Culture War Roundup for the week of February 16, 2026

This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.

Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.

We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:

  • Shaming.

  • Attempting to 'build consensus' or enforce ideological conformity.

  • Making sweeping generalizations to vilify a group you dislike.

  • Recruiting for a cause.

  • Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.

In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:

  • Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.

  • Be as precise and charitable as you can. Don't paraphrase unflatteringly.

  • Don't imply that someone said something they did not say, even if you think it follows from what they said.

  • Write like everyone is reading and you want them to be included in the discussion.

On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

A Strong Argument Against Weak Men

I wrote all of this as a reply to @FCfromSSC 's defense against my critique of his critique of Devereaux’s critique of the "Weak Men, Hard Times"/"Fremen Mirage" thesis (try and keep that straight). It got out of hand. I put a lot of effort into it. So top-level post it is, even though it's primarily directed at him. You likely want to follow the link first.


Fair enough, I asked for concrete arguments and you've made an attempt at providing them. Forgive me for saying this, but I find it rather light on detail.

I'll start with "inevitable," because that word is quietly doing the work of three different arguments while dressed as one. You have two options. Either you mean it literally, in which case the counterexamples are immediate and fatal (and I'm going to share them), or you mean something like "tends to produce," in which case welcome to the world of probabilistic claims, where you owe us a measurable prediction: increases the probability of what outcome, by how much, measured how. Right now "inevitable" floats above the empirical fray like a philosophical dirigible, too vague to be shot down, too vague to be useful.

It also helps to be explicit about the three claims that keep getting quietly bundled together. As I see them:

  1. Morale and cohesion matter militarily. Correct, well-attested, Clausewitz built it into the load-bearing structure of his framework under “moral forces,” nobody serious disputes this. It's acknowledged in official US military doctrine.

  2. Culture can shape military performance in meaningful ways. Also largely agreed, also case-specific, also entirely compatible with Devereaux’s thesis.

  3. Hardship reliably produces superior fighters and drives predictable civilizational cycles.

That third claim is the contested claim. That is the meme. Conceding the first two does not move the needle on the third by even one tick, and yet your argument keeps treating “morale matters” as if it's a portal that gets you to “hard times generate conquerors.”

(How exactly do you rule out the possibility that Good Times also generate Strong Men at similar base rates, but those men don't get the opportunity to do much raping, pillaging and conquering because of the restrictions put upon them by a functional society? Or because they're quite happy with how things are going?)

I will admit to a certain sympathy for the "Hard Times" thesis, one that was beaten out of me by reading actual history. It appeals to a very specific, conservation of energy intuition we all seem to share share. It feels like physics applied to sociology. If you put a human being under immense pressure, they should turn into a diamond. If you put a human being in a warm bath with a steady supply of peeled grapes, they should turn into soup. The universe seems requires a trade off between comfort and capability, so it makes sense that a civilization maximizing comfort would bleed capability.

But if you're going to accuse Devereaux of baking absurdity into his arguments, it's desirable to at least check whether the hard-times model actually predicts anything.

If hard times make strong men inevitable, then the places experiencing the hardest times should be the places producing the strongest men, and by the meme’s own implication, the most formidable military actors.

Hard times are not hard to find. Somalia has had a shit time since 1991. North Korea is so chronically deprived that the population is physically shorter than their southern neighbors. Haiti is a recurring disaster. Eastern Europe is literally eating trench warfare again.

Does the hard-times generator produce strong men in the way the meme implies?

It certainly produces tough men. I do not doubt that a survivor of the Somali civil war has a tolerance for pain, a resilience to trauma, and cockroach-adaptability that would shatter the average San Francisco software engineer in 48 hours. If “strong” means “hard to kill individually,” then yes, hard times can produce hard shells.

But the Fremen Mirage is not about individual survival. It's about civilizational competence and military victory. The meme posits that these hard men will inevitably conquer the weak men of the good times.

