Even in our supposedly enlightened times, “Is it a boy or a girl?” is still the first question asked of nearly every newborn — and the answer continues to shape how the child is raised. Research shows that from infancy, boys and girls are touched, comforted, spoken to, and treated differently by parents and caregivers. These early experiences may reinforce sex-typical patterns of behavior that often persist into adulthood.
People are intrinsically fascinated by psychological sex differences — the average differences between men and women in personality, behavior, and preferences. Psychologists have studied this topic systematically for decades, beginning with landmark works like The Psychology of Sex Differences (1974) by Eleanor Maccoby and Carol Jacklin. That book helped spark a wave of research that continues to this day. Since then, increasingly sophisticated methods have enabled researchers to detect subtle but consistent differences in how men and women think, feel, and act.
Men and women use language and think about the world in broadly similar ways. They experience the same basic emotions. Both seek kind, intelligent, and attractive romantic partners, enjoy sex, get jealous, make sacrifices for their children, compete for status, and sometimes resort to aggression in pursuit of their interests. In the end, women and men are more alike than different. But they are not identical.
To be sure, sociocultural influences play a role in creating those differences. But environmental factors don’t act on blank slates. To understand young men and young women, we must consider not only cultural context but also evolved sex differences. We are, after all, biological creatures. Like other mammals, we share similar physiology and emotional systems, so it’s not surprising that meaningful differences exist between human males and females.
To understand why psychological and behavioral sex differences evolved, the key concept is parental investment theory, developed by evolutionary biologist Robert Trivers in 1972. The basic idea is straightforward: the sex that invests more in offspring tends to be more selective when choosing a mate. This selectivity follows basic evolutionary logic: those with more to lose are more cautious and risk-averse. To put the stakes in perspective: raising a child from birth to independence in a traditional, preindustrial society requires an estimated 10 million to 13 million calories — the equivalent of about 20,000 Big Macs. For women, reproduction is enormously expensive.
Men also incur reproductive costs, though of a different kind. On average, they have about 20 percent more active metabolic tissue — such as muscle — that fuels their efforts in competition, courtship, and provisioning. While pregnancy requires a large, immediate investment from women, men’s reproductive effort is more gradual, spread out over a lifetime. In evolutionary terms, both sexes pay a price for reproduction, but in different currencies — women through gestation and caregiving, men through physical competition and resource acquisition.
Yet while nature can inform our understanding of human behavior, it does not dictate how we ought to live. A clearer grasp of sex differences can help guide our decisions. It cannot define our values.

QotD: “Is it a boy or a girl?”
November 9, 2025
Sir Arthur Currie, commander of the famous Canadian Corps in WW1
As a counterpoint to the OTT summary of Sir Arthur posted last week, here’s The Black Horse with part one of a two-part look at the man’s early career before joining the Canadian Expeditionary Force in Europe:
Sir Arthur Currie with Field Marshal Sir Douglas Haig, February 1918.
Libraries and Archives Canada item ID number 3404878.
The Red Ensign is a publication deeply interested in leadership; the good, the bad, and the ugly. For this reason, this Remembrance Day, I have chosen to draw the audience’s attention to the life and times of Sir Arthur Currie, the first Canadian commander of the Canadian Corps during the Great War. This presents an opportunity to both on honour and reflect upon the courage and sacrifice of the men who have fought under the flag of this great nation, but also offers the language to articulate the task facing any who would attempt to lead Canada today. As Currie’s war was defined by the challenge [of] leadership of Canadians in the context of the shifting priorities of the late British Empire, any who would seek to lead Canadians today face will struggle to harmonize efforts on behalf of the Canadian people and the priorities and policies of the American power block which he cannot eschew.
Dulce et decorum est pro patria mori; but when your country is an Imperial Dominion, who and what is “pro patria“, and how can one spend their life for them?
