The book’s unfinished work
Women’s Compounding Score
Who was allowed to compound knowledge, and who was locked out?
Fifty-four civilizations and periods, from Sumer at 2600 BCE to the present, each asked the same eight ledger questions. Could she choose her husband. Could she vote. Could she learn to read. Could she own anything. Could she enter a profession. Did anyone write down what she said or did. Did childbirth kill her. Did she control her own body.
Supports Chapter 3 and Chapter 18, “The Sneakers Strike Back; She’s Working 9 to 5, and Then Some.” Chapter 18 points here for the ledger, all of its rows; Chapter 3 points here for the maternal-mortality curve, country by country.
The ledger
Each question is scored 0 to 10, brighter for more open. The composite is the mean of the eight. The book counts fifty-four civilizations and periods; the working ledger behind it carries 56 rows, and every one of them is shown here rather than dropping two by guesswork. Scoring is for the ordinary woman’s experience, not the elite exception: one queen or one poet does not lift a row.

What the book reads from the ledger
Athens, 480 to 322 BCE
The very bottom of the ancient world: composite 1.00, against 2.50 for Sumer and 3.25 for Old Kingdom Egypt. The book says Athens taught its women nothing; the ledger scores its education question 1, the band for informal, domestic teaching only.
Joseon Korea, 1392 to 1910
The lowest standing of any period outside a declared atrocity: composite 0.75. Only the Khmer Rouge (0.25) and the two Taliban governments sit lower.
Afghanistan, 1996 to 2001
Zero on every one of the eight ledger questions: composite 0.00.
Afghanistan, 2021 to the present
The same floor with one exception, childbirth, which scores 1: fewer women die in it. Composite 0.13.
Meiji Japan, 1872
Compulsory female education. Learning to read goes from 3 under the Tokugawa to 5, and being written down from 2 to 5.
Cambodia after 1979
The book says Cambodia recovered to its pre-1975 baseline on every one of the eight questions inside two decades. The ledger row for 1979 to the present matches or passes the pre-1975 row on six of the eight; owning property (4 against 5) and control of her own body (5 against 6) sit one point below. The difference is logged for the next edition.

The flat line and the lift
Half the species held outside the protected niche by statute, custom and inheritance code for nearly the whole of the scribe’s career. The line is essentially flat for fifty centuries, then goes vertical in a hundred and fifty years (Ch 17).

China non-monotonic
Crop: rice and wheat (north wheat, south rice)
Falls before it rises. Foot-binding (roughly 960-1911) tightened during the exam system’s strongest centuries, then the 1950s Marriage Law and mass literacy campaigns opened the channel in a single generation. The score dips in the 1800s below its pre-1800 level.
Japan non-monotonic
Crop: rice
The clearest non-monotonic case. Heian women wrote the world’s first novel; terakoya schools taught girls for two centuries; Meiji opened mass female schooling in 1872, the inflection point the book marks (Figure 18), even as the 1898 Civil Code narrowed women’s legal standing. Post-war literacy was already near universal, but the credentialing class stayed male long after.
Korea non-monotonic
Crop: rice
Early Joseon women could inherit and hold property. As the gwageo dragon matured, Neo-Confucian ideology stripped those rights (Deuchler 1992). The 1961 jolt reversed it: female literacy rose from 64 percent to 97 percent in twenty years.
France non-monotonic
Crop: wheat
France’s cave overflowed in 1789: too many educated men for too few positions. The Napoleonic Code of 1804 then locked women out for another century and a half.
Soviet Union / Russia non-monotonic
Crop: wheat
The only system that deliberately lifted the mortality tax and opened the gate at once. The fastest female compounding in any scribal class, inside a dragon with no exit. When the dragon was slain in 1991 the gains scattered.
The mortality tax
Why the score barely moves before 1937. Maternal deaths per 100,000 live births in England and the UK held near one percent per delivery from the first parish registers until sulfonamides entered clinical practice. Then the cliff.
Country by country
Maternal deaths per 100,000 live births. The book’s earlier edition gave Loudon’s English rates as 750 to 1,050 in the eighteenth century, around 500 in the nineteenth, and a plateau until the mid-1930s; Sweden and Finland near 900 in 1800 and about 5 today; the United Kingdom from around 500 in 1935 to 13 by 2022. The lifetime risk for a woman fell from one in eighteen to one in 2,400, and most of the fall came after 1937.

