Guns, Germs, and Steel: The Fates of Human Societies

Why Read This

Jared Diamond answers why world history developed so differently across continents by tracing 13,000 years of history to reveal that the answer lies in geography.

In November 1532, 168 Spanish soldiers under Francisco Pizarro captured the Inca emperor Atahuallpa, who was guarded by 80,000 troops. Within minutes, thousands of Inca warriors lay dead while the Spanish suffered no casualties. This was the most dramatic moment in the history of European conquest. The deeper question runs the other way: why did it happen in this direction, and never the reverse?

Diamond argues that differences in geographic and biogeographic environments determined different historical trajectories on each continent. Eurasia had the greatest geographic luck: a long east-west axis, the most suitable wild plants and animals for domestication, and climate zones that enabled rapid spread of innovations. These advantages accumulated over thousands of years into guns, germs, steel, writing, technology, and complex political organization.

What makes Diamond's argument so powerful is that he overturns racist assumptions with empirical evidence. We often assume that technological differences reflect differences in intelligence, when evidence shows the opposite: technologically "primitive" societies likely experienced fiercer natural selection for intelligence than modern industrial societies. New Guineans whom Diamond knew over 33 years were on average more intelligent, more alert, and more capable of forming mental maps than Westerners.

This book teaches us that history flows from accumulated geographic advantages amplified over thousands of years, with individual genius and cultural superiority playing only a marginal role. This is an essential lesson for understanding the modern world, still shaped by inequalities rooted in geography.

Key Points

1. Yali's question opens the mystery of global inequality - In 1972, Yali, a Papua New Guinea politician, asked Diamond: "Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?" This simple question opened a 13,000-year investigation of human history to discover that the answer lies in geography. Biological or intelligence differences between races play no role.

2. Food production is the ultimate cause of conquest - One hectare of land can feed 10-100 times more farmers than hunter-gatherers. This numerical advantage was the beginning of many other advantages: dense populations, food surplus, specialization, metal weapons, epidemic diseases, writing, technology, and complex political organization.

3. The Anna Karenina Principle explains why only 14 of 148 large mammals were successfully domesticated - "Animals that can be domesticated are all alike; every animal that cannot be domesticated is undomesticable in its own way." Of 148 species of candidate large terrestrial herbivorous mammals worldwide, only 14 were successfully domesticated before the 20th century, and 13 of them came from Eurasia. This highly uneven distribution is one of the most important geographic asymmetries in history.

4. Continental axis determines the speed of innovation spread - Eurasia has a long east-west axis, enabling rapid spread of domesticated plants and animals across the same climate zones from Portugal to Japan. The Americas and Africa have north-south axes, hindering spread due to drastic climate changes. Wheat spread 5,500 miles west (to England) in 5,500 years, while corn spread a few hundred miles from Mexico to the US in 3,000 years.

5. Germs killed more people than swords - Up to 95% of Native Americans were killed by Eurasian diseases like smallpox, measles, and flu. Swords and guns played a far smaller role. These crowd diseases evolved from Eurasian domestic animals. The Americas had only 5 domestic animals, none living in large herds, so they did not develop equivalent epidemic diseases.

6. Cumulative advantage is the most powerful force in history - Eurasia had a 6,000-year head start in domestication over eastern North America (8500 BC vs 2500 BC). A 1% advantage sustained over 10,000 years is more powerful than a 100% advantage sustained for 10 years. By the time Europeans arrived in the Americas in 1492, Eurasia had 6,000 years of accumulated advantage in technology, political organization, and disease immunity.

7. Invisible asymmetries determine visible outcomes - Invisible differences like continental axis orientation and available wild animal species had highly visible consequences: who conquered whom. We often focus on outcomes without understanding the invisible causes that determined them.

8. Empirical evidence rejects racist explanations - There is no evidence that Eurasians are more intelligent. On the contrary, New Guineans may be genetically superior in mental ability due to fiercer natural selection (death from violence and starvation vs death from disease in Eurasia). Diamond spent 33 years in Papua New Guinea and observed that New Guineans were on average more intelligent, more alert, and more capable of forming mental maps than Westerners.

Yali's Question: The Origin of Global Inequality

In 1972, Yali, a Papua New Guinea politician, asked Diamond: "Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?"

This simple question opened the greatest mystery of history: why did global inequality form the way it did?