The Man Before the Great Man:
Arthur Currie was born in 1875 in Napperton, Ontario [50 km West of London], the third of eight children living on a homestead belonging to his grandfather. Raised with a the vigorous discipline of a Methodist home, Currie would remain a convicted Christian for his entire life, though he converted to Anglicanism as an adult. Currie was a good student, intending to pursue a career in law or medicine but dropped out of school twice, first temporarily because of the financial constraints brought on by the death of his father, and then for a second time at 19 because of a quarrel with one of his teachers. After leaving school he went West; after a string of failed efforts to establish himself via entrepreneurship and real-estate speculation he joined the Canadian militia as a gunner in 1897 in Victoria B.C. at the age of 23. A giant man (6’3″ at a time when the average Canadian height was 5’7″) with a noted eye for technical detail and, in the words of his son, a “tremendous command of profanity”, he quickly distinguished himself and was promoted to corporal before earning a commission as an officer in 1900. As an officer in peace time Currie was noted for his detailed inspections and his rapid transformation from “one of the boys”, into a rigid disciplinarian. This duality, an officer raised from the ranks, who could both embody the rigid tradition of the British military and who had an intimate familiarity with the life and ways of the enlisted men would become a defining feature of his career.
During Currie’s peace-time career as an officer he maintained a second career as a real-estate [agent]. After becoming head of Matson Insurance Firm 1904, he and the firm invested aggressively in the Victoria real-estate market. In 1913 Currie’s financial situation began to rapidly deteriorate as a consequence of price declines in the real-estate market. Currie’s financial problems nearly led him to refuse to stand up the 50th Regiment Gordon Highlanders of Canada in 1913. In July 1914 Curry used $10,833.34 of regimental funds intended for the purchase of uniforms and kit to pay his personal debts, and found himself facing forcible retirement just as the Canadian Army was being mobilized for war. At the intervention of one of his subordinates, Major Garnet Hughes, he instead accepted promotion as brigadier-general of the 2nd Brigade of the 1st Canadian Division, and ignored correspondence from the new commander of the 50th regiment, Major Cecil Roberts, about the missing funds until he was overseas.
Currie arrived at camp Valcartier on September 1st, 1914 to find himself charged with 10x as many men as he had ever led before, no staff, a shared tent as a command center, and the duty to prepare these men for one of the most difficult theatres of war the world has ever seen. The six months between taking command and the arrival of his brigade in the trenches near Ypres were marked by two mud besotted poorly supplied training camps, shoddy kit, rampant disease, and the company of a certain bear that was to become beloved by children around the world. Through this period Currie was well liked by the men, but known as a disciplinarian with an eye for technical detail. In March 1915 the brigade was deployed to what was expected to be a quiet part of the front with the intent of allowing the men to gain some experience with trench warfare before they were relied upon for action. Nobody anticipated what would happen next.

Published 8 Nov 2025Rommel is called to Berlin, where he’s told to wait until May and settle for Benghazi, but he rejects that plan and decides to strike sooner. In Cairo, Wavell reads ULTRA decrypts and realizes the Luftwaffe is preparing something, while admitting he has almost nothing left to hold Cyrenaica. On the ground, the Australians storm Giarabub in a sandstorm, El Agheila is snatched after a botched British ambush, and Rommel orders preparations to hit Mersa Brega before the British can dig in.

Samopal vz 38: Czechoslovakia’s Interwar Drum-Fed SMG in .380
Forgotten Weapons
Published 25 Jun 2025Military interest in a submachine gun was late in Czechoslovakia, but by the late 1930s a development program was put into place. Interestingly, the main use case for an SMG was seen as being a replacement for a rifle-caliber LMG in fortification mounts. The thought process seems to have been that a large volume of fire was the necessary element to keep invaders away from border fortresses, and the ballistic power of the fire was not so important.
The vz38 was designed by František Myška, chambered for the 9x17mm (.380) cartridge used by the vz22/24 pistol then in service. It was tested against the ZB26 light machine gun. It proved reliable and effective, and its 96-round drum magazine (copied from the Finnish Suomi) was a particularly nice element. An initial order was placed and the gun was formally adopted into service, but production never began. Instead, German occupation of the country put an end to the project and only 20 preproduction examples were ever made.
Many thanks to the VHU — the Czech Military History Institute — for giving me access to this very rare example to film for you. The Army Museum Žižkov is a part of the Institute, and they have a three-story museum full of cool exhibits open to the public in Prague. If you have a chance to visit, it’s definitely worth the time! You can find all of their details (including their aviation and armor museums) here:
QotD: Historical training is not “spending 7 years memorizing dates”
James @TTJamesG
The fact that you spent 7 years memorizing dates and the culmination of that is arguing semantics on X is depressing. Is it too late for a refund? You wrote an entire thread addressing a point I never made, a point you intentionally misconstrued.Another thing that has come up a fair bit here recently is the idea that historical training consists of “spend[ing] 7 years memorizing dates” which is a severe misunderstanding of what historians do.