Yet Somali pirates do not win fights against destroyers, probably not even against a PT boat. Beef-feed American boys grow up playing Halo with an Xbox controller and have no issues using another Xbox controller to turn them into a halo of fine mist. North Korea is unlikely to win any military victories in the foreseeable future (maybe if all the South Koreans end up in retirement homes, but isn't the grind and rigidity of the latter culture itself a form of "strength"? They've got mandatory conscription, how hard is that?). Ukraine is a meatgrinder that turns sunk cost into well-fertilized and mined sunflower fields.

And here is where the model fails to predict the past two thousand years of warfare better than chance (and in fact, worse than chance), and fails even harder in the modern era.

When the soft, decadent, weak United States military engages with forces bred in the hardest of times, the exchange ratio is often lopsided to a degree that defies belief (and draws accusation of war crimes). The hard men die in droves, often without ever seeing the "weak men" who killed them from an air-conditioned control room. The North Korean soldier, bred in the hardest of times, is not a super-soldier. He's a poor bastard with intestinal parasites, brittle bones, and a rifle from the 1960s. In power-projection terms he is not strong.

Look at Venezuela. I strongly suspect that you are rather focused on American affairs, so let's look closer:

Venezuela got clapped. No contest, no lube. It's a historical humiliation of near unprecedented chutzpah, and a military masterstroke. Putin probably believes he's a hard man ruling hard men, and he wishes his 3 day special operation was a tenth as effective. Grit ain't nothing compared to total air superiority.

Going back, there's an even more glaring example in WW2:

The Japanese were the archetypal hard men.

If any modern society ran the Fremen playbook sincerely, it was Japan. Institutionalized martial culture, explicit civilizational contempt for comfort and luxury, bushido as doctrine, genuinely formidable individual bravery. No proxies. The hardness was real, rigorous, and deeply embedded.

Their men expected no quarter, and gave none. Their pilots showed a willingness to convert their planes and bodies into guided missiles without a parachute. They dug in like Alabama ticks and fought like hell till their blood pooled in the mud.

And yet, once again, they got clapped. By the richest and most "decadent" nation around. While the Japs ate thin gruel and Germans were making ersatz-coffee, the US had entire ships dedicated to ice cream for its troops. By virtually any Fremen metric, the United States was the most materially comfortable, consumerist, pluralist fighting force in recorded history. The kind of civilization the meme would predict to crumble at first contact with anything properly hard. Dare I say, the most decadent?

Huh. Funny how that works.

Before you bring up Vietnam or Afghanistan, I will keep it simple: in the past century, the US has not lost a single war that mattered. The safety and comfort of the homeland, the F-35 flybies over college football stadiums? None of that was ever in jeopardy. Your wars were toy-wars, usually fought with one side following gentleman's rules (you). You pissed away the GDP of entire continents on dirt that barely grows poppies and didn't even get dehydrated in the process. Even victory would have, in hindsight, been largely inconsequential.

It is far from obvious that any other force can overturn this, if your closest competitor, China, has any hope of a victory in the medium-term, it'll be on the backs of the industrial capacity to produce a bazillion missiles and drones, not the grit of their soldiers or the genius of their generals. And yet they don't even dream of landing an expeditionary force on the US mainland. A potential victory (emphasis on potential) hinges on industrial capacity, not moral character.

Looking at your claims about “free energy,” which I think has the causality backwards: Good times are not a reduction in the energy available to strong men. Good times are the surplus that makes strength scalable.

Good times, meaning surplus calories, high GDP, technological capacity, lack of immediate existential threat, allow a society to take a percentage of its population and tell them: you don't need to farm. You don't need to hunt. You don't need to worry about where your next meal is coming from. You will spend twelve hours a day lifting, drilling, training, learning complex machinery, building unit cohesion, practicing logistics, rehearsing doctrine.

That is how you build a Roman legionary. That is how you build a US Marine. The hard man from the hills has to spend his energy surviving. He is a part-time warrior because he is a full-time survivor. The soft man from the empire is a full-time professional killer subsidized by the very economic complexity you are sneering at.