Equal Starting Lines

Diamond expanded Yali's question into a broader contrast. In 1500 AD, before European colonial expansion began, societies on different continents were already vastly different in technology and political organization:

• Eurasia: States with metal tools, writing, and approaching industrialization
• The Americas: Two societies (Aztec and Inca) had kingdoms with stone tools
• Most of the rest of the world: Still living as hunter-gatherers or tribal farmers

By 11,000 BC, all continents were already inhabited by modern humans, yet all societies were still hunter-gatherers. Relatively equal starting lines. The different levels of development from 11,000 BC to 1500 AD produced the technological and political inequality.

Rejecting Wrong Explanations

Diamond rejects three popular but wrong explanations:

1. Racist explanation (biological differences):

There is no evidence that Eurasians are more intelligent. On the contrary, New Guineans may be genetically superior in mental ability due to fiercer natural selection. In Papua New Guinea, the main causes of death were violence, starvation, and accidents, forcing selection for intelligence and alertness. In Eurasia, the main cause of death was epidemic disease, which does not select based on intelligence.

Diamond spent 33 years working in Papua New Guinea and observed that New Guineans were on average more intelligent, more alert, and more capable of forming mental maps than Westerners.

2. Cold climate stimulates innovation theory:

Northern Europe contributed nothing fundamental until the last 1,000 years. The most advanced civilization in the New World (Maya) was in tropical Yucatan and Guatemala. This argument is clearly inconsistent with the facts.

3. River valley creates civilization theory:

Archaeological studies show that complex irrigation systems did not emerge until after political centralization, not the other way around. Irrigation was a consequence of organized states, not their cause.

The Right Answer: Geography

Yali's question forces us to confront hidden assumptions about race and culture. Most people privately still accept racist explanations, even if they don't say so publicly. Without a convincing alternative explanation, hidden suspicions that biological explanations might be true will persist.

Diamond provides a comprehensive alternative explanation: history followed different courses because of differences in environments. Biological differences play no role.

This is also an urgent moral argument. The moral gap in history must be filled with an evidence-based ultimate explanation.

Key insight: "History followed different courses for different peoples because of differences among peoples' environments, not because of biological differences among peoples themselves."

From Food Production to Conquest

Food production (agriculture and animal husbandry) is the ultimate cause that led to all the proximate causes of conquest: dense populations, food surplus, specialization, metal weapons, epidemic diseases, writing, technology, and complex political organization.

Fundamental Numerical Advantage

The causal chain begins with a simple fact: one hectare of land can feed 10-100 times more farmers than hunter-gatherers.

This is because by selecting and growing edible species, we transform 0.1% of wild biomass into 90% edible biomass.

This numerical advantage was the beginning of many other advantages:

1. Large domestic animals provide four additional ways to feed more people:

• Meat
• Milk (doubling lifetime calories)
• Fertilizer to increase crop yields
• Plow power to open new land

2. Sedentary lifestyle enables shorter birth intervals (2 years vs 4 years for nomadic hunter-gatherers), because mothers don't need to carry two toddlers at once.

3. Stored food surplus enables full-time specialization:

• Kings and bureaucrats who govern states
• Professional soldiers who wage constant war
• Priests who provide religious justification
• Metalsmiths who develop weapons
• Scribes who preserve information

4. Epidemic germs (smallpox, measles, flu) evolved from domestic animals, killing up to 95% of populations without immunity.

5. Horses and camels revolutionized transport and warfare, becoming the "jeeps and Sherman tanks" of ancient warfare.

Dramatic Evidence: Conquest of the Inca

A dramatic example is Pizarro's conquest of the Inca in 1532. Spain's immediate advantages were clear: steel swords vs stone clubs, armor vs thin padding, horses vs foot soldiers, firearms.

All these advantages were rooted in food production that began thousands of years earlier in Eurasia.

Even more decisive were germs. A smallpox epidemic spreading before Pizarro's arrival killed Inca emperor Huayna Capac and triggered a civil war that weakened the empire. In Mexico, smallpox killed nearly half the Aztecs including Emperor Cuitlahuac.

By 1618, Mexico's population had dropped from 20 million to 1.6 million, a 95% decline.

