P-hacking is just the start of it. It could be reduced a great deal if scientists had better education in statistics and data analysis. Amazingly, very few do. Very few understand the assumptions that go into calculating a p value, or know what a chi-square statistic is, or understand that not all distributions are Gaussian so your p-value may be a massive underestimate, or understand the role of correlations, etc. But that wouldn't eliminate the many other problems that come, at least in part, from journals' overwhelming profit motive and from researchers' incessant pressure to publish, no matter what. As others have said, you get the behavior you incentivize. I've personally observed all of the following: -Guest authorships for people who had little or nothing to do with the research (I suspect a majority of papers have this in some fields) -Scientists who were instrumental in designing/conceiving the experiment getting cut out so that the remaining authors can get larger shares of the credit (this has been done to me and to many of my colleagues many, many times; these days, I expect it.) -Big-name authors being able to push an article through peer review despite an unambiguous rejection by a reviewer or even multiple reviewers (again, on multiple occasions; the problem seems to be worse with bigger-name journals) -High-quality, well-supported research results being considered unpublishable just because a journal editor doesn't think it's going to sell a lot of subscriptions (this is normal; it happens to probably more than half of journal submissions; remember that a journal's job is not to promote science but to make money) -Papers getting published in respectable journals with such absurdly obvious basic flaws that an undergrad should be able to immediately see why they're bogus (we're talking perpetual motion type stuff; just ridiculously silly ideas) -Big-name professors attaching themselves to already-successful projects and then taking credit for them, using their platform to convince the world that they invented the thing when they don't really even know how it works -Scientific conferences at vacation resorts where everyone is an invited speaker but no one has their fees covered, i.e. just blatantly selling invited speakerships to bogus conferences in league with resorts (and plenty of scientists willing to pay to play that game, using taxpayer money) All this in a world where, at least for technical articles, Wikipedia is a more reliable source than Science or Nature. Getting published in a big-name journal means that it's flashy, not that it's likely to be true. In a world with millions of scientists, the incentive structure practically guarantees this behavior. The system is deeply, deeply flawed. And yet it still seems to kind of work. On the whole, the scientific enterprise shambles towards the truth, 100 steps forward, 99 steps back. Because even in the midst of all this I've met plenty of extremely intelligent, dedicated, rational, hard-working scientists who just want to get at the truth whatever it is. On another note, I miss conferences...can we be done with this pandemic already?

Almost all research is biased. Any scientific peer-reviewed study you look at is created to self-servingly boost careers, sell products, or to push an agenda. That's right, science is corrupt, just like everything else humans do. It is the reason we are not a Scientocracy or a Technocracy. There are some exceptions, such as a company doing research for it's own private use, that is less likely to be skewed by bias.

Click bait. Show me a single chemical synthesis paper with an alpha or beta error. Doubtful. You should have made it more apparent that it involves statistics and not using statistics correctly. PhD’s have too little training in statistics. I love ur channel, but in this one you botched it. Please don’t feel badly; everyone else has, too. Now get out there in please make me more of your incredible videos. You are a breath of fresh air. And, if I could give you an award, it would be for being one of the best human beings alive today.

"Let's assume that 10% of them reflect true relationships and the rest are false." Why would we assume that? I'm not saying he's wrong, but how did he come up with those numbers- research, just an example, or a shot in the dark? And if it was research, can we trust it?

This confirm my feeling about research, be it in cosmology, quantum mechanic, relativity or medecine.There is unfortunately such a misunderstanding ofstatistic and statiscal results or manipulation of statistical results (vanitas vanitatum ed omnia vanitas and greed) that the mainstream public including scientists gobble everything. See the way STATINS sellers and promoters used their initial studies "36 per cent less deads from cardiovascular events" because the death rate move from 2 per cent to 2.72 per cent in their double-blind experiments (.when all life-biology researchers can show everybody how cholesterol, a building bloc of many proteins-enzymes is a major necessity for human life) They had better to find a better real drug really dissolving harmlessly the arterial plaques instead of reducing the stock of cholesterol on board of a "compensating" regulated by life (so misunderstood as so complicated), body..

I believe that the great danger with science as we know it, is that it tends to make us throw away our intuition, believing that we can trust our test results blindly. As we can see we can´t... By the end of the day we often depend on our intuition for making good decision, as scary as it may seem. Great vid!

The solution to that is you repeat the tests. If you keep getting unlikely confirmations then a pattern can seem more significant - but can it ever be proven? Before you discount all correlation though, ask this. If correlation doesn't imply causation, what does?

We do need to change how we publish and fund and incentivize science. The hunt for originality is hurting science. The incentives system is obsessed with staking claims on new territory. Funders, editors, employers all care about finding the next glorious breakthrough, with no regards to how many false positives it costs them to get there.

