Robert N. Spengler III's "Nature's Greatest Success"

Robert N. Spengler III directs the Fruits of Eurasia: Domestication and Dispersal research project and leads the Domestication and Anthropogenic Evolution Research Group at the Max Planck Institute of Geoanthropology in Jena, Germany. He is author of the book Fruit from the Sands and has published dozens of scholarly articles while running research projects across Central Asia.

Spengler applied the "Page 99 Test" to his new book, Nature's Greatest Success: How Plants Evolved to Exploit Humanity, with the following results:

The ninety ninth page of Nature’s Greatest Success is bisected by two different and equally captivating topics; the page opens with the conclusion of a discussion of strawberry domestication. The popular narrative of strawberry domestication involves a farmer in the 1700s – a bit of a strawberry fanatic – who planted different species of strawberries in his garden, only to notice one day that something rather different was growing in his strawberry patch. I ask whether the process of stumbling across hybrid forms of a crop can be thought of as a proxy for some aspects of domestication in prehistory. If an ancient farmer suddenly discovered a unique form of a crop growing in their field, would they have tried to reproduce it, and, if so, which of the forms of plants in your produce market are a result of this process? The latter part of the page dives into the odd case of quinoa domestication, and I rationalize the ways that the process could not have involved human intentionality. In short, genetic features of the plant prevent active seed selection from fostering the process of domestication.

I believe that a reader picking the book up and thumbing to the page in question would gather enough of an understanding of the overall book that, if the topic catches their attention, they will return to page one and begin reading. The book spans a wide range of topics, using many case studies, with the goal of providing the reader with an idea of what domestication looked like in antiquity and how the foods they eat came into being.

Domestication remains one of the most captivating topics of scholarship across the sciences, as it is a key part of the story of what permitted humanity to become culturally modern. Without domesticated crops, you would not have any of the material goods that you take for granted, human populations would be low, cities could not exist, and the arts and sciences would not have developed. Geneticists, archaeologists, and ecologists have started to realize that humans in prehistory did not intentionally domesticate crops. This means that the evolutionary process that permitted human cultural development was a happy accident, as opposed to a great achievement of humanity. In Nature’s Greatest Success, I explore these new ideas about how domestication traits first evolved. In this book, I encourage the reader to think in different ways about ancient agriculture and the ongoing domestication processes all around you today. In short, the most important questions about humanity have remained unanswered because of long-standing misunderstandings about how ancient domestication occurred, and the true story of domestication is far more interesting than the long-standing narrative.

Steve L. Monroe's "Mirages of Reform"

Steve L. Monroe is an Assistant Professor of Political Science at the National University of Singapore. He is a scholar of development, with a primary focus on the Arab world. His scholarship examines two of the region's most pressing developmental challenges: limited economic integration, and gender inequality.

Monroe applied the “Page 99 Test” to his new book, Mirages of Reform: The Politics of Elite Protectionism in the Arab World, and shared the following:

Page 99 defends how this chapter in Mirages of Reform measures the strength of Jordanian industries’ social connections to the state. This measure relies on data from publicly traded firms. It gauges industries’ social-connections strength as the share of chairmen and board members (CBMs) of publicly traded firms in an industry who belong to Jordan’s historically favored ancestral group – Jordanians of East Bank descent.

The first half of page 99 presents the pros and cons of this measure. On the plus side, data from publicly traded firms is publicly available. This helps me identify socially connected CBMs based on whether they have an “East Bank” last name, and cull information on their firms’ size and profits. On the downside, this measure assumes that industries without publicly traded firms have weak social connections to the state.

The second half of page 99 tries to validate this assumption. Compared to industries with publicly traded firms, Jordanian industries without publicly traded firms have on average smaller firms, lower tariffs and are devoid of State-Owned Enterprises (SOEs) – all signs of weak social connections. I then argue that if industries without publicly traded firms did in fact have strong social connections to the state, this measure would be a “hard” test of the argument as it would overestimate the social connections strength of weakly connected industries; differences in tariff cuts and profits between industries with strong and weak social connections would be even greater if I had a more accurate measure of industries’ social connections. Page 99’s last paragraph presents qualitative evidence from different industries that substantiates the chapter’s measure of social-connections strength.

