Omschrijving

In the 1920s and 30s, criminal interrogations were brutal, imprecise, and frequently yielded false confessions. Enter Leonarde Keeler, an eccentric, obsessive criminologist who believed that the human body was incapable of lying, even if the mouth was. His invention, the modern polygraph machine, promised to eradicate deception forever by mechanically measuring blood pressure, sweat, and respiration.

However, Keeler's noble quest quickly spiraled into a corporate obsession. He aggressively marketed the lie detector to police departments, banks, and paranoid corporations, effectively creating a multi-million-dollar industry built on physiological surveillance. As innocent people were occasionally condemned by nervous sweat and guilty psychopaths learned how to beat the machine, the polygraph sparked a century-long ethical war over the intersection of biology, anxiety, and the American justice system.

This thrilling true-crime history unearths the origins of forensic psychology. It explores high-profile 1930s murder cases, the intense rivalry between early forensic pioneers, and the terrifying reality of trusting a machine to decipher the human soul.

The body keeps the score, but the machine can misread it. The Polygraph Pioneer is a captivating look at the flawed, brilliant invention that forever changed criminal justice.