The Paradox of Agriculture

Most surprisingly, food production brought heavy costs. Early farmers were actually shorter, less nourished, and died younger than the hunter-gatherers they replaced. Time allocation studies show farmers often worked longer hours than hunter-gatherers.

So why did the transition happen?

The driver was an autocatalytic process: food production enabled more people, who required more food, which drove more intensive food production, which enabled even more people. People did consciously choose agriculture, though the choice followed from population dynamics.

Once started, there was no turning back.

Key insight: "By selecting and growing a few dozen species of edible plants and animals that we can eat, such that they constitute 90 percent rather than 0.1 percent of the biomass on a hectare of land, we obtain far more edible calories per hectare."

The Anna Karenina Principle in Domestication

"Animals that can be domesticated are all alike; every animal that cannot be domesticated is undomesticable in its own way."

Like happy marriages requiring success in many different aspects, animal domestication requires many different characteristics, failure in just one aspect is enough to doom domestication.

Highly Uneven Distribution

Of 148 species of candidate large terrestrial herbivorous mammals (over 100 pounds) worldwide, only 14 were successfully domesticated before the 20th century. And 13 of them came from Eurasia.

Highly uneven geographic distribution:

• Eurasia: 72 candidates, 13 domesticated (18%)
• Sub-Saharan Africa: 51 candidates, 0 domesticated (0%)
• The Americas: 24 candidates, 1 domesticated (4%)
• Australia: 1 candidate, 0 domesticated (0%)

Six Determining Factors

Six factors determine whether an animal can be domesticated:

1. Efficient diet: Carnivores require 10x more food (must feed herbivores first). Gorillas are herbivores but too selective.

2. Fast growth rate: Elephants take 15 years to mature, too expensive to raise.

3. Breeding in captivity: Cheetahs won't mate in captivity without elaborate courtship rituals. Vicuñas (llama relatives) are the same.

4. Docile temperament: Hippos kill more people in Africa than lions. Rhinos and grizzly bears are too aggressive.

5. Don't panic: Gazelles and deer jump into fences and die when frightened. Sheep and cattle are calmer.

6. Compatible social hierarchy: Animals that live in herds with dominant leaders (horses, goats, cattle) can be domesticated because humans can assume the leader role. Territorial individual animals (deer, antelope) have no concept of herd leadership.

The Zebra Case: Proof of the Anna Karenina Principle

The most surprising example is Sub-Saharan Africa with 51 candidate large mammals but none successfully domesticated. Africans did try repeatedly, and when Eurasian cattle and sheep reached Africa, they were enthusiastically adopted. The barrier lay in the animals themselves.

Zebras are the classic example of the Anna Karenina Principle. Despite looking like horses, zebras cannot be domesticated because:

• Extremely aggressive temperament and tendency to bite (even in modern zoos, zebras injure more keepers than tigers)
• Perfect lasso-dodging reflex, evolved over millions of years avoiding lions

Modern attempts to domesticate eland, elk, moose, musk ox, and American bison with advanced genetics have mostly failed. If 20th-century scientists couldn't domesticate zebras, how can we blame ancient farmers for not domesticating them?

Implications for the Americas

The Americas had only 5 domestic animals (turkey, llama, alpaca, guinea pig, Muscovy duck), none living in large herds or close to humans.

This explains why the Americas did not develop epidemic diseases like Eurasia. Crowd diseases evolved from domestic animals.

Llamas are the most surprising example of disease absence. Though llamas are domestic animals, they had four barriers:

• Kept in smaller herds
• Total numbers stayed far below Eurasian livestock
• People avoided llama milk
• Llamas remained outdoors

Contrast with Eurasia where pigs and cattle were often kept in peasant huts, enabling microbe transfer.

Key insight: "Of 148 candidate large mammals worldwide, only 14 were successfully domesticated before the 20th century, and 13 of them came from Eurasia."

Continental Axis: East-West vs North-South

Continental axis orientation determines the speed of spread of domesticated plants, animals, and technology. Eurasia has a long east-west axis, enabling rapid spread across the same climate zones. The Americas and Africa have north-south axes, hindering spread due to drastic climate changes.

The Logic of Spread

Domesticated plants and animals can only spread easily across areas with:

• Same day length
• Same seasons
• Same rainfall
• Same temperature

That is, areas at the same latitude.

