William Moulton Marston

Introduction

William Moulton Marston (May 9, 1893 – May 2, 1947) was an American psychologist, inventor and writer who wrote under the pen name Charles Moulton. He is remembered for three things that rarely belong to the same person: he built one of the first apparatuses intended to detect deception by measuring systolic blood pressure, he published a theory of personality that became the ancestor of the modern DISC assessments used in corporate training, and he created Wonder Woman.

Marston is a difficult figure to place in the history of psychology, and that difficulty is itself the interesting part. He held genuine credentials — a Harvard Ph.D. in psychology in 1921 — and a genuine research programme, but almost none of it survived contact with later evidence. The blood-pressure test was excluded from a federal courtroom in 1923 and has been repeatedly judged inadequate by later scientific reviews; DISC is routinely classified as pseudoscience; and by the 1930s Marston had moved from the laboratory into entertainment, advertising and comics, using his title as a psychologist to sell all three.

Early Life and Education

Marston was born in the Cliftondale section of Saugus, Massachusetts, the son of Annie Dalton (née Moulton) and Frederick William Marston. He went to Harvard and took three degrees there: a B.A. in 1915, graduating Phi Beta Kappa, an LL.B. in 1918, and a Ph.D. in psychology in 1921. The law degree is easy to overlook but explains the direction of much of his applied work, which was aimed at courts, evidence and testimony.

While still an undergraduate he sold a script, The Thief, to the pioneering filmmaker Alice Guy-Blaché, who directed it in 1913 — an early sign of the pull that popular entertainment would exert on him.

In 1915 he married Elizabeth Holloway, who completed her own graduate work and supported the family financially for long stretches. From 1925 Olive Byrne, a former student, lived with the couple in a polyamorous household; Marston had two children with each woman, and Byrne cared for all four. A third partner, Marjorie Wilkes Huntley, was part of the household at times. Both women are usually credited as models for Wonder Woman.

Academic and Professional Career

Marston taught at American University in Washington, D.C., and at Tufts University, while developing his deception research. In 1929 he went to Universal Studios in California as Director of Public Services for a year and taught at the University of Southern California, an early move into the entertainment world that would eventually absorb him.

He also became a public salesman for his own instrument. Marston appeared in advertising — including Gillette razor commercials built around a polygraph motif — presenting the device in a way that conflated demonstration with validation. Later in the 1930s he wrote self-help and popular psychology for magazines.

Wonder Woman

In an interview published in The Family Circle on October 25, 1940, conducted by Olive Byrne under the pseudonym "Olive Richard" and titled "Don't Laugh at the Comics," Marston argued that comic books had substantial educational potential. The piece caught the attention of the publisher Max Gaines, who hired Marston as an educational consultant for the companies that would merge into DC Comics. Marston, adopting the pen name Charles Moulton — his own middle name combined with Gaines's — created Wonder Woman, who first appeared in 1941. He wrote that girls needed a strong female figure to emulate, and that a female character with "all the strength of Superman plus all the allure of a good and beautiful woman" would serve a purpose he described in explicitly psychological terms: submission to loving authority, in his theory, was the route to a stable society.

Marston died of skin cancer on May 2, 1947, in Rye, New York, a week short of his fifty-fourth birthday. He was inducted into the Comic Book Hall of Fame in 2006.

Major Contributions to Psychology

The systolic blood pressure test

Marston's central laboratory finding was that systolic blood pressure, measured continuously, rises with emotional arousal, and that deliberately deceptive answers produce larger rises than truthful ones. His wife suggested the underlying observation: she had noticed that her blood pressure seemed to climb when she became angry or excited. Although she was never listed as a collaborator on the early papers, several historians of the field argue that her role in the work was substantial and has been under-credited.

Marston's test became one component of the modern polygraph, which was assembled by John Augustus Larson in Berkeley, California, combining blood pressure with respiration and galvanic skin response. Marston then tried to commercialise the whole instrument.

DISC theory

In Emotions of Normal People (1928) Marston set out a scheme that later became DISC. He proposed two axes: behaviour is either active or passive, and the environment is perceived as either favourable or antagonistic. Crossing them yields four patterns — Dominance (activity in an antagonistic environment), Inducement (activity in a favourable environment), Submission (passivity in a favourable environment) and Compliance (passivity in an antagonistic environment).

