> It remains a badge of honor for many who like to describe themselves as highly cultured or artistic to describe themselves as mathematically challenged, or to say that their brains aren’t wired for mathematics. Because many of those they hold in high esteem have made similar claims, there is no real social penalty to them for doing so.

For many scientific illiteracy is in the same category as mathematical illiteracy -- but the problem starts there already. Everybody should at least know what a Fourier transformation does -- it's not necessary to exercise it rigorously, but at least an idea... I think this video is enough to give even laymans an idea: https://www.youtube.com/watch?v=r6sGWTCMz2k

It's really not. We are going to pay very high price for this.
Indeed. It puzzles me why in our society numeracy doesn't seem to be as important as literacy. If kids struggle with learning to read we won't give up until they get it. If they struggle with fractions we often shrug and say their brains aren’t wired for mathematics. Sad.
As someone who isn't 'wired for math' (but still knows my fractions, so to speak) I can't imagine putting math up against literacy. Reading is so fundamental to both communication and learning. Why do you equate the two?
Math is pretty fundamental, it is the basis for a lot of what people do in modern society and provides a better basis for solving many problems than the alternatives.

Universal literacy is a relatively new concept that civilization went a very long time without. One can make the argument that it is not really necessary for communication or learning.

I don't really believe there is such a thing as not being 'wired for math' any more than there is such a thing as not being 'wired for reading'. Absent mental impairment it is something that can be learned, it's just that we generally do a terrible job of teaching it.

Stop. Danger. Caution. Poison. Love. Hate. Trump. These things and more are communicated perfectly well without multiplying by a power of ten or knowing what that power of ten is called.

As a species we seem to be terrible at things like estimation, probability, and at risk assessment. That's often wrapped up in this innumeracy business, too.

Is that a reflection of the fact that it's far worse to be illiterate than innumerate? Sure, an innumerate person will struggle in all kinds of everyday contexts and probably won't end up working as an engineer or mathematician. But if they can read and write fluently, and are skilled/talented in ways that don't require much math, they can still excel in a number of career types.

By contrast, if a person can't read or write, they're shut out of a huge fraction of careers, even if they're exceptionally good with numbers.

Because its not so important to survival.

You will derive more pleasure in your life knowing how to pickup chicks (or guys), or caring to your family, than having any pain thinking the earth is flat. No pain at all. Ignorance is bliss.

Science is interesting but interesting does not make it fundamental for you as an animal.

Specific illiteracy is positively omnipresent.

Try talking to an accountant about Renaissance art. Try talking to a butcher about linguistic theory. To a neurosurgeon about Egyptian architecture.

Specialisation is what our society mandates, and you don’t improve your lot by having knowledge which is extraneous to your specialisation - unless you have a lot of extraneous knowledge, in which case, congratulations, you’re an undesirable generalist.

We live in a world built with the scientific method, however, which means that scientific illiteracy has greater scope for making poorly informed impactful decisions. Likely nobody will die if you don’t know a finial from a pilaster.

So - rather than viewing this as a problem of scientific illiteracy, I view this as a problem of overspecialisation. We are taught, from early on, to focus on that which interests us, and to hone in on a tiny slice of information to pursue a specialised career.

Crack that, make being a generalist desirable, and you have your scientific literacy - but doing so is incompatible with our current economies.

But having niche knowledge of art, architecture and linguistics is much different than than understanding the scientific method, basic statistics, how to interpret studies and critical thinking.

Those fundamental skills are essential to making informed decisions

you're just proving his point.

knowing much about linguistics teaches you much about culture and/or the human cognition. knowing much about arts (including things like literature, music, etc.) teaches you things about the human condition, about history, about philosophy, ...

I see those as equally fundamental as scientific knowledge.

> To a neurosurgeon about Egyptian architecture.

See Ben Carson.

Quilette is an interesting choice of publication, given that they don't mind promoting one particular kind of "scientific" literacy:

What's scientifically illiterate about this?
My apologies. I didn't know that Skull Calipers Monthly was such a popular periodical on HN!
From the 2nd article:

Before proceeding, we should be clear about what we are not saying. First, we are not denying that research into the genetics of human differences has been misused for appalling purposes at various points over the last two centuries. Second, we are not denying that some of the scientists who have undertaken such research were motivated by racial animus or by a desire to subjugate other people. Hence we understand the temptation to assume the worst about anyone who might be willing to entertain what we have called ‘hereditarian claims.’ Nonetheless, equating hereditarian claims with racism is a fallacy, and one that we believe is likely to end up doing more harm than good.

The thesis is basically "yes, humans do in fact differ physiologically, in groups corresponding to geography, and no it is not inherently racist to assert this."

There's definitely a segment of HN trying to push these kind of dog whistles. Quilette is an outlet of the alt-right. No reputable publication does race science.
Math is much more binary. I can describe a problem quite well, and describe it well enough that I could be said to understand it. But I really can't put many problems into math. I've seen others do it, and it seems like a wonder to me. I'm not a dumb guy either, but my english and math scores on my SAT were off by more than 130 points. Some people in this thread are claiming that it's foolish to think that some people don't have math brains. I'm not sure what to tell you -- you're simply wrong. Could I understand math better than I do? Almost certainly, but it's unlikely I could ever be an engineer.
You are correct and those people are too ignorant to understand how ignorant they are. Don't worry about the noise they generate. They have nothing else to contribute.

Here is Hermann von Helmotz on Michael Faraday (who knew no math) -

"Now that the mathematical interpretation of Faraday's conceptions regarding the nature of electric and magnetic forces has been given by Clerk Maxwell, we see how great a degree of exactness and precision was really hidden behind the words which to Faraday's contemporaries appeared either vague or obscure; and it is in the highest degree astonishing to see what a large number of general theorems, the methodical deduction of which requires the highest powers of mathematical analysis, he found by a kind of intuition, with the security of instinct, without the help of a single mathematical formula."