Eurasia's East-West Axis

Wheat domesticated in the Fertile Crescent (Turkey) could immediately grow in Portugal or Japan because all lie at the same latitude. Sheep suitable for Syria were also suitable for Greece and India.

Domestication began around 8500 BC in the Fertile Crescent, and by 3000 BC had reached:

• England: 5,500 miles west
• China: 5,000 miles east

Speed: average 1 mile per year.

The Americas' North-South Axis

Corn domesticated in tropical Mexico couldn't immediately spread to the United States or Argentina because of large climate zone differences. Each crop had to undergo lengthy genetic selection to adapt to different summers, day lengths, and temperatures.

Corn was domesticated in Mexico around 3500 BC. It didn't reach eastern North America until 200 AD, over 3,000 years later, though only a few hundred miles away.

Llamas and alpacas domesticated in the Andes never spread to Mesoamerica or North America.

Africa's North-South Axis

Crops domesticated in the Sahel zone (sorghum, millet) couldn't spread south to equatorial Africa or southern Africa because of climate differences.

The Mediterranean climate zone of South Africa's Cape was unsuitable for equatorial crops of Bantu farmers, so Khoi pastoralists remained there without agriculture until European arrival.

6,000-Year Consequences

Continental axis is a perfect example of how geography determines the speed of innovation. The cause lies in geographic barriers, with Mesoamerica matching Eurasia in intelligence and creativity. They simply faced greater obstacles to spread.

The consequences were enormous: Eurasia had a 6,000-year head start in domestication over eastern North America (8500 BC vs 2500 BC).

By the time Europeans arrived in the Americas in 1492, Eurasia had 6,000 years of accumulated advantage in technology, political organization, and disease immunity.

Key insight: "Eurasia's major axis is oriented east-west, enabling rapid spread of domesticated plants and animals across the same climate zones from Portugal to Japan. The Americas and Africa have north-south axes, hindering spread."

Lethal Gift of Livestock: Germs as Conquerors

Humanity's deadliest killers, smallpox, measles, flu, tuberculosis, malaria, plague, cholera, are infectious diseases that evolved from domestic animal diseases.

Up to 95% of Native Americans were killed by Eurasian germs. Swords and guns played a far smaller role.

Evolution of Crowd Diseases

Crowd diseases only emerged in societies with food production and large populations. Measles requires a minimum population of 500,000 to persist. Once everyone is infected, the virus dies unless enough new susceptible babies arrive.

Evolution of disease from the microbe's perspective: our symptoms like coughing, diarrhea, and genital sores are clever evolutionary strategies by microbes to spread themselves:

• Coughing spreads flu through the air
• Diarrhea spreads cholera through water
• Genital sores spread syphilis through sex
• Skin lesions spread smallpox through contact

Why do germs evolve to kill their hosts? Death is an unintended byproduct. As long as each victim infects on average more than one new victim, bacteria will spread even if the first host dies.

Conquest of the Americas: 95% Death

The most horrifying example is the conquest of the Americas:

Mexico:

• Smallpox reached Mexico in 1520
• Killed nearly half the Aztecs including Emperor Cuitlahuac
• Survivors were demoralized by the mysterious disease that killed Indians and spared Spaniards, as if advertising Spanish invincibility

Peru:

• Smallpox arrived around 1526
• Killed Inca emperor Huayna Capac and his designated heir
• Triggered the civil war that Pizarro exploited

United States:

• Mississippian societies in the Mississippi River valley, densely populated Indian cities with sophisticated technology, disappeared even before Europeans arrived
• When Hernando de Soto marched through the southeastern US in 1540, he found abandoned city sites from epidemics that spread from coastal Indians infected by Spanish explorers

For the New World as a whole, the Indian population decline is estimated at 95% within one or two centuries after contact.

Why One-Way Exchange?

The critical question: why was the germ exchange one-way? Why were there no deadly diseases sent back from the Americas to Europe?

The answer lies in the difference in domestic animals. Eurasian crowd diseases evolved from Eurasian herd animal diseases. The Americas had only 5 domestic animals, none living in large herds:

• Turkeys and Muscovy ducks live in small flocks
• Guinea pigs may have contributed to Chagas disease, though this remains uncertain
• Llamas had four barriers: smaller herds, total numbers far below Eurasian livestock, people avoided llama milk, and llamas remained outdoors

Contrast with Eurasia where human mothers in Papua New Guinea often nursed piglets, and pigs and cattle were kept in peasant huts. This proximity enabled microbe transfer from animals to humans.

