Once, years ago, I got into a debate with somebody online who just kept dropping links to studies after making a statement as if it proved them correct.

One day, I got bored and decided to actually read every single study. The studies said nothing close to what the debater suggested and seriously opened my eyes to just how terrible some studies can be in terms of quality.

Now, I just assume that anybody who starts link bombing in a conversation has no idea what they're talking about and can't engage on a logical discussion.

Yep. This is why it makes me nearly physically ill when I hear people use terms like "science denier" or say things like "<insert political party here> don't believe in science" or "our laws should be based on science".

It is invariably some of the most scientifically illiterate, ideologically entrenched, and intellectually lukewarm people who spout this garbage as a retort to any sort of argument with which they do not wish to engage.

The tricky bit is there really are people who think that science is "just an opinion, man". See e.g. "teach the controversy" regarding evolution vs. creationism. There's certainly a place for "<X> don't believe in science" and "our laws should be based on science".

But the argument is so often misapplied that it's become meaningless.

I have argued against 5G deployment for example, not based on outlandish "zomg Bill Gates George Soros mindcontrol!!!11" or "brain tumours!!!11" nonsense, all of that is clearly nonsense. But the science is a lot less clear that there are zero effects than is sometimes made out to be, and there are also the ethical considerations of informed consent. I was, of course, immediately lobbed in with the crazies and called a science-denying conspiracy theorist, by someone with no expertise in the field who said I need to "listen to the science", in spite of my argument looking nothing like the anti-scientific nonsense from David Icke and the like.

Don't even get me started on COVID – any attempt to inject even the slightest sort of nuance was met with "you are literally murdering people with your unscientific nonsense!" and you were immediately lobbed in with COVID-denying anti-maskers or whatnot. At some point this stopped being a debate about trade-offs involving science and medicine on one hand and basic liberties and freedoms on the other and became some sort of moral crusade (and it seems it still is; there was a conference this month where masks at all times, full proof of vaccination, and a PCR test was still required, which seems a bit much for 2023).

A big issue is that any sort of nuance is often met with the most uncharitable interpretation because the genuinely crazy people have been getting so much attention.

The thing is, based on so many examples of people who cite “the science” that are clearly exaggerated or unsupported “just an opinion” isn’t too far off.

It shouldn’t be this way, but there’s a lot of undermining of trust in science because of this stuff.

Take evolution as an example. How many layers of scientific expertise have to be understood to really claim that you understand how evolution works? Archeology, biology, history, geology, genetics…potentially more?

At some point there’s a trust factor involved in accepting evolution.

Now apply that same realization with climate change.

The more complex, the more moving parts, the easier it is to find a part to be skeptical about and people will do exactly that. Especially if they are given reason to believe that the science is just there to support a political objective.

In the end, unless science can be easily replicated and demonstrated (gravity, boiling water, killing bacteria, generating power, flywheels, etc) it will boil down to trust for the vast majority of people.

Your last point is critical. People at the end of the 20th century had come to “trust the science” because it conferred tangible power on those who wielded it. “Science” could send a man to the moon or a bounce a phone call off a satellite to the other side of the world. Your average person doesn’t have to understand the rocket equation, or trust NASA. They can watch a launch in Florida and see with their own eyes the awesome power of “science.”

Then, folks started invoking the authority of “science” in connection with disciplines that don’t confer tangible power. For example, if “education science” worked, we would know it. It would convey power the results of which people could see with their own eyes without needed to pore through studies, or putting any faith in “education experts.”

I've come to the conclusion that science needs to be just another form of religion (without the theistic element). I don't have the time or the energy to go through the research to determine if climate change is real. I put my faith in the scientific process, which is probably the most successful thing we've ever come up with as a species. I'm not sure why I should believe some random dude, whoever he might be or what credentials he might have, on the radio/TV over the scientific community. Sure, they've gotten things wrong, but their success rate and their usefulness to our species is infinitely better than some politician being a climate change denialist just to appeal to voters. What process does he have and why should I trust it more than the scientific method?
I disagree with that attitude. I think most scientific information that comes to us through the media is reliable. If people stop trusting science (or they continue to stop trusting science), we are just left with superstition and religion. It was really hard for people to cope with the fact that during covid we started with the best explanations and then as we learned we improved on it and some ideas or expected safety practices changed. Good example is that many viruses spread through touch and covid spread through the air and that was a surprise.