There's a difference between "it's unlikely I could ever be an engineer" and "I can't pass Algebra 1".

High level math and things like number theory do require a certain creative intuition that is harder for some people to learn than others, but if you can follow a recipe, figure out who has the right of way at a stop sign, or follow the rules while playing a card or board game, then you can get through Calc I.

I used to work as a math tutor when I was in College, and tons of the students who would come into the tutoring center seemed to have a sort of math-phobia. They'd been saying that they just "aren't good at math" for so long that they couldn't bring themselves to try. If you could convince them that they could do what you were asking them to do, it was pretty straight forward to walk them through the math itself.

My wife is a special education teacher now, and experiences the same phenomenon. She has students who really do struggle, but for a lot of them, it's just a matter of convincing them to actually look at the problem and the tools/patterns they have been taught.

Is is incredibly destructive when people (including teachers) present math as some sort of black magic that they won't touch with ten foot pole. There are a lot of students out there for whom math isn't necessarily immediately intuitive, or who simply had a rough school year at the wrong time and fell behind. When those students hear others dismiss mathematics it validates them doing the same, and the next generation looses one more potential scientist.

As you may have noticed, this is an issue close to my heart.

/end rant

I think you make a good point. From my standpoint, I could pass algebra for sure. (I actually did really well in my college-level statistics course!) But what I can't do is take a real-world problem, and turn it into an algebra equation. I understand the math fine, but I can't "visualize" how it aligns to things in the real world.

In this way, a word problem on a test because a matching game: because they phrase the problem in a certain way, and I know we covered X problem recently, I know the following equation must fit into the words. Without the guardrails of the test, this whole process falls apart completely.

Some of the most scientifically illiterate people I've encountered are the people who say things like, "We listen to the science when it comes to COVID-19". Let us be perfectly real. When it comes to political decisions based on forecasts, you are not "listening to science".

Science can answer many questions. I can ask it, "How long do I need to fire the engines to achieve this particular orbit", or perhaps "How much material do I need in this region of the bridge to sustain the load of traffic going across it?"

But science is not the computer from Star Trek. I can't come to science and ask it, "How long should we quarantine to minimize health impact, and maximize economic recovery?" Ultimately, that question does not have a scientific answer. It can be informed by statistics -- to the best that we understand the numbers, and scientists can present models of what they think the future will look like... but results not guaranteed.

Some problems have clear cut answers, that science can contribute concrete solutions to. Other problems do not have clear cut answers -- but have a large population of supporters claiming that all "the science" agrees with them, and to disagree with them is to shun reason.

This is also scientific illiteracy.

Edit: see replies below this post which clarify what was intended. My response was based on a misunderstanding; that cleared up, I now agree with the poster.

> When it comes to political decisions based on forecasts, you are not "listening to science".

if those forecasts are based on science/maths, yes you are listening to science.

> Ultimately, that question does not have a scientific answer

yes it does, just the best science can do (as in, estimate) based on limited data. If you want better than that, drop to your knees and ask god because that's all that's left.

Your post badly misunderstands what science is.

I think you are misrepresenting the parent which explicitly mentions tradeoffs. Science can help inform those tradeoffs but cannot make them for you. At the risk of reopening a rather heated discussion from yesterday, "science" cannot answer the question of whether it is reasonable to have a policy allowing outdoor dining in, say, NYC.

ADDED: Science can (probably and imperfectly) help you estimate how risky a given behavior is likely to be. However, it cannot tell you whether, say, a presumably low risk activity (both personally and in terms of disease spread) should be allowed given economic impact, people's social needs/wants, etc.

This is perfectly what I wanted to say, but was incapable of saying. Thank you.
What science can do is provide estimates with error bounds. Sometimes the error bounds are extremely large during a developing situation, and people should absolutely be aware of that. There's a major discussion to be had about risk/reward tradeoffs in the face of high uncertainty. (E.g., the relative cost of mandating face coverings is pretty low, even if the science is temporarily uncertain.)

However it becomes impossible to have such discussions when a large contingent of the population are ignoring all of the scientific data, and instead basing their opinions on motivated reasoning, faith, or political preferences.

I don't disagree with any of that. Indeed, there are many policies and behaviors that probably fall into the "better safe than sorry" category--given how much noise and uncertainty there is in the data--although even possibly reasonable people will vehemently disagree about what precise policies/behaviors that applies to. (As you see from voting patterns and discussions here.) And, yes, I also agree that face coverings under at least many circumstances fall into that category.

At the same time, there are different tradeoffs because different people (and governments) are approaching risks and rewards differently even if the facts were known with high certainty.

For what it's worth, "science" in many fields is inherently statistical. Statistical illiteracy is arguably more pervasive and insidious than "scientific" illiteracy.
I understand what you're saying, but I think there's some "both sides"-ism at play here.

Yes, there is a level of scientific ignorance displayed when people hand wave and claim "the science" is on their side without actually understanding the science. However, there is a huge qualitative difference here, illustrated even by your example of quarantine recommendations.

If we approximate an answer to "What is the optimal quarantine strategy?" through the combined efforts of various sciences--statistics, biology, etc--then while the results are not guaranteed, the recommendation is certainly not unfounded. It may be incomplete, but it is built off of decades of empirical evidence.

Conversely, outright ignoring recommendations about COVID or climate or something similar, simply because "science isn't always right" or because you "aren't a scientist" is a different thing altogether.

> outright ignoring recommendations

Have you ever wondered why it's not terribly controversial to "recommend" seat belts and airbags?

But when your "recommendation" is to join a large organization and funnel millions of dollars into it, or to levy massive taxes to prevent "the end of the world as we know it"? Pardon me, but I'm deeply skeptical.

Do you remember Solyndra? $500 million loan from the government. Went bankrupt.