It confuses the job of reading history books for the job of writing them.
While any historian is going to end up knowing a lot of names and dates simply as a byproduct of teaching and working with their material, raw memorization is not a significant part of the PhD training process.
Instead, the focus is on research skills and analysis.
In practice, we can divide a lot of historical training into three components: the historical method, “theory”, and then field-specific training.
The historical method is the process and heuristics we use to assess historical sources.
While history students work from history books that are “pre-chewed” as it were, historians work with their evidence in its raw, unprocessed form: archives of documents, ancient texts, inscriptions, memoirs, archaeological remains and so on.
The historical method is how we approach that raw material: who produced it? What information would they have had (eyewitness? second hand?), what sources might they have had? What might their own aims have been?
And how can we most plausibly fill in gaps in our evidence?
Then there is historical theory. No good historian is a doctrinaire follower of a single theory of history — rather these are toolboxes of ideas we use to frame the research questions we’re asking.
But to use those ideas, you must know and understand them first.
So “critical theory” is interested in power relationships, while an Annales framework is interested in long-term structures and cultural assumptions, while a materialist framework focuses on material conditions and so on.
Each would imply different questions of the evidence.
Part of the point of learning theory, of course, is that each theory lens is, in and of itself, incomplete. Cultural structures matter, individual choices matter, material conditions matter, etc. etc.
You learn and think about a bunch of these to know the blindspots of each.
Finally, historians are going to learn a bunch of research skills specific to our period and place. For ancient Roman history, that’s Latin, Greek, epigraphy, paleography, some philology and a lot of archaeology.
For a more modern field, archive research methods are huge.
On top of that, you’re also going to develop knowledge in other disciplines — sciences, social sciences — that touch on your topic of interest. I work on the costs of warfare, so military science and theory, along with economics and a bit of demographics, matter to me.
What the historian is actually doing is taking that skillset to the raw evidence of the past — sometimes asking new questions of old material, frequently asking old questions of material no one has studied intensively before — to discover new information about the past.
Of course we also assemble a broad knowledge of the societies we study (like how Roman citizenship works), which we’d need to understand our sources and our evidence.
Roman citizenship, for instance, matters a lot for understanding the Roman army!
That broad knowledge is what we’re drawing on in teaching and for that we are relying on the work of our colleagues in the discipline: each historian is doing their own original discovering-the-past work, but also keeping up-to-date on our colleagues’ work.
The end result is both a steadily improving understanding of the past but also the ability, as our own conditions and interests change, to ask new questions, rather than simply endlessly rehash old questions and old (potentially flawed) answers.

The Boomers didn’t do it, but they could have reversed it
On the social media site formerly known as Twitter, John Carter takes the entire Baby Boom generation out to the woodshed for a well-deserved talking-to:
toking-the-abacus @_toking
It’s amazing how catastrophically bad the current job market is in the US. No one wants to train anyone. They want 5-10 years experience in skills that you don’t get unless someone mentors you in a more junior role. Then you have rampant visa abuse.
Boomers mostly got paid to get trained on the job for their jobs.
Then they turned around and demanded college for everything. At a steep markup.
Then they rugpulled all the college grads by hiring foreigners to do the jobs people went into debt learning how to do.
Whole lotta incensed geriatrics in the replies saying “That wasn’t boomers, that was Griggs v Duke Power! Those judges were silent generation!”
Yes. And that was 1970. 55 years ago.
That’s kind of the point.
You were the largest generation in history, boomers. You could have reversed that insane decision. You could have ended the crazy practice of disparate impact. You could have ended the systemic bigotry of affirmative action, which discriminated not only against you, but against your own sons and, now, your grandsons. You could have used your institutional and electoral power to block DEI.
You could have done a lot of things.
But you didn’t.
At most you grumbled some, but not too loudly, because after all dad fought in the big war and you didn’t want to do a Hitler. A lot of you supported all of it wholeheartedly, because John Lennon had an imagination and MLK had a dream and remember Woodstock, man. Some of you profited from it handsomely. As a generation, as a group, whether by action or inaction, you entrenched it in every aspect of law and institutional culture.
You participated, each in your own way, in redesigning our entire society around women’s feelings, black self esteem, and sabotaging the minds, bodies, spirits, and lives of your white sons.
Don’t run from your part in this.
I’m not saying this to be mean.