People take that in and say I just don't trust anything. That is a problem with America because people stop believing in objective facts, saying that it goes against their beliefs. This is a major problem why America doesn't have enough engineers and scientists and mathematicians, because people haven't learned that your intuition can be wrong and you can overcome your strong expectation about something by studying something, debugging a program or whatever.

> I think most scientific information that comes to us through the media is reliable

Your general point is well taken but is severely and gravely undermined by the belief expressed in above.

It depends on how you define the “scientific community.” If your kid has a staph infection, there are people who make antibiotic creams that will make it disappear in days. They’re scientists. Their science gives them power you don’t have to “believe in,” because you can see the results.

Most people with a Ph.D. in a field with “science” in the name aren’t scientists. They work in fields that don’t have the same level of rigor as nuclear physics. (My degree is in aerospace engineering, and many real scientists would consider us bumpkins in how comparatively undisciplined our field is compared to their’s.) Those fields confer little to no power to produce tangible and undeniable results.

> Most people with a Ph.D. in a field with “science” in the name aren’t scientists

Computer Science. ;-)

Perhaps an appropriate assessment, given that CS seems to be half engineering/tinkering, half applied mathematics, and half nonsense.

Like how North Korea is a ‘democratic republic.’ If you have to put ‘science’ or ‘evidence based’ after your discipline, it’s probably not science (or science with lots of problems).

See: Social science Political science Evidence based naturopathy/chiro

You're right about this. And it makes discussion, much less "debate", so difficult. I'm pro-5G but willing to entertain the anti-5G evidence because what if there was some and it was true or at least unexplained?
One problem is that often science says nothing about policy.

_Science_ doesn’t say we should ban fossil fuels, but it does make predictions about what will happen if we continue to use them at the current rate.

It’s not science denial to be against the policy.

There's another important part of this though, oil companies pay scientific researchers to publish views against the veracity of climate change, research and predictions. That's why they say it's science denialism because those people are making shoddy arguments. Disagreeing about whether you care about global climate change is not science denialism but making up things to say there's no science is denialism.
That’s an important distinction, but is lost on 99% of the population.

Try to voice any skepticism about climate change policy and most people will call you a climate denier.

Same with vaccines; express a skepticism of efficacy and suddenly you are an anti-science anti-Vaxer.

The irony is that skepticism and asking annoying questions is essential to science. Ignoring ‘anti-scientific’ arguments is inherently anti-science.

yes certainly science can inform policy decisions. How do I put this...

Science has nothing to say about what we should set as the objectives of our policy. Science can, however, inform our approach to attaining that objective.

To oversimplify my view:

Politics = applied philosophy Science = applied epistemology

Pretending that science can create policy leads to things like eugenics (but Darwin said it would make us fitter so it must be ‘good’!)

My favorite term like that was “scientific consensus”. I used to point out that up until the 17th century the scientific consensus was that the Sun revolved around the Earth. I would get nothing but blank stares in response. It turns out that people who talk about “scientific consensus” typically don’t know whether the Earth revolves around the Sun, or vice-versa.
I'm staring blankly too. The idea is to forever invalidate consensus because people were wrong in the past?
Consensus means that people agree; it doesn’t mean that they are right.
Yeah, but it means they're far more likely to be correct. Iconoclast / Galileo gambit outliers are near nil.

We collectively know more about everything every year, science has generally given us a self-correcting living corpus.

The argument you're making is the same made by anti-intellectuals: don't trust institutional knowledge and consensus because it's been wrong in the past, look at mistake X. It's something like a systemic ad hominem.

They are not near nil. Every idea ever conceived has either been rejected or altered to match new observations.

That means that most ideas will end up being wrong in some way. The smoking-gun laws of nature are few and far between.

If you consider what % of ideas throughout history were plain wrong, it’s hard to believe that we have finally figured it all out and the consensus finally reflects reality most of the time.

> Yeah, but it means they're far more likely to be correct

I know what this means from a statistical perspective but I dont know what it means with regard to practical day to day decision making.

> The argument you're making is the same made by anti-intellectuals Isn't there some sort of fallacy that you are yourself deploying here?