The Page 99 Test on Mirages of Reform passes in spirit but not in substance. Page 99 gives the browser a whiff of the book’s essence – its challenges, assumptions, methodological orientations. Defining and measuring social connections was one of the hardest parts of this book project. Page 99 exhibits one of the book’s tactics in measuring social connections. I like how the page begins by acknowledging this measure’s limitations, then segues into an empirical and theoretical defense of the measure, before validating the measure with secondary sources and case expertise. I hope that a browser reading page 99 would infer that I understand the empirical challenges of studying state – society relations, and have made a good faith effort to overcome these challenges.

Nevertheless, page 99 does not reveal the book’s argument: industries with stronger social connections undergo more extensive but deceptive levels of trade policy reform when their state has greater support from the US and the EU. The Page 99 Test also excises the previous chapters’ lengthy explanation and definition of social-connections strength. I conceptualize the strength of industrialists’ social connections to the state as a function of the quality and frequency of their interactions with state officials. By this logic, the economic elite who belong to politically favored social groups have the strongest social connections to their regime – hence page 99’s focus on CBMs of East Bank descent. This information is key to assessing the social connections measure’s validity.

Lastly, in shrinking Mirages of Reform’s measure of social connections to CBMs from politically favored groups, the Page 99 Test excludes the multiple approaches this book uses to assess social connections across time and place. Instead, the page 99 reader might mistakenly conclude that this book restricts its measures of social connections to what is static and quantifiable. For a more complete yet condensed understanding of Mirages of Reform, I encourage the causal browser to skim the introduction.

Marcus Alexander Gadson's "Sedition"

Marcus Alexander Gadson is Assistant Professor of Law at the University of North Carolina School of Law and the author of articles published in places such as the UCLA Law Review and the Georgetown Law Journal.

Gadson applied the “Page 99 Test” to his new book, Sedition: How America's Constitutional Order Emerged from Violent Crisis, and reported the following:

Page 99 of Sedition says:

…virulent white supremacy political campaign in American history to shatter the movement for interracial political cooperation. Meanwhile, Democrats in Wilmington conspired to overthrow a government they associated with Black political power, which culminated in an armed mob demanding the mayor’s resignation at gunpoint after a day of bloodletting. If both these efforts succeeded, white supremacists could end Black political involvement in the state and eradicate the spirit of 1868 once and for all.

Someone reading this would get an inkling of what my book is about, but miss important context and not truly understand the argument I make. They would know that they will eventually read a chapter explaining that white supremacy motivated some North Carolinians to overthrow Wilmington’s government and that their insurrection was violent. However, they would not know, just from the excerpt, that the book makes a larger claim: that constitutional crises have been common in American history and have shaped American constitutional law and history in dramatic ways. The Wilmington Insurrection of 1898 is part of that larger story I tell.

Sedition provides six examples of constitutional crisis in American history, most of which readers will never have heard of, such as the Buckshot War, Dorr Rebellion, and Brooks-Baxter War. And by “constitutional crisis,” I mean things like terrorist organizations overthrowing duly elected governments and militias loyal to rival candidates shooting each other dead in the street. I then explain how these crises have affected the drafting and interpretation of both state and federal constitutions. At a time when many commentators are arguing about whether we are in a constitutional crisis, I believe this book can give readers vital context as they assess the debates.

Adam S. Hayes's "Irrational Together"

Adam S. Hayes is professor of sociology at the University of Lucerne. Before entering academia, he worked as an options market maker and equity derivatives sales trader and was licensed as a financial advisor.

