Clearer Than Truth
The Polygraph and the American Cold War
John Philipp Baesler
University of Massachusetts Press, 2018
A person strapped to a polygraph machine. Nervous eyes, sweaty brow, the needle trembling up and down. Few images are more evocative of Cold War paranoia.

In this first comprehensive history of the polygraph as a tool and symbol of American Cold War policies, John Philipp Baesler tells the story of a technology with weak scientific credentials that was nevertheless celebrated as a device that could expose both internal and external enemies. Considered the go-to technology to test agents' and employees' loyalty, the polygraph's true power was to expose deep ideological and political fault lines. While advocates praised it as America's hard-nosed yet fair answer to communist brainwashing, critics claimed that its use undermined the very values of justice, equality, and the presumption of innocence for which the nation stood.

Clearer Than Truth demonstrates that what began as quick-fix technology promising a precise test of honesty and allegiance eventually came to embody tensions in American Cold War culture between security and freedom, concerns that reach deep into the present day.

The Lying Brain
Lie Detection in Science and Science Fiction
Melissa M. Littlefield
University of Michigan Press, 2011

"The Lying Brain is a study to take seriously. Its argument is timely, clear, and of particular importance to the enlargement of our understanding of the relationships among science studies, literary studies, and technology studies."
---Ronald Schleifer, University of Oklahoma

Real and imagined machines, including mental microscopes, thought translators, and polygraphs, have long promised to detect deception in human beings. Now, via fMRI and EEG, neuroscientists seem to have found what scientists, lawyers, and law enforcement officials have sought for over a century: foolproof lie detection. But are these new lie detection technologies any different from their predecessors? The Lying Brain is the first book to explore the cultural history of an array of lie detection technologies: their ideological assumptions, the scientific and fictional literatures that create and market them, and the literacies required for their interpretation.

By examining a rich archive of materials about lie detection---from science to science fiction---The Lying Brain demonstrates the interconnections of science, literature, and popular culture in the development and dissemination of deception detection in the American cultural imagination. As Melissa Littlefield demonstrates, neuroscience is not building a more accurate lie detector; it is simply recycling centuries-old ideologies about deception and its detection.

The Truth Machines
Policing, Violence, and Scientific Interrogations in India
Jinee Lokaneeta
University of Michigan Press, 2020
Using case studies and the results of extensive fieldwork, this book considers the nature of state power and legal violence in liberal democracies by focusing on the interaction between law, science, and policing in India. The postcolonial Indian police have often been accused of using torture in both routine and exceptional criminal cases, but they, and forensic psychologists, have claimed that lie detectors, brain scans, and narcoanalysis (the use of “truth serum,” Sodium Pentothal) represent a paradigm shift away from physical torture; most state high courts in India have upheld this rationale.

The Truth Machines examines the emergence and use of these three scientific techniques to analyze two primary themes. First, the book questions whether existing theoretical frameworks for understanding state power and legal violence are adequate to explain constant innovations of the state. Second, it explores the workings of law, science, and policing in the everyday context to generate a theory of state power and legal violence, challenging the monolithic frameworks about this relationship, based on a study of both state and non-state actors.

Jinee Lokaneeta argues that the attempt to replace physical torture with truth machines in India fails because it relies on a confessional paradigm that is contiguous with torture. Her work also provides insights into a police institution that is founded and refounded in its everyday interactions between state and non-state actors. Theorizing a concept of Contingent State, this book demonstrates the disaggregated, and decentered nature of state power and legal violence, creating possible sites of critique and intervention.
