Overview
My book, “Accident Prone,” explores the history of the concept of accident proneness, the idea that certain individuals are inherently more likely to have accidents. It traces the origins of the idea in early 20th-century Germany and Britain, demonstrating a fascinating example of simultaneous discovery.
Beyond its historical significance, “Accident Prone” reveals important shifts in social and technological strategies for managing risk. Early safety movements emphasized physical protections and individual education and discipline, while accident proneness offered a third way: identifying those deemed ‘accident prone’ and separating them from hazardous situations. However, by the late 20th century, this approach was largely replaced by a reliance on engineering and technological solutions designed to prevent accidents regardless of individual behavior.
“Accident Prone” also examines the concept’s implications for psychology, medicine, and public health. While initially framed in medical terms, the idea was eventually championed by psychologists, who sought to identify and test for the trait. Notably, psychiatrists never fully embraced accident proneness as a medical condition, a curious exception to the broader trend of medicalization in the modern era. This suggests limits to the authority of medical professionals and highlights the struggle over who controls knowledge and definitions of deviance.
This book is intended for a wide audience, including historians, psychologists, sociologists, engineers, and policymakers. It’s relevant to contemporary debates about risk assessment and management in technological societies, especially in fields like AI safety and autonomous systems, where understanding the interaction between humans and technology is crucial. It also contributes to ongoing discussions about human nature, equality, and the limits of social discrimination, raising questions about how we should deal with individuals whose behavior deviates from societal norms.
My central argument is that the rise and fall of accident proneness reveals a fundamental shift in how we approach safety in the modern world, moving from attempts to control individual behavior to engineering safer environments for everyone. This shift has significant consequences for how we design and interact with technology and raises questions about how to balance individual freedom with collective well-being in an increasingly technological society.
Finally, “Accident Prone” tells a compelling story about how our understanding of accidents has evolved over time, shedding light on the changing relationship between humans and technology in the modern era.
Book Outline
1. Introduction
I introduce the concept of accident proneness, the tendency of certain individuals to have more accidents than others. This was part of a larger strategy of improving safety in the 20th century by separating accident-prone individuals from hazardous situations, a method that decreased in use towards the end of the century as technological and engineering solutions became more widespread.
Key concept: Technology unforgivingly demands uniformity from human beings who encounter it. People encountering technology, however, differ from one another. The history that follows centers around that disjuncture.
2. Before Accident Proneness
The categorization of accidents as a societal issue developed in the 19th century alongside industrialization and mass transportation, along with the development of insurance companies to assist those affected. Before accident proneness, carelessness and clumsiness were seen as the causes of accidents.
Key concept: Clumsy people were often considered to be so by nature, as distinct from those who chose to deviate from care-ful, dutiful behavior or those who failed morally otherwise, for instance by making themselves clumsy by drinking.
3. German Origins
German psychologist Karl Marbe noted that some individuals seemed to experience accidents more often than others, just like some students experienced more injuries or illnesses. This concept of accident proneness developed from Marbe’s earlier work on linguistic errors, informed by his philosophical belief in behavioral consistency in similar circumstances, a principle he applied to accident statistics.
Key concept: Marbe viewed statistical grouping in terms of his philosophic belief that, in nature, similarities occur and tend to group together.
4. British Origins
In Britain, Major Greenwood and his assistant Hilda M. Woods researched industrial accidents, finding that a limited number of individuals experienced a disproportionate share of workplace accidents. This research into individual differences paralleled the interest in individual error developing in the science of psychology and provided support for separating accident-prone individuals from hazardous tasks.
Key concept: British publications on accidents did attract attention from industri-alists and those interested in safety.
5. Preparing the Way: Transport Operators
The practice of testing individuals for certain jobs developed among transportation companies concerned about efficiency, where managers and psychologists collaborated to test drivers for their ability to reduce accidents and economize resource use. This testing, initially to measure quantifiable traits such as reaction time, expanded to include psychological characteristics and behavioral patterns, preparing the way for testing drivers and workers for accident proneness.