Microbes as Weapons of War

Most surprising is the scale of death. Until World War II, more war casualties died from microbes than battle wounds.

Winners of past wars were often the armies carrying the nastiest germs, with generalship and weapons mattering less than we assume.

Key insight: "95% of Native Americans were killed by Eurasian diseases, not by swords. For the New World as a whole, the Indian population decline within one or two centuries after Columbus's arrival is estimated at 95 percent."

The Causal Chain: Geography to Conquest

All the concepts in this book form a clear causal chain from geography to conquest:

1. Geography determines which wild plant and animal species were available for domestication (Anna Karenina Principle)

2. Domestication enabled food production, yielding population densities 10-100 times higher

3. High population density forced complex political organization (band → tribe → chiefdom → state)

4. Complex political organization enabled specialization: professional soldiers, metalsmiths, scribes

5. Specialization led to advanced technology (metal weapons, writing), epidemic diseases (from domestic animals), and professional armies

6. Continental axis orientation determined the speed of spread of all these innovations

7. All these factors together enabled European conquest of the Americas, Australia, Africa, and Pacific islands

Compound Interest in History

Small geographic advantages (having wild wheat and sheep vs not having them) accumulated over thousands of years into large advantages (guns, germs, steel, writing, states).

This is compound interest in action, 1% advantage per year over 10,000 years produces enormous differences.

Path Dependence

Once Eurasia gained an early lead in domestication (around 8500 BC), that advantage locked them onto a path leading to more advanced technology, disease, and political organization.

The Americas, starting domestication 6,000 years later, could never catch up.

Antifragility

Eurasian societies exposed to epidemic diseases for thousands of years became stronger (developed immunity). Isolated societies never exposed to disease remained fragile. 95% died when finally exposed.

Practical Implications

For Understanding History

This book teaches us to always ask: what are the ultimate causes behind proximate causes?

When we see conquest, push past "who won because they had better weapons" and ask "why did they have better weapons?"

For Understanding Modern Inequality

The global inequality we see today, developed vs developing nations, is largely a legacy of geographic advantages from thousands of years ago.

Developing nations can still advance. They simply started from different starting points.

For Rejecting Racist Explanations

Diamond provides powerful empirical arguments to reject racist assumptions. Historical differences arose from geographic luck. Differences in intelligence or culture played no role.

New Guineans living as tribal farmers deserve respect as sophisticated peoples. They simply lacked access to plants and animals suitable for domestication.

For Business and Innovation

The principles in this book apply to the modern world:

• Cumulative advantage: Companies that gain a small early advantage (first-mover advantage) can turn it into a large advantage if they can sustain compound growth

• Network effects: Like domestication spreading faster in Eurasia due to the east-west axis, innovation spreads faster in well-connected networks

• Path dependence: Like the QWERTY keyboard persisting despite being suboptimal, technologies adopted early often lock us into certain paths

For Personal Life

• Focus on systems over individuals: World history was determined by geographic and biological systems, with individual genius playing only a marginal role. Personal success likewise grows from systems and habits accumulated daily, far beyond bursts of momentary effort

• Compound small advantages: Small consistent advantages (1% better each day) accumulate into extraordinary results over the long term

• Understand invisible causes: Like the invisible continental axis orientation determining world history, invisible factors (mental models, habits, environment) determine our success

FAQ

Q: Does this book say that geography is the only factor determining history?

A: No. Diamond argues that geography is the most important ultimate cause, though many proximate factors (culture, politics, individual genius) also play roles. He rejects the racist explanation that biological differences determine history.

Q: Why did Eurasia have more domesticable animals than other continents?

A: Of 148 candidate large mammals worldwide, 13 of the 14 successfully domesticated came from Eurasia. This was biogeographic luck, Eurasia happened to have more species with the right characteristics for domestication (efficient diet, fast growth, docile temperament, don't panic, compatible social hierarchy).

Q: How long did it take for domestication to spread from the Fertile Crescent across all of Eurasia?

A: Domestication began around 8500 BC in the Fertile Crescent and reached England (5,500 miles west) and China (5,000 miles east) by 3000 BC, about 5,500 years, or an average of 1 mile per year.

