In the second study, Mannes showed participants images of four men. Each man was shown twice, once with hair and once without. Not only were the men perceived as more dominant when they were shown digitally balded, but they were also viewed as nearly an inch taller and 13% stronger.

In the final study, Mannes gave the participants verbal and written descriptions men. Some men were described as having thick hair and others had shaved heads. Once again, the participants rated the men with shaved heads highest for masculinity, strength, dominance and leadership potential.

“I was surprised that perceptions of dominance and masculinity extended to concrete, physical characteristics such as height and strength,” says Mannes, whose study was published in the journal Social Psychological and Personality Science.