But in actual fact it is obvious that Morale and Morals/virtue/character, are pretty clearly linked, and that even central examples of Moral Purity in the sense he frames it have in fact been used historically to build winning armies.

Your Cromwell example does not prove as much as you want it to. Yes, moral conviction and ideological zeal can be force multipliers. Asabiyyah is real. Morale matters. Nobody disputes this. I'm not disputing this, Devereaux isn't disputing this.

But Cromwell’s army was effective not because they were ragtag survivors of collapse. They were effective because they were paid, equipped, drilled, and organized according to cutting-edge military science. The New Model Army was a product of high coordination inside a relatively wealthy society. Zeal multiplies competence. It doesn't replace it.

Now, decadence.

You accuse Devereaux of refusing to engage with the semantic content of decadence. That is not quite right. Devereaux engages a specific operationalization: luxury softens bodies, literacy softens minds, complexity demilitarizes populations. Your complaint seems to be that this is too crude and that a richer version is hiding behind it.

Fine. Name it.

I'm serious. What is your definition of decadence, and is it of any use for predicting the course of history?

As I say (because it's true), "all models are false, some models are useful". The better models are differentially useful. They cut reality at the joints and serve as useful compression of complex systems, and more importantly, predict future events. At the very fucking least, they should describe history.

Back to Rome (it's my Roman Empire):

Decadence, as it is usually deployed, is almost always defined tautologically:

  1. Rome fell.

  2. Therefore Rome was decadent.

  3. How do we know Rome was decadent?

  4. Because it fell.

If Rome had repelled the Goths (and then were wiped out by a convenient asteroid so I don't have to write a full alternate history), as they had repelled Germanic tribes for centuries prior, often while being just as wealthy and just as bath-loving and just as bookish, we would currently be writing essays about how civilized discipline triumphed over disordered barbarism.

As I said in my original reply, an empire needs an unbounded number of victories to survive. In the worst case, it only needs a single defeat to crumble.

This is also why the unfalsifiability problem runs like a hairline fracture through your whole framework (or at least the HTHMWTWM theory as popularly understood, which is what Devereaux is dismantling).

Rich state wins? Material advantages masked decadence temporarily. Poor state wins? Fremen thesis confirmed. Rich state loses? Decadence, obviously. Poor state loses? Not hard enough, or the material gap was too vast. Every outcome is accommodable. Every counterexample has an epicycle preloaded. A theory structured this way is not doing historical work. It's a just-so story that could be replaced by a well-decorated rock. At least I can kick a rock.

It's the equivalent of saying "what doesn't kill you makes you stronger." Sounds great, doesn't help when you transect your spinal cord in a car crash, or ruin your knees after too much PT. A claim being "inspiring" is very different from it being true.

The more I squint, the more this becomes the Just World Fallacy wearing combat boots. It suggests that suffering has a purpose (to make us strong) and that comfort is a sin (that makes us weak).

The universe is often far more cruel than that. Sometimes hard times just break you. Sometimes suffering is just suffering. Sometimes the "Hard Man" fights the "Soft Man," and the Soft Man presses a button and deletes the Hard Man from existence, because the Soft Man spent his "Good Times" studying physics and engineering instead of learning how to endure hunger.

What's probably true: character matters, organizational culture matters, genuine commitment to a cause produces measurably better outcomes under certain conditions, and a civilization that cannot articulate what it's fighting for faces real disadvantages at the margin. I'd go further and say that the Athenians, the decadent, democratic, philosophizing, play-writing naval-gazers, are actually the better case study than the Spartans here. They bounced back from defeat after defeat because their "Good Times" culture was dynamic enough to reinvent itself. The Spartans, the hardest men in Greece, ossified and collapsed precisely because they were so committed to their own hardness that they couldn't adapt to a changing world. They were too busy attacking their own allies, diddling boys and randomly killing the slaves that tilled their fields. The very quality the meme valorizes became their brittleness.


