|  Investigations The facts about truth serum
 In a fascinating chapter of Mesmerized: Powers 
              of Mind in Victorian Britain (Chicago, 1998) associate professor 
              of history Alison Winter, AB’87, details how mesmerism was 
              commonly used to treat chronic illness. Originally called “animal 
              magnetism” and later “mesmerism” after its creator, 
              Franz Anton Mesmer, the practice required the mesmerist (usually 
              a man) to make “magnetic passes” over his subject (usually 
              a woman) to bend her to his will. These passes—long, sweeping 
              hand gestures over the surface of the subject’s skin—were 
              close enough that each felt the body heat of the other, without 
              actually touching. In the chapter, “Emanations from the Sickroom,” 
              well-known Victorian intellectuals—and invalids—including 
              poet Elizabeth Barrett Browning, mathematician Ada Lovelace, and 
              journalist Harriet Martineau describe mesmerism’s power. Their 
              accounts are so persuasive that a reader could be sucked into the 
              Victorian mindset, convinced—for a while, anyway—that 
              the technique had curing ability.

 |  But Mesmerized is not at all concerned 
              about whether mesmerism “worked.” Instead Winter, who 
              earned her Ph.D. at the University of Cambridge in 1993, reconstructs 
              the Victorian debate over mesmerism’s validity—a challenging 
              task, given that when she started her research she considered the 
              practice “totally ridiculous,” though as a historian 
              she suspended such judgments. Taking a similarly nonjudgmental approach to 
              her current project, Winter is exploring the notion of a “truth 
              serum” or “truth technique.” Last year she received 
              a Guggenheim fellowship to support her research, which traces the 
              science of memory from the 19th century to the present.  Her truth-sera account begins in the 1910s with 
              Robert House, an obstetrician in Ferris, Texas. Like many country 
              doctors of the time, House used scopolamine, or “twilight 
              sleep,” to ease labor pains. He claimed that his patients, 
              though seemingly incapacitated by the drug, could answer questions—and 
              always spoke the truth. The example he gave to support his claim 
              was hardly an issue worth lying about: when House asked the husband 
              where the scale was (to weigh the newborn), he didn’t know, 
              but the mother heard House and answered correctly that it was hanging 
              on a nail in the kitchen. “Maybe she actually said something 
              that was more of a revelation,” Winter speculates, “or 
              maybe she said other stuff too,” but House was too decorous 
              to include it in his account. Although truth sera have been associated with 
              hostile police interrogations since the 1930s, House publicized 
              his research for the opposite purpose: to exonerate the innocent. 
              Convinced that the justice system was deeply corrupt, he gave “scopolamine 
              interviews” to suspects protesting their innocence. Most courts 
              rejected these interviews, which presented a “neat circular 
              issue,” Winter explains. For the truth-sera testimony to be 
              reliable, it would have to be given involuntarily; but involuntary 
              testimony would violate the legal principle against compelling a 
              suspect to testify, even in his own defense.  Next Winter traces the psychiatric use of two 
              synthesized “truth drugs,” sodium amytal and sodium 
              pentothal, which made patients more communicative. During World 
              War II these drugs were dispensed to treat a mental condition known 
              as “battle exhaustion.” In a classic catch-22, military 
              doctors were taught that the drugs were so powerful, patients who 
              didn’t recover must be faking and were sent back to the front. 
              If the treatment worked, the soldiers were considered better and 
              also were sent back to the front. After the war the applications 
              for these drugs changed yet again, when CIA researchers experimented 
              with a “lie serum”—a “technique for fabricating 
              memory and even an understanding of one's self”—to brainwash 
              subjects.  Winter’s chronological survey, which includes 
              “truth technologies” such as polygraphs and forensic 
              laboratories, concludes with the controversy over recovered memories—from 
              eyewitness testimony to adult memories of childhood abuse—a 
              subject that indirectly inspired the entire project. At the California 
              Institute of Technology, where she taught from 1994 until 2001, 
              Winter was often asked by her scientist colleagues to explain mesmerism 
              in contemporary terms: “Was it like hypnotism is now?” 
              “But hypnosis doesn’t have the broad cultural resonance 
              that mesmerism had in the 19th century,” she says. The closest 
              analogue, Winter decided, was the recovered memory debates, which 
              were “incredibly important in the ‘80s and the early 
              ‘90s.” Ferreting out the truth about truth technologies 
              has been more difficult than Winter anticipated. Partly she was 
              spoiled by the ease of researching the Victorians, who were obsessed 
              with “documenting their own lives,” she says. Many wrote 
              daily letters, preserved the letters in books, and willed the books 
              to descendants. The increasingly tight control over contemporary 
              U.S. government documents makes research more difficult: some CIA 
              files that were once in the public domain, for example, have since 
              been quietly withdrawn. —Carrie Golus, AB’91, AM’93   |  |
