Brian Williams reads and recites the above (2021)
What a vision.
Sounds like he just read history, noticed repeating patterns, and believed his own eyes. It sucks that makes him some kind of special person, instead of "people" just being the kind of thing that commonly does stuff like that.
Is it possible to get people to think critically and self-reflect, as a third party?
The answer to that question lies in the bottom of a cup of hemlock.
I don't know, man. I'm at a point where not even the tangible effects on me that the policies and decisions some members of my family endorse are enough to get them to think twice.
I can sit right in front of them and describe the problems I'm now dealing with and point out the exact legislative changes that caused them and it's like their brains turn off until the subject changes. More than happy to pray for me, though.

So openClaw bots are now even infesting HN with absolutely non-sense phrases ? WTF. Would be interesting what the recent stats on this say @dang / e.g. % new registrations since the claw-debacle, profiles with claw in their username , etc.

Not really. His prediction actually seems pretty off-base, with only some bits that are coincidentally correct. For instance, he seems to attributing the cause of that decline to superstition, when it was really capitalism infected by the shareholder-theory-of-value and financialization pursued by really smart and rational people focused on pursing their narrow self-interest.
I don't know the full context of that passage, but my read comports with my understanding of Sagan's biases.

I kind of agree. I find that almost everyone I meet has a firm grasp on tech topics affect their lives. From social media to privacy, they seem to understand the fundamental questions even though they aren't programmers or CISOs or whatever.
> capitalism infected by the shareholder-theory-of-value and financialization
For those who aren't inside the club, those are superstitions.
>> capitalism infected by the shareholder-theory-of-value and financialization
> For those who aren't inside the club, those are superstitions.
Come on, they are not. One is a value system, the other is a technology/practice.
I'd suggest reading David Graeber. Those aren't as categorically distinct as you're assuming.
Maybe I have too much imagination and stretched the rules a bit. But, if superstition is 'any belief or practice considered by non-practitioners to be irrational or supernatural', I'd argue that financialization is a consequence of an irrational belief in the power of the 'invisible hand' and that the shareholder-theory-of-value is a similar belief in the power of abstractions over actual human needs. Call it Friedman's invisible hand. I call these beliefs irrational not because they aren't profitable and effective - in certain environments for certain times - but because in the long run they will bring unenlightened practitioners and their subjects to ruin because they won't balance themselves and so they will be balanced by something else.
As economist Stevie Wonder once said, "When you believe in things that you don't understand Then you suffer Superstition ain't the way"
> when it was really capitalism infected by the shareholder-theory-of-value and fictionalization pursued by really smart and rational people focused on their personal self-interest.
That's one factor, sure. Another factor is the widespread rejection of mainstream science and consensus reality in favor of conspiracy theories that feed into populism and authoritarianism.
For all of capitalism's faults, you can at least have an educated society with technological and scientific progress under it. You can't have any of that when people who don't believe germs or real or who do believe wildfires are caused by Jewish space lasers are allowed anywhere near positions of power. When belief in imaginary satanic pedophile cults swing elections but actual pedophiles face no consequences. It doesn't seem entirely wrong to me.