I will not accept this straw man re-framing of the issue. Yes, "some people" say "but science isn't always right", and that is a poor argument indeed. But I am not.

>why it's not terribly controversial to "recommend" seat belts

Yet this was not always the case. Growing up wearing seatbelts was the exception, not the norm. Much less the law in some places.

Yes, and I remember having discussions on whether airbags caused more injuries than they prevented! But the fact of the matter is the issue is largely settled in the public eye. How did we get here? The answer is simple. The approach was a dispassionate search for the best solution.

There were no "scientists" claiming hyperbolic doomsday scenarios if we didn't pass specific legislation by a certain date. The collapse of our transportation infrastructure due to Kessler Syndrome -- but for highways. This should cause any rational person to be skeptical.

There were no fund raising rallies held by highly influential "scientists" who refused to wear seat belts themselves. This too, should cause any rational person to be skeptical.

People did not start with a chosen solution, and selected evidence to back it. They started with evidence, and searched for the best solution.

In effect? Seatbelts and airbags weren't a cargo cult driven by celebrity "scientists" that relied on emotional appeal. If you want your politicians to "listen" to "science", then you must divest the emotions, the desire for power, and the appeal to authority from it.

I assume it was a combination of incremental laws and public safety campaigns. It's also true that, in the US and I assume many other countries, there's been a general and incremental shift towards safer behaviors and products of which airbags and seatbelts are just two examples. Increasing automobile safety even at increased cost, etc. wasn't exactly swimming against the tide.
When seatbelts were introduced, there was indeed a number of people opposed to it and just like with COVID19, claiming it infringed on their rights and refusing to wear seatbelts out of spite.

The reason it's not controversial nowadays is because it's (almost) universally accepted as a good idea (though people do buy fake seatbelt plugs to disable the alarms)

> I understand what you're saying, but I think there's some "both sides"-ism at play here.

Why do these conversations "always" go like this, even on a site as rational as HN? If we can't even discuss these very real issues here without rhetoric, how do we expect politicians and the masses (and here I include literal deniers) to do so? Because that is what we are asking of them, is it not? To stop being stupid (which they are doing, to a very large degree), and to start being rational?

Also: why is an article as reasonable as this [flagged] (and therefore removed from the public discourse here)? We ask others to stop living in an information bubble, yet are we willing to do so ourselves?

Might this flagging (of which this is but one of who knows how many instances - HN users shall not know such things) hint at some underlying human characteristic that is a root cause of why we cannot have nice things? Obviously speculative, but it seems reasonable to me.

> even on a site as rational as HN?

This site is made up of people, just like all the other sites out there. As a group, HN is no more or less susceptible to biases and irrationality than any other group of people or any other website. Our starting lemma should be that we are flawed, not that we are inherently less flawed. Acknowledging our biases and irrationalities is the first step toward overcoming them.

> This site is made up of people, just like all the other sites out there. As a group, HN is no more or less susceptible to biases and irrationality than any other group of people or any other website.

From a binary perspective, agreed. From this non-comprehensive perspective, you are correct.

But the reality here is more complex than a binary.

From a continuum perspective, is it actually correct that HN is "just like all the other sites out there", that they are "no more or less susceptible to biases and irrationality than any other group of people or any other website"?

This level of precise consistency across any arbitrary grouping of people seems rather unlikely to occur in reality, and if it was like this, you'd think someone would have noticed it. Also, this take on it seems rather contrary to my "feel" for the aggregate self-evaluation that the individuals members of this community have voiced. I'm fine with either one, but perhaps it might be useful for us to decide on which it is.

If you think about it, if superior rationality is literally impossible, then are we not completely wasting our time on discussing where flaws exist in society, and which groups need to be focused on and improved (which is a very common topic of conversation around here)? If nothing can be done, why do we not just abandon the entire topic of improving the world and devote the remainder of our short lives to enjoying ourselves?

Conversely, outright ignoring recommendations about COVID or climate or something similar, simply because "science isn't always right" or because you "aren't a scientist" is a different thing altogether.

Isn't that a strawman though? How many people actually give an answer like "science isn't always right" when choosing to ignore recommendations about COVID? Perhaps it's the circles I move in, but most people who think COVID recommendations are junk (which doesn't mean they don't follow them) can give far more reasoned and deep explanations for their views than the people they disagree with. Absolutely standard to get an answer like "because I trust the experts" (i.e. "I have no idea") from people who are the most passionately in favour of masks, lockdowns etc. You don't see that in reverse, because people disagreeing with authority by definition can't make an appeal to authority.

This is not my experience at all.

I've seen many people opposing masks and lockdowns due to dangerous half-knowledge and appealing to "that one doctor is also saying that the recommendations are junk (but they are shunned by the mainstream press)".

Of course, we usually find our own reasoning valid and logical and tend to think that the other side can't give "reasoned and deep explanations". I can't claim to be unbiased here.

I'll just note that, from a Bayesian perspective, "trusting experts" is usually not the worst idea and something we're basically forced to do every day anyway. I listen to quite a lot of what some of the experts way, but of course, I am completely unable to independently verify that what they say is valid - without decades of experience in the field, this is simply impossible.

I think they're just using a different definition of "expert" to you. Your reply alludes to this; your definition of an expert involves whether journalists say they're experts. How would journalists know?

Trusting experts is definitely a good policy from a Bayesian perspective given the dictionary definition of expert, i.e. "a person who is very knowledgeable about or skilful in a particular area" to quote Google's top result for the definition.

The problem we have with COVID is the people journalists present to us as experts (invariably academics) keep saying incredibly dumb stuff that's totally wrong, and by now many of us have concluded these "experts" don't actually know any more about disease than the man on the street does.

This is an inevitable problem with how academia is structured. Academics aren't financially rewarded for being correct, like private sector experts are. They're rewarded for writing things their peers find interesting. That's a totally different thing. We hope that being interesting and being correct are strongly correlated, but the replication crisis and general low standards observable in research papers are strong evidence they actually aren't.