I’m saying this because we fucking need you.
We need your votes, because as a direct result of the immigration policies of the last half century – which, again, yes, have their origin with Greatest and Silents, but whose most severe consequences unfolded on YOUR watch – we are absolutely, 100% screwed if we don’t deport an absolutely incredible, historically unprecedented number of people in a very short period of time. If that doesn’t happen it’s game over for America and, frankly, Western civilization. For now, for as long as you’re still breathing and capable of casting a ballot, whites are a bare majority. When you’re gone we’re outnumbered, the third world swallows the first, and it’s over.
We need you to confront the consequences of your actions and your complacency, to really feel what its done to your descendants, and to be filled with rage at the way you were misled by evil and selfish men, and an implacable determination to spend what remains to you of your lives doing whatever you can to reverse enough of the damage you allowed to be done to salvage something from this crumbling wreck of a society.
That is why we bully you.
Because we need you to see.

Lines of Fire: Operation Market Garden Part 1 of 2 – WW2 in Animated Maps
TimeGhost Cartographic
Published 5 Nov, 2025September, 1944. Soviet forces push ever westwards, slicing their way through Poland en route to Berlin. In the west, the Allies have made great strides after the invasion of Normandy, but now face a winter of relative stagnation as supply issues threaten to undercut their momentum. At this time, British Field Marshal Bernard Montgomery believes has a plan to carve a corridor through occupied Netherlands and get his forces into Germany within days, striking at the heart of the German war economy, and maybe, just maybe, ending this war before 1945 dawns. In Part 1 of 2, we look over the plan, the forces involved, and the colossal effort required to make Monty’s vision a reality.

Galand de Guerre Model 1872: Too Good for the Military
Forgotten Weapons
Published 23 Jun 2025Charles François Galand is best known for his simultaneous-extraction Model 1868, but he also developed a very good solid-frame revolver. This was specifically for the French 1871 military trials, which specifically required a solid frame. The Galand was chambered for 12mm Galand (with its distinctive very thick rim), held 6 rounds, operated in either single or double action, required no tools to disassemble, and had very simple but durable lockwork. The gun was very good, and was a very tight competitor for the other trials finalist, the Chamelot-Delvigne. Ultimately, it lost out because it was the more expensive of the two options.
For more information on the Model 1873 Chamelot-Delvigne that won the French trials, I suggest the C&Rsenal video on that model:

QotD: The Reformation
It’s easy to get lost in this stuff — I had a long bit about Cardinal Wolsey, Thomas Cromwell, the Supplication Against the Ordinaries, the Annates Bill, and so on here — but the upshot is, pulling the Church down in England revealed the massive scale of its corruption. I want to say that the Annates Bill alone doubled the King’s revenue, and the dissolution of the monasteries (well underway in Cardinal Wolsey’s time, incidentally) unlocked unimaginable wealth. But it also fatally undermined the regime, because now an attack on the existing Church structure was also an attack on the King … and vice versa.
What you got, in short, was a total social conflagration. The “Reformation” wasn’t really about theology. Nothing Luther said was particularly new. Jan Huss and John Wyclif said basically the same things 100 years earlier; hell, St. Augustine said them 1000 years before. There’s still an irreconcilable “Protestant” strain in Catholicism now — Cornelius Jansen was just a Catholic Luther, and in a lot of ways a much better one; he was declared a heretic because reasons, and “because reasons” was good enough in Jansen’s time (the very nastiest phase of the Thirty Years’ War), but since he’s just quoting St. Augustine …
The point is, the undeniable rottenness of the Catholic Church made it a convenient whipping boy for any conceivable beef against society as a whole. Because it wasn’t just the Church that was too decadent, depraved, and corrupt to go on — it was the entirety of Late Medieval society. Again, stop me if this sounds familiar, but Late Medieval society looks a lot like spoiled, histrionic children playing dress up. They look like kings, and they act like kings (popes, bishops, etc.), but it’s obvious it’s just an act — they know they’re supposed to do these things (put on tournaments, hold jubilees, preach sermons, fight wars, etc.) but they have no idea why.

Sir Arthur Currie, Canada’s best general in WW1
On the social media site formerly known as Twitter, InfantryDort gives a lesson in Canadian military history that your kids are unlikely to ever get in school:
Canada: Let us remind you of what your nation was once capable of, and likely still is again. Time will tell. Courtesy of @grok UNHINGED👇
SIR ARTHUR CURRIE: The Ontario slide-rule psychopath who turned war into a goddamn spreadsheet and made the Kaiser cry uncle.