China (Pre-1487) (-1400 to 1487 (rising) / 1487-1905 (stagnation))
Gate shut for women across entire period; exam system excluded women by design
The keju ran 1300+ years and selected exclusively for men. Women were formally excluded from the examination system. The same institutional channel that left a measurable genetic fingerprint (Ch 4) compounded ONLY through men because the gate was built with a male-only lock. Chinese foot-binding (roughly 960-1911) physically restricted women during the same centuries the dragon was strongest. The dragon and the mortality tax reinforced each other: the institution excluded women, and the biological risk of reproduction discouraged families from fighting for inclusion.
Elman 2000; Bossen & Gates 2017
Roman Republic/Empire (-200 to 200 (rising))
Julia’s death (54 BC) falls in the RISING period: the biological tax hit during peak compounding
Julia died in August 54 BC during Rome’s rising period (200 BC - 200 CE, Rising Score 3). The Republic was actively compounding: law, engineering, census, 10-15% literacy. The one-percent-per-delivery risk killed the human bond holding the political architecture together. The biological tax did not wait for stagnation. It struck at the peak.
Plutarch Life of Pompey; Loudon 2000
French Ancien Regime (1100-1604 (rising) / 1604-1789 (stagnation))
Salic Law + maternal mortality = double lock on women’s compounding
France’s Salic Law (formalized 14th c.) excluded women from inheriting landed property AND from the throne. Combined with the ~1% per delivery mortality rate that held steady from 1550-1800 (CAMPOP Cambridge), French women faced two gates: a legal one written by the scribe and a biological one written by nature. The dragon’s credentialing monopoly ran through male-only institutions (universities barred women until 1880s). The Revolution (1789) slew the dragon but did NOT lift the mortality tax: that required sulfonamides in 1937, 148 years later.
Alesina/Giuliano/Nunn 2013; Loudon 2000
Modern US University (1876-1970 (rising) / 1970-2026 (stagnation))
1982 women surpass men in enrollment: the mortality tax lifts AND the dragon weakens simultaneously
The US university system’s rising period (1876-1970) was overwhelmingly male. Women earned just 19% of bachelor’s degrees in 1900. The mortality tax was still high (US maternal mortality ~600/100k in 1915). When BOTH constraints lifted: sulfonamides/antibiotics after 1937 AND women’s legal access to universities: women surpassed men in enrollment by 1982 and have widened the gap every year since. The stagnation period (1970-present, Score 2) coincides with credential inflation: which now affects women disproportionately because they are the majority of the credentialing class. The dragon’s modern costume (UPL for law, tenure for academia) may be the first dragon in history that gates MORE women than men.

England/UK: Mortality Timeline (1550-1937 plateau / 1937-2022 cliff)
England straddles Late Medieval Europe (counter-example: the claw never closed) and the modern era
England/UK never formed a full dragon (Late Medieval Europe scores Stagnation 1, WEAK evidence). No unified credential monopoly: competing institutions (Oxford vs Cambridge vs Inns of Court vs Church vs Crown). This fragmentation is PRECISELY why England was where the mortality-tax data exists at all: parish registers from 1538 (Thomas Cromwell’s mandate) give us 470 years of continuous data. A monopoly system would not have produced competing recordkeeping institutions. The absence of the dragon enabled the innovation (sulfonamides, antibiotics, sterile surgery) that eventually lifted the biological tax. Fragmentation -> innovation -> the cliff begins 1937.

Scribal Saturation: All Professions (Crossing dates 1970s-2010s)
Women’s entry into professions COINCIDES with saturation crossing dates
Finance crossed in the early 1980s (women 9.1% of CFAs in 1990, 18% by 2023). Law crossed ~1990s (women 3% of lawyers in 1970, 38% by 2023). In the academy, women were 23% of full professors in 1993 and 34% by 2023. In EVERY case, the profession had already passed its saturation crossing date before women reached significant representation. Women are entering scribal classes that are already in the tail-eating phase: producing more ink per novel insight. The question the book asks: is this the dragon’s last costume? Women finally enter the gate just as the gate becomes the problem?

Joseon Korea (1392-1600 (rising) / 1600-1897 (stagnation))
Neo-Confucian gender restrictions tightened AS the dragon formed
Early Joseon women had property rights and could inherit. As the dragon matured (credentialing monopoly via the gwageo exam, self-serving yangban class), Neo-Confucian gender ideology was IMPOSED: women’s property rights were stripped, widows forbidden from remarrying, strict inside/outside separation enforced. The dragon and gender exclusion grew together. The exam selected for men; the ideology that justified the exam excluded women. Same pattern as China but compressed into a shorter timeline with clearer before/after evidence.

Soviet Union (1917-1960 (rising) / 1960-1991 (stagnation))
Only system that deliberately lifted the mortality tax AND opened the gate simultaneously
The USSR drove maternal mortality from ~1200/100k (1920s Russia) to ~55/100k by 1970. Simultaneously mandated women’s education and workforce participation. Women earned 58% of Soviet engineering degrees by 1985. Result: the fastest female compounding in any scribal class in history. But the dragon (state academy monopoly, no exit) ate the gains: women were compounding inside a stagnating system. When the dragon was slain (1991 collapse), the compounding scattered rather than compounded further.