Hayes applied the "Page 99 Test" to his new book, Irrational Together: The Social Forces That Invisibly Shape Our Economic Behavior, with the following results:

Page 99 is the hinge where the book moves from storytelling to method. It really distills the broader mission of the book: to show that economic choices are never purely about numbers or cognitive quirks—they’re also greatly influenced by social forces. The passage invites readers to see how experimental techniques can unpick the ways that price, convenience, and status jostle with trust, loyalty, and shared identity in everyday financial decisions. It’s not about dismissing “economic” explanations or romanticizing the social. Instead, the page makes a case for measuring these factors in tandem. Unraveling the way that our dollars interact with our culture, social contexts, socialization processes, and relationships is indeed a miniature of the book’s central framework.

Does the Page 99 Test work?

Absolutely. The entire argument of Irrational Together is that economic life is governed, in part, by social forces—and that we can measure these influences. Page 99 reveals how the book bridges disciplines, bringing sociology’s insights about things like norms, networks, and identity into conversations typically dominated by economic rationality or behavioral biases. It’s not a rejection of what's come before, but an insistence that to truly understand choice, we have to see how these perspectives mesh and rub up against each other. This page signals a book that’s more than just a critique of “rational economic man”; it’s a toolkit for better understanding how our choices get entangled with who we are, who we know, and what matters most to us.

If this page draws you in, the rest of Irrational Together offers an extended invitation to see economic life in high relief. From meme-stock booms to the hidden scripts of gendered money talk, from algorithmic investing to the moral boundaries of peer-to-peer transactions, the book uses familiar stories, original data, and lived experiences to explore how everything from culture and social identities to interpersonal ties and social networks shape even what we think of as our most private economic decisions. What emerges is a vision of economic life that is less about solitary individuals optimizing abstract curves or even hopelessly irrational beings with limited processing power & cognitive biases--and more about real people navigating the social landscape that is the economy. By the end, readers won’t just have a richer view of economic sociology; they’ll see how these insights can inform more reasonable efforts at navigating financial choices and the crafting of more effective policies. If page 99 made you curious about why you sometimes pay more to buy from a friend—or why an app can nudge you toward “rational” investing—you’ll find the rest of the book picks up that thread and runs with it.

Neil Gregor's "The Symphony Concert in Nazi Germany"

Neil Gregor is professor of modern European history and director of the Parkes Institute at the University of Southampton. He is the author of Daimler-Benz in the Third Reich, How to Read Hitler, and Haunted City: Nuremberg and the Nazi Past. Most recently he coedited Dreams of Germany: Musical Imaginaries from the Concert Hall to the Dance Floor.

Gregor applied the “Page 99 Test” to his new book, The Symphony Concert in Nazi Germany, and shared the following:

Page 99 of my book falls in a section entitled ‘Guidance, Direction, Censorship’, so takes us straight to the heart of what the book is about – namely the question of how the Nazi dictatorship impacted the work of German orchestras in the 1930s and 1940s. As one would only expect, the regime swiftly developed mechanisms to ensure that orchestras adjusted their repertoire to Nazi demands regarding the promotion of ‘healthy’ German music (whatever that was). Conversely, the regime’s antisemitism was such that the performance of ‘Jewish music’ was rigorously policed – composers such as Mahler or Mendelssohn disappeared from concert programmes very quickly. So in this sense the Page 99 Test works remarkably well!

At the same time, the passage nods to the ways in which the work of monitoring orchestral programming was carried out not by ‘the Nazi regime’ in the sense of something suspended over the musicians’ own world, but by figures co-opted from that musical world into the apparatus of control. In other words, it carries something of one of the core arguments of the book, namely that the remaking of German musical life under the dictatorship was a process in which musicians participated actively themselves. Over the course of the last twenty years historians of Nazi Germany have come to understand that the regime was not so much something that sat on top of German society as something that was embedded in it. This encourages us to think of musicians – and others – not merely as passive objects of the regime’s policies, but as agents in the formulation and implementation of those policies, and to recognise that the participatory dimensions of Nazi rule were in operation in the musical sphere too.