It is especially frustrating when scientific ideas are applied to moral dilemmas. I see this from the far left wing frequently. The irony is that this same mindset is what led to the proliferation of eugenics apologists in the 1800s. The scientific consensus had absolutely no objections to eugenics on scientific grounds. In fact, "science" would seem to support it. Yet it is widely agreed that this practice is morally reprehensible nowadays, because humans were able to put aside their hubris and apply their moral reasoning.
Plenty of people realized that eugenics was unacceptable who were in the scientific world then, just like plenty of people understood that slavery was wrong. Which doesn't take away from the fact that plenty of terrible policies came out because leaders did have those views. I don't know what left wing ideas you've seen that are wrong, I'm sure that I've seen some left wing ideas that are wrong. I'm more worried about what do the leaders and the effective speakers in groups promote. Saying that I'm making you more free by taking away your choice of library books, or your choice about medical care, that's not an extreme view that only 1% of people have. It's pretty much the consensus leadership view of Republicans.
When reading the first draft of the California Math Framework, I followed many of the citations. My experience was similar to yours. In particular:

- some of the cited studies did not claim what the citation said they did

- some of the cited studies did claim what the citation said they did, but the experimental results were far too weak to support these claims

- some of the cited studies had such weak experimental design, that it would be hard to conclude anything about the subject at hand

This is one reason Wikipedia discourages using primary sources (i.e. individual studies) as references. Not that using secondary sources is perfect either, but you can "prove" almost anything by linking to studies as there are just so many of them. Do 1,000 studies on homeopathy and some of them will show a positive effect (even when done well, ignoring there are also many bad studies on these kind of topics).
> One day, I got bored and decided to actually read every single study.

Nothing is more entertaining than the meeting after a business presentation where someone fact checks the reference after the power point. When we have vendor presentations, we started doing this because... so many claims, so little truth.

Maybe assess the argument by the first two studies. If either of them do not support the point (or as has frequently happened for me, actually oppose the point) then you can reply for posterity and no one else needs to replicate your debunking effort.

“Your first two studies not only don’t support your argument but invalidate it, and I stopped reading after that.” ends most disagreements.

You will have probably done more work than the poster who often has just discovered keyword searches and related articles in google scholar or science direct, but everyone will learn something.

If you ever want to reject a study, just read it.

You will find something to nit pick.

I'm not saying you're wrong — I've got my name on exactly one paper so what would I know — but that being true would suggest that peer review is fundamentally broken.
No, it would suggest that every paper has something in it that can be considered a fatal flaw by a person biased against it. Peer review is precisely supposed to admit this and minimize flaws in conclusions given inevitable flaws in methodology.

Sort of a research paper equivalent of:

"If you give me six lines written by the hand of the most honest of men, I will find something in them which will hang him." by Cardinal Richelieu

Peer review is not a certificate of truthfulness, peer review just says that a grad student reading the paper did not found anything too suspicious there and it looks like a typical paper in that field.
Peer review, at its core, is a social consensus process. It can work, but it is structurally inclined to propagate agreement.

I wonder if it serves to reinforce this problem, as those more motivated to reinforce certain literatures or perspectives will surface those repeatedly in reviews.

There's a popular work that comes to this conclusion in its beginning chapters [0]. The basic premise is that the act of science and knowledge acquisition cyclically devolves into ideology and is then disrupted. Typically those who initially disrupt a scientific dogma are not treated well. Eventually the old guard literally dies off and the new ideas can begin to take hold.

[0] The Structure of Scientific Revolutions, T. Kuhn

> The basic premise is that the act of science and knowledge acquisition cyclically devolves into ideology and is then disrupted.

This can happen of course, but it's not really what Kuhn is talking about. Kuhnian paradigm shifts are to science what massive refactorings are to a codebase: the problem isn't that the old code was wrong (though it might also be wrong), it's that it can't be extended to meet new requirements. And while some of us are better at writing extensible code than others, no one gets it right every single time.

Not even that. I was a grad student that reviewed a paper submitted to a well-known journal from a heavyweight in my field. The paper's own data showed that the authors were reporting 95% noise. My advisor rejected the paper only to see it published a few months later (in another famous journal) after the authors removed the data that allowed us to detect the noise throughout the data.
A huge part of the problem is that the layperson is taught otherwise.
2nd grade we learned the scientific method. I don't remember peer reviewed being a thing.

Replication was critical.

Also, I've seen peer reviewed papers with atrocious stuff in them, unless I know the peer, it doesn't mean much to me. Give me 100 independent groups coming to the same conclusions. That has far more weight than a few of your friends/professors reading your paper.

I mean I think peer review kind of is fundamentally broken, but at the same time this phenomenon isn't necessarily a sign of it.