I think you (and Sagan) are getting the causality backwards. Unrestrained capitalism doesn't serve people, it serves money. "Widespread rejection of mainstream science and consensus reality in favor of conspiracy theories that feed into populism and authoritarianism" is a reaction to an economic system that doesn't serve the common person and is very resistant to change.
Can you explain what it means for capitalism to "serve money"? That sounds exactly backwards to me; money serves capitalism, that is, it is the breath expelled when people speak the language of prices to understand each others' values.
I think it's also worth dilating on this notion of "unrestrained capitalism". Capitalism is after all a product of restraints, namely the enforcement of property, contracts, and the validity of money.
> Can you explain what it means for capitalism to "serve money"? That sounds exactly backwards to me; money serves capitalism, that is, it is the breath expelled when people speak the language of prices to understand each others' values.
Capitalism doesn't work to satisfy the wants and needs of the people in a society, generally. It works to satisfy the wants and needs of the people who have money, in proportion to the amount of money they have. If you don't have money but need something, Capitalism says "kindly FOAD." If you desperately need something, but a rich guy kinda-sorta wants it, rich guy gets it if he's willing to pay more.
So as inequality increases and wealth gets concentrated, a capitalist ceremony (without more restraints that we have) will increasingly neglect the needs of a large fraction of the people in society.
A lot of capitalism apologists assert capitalism is there to meet people's needs, generally (usually just lazily generalizing from US vs. USSR circa 1980), but that's only true under certain conditions which are not guaranteed. That goal is not part of its programming.
- Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives.
- See if you can find reasons for rejecting it. If you don’t, others will.
This is good advice IME. Get well acquainted (like REALLY well acquainted) with opposing viewpoints, such that you could argue them better than their proponents. See also "Argue Well by Losing" by Phil Haack [1].
Somewhat relatedly, the ancients viewed Rhetoric as the purest expression of intelligence. It required you to have deep knowledge of a topic, including all arguments in favour and against (implying deep empathy with the audience), and the ability to form coherent and meaningful argument. Modern political "debate" is ludicrous in comparison.
[1] https://haacked.com/archive/2013/10/21/argue-well-by-losing....
I always felt like Congressional debates should begin with each side trying to explain the opposing position, with debate only beginning when each side agrees with the opposition's framing of their PoV. I also recognize how naive and idealistic this sounds.
The public Congressional debates are performative, intended to curry favor with key voters, campaign donors, and media personalities. The substantive debates happen in private using completely different rhetoric. This is mostly fine in that it allows for policy decisions to move forward with compromises. The problem is that some members of Congress are unable to shut off their deranged public personas even in private back room negotiations.

"Rhetoric" is an unfortunately overloaded term, as modern political "debate" is often nothing more than (the other definition of) rhetoric.
I've also found simply testing a hypothesis without reasoning about it can quite often outdo your own reasoning and the reasoning of everyone else. Sometimes you are wrong, and everyone else is wrong, and only an empirical test can separate the wheat from the chaff.
Although maybe this method only works for me because I am a moron, and many people can out reason me, so the only way I can discover anything is to do something all reasonable and rational people are already sure is wrong.
I think the notion of considering all points of view depends on the assumption that people are arguing in good faith. When this breaks down, I don’t think we can just throw up our hands and give up, but the baloney detection kit needs to be updated. I don’t have a blog-worthy list of answers, but it’s something I at least think about.
One thing we can do is a kind of meta-analysis, where we check on the condition of our own baloney detection kit. For instance, if I reject an idea and it later turns out to be true, did my BDK fail? Does it need to be updated? Or are a few scattered failures OK? You can treat the BDK as a testable hypothesis like anything else.
While skeptical, he did not have much skepticism against mainstream theories.
I think it needs another item in the list: For any theory/ hypothesis: how well does it stand against the null-hypothesis? For example: How much physical evidence is there really for the string-theory?
And I would upgrade this one: If there’s a chain of physical evidence (was argument), every link in the chain must work (including the premise) — not just most of them
And when breaking these items do not mean that something is false. It means that the arguments and evidence is incomplete. Don't jump to conclusions when you think that the arguments or evidence is invalid (that is how some people even think that the moonlanding was a hoax).
> And I would upgrade this one: If there’s a chain of physical evidence (was argument), every link in the chain must work (including the premise) — not just most of them
We still use Newtonian physics plenty, despite bits of it not working due to relativity.
>We still use Newtonian physics plenty, despite bits of it not working due to relativity.
Absolutely. And since no one else has trotted this bit out yet, I guess it will be me:
All of our science is based on imperfect models of how the universe works. Every single one is wrong.
However, the models we use today are less wrong than those we used in the past. We know this because we (as you pointed out about Newtonian physics) can more accurately describe the universe than we were able to do previously.
That doesn't mean we've found "the truth." Nor does it mean that we have all the answers.
This is an important concept for baloney detection as those who are peddling baloney will (often, but not always) purport to know "the truth."
Anyone who makes such claims is either knowingly attempting to mislead or is lying to themselves and others.
Which, IMHO, is a pretty big red flag in baloney detection.
> While skeptical, he did not have much skepticism against mainstream theories.
That's tautological. The definition of a "mainstream theory" is one that is widely believed. And while, sure, sometimes scientific paradigms are wrong (c.f. Kuhn), that's rare. Demanding someone be "skeptical" of theories that end up wrong is isomorphic to demanding that they be a preternatural genius in all things able to see through mistakes that all the world's experts cannot. That doesn't work.
(It's 100% not enough just to apply a null hypothesis argument, btw!)
Really that's all of a piece with his argument. It's not a recipe for detecting truth (he didn't have one, and neither do you[1]). It's a recipe for detecting when arguments are unsupported by scientific consensus. That's not the same thing, but it's closer than other stuff like "trust".
(And it's 100% better th an applying a null-hypothesis argument, to be clear.)
[1] Well, we do, but it's called "the scientific method" and it's really, really hard. Not something to deploy in an internet argument.