Where the test works slightly less well is in capturing the side of the book that is about audiences. As well as exploring how orchestras changed as institutions, the book is concerned with the question of whether new forms of listening to music emerged among the public. I am interested to explore not only how the transformation of ‘Germans’ into ‘Nazis’ over the 1930s and 1940s can be mapped in the concert hall, but also to think about how the concert hall was a site in which that transformation was pursued. In that way, the book moves beyond thinking about the world of policy and regulation into offering a social and cultural history of the phenomenon of concert-going more generally.

Sarah Gabbott & Jan Zalasiewicz's "Discarded"

Sarah Gabbott is a Professor of Palaeobiology at the University of Leicester. She researches the fossil record of ancient life and is particularly interested in understanding how fossils form and what they reveal about evolution and ecology. She actively seeks new fossil specimens from across the globe, going on digs to China, South Africa and the Canadian Rockies. She also works in the laboratory analyzing fossils and undertaking grisly experiments to determine how decomposition affects fossilization. Recently, she has turned her attention to the potential fossil record created by human activity, especially thinking about how long our 'artefacts' will endure.

Jan Zalasiewicz is Emeritus Professor of Palaeobiology at the University of Leicester. He was formerly a field geologist and palaeontologist with the British Geological Survey, involved in the geological mapping of eastern England and central Wales. His interests include Early Palaeozoic fossils, notably the graptolites (a kind of extinct zooplankton), mud and mudrocks, the Quaternary Ice Ages, the nature of geological time, and the geology made by humans. In recent years he has helped develop the concept of an Anthropocene epoch. He has written many popular science articles and books.

Gabbott and Zalasiewicz applied the “Page 99 Test” to their new book, Discarded: How Technofossils Will be Our Ultimate Legacy, and reported the following:

Page 99 of our book Discarded takes the reader, fair and square, into the kind of world – or rather worlds – that we as palaeontologists must navigate in our daily work. It casually spans three and a half billion years, as the story stretches out from the microbes that colonize our clothes today to the first microbes that began to grow on the seafloors of the early Earth. It crosses, too, from living world to the chemical one, as it considers which minerals might crystallize to turn this kind of interaction into tangible, durable fossils, whether of primordial microbial colonies or of our modern fashion items. And it’s also a page that takes us into the mechanisms that keep our planet habitable, in introducing the diatoms, oceanic microplankton that provide much of the oxygen that we breathe.

It's a fair sample, we think, of the story that we have to tell: of how our science of palaeontology can throw a new kind of light on many aspects both of our lives and of the workings of our planet, as we show how even our most fleeting of human fashions may become immortal, leaving fossil impressions in strata that can endure until the end of the Earth.

This single page, mind, gives only a tantalizing glimpse of the extraordinary novelty and diversity of technofossils: those objects that we create for our profit and pleasure, and that have durability built into them by human design as a very effective first step to future fossilization. You have to turn to other pages of our book to consider the palaeontological puzzles posed by objects that range from concrete- built megacities spanning thousands of square kilometres to the almost unbelievably minuscule patterns etched onto the microchip within your computer and mobile phone; and, to consider how this new kind of palaeontology is affected by such things as global warming, sea level rise, and the balance between war and peace.

It’s the whole narrative of the book that shows our motive for writing it: that the countless objects that we so casually discard won’t simply somehow go away, but will all too often persist as a challenging, polluting legacy for our and future human generations. As technofossils begin their long journey to geological posterity, looking at them through a palaeontologist’s eyes may help with the vexing problems that they pose today.

Ross Benes's "1999"

Ross Benes is a journalist, market research analyst, and author. His writing has appeared in Esquire, The Wall Street Journal, Smithsonian Magazine, and Entertainment Weekly. As an entertainment industry analyst, he’s regularly cited as an expert source by the Los Angeles Times, NPR, and Bloomberg. His books include Rural Rebellion: How Nebraska Became a Republican Stronghold and Turned On: A Mind-Blowing Investigation into How Sex Has Shaped Our World.

Benes applied the "Page 99 Test" to his new book, 1999: The Year Low Culture Conquered America and Kickstarted Our Bizarre Times, with the following results:

The 99th page of 1999 covers how Vince McMahon spun untrue stories about WWE’s primary competitors. One passage states:

Because WWE bought out its competition, it owns their video libraries, which WWE uses for documentaries and series about the companies McMahon purchased. These videos can be a fun trip down memory lane with their fantastic archival footage and interviews with prominent sources. But there’s bias because WWE spins stories so it always appears superior.

