What is a memory worth when it was manufactured by the room you sat in? In 1783, an English court rejected a confession because it came in "so questionable a shape" that no credit ought to be given to it. The judges recognized a profound truth: the worth of evidence depends entirely on how it was produced-a fact that becomes entirely invisible once the final product is sitting in a legal record.So Questionable a Shape collects four complete and unabridged books by Cornelis van Houte into a single authoritative volume: Memory in 100 Facts: Explores the organ itself-revealing how memory is not a recording, but a reconstruction assembled at retrieval, susceptible to the misinformation effect and false implantation.The Witness in 150 Facts: Argues why "unreliable" is the wrong word for eyewitness evidence, detailing how certainty is manufactured and why safeguards fail.The Confession in 150 Facts: Traces the history of testimony against oneself, from trial by ordeal and judicial torture to modern interrogation rooms where false confessions corrupt everything downstream.The Lie Detector in 100 Facts: Examines the polygraph-the only device built to determine truth-and demonstrates how it measures arousal rather than deception, acting as a mechanism to manufacture false statements.Through 500 meticulous facts, this omnibus uncovers how our legal and cognitive systems rely on instruments that produce convincing, stable readings while completely hiding the procedures used to manufacture them. Whether you are fascinated by forensic psychology, criminal justice reform, cognitive science, or true crime, this collection offers a rigorous, eye-opening examination of human fallibility and the search for truth. Cornelis van Houte, doctor of laws.