I am completely unable to independently verify that what they say is valid - without decades of experience in the field, this is simply impossible.

The people you're disagreeing with also disagree about this. I've read a lot of epidemiology papers this year. The field is a joke: epidemiology is a piece of piss. The Gender Studies of medicine. It's just stats and some basic programming. I've not once had to look up any biology when reading these papers (microbiology being a genuinely hard field) because none of them use any. It's absolutely straightforward to find major, severe defects in these papers without decades of experience in this field. There's definitely a huge gulf in how difficult and deep different fields are, certainly, not all scientific endeavours are the same.

> The problem we have with COVID is the people journalists present to us as experts (invariably academics) keep saying incredibly dumb stuff that's totally wrong, and by now many of us have concluded these "experts" don't actually know any more about disease than the man on the street does.

It's not "what journalists say". Those people usually have valid credentials, e.g. when they are the people that developed the first PCR test for the new Coronavirus. I trust such people much more than random people on the street (or on the internet).

> The people you're disagreeing with also disagree about this. I've read a lot of epidemiology papers this year.

Forgive me if I don't find it terribly convincing that someone over the internet is trying to sell me something like this. Many fields of study are really hard to understand without a lot of context. There might be implicit things you might not be aware of. The internet is full of people who think they have found "flaws" in mathematical proofs or have discovered why FLT is true.

But you're also claiming that all the "experts" and all the relevant papers are from epidemiology whereas we also have a lot of contributions from other fields, such as virology or vaccinology.

I don't think virologists have contributed much so far, at least not to government policy. That's driven almost entirely by modellers.

I'm not asking you to blindly trust me on this. By no means. Go read some of the papers yourself if you like. The value of academic credentials in the field of epidemiology is zero. These people just constantly make basic errors in their papers and standards are so systematically low across the board nobody notices or cares.

I've posted here a list of just some of the problems I've noticed whilst reading these papers:

https://news.ycombinator.com/item?id=25202182

By all means, have blind faith in the credentialed classes. Just remember these are the same people who came up with critical race theory, every replication failure in the field of psychology, the decades of 180 degree turns in nutrition, etc. This article is a good (albeit slightly technical) introduction to some of the problems outsiders find when they sit down and actually read academic output:

https://fantasticanachronism.com/2020/09/11/whats-wrong-with...

It's useful because it has some meta-scientific analysis of quality problems in scientific papers.

Virologists have been instrumental in the debates relating to hygiene rules, the role that aerosols play for the infection, the different tests that exist and when/how they should be applied, what mutations mean or don't mean for infectiousness and immunity, and they can at least partially speak to why certain hypotheses that were observed empirically are not implausible from a biological point of view, or to how vaccines fundamentally work. They're also often in regular contact with practitioners on the field and can speak to the situation there, probably more so than random people on the street.

Here in Germany, virologists have very much been at the center of media attention (and not only of the media: the first PCR test for covid-19 was co-developed by Prof. Drosten who leads the virology department of the Charité clinic in Berlin).

> By all means, have blind faith in the credentialed classes. Just remember these are the same people who came up with critical race theory, every replication failure in the field of psychology, the decades of 180 degree turns in nutrition, etc.

As well as with countless examples of genuine scientific and technological progress. It's not that credentialed scientists are always right, it's that the scientific community (not so much individuals) is much more likely to be right than random people. And that doesn't mean that publication bias isn't a thing, but I'm not gonna hedge my bets on what some un-credentialed people are going to say because they looked at a bunch of papers.

edit: and I'll also mention that it seems you imply that scientists are a uniform bloc or that they all propose the same measures but that's not even true. But they do, largely, agree on some key issues, most notably, that this is a dangerous virus. It is my understanding that not even Tegnell (from Sweden) denies this.

At least in the English speaking media I hardly ever see virologists mentioned. However, maybe I should read some of their papers too then because basically all the advice around masks, lockdowns and so on has been proven wrong by observational data. Totally unclear why; perhaps there's some basic issue with germ theory. It seems unlikely but there aren't that many possible explanations. However these policies (the "non pharmaceutical interventions") have in the Anglosphere all been proposed by epidemiologists, not virologists.

Oh, the Drosten PCR test is under fresh fire today by a team in Denmark for having design issues, and of course we may observe the claim that PCR testing has no false positives must have come from either microbiology or virology (not that there's much difference).

the scientific community (not so much individuals) is much more likely to be right than random people

It's clear now that this isn't the case at all. The successes of physics and chemistry tell us nothing about fields like social psychology because the norms and practices within those fields are totally different. There is no "scientific community". Wildly different thresholds for statistical significance are one such difference that hits you immediately when comparing fields, but the issues are far deeper and more complex than just that.

Epidemiology is a pseudo-science. I've read so many papers by now that are just ludicrous and would never be accepted (I hope!) in more rigorous fields, that you can't really convince me by making vague allusions to the awesome powers of SCIENCE! Epidemiologists aren't wrong as random individuals, they are wrong as a bloc, as a set of institutions, as an entire field. That's exactly why peer review doesn't help: the papers are reviewed by peers who have standards just as low as the people they're reviewing. And unfortunately in academia, peer review is the only tool they have to catch problems.

But they do, largely, agree on some key issues, most notably, that this is a dangerous virus. It is my understanding that not even Tegnell (from Sweden) denies this.

That's a vague and unscientific statement, so sure, of course epidemiologists make it. "Dangerous" is entirely relative. Dangerous compared to what? Statistically it's about as bad as a bad flu wave, which is the sort of event that's been seen many times in the living memory of even quite young people. Most people wouldn't say that's dangerous, even though in some senses almost anything can be dangerous to some people. After all, lots of people die from drowning. Is water dangerous? In some contexts, sure. In others, no.

> "How much material do I need in this region of the bridge to sustain the load of traffic going across it?"

