A Yale University study determined that male jurors are more likely to find an suspect guilty when that suspect is a heavier woman, with thin male jurors the exhibiting the most pronounced bias:
The researchers corralled a group of 471 pretend peers of varying body sizes and described to them a case of check fraud. They also presented them with one of four images—either a large guy, a lean guy, a large woman, or a lean woman—and identified the person in the photograph as the defendant. Participants rated the pretend-defendant’s guilt on a five-point scale. No fat bias emerged when the female pretend peers evaluated the female pretend defendants or when either men or women assessed the guilt of the men. But when the male pretend peers pronounced judgment on the female pretend defendants, BMI prejudice reared up. Jesus wept. The justice system and our basic faith in male decency took another hit.
The study offers further depressing insights. Not only did the male pretend jurors prove “significantly more likely” to find the obese female defendants—rather than the slim ones—guilty, but the trim male participants were worst of all, frequently labeling the fat women “repeat offenders” with “awareness” of their crimes.