Even within technical papers, let alone pop writing or internet discussions, many of the claims citations are provided for are broad e.g. "X can increase people's anxiety". A very rigorous study might exist showing that when X happens a specific way it does increase some form of anxiety in some specific subset of the population, but using it as a citation for the broad statement without further context can be misleading at times.

It's in fact possible that by considering different subsets of the same statement you'd get an opposite directional effect. That can certainly be used to confuse people, especially in a situation where it is unlikely most readers will dive deeply into the cited works.

As far as nit picking - the same general principle applies. There will always be some tradeoff between scope, rigor, and available resources to do the study. If we waited for papers to be perfect in both correctness and interestingness/utility there would be almost nothing to ever publish.

So I think the systemic problem here is moreso an undervaluing of review article and text book type resources (both reading them and writing them) in favor of vomiting out random individual paper citations for whatever claim. Science needs more heterogeneity in the roles different PIs fill for the system.

Improving peer review process would be great (and might indirectly help), but I don't feel it's the root.

Not exactly. Control for that in a future experiment?

To be fair, as you start to leave chemistry, true knowledge(the goal of science) is impossible to find. The best we can get is little glimpses of the truth.

To be fair, I have seen studies that were pretty bullet proof. It just seems that most are lazy or simply impossible to prevent variables.

I'll often read through the studies in an argument but it is very unfeasible to keep up with these people because they can just keep throwing crap at you, and if you disagree with the study, they'll throw another at you until you give up. I remember reading through one 80 page paper on how a public option for healthcare would bankrupt us, but if you actually read through the thing, it never accounts for all the money saved by not being spent on private healthcare (which would fund the entire thing). My local power company had a similar situation where they posted a huge study explaining why solar was costing them a bunch of money, but if you actually read the study it explains that it considers lost income from solar as costing them money (in the same way that moving to a more efficient AC system would "cost" the power company money). It's all bullshit, and it's too easy to abuse studies to defend your position.
If someone replies within a few minutes with a link to a study, you can usually just assume it doesn't even support their point unless they're actually a researcher in the field.

It takes way longer even for experts to read and digest a paper thoroughly to evaluate the methodology and results.

Googling for 5 minutes and skimming the abstract for keywords that might be related to whatever you were arguing about is usually the norm online.

It takes years of training and feedback to learn to properly evaluate a paper in your own field, and that's after years of undergraduate education at least. Most people online skip even the basic textbook level background and think they understand what they're reading.

What are some examples of the claims people made vs what the research actually demonstrated?
mRNA vaccines are completely safe - Obviously false just like it is false for any vaccine since there are always going to be rare side effects in some members of the population. They very well may be just as safe as any other vaccine, but the truth is there are some things we won't know until a lot more time goes by. You can't say what the long term side effects are of something until it has been around for a long time.

Wind power is better for the environment - Similar to above, we don't really have data on the full lifecycle environmental costs of large scale wind farms. This is especially true because a good portion of the impact depends on how long the turbines last, what type of repair/recycle technologies are developed, and what type of policies get applied to recycling them. We see some things that look promising but others that are concerning.

Saying "mRNA vaccines are completely safe" is obviously not pedantically true. The same could be said of anything, not just mRNA vaccines. Nothing is ever absolutely 100 % safe.

It would, at least in theory, be better to realistically say what we knew and didn't know about the risks.

But public communication about those kinds of risks and tradeoffs is hard. If you say there might be any kind of a risk at all, some people are going to get hung up on that or grossly overestimate those risks compared to the benefits (or to the risks of not getting the vaccine -- also not something everyone would be affected by but clearly a non-zero risk).

Taking that into account, "completely safe" might be a better approximation than most other ones you could make.

While I understand what you are saying, I would disagree. Saying that something is completely safe when it isn't (as you say nothing is completely safe) makes it appear that people are being lied to when someone does have some type of reaction.

I think we are better of thinking of risk in terms of every day risk management. Comparing risks to things like driving 10 miles, getting hit by a meteor while sleeping, etc. can help create a better understanding of the risks.

I'm not sure I agree with it either. I'd personally much rather take a realistic estimate (in cases we have one anyway) than a simplified half-truth. But I think I can see a rationale for why some people doing the communicating may opt for the latter.

Comparing to something else that people might have a more realistic intuition of sounds like a good idea.

It is sort of like how when some people want to prove something is true they quote the Bible. I find the behavior especially strange when they are quoting the bible to prove the bible is true.
