treats it as a singular noun, so "is" is the correct verb. British English treats collective nouns as plural, so in its grammar rules you are correct. If the sentence was about "Published research studies" the verb would be "are" in both. I know Derek is Australian-Canadian, so I don't know which rule applies in Australian or Canadian English, but apparently in this case Derek subscribes to the American English rule.

In the social sciences, the problems extend into qualitative studies. Qualitative studies are known for relatively small sample sizes (of often hand-picked participants) and researchers aren't obligated to disclose any data other than what they decide to display in the write-up of the study/article. They can tell whatever story they want to tell about how they collected and analyzed their data and there's almost no way to verify it. A researcher could look through 500 pages worth of interview data, for example, and only pull quotes from 2 pages worth of carefully selected text to craft an article. Essentially, a dishonest qualitative researcher can produce any type of conclusions they want to and even honest qualitative researchers doing the best job they can are frequently just publishing the point of view their favorite theory is already driving at. I've seen entire qualitative studies that hinge on one story from one participant and the rest is merely filler.

IMHO, qualitative research is an oxymoron. I had long debates with nursing professionals who conducted "qualitative researches", basically writing down "narratives" and ethnographies; i.e. things patients and nurses had said. They adamantly refused to say they would generalize from these results because "that's science". We're not doing science." Me" "So what value does this have?". Answer" Oh we might learn something from it. Someone might have a similar experience". They get funding for this, and it enhances their career. They ask doctors to put their names on it and the doctors say "Sure" because they need thier names on publications

My 30 year experience of virology and immunology (a more objective bit of biology) is that the data are generally OK but they don't mean much (or anything really) because they use model systems toio artificial to translate to real life.

I think that in many fields, it's understood that much of the research seen in journals is dubious. They've known that since they were in graduate school. They accept that.

Reporters have no feel for what conclusions are spongy, and which have really broad, firm acceptance among the experts in that field.

You can design a circuit, model it in software, have your peers review it, take all kinds of steps to eliminate risk, but in the end you have to apply power and let mother nature decide if you were right or wrong. I have to say that a majority of the time there was a mistake or two in the first prototype.