Key concept: The negative task of eliminating unfit or dangerous transit and trans-port operators therefore became a major project of managers in advanced economies.
6. Consolidation and Development, 1930s-World War II
Throughout the 1920s and up to WWII, accident proneness entered more fully into public consciousness through scientific literature, industry publications, and popular sources like magazines. The idea faced a challenge in terms of its implementation - whether to identify accident proneness before it manifested in accidents or to focus on treatment and prevention after an individual was already identified as accident prone.
Key concept: Experts refined the idea and then raised doubts about it.
7. How Psychiatrists Did Not Adopt and Medicalize Accident Proneness
Despite the concurrent trend of medicalization in other areas, accident proneness was not adopted by mainstream psychiatry. While psychiatrists might have seen accident proneness as a symptom of underlying conditions, their focus was on general mental health rather than isolated tendencies. Psychologists, on the other hand, saw accident proneness as a behavioral condition they could assess and manage through testing.
Key concept: The case of accident proneness, then, stands as an exceptional nega-tive instance in which psychiatrists did not extend their professional and cultural authority over an area of human difficulty.
8. The Mid-Twentieth-Century High Point
The concept of accident proneness reached a peak in the mid-20th century, particularly in the years following WWII, with thousands of research articles published on the topic. The heightened interest was driven by rising accident rates, particularly in traffic, and the development of advanced psychological tests aimed at identifying accident-prone individuals.
Key concept: The war indeed provided a major opportunity for advocates of the idea of accident proneness to gain hearers among officials and the mem-bers of the public who were concerned about wartime productivity.
9. Eclipse of the Idea Among Experts
The decline of accident proneness as a mainstream idea began in the mid-20th century with statistical criticism challenging fundamental assumptions and questioning the predictive value of tests. The shift towards cognitive psychology and systems thinking offered alternative frameworks for understanding accidents, focusing on systemic errors rather than individual traits.
Key concept: The stages in the experts’ retreat from accident proneness represented a common, if not usual, sequence in changes in thinking in any expert community when thinkers are shifting from or abandoning an idea.
10. Bypassing Accident Proneness with Engineering
With waning faith in accident proneness as a useful predictive concept, focus shifted to engineering solutions in the latter half of the 20th century. This change, driven by the availability of resources and a growing belief in the power of technology, led to emphasis on designing systems that minimize the likelihood of errors and designing technological fixes to mitigate the damage when accidents do occur.
Key concept: The engineering approach to safety problems that ultimately rendered the idea of accident proneness largely irrelevant was, as must now be obvi-ous, not new.
Essential Questions
1. How and why did the concept of ‘accident proneness’ originate?
Accident proneness, the tendency of certain individuals to have more accidents than others, arose from a convergence of factors: the industrial revolution, statistical data collection, and evolving psychological theories. Its origins lie in early 20th-century Germany and Britain, where researchers independently noticed patterns of repeated accidents in some individuals. This simultaneous discovery highlights the cultural and intellectual climate that made the idea both conceivable and significant. Early researchers sought to find the “human factor” in accidents, a quest that led them to classify individuals based on their accident records. This classification, however, faced criticism and refinement over time, eventually giving way to more complex models that incorporated social and environmental factors.
2. How did the understanding of ‘accident proneness’ evolve over time, and what challenges did this understanding face?
Initially, accident proneness was seen as a relatively stable personality trait that could be identified and measured through psychological tests. This approach offered a seemingly straightforward way to improve safety by removing “accident prone” individuals from hazardous jobs or environments. However, over time, the validity and practicality of these tests were challenged. Statistical analyses questioned the very existence of accident proneness as a distinct trait, suggesting that chance and environmental factors played a larger role. Furthermore, the ethical implications of labeling individuals as accident prone, especially concerning employment and insurance, raised concerns about fairness and discrimination.
3. How does the history of ‘accident proneness’ reflect broader changes in societal approaches to safety and risk management?