From The Demon Haunted World:
"In the middle 1970s an astronomer I admire put together a modest manifesto called “Objections to Astrology” and asked me to endorse it. I struggled with his wording, and in the end found myself unable to sign—not because I thought astrology has any validity whatever, but because I felt (and still feel) that the tone of the statement was authoritarian. It criticized astrology for having origins shrouded in superstition. But this is true as well for religion, chemistry, medicine, and astronomy, to mention only four. The issue is not what faltering and rudimentary knowledge astrology came from, but what is its present validity.
...
The statement stressed that we can think of no mechanism by which astrology could work. This is certainly a relevant point but by itself it’s unconvincing. No mechanism was known for continental drift (now subsumed in plate tectonics) when it was proposed by Alfred Wegener in the first quarter of the twentieth century to explain a range of puzzling data in geology and paleontology. (Ore-bearing veins of rocks and fossils seemed to run continuously from Eastern South America to West Africa; were the two continents once touching and the Atlantic Ocean new to our planet?) The notion was roundly dismissed by all the great geophysicists, who were certain that continents were fixed, not floating on anything, and therefore unable to “drift.” Instead, the key twentieth-century idea in geophysics turns out to be plate tectonics; we now understand that continental plates do indeed float and “drift” (or better, are carried by a kind of conveyor belt driven by the great heat engine of the Earth’s interior), and all those great geophysicists were simply wrong. Objections to pseudoscience on the grounds of unavailable mechanism can be mistaken—although if the contentions violate well-established laws of physics, such objections of course carry great weight."
Acclaimed science author Carl Sagan illustrated this challenge with his “dragon in the garage” analogy. If someone claims to have a dragon that is invisible, silent, intangible, and undetectable by any means, there is no practical difference between the dragon’s existence and non-existence. Similarly, without verifiable evidence, the existence of an immortal soul remains unproven.

The dragon is just a gauge. Gauge symmetry
Good one!
>If someone claims to have a dragon that is invisible, silent, intangible, and undetectable by any means, there is no practical difference between the dragon’s existence and non-existence.
“Everyone knows that dragons don’t exist. But while this simplistic formulation may satisfy the layman, it does not suffice for the scientific mind. The School of Higher Neantical Nillity is in fact wholly unconcerned with what does exist. Indeed, the banality of existence has been so amply demonstrated, there is no need for us to discuss it any further here. The brilliant Cerebron, attacking the problem analytically, discovered three distinct kinds of dragon: the mythical, the chimerical, and the purely hypothetical. They were all, one might say, nonexistent, but each non-existed in an entirely different way.” ― Stanisław Lem, The Cyberiad
Love that book!
> If someone claims to have a dragon that is invisible, silent, intangible, and undetectable by any means, there is no practical difference between the dragon’s existence and non-existence.
Unsurprising that the longest subthread here is one criticizing the premise.
Doesn’t silent, invisible, intangible also apply to software?
You can’t really tell a particular piece of hardware is running software by a direct physical measurement. You can only infer that indirectly.
> Doesn’t silent, invisible, intangible also apply to software?
No. Because software is hardware.
> You can’t really tell a particular piece of hardware is running software by a direct physical measurement. You can only infer that indirectly.
You can literally step through code. Have you ever used a debugger or a profiler? You can dump memory, check the registers, read off the disk, etc.
If software was silent, invisible and intangible, you couldn't store it on disk, or copy it to memory. A computer wouldn't work if software was as you describe it.
Having debugged code with a logic analyzer, I'm pretty sure the voltage on those CPU pins is real, and really the consequence of the code I think I'm running.
This. Try it! LAs are cheap and easier to use than a scope, even if it has digital features.
If software were undetectable by any means, we'd have no way to run software or tell which software is running at a given time.
Software (that is running on hardware) isn't a great example - you'd be better off going with something like prime numbers. They don't really "exist" in the same way a toaster does. Souls also don't exist (citation needed etc) but are a similarly useful (for some people) way of thinking about the world.
Software can make sound, not silent, software can make things appear on the screen, not invisible, software can affect physical objects through device control, not intangible.
Nothing like an invisible dragon you might claim exists without any of the above.
As others are pointing out, this isn't true. You can absolutely infer the software state of a system via physical measurement.
But what's interesting isn't your mistake, it's why the mistake was made. The abstraction stack in software is really, really really thick. You don't normally "measure" your software, you add a log statement or run a debugger, and that's more software. And those debuggers aren't written over hardware, they're software too.
But eventually, you get down to the point where there really is hardware in the way. A debugger that tells you the content of a memory address really is, down the stack, doing a memory read, which is an instruction to hardware to measure the voltages in an array of inverter pairs structured as a level 1 SRAM[1]. Or it's setting a breakpoint or watchpoint, which are CPU features implemented in hardware, etc...
The hardware is always there, but we've done such a good job of hiding it that even practitioners are fooled into thinking it isn't there.
[1] And of course there's a stack there too. But read instructions hit the L1 cache.