Miscellaneous thoughts, because I'm tired after studying all night:

It is helpful, and I would say good practice, to operationalize and define terms, especially those in contention. Devereaux does this well, he lays out a specific argument commonly found in the wild, and musters an offensive on every front. You do not do this. You haven't defined terms, at best you wave at your (implicit, unknown to us, or at least me) definition of "decadence", of "weakness" and "strength". A proper debate requires that both sides leave enough rope to hang each other with, and that the loser is sporting enough not to offer shoe-laces instead.

Is self-sufficiency and flexibility a bad thing? Is there such a thing as overspecialization or excessive complexity as legible cultural problems? Are the average men in societies, populations, or tribes more or less capable of becoming soldiers en masse, due to the culture they've been shaped by? Does this problem show up even from the perspective of men who appear to, in fact, be quite strong? Fuck that noise, questions are for dweebs! Let's round it to "all men in the society are warriors", that sounds way less complicated.

You are making up people to be mad at. At the very least, you are putting words in Devereaux's mouth, and as far as I can see, he never said what you claim he says, nor does he imply what you think he implies. Please, a quote where he even implies that asking such questions is "for dweebs" would go a long way. The man is a military historian focusing on classical history, I'm sure he's on the side of the dweebs and nerds.

To reiterate: he lays out an argument. He shows that the argument is shite. He is attacking a strawman, but unfortunately, the majority of people making that argument have straw for brains. The actual Motte doesn't need defending because it's nigh impregnable. You can't attack a critique of Lizardman conspiracy theorists on the grounds that he hasn't addressed the steelman version: humans and dinosaurs have a common ancestors, at some point before the split between synapsids and diapsids. Nobody disputes that. Nobody cares. A non-negligible number of people adhere to the batshit crazy version.

Devereaux is careful to avoid cherry picking evidence. His analysis spans roughly the entire history of the united Roman Empire, and then its Western successor. That is hardly cherry picked, both because Rome is usually held up as the example of decadence killing a civilization and because that's literally his field of scholarship. That is the breadth and depth of scholarship to aspire to, when discussing something as complicated as grand patterns in world history and the rise and fall of empires. I don't expect you to do that much, but come on.

More recently, we have the truism that "no one is going to fight a war on behalf of an economic zone." While we haven't tested this principle hard yet, I know which way I'd bet.

I recall a lot of blood spilled in the Age of Colonization, over what can loosely be termed as economic zones. It is unclear whether the US would, say, bat for Taiwan in a hot war with China. But it is unclear, and even then, a single sparrow does not a summer make. Devereaux throws a net over the whole swarm, you don't. I'm not aware of a rebuttal that does. Besides, I think China would have words for someone invading Shenzhen or Hainan, and what are those but economic zones? Rather special ones even.

By contrast, it seems to me that Devereaux aims to convince his readers that military affairs are largely deterministic, with a layer of luck on top. Therefore, empires are born because they got a streak of good RNG hits, and Empires die because they got a streak of bad RNG hits, and human decisions are not really terribly decisive either way.

And this is incorrect because? I do not see Devereaux putting numbers on the relative importance of "RNG" versus determinism. Rome might have been very different if Justinian didn't have to face one of the worst plagues in human history, and if Belisarius's wife hadn't been such a hoe. What might the world look like if Barbarossa took swimming lessons? He notes that macroscopic factors like population size, wealth and military metrics matter, he does not claim that nothing else does. I do not see why you consider it an excuse to insert your own interpretation and then get mad at him. My understanding is that he sees those metrics as important, often decisive, which is not the same as what you seem to believe. And randomness only adds variance. Devereaux believes systems (logistics, tax bases, agriculture) determine the probability of victory. It isn't just "luck"; it is that a "decadent" society with a 90% win rate due to logistics will eventually crush a "hard" society that relies on a hero rolling a natural 20 every time. (Numbers my own, and made up).

Finally, you accuse him of being a propagandist. On what basis? What basis in fact? Do your facts weigh up to his? He's got plenty. I've got plenty. Propaganda can be both propaganda and true (I do not agree that his approach to the Fremen Mirage constitutes propaganda). You need to demonstrate that it is both misleading and factually incorrect.

