How did William Moulton Marston's lie detector research connect to Wonder Woman's golden lasso?

William Moulton Marston, the creator of Wonder Woman, was a psychologist who pioneered early lie detector research. While an undergraduate at Harvard, Marston conducted experiments to determine if systolic blood pressure could indicate deception, a concept he further developed throughout his career.12

The connection between his scientific work and the character's signature weapon is widely recognized by scholars: Wonder Woman’s magic golden lasso compels anyone bound by it to tell the truth. This function serves as a direct thematic parallel to Marston’s professional efforts to develop technology capable of detecting lies. By incorporating this element into the comic, Marston effectively wove his own psychological research into the mythology of his superheroine, who he described as "psychological propaganda" for a new era of female leadership.2