To nitpick a bit: anyone who answers that question for a living will be practicing engineering, not science. Just as an excellent physician can espouse wildly unscientific beliefs, so too can someone become quite good at the craft of engineering without actually doing much science at all.

> I can't come to science and ask it, "How long should we quarantine to minimize health impact, and maximize economic recovery?" Ultimately, that question does not have a scientific answer. It can be informed by statistics -- to the best that we understand the numbers, and scientists can present models of what they think the future will look like... but results not guaranteed.

Correct me if I'm wrong, but you consider "hard" disciplines like orbital mechanics and structural engineering to be science, and anything with less certainty in it to be not science, but statistics. This is inaccurate. Find me a scientific field that doesn't involve uncertainty and statistical analysis. Your examples of orbital mechanics and structural engineering certainly do. Conclusions made in both of these disciplines will always need to account for various sources of irreducible error (e.g., uncertainty in mass, temperature, altitude, fuel load; simplifying assumptions about atmosphere structure, gravity anomaly, solar wind, etc.). The importance of safety factors is the ultimate proof that uncertainty is core to engineering: https://en.wikipedia.org/wiki/Factor_of_safety

Science is the modeling of reality by formulating and testing hypotheses through observation and/or experiment. Does epidemiology not fall squarely within this definition? What do you propose as an alternative approach to inform governments and individuals what to do in the face of a natural phenomenon (a pandemic) which, although inherently uncertain, exhibits behaviors that are decidedly not random and inherently unpredictable?

Statistics by definition is not science. The vernacular usage of science refers to the empirical sciences; physics, chemistry, geography, biology. Mathematics, statistics, and computer science are all formal sciences, sometimes simply referred to as math.

See the application section of https://www.cdc.gov/csels/dsepd/ss1978/lesson1/section1.html.

And for when the two fields clash: https://www.nature.com/articles/s41467-018-04243-3

1. Good luck doing science without at least basic statistics. Have fun trying to combine your experimental results without using some notion of averages, pooled uncertainties, etc.

2. My original point was that the presence of uncertainty and the need for statistical analysis does not magically mean that whatever you're doing isn't scientific.

> To nitpick a bit: anyone who answers that question for a living will be practicing engineering, not science. Just as an excellent physician can espouse wildly unscientific beliefs, so too can someone become quite good at the craft of engineering without actually doing much science at all.

Engineering is based on science. They aren't scientists but what they do is based on science.

Science is the modeling of reality by formulating and testing hypotheses through observation and/or experiment. Does epidemiology not fall squarely within this definition?

This is really the heart of the issue, in 2020 at least (I hope people will go back to arguing about climatology soon!). In theory epidemiology does fall squarely within that definition. In practice if you read their papers you'll quickly discover most of them are entirely pseudo-scientific. I've read a lot of them this year. Here are some things that are absolutely standard in computational epidemiology (modelling) papers:

• Making predictions without writing a follow-up paper to study how closely observed data matched. Epidemiology routinely makes predictions that are wildly different to reality. This has no impact on the field at all. Science is meant to involve adjusting hypotheses if predictions don't match collected observational data, but in epidemiology step 1 is make a prediction with a model. Step 2, goto step 1.

• Making unfalsifiable predictions.

• Ignoring data that falsifies predictions.

• Altering predictions post-publication via public statements.

• Truncating graphs to hide data that would invalidate an argument.

• Using long since obsolete data, or data that aren't the best available when the paper is written. Invariably this makes the predicted epidemic worse, I've not yet seen anyone do this where it leads to better outcomes.

• Giving confidence intervals so wide they are equivalent to saying "we don't know what will happen" whilst not making that obvious.

• Incorporating model parameters that are simply made up, not based on any observational data.

• Engaging in circular reasoning.

• Ignoring basic biology. One of the most surprising things about epidemiological models is that they basically don't utilise any biology at all and epidemiologists will happily violate basic biological or historical common sense if it helps them achieve their goals. For example they calculate R0 using case curves. R0 is meant to be an intrinsic property of a virus representing how infectious it is, but one model I saw calculated a totally different value for COVID for each outbreak/country it was applied to. Clearly their values for R0 couldn't be correct, as it's the same virus everywhere so the values should be at least a little bit consistent. They were orders of magnitude different! This didn't bother anyone in the modelling team or anyone who peer reviewed their work at all. Another paper assumed Rt (case curve rate of change) could only change if government interventions forced it to, which flatly contradicts tens of thousands of years of experience in which epidemics rise and fall naturally, without lockdowns or masks of any kind. No peer reviewer quibbled with this, one even said it was a reasonable assumption.

I could go on all day. Maybe one day I'll write this up somewhere outside HN. But seriously, epidemiology is by far the most problematic field of "science" I've ever seen, and I read plenty of research papers from other fields. I don't consider what they're doing to be even slightly scientific: way too many papers are flat out intellectually fraudulent.

Your experience and comment history during the Covid-19 crisis merits authoring a book possibly? You have, over time, contributed much insight but this forum is not the best one for an excellent writer.
Thanks! I'm not sure why your post was dead but seeing as you're so nice to me, I vouched for it to bring it back.
As Asimov once said: "It is not so much that I have confidence in scientists being right, but that I have so much in nonscientists being wrong." Right now there are people running around saying that COVID is as deadly as the flu, that the pandemic was faked, that masks are a conspiracy. You don't have to believe that epidemiologists are 100% correct about every recommendation during a fast-developing emergency in order to see how the rejection of evidence and conspiracy-theorizing are harmful.

Which is the current best estimation of the risk of getting covid-19 and dying?

Which is the current best estimation of the risk of getting flu and dying?

I actually would have guessed they were pretty close. Apparently I was wrong:

The following claims 5% vs .2%

https://www.businessinsider.com/coronavirus-death-rate-us-co...