Brilliant conclusion. If scientists, who know what they are doing and understand the limitations and biases still get it wrong more often than we'd like, the people who don't actually know what they're talking about (even if they think they do) and are not aware of the biases (or think they are above them) get it wrong much more often. Considering the public (and many leaders) seem inclined to follow the latter instead of the former, humanity is circling the drain.

About all these stupid climate change comments (which isn't even the same thing as what he talked about, since these unreproducible studies don't have hundreds of thousands of data points collected about them all the time everywhere in the world, which makes climate change closer to basics physics, that anyone can observe patterns and study it, unlike these studies that are so specific to the one thing they studied, so never get reproduced) It seems like most of the commenters didn't take this video to be "we need to reproduce studies to get more sure about things". It seems like they have taken the video to mean "if science doesn't support my worldview, it's unreliable. If it does, I'm gonna use that as evidence for my opinions" And it's funny too how "a study on how most studies are false" is taken as complete fact to peddle their worldview... Almost exactly how people take most other studies too as well, like the thing about eating chocolate everyday to be healthier... Hmmmm. Basically, like always, humans only hear what they want to hear

There are people who claim we have free will (not 'if free will exists, this is where it could originate from')... and then look at quantum physics ans heisenberg's uncertainty principle and say: see: there it is. This is an example of how people state a 'belief' and then make reality match up to their belief, dropping all doubt in the process. I guess seeding reasonable doubt on the scientific process also helps a certain 'agenda' forward.

So, does this mean that : a - Scientists claiming climate change is real are just jumping on the bandwagon to make money or afraid to oppose the prevalent view because it will impact their career. AND/OR b - Scientists claiming climate change is false are just pandering to lobbies for financial gain/going against the science to get attention.

"science" is far and away more reliable than any other way of knowing that we have." Deductive reasoning is more reliable.
Freak80MC Månad sedan
Isn't deductive reasoning what the ancient Greek philosophers used? And look how far that got them... Also you can't deductive reason at the scale of atoms because our logic breaks down, yet we know those scales to be true just to the fact that science has allowed us to engineer stuff that works at the microscopic level (like the transistors in the computers we are using to make these comments... in general science has created EVERYTHING that makes our modern world possible. So it must be pretty reliable...) It seems like most of the commenters didn't take this video to be "we need to reproduce studies to get more sure about things". It seems like they have taken the video to mean "if science doesn't support my worldview, it's unreliable. If it does, I'm gonna use that as evidence for my opinions"

I love this video, I've returned to it many times to refresh my memory on it. As invaluable a resource as this is, I can't help but want to push back on the one part of the video which was just a little too cute; the scientific method is not the most reliable way of knowing that we have. Indeed, it cannot be - we know some things with analytic incorrigibility, and others with existential indubitability, and still more with more mundane ways of knowing (and these, more often than any other, afford us the foundational assumptions on which any confidence in science itself must be based, for science is permeated with assumptions of this variety which fall strictly outside of its scope). What you should have said, I think, is that science is the most reliable method we have of forming beliefs about the natural world (in particular, natural nomological regularities). That isn't as cute, and it is a bit of a mouthful, but it has the advantage of not being false. What I would really like to see you explore, perhaps in the future, is whether some researchers approach science in such a way that they think P-hacking not merely expedient, but ethically imperative. If one is animated by a desire for the good more than for the true (perhaps especially if they are structural realists or constructive empiricists, or anti-realists of closely related varieties), and one regards science as a means to a promised land provided by a religious or political ideology (I'm thinking here especially, though not exclusively, of progressivism, critical theory, intersectionality, post-modern neo-Marxism, or any other name which is used for roughly the very same ideology), then it seems P-hacking your way to a conclusion in support of public policy positions you think morally imperative will be so highly motivated as to be inevitable, which may then, when unearthed, erode public confidence in science (as an institution more than as a method). For instance, consider Heather Douglas' argument in "Inductive Risk and Values in Science* " (you can find the PDF with a Scholar.Google search) and what that attitude might engender in the sciences if accepted by any significant fraction of practicing scientists.

I actually was unaware that 0.5 was sufficient. Are they not aware of standard deviations? I ran into this when I was doing research in to the NHS. It gave me a table of about 100 different results, which I then plotted into a chart for deviation from the norm. As expected the values fit well with a normal distribution, which meant that the few that were considered to be 'statistically significant' in isolation were merely artefacts of the larger sample size. So I had to report that while there were some deviations that none of them were considered to be statistically significant. For my research, I only considered results that were at least 1 standard deviation out from where they were expected to be. I did find some statistically significant results in other places that were not England. This make me very sad. :(