Listen up, you trench-foot tourists and armchair Haigs. While Europe’s aristocrats were using human meat to plug shell holes, some lanky insurance salesman from Napperton, Ontario rolled up with a protractor and a grudge against inefficiency so pure it could sterilize a field hospital. Six-foot-four of quiet Canadian fury. No Sandhurst polish. No inherited estate. Just a militia gunner who looked at the Western Front and said: “This is sloppy. Let me fix your murder math.”
Vimy Ridge: the ridge that laughed at French corpses for two years. Currie hands every platoon leader a map accurate to the latrine, rehearses the assault until the boys can do it blindfolded in a thunderstorm, then unleashes a creeping barrage so precise it’s basically a Roomba made of high explosives. Four days later the ridge is theirs. France needed therapy. Canada needed a birth certificate.
Hill 70: supposed to be a sideshow. Currie turned it into a German obituary — 9,000 Canadian casualties for 20,000 German ones. That’s not a battle, that’s a hostile takeover with extra steps.
Passchendaele: Haig wants it. Currie says, “Fine, but it’ll cost exactly 16,000 of my boys”. Mud eats them like clockwork. Sixteen thousand. He predicted it to the body. The man could forecast death better than the Farmer’s Almanac predicts frost.
Amiens: the day the German army discovered existential dread. Currie’s corps punches twenty-two kilometers through the Hindenburg Line in four days like it’s made of wet cardboard. Ludendorff calls it “the black day of the German Army” and probably wet his monocle.
The Hundred Days: wherever the Canadians go, the war ends faster — Arras, Cambrai, Canal du Nord. German prisoners start asking for Currie by name like he’s the Grim Reaper’s polite cousin. “Wenn Currie kommt, bricht die Linie.” When Currie shows up, your defense budget becomes a suggestion.
And the best part? He’s not screaming. He’s not posing for propaganda photos with a riding crop. He’s in the back, recalculating artillery tables while lesser generals are still figuring out which end of the horse goes forward.
Post-war? Becomes principal of McGill because apparently breaking the German army wasn’t challenging enough. Gets slandered for “wasting lives” at Mons, sues the bastard for libel, and wins with the same cold precision he used to win battles. Even his lawsuits had kill ratios.
Runner-ups:
Sir Richard Turner — the human participation ribbon. Managed the 2nd Division like success was contagious.Sir David Watson — followed Currie’s plans like IKEA instructions: mostly right, but slower.
Sir Henry Burstall — thought “supporting fire” meant “hope the shell lands somewhere in Europe”.
Currie carried their divisions like a Sherpa with a PhD in applied violence.
Verdict: Currie didn’t just win battles. He invented the modern battlefield while everyone else was still playing medieval siege with extra mustard gas. Montgomery called him “the best corps commander of the war”, and Monty would rather die than compliment anyone.
Share this if you’d let Currie balance your checkbook, plan your wedding, and end your existential crisis with a well-timed barrage. Canada’s greatest general was a nerd with a death wish for waste and a heart that bled maple syrup for every lost soul. Never forget.
The Bear Who Beat the Nazis | Wojtek
The Rest Is History
Published 29 Jun 2025The story of Wojtek — the bear who took on the Nazis — amidst the death and devastation of the Second World War, and more specifically Poland’s heroic resistance, is a flicker of redemption amidst an otherwise deeply depressing period of history. His is a life that exemplifies not only Poland’s struggle in microcosm, but also the global nature of the war overall. Discovered by a young boy as a tiny cub, his mother dead, he was sold to Polish officers travelling to Palestine in the hills outside Tehran. The soldiers nursed and fed the young bear with milk from a vodka bottle, treating him like one of their own. Later, he was even purported to keep them warm at night, drink beer, delight in wrestling and showers, and both march and salute. When the Polish forces were finally deployed to Europe, “Wojtek” as he had been named, went with them; a mascot and morale booster to the men. There he was given military rank, and actively participated in the Italian campaign, carrying ammunition and artillery crates. But with death and destruction on all sides, what would be his fate?
Join Tom and Dominic as they discuss Wojtek, one of history’s most extraordinary animals, and his life in the army — an emblem of hope and resilience in the face of the horrors of the Second World War.
