Part 3 Introduction Summary: “Why Good People Turn Bad”

Bregman probes the perplexing question of why good people turn bad. He reflects on his past work that uncritically presented theories like Philip Zimbardo’s Stanford Prison Experiment, which proposed that evil resides in all humans, waiting for an opportunity to emerge. Bregman examines the latest evidence, much of which debunks many long-held beliefs about human nature. The author posits that many dark chapters in human history might be due to a “mismatch”—a clash between evolutionary predispositions and the modern world. While humans have evolved mechanisms for kindness, these same mechanisms have the potential to turn people cruel, especially in the face of societal constructs that are incompatible with human nature. Bregman sets the stage for exploring, in subsequent chapters, the reasons behind human cruelty and the possibility of a more harmonious society based on a realistic understanding of humanity.

Part 3, Chapter 10 Summary: “How Empathy Blinds”

During World War II, the social scientist Morris Janowitz embarked on a quest to decode what motivated Nazi soldiers. Contrary to prevailing views that ideological fervor was the driving force, Janowitz found that a sense of camaraderie or Kameradschaft was a more potent motivator. Studies involving wiretaps and interviews with POWs lent weight to Janowitz’s argument, revealing that a sense of community, rather than ideology, played a crucial role in bonding soldiers.

However, this idea of community is not limited to warfare. In Yale’s Infant Cognition Center, also known as the “Baby Lab,” studies revealed that infants exhibit a rudimentary sense of morality from an early age, choosing “good” characters over “bad” ones in puppet shows. Yet this same study also exposed an inherent tribalism in human nature, as infants displayed a tendency to choose puppets like them, regardless of moral implications. This duality is further examined in the work of Felix Warneken, who found that toddlers display genuine helpfulness toward others, even as other studies indicate that children form innate group identities based on superficial differences like shirt color.

The chapter takes a darker turn in examining the findings of psychologist Paul Bloom, who cautions that empathy can be dangerously myopic. This issue emerged in an experiment featuring a fictional sick child named Sheri Summers. Participants were more likely to favor Sheri over others when prompted to empathize, showcasing how empathy can lead to morally dubious decisions. Bloom argues that empathy often narrows the focus to immediate emotional connections, rendering people less forgiving to those considered outsiders.

Bregman also explores the military’s use of empathy for contrasting purposes: from dehumanizing the enemy to fostering effective fighting units. Military training manipulates empathy to create emotionally detached warriors capable of extreme acts of violence yet bound by a sense of brotherhood to their comrades. The chapter makes use of various case studies, interviews, and research reports to fortify its arguments, leading to unsettling questions about the dual nature of empathy. Far from being an unadulterated virtue, empathy emerges as a complex force that can both unite and divide, enable compassion as well as foment violence.

Part 3, Chapter 11 Summary: “How Power Corrupts”

Beginning with Niccolò Machiavelli’s timeless treatise The Prince, the chapter explores Machiavelli’s belief that achieving power requires a ruthless, unprincipled approach. This Machiavellian blueprint has an enduring influence, appearing as a thematic undertone in cultural landmarks such as The Godfather and Game of Thrones.

Contrary to Machiavelli’s conception, modern research spearheaded by Professor Dacher Keltner posits that power is more often achieved through “survival of the friendliest”—that is, those who exhibit empathy and kindness tend to ascend leadership hierarchies. However, Keltner’s studies reveal a dark caveat: Once in power, individuals display tendencies toward selfishness and disregard for others, a phenomenon he illustrates through the “Cookie Monster study” and other behavioral experiments. This “power paradox” is a central theme of the chapter, which posits that although power is gained through virtuous traits, it often corrupts those who come to hold it.

The book integrates biological perspectives by referencing primates like chimpanzees and bonobos, creatures that share 99% of their DNA with humans. The competitive, hierarchical nature of chimpanzee communities and the egalitarian structure of bonobo societies serve as biological allegories for human power dynamics. In contrast to Machiavellian ethos, Bregman implies that humans are innately more like bonobos, geared toward fairness and empathy.

Historically, human societies leaned toward bonobo-like traits, selecting leaders for their bravery, wisdom, and humility. However, as civilizations expanded, myths and narratives began to legitimize and maintain power structures. From the divine rights of kings to the myths of modern meritocracy, these narratives act as the glue that holds societies together. Simultaneously, though, these narratives perpetuate inequality and distort innate human tendencies.

Drawing upon anthropological evidence from tribes like the Aché and the Hadza, as well as archaeological finds like Göbekli Tepe, the chapter argues that human societies have always been large, complex networks held together by shared myths. While these myths were initially flexible, their rigidity increased as centralized power structures, such as armies, emerged. These power constructs also employed the latent threat of violence to maintain obedience, a principle still operating subtly even in contemporary democratic societies.

The chapter synthesizes these multifaceted arguments to expose a central tension: the very traits that elevate individuals to power positions are those most likely to be eroded once power is achieved. In part, this effect is due to the reinforcing effect of societal myths and the omnipresent threat of coercion. The chapter argues, in short, that while human nature may not be inherently corrupt, the systems and myths humans have erected around power certainly have a corruptive influence.