Then again this chart seems to indicate something closer to 2% of confirmed cases are fatal for Covid:

https://ourworldindata.org/grapher/total-deaths-and-cases-co...

I imagine more non-fatal Covid cases go unreported than fatal ones so perhaps even that's high, but it's still close to an order of magnitude worse than the flu.

Edit:

That first source isn't great, and is outdated anyways. This one seems to verify the ~2% for Covid in the US.

> Right now there are people running around saying that COVID is as deadly as the flu

COVID is as deadly as flu. Some people just underestimate flu, as if it's something not dangerous.

> that the pandemic was faked

Technically all pandemics are faked, because what is and isn't pandemic is more or less an arbitrary decision made by some official purely for propaganda and obedience reasons. It doesn't actually matter if it's called pandemic or not.

> how the rejection of evidence and conspiracy-theorizing are harmful

Evidence based reasoning is not much different from superstition, it could be just as harmful as rejecting evidence to whatever you think rejecting evidence is harmful. To illustrate how faulty that reasoning is, here you are rejecting evidence that there was a literal conspiracy against general population with some officials and institutions telling people that masks don't work, an evidence they are liars, but somehow you don't want to consider that evidence in your evidence-based reasoning and suggest that others should not reject evidence from liars.

Of course you can't just accept evidence if you want something more than a superstition level decision making. For that you need to actually think and calculate, with all those base rates and probabilities, use something like bayesian reasoning or whatever, do some science. Even just quickly estimating this is still better than "accepting evidence".

I think that you are building strawman of what "listening to scientists" in the context of covid is like and then kill that strawman, basically.

Listening to scientists in the context covid will not tell you exactly how long quarantine should be. But it gives you multiple predictions you can start with and then over time see which are more correct and which are less correct.

It does also answer some of quite sure responses to questions that actually ended up disputed. Like: does the Covid have ability to overrun healthcare system? Do asymptomatic spread exists? Is the Covid just a little flu?

>"How long should we quarantine to minimize health impact, and maximize economic recovery?"

You're not asking a scientific question, you're asking a political one, because you also want the economy to do well, which is political.

There are two conflicting questions there, in reality; "How long can we quarantine without affecting the economy?" (Answer is like 0 days)

And "How long must we quarantine to eradicate the virus?" (Answer is around 140 days if a single quarantine unit contains up to 10 people and they infect eachother on the last day of symptom-freeness).

Because the question is not only political but considers two conflicting requirements, you can either satisfy both in a bad way or satisfy one well and abandon the other.

A similar situation occurs when you are tasked with optimizing the material usage for a product. Science can tell you how little product material you need so that it performs to spec and it can tell you how much you need so that it'll perform it's function as long as possible. The balance informs the price of the product but politically capitalism wants you to prefer a low price, similar to how capitalism will prefer no quarantine and lockdown.

Apparently on HN, you're not allowed to admit there are tradeoffs in the current situation especially to do things that some consider to be unnecessary.
You can have tradeoffs but then you're no longer answering scientific questions but either a political question or a question of personal belief (ie, "which you think is better").
Of course. Science can help you e.g. estimate risk. But balancing that risk against other factors has to be a political and/or personal tradeoff. There's no way it could be otherwise. Science, even if it could provide perfect information, doesn't have the tools to make policy decisions. Whether schools should be wide-open, hybrid, or remote only is not a scientific decision although, of course, whatever scientific data is known or thought to be known should of course factor into any decision.
That is exactly the point but also somewhat auxiliary; when people say things like "science can't answer these questions" the issue is either that the question is already politically loaded or requires a tradeoff between two opposing goals, where this balance is policy not science. Science can't solve all our problems but at the same time, it doesn't mean we should discount science when trying to solve them.

When I ask people to listen to science, that doesn't mean "have science solve the problem entirely" but "all viable solution maxima are scientifically solvable, the tradeoff is ethical". If someone suggests a solution that is not scientifically solvable, then it ought to be disregarded or considered for what is it is; pure politics, something you have to think about morally and ethically.

> Some of the most scientifically illiterate people I've encountered are the people who say things like, "We listen to the science when it comes to COVID-19". Let us be perfectly real. When it comes to political decisions based on forecasts, you are not "listening to science".

This feels like a straw man to me.

First, let's be very clear: There is absolutely a cohort of people out there who are objectively denying the scientific reality of covid. Those denials ranges from the absurd (e.g. covid doesn't exist, it's a conspiracy, it's going away), to the distorted (e.g. covid is no worse than the flu), to the simply wrong (e.g. masks don't protect you, they actually make you sick).

I think the refrain "we listen to the science when it comes to COVID-19" is short hand for distinguishing oneself from folks in the groups above.

Let's also be clear that statistics and modelling are scientific methods. I'm frankly a little baffled that you've attempted to draw a line between these two things. Science can absolutely help you assess questions like "How long should we quarantine to minimize health impact, and maximize economic recovery?" Will the answers be probabilistic? Yes, absolutely. That doesn't make them any less scientific, and to suggest they are suggests its own form of "scientific illiteracy".

Further, "the science" is very clear: lockdowns are effective, masks help, social distancing helps, contact tracing helps, and so on. "The science" is also clear that none of these are quick fixes or panaceas. They're all part of a web of interventions that each provide some small measure of protection that, taken together, can help keep the pandemic under control. This is the "Swiss cheese" metaphor in action.

Science can also be used to assess the effectiveness of these methods versus their tradeoffs by, again, employing statistical approaches. Are those methods foolproof? No. But they're far from guesswork. I'd argue it's this basic misunderstanding that leads people to, for example, dismiss climate modelling...

Now, ultimately, the decision as to what to do is a political one, not because statistical models and methods are flawed or inaccurate, but rather because there's always going to be a range of trade-offs, and the trade-offs we make are ultimately a political decision.