Readers seeing this page would get a good sense of what that particular chapter is about. But they wouldn’t get a sense of how 90s low culture connects to our modern world. Later on in that chapter I tie WWE’s revisionism to insincere storytelling by current politicians and business leaders. One of those pages, combined with page 99, would provide a strong example of what the book is about. Because 1999 is a group of essays, no single page covers its multiple subjects. But out of the subjects covered in the book, pro wrestling is arguably influencing the world the most. In that regard, page 99 points readers in the right direction of connecting yesterday’s low culture to current events.

Deborah Mutnick's "No Race, No Country"

Deborah Mutnick is professor of English at Long Island University.

She applied the “Page 99 Test” to her new book, No Race, No Country: The Politics and Poetics of Richard Wright, and shared the following:

I love Ford Madox Ford’s theory of opening a book to page ninety-nine to find the quality of the whole revealed. Of course, I had no idea what would be on page 99 of my recently published book until I looked. Ford is right, at least about No Race, No Country: The Politics and Poetics of Richard Wright, except that I have to start with the sentence on page 98, which continues onto 99: “As he recounts in Black Boy, he stayed up all night to read issues of the New Masses after his first visit to the John Reed Club in 1933 and woke up to write ‘I Have Seen Black Hands,’ expressing the core principle in interracial, working-class solidarity that would guide him throughout his life, even when he chafed against it.” I then cite this stanza from the poem:

I am black and I have seen black hands
Raised in fists of revolt, side by side with the white fists of white workers.
And some day—and it is only this which sustains me—
Some day there shall be millions and millions of them,
On some red day in a burst of fists on a new horizon!

Then comes a section break with the subtitle, “The Marxist Threads of Wright’s Sociology,” in which I contest the idea that Wright appropriated the sociological perspective of the Chicago school of urban sociology, according to literary scholar Carla Cappetti, thus attesting to the “1930s dying movement” of US Communism (40). To the contrary, not only did sociology during the Cold War fall into line with US policy to equate communism with totalitarianism and fascism, a perspective Wright explored and ultimately rejected in his 1953 novel The Outsider, but also the resurgence of Marxist sociology in the 1960s countered that narrative with a critique that he would have shared. For Wright, who remained a Marxist for the rest of his life, the Chicago school of sociology offered useful tools of inquiry, but as was always the case with him, he approached them critically, taking what he needed to pursue his own quest for a more just, egalitarian world.

Judith Weisenfeld's "Black Religion in the Madhouse"

Judith Weisenfeld is Agate Brown and George L. Collord Professor in the Department of Religion at Princeton University. Her books include New World A-Coming: Black Religion and Racial Identity during the Great Migration, winner of the 2017 Albert J. Raboteau Prize for the Best Book in Africana Religions.

Weisenfeld applied the “Page 99 Test” to her new book, Black Religion in the Madhouse: Race and Psychiatry in Slavery's Wake, and reported the following:

Page 99 of Black Religion in the Madhouse describes the transition in the diagnostic categories for mental illness in early twentieth-century US psychiatry from mania and melancholy to dementia praecox and manic-depressive psychosis, the latter categories proposed by German psychiatrist Emil Kraepelin. To illustrate the change, I present the case of Charles D., an African American laborer who was admitted to St. Elisabeths Hospital in Washington DC in 1905, diagnosed with acute insanity caused by “religious excitement,” discharged from the hospital and readmitted the same year. On readmission, he was diagnosed as suffering from dementia praecox. While the application of these diagnostic categories was not limited to African Americans, Charles’s case underscores the book’s argument about the prominence of “religious excitement” as a listed cause of insanity for African American patients in the late-nineteenth and early-twentieth centuries and signals the incorporation of these ideas into the new disease categories, even as the language of “religious excitement” fades away.