Part 3, Chapter 12 Summary: “What the Enlightenment Got Wrong”

Bregman shows how Enlightenment philosophy has had an enduring impact on modern civilization. Bregman initially reinvokes the London Blitz to demonstrate how crises often bring out communal and altruistic impulses, rather than just the survivalist, selfish behaviors Enlightenment thinkers posited as inherent to human nature. The aim in this chapter is therefore to question the foundational ideas that have shaped societal structures, including governance and economics.

Bregman traces the dichotomous nature of humanity—both constructive and destructive—back to the shift from hunter-gatherer societies to settled civilizations. In the latter, hierarchies and property complicated the social fabric. These new civilizations were the arenas in which darker aspects of human nature often played out, manipulated by social constructs, scarcity, and power dynamics that foment division and violence.

To challenge Enlightenment doctrines, Bregman presents a nuanced thesis that counters the philosophies of Thomas Hobbes and Adam Smith. These two thinkers believe that rational systems of law, democracy, and capitalism can channel human self-interest into collective benefits. In contrast, Bregman argues that this perspective oversimplifies complex human motivations. Employing historical case studies, social psychology research, and philosophical inquiry, Bregman illustrates that Enlightenment thinkers may have led society astray by founding modern institutions on overly cynical assumptions about human nature. Such institutions, driven by a distorted view of humanity, often foster the exact behaviors they assume to be inherent—selfishness, greed, and divisiveness.

The chapter contends that the Enlightenment, with its belief in rationalism and logic, was laudable for its advances in health, wealth, and social harmony; however, it also yielded a darker legacy of racism, rampant capitalism, and misuse of power. Philosophers like David Hume and Adam Smith acknowledged the altruistic and empathetic aspects of humanity; nonetheless, they also built systems predicated on pessimistic views of human nature. As a result, a self-fulfilling cycle of cynicism has influenced modern policies, affecting economies and political landscapes globally.

Bregman concludes by opening the door to an essential question: Could new institutions, based on a more balanced understanding of human nature, create a better society? The chapter serves as a pivotal junction, beckoning the reader to imagine an alternative path where institutions are designed not to exploit humanity’s worst impulses, but to elevate its best.

Part 3 Analysis

Bregman weaves the theme of the Innate Goodness of Humans into discussions ranging from human empathy to the underpinnings of power structures. Whether examining Morris Janowitz’s findings about Nazi soldiers motivated by camaraderie or analyzing the Infant Cognition Center’s discoveries about infants’ rudimentary moral choices, Bregman consistently suggests that humans, at their core, are predisposed toward community and ethical conduct. He dissects conventional wisdom that presumes a “default” status of human malevolence and replaces it with empirical examples that advocate for an essential human kindness. This analysis avoids the risk of presenting a one-dimensional picture. Bregman adds layers of complexity, cautioning against the myopia of empathy, as elucidated by psychologist Paul Bloom. Such insights indicate that innate goodness is not an unmitigated asset but is subject to distortion by other factors.

One of these factors stems from the theme of The Importance and Prevalence of Cooperation. Bregman emphasizes how cooperation, which is often mistaken for a derivative of ideological indoctrination, is an ingrained human trait. Whether the context is war or civilian life, humans are more prone to bond over shared experiences and common goals than divisive ideologies. The nuanced role of empathy, both as a facilitator for intimate connections and as a potential instigator for exclusion and violence, highlights the double-edged nature of cooperation. In instances ranging from military training to childhood development, Bregman shows that cooperation can serve both constructive and destructive ends. This paradox makes the theme not merely a confirmation of human goodness but a lens through which the complexity of human goodness can be better understood.

The final significant theme, The Impact of Societal Structures on Human Behavior, emerges most prominently in the exploration of power dynamics. Contrasting Machiavellian principles with modern sociological and psychological studies, Bregman proposes that societal norms and narratives deeply influence individual behavior. In comparing the competitive nature of chimpanzees with the egalitarian ethos of bonobos, he ties the discourse back to how societal constructs can either suppress or enhance innate human traits. In this sense, much of the book serves as a critique of how Enlightenment-era assumptions have been institutionalized, effectively shaping systems that perpetuate divisive or competitive behaviors erroneously considered “natural.”

In exploring these themes, Bregman employs several rhetorical strategies to bolster his arguments. His extensive use of case studies adds empirical weight to his thesis, grounding abstract debates about human nature with points backed by data. His cross-disciplinary approach, borrowing from anthropology, psychology, philosophy, and history, addresses the question of human nature from multifaceted angles. Bregman’s choice of diverse examples—from Nazi soldiers and Yale’s Baby Lab to Machiavelli and bonobos—keeps the reader engaged as he gradually builds layers of nuance around his straightforward thesis.

These chapters offer more depth to Bregman’s assessment of human nature, encouraging appreciation of complexity. The narrative doesn’t just celebrate humanity’s better angels. Bregman acknowledges the species’ paradoxical nature—both cooperative and destructive. Through his array of rhetorical techniques, Bregman continues to use his critique as a platform for an invitation. Namely, in urging readers to reconsider long-held assumptions, Bregman also prompts readers to envisage a society built on a more balanced, empirically substantiated understanding of what makes people fundamentally human.