(Posters advising people to wash their hands are propaganda posters, but you're better off doing as they say)

If you insist on treating your arguments as soldiers facing off against Devereaux while declaring him an enemy propagandist, you had better hope your arguments are good soldiers. I remain unconvinced that they are.

I think I have put enough effort into concrete disagreement to risk slightly uncharitable psychoanalysis: you disagree with his thesis because it goes against your values, and this is more the cause of your discontent and disdain than its actual bearing on the truth. I suspect you are deeply unhappy with the status quo, and see bloodshed, strife and suffering as necessary for a phase transition to your ideal sociopolitical system, and that it helps to imagine that that suffering is inherently or terminally good in of itself. I hope to be proven wrong.

TLDR:

If decadence is defined as the cultural conditions that cause military decline, then the Fremen thesis becomes true by definition and empty of predictive content. For it to be a real historical claim, decadence needs to be identifiable independently of military outcomes, and then shown to strongly correlate with them. I do not believe this has been demonstrated, and I strongly doubt it can be demonstrated (because it's not true).

Decadence is the cultural conditions enabled by prosperity that cause dysgenics. Hard times can be, but are not always, eugenic. The Black Death, the high mortality during the Middle Ages, the violent organization of the early Roman Republic all served eugenic functions- even the collapse of the Roman Empire served an important eugenic function. "Hard times create strong men" is a nod to the eugenic function of growth and the dysgenic effects upon realization, stagnation, and ultimate decline. Goethe:

The Godhead is effective in the living and not in the dead, in the becoming and the changing, not in the become and the set-fast; and therefore, similarly, the reason is concerned only to strive towards the divine through the becoming and the living, and the understanding only to make use of the become and the set-fast.

You can see the full "Hard times create good men, good men create week men" cycle in the genetic evolution of the Roman Empire, with the collapse of the Roman Empire forming an important eugenic function reversing the dysgenic effects of late Roman decadence.

My brother in $Deity, if the cost of eugenics is painfully killing off 30% of the population with pestilence and plague, I'm not sure I want to take up that offer. That's coming from someone who is sympathetic to the cause of eugenics, done sensibly. We can do it with much less societal disruption by far more genteel approaches such as germline gene editing. No need to cause civilizational collapse, civilization is kinda nice, most of the time.

Citations desperately needed. I've never needed them more, because your claims warrant them. What fucking eugenics? Are you aware of the fact that the same genes that convey resistance to the Black Plague also cause increased risk of autoimmune disease? War, starvation and apocalyptic disease are terrible ways to go about it. All you've done is attach a chart that shows some kind of distributional shift of what I can only assume is some allele or haplotype. I find it incredibly funny that you chose to provide citations for the one thing you claim that least needs it.

Are you aware of the fact that the same genes that convey resistance to the Black Plague also cause increased risk of autoimmune disease?

Are you aware those genes don't simply convey resistance to the Black Plague, they provide more generalized resistance against lethal infectious diseases?:

These results suggest that the Black Death influenced the evolution of the human immune system. “When a pandemic of this nature—killing 30 to 50% of the population—occurs, there is bound to be selection for protective alleles in humans,” Poinar says. “Even a slight advantage means the difference between surviving or passing. Of course, those survivors who are of breeding age will pass on their genes.”

And recall the Native Americans were devastated by diseases for which Europeans had developed immunity. It provided a strong genetic advantage.

The Black Plague certainly impacted all classes of people, but the poor masses were hit harder, which yes would be another selection effect suggesting eugenic pressure. Higher immunity among higher social classes is observed even today.

Scholars cite the pressures created by the Black Plague on the Catholic Church as being decisive in the Protestant Reformation in Europe, and in the breakdown of feudalism in England towards the manorial economic system which then gave way to the market system.

I already cited the genetic trajectory of Rome (genetic decline -> civilizational decline), granted that bakes in the assumption that population replacement from North Africa was dysgenic, and the subsequent correction towards Northern Europe was eugenic. But it did happen that way.