What? Yes you can. I know my laptop is running a web browser because I can see it and interact with it. That's a physical measurement.
Won't be surprised if he's one of those that think "radiation" is some kind of harmful beams instead of also what the computer screen emits and we detect it to interact with it.
Only in the same way that it applies to, say, a tree. You can never observe a tree directly. All you can do is infer it from the nerve signals coming from your retinas and touch receptors.
The point of the dragon in the garage isn't that you can't measure it directly. It's that you can't measure it at all. It has no observable effects at all. Software definitely has observable effects, as do trees and almost everything else that people accept as real.
The dragon in the room is the hidden qualifier for "undetectable by any means" is "that is currently known to humanity".
That makes Carl Sagan's claim some what Balonish. Not sure why the smart Sagan fell for it.
> The dragon in the room is the hidden qualifier for "undetectable by any means" is "that is currently known to humanity".

The point is that if someone does claim that the dragon exists, they better be able to explain how they know it exists.
> That makes Carl Sagan's claim some what Balonish.
His claim wasn't that invisible dragons don't exist. His claim was that you cannot tell the difference between a dragon that doesn't exist and one that is, to use your qualifier, currently undetectable by any means known to humanity. If you cannot tell the difference between existence and non-existence of something, any claims to its existence are vacuous.
Your "argument" reminds me of this:
The Rabbit's Thesis
Scene: It's a fine sunny day in the forest; and a rabbit is sitting outside his burrow, tippy-tapping on his lap top. Along comes a fox, out for a walk.
Fox: "What are you working on?" Rabbit: "My thesis." Fox: "Hmmmmm. What is it about?" Rabbit: "Oh, I'm writing about how rabbits eat foxes."
(incredulous pause) Fox: "That's ridiculous! Any fool knows that rabbits don't eat foxes!" Rabbit: "Come with me and I'll show you!"
They both disappear into the rabbit's burrow. After a few minutes, gnawing on a fox bone, the rabbit returns to his lap top and resumes typing.
Soon a wolf comes along and stops to watch the hard working rabbit.
(Tippy-tap, tippy-tap, tippy-tippy-tap).
Wolf: "What's that you are writing?" Rabbit: "I'm doing a thesis on how rabbits eat wolves."
(loud guffaws). Wolf: "You don't expect to get such rubbish published, do you?" Rabbit: "No problem. Do you want to see why?"
The rabbit and the wolf go into the burrow, and again the rabbit returns by himself. This time he is patting his stomach. He goes back to his typing.
(Tippy-tap, tippy-tap, tippy-tippy-tap).
Finally a bear comes along and asks, "What are you doing?"
Rabbit: "I'm doing a thesis on how rabbits eat bears." Bear: "Well that's absurd!" Rabbit: "Come into my home and I'll show you."
SCENE: Inside the rabbit's burrow. In one corner, there is a pile of fox bones. In another corner is a pile of wolf bones. On the other side of the room a huge lion is belching and picking his teeth.
MORAL: It doesn't matter what you choose for a thesis topic. It doesn't matter what you use for your data. It doesn't even matter if your topic makes sense. What matters is who you have for a thesis advisor.
I think you missed his point. In that exercise, the justifications for the dragons existence are always shifting.
“Oh, it doesn’t show up on thermal? That’s because it doesn’t emit heat. It has special fire”
“Oh, when you spray flour in the air nothing sticks to the dragon? Well that’s because it is also incorporeal”
Skeptics keep asking questions. That’s the point. If you are never satisfied with any answer, you have no reason to believe the claim. There is literally nothing there to believe in.
His point is that skepticism and wonder go hand in hand. One without the other is dangerous. What a fascinating claim, an invisible dragon! It should not be dismissed outright as obvious quackery, but let’s see how much scrutiny it can take
We start with an invisible dragon and the more we look into it we now have to explain fire without heat, bodies without form, etc. gee, it seems that for this to be true our entire understanding of the world is wrong…or is the simple answer that someone is trying to trick us would answer this better.
Then the skeptic starts asking why someone would want to trick us…
Yes. The beauty is that once you get the means you can adjust your view. But you can't go just "trust me bro, it's there, you can't ever verify it, but I know it's there." It might be there... But why do you believe it to be so?
Do you actually live your life with the idea that there might be a dragon in your garage that is undetectable by any means currently known to humanity? And maybe an elephant in the neighbor's, and a unicorn down the street?

