William Moulton Marston's life story is filled with peculiar accomplishments that appear totally unrelated to each other: working successfully as a lawyer and also as a psychologist, he invented the first working lie-detection (polygraph) system. He went on to create the now internationally respected and used DiSC model and wrote several "self-help" books. Amazingly, he also was the creator of the "Wonder Woman" character.
Marston had the benefit of a Classical education and studied the Greek and Roman classics. He was also actively and personally involved during the early days of the struggle for women's rights, addressing issues such as votes for women, birth control, and career equality. Given this altruistic background it is still a surprise to find that one of William Moulton Marston's strangest achievements was the creation of Wonder Woman, the comic book heroine. Wonder Woman's dauntless behaviour that enables her to accomplish her missions so well, are an interesting reflection of the primary DISC characteristics: dominance, influence, submission, and compliance.
Marston was a physiological psychologist with a Ph.D from Harvard University and began his research on what would become the DiSC system early in the twentieth century. In 1928 he published Emotions of Normal People which defined his theory that normal people's behavioural characteristics could be broadly categorised into four main types: Dominance, Inducement, Submission, and Compliance (these classifications have subsequently been "fine-tuned" and now are shown as: Dominance, Influence, Steadiness and Compliance)
The Polygraph: Marston, during his studies, noticed fluctuations in blood-pressure when test subjects were lying. In response to this he conceived a device to measure these changes and therefore give an idea of the veracity of the subject's responses and in 1917 he published his initial "lie-detector" or polygraph findings.
He was a very active lecturer the 1920s and 30s and often consulted with government representatives. Marston's emphasis, unlike many of his fellow psychologists at the time, was on the behaviour of the "general population" ("normal people") whereas most of his peers were more interested in "abnormal psychology". Publishing his findings widely and bringing his methodology to the attention of the court system, he soon gained a reputation for effective analysis and was even involved with the Lindbergh kidnapping case, offering his knowledge to the Lindbergh family.
Marston's research into finding ways to measure the energies involved with behaviour and conscienceless directly led to the development of the DiSC system. Marston himself did not develop assessment tests himself, other colleagues went on to develop the tests that are the forerunners of today's modern DiSC tests.
Ever the pragmatist, he used his knowledge and applied it in the world of cinema, working in 1930 with Universal Studios to help them make the move from the overly melodramatic silent-movies to the new "talkies" which now not only used sound, but required the actors to use more natural gestures, movements and facial expressions.
Marston kept writing new episodes for Wonder Woman until his death in 1947. In 2006 he was enrolled into the Will Eisner Award Hall of Fame.