But the least we can do is expect our politicians--not to mention the people around us--to assess those trade-offs based on rigorous facts and statistical methods. That's what "listening to science" means.

> Further, "the science" is very clear: lockdowns are effective, masks help, social distancing helps, contact tracing helps, and so on.

Of your list of things, masks and lockdowns aren't very clear - they don't seem to be helping given the resurgence this fall. Lockdowns might even have made it worse, pushing people indoors where it spreads easier and there's less sunlight, instead of encouraging social distancing in wide-open outdoor areas.

If anything, it seems COVID-19 is seasonal, and introduction of lockdowns and masks in the spring just coincided with when it was waning anyway.

(comment deleted)
As an addendum. Many people (quite frankly) worship "Science" like it is a benevolent deity. You just have to "listen" to it, and good results will come out, bettering society.

But terrible things happen when you try to apply science to a field that it should not apply to. Science can tell you how to do something effectively. It will not tell you whether or not it is good or beneficial to do a certain thing.

There was a news article recently published, that claimed that Iceland had eradicated Down's Syndrome. The mother runs through a battery of tests to determine if her baby has a genetic abnormality -- and if so, can choose an abortion. Unequivocally, this is genocide! Genocide!

Contrary to the "IFL Science" types who wake up singing "There's a great, big, beautiful tomorrow", Huxley has an appreciation for what science is truly capable of.

> We are living now, not in the delicious intoxication induced by the early successes of science, but in a rather grisly morning-after, when it has become apparent that what triumphant science has done hitherto is to improve the means for achieving unimproved or actually deteriorated ends.

> The mother runs through a battery of tests to determine if her baby has a genetic abnormality -- and if so, can choose an abortion.

Providing expectant parents with better information and more choice? Sign me up.

> Unequivocally, this is genocide! Genocide!

If it's unequivocal, why do opposing opinions exist?

From "gene" (as in DNA, genetic screening) and "-cide" (killing), litterally "killing a gene", in the most literal sense of the word.
> There was a news article recently published, that claimed that Iceland had eradicated Down's Syndrome. The mother runs through a battery of tests to determine if her baby has a genetic abnormality -- and if so, can choose an abortion. Unequivocally, this is genocide! Genocide!

I'm really interested in how you can categorize abortion of unwanted babies as genocide. I mean, I get it, they prevented DS babies from being born, ergo "eliminated a group of people", for generous definitions of people.

Would you say the same about preventing all babies from being born with fetal alcohol syndrome by having the mothers abort? What about having the mothers not drink when pregnant?

> I'm really interested in how you can categorize abortion of unwanted babies as genocide.

Sanger, 1924: "How are we to breed a race of human thoroughbreds unless we follow the same plan? We must make this country into a garden of children instead of a disorderly back lot overrun with human weeds."

Sanger, 1939: "The minister’s work is also important and he should be trained, perhaps by the Federation as to our ideals and the goal that we hope to reach. We do not want word to go out that we want to exterminate the Negro population and the minister is the man who can straighten out that idea if it ever occurs to any of their more rebellious members."

Sounds like eugenics and genocide to me.

> Would you say the same about preventing all babies from being born with fetal alcohol syndrome by having the mothers abort?

Yes.

Sanger was objectively a terrible person. That doesn't mean that abortion is a automatically immoral.

So you can equate terminating a pregnancy with that of murdering adults and children but unfortunately in reality it's a grey area. The older the fetus gets, the less grey it gets but there's no solid line to make it easy as much as conservatives would like to believe. Especially in cases of rape, or high-risk pregnancies.

It's a terrible decision to have to make, so I'm all for reducing the number of abortions. But you can't do that by outlawing abortion. And the side that wants to do that, outlaw abortion, also wants to pretend teenagers can "just not have sex" and that there's no need to teach them about safe sex, contraceptives, etc.

What you've done in this subthread breaks the site guidelines. Would you mind reviewing https://news.ycombinator.com/newsguidelines.html and sticking to them, no matter how right you are or feel you are about a topic? Note these:

"Eschew flamebait. Don't introduce flamewar topics unless you have something genuinely new to say. Avoid unrelated controversies and generic tangents."

"Comments should get more thoughtful and substantive, not less, as a topic gets more divisive."

There's always a bit of wiggle room but the line from https://news.ycombinator.com/item?id=25198407 (a fine HN comment) to "abortion is genocide" definitely intersects the outer boundary of the rules.

We detached this subthread from https://news.ycombinator.com/item?id=25198407.

With all due respect, I think you have read something I did not intend in this comment. Abortion is not necessarily genocide, but Iceland's specific application of it to those with Down's Syndrome is the textbook definition of eugenics.

I can clearly see how an unqualified "abortion is genocide" would be an unrelated controversy, but within the context, my point was to illustrate that a naive understanding of science as something that consumes data and produces a better society is also scientific illiteracy.

I was making more superficial points: (1) changing the subject to abortion already breaks the site guideline against generic flamewar tangents, and (2) a bomb-throwing word like 'genocide' is a flame multiplier that breaks the guidelines even further. Nothing good can come of this in an internet thread.
I suspect, somewhat anecdotally, that this begins with the educational system (at least in the US). Reflecting on my education, at least, it's remarkable how much of it boiled down to exercises in reading comprehension. Even many of my science classes were really just training my ability to read a passage and respond to a short answer question. There were many "alternative" math tracks offered--home economics you could take home economics after algebra 1, if you weren't a "math person"--and just generally, it was constantly reinforced that math was a specialization, not a fundamental skill.
This also isn't to suggest that the education system is the only thing at play here.
Actually the problem is not just that people don't know about science, they know so little that they don't know who to ask, either. Look at your local antivaxx FB group, they think Wakefield is authoritative.

I blame the education system. There's way too much specific knowledge that you will be tested on, and barely any theory of knowledge or scientific method fundamentals. And in the end, you will forget the silly quiz questions, leaving you with just the principles, if you were so lucky.