>Not sure why this comment got downvoted, but after all this is HN: very pro-tech while at the same time anti-science. Computers do everything so knowledge doesn't matter.
As Dr. Sagan (quite correctly) pointed out:
Extraordinary claims require extraordinary evidence.
1. Sagan's example was a metaphor for an unfalsifiable hypothesis;
2. Dragons (okay, kimodo dragons do, but that's orthogonal to the discussion) don't actually exist;
3. Even if dragons with the properties posited by Sagan actually do exist, Evidence must be provided to confirm the "garage dragon" hypothesis or it's irrelevant. If it cannot be detected, it may as well not exist.
While it's true that "Absence of evidence is not evidence of absence," not being able to verify the non-existence of something doesn't confirm its existence.
I suggest you use the rest of the tools provided in Sagan's "Baloney Detection Kit" (helpfully linked above) to help you get the point.
I'd also point out that the guidelines[0] say:

>It IS relevant to me and to most scientists. And you sound like someone who stops giving up at the first obstacle.
QFT posits that the graviton (as a particle-like excitation in a "gravity field") exists.
We do not currently (although there are some potential future experiments that might be able to confirm the existence of the graviton) have the means to detect gravitons.
Does the graviton exist? I don't know and neither do you. And we won't, unless and until we have the ability to detect gravitons. While we have a theoretical basis for gravitons, we have no experimental or observational evidence. Does that mean we should stop looking? No.
How about dark matter. What exactly is dark matter? We have a bunch of evidence that something that doesn't interact via the photon (the particle-like excitation of the EM field), but does interact gravitationally with itself and other fermions and bosons.
We don't know what that "dark matter" might be, but we continue looking for it, as there is both theoretical and observational evidence of its existence.
As for the "garage dragon," there is no theoretical, experimental or observational evidence for it.
There is also none of that for my claim of the absolute existence of a gremlin living inside your skull chowing down on your brain. But we should definitely saw open your skull to prove it, right? I'm partial to circular saws, but we can go with a chainsaw if you like.
>you sound like someone who stops giving up at the first obstacle.
It's not clear what ad-hominem attack you're making against me here as the words, as strung together don't make sense, but who I am or what I will or won't do is irrelevant to the discussion at hand.
Are you unable to make a better argument and so attack me personally instead?

You did a good job at making my point for me, thank you.
A parking lot dragon? This sounds familiar. [Assuming not a Dragon of Eden, nor one who farts nerve gas] I believe it is a parable about cause and effect; consistency of the world's state.
A parking garage, poured in modern times from reinforced concrete, might have been found to be structurally unstable during a renovation. If this turned out to be rooted in a massive [dragon, dinosaur, etc] skeleton being embedded in the concrete (As it was being poured?) surely this would be a contradiction, if people (workers, onlookers) witnessed the garage's construction.
There would be evidence from the reinforcement efforts; materials sourced to reinforce it due to structural flaws introduced by the skeleton; wear on the truck tires carrying them, memories in brains etc. If suddenly the skeleton were to have vanished, would there be logical consistency problems with the world state? Quite a thing to ponder!
I would like to clarify that this is purely a thought experiment. It is not possible that any group of people, no matter how secluded, could either A: Will such a reptile into existence while maintaining cosmological consistency, nor B: Remove it from our cosmos after evidence over its existence has propagated.