Two things should be said plainly. First, Marston offered no data for the scheme; it is an a priori typology built from introspection, and it is now generally placed among the pseudoscientific personality systems. Second, the modern DISC instruments sold to employers are not Marston's theory in any clean sense — they were constructed later by test publishers, and Marston's own four terms map only loosely onto today's D, I, S and C scales.

A theory of submission

Marston also argued that there is a masculine ideal of freedom that is inherently anarchic and violent, and an opposing feminine ideal grounded in what he called "love allure," leading to willing submission to loving authority. He generalised from his laboratory observation that women in his studies were more honest and more accurate under certain conditions to a broad claim about women's capacities, and presented himself as an advocate for women's potential. The advocacy was real and unusual for its time; the evidence behind it was not.

Major Publications

  • Emotions of Normal People (1928) — the source of DISC and of his claims about gender, using research Byrne had done for her doctorate; it received almost no attention from the academic community, and the one substantive review was written by Byrne herself under her pseudonym.
  • "Systolic blood pressure symptoms of deception" (Journal of Experimental Psychology, 1917) — the empirical basis of the deception test.
  • The Lie Detector Test and related articles and apparatus patents from the 1920s and 1930s.
  • "Don't Laugh at the Comics," The Family Circle (October 25, 1940) — the interview that led to Wonder Woman.
  • The Wonder Woman scripts, written as Charles Moulton from 1941 until his death.

Impact and Legacy

Marston's most durable influence is not in psychology at all. Wonder Woman became one of the few female superheroes with continuous publication since the 1940s, and the character's themes — truth, bondage and liberation, the lasso that compels honesty — are direct expressions of his psychological and personal preoccupations. The lasso is often linked to the polygraph, though a direct derivation is hard to demonstrate.

Inside psychology his residual influence is negative but instructive: he is the standard cautionary example of a credentialed researcher whose instruments outran their evidence and whose authority was then used to sell them.

Why the two surviving claims are both rejected

The polygraph's premise is the problem. There is no physiological response unique to lying. Marston's test measured arousal, and arousal accompanies fear of being disbelieved, anxiety about the situation, anger at the accusation, and the effort of answering — all of which occur in innocent examinees and none of which are deception. A test that counts arousal as deception will always identify the most nervous innocent people as liars.

The courts excluded it early. In Frye v. United States (1923), Marston offered his systolic blood pressure test as evidence and the court refused to admit it, producing the standard for scientific evidence that governed American courts for seventy years — that the method must be generally accepted in its field. His test was on the losing side of the case that created the rule.

Later reviews have been consistently unfavourable. The U.S. National Research Council's 2003 assessment of polygraph validity found accuracy well below the claims made for it, unacceptably high false-positive rates for truthful examinees in screening applications, and no adequate evidence that countermeasures can be defeated. Specific-incident testing performs better than screening, but neither comes close to the reliability Marston's demonstrations implied. Concerns about screening accuracy also drove the federal Employee Polygraph Protection Act of 1988, which sharply restricts private-sector use.

DISC has never been validated. There are no published studies showing that Marston's four patterns predict job performance, and independent reviews of commercially sold DISC instruments have found little or no evidence for their validity. The theory is also unfalsifiable in a practical sense: because any behaviour can be coded into one of four quadrants after the fact, no observation could count against it.

The gender theory carries its own problems. Marston's claim that submission to loving authority is the ideal end state is a normative position, not an empirical finding, and critics have read it as a psychological justification for domination resting on 1920s assumptions about sex roles rather than on data. His assertions about women's greater honesty and accuracy came from unblinded observations in his own laboratory.

Attribution. Emotions of Normal People drew on Olive Byrne's doctoral research without her being credited as co-author; she was left to review it in a journal under a pseudonym. This is now one of the commonly cited instances in psychology of a woman's work being absorbed into a man's publication.

And the conflict of interest. Marston was the researcher, the patent-holder, the commercialiser and the advertising spokesman for the same instrument. When the person who validates a test is also the person who profits from its sale, the validation is not independent — a structural problem that recurs wherever a psychological method is sold as a product.