It would have been nice to have a general survey as well. "Not gonna quiz you on it, but FYI apart from the classic subjects that you are learning, there are also things like geology, materials science, a huge array of mathematical things, and so on. Just so you don't think that we had enough time at school to teach you everything."

> I blame the education system

This is a popular venue for blame, but perhaps you haven’t yet met the highly respected scientists claiming that masks don’t work against covid, that AIDS wasn’t real, or that vitamin C cures everything —- these are all highly educated people who, in their fields, have a deep understanding of “theory of knowledge” and “scientific method fundamentals”.

But, they are also human, and suffer from the human biases: confirmation bias, various selection biases like survivorship bias, etc.

These, I think, are more likely the culprits — and if you can figure out how to solve those within the education system, please share!

I have actually met medical doctors who believed in homeopathy. My point isn't that they wouldn't exist if things were taught properly.

For a start, schools could teach people about how we actually unravel truths from statistics. It's a bit unfortunate that one of the most famous books in the area is called "How to Lie with Statistics". But all those things you mention, did you learn them in school? No, you tend to learn the conclusions but not the reasoning behind.

> I have actually met medical doctors who believed in homeopathy. My point isn't that they wouldn't exist if things were taught properly.

What...is your point then?

The point is that your critical thinking journey is a journey. Yes, most people would think "oh, homeopathy in a doctor, what went wrong?" but what people should be doing is going through the thought process of what to believe about claims and evidence in the medical sphere.
How can an education system teach evaluating sources, and acceptable methods of evaluating facts, when those two things are at the heart of almost every disagreement in the areas we're talking about?

Fake news isn't just a meme, it's a belief system. So how does a public school system tackle that?

>Just so you don't think that we had enough time at school to teach you everything.

Is there literally one person (in the US) who leaves a basic 12th grade education believing that they learned everything there is to learn?

> How can an education system teach evaluating sources, and acceptable methods of evaluating facts, when those two things are at the heart of almost every disagreement in the areas we're talking about?

You can disagree about what the evidence is, or what it means, despite having properly followed the principles of reasonable inquiry. The issue is more identifying when those principles haven't been followed. The problem is that school doesn't really get into the tug-of-war between different strands of thought, it's quite parochial: you are told there are galaxies, not about the great debate that led to us knowing that.

> Look at your local antivaxx FB group, they think Wakefield is authoritative.

Every single individual within that group thinks "Wakefield is authoritative", and thinks that precisely and literally?

Might we be asking of others, that which we refuse to do ourselves?

What does science fiction have to do with this?

The real culprit is an established and generously funded PR - "public manipulation" - industry which is dedicated to misleading and misinforming the public in general, and lobbying selected politicians in particular.

Lead in petrol, smoking, toxic weedkillers, unsafe vehicles, and many other money-making aberrations have all been defended by these operations. Anti-masking and climate change denialism are just the latest toxic outputs from this industry.

It's very disappointing to see a scientist complain about scientific illiteracy and then attack the wrong people for it.

Nowadays I see much more overeducated people who are blind to obvious real life things, helpless, sick and overdependent on government.
Readers familiar with Quillette may wonder why such a level-headed essay by a somewhat well-known author appears here and not on the website of a more respectable publication. This is why:

https://www.theatlantic.com/science/archive/2018/10/lawrence...

It turns out that when people are kicked out, they don't just disappear. Dr. Krauss makes his point well; it's a shame the essay won't have the impact it should. But should he have that impact? I really don't know.

"Topic" illiteracy is acceptable because people can only know so much. Nobody ever talks about the illiteracy in terms of 'trees are air.' or 'lasers are focused light' both of which are not common knowledge. Most people think Trees come from the ground and lasers are focused sound.

"Scientific Illiteracy" is almost always not about knowledge but rather political policy. Or in his words "scientific facts people may remember."

That's why Amy Coney Barrett's vague non-answer is being construed as science illiteracy. While Kamala Harris is being portrayed as the winner. ACB is not giving any answer, she outright says she's keeping her nose out of the political issue. There's no answer whether or not she believes in climate change.

>Inappropriate claims like this by politicians who want to be on the right side of science but who can’t be bothered to think about what it implies don’t help.

I think this illustrates the problem. This isn't about scientific literacy, it's about politics. This has nothing to do with science.

Why is literature illiteracy so acceptable?

There’s two levels of scientific illiteracy. One is in the general population, but the general population also has, for example, literature illiteracy too. The other is the topic of C.P. Snow’s famous Two Cultures essay, where the generally well educated members of society are separated into those who know about science but not the humanities and the opposite. It certainly used to be the case that those educated members of society could discuss both topics. I’ve heard a claim that one thing is the replacement of any kind of ontology for science with mathematics (ie you don’t have a theory for why the world is but merely that some equations hold), and this mathematics isn’t easy—you need a lot more than school mathematics to understand Maxwell’s equations for example.

I think this whole topic misses the elephant in the room: STEM is a genetic lottery that our current economic and social system rewards with a better life and more resources. About 90% of the population are the losers in that game and they damn well know it. When humans get excluded like that, they often resent those who got the better deal and will work to nullify their advantage. With science, you can't really say "oh, that doesn't matter", so about the only realistic option is to not care about it, or proudly proclaim you don't know much about it, hence the behavior the author has witnessed. If society would even out the system, I would bet much of the impetus for this anti-science backlash would disappear.
The incapable correctly fear that the capable will use the power of their positions for their own ends. When you decide who to trust, you have to make a tradeoff between how competent they are and how likely you think they have your best interests at heart.
>STEM is a genetic lottery that our current economic and social system rewards with a better life and more resources.

I wonder to what degree that statement is flavored by tech tub developer salaries. A lot of scientists aren't especially well compensated compared to say stock traders. STEM does tend to lead to at least somewhat highish prestige occupations but it's not really a money/resources thing.