Q: Why didn't the Americas develop epidemic diseases like Eurasia?

A: Because the Americas had only 5 domestic animals (turkey, llama, alpaca, guinea pig, Muscovy duck), none living in large herds or close to humans. Crowd diseases evolved from domestic animals living in large herds and close to humans, conditions common in Eurasia and absent in the Americas.

Q: What percentage of Native Americans were killed by Eurasian diseases?

A: An estimated 95% of Native Americans were killed by diseases like smallpox, measles, and flu within one or two centuries after first contact with Europeans. In Mexico, the population dropped from 20 million to 1.6 million by 1618.

Q: Is there evidence that New Guineans are more intelligent than Westerners?

A: Diamond spent 33 years in Papua New Guinea and observed that New Guineans were on average more intelligent, more alert, and more capable of forming mental maps than Westerners. This may be because of fiercer natural selection. In New Guinea, death came from violence and starvation (forcing selection for intelligence), while in Eurasia death came from disease (which selects on different traits).

Q: Why is an east-west continental axis more advantageous than north-south?

A: Domesticated plants and animals can only spread easily across areas with the same day length, seasons, rainfall, and temperature, that is, areas at the same latitude. An east-west axis enables rapid spread across the same climate zones, while a north-south axis requires lengthy genetic adaptation for each new climate zone.

Q: Does this book advocate geographic determinism?

A: No. Diamond advocates geographic probabilism. Geography provides different starting conditions, and what matters is how small advantages accumulate over thousands of years through compound interest and positive feedback loops.

Q: What is the biggest lesson from this book for understanding the modern world?

A: The inequality we see today, between developed and developing nations, is largely a legacy of geographic advantages from thousands of years ago. Understanding that geography determines starting conditions helps us see that with the right systems, interventions, and time, starting disadvantages can be overcome.

Critical Assessment

Strengths

1. Comprehensive and interdisciplinary empirical argument

Diamond synthesizes evidence from genetics, archaeology, biogeography, epidemiology, and linguistics to build a highly convincing argument. No other book combines so many disciplines to answer fundamental questions about history.

2. Rejects racist explanations with evidence, going beyond morality

Many people reject racist explanations for moral reasons, though they cannot provide a convincing alternative explanation. Diamond provides an evidence-based alternative: geography determines history, while biology plays no role.

3. Powerful mental framework for understanding causality

This book teaches us to always ask: what are the ultimate causes behind proximate causes? This framework applies to history, business, politics, and personal life.

4. Highly convincing evidence from Papua New Guinea

Diamond spent 33 years in Papua New Guinea and observed firsthand that New Guineans were on average more intelligent than Westerners. This is very strong ethnographic evidence that technological differences emerge from environmental conditions, with intelligence held essentially equal across populations.

Limitations

1. Too deterministic in some parts

Diamond claims geographic probabilism (not determinism), though some parts of the book feel too deterministic, as if geography completely determines history without room for human agency or historical accidents.

2. Insufficient attention to contingency and counterfactuals

The book focuses on explaining what happened, though it lacks exploration of what could have happened differently. For example, if Eurasia had lacked wild wheat, would domestication still have started elsewhere?

3. Oversimplification in some cases

The explanation of why China didn't become the inventor of industrialization (despite having technological advantage for thousands of years) feels too simple. Diamond explains with political fragmentation vs unification, though this may oversimplify a very complex process.

4. Insufficient discussion of culture and institutions

Diamond focuses on ultimate geographic causes, though he sometimes overlooks the role of proximate causes like culture and institutions. For example, why did Western Europe come to dominate the modern world ahead of the Middle East or China? Geography alone falls short of explaining this.

Conclusion

Guns, Germs, and Steel is one of the most important books for understanding the broad patterns of human history. Diamond successfully answers questions that have haunted historians for centuries with a comprehensive synthesis from many disciplines.

The enduring value of this book lies in explaining history and in providing a mental framework for understanding causality, systems, and cumulative processes. After reading this book, we never again see history, or the modern world, the same way.

Who should read this book:

• Anyone wanting to understand why the modern world formed the way it did
• Anyone wanting a mental framework for understanding causality and systems thinking
• Anyone wanting strong empirical arguments to reject racist explanations of history

Rating: 5/5 - A fundamental book that changes how we understand history and global inequality.