War, starvation and apocalyptic disease are terrible ways to go about it.

If you took away war, starvation, and apocalyptic disease from our evolutionary timeline we would be devolved and unrecognizable and not human. Not saying I support all those things, but the eugenic effects of these sorts of pressures: war, disease, etc. lends credence to the "hard times create strong men" meme, but it's not always true. The pressure has to be eugenic in nature to ring true. Somalis living in a shithole isn't going to make better Somalis unless there's a eugenic selection effect. "Hard times" that are also dysgenic do not make good men.

Are you aware those genes don't simply convey resistance to the Black Plague, they provide more generalized resistance against lethal infectious diseases?

That is not information conveyed in the article you linked. The primary protection is against Y. Pestis, I went to the trouble of looking and I find no evidence of significant protection from other pathogens, at least for the ERAP2 variant in question.

As the article confirms:

However, the protection against plague conferred by these variants appears to have come at a cost. The protective ERAP2 variant is also a known risk factor for Crohn’s disease. Another protective variant has been associated with an increased risk of two autoimmune diseases. Thus, the Black Death and other past pandemics may have shaped humans’ immune systems in ways both good and bad. While we acquired better protection against infections, we became more susceptible to autoimmune diseases.

Yeah. It's a tradeoff. What would you rather have, a genetic resistance to Y. Pestis that is far from perfect, and obsolete with the age of antibiotics, or elevated risk of Crohn's disease, which is chronic and lifelong?

And recall the Native Americans were devastated by diseases for which Europeans had developed immunity. It provided a strong genetic advantage.

They were doing just fine before being exposed to alien pathogens. And the Europeans probably picked up syphilis in the process. I don't see how this improved things for anyone.

The Black Plague certainly impacted all classes of people, but the poor masses were hit harder, which yes would be another selection effect suggesting eugenic pressure. Higher immunity among higher social classes is observed even today.

That is much more likely to be a consequence of improved nutrition and sanitation. The wealthy also had the luxury of flight in the face of the plague. They also, yes, probably have better genes for physical and mental health overall, but probably not to that drastic an extent.

Scholars cite the pressures created by the Black Plague on the Catholic Church as being decisive in the Protestant Reformation in Europe, and in the breakdown of feudalism in England towards the manorial economic system which then gave way to the market system.

That's fine.

I already cited the genetic trajectory of Rome (genetic decline -> civilizational decline), granted that bakes in the assumption that population replacement from North Africa was dysgenic, and the subsequent correction towards Northern Europe was eugenic. But it did happen that way.

Yes, and you need to justify that assumption better. North African Berber populations are not the same as the people further south, the Sahara Desert is remarkably inconvenient. There has been a great deal of population admixture over 1.5 thousand years, so a naive extrapolation from current IQ figures is fraught.

If you took away war, starvation, and apocalyptic disease from our evolutionary timeline we would be devolved and unrecognizable and not human. Not saying I support all those things, but the eugenic effects of these sorts of pressures: war, disease, etc. lends credence to the "hard times create strong men" meme, but it's not always true. The pressure has to be eugenic in nature to ring true. Somalis living in a shithole isn't going to make better Somalis unless there's a eugenic selection effect. "Hard times" that are also dysgenic do not make good men.

It is a very good thing we have options these days, like gene therapy as I've mentioned previously. We do not need war and disease to trim the herd, it's a horribly crude solution at best.

Even in the absence of civilizational collapse, selection pressures were still present. In the absence of modern medicine, disease was rampant. Wars still killed people, albeit at a lower background rate. I wouldn't accept the trade of setting back living standards and tech levels so hard it took a thousand years to recover, during the late Enlightenment or early Industrial Revolution.

Yeah. It's a tradeoff. What would you rather have, a genetic resistance to Y. Pestis that is far from perfect, and obsolete with the age of antibiotics, or elevated risk of Crohn's disease, which is chronic and lifelong?