The rise and fall of accident proneness mirrors broader shifts in societal approaches to safety. The early 20th century saw a focus on individual responsibility for accidents, with efforts to educate and discipline workers to behave safely. Accident proneness fit within this paradigm by identifying individuals deemed inherently more likely to have accidents. However, as technology advanced, a shift occurred towards engineering solutions designed to minimize human error and protect everyone, regardless of individual proclivities. This shift reflects changing social priorities, a growing faith in technology, and concerns about fairness and individual rights in an increasingly complex world.

Key Takeaways
1. The shift towards engineering solutions emphasizes building safer systems, not “fixing” individuals.
The shift from accident proneness to engineering solutions represents a fundamental change in how we approach safety. Instead of focusing on fixing the “human factor”, engineers sought to design systems and technologies that minimized the impact of human variability and error. This approach is not about blaming individuals but rather recognizing that errors are inevitable and designing systems that are resilient to them.
Practical Application:
In product design, the principle of designing for error tolerance can be applied by creating interfaces that are intuitive and easy to use, minimizing the chance of user error. For example, designing a clear and consistent layout for buttons and controls on a machine can reduce the likelihood of accidental activation or misoperation.
2. Statistical analyses alone are insufficient for understanding and predicting accident proneness.
Early attempts to identify and predict accident proneness relied heavily on statistical analysis of accident records. However, these methods faced significant challenges due to the complexity of accidents, limitations in data collection, and the transient nature of accident proneness itself. Statistical analyses can identify patterns and correlations, but they do not fully explain the complex interplay of factors that contribute to accidents.
Practical Application:
Understanding the limitations of statistical approaches can guide efforts in AI safety research. For example, when developing safety mechanisms for autonomous vehicles, focusing solely on aggregate accident statistics may not be sufficient. In-depth analysis of individual accident scenarios, including the role of AI algorithms, is crucial for identifying and mitigating specific risks.
3. Accident proneness is often a transient condition, not a fixed trait, and requires individualized approaches.
While accident proneness was initially conceived as a stable trait, research revealed that it was often a transient condition influenced by various factors, including situational stress and psychological dynamics. This shift in understanding led to a more nuanced approach that emphasized treating each individual’s accident history as a unique case, rather than classifying individuals into broad categories of accident proneness.
Practical Application:
In developing AI-powered medical diagnosis tools, it’s crucial to consider the whole patient, not just isolated symptoms or statistical probabilities. This means integrating clinical expertise, patient history, and individual circumstances into the AI’s diagnostic process to ensure more accurate and relevant recommendations.

Comparative Analysis
Compared to other works on accidents and industrial safety, “Accident Prone” offers a unique perspective by focusing on the history of the idea itself. Unlike purely statistical or epidemiological studies, Burnham’s work delves into the cultural and intellectual context in which the concept emerged and declined. It complements works like Mark Aldrich’s “Safety First,” which focuses on the building of American work safety, and Jamie L. Bronstein’s “Caught in the Machinery,” which examines workplace accidents in 19th-century Britain. While these books provide valuable historical context, “Accident Prone” goes further by analyzing how the idea of accident proneness itself shaped social strategies for managing risk.
Reflection
Burnham’s “Accident Prone” provides a valuable historical analysis of a complex concept, raising important questions about our approach to safety and the role of technology in modern life. While the book focuses on the 20th century, its insights are highly relevant to the 21st, particularly as we grapple with the increasing integration of AI and automation into various aspects of life. The shift towards engineering solutions described in the book mirrors current trends in AI safety, where the emphasis is on designing robust and reliable systems, rather than trying to predict and control individual human behavior. However, the book also raises ethical questions about social discrimination, especially in the context of using AI for risk assessment and decision-making. While engineering solutions may be more effective in preventing accidents, they also carry the risk of reinforcing existing social biases and inequalities. A skeptical angle might question the book’s emphasis on a simple binary between “individual behavior” and “engineering solutions.” Safety is often a complex interplay of factors, and effective solutions may require a combination of approaches. Nevertheless, Burnham’s analysis provides a valuable framework for understanding how our thinking about accidents has changed and the implications of those changes for our technological future.
