How Humans Judge Machines

Book by by Cesar A. Hidalgo, Diana Orghiain, Jordi Albo Canals, Filipa De Almeida and Natalia Martin.
Published by MIT Press.
256 pages.

How people judge humans and machines in scenarios involving labor displacement, algorithmic bias, policing, privacy violations, natural disasters, and more.

How would you feel about losing your job to a machine? How about a tsunami alert system that fails? Would you react differently to acts of discrimination depending on whether they were carried out by a machine or by a human? What about public surveillance?

How Humans Judge Machines compares people’s reactions to actions performed by humans and machines. Using data collected in dozens of experiments, this book reveals the biases that permeate human-machine interactions.

Are there conditions in which we judge machines unfairly? Is our judgment of machines affected by the moral dimensions of a scenario? Is our judgment of machine correlated with demographic factors such as education or gender?

César Hidalgo and colleagues use hard science to take on these pressing technological questions. Using randomized experiments, they create revealing counterfactuals and build statistical models to explain how people judge artificial intelligence and whether they do it fairly. Through original research, How Humans Judge Machines bring us one step closer to understanding the ethical consequences of AI.

Table of Contents

  • Executive Summary — A short summary of the main findings.
  • Chapter 0: Introduction — Why should we worry about the way in which people judge machines? Together with chapter 1, the introduction motivates the study and puts the experiments in the context of some of the relevant literature.
  • Chapter 1: The Ethics of Artificial Minds — This chapter introduces basic concepts used throughout the book: moral status and agency, intent, and the moral dimension of the moral foundations theory of social psychology. This chapter also introduces the basic experimental technique used in subsequent chapters.
  • Chapter 2: Unpacking the Ethics of AI — This chapter explores scenarios involving emergency decisions with uncertain outcomes, algorithmic creativity, self-driving cars, and patriotism. It provides the first examples of people judging humans and machines differently, exhibiting both bias in favor and against machines.
  • Chapter 3: Judged by Machines (Algorithmic Bias) — This chapter presents experiments related to algorithmic bias in human resources, university admissions, and police scenarios. This chapter also discusses basic ideas about fairness and theoretical work attempting on the mathematical foundations of fairer algorithms.
  • Chapter 4: In the Eye of the Machine (Privacy) — This chapter explores experiments related to privacy using scenarios involving camera systems and personal data. This chapter also discusses basic concepts in privacy, such as anonymity and privacy preserving data collection methods.
  • Chapter 5: Working Machines (Labor Displacement) — This chapter compares people’s reactions to labor displacement attribute to technology and humans. It also discusses recent literature on labor displacement, automation, and labor precarization.
  • Chapter 6: Moral Functions — This chapter uses statistics to model the behavior observed across experiments to uncover general principles governing differences in the way people judge humans and machines. It also explores the average effects of demographics (e.g. education, gender) in people’s judgments of humans and machines.
  • Chapter 7: Liable Machines — This chapter concludes by connecting the work presented before with ideas from science fiction, mathematics, and law.
  • Appendix and Additional Scenarios — The statistical appendix contains additional details about the data collection methodology plus dozens of new scenarios which were not discussed in the main text of the book.