The question is what would I have preferred my ancestor to have had who was actually living in that time and place? Obviously I'm still here, meaning all my ancestors survived all that war and disease to reproduce. If they did not have that variant there's a higher likelihood I am not here.

They were doing just fine before being exposed to alien pathogens

They were doing just fine until.... they met other people. That's a great evolutionary strategy. They didn't have to survive those apocalyptic diseases like Europeans did, and they melted on first contact with the outside world.

The wealthy also had the luxury of flight in the face of the plague. They also, yes, probably have better genes for physical and mental health overall, but probably not to that drastic an extent.

Yes they did, and I am saying that was a selection pressure, as ugly as it is to say. The overall quality of the survivors is higher than the population before the event. That is the definition of eugenic.

It is a very good thing we have options these days, like gene therapy as I've mentioned previously. We do not need war and disease to trim the herd, it's a horribly crude solution at best.

I feel like you are refusing to understand what I am trying to say. I am not trying to say "war and apocalyptic diseases are good options today to improve society." I'm saying very real selection effects from these high-mortality events lend credence to the "hard times create strong men" meme and "good times create weak men" adage, but do not guarantee that a people living in a miserable situation will always become better for it. "Hard times" are often, but not always, associated with major historical genetic changes. In the case with Rome the genetic changes follow the cycle well from end-to-end: Latin tribal upstarts raise hell on the Italian peninsula, create strong imperial genetic stock and Civilization. Civilizational success leads to decadence: importing slaves from all over the world, population replacement, decay of Noble status and lineage. Decadence creates stagnation and decline. Decline creates a genetic cleansing event that creates the modern European/Italian and progresses to the Middle Ages, where these cycles of pressure continue until we are here today.

I understand what you're trying to say. I've noted the points of agreement and disagreement. The most specific is the claim that the change in population after the collapse of Rome was dysgenic, and that the specific adaptation to the Plague was a net positive after the plague subsided. That might be true, but definitely needs more evidence to be more than a possibility. The selection pressure wasn't so high that the protective allele became predominant, and that's despite Bubonic plague being a recurring problem.

My gripe is with the claim made (by others) that the cultural consequences of "hard times" are positive on net. It is also true that selection pressure strong enough to overcome genetic drift will produce adaptations that might be eugenic, depending on the context. For example, the protection provided by the mutant ERPA2 is probably dysgenic now, since we don't really have to worry about the plague but can't cure Crohn's.

More importantly, the advocates for the Hard Times thesis often want to intentionally cause suffering and hardship, because they think that's good. Even if it's debatably eugenic, the juice is clearly not worth the squeeze.

I do not lightly agree with SecureSignals about anything, but I think he has a point that you'd misunderstood his claim: while it may be true that some advocates for the meme want to intentionally cause Hard Times, Signals had bee fairly clear that he wasn't making that point, merely the retrospective claim that historically, as a matter of fact, Hard Times have produced Strong Men via eugenics - whether or no that was "worth it" and whether or not that would or should still work today.

The most specific is the claim that the change in population after the collapse of Rome was dysgenic

You have that backwards.

Latin warlords conquer Italian Peninsula: "Hard Times" that create good men (From frame A towards B, essentially genetic replacement of Early European Farmers with Indo European colonizers).

Genetic Changes during Imperial Rome: "Good times" that create weak men (From From B to Frame C). Decadence, dysgenic cultural practices enabled by prosperity: fertility decline, population replacement, decay of noble status and lineage. Huge genetic shift in the population.

Late Antiquity: "Weak mean create hard times" - From Frame C to D and onwards, imperial Rome collapsing and being genetically cleansed by the barbarians.

Medieval and Early Modern: "Hard times create good men": Genetic changes from Imperial Rome are reversed, genetic foundation for the next phases of European culture.

I apologize. I misread:

I already cited the genetic trajectory of Rome (genetic decline -> civilizational decline), granted that bakes in the assumption that population replacement from North Africa was dysgenic, and the subsequent correction towards Northern Europe was eugenic. But it did happen that way.