You could go one level higher with this observation, since "modern academia" is just another business.
Rephrased: A significant amount of businesses would dissolve if this was applied.
Almost all of religion would vanish too.
Sagan's kit is one of several similar resources I'd turned up ... over a decade ago now ... when I'd begun considering the matter of epistemics in media, particularly online discourse. The situation's not improved.
My catalogue is here: <https://web.archive.org/web/20200121211018/https://old.reddi...> (archive).
It includes in addition to Sagan: Rory Coker's precis on pseudoscience, the Venn Diagram of Irrational Nonsense, the concept of falsifiability, an informative (if excruciatingly painful) BBC docu on stupidity, Frankfurt's "On Bullshit", Ferguson on why youth culture made everything suck, Brandolino's Law, Silver's Bullshitter's Inequality, a relationship between the Kübler-Ross model and the Dunning-Kruger Effect, The Periodic Table of Irrational Nonsense, and Adams's 'B'-Ark.
I wonder how well Sagan's own "baloney" holds up against his kit. Historians despise the guy for all the stuff he made up about the library of Alexandria, Hypatia, Eratosthenes, etc... People still repeat a lot of that to this day.
Sagan made solid contributions to Planetary Science in the 60's and 70's.
His role as PBS educator, SF author, etc. needs to be considered as a separate thing.
I also loved James Burke and his Connections series, but as it got into the later seasons the so-called "connections" got tenuous and sometimes quite strained.
You can go through all the classic PBS science shows and find problems, Stephen Hawking's Universe was basically unwatchable because they refused to engage with the math.
People like Sagan have a worldview in which we are all either rational robots that only believe in "science", or else silly magic-believers that can't think by themselves. Of course Sagan himself proves that this is wrong: you can be a great scientist while believing a lot of silly nonsense about the ancient world, and about crab evolution apparently.
A lot to unpack here. He espoused a worldview where human beings are "star stuff", a way for the Universe to be self-aware.
And this worldview does not exclude spiritual thinking, it just channels it in a specific direction.
Yes, he said our brains are made from the same matter as everything else, but it does not follow that he espoused any sort of strict materialism.
The truth is more subtle and nuanced than that.
If you are interested in getting inside his head, I recommend reading the Mr. X article.
Believing silly nonsense which is still plausible isn't the same category of error as believing in magic.
Also I don't think skeptics hold the worldview you ascribe to them. You seem to have a particular grudge against Sagan.
I actually kinda like Sagan, Cosmos is seriously gorgeous (though Vangelis does a lot of the heavy lifting there). I'm just kinda tired of the whole "Library of Alexandria" myth that comes up constantly around nerdy forums such as this one.
> Believing silly nonsense which is still plausible isn't the same category of error as believing in magic.
Eh, hard to say what is magic and what is not. Sagan's beliefs about the ancient world could have been fixed with a five minute conversation with an expert. He just didn't care enough to do that, and for some reason that attitude is common among so-called skeptics when it comes to history.
>Eh, hard to say what is magic and what is not.
I don't think it is?
I had to look up what specifically Sagan's errors about history were and yes it looks like he popularized a lot of bad mythology (I referenced this site[0]). I have to admit I believed a lot of this myself at one time. But I think there's a difference between the plausible but wrong and the impossible. If he'd said he thought Atlantis was real, or gone on about Tartaria or the great Ice Wall, that would be a lot closer to magical thinking.
Although it is a lot easier to be led astray by plausible lies than implausible ones. It seems like Sagan is certainly guilty of not being critical about narratives that reinforced his worldview.

Did he make the stuff up, or did he get them from (now considered) poor sources?
I think "made up" is fair. I can't know what his process was and everybody makes mistakes, but almost every single thing he said about history was wrong in a way that was convenient to his narrative, and it's not like he ever retracted anything. Surely if he wrote a whole book about dealing with bullshit he could have used that opportunity for some reflection about his past mistakes, now that would have been interesting to read.
I just found out that his story about the Heike Crabs is also complete baloney. That makes me sad, it was really such a great story.
> I wonder how well Sagan's own "baloney" holds up against his kit. Historians despise the guy for all the stuff he made up about the library of Alexandria, Hypatia, Eratosthenes, etc... People still repeat a lot of that to this day.
Yeah, but he's a saint of science-fandom, so don't question him. Instead, admire and follow him, and encourage others to do likewise.
I loved watching Cosmos when I was a kid but as I got older I developed a dislike for Sagan. He strikes me as supremely arrogant and probably insufferable to be around. I don't know that of course, I never met him. Just a feeling.
I love this. I drill this into my children, they have it memorized.

