Martin Theodore Orne

Orne's main research was concerned with the objective study of subjective states of mind. Of particular significance was Orne's characterisation of the hypnotic state of consciousness, which included a phenomenon called "trance logic". The latter refers to "the apparent tendency of hypnotized individuals to engage simultaneously in logically contradictory or paradoxical thoughts and perceptions and to be oblivious to their incongruity. It has been suggested that trance logic represents evidence of parallel processing in that there appears to be simultaneous registration of information at different levels of awareness" [ APA Dictionary of Psychology, 2022]. Orne devoted much of his career to the investigation of memory distortion and hypnosis. His first published paper focused on issues and myths of hypnosis and age regression in adults. In the 1950s, he published the study "The Social Psychology of the Psychological Experiment" which proved that in most experiments, participants tell experimenters what they want to hear in hopes of pleasing the experimenters.

The Center for Inquiry acquired over 250 boxes of material from Orne's wife. The collection was made available to the public in 2015. The collection contains much of Orne's books and scholarly articles. It is shelved in the CFI's special collections.

Orne was married to psychologist, Emily Carota Orne, whom he collaborated with throughout his career. He had two children, Tracey and Franklin. Orne died of cancer on February 11, 2000, in Paoli, Pennsylvania; he was 72.

Orne founded and directed the Unit for Experimental Psychiatry at the University of Pennsylvania. He was a professor at the university for 32 years becoming a Professor Emeritus in 1996. At the time of his death in 2000, Orne was an Adjunct Professor Emeritus in Psychology and Professor Emeritus in Psychiatry at the University of Pennsylvania.

Orne used the CIA’s money as emergency contingency funds while awaiting grants from other sources. When MKUltra Subproject 84 was discontinued, Orne was allowed to retain the remaining monies, nearly 2/3rds of which he had not yet used.

In 1979, Orne served as a witness in the Bianchi trial. Orne proved that Bianchi lied about having multiple personalities to avoid being prosecuted. Orne tested Bianchi by introducing him to his lawyer who wasn't present. Bianchi interacted with the imaginary lawyer. Orne then brought in his real lawyer which flustered Bianchi and claimed that the imaginary lawyer vanished. Bianchi pleaded guilty in October 1979.

Orne testified as a defense witness during the Patty Hearst trial in 1976; His testimony made the claim that Hearst feared for her life and followed the Symbionese Liberation Army's orders. He later argued that she be pardoned.

Orne became the therapist to the poet Anne Sexton when she was 28. He recorded their sessions and would have Sexton transcribe them as a way to reflect. He also encouraged Sexton to write poetry. Sexton committed suicide in 1974 and the tapes were later passed to Diane Wood Middlebrook, a Sexton biographer. His decision to release the tapes was controversial and met with backlash; he was accused of "dishonoring his profession" although Sexton gave him permission prior to her death and was given consent by Sexton's daughter, Linda Gray Sexton, her literary executor.

Orne was the editor in chief for the journal International Journal of Clinical and Experimental Hypnosis from 1961 to 1992.

He studied at the Bronx High School of Science. He later moved to Boston and studied at Harvard University. Orne enlisted in the U.S. Army during World War II and returned to Harvard afterward. He graduated cum laude in 1948. While at Harvard, he studied under the psychologists Henry Murray and Robert White. Orne received his M.D. degree from Tufts University Medical School in 1955, with a residency in psychiatry at Massachusetts Mental Health Center. In 1958, he received his Ph.D. in psychology from Harvard University.

Martin Theodore Orne (October 16, 1927, Vienna, Austria – February 11, 2000, Paoli, Pennsylvania, US) was a professor of psychiatry and psychology at the University of Pennsylvania. Orne is best known for his pioneering research into demand characteristics, illustrating the weakness of informing participants that they are taking part in a psychology experiment and yet expecting them to act normally. He was well known as a researcher in the field of hypnosis and is also noted for his involvement with the poet Anne Sexton, and with the trials of Patty Hearst and Kenneth Bianchi.

Orne was born on October 16, 1927, to Frank Orne, a surgeon and Martha Brunner, a psychiatrist in Vienna, Austria. His family moved from Austria to escape the Nazi Anschluss and relocated to New York City in 1938.