On page 99 I write:

As white American psychiatrists embraced Kraepelin’s new disease category in the early twentieth century, they mobilized ideas about race and religion in diagnosing Black patients and used their clinical experiences to theorize more generally about race, religion, and mental illness in ways that linked discourses from the older diagnostic system to the new.

The Page 99 Test works well for my book as it describes a critical turning point in the history of race, religion, and American psychiatry with the adoption of Kraepelin’s system. I argue that, with the turn from long-standing ideas among white American psychiatrists about “racial traits” to a system they presented as more rigorously scientific, sedimented assumptions about Black people’s propensity for superstition and religious excess persisted. In fact, in the early twentieth-century studies white psychiatrists published exploring the incidence of dementia praecox among Black patients, they often highlighted “primitive” religious expression as a helpful diagnostic tool.

At the end of page 99, I note that Emil Kraepelin read work by white American psychiatrists on dementia praecox among African Americans and took their accounts of racialized mental instability as authoritative. While not a central part of the book’s argument, it points to the influence of white physicians’ ideas about African American religion and mental normalcy in psychiatric circles.

Jordan Thomas's "When It All Burns"

Jordan Thomas is an anthropologist and former Los Padres hotshot wildland firefighter. His work has appeared in the Los Angeles Times, the San Francisco Chronicle, The Seattle Times, and The Drift. Thomas is a Marshall Scholar with graduate degrees from the University of Cambridge and Durham University. He is currently a Chancellor’s Fellow at the University of California.

Thomas applied the "Page 99 Test" to his new book, When It All Burns: Fighting Fire in a Transformed World, with the following results:

From page 99:

“And so we waited, hoping for an initial attack. An initial attack, or IA, is the zenith of fire suppression operations, allowing us to be the first crew on the fire’s edge. “That’s what hotshot’s live for,” Scheer told me.

Then, just when an initial attack seemed a distant dream, when the routine of running and practicing and pranking had softened my nerves, and when it seemed inevitable that we would sulk home as faux heroes— just then, we heard a noise. It started in a high pitch before dropping in frequency, zapping us all like an electric shock coming from the radio in Aoki’s truck. A voice followed the sound, announcing a lighting fire in the Apache-Sitgreaves National Forests. Within thirty seconds, we were gone.

* ** *

The American West is full of pyrophiles, or fire lovers— species of plants, animals, and fungi whose existence depends upon their ability to follow ignitions. Of these species, the fire beetle is perhaps the most tenacious. These beetles are black, the size of a fingernail, and are equipped with heat receptors the width of a human hair. Their receptors hold liquid that expands when absorbing radiant heat, allowing the beetles to detect flames from over one hundred miles away. Wildfires act like magnets, pulling the beetles in swarms of millions, where they mate amid the flames, waxy bellies dispelling heat as they bore into charred wood to lay their eggs. In California in the 1940s, football games were occasionally disrupted when the collective embers of spectators’ cigarettes attracted beetles that, finding—"

If readers open to page 99, they’ll get a strong sense of the book’s overall approach. I move between close-up scenes of life on a hotshot crew—its rhythms, language, tensions, and jokes—and wider reflections on fire as an ecological and political force. That pairing is at the heart of the book: the human experience of wildfire nested inside the broader systems that create and respond to it. And I like to slip in cool facts and details—like fire beetles drawn to flames from over a hundred miles away. This, of course, is a metaphor for what we were doing as wildland firefighters who had traveled some 800 miles to be present in the Southwest when the monsoons brought lightning fires. The difference was, we followed the cycle of fire in order to break it.

As the fire season progresses and the fires grow more dangerous and difficult, the interplay between lived experience and broader context deepens. The book sinks into the historical forces and power structures that have made 21st-century fire so violent—centuries of suppression policy, colonial land management, and extractive economic systems. At the same time, I keep the story grounded in my crew and our lives on the fireline, where humor, banter, and friendship coexist with exhaustion, stress, and absurdity. That balance is the rhythm of the book, just as it was the rhythm of the fire season.