In these fractious times, I think we're all very good at scrutinizing other side of the aisle, and not so good at self-reflection.
As a committed centrist, I am very good at fairly scrutinizing everything. /s
You joke but you’d be amazed at the Reddit front page. It’s hard to tell anymore if the comments are even people, but I have noticed many fake posts of some Trump tweet he never actually made getting traction.
It’s so easy to verify his public statements. Did he really say that? Just go look.
Yet time and time again people get baited into rage mode. It’s more satisfying to post than it is to do 30 seconds of research.
The people for whom this stuff isn't glaringly obvious, relatively early in life, will never get it. Except, maybe, specific instances that directly affect them in a bad way. Switch "brands" and they'll be fooled again. They'll probably even double-down on it.

How do you know this?
Yeah I hard disagree with their statement.
I've come to observe with having kids (and also moving to Germany and seeing other kids shaped) that so so much is taught. There is a ton born into a kid but so many things like the ability to think critically about a problem is actually taught in primary school and early years education (kindergarten/kita/preschool). There might be some raw horsepower that some people have more or less of with regards to certain problem spaces but for the most part - how to tackle a problem and think critically is very much a learned skill that some may get on their own but it can certainly also be given to them.
I concur with regard to critical thinking being a taught skill. My read is that parent's comment is possibly more of a vent about the type of person many of us have become more familiar with than we ever wanted to in the past decade or so of "post-truth" discourse- the virulent, intentional ignoramus. (We could write reams about what leads people to be this way, but in the interests of keeping short-form commentary short-form, I'll say that I think there are a confluence of causes :P).
People who can assert both "Fauci was wrong about masks" and "Nobody really died from COVID" come to mind.
I spoke in absolutes. Guess I'll say I've never observed it happening in anyone after maybe late teens. Some learn to keep quiet about whatever they're bought into, because they've learned it will scare a lot of people off. Or they end up pseudo intellectuals with a podcast. Or scamming their way into huge money and political positions. So they can be pretty good at "winning". But most of them are just sad and lonely, living mostly to prop up those "winners".
I've fallen for it enough to see it almost instantly now. So much time wasted, thinking some people just needed to figure things out, or maybe they figured out something I couldn't see. But, little by little, they just keep getting worse, more unreasonable, dangerous even.
Unfortunately, I wasted my youth on that idea. Now the people that warned me not to, moved on to much better things, far outside the environment I've been hanging out in.
Guess I'm just passing along the warning.
Hard disagree. I grew up with parents who LOVED science; my earliest memories in the 80s are my mom checking out Cosmos from the library on VHS and binging it. It is a big reason I have an engineering PhD. At the same time, they were 60s hippies and into meditation woo-woo, as in "visualize a beam of light coming from your stomach and you can instantly travel to Jupiter!", being able to walk through walls because of quantum physics, etc. Tons of pseudoscience. So, I grew up in both worlds, while always somewhat skeptical of the woo, still was sort of in it through high school. I read Demon Haunted World in college, and the woo was eradicated overnight. I think part of this also has to do with PhD programs, particularly reviewing papers, where it is basically BS detection. But, DHW framed it spectacularly for me, and is one of the most influential books I have read.
Another anecdote: Ann Druyan (Sagan's wife and collaborator) was into the wu herself!
Spot on. I just finished reading the demon haunted world to my daughter. She’s 13 and we have been very concerned about her going on social media.
I framed it as being more important than ever to be skeptical of what you see. Everything online is fake in some way. Every picture is touched up at best, AI slop at worst. You need to question everything.
I honestly fear her generation is just cooked. They were forced into online learning during covid, have socialization issues, and are coming of age in an era of rampant disinformation and generated content that is too good to spot and designed to addict and influence.
More than just question everything, but also develop a facility to answer the questions.
Otherwise it just means don't believe anything, which is more or less the same as believe everything, or believe & disbelieve things at random or according to wish.
